OSRAM DULUX® EL lamps are compact fluorescent lamps with integrated electronic control gear for mains voltage from 220 to 240 V. The lamps are available with E14 or E27 screw bases or B22d bayonet bases, which means they are quick and simple direct replacements for ordinary light bulbs. They offer the dual benefits of the comfort of a ordinary light bulb and the economy of a fluorescent lamp. OSRAM DULUX® EL lamps are particular economical. They have a reputation as „longdistance runners“ because they consume very little electricity. At 0.13 €/kWh, none cost more than 1/3 € Cent per hour to run.

OSRAM DULUX® EL is available in LONGLIFE and ECONOMY versions with the following characteristics:

Main areas of application for OSRAM DULUX® compact fluorescent lamps are as follows:

1. In the commercial sector: e. g. restaurants, hotels, ticket offices, foyers, corridors, offices

In view of the enormous savings in electricity and replacement costs, these lamps are ideal for areas where continous lighting is needed.

2. In the domestic sector: e. g. in living rooms and the kitchen.

OSRAM DULUX® EL LONGLIFE are needed if there are high demands to be met in terms of lamp life and frequent on/off switching.

OSRAM DULUX® EL compact fluorescent lamps carry the CE symbol of the EU and comply with all the relevant European standards, in particular the following: – EN 60968 (safety requirements) – EN 60969 (performance requirements) – EN 61000-3-2 (mains current harmonics) – EN 55015 (RFI suppression) – EN 61547 (EMC Immunity Requirements)

1.3.9 OSRAM DULUX®EL LONGLIFE FACILITY

Use with stairwell lighting time switches:

The total power input of multiple OSRAM DULUX®EL FACILITY lamps should not exceed 1/8 of the permitted incandescent lamp load. This value depends on the switch design and cannot be applied to other types of energy saving lamp. In addition to the switching load, the provisions of DIN 18015-2 must also be noted: „…in the case of lighting systems in stairwells of multi-family residences, automatic disconnection circuits must be equipped with a warning function (such as dimming of the lights) to avoid sudden darkness“. The type and design of this warning function have not been standardised.

Known designs:

• Warning function with reduced brightness (dimming): The dimming function is generally achieved by half-wave rectification of the mains voltage. DEL FACILITY is not suitable for this mode of operation.

• Warning signal provided by multiple (double) flashing (interruptions of the current)

before disconnection: The lamp is not likely to suffer damage. The warning signal is noticeably changed by the preheating phase of the DEL FACILITY (approx. 0.4 s). If there is an unsuitable pulse sequence the lamp may go off (at least 0.4 s for each switching operation).

ON time:

For the benefit of the lamp, the ON time should not be less than 3 minutes.

Examples:

a) Incandescent lamp load for 2300 W cutout, the following can be connected:

OSRAM DULUX®EL FACILITY 28 x 10 W or 20 x 14 W

b) Incandescent lamp load for 1000 W cutout, the following can be connected:

OSRAM DULUX®EL FACILITY 13 x 10 W or 9 x 14 W

The high quality brand name compact fluorescent lamp with integrated option for varying the light.

• The lighting level can be varied by simply switching the lamp off and on again. Within 3 seconds the luminous flux is reduced to about 25 % of the rated value. Switching the lamp off and on again takes the lamp back up to 100 % luminous flux, irrespective of how long it is switched off. Recommendation: allow the lamps to burn in at full load for at least 1 minute each time before „dimming to around 25 %“ to achieve stable operation

• Additional energy savings from reducing power consumption to 40 %. For more information see Section 3.5.3 Dimmer operation

• In accordance with IEC regulations, OSRAM DULUX®EL LONGLIFE VARIO can be switched on and off any number of times within its average life of 15000 hours and within its permitted temperature range of +15°C to +50°C without having to be switched off for a certain amount of time before being switched on again

• Not suitable for use with existing dimmer systems, DC power, emergency lighting systems or electronic switches

How it works:

The lamp is controlled by infra-red (IR) radiation. Infra-red radiation is emitted by the sun, remote controls and artificial light sources such as incandescent and halogen lamps. By contrast, fluorescent lamps emit very little IR radiation once they have reached their normal operation state. The light from such lamps does not interfere the IR sensor which could make the lamps flicker or go off.

