Summary of the chapters

5 / 64

To make it easier to find your way around the Design-in Guide we have grouped the information on the QLE G2 PRE KIT systems into chapters. The guide begins with a system overview in which the different versions of the system are presented. The mechanical, electronic, optical and thermal aspects of the components are then described. At the end of the Design-in Guide you will find ordering information and sources.

2.1. System overview

The QLE G2 PRE KIT system is available with different properties and functions. The relevant components can be clearly assigned by their type codes.

2.2. Mechanical aspects

Depending on the particular situation, the LED Driver can be installed in the luminaire casing (in-built) or outside the casing (remote). Dimensional drawings and installation instructions will help you take account of the requirements of the particular situation.

2.3. Electrical aspects

Special Tridonic connecting cable is available to ensure efficient and reliable connection between the modules and the LED Driver. All the connection options, the connections between the LED Driver and the power supply and the connections of the control lines are shown in relevant wiring diagrams.

2.4. Optical aspects

The overall efficiency of the system is improved by choosing a reflector with suitable optical properties (e.g. beam angle) and dimensions. This chapter provides information to support customer-specific reflector design.

2.5. Thermal aspects

The system modules have been designed to operate with a passive or active heat sink and can be mounted directly on such a suitable heat sink. In the case of active cooling the fan can be connected directly to the module or LED Driver depending on the version.

3.2. Operating functions

QLE G2 PRE KIT offers a wide range of settings for colour temperature and dimming level. Different controllers are available. The controllers are connected directly to the LED Driver.

3.2.1. Central control via the LED Driver

Control via DALI or a switchDIM switch is achieved by connecting these devices to the LED Driver.

Control via DALI

For DALI control the light modules are digitally controlled via the DALI signal (16-bit Manchester Code). The predefined colour temperatures and dimming level can be changed via DALI.

Control via switchDIM

A conventional double pushbutton switch can be used for control via switchDIM. One of the pushbuttons is used to set the colour temperature, the other to set the dimming level. Which button has which function is determined during the installation.

For control via a switchDIM switch different settings can be made:

colorTEMPERATURE modes differ in the position of the individual colour values along the Planckian curve. colourTEMPERATURE mode is tailored to the needs of general and shopping lighting.

On start-up the device first activates colour temperature setting in the colourTEMPERATURE mode. The starting values are a colour temperature of 2,700 K and a dimming level of 100 %.

I NOTICE

The factory preset for colour temperature is 2,700 K, the factory preset for light intensity is 100 %.

½ CAUTION!

The control line must be installed in accordance with the relevant directives on low voltage.

I NOTICE

The control input is protected against polarity reversal and against accidental connection to mains voltage up to 264 V AC.

½ CAUTION!

Pushbuttons with glow lamps affect the switchDIM, colourTEMPERATURE functions and should therefore not be used for this purpose.

Changing predefined colour temperatures and dimming levels

The predefined colour temperatures and dimming levels in colourTEMPERATURE mode can be changed via the masterCONFIGURATOR. Any fixed values within the two limit values of 2,700 K and 6,500 K can be selected for the colour temperature. Adjustments could be in the minimum range step of 100 K. Either a colour value along the Planckian curve can be selected. Up to 16 scenes can be individually defined. These scenes are stored in the LED Driver. They can then be recalled via DALI and switchDIM.

A DALI environment is needed for the configuration (power supply, DALI USB). For more information on the procedure see the masterCONFIGURATOR handbook.

Protection measures in regards to sealing

The points above also apply to chemicals used for sealing luminaire casings. If however the LED module is not installed in the luminaire until after the sealing compound has been completely cured (see relevant material information) the above points can be ignored. If the LED modules have already been installed in the luminaire, possible damage to the encapsulant can be reduced to a minimum by ensuring adequate spacing (>10 cm) and ventilation (open casing and air circulation, extraction / fan) during the curing process.

Protection measures in regards to cementing

To avoid damaging the LED modules you must not use any tools or exert any pressure on the electronic components or the encapsulant.