In the case of sunlight, it can be assumed that the brightness of the visible light is proportional to the intensity of the infra-red radiation. The two sensors on the lamp (behind the red covers) detect the IR radiation in the vicinity of the lamp. A measurement signal is derived from this, and this signal is then evaluated by the electronic circuitry in the lamp:

After a maximum of 30 minutes the translucence of the luminaire is measured.

1.4 Economy

1.4.1 Comparison of operating costs

OSRAM DULUX

EL consumes only about one fifth of the electricity of ordinary light bulbs of comparable light output. These savings from low energy consumption is an important aspect in cost/benefit analyses. In commercial applications, the price of the lamps and their maintenance costs also play a role. A comparison between the operating costs of incandescent lamps and those of the OSRAM DULUX®EL range shows that because of the lower electricity costs and longer life of OSRAM DULUX®EL lamps there are considerable benefits despite the higher purchase price. What’s more, there are savings in maintenance costs (labour costs for replacing lamps), which are much higher for incandescent lamps because of their shorter life, and possible savings in airconditioning costs.

2. Function and technical design

2.1 Generation of light As with all fluorescent lamps, light is generated in an OSRAM DULUX®EL lamp

by low pressure gas discharge. Electrical current is passed between the two electrodes in the tube which is filled with partially ionised gas. The electrons excite mercury atoms to emit short-wave ultra-violet light, which is converted into visible light in the phosphor layer on the inside of the tube (Fig. 2). Different light colours are produced depending on the phosphor mix.

Fig. 2: Generation of light in a fluorescent lamp

Compared with an incandescent lamp, the process described for generating light needs only around 1/4 of the electrical energy (1/5 if electr

onic control gear is used). The presence of mercury in the filler gas is crucial for optimum energy conversion in the light generation process. OSRAM DULUX®EL lamps are designed so that the optimum mercury pressure is achieved in the base-up position at an ambient temperature of 25°C.

2.2 Electronic control gear

2.2.1 Operation

Fluorescent lamps need a voltage pulse of several hundred volts in order to start, and need the current to be limited to several hundred mA in order to continue operating properly. In conventional control gear (CCG operation), these two functions are provided by an inductive resistor (choke) and starter. Chokes for a mains frequency of 50 Hz are large and heavy and cause power losses that in the case of compact lamps may be as much as 40 % of the total power input. Instead of conventional control gear, an OSRAM DULUX® EL lamp has integrated electronic control gear for starting and current limitation. The electronic circuitry is small and lightweight. The lamp starts quickly and without flickering. The power losses are only one third of those of conventional control gear.

Electronic control gear contains a number of functional elements:

Fig. 3: Block diagram of electronic control gear

First, a DC voltage of about 280 V is produced from the 50 Hz mains voltage by a rectifier with a smoothing capacitor. This voltage is converted into a square-wave AC voltage with a frequency of more than 40 kHz in the high frequency generator (oscillator), in which two transistors operate as fast acting switches. Even if electronic control gear is used, current limitation and power setting are still handled by chokes. Because of the high operating frequency, however, they have a very much smaller inductance (owing to impedance Z = H x ω) and smaller dimensions than the ones used with conventional control gear. For the lamp to start properly, a voltage of several hundred volts must be applied. In OSRAM DULUX

EL LONGLIFE lamps the lamp electrodes are heated up to the electrode emission temperature (warm start) prior to starting to achieve long life and tolerance to frequent on/off switching. With the electronic control gear used, these two conditions are met by a series resonance circuit, whose resonating for OSRAM DULUX®EL LONGLIFE lamps is deliberately delayed by a PTC thermistor (preheat phase). In the case of OSRAM DULUX®EL VARIO, OSRAM DULUX®EL FACILITY and OSRAM DULUX®EL SENSOR Plus, preheating of the filament and starting of the lamp are closely controlled by an integrated circuit (OSRAM DULUX®IC). A radio interference filter prevents the generator frequency and its harmonics from affecting the supply cables. Thanks to the electronic control gear, an OSRAM DULUX®EL can be operated on any standard mains frequency and is not affected by fluctuations in the mains frequency. Certain lamp types can also be operated on DC voltage (see 3.5.2).

2.2.2 Energy savings thanks to electronic control gear

Compared with fluorescent lamps with conventional control gear, there are further energy savings of around 20 % with electronic control gear.

This is due essentially to two effects:

• The losses with electronic control gear are only about one third of the losses with conventional control gear.

• The luminous efficacy of a fluorescent lamp shows a significant improvement of around 20 % at high frequencies, with saturation setting it at around 50 kHz.

2.2.3 Visual comfort

The use of electronic control gear also brings photometric benefits that considerably improve visual comfort.

Electrode flickering and luminous ripple, which are normal with conventional control gear, cannot be perceived by the human eye at these high frequencies at which the lamp is operated. The eye therefore does not tire as quickly and the light is more comfortable.

3. Lamp data and lamp properties

3.1 Ignition properties/ start-up/ switching behaviour

Unless otherwise indicated, the following test conditions apply to all the technical data specified in this document:

– Supply voltage 230 V/50 Hz – Lamp installed (Base up), free burning – Ambient temperature 25°C ± 1°C

For OSRAM DULUX

EL lamps, reliable starting is assured in the mains voltage range from 198 V to 254 V and at temperatures from -30°C to +50°C, with the following exceptions:

– OSRAM DULUX®EL LONGLIFE 3 W from +5°C to +50°C – OSRAM DULUX®EL LONGLIFE 5 W from -20°C to +50°C – OSRAM DULUX®EL VARIO from +15°C to +50°C – OSRAM DULUX®EL ECONOMY from -15°C to +40°C – OSRAM DULUX®EL ECONOMY CLASSIC from -15°C to +40°C – OSRAM DULUX®EL ECONOMY GLOBE from -15°C to +40°C – OSRAM CIRCOLUX®EL 24 W T5 from -10°C to +50°C

In contrast to fluorescent lamps with conventional control gear, OSRAM DULUX®EL LONGLIFE lamps start without flickering in less than 1.5 s. This time is needed for preheating the cathodes; at low temperatures this may take up to 2 s. Immediately after starting, the lamp produces around 40 % of its rated luminous flux. At room temperature (25°C) it then takes about 2 minutes for the lamp to reach 90 % of its maximum luminous flux. Thanks to this precise cathode preheating, controlled by the electronic circuitry, the life of OSRAM DULUX®EL LONGLIFE lamps is not significantly affected by frequent on/off switching. For a switching cycle of 30 s on/150 s off, an OSRAM DULUX®EL LONGLIFE can handle more than 500000 switching operations in its lifetime.

The requirement here is that the lamp should remain off for at least two minutes before being switched on again so that the PTC thermistor, which controls the starting process in electronic control gear and which is hot while the lamp is in operation, can cool down. There will be a significant reduction in lamp life if this off time is consistantly less than two minutes.

This does not apply to OSRAM DULUX®EL VARIO, OSRAM DULUX®EL SENSOR Plus or OSRAM DULUX®EL FACILITY. These lamps can be switched on and off without restriction. This makes the OSRAM DULUX®EL FACILITY ideal, for example, for stairwell lighting with automatic switch off. If normal OSRAM DULUX®EL LONGLIFE lamps are to be used for this purpose, we recommend switching over to continuous light during the busy times morning and evening.

Because of their design (cold start within 0.2 s without cathode preheating), OSRAM DULUX®EL ECONOMY lamps should not be used in lighting systems in which the lamps are frequently switched on and off (e. g. stairwell lighting or motion detection systems). For a switching cycle of 30 s on/30 s off, OSRAM DULUX®EL ECONOMY lamps can handle more than 5000 switching operations; the average life is 8000 h for a switching cycle of 165 s on/15 s off.

3. Lamp data and lamp properties

OSRAM DULUX®EL – electronic energy saving lamps

Economical alternatives to ordinary light bulbs Technical Guide

3.2 Start-up current

3.3 Photometric data

3.3.1 Spectral distributions

Contrary to popular belief, frequent switching does not increase energy consumption. At the moment of starting there is a short high surge of current of up to 25 A (approx. 80µs half-value width, to charge the internal smoothing capacitor, VARIO: 48 A). This small amount of energy is not lost, however, but is converted into light.

The relative spectral distribution is determined mainly by the colour appearance. Various types and wattages have little effect on this curve.

The spectral distributions shown are therefore typical of all OSRAM DULUX

lamps of the relevant colour appearance. x axis: mW/(m2x 5 nm x 1000 lx) y axis: Wavelength in nanometres.