Instructions for cementing QLE G2 PRE modules

Preparation

Clean and durable bonding of two materials requires special attention. The following cleaning agents are recommended:

Important aspects

Additional information

QLE G2 PRE modules must not be stuck and restuck time and again without replacing the adhesive tape. Damaged adhesive tapes must be completely removed and replaced by new tapes.

Packaging and transport

QLE G2 PRE Kits from Tridonic are delivered in appropriate packaging. The packaging provides special protection against mechanical damage and ESD (electrostatic discharge). If you need to transport QLE G2 PRE products you should use this packaging.

Carrier material The carrier material must have adequate thermal conductivity (e.g. aluminium). The size of the cooling surface depends on the power of the LEDs, among other things. For information on the cooling surface required, see the appropriate product data sheet.

Adhesive material The carrier material itself plays an important role in selecting the adhesive material. The crucial factors are the coefficient of expansion and compatibility with the base material of the module board (plastic or aluminium). This must be checked in the application in terms of long-term stability, surface contamination and mechanical properties.

Surface quality The carrier material must be uncoated (thermal transport, adhesion) and level at the connection points._

Installation temperature To achieve optimum adhesion we recommend you carry out this work at room temperature._

Duration, optimum adhesive strengths Maximum adhesion is achieved within 48 hours at room temperature; the process is accelerated by heat. In actual practice this means that at the maximum t temperature (approx. 75-85 °C, product-specific)

maximum adhesion is reached after about 12 hours. During the curing period make sure that there is no tensile load on the adhesive connection of the module.

5.2. Electrical safety

5.2.1. Basic classification of protection classes

Depending on the design of the luminaire, the requirements of different electrical protection classes are satisfied:

Luminaires in protection class III (also SELV which stands for Safety Extra Low Voltage) have such low internal voltages that a shock current would be inconsequential. AC voltages with an effective value of up to 50 V AC and direct currents up to 120 V DC are referred to as low voltage (also extra-low voltage and weak current).

Protection class II (non-SELV) applies for luminaires with double insulation, with no protective earth, between the mains circuit and the output voltage or metal casing. Even if the luminaires have electrically conductive surfaces, thanks to their insulation they are protected against contact with other live parts.

Protection class I (non-SELV) applies for luminaires with basic insulation and protective earth. All the electrically conductive casing components are connected via a protective conductor system which is at earth potential.

5.2.2. Basic insulation of QLE G2 PRE modules

The QLE G2 PRE module features basic insulation against earth, i.e., a clearance/creepage distance greater or the same as 3 mm and can be directly assembled on an earthed metal part of the luminaire, also in operation with LCA 50W 350-1050mA DT8 lp PRE und LCA 100W 350-1050mA 2xDT8 lp PRE .

5.2.3. Design measures for satisfying protection class requirements

Not all the components of the QLE G2 PRE KIT system comply with the SELV standard. The voltages can thus be greater than 120 V DC.

5.2.4. Protection class II luminaires

When using a QLE module with NON-SELV level, the following measures are essential in order to achieve protection class II:

5.2.5. Protection class I luminaires

When using a QLE control gear with NON-SELV level, the following measures are essential in order to achieve protection class I:

Reinforced insulation between QLE G2 PRE module and the luminaire casing, e.g., by means of plastic casing or an additional insulating foil between the luminaire casing and the module.

Reinforced insulation between the LED Driver and luminaire casing, e.g., by means of plastic casing_

Use of double-insulated lines_

Protect all electrical contacts against mechanical contact, this can typically be achieved with optics which cannot be removed_

Use of metal casing for the luminaire_

½ DANGER!

The following measures must be followed in order to avoid life threatening situations:

Electrical work on a luminaire with protection class I or II (non-SELV) must only be carried out by an electrically skilled person.

The luminaire must be disconnected from the mains before starting work on it._

Check the luminaire for damage, if there are any signs of damage, the luminaire must be replaced._

5.3. Electrical safety and connection

5.3.1. Electrostatic safety and EMC protection

The LED modules are tested up to a voltage of 8 KV static discharging. Depending on the ambient conditions, appropriate precautionary measures must be taken in order to avoid higher voltages, for example during production or installation.

For good EMC conduct, the lines should be run separately from the mains connections and lines. The maximum secondary line length on the terminals is 2 metres.