Notes on the diagrams: The spectral radiant intensity distributions relate to an illuminance of 1000 lx. This has the advantage that the absolute values of any illuminance can be determined a simply from the following quotient:

Illuminance E (measured) x(y axis value)

1000 lx

The spectral intensities are grouped in wavelength ranges of 5 nanometres. The values integrated across 5 nm are specified, irrespective of actual distributions. This corresponds to the standard that is the basis for all calculations of subsequent results (e. g. colour, colour rendering).

3.4 Temperature influences

3.4.1 Dependence on burning positions and temperatures

OSRAM DULUX

EL LONGLIFE, OSRAM DULUX®EL FACILITY and OSRAM DULUX®EL

SENSOR Plus can be used in a temperature range from -30°C to +50°C.

Exceptions:

OSRAM DULUX®EL LONGLIFE 3 W from +5°C to +50°C OSRAM DULUX®EL LONGLIFE 5 W from -20°C to +50°C OSRAM DULUX®EL VARIO from +15°C to +50°C OSRAM DULUX®EL ECONOMY from -15°C to +40°C OSRAM DULUX®EL ECONOMY CLASSIC from -15°C to +40°C OSRAM DULUX®EL ECONOMY GLOBE from -15°C to +40°C OSRAM CIRCOLUX®EL 24 W T5 from -10°C to +50°C

At lower temperatures than those specified the high starting voltage may destroy the lamp. The thermal load on the components at temperatures above 50°C may lead to the premature failure on the integrated electronic control gear.

The luminous flux of Hg low pressure discharge lamps such as the OSRAM DULUX®EL is dependent on the mercury vapour pressure in the lamp and therefore on the temperature at the coolest point (cf. 2.1). When OSRAM DULUX®EL lamps are used in the base up position, the bends in the tubes act as cold spots. Optimum luminous flux is reached when these bends have a temperature of 45°C. This is the case for base up and horizontal positions at an ambient temperature of 20 to 25°C. In the base down position, the rising heat causes cold spots (controlling the Hg vapour pressure) to form in the cylindrical part of the discharge tube; the highest luminous flux in the base down position is reached when the ambient temperature is around -5°C.

For free-burning lamps the ambient temperature corresponds to the room temperature. If the lamps are operated in luminaires, the temperature in the immediate vicinity of the lamp is crucial for the luminous flux.

3.4.2 Lamp temperatures

The VDE (Association of German Engineers) recommends maximum temperatures at certain critical locations in luminaires to ensure safe operation. Compared with incandescent lamps, the temperatures that occur when OSRAM DULUX

EL are in operation are much lower on the glass itself and on the casing, and therefore in the luminaire. This means that OSRAM DULUX®EL lamps with higher luminous fluxes can be used in luminaires that have been approved for incandescent lamps up to a certain wattage.

3.4.3 Notes on luminaire design

Burning position

Because of the thermal conditions on the lamp there are significant differences in the luminous flux/temperature curve for base down, base up and horizontal burning positions (see 3.4.1). The base down

position is recommended for all applications in

which low ambient temperatures are expected.

If lamps are to be installed in the base down

position in outdoor luminaires it is important to ensure that no water (e. g. condensate in the luminaire) can penetrate into the electronic circuitry between the glass and the base casing. (cf. 3.8/Suitability for outdoor applications)

3. Lamp data and lamp properties

3.5 Power supply

3.5.1 Dependence on mains voltage and mains frequency

OSRAM DULUX

EL lamps operate ideally on AC voltage in the range from 198 V to

254 V (according to DIN IEC 38).

The electrical data of lamps differs according to the mains voltage. The changes are substantial in the case of an incandescent lamp, but minimal in the case of OSRAM DULUX®EL. As the voltage increases, the output and the luminous flux change very little (Fig. 14). This behaviour is welcome in view of the frequent overvoltages in the mains supply. Voltages up to 254 V have virtually no effect on the life of an OSRAM DULUX®EL lamp, in contrast to the situation with incandescent lamps. The luminous efficacy of OSRAM DULUX®EL lamps as a measure of the efficiency with which electrical power is used is virtually unaffected by changes in the mains voltage in the range of - 10 % to +10 %.

3.5.2.1 OSRAM DULUX

EL LONGLIFE 5 W and 7 W

OSRAM DULUX®EL LONGLIFE 5 W and 7 W E27/B22d /E14 can be operated in the usual AC voltage range and also on DC voltage in the 176V DC to 310 V DC range and on battery powered 220/240 V systems.

At a lower threshold voltage of 176 V DC the lamps will start reliably from 5°C to 50°C and are insensitive to overvoltages in the DC system up to 310 V DC. OSRAM DULUX®EL LONGLIFE lamps achieve their rated values in DC operation at around 280 V DC. For other DC voltages the differences are as follows:

Emergency lighting:

OSRAM DULUX®EL LONGLIFE 5W and 7 W are suitable for use in emergency lighting systems. For most emergency lighting systems, VDE 0108 calls for a starting time of less than one second. Since the requirements for restart time with DC voltage are met only if the lamp is at operating temperature, they can only be used for maintained emergency lighting.

3.5.2.2 OSRAM DULUX®EL LONGLIFE FACILITY

OSRAM DULUX®EL FACILITY 10 W and 14 W E27/B22d / E14 can be operated indoors on AC voltage and also on DC voltage in the 176 V DC to 310 V DC range and on battery powered 220/240 V systems.

At a lower threshold voltage of 176 V DC the OSRAM DULUX®EL FACILITY will start reliably at temperatures from -30°C to 50°C. They can handle overvoltages in the DC system up to 310 V DC. The lamps reach their rated values in DC operation at around 280 V DC. For other DC voltage values the differences are typically as follows:

Emergency lighting:

With a starting time of less than 0.5 s, OSRAM DULUX®EL FACILITY lamps are suitable in accordance with VDE 0108 for use in emergency lighting systems in a DC voltage range from 176 V DC to 310 V DC. This applies to both maintained and nonmaintained emergency lighting.

With due regard to the properties of the lamps, the requirements for luminous flux and illuminance in areas such as corridors and stairwells must be met by the system in which lighting designers use OSRAM DULUX®EL FACILITY lamps.

3.5.3 Dimmer operation

3.5.4 Operation on

electronic switches

Brightness control with standard dimmers is not possible with OSRAM DULUX®EL lamps.

The electronic control gear of the lamp contains a rectifier and smoothing capacitor (electrolytic capacitor) in the input circuit. This electrolytic capacitor is always charged to the peak value of the AC voltage; mains current flows only briefly and up to the maximum mains voltage. This design prohibits operation with standard dimmers since leading-edge and trailing-edge dimmers would damage the electrolytic capacitor with their steep voltage rises and associated high peak currents.

In addition, most dimmers require a minimum load of many times that of an OSRAM DULUX®EL lamp so that even with the dimmer fully turned up, its switching element would not find an adequate holding current, with the result that the lamp would be continually switched on and off. This would not only damage the OSRAM DULUX®EL lamp, it may also destroy the dimmer.

As an alternative to external dimmer systems, OSRAM therefore offers the OSRAM DULUX®EL VARIO, the lamp with integrated two-stage brightness control (cf. 1.3.10).

This mode of operation is possible only if certain conditions are met.

Because of the design of the input circuit, current flows only for about 4 ms per mains half-wave (cf. 3.5.3). The peak value of this current is three times the rms value. This high crest factor must be taken into account when operating the lamp with electronic switches. Simple thyristor or triac switches that are triggered only once after zero crossing are not suitable because the OSRAM DULUX®EL does not draw holding current at this point. An ohmic load (such as an incandescent lamp) would have to be operated in parallel with the OSRAM DULUX®EL. This would then ensure the holding current for the electronic switch.

More suitable are electronic switches that do not need a holding current (for example those with a MOSFET as the active switching element), or a relay and contactor.

Note the maximum switch-on current of 25 A for approx 80 µs half-value width (except VARIO: 48 A). A reduction to less than 1 A per OSRAM DULUX®EL is possible if, with appropriate control of the electronic switch, the lamp is only switched on at zero crossing.

The maximum charge taken up in the switch-on current surge is between 0.4 and 3 mAs (depending on the wattage); the maximum energy taken from the source per switch-on current surge is 1 Ws (2 Ws if switch-on takes place at maximum mains value). This applies to OSRAM DULUX®EL LONGLIFE, OSRAM DULUX®EL ECONOMY, OSRAM DULUX®EL FACILITY, OSRAM DULUX®EL SENSOR Plus and OSRAM DULUX®EL VARIO.