5.3.2. Electrical supply and selection of the LED Driver

...

½ CAUTION!

QLE G2 PRE module are not protected against overvoltages, overcurrents, overloads and short-circuit currents! Safe and reliable operation of the LED modules can only be guaranteed in conjunction with a LED Driver which complies with the relevant standards.

QLE G2 PRE module must be supplied by a constant current LED Driver. Operation with a constant voltage LED Driver leads to irreversible damage to the modules! Wrong polarity can damage the QLE G2 PRE module. If a wire breaks or a complete module fails in the case of parallel wiring, the current passing through the other modules increases. This may reduce the service life considerably.

6.3. CRI, Ra and Ri - different colour rendering values

The CRI (colour rendering index) and Ra (arithmetic average) value are different names for the same thing. They are defined as the “effect of an illuminant on the colour appearance of objects by conscious or unconscious comparison with their colour appearance under a reference illuminant”.

Technical Design-in Guide Engine QLE G2 PRE KIT | 01-2019 | 1.0 | en

Optical Aspects

35 / 64

CRI and Ra are determined by a test procedure. In this procedure eight colour samples (R1-R8) are illuminated both by the light in question and by a reference light source and the appearance of the samples under the different lights is compared.

If there is no perceivable difference the light in question will be rated with a maximum value of 100. Differences in appearance result in a deduction from the maximum value. The resulting number is the Ri value and describes the colour rendering for one specific colour sample. The average of all eight Ri values is the CRI or Ra value and describes the general colour rendering of the tested light source.

The eight colour samples consist of different pastel colours and can be found in the table below as TCS (test colour samples) 01-08.

There are six more colour samples: R9 to R14 or TCS09 to 14. They consist of different saturated colours and are not used for the calculation of the Ri, Ra and CRI value. However, these colours, especially R9, do have a special importance in the illumination of meat, fish, vegetables and fruit in retail areas.

In the production of modules chips with different wavelengths . and chip performances are used

Because of this, different phosphor mixtures are needed to achieve the required target coordinates and single Ri values can differ between orders. This is not problematic. What is decisive for the overall impression of the LED module is its CRI value. But if specific single Ri values are required for an application, it must be made clear that these values may change for the reasons stated above. It is also not possible to specify tolerances.

Special LED modules are optimised to illuminate a particular product group (for example, MEAT+ is designed for the illumination of

the CRI or single Ri values does not make sense. beef). In this case, specifying For special LED modules the subjective human perception is the most important factor. The colour coordinates for GOLD, GOLD+, Fresh Meat and MEAT+ are the result of appropriate tests. Single Ri values or the CRI value are not assessed.

6.4. SDCM

The human eye can not only recognise different colours along the black body curve, but also deviations above or below this line. If an LED has a colour temperature of 2,700 K , but is not directly located on the black body curve, it can be perceived as different from another LED with the same colour temperature. To prevent such differences and to assign an LED unambiguously, the chromaticity coordinate must be specified using the x, y coordinates in the colour space chromaticity diagram .

An even more accurate approach is to specify the standard deviation from the target colour, based on levels of MacAdam ellipses. The unit for this is called "SDCM" (abbreviation for "Standard Deviation of colour Matching"). When looking directly into a light source, these differences are perceived more strongly than in a "normal" situation where light is mainly perceived because of its reflections from illuminated surfaces.

Colour differences within one level of the MacAdam ellipses are not visible even when looking directly into the light source. Deviations of two to three levels (<= 3 SDCM) are considered barely perceptible. A value of 3 SDCM is good for LED light sources. For most applications a value of 5 SDCM is still sufficient .

6.5. Binning

Chips and packages from the same production can still show small variations in colour temperature and forward voltage . If the chips are used without pre-selection, these differences can be noticeable and interfere with the appearance.

Binning means that the chips and packages are classified according to their colour temperature and forward voltage. This leads to groups of chips or packages that fall into a very narrow window of tolerance. If LED modules are equipped with such chips and packages differences in appearance can be prevented.

6.6. Secondary Optics

The term Secondary Optics refers to additional optical elements that shape the light output in different forms. Secondary Optics include e.g. reflectors, lenses or covers.