3.5.5 Operation on

switches with load relief, spark suppression or glow lamps parallel to the switch path

3.5.6 Operation on

motion detectors

3.5.7 Operation parallel

to uncorrected CCG lamps

OSRAM DULUX®EL lamps cannot be operated on jumpered switches (even at high resistance).

Because of the parallel path to the switch the OFF setting is never fully at high resistance. If incandescent lamps are used this is of no importance. If however all the incandescent lamps are replaced by OSRAM DULUX®EL lamps, then even small currents with the switch in the OFF setting will cause the high-impedance input circuit of the OSRAM DULUX®EL to charge up until the threshold voltage at the electrolytic capacitor for starting the HF generator is reached and the lamp consumes the energy stored in the electrolytic capacitor in repeated attempts to start.

This leads to premature ageing and the brief weak flashes of light are irritating.

Necessary load relief elements have to be wired parallel to the load, and neon lamps for illuminating the switches need to be connected parallel to the mains as permanent lights or parallel to the load as signal lights.

OSRAM DULUX®EL lamps can be operated with motion detectors provided the provisions of Section 3.5.4 (for the switching element of the motion detector) and Section 3.5.5 (for any switch load relief elements parallel to the switch) are met.

If motion detectors are used in highly frequented areas, we recommend either setting the ON time as long as possible to avoid unnecessary on/off switching or installing OSRAM DULUX®EL FACILITY lamps.

For these applications the base down burning position is better than the base up position because the ECG stays cooler and the PTC thermistor cools down faster ready for the next gentle start (cf. Section 3.1).

If the lamps are used outdoors in conjunction with motion detectors, note that at low temperatures low levels of luminous flux will be available immediately after the lamp is switched on. Again, the base down position is better (cf. 3.4.1).

If uncorrected conventional control gear is used (or highly inductive loads) a large voltage surge may be generated when the control gear is switched off at maximum current.

If an OSRAM DULUX®EL is connected in parallel on thee same circuit it will be exposed to a large voltage surge which may destroy it ( see also Section 3.5.13).

3.5.9 Operation on

non-sinusoidal voltage sources

3.5.10 Phase shift

Power factor PF correction

If the OSRAM DULUX

EL lamp is controlled by a BUS system, the requirements of

Sections 3.5.4 and 3.5.5 must be met.

Operation of OSRAM DULUX®EL lamps on non-sinusoidal voltage sources (e. g.square wave and trapezoidal inverters) is not straightforward.

It should be remembered that steep signal edges with square-wave inverters mean additional reverse recovery losses for the rectifier and that frequently observed overshoots by powerful inverters may lead to increased charging currents in the electrolytic capacitor (increased crest factor) and, in the worst case scenario, to significant overvoltages. In the event of a high energy overshoot, the electrolytic capacitor charges up to its peak value.

The rms currents should under no circumstances exceed the values for sinusoidal supply and there should be no overshoots. In selecting the inverter, bear in mind that at the moment its is started an OSRAM DULUX®EL lamp has four times the current draw for less than 100 ms (or up to several seconds if the lamp is started at a low temperature) (temporary overload capacity of the inverter). It must be possible for the electrolytic capacitor (typically 1 to 6,8 µF) to be charged by the inverter (start-up current, stability of the control loop).

The phase shift factor cos ϕ indicates the phase shift between mains current and mains voltage and relates exclusively to the fundamental harmonic (50 Hz). The phase shift of harmonics that occur because of non-sinusoidal current draw is not considered here. OSRAM DULUX

EL lamps have a phase shift factor cos ϕ of ≈ 0,95 (capacitive).

The power factor (λ) is defined as: λ = active power N/(rms current l

rms

x rms voltage U

rms

For OSRAM DULUX®EL LONGLIFE and ECONOMY it is approximately 0.6. This value results from the distorted non-sinusoidal draw (mains current harmonic content) of OSRAM DULUX®EL LONGLIFE and ECONOMY and to a lesser extent from a current/voltage phase shift of the 50 Hz component. For this reason, correction of the power factor by capacitors, which is usual with fluorescent lamps in CCG mode, is not possible.

The actual energy consumption of OSRAM DULUX®EL LONGLIFE and ECONOMY lamps is only 20 % of that of an incandescent lamp of similar light output. It is independent of the power factor and is determine only by the active power, which can be measured by a standard ammeter. The savings of 80 % have a direct impact on fuel consumption (coal, oil, gas) and on emissions from power stations.

Because of the lower power factor of around 0.6, the power consumption of OSRAM DULUX®EL LONGLIFE and ECONOMY lamps is not reduced to 20 % but to around 33 %. This causes an appropriate reduction in current draw and not an increase in the losses between the generator and load, and therefore additional energy savings.

3.5.13 Resistance to electro-magnetic interference and transient overvoltages

3.5.14 Interference from IR remote controls

3.5.15 Bases/holders

Since January 1, 2001 EN 61000-3-2 „Electromagnetic Compatibility (EMC)...“ is the general standard for harmonic currents.

All OSRAM DULUX®EL and OSRAM CIRCOLUX®EL lamps comply with the provisions of EN 61000-3-2.

All OSRAM DULUX®EL and OSRAM CIRCOLUX®EL lamps are RFI suppressed to EN 55015 (identical to CISPR 15). Interference on the mains supply is prevented by the interference suppression filter connected on the incoming side of the electronics.

All OSRAM DULUX®EL and OSRAM CIRCOLUX®EL lamps comply with the immunity requirements defined in EN 61547 relating to external electromagnetic interference.

The discharge characteristics of fluorescent lamps means that a small amount of infrared radiation cannot be avoided. If conditions are less than ideal, particularly if the lamps and the IR receiver are arranged too close to one another, this may lead to interference with IR remote controls. This also depends on the modulation of the radiation emitted by the lamp (operating frequency of the ECG), the modulation frequency and the coding of the signals used for IR signal transmission. The signal-to-noise ratio also plays a role.

If interference occurs, we recommend moving the IR receiver out of the radiation range of the lamp or by making sure it is not exposed to direct light.

The IEC has produced recommendations for avoiding such interference on IR signal transmission equipment. Unfortunately, some old IR signal transmitters operated in the same frequency range as the lamps (about 35 kHz). OSRAM therefore increased the operating frequency of all OSRAM DULUX®EL and OSRAM CIRCOLUX®EL lamps to more than 40 kHz to minimise the risk of interference. The latest generation of IR controlled equipment is now making use of „intelligent“ IR receivers that continue to operate correctly even if they receive IR interference.

OSRAM DULUX®EL LONGLIFE, OSRAM DULUX®EL ECONOMY and OSRAM CIRCOLUX®EL lamps are equipped with E14 or E27 screw bases or with B22d bayonet bases on request and will therefore fit in any standard incandescent lamp fittings.

• Frequent switching – e. g. in stairwell lighting (see 3.1, exceptions: OSRAM DULUX®EL VARIO, OSRAM DULUX®EL SENSOR Plus and OSRAM DULUX®EL FACILITY)

• Excessively short OFF times (PTC thermistor) for OSRAM DULUX®EL LONGLIFE and OSRAM CIRCOLUX®EL

When lamp comes to the end of its life the lamp circuit is broken; the flickering typical of fluorescent lamps operated on chokes and starters does not occur with electronic energy saving lamps.

OSRAM DULUX®EL LONGLIFE and ECONOMY lamps are suitable for outdoor use. However, to protect them from moisture they must be used in enclosed ventilated luminaires that have a drain hole where condensate can escape. If the lamps are used outdoors in winter the luminous flux may be reduced by the low temperatures (see Section 3.4.1).

OSRAM DULUX®EL CLASSIC and OSRAM DULUX®EL GLOBE (LONGLIFE and ECONOMY) in enclosed ventilated luminaires (with drain holes) or semienclosed luminaires are ideal for outdoor use in the base down burning position. If low temperatures are expected, OSRAM DULUX®EL LONGLIFE CLASSIC (1.3.5) or GLOBE (1.3.7) should be used.

OSRAM DULUX®EL LONGLIFE and ECONOMY lamps can also be used in areas where there is a heigthened risk of fire or explosions. The requirement here is that they should be used in luminaires that comply with type of protection „flameproof enclosure“ to EN 50018. The fact that these lamps produce much less heat than incandescent lamps is advantageous here.

Economical alternatives to ordinary light bulbs Technical Guide

3.10 Additional information on OSRAM DULUX

SENSOR Plus

1. Why doesn’t the lamp come on immediately in a darkened room?

• IR (= infra red) radiation from the sun may still be getting into the room

• There is an IR source in the room (such as a light bulb switched on)

• Depending on the IR level it may take up to 45 seconds for the lamp to switch on

2. Can I have several lamps in one luminaire or in neighbouring luminaires?

• Yes, provided the sensors are not pointing directly at the other lamps.