6.7. Coordinates and tolerances (to CIE 1931)

As before, the production process for TALEXX LEDs does without binning. As a result, white LEDs can be produced with normal distribution in the range of a MacAdam-Ellipse 3. Thanks to the proximity to the Planckian curve there are no annoying colour discrepancies. Every module is automatically tested at the final inspection stage to ensure that all the supplied products fall within the agreed specification.

6.7.1. Chromaticity coordinate

LEDs exhibit variations in terms of their exact shade of colour. This means that different “white” LEDs will all shine in a colour that is within the white colour spectrum. But the colours won’t be exactly the same.

These colour differences between LEDs are problematic in areas where the lighting must produce a specified and uniform colour and deviations from that can impair the visual appearance of an installation. Using the chromaticity coordinate helps to avoid such problems by defining the exact shade of colour of an LED.

Technically speaking, the chromaticity coordinate is defined by its three coordinates (x, y, z) within the so called CIE 1931 colour space chromaticity diagram. The CIE 1931 colour space chromaticity diagram represents all the colours that are discernible for humans. Since the three coordinates sum up to 1, two coordinates are sufficient to define a colour and so one one coordinate is sometimes left out.

6.7.2. Colour temperature and Black Body Curve

The Black Body Curve within the colour space chromaticity diagram represents the colours that show when a so-called "black body" is slowly heated.

A "black body" is an "idealised" body which absorbs all light and has no reflected radiation. If a "black body radiator" is slowly heated, it passes through a colour scale from dark red, red, orange, yellow, white to light blue. The definition for the colour temperature of a light source is the temperature where the “black body radiator” shows the same colour.

The colour temperature is measured in Kelvin (K). The most common luminaires have colour temperatures below 3,300 Kelvin (warm white), between 3,300 and 5,300 Kelvin (neutral white) or above 5,300 Kelvin (daylight white).

7.1. Passive cooling

Heat transfer from a heat source to the surrounding cooling medium (e.g. air) depends primarily on the difference in temperature, the effective surface area and the flow rate of the cooling medium. The function of a heat sink is to increase the surface area over which the heat can be dissipated. This lowers the thermal resistance. A passive heat sink works mainly by convection. The surrounding air is heated, which makes it rise, and is replaced by cooler air. Heat pipes can be used as an alternative to cooing with fans. If space is particularly tight, the heat is first conveyed away. The actual heat sink is located at the other end of the heat pipe.

Benefits of passive cooling

7.2. Module cooling

7.2.1. Effect of cooling on the life of the modules

The modules of the Engine STARK QLE system are self-cooling and a heat sink is not required. The life of the module depends to a large extent on the operating temperature. The more that the operating temperature can be reduced, the longer the expected life of the module. If the permitted operating temperature is exceeded, however, the life of the module will be significantly reduced.

7.2.2. Temperature measurement on the module

There is a t point on top of the module for checking the temperature

of the latter: The temperature at the t point can be measured with a simple

temperature probe.

In practice, thermocouples (e.g. B&B Thermotechnik, K-type thermocouple) have proved successful. Such thermocouples can be attached directly to the t point with heat-resistant adhesive tape or a

suitable adhesive. The measured values are recorded by an electronic thermometer (e.g., "FLUKE 51", VOLTCRAFT K202 data logger).

The maximum possible temperature must be determined under worst-case conditions (ambient temperature, installation of the luminaire) for the relevant application. Before the measurement is taken, the luminaire should be operated for at least 4 hours in a draught-free room.

The measurement must be taken in a steady thermal state and in a draughtfree room.

7.2.4. Requirements for the heat sink

Although the operating temperature of the modules is continually monitored during operation and the power is automatically reduced in the event of excess temperature, the modules should not be operated without a heat sink. The heat sinks must be dimensioned to provide adequate cooling capacity. The R value is important for selecting an appropriate heat sink. This value depends on the light output of the module and on the

ambient temperature in which the module is to be operated. The R value of the heat sink must be smaller than the required R

th th

value.