3. How can I test a lamp in a luminaire?

• You can do this by simply applying mains voltage (see Self-test)

• Further testing can only be carried out at considerable cost. Covering the sensors may cause the lamp to go out after 45 seconds. If the sensors are then uncovered again the lamp will switch on again only after a lengthy period of time and will switch off as the ambient brightness increases.

4. In one luminaire the lamp switches on too early in the evening.

• Cause: The luminaire or lamp is pointing east-north-east. In the evening very

little light (and therefore IR radiation) falls on the lamp.

• Remedy: Change the position of the luminaire, change the shade over the

luminaire, turn the sensor towards the source of light.

5. In one luminaire the lamp switches on too late in the morning.

• Cause: The luminaire or lamp is pointing west-north-west. In the morning very

little light (and therefore IR radiation) falls on the lamp. The problem may rest with the design of the luminaire – the sensors may not be „seeing“ and IR radiation.

• Remedy: Change the position of the luminaire, change the shade over the

luminaire, turn the sensor towards the source of light.

6. The lamp flashes at night in the luminaire.

• Cause: An external light source (IR) is interfering with the normal operation of

the lamp or the luminaire cover is the problem.

• Remedy: Change the luminaire cover, turn the sensors towards daylight (IR).

As an OSRAM DULUX IC is used to control the lamp, the life of the lamp will not be significantly affected by frequent on/off switching.

4. OSRAM DULUX®EL

and the environment

4.1 Energy balance

4.2 Substances

Whenever energy is used there is an impact on the environment. This impact principally takes the form of the release of carbon dioxide (CO

) when electricity is generated in fossil fueled power stations (1 kWh of electricity = 1 kg of CO2emissions*). The CO2contributes significantly to the „greenhouse effect“, or global warming.

Saving energy is therefore of utmost importance for environmental protection and for OSRAM.

Compared with ordinary light bulbs, all OSRAM DULUX®EL LONGLIFE and ECONOMY lamps not only save energy during their lives, they need less energy for their manufacture.

* For an assumed efficiency of 37 % (power station + power distribution), a molecular weight for CO2of 44 and a thermal value of 10 kWh per 1 kg of coal (carbon), 1kg CO2is produced per 1 kWh of generated energy.

Like all discharge lamps, OSRAM DULUX®EL LONGLIFE and ECONOMY lamps are enclosed systems in normal use. Apart from emitting light, they therefore can have no impact on the environment. A major substance in discharge lamps that is potentially harmful to the environment is mercury. Without it, however, the lamps would not work. Thanks to a patented dosing procedure, OSRAM has succeeded in reducing the mercury content to less than 3 mg per lamp.

OSRAM DULUX®EL LONGLIFE and ECONOMY lamps contain no radioactive

substances.

What’s more, mercury is released when energy is generated from fossil fuels, which means that in this respect the environmental impact of incandescent lamps is much greater than that of compact fluorescent lamps even allowing for the mercury in the compact fluorescent lamp.

All OSRAM DULUX

EL LONGLIFE and ECONOMY lamps are environmentally friendly products because of their energy savings and the associated reduced environment impact (carbon dioxide and mercury).

4.3 Disposal

4.4 Energy Efficiency Index EEI

In Germany, discharge lamps that contain mercury are classified as waste requiring special supervision (special waste) under the Closed Substance Cycle and Management Act (Kreislaufwirtschaftsgesetz) and its provisions. This means that these lamps have to be disposed of as special waste (EEC Code 060404 Waste containing mercury), apart from small volumes in private households.

Private users should still dispose of their old fluorescent lamps (OSRAM DULUX

)

at local recycling centres or collection points.

European Directive 98/11/EC, Energy labelling of mains voltage household lamps: The EEI (Energy Efficiency Index, e. g. EEI = A), also known as the „Energy Label“, classifies lamps according to their energy efficiency (it does not relate to luminaires however).

The seven classes are defined by certain limit values in light output relative to wattage. Lamps in class A are the most efficient at converting electrical energy into light.

* Reflector lamps are excluded from the Energy Label. B’ Candle version