8.1. DSI

8.1.1. Description

DSI (Digital Serial Interface) enables DSI control gear to be controlled. The DSI line can be wired separately via a two-core cable or together with the mains cable in a five-core cable. Communication is not impaired by the mains cable. In contrast to DALI, there is no individual addressing of the ballasts with DSI.

DSI offers a series of benefits:

The main benefits of DSI are the optimisation of energy consumption of extensive groups of luminaires (e.g. in sports stadiums and factories).

switchDIM

48 / 64

8.2. switchDIM

8.2.1. Description

With the switchDIM function it is possible to use the mains voltage as a control signal. The phase of a simple standard mains voltage push button is connected to the terminal marked DA/L and the neutral conductor is connected to the terminal marked DA/N.

Using the function is easy and convenient:

switchDIM is therefore a very simple form of lighting management. It also has a positive effect on material and labour costs.

The device has a switchDIM memory function. This is used, among other things, for storing the last dimming value in the event of interruptions in the power supply. When power returns, the LED is automatically restored to its previous operating state and dimmed to the last value.

8.2.2. Commissioning

Using the switchDIM function

switchDIM is operated by the mains voltage push button.

A short press (50-600 ms) switches the device on or off_

A long press (> 600 ms) fades the connected operating device alternately up and down (between 1 and 100 %)._

½ CAUTION!

Glow switches are not approved for controlling switchDIM. Glow switches may cause the LED Driver to spontaneously switch on or off or make sudden changes in the dimming value.

½ CAUTION!

To ensure correct operation a sinusoidal mains voltage with a frequency of 50 Hz or 60 Hz is required at the terminal. Special attention must be paid to achieving clear zero crossings. Serious mains faults may impair the operation of switchDIM and corridorFUNCTION.

½ CAUTIONS!

A maximum number of 25 operating devices per switchDIM system should not be exceeded. If you have more devices please use DALI or DSI.

I NOTICE

If the corridorFUNCTION is activated the LED Driver is controlled only by motion. To operate the LED Driver via DALI, DSI or switchDIM the corridorFUNCTION must be deactivated.

8.4. DALI

8.4.1. Description

DALI standard

DALI (Digital Addressable Lighting Interface) is an interface protocol for digital communication between electronic lighting equipment.

The DALI standard was developed by Tridonic together with renowned manufacturers of operating and control equipment. Today, these manufacturers belong to the DALI Activity Group which promotes the use and further development of DALI.

The DALI standard is defined in IEC 62386. A test procedure standardised by the DALI Activity Group ensures compatibility between products from different manufacturers. Tridonic products have undergone this test and meet all the requirements. This is indicated by the logo of the DALI Activity Group on the device.

The agreement by the lighting industry to adopt a common protocol has opened up a virtually unlimited number of options. With the right choice of individual DALI components an extremely wide range of requirements can be met, from operating a simple light switch to lighting management systems for entire office complexes with thousands of light sources.

Constant Light Output

55 / 64

8.5. Constant Light Output

8.5.1. Description

The light output of an LED module reduces over the course of its life. The Constant Light Output function compensates for this natural decline by constantly increasing the output current of the LED Driver throughout its life. As a results, a virtually uniform light output is achieved at all times.

For configuration purposes the expected module-specific values for lifetime and residual luminous flux must be specified. The output current is then controlled automatically on the basis of these values. The LED Driver typically starts with an output current ("Required Intensity") that corresponds to the expected residual luminous flux and calculates the increase in the value on the basis of the anticipated lifetime.

If the OTL function is enabled, visual feedback is given as soon as the LED exceeds the expected LED lamp life. If the expected LED lamp life is exceeded, the luminaire flashes for 2 seconds after being switched on.

8.8. Intelligent Temperature Guard

8.8.1. Description

The Intelligent Temperature Guard function provides protection against temporary thermal overloads. It slowly reduces the output if the maximum T temperature is exceeded. This way instant failure of the LED Driver can be prevented. Thermal overload protection is

triggered as soon as the T temperature is exceeded by around 5 to 10 °C. The precise trigger temperature depends on the device.

The value is selected so that the protection function is not performed until there is a significant impact on rated life.

The output is reduced in small stages that are generally imperceptible to the user. The temperature is checked every two minutes.
