Architectural Lighting Applications Installation Guide

Calculating the wattage of the LEDs to be installed

The following method can also be used to calculate the load on only one power supply or individual sections of the

architectural lighting project. Please note that the “watts per module" value must be taken from the specification sheet of

the appropriate product.

wattage = number of modules X watts per module

total wattage = wattage of module type 1 + wattage of module type 2 + (…)

Applying the distance factor if applicable

If the power supply is installed away from the LEDs, use table 1 below to apply the appropriate distance factor to the wattage of the power supply.

Table 1: Distance Factor for Twisted Pair Extension

The distance refers to the distance between the power supply and the first LED module.

Watts available for LEDs = wattage of the power supply X distance factor

The values given in table 1 are usually enough to do proper distance factor calculations. If the distance between the power supply and the first LED module falls between two columns in table 1, it is possible to calculate the distance factor using linear interpolation.

EXAMPLE

Modules : 95 PolyoptikTM 20˚X20˚ 3000K & 20 PolyoptikTM 180˚X180˚ 3500K

Power supply : LMPS-750 (75W)

Twisted pair extension : 50 ft

Distance factor at 50 ft: 0.77

Wattage 1 =

95 PolyoptikTM 20˚X20˚ 3000K X 1.35 watts

= 128.25 watts

Wattage 2 =

20 PolyoptikTM 180˚X180˚ 3500K X 1.35 watts

= 27 watts

Total wattage =

128.25 watts + 27 watts

= 155.25 watts

Watts available for LEDs = 75 watts X 0.77 = 57.75 watts/power supply

Number of power supplies required = 155.25 watts total/57.75 watts/power supply = 3 LMPS-750 Therefore, to distribute the load equally, install 38 modules on each of the first 2 power supplies and install 39 modules on the third power supply for the total 115 modules.

Total system power consumption = 63 watts + 63 watts + 65 watts = 191 watts

TM

Architectural Lighting Applications Installation Guide

Calculating the number of power supplies your project requires

When using a distance factor use the “watts available for the LEDs” instead of the “wattage of the power supply”. Round the result up to the next integer.

Number of power supplies = total wattage / wattage of the power supply

Please note that HEICO lightingTM’s LMPS-350 and LMPS-DC350 have a wattage of 35 watts and the LMPS-750 has a wattage of 75 watts.

Calculating the system wattage

Take the number of watts of LEDs at the output of each power supply and use the appropriate power curve on figure 8 (p.17) to determine each power supply’s consumption. The average output power can also be used if the load is distributed evenly throughout the power supplies.

Calculating the total system power consumption

The total system power consumption equals the sum of the power consumption of each power supply.

Calculating the cost of electricity for a year for the complete architectural lighting system

Please note that “Price of electricity per kW/h” is according to your local electricity rate.

Determining the system efficiency

Due to the high frequency nature of the output of the LMPS power supplies, the input power factor must be used to determine the system efficiency. Take the input watts of each power supply and use the appropriate power factor curve on figure 9 (p.18) to determine the system efficiency.

Additional Considerations

 Distribute the load equally between multiple power supplies. This ensures a uniform level of light across the power

supplies.

 Contact HEICO lighting  All calculations are theoretical. Measurements made on the real life installations can differ from the calculations.

Architectural Lighting Applications Installation Guide

Calculating the wattage of the LEDs to be installed

The following method can also be used to calculate the load on only one power supply or individual sections of the

architectural lighting project. Please note that the “watts per module" value must be taken from the specification sheet of

the appropriate product.

wattage = number of modules X watts per module

total wattage = wattage of module type 1 + wattage of module type 2 + (…)

Applying the distance factor if applicable

If the power supply is installed away from the LEDs, use table 6 below to apply the appropriate distance factor to the wattage of the power supply.

Table 6: Distance Factor for Twisted Pair With Single Wire Loop

The distance refers to the distance between the power supply and the first LED module.

Watts available for LEDs = wattage of the power supply X distance factor

The values given in table 6 are usually enough to do proper distance factor calculations. If the distance between the power supply and the first LED module falls between two columns in table 6, it is possible to calculate the distance factor using linear interpolation.

EXAMPLE

Modules : 95 PolyoptikTM 20˚X20˚ 3000K & 20 PolyoptikTM 180˚X180˚ 3500K

Power supply : LMPS-750 (75W)

Twisted pair extension : 50 ft ; Single wire loop: 50 ft

Distance factor : 0.50

Wattage 1 =

95 PolyoptikTM 20˚X20˚ 3000K X 1.35 watts

= 128.25 watts

Wattage 2 =

20 PolyoptikTM 180˚X180˚ 3500K X 1.35 watts

= 27 watts

Total wattage =

128.25 watts + 27 watts

= 155.25 watts

Watts available for LEDs = 75 watts X 0.50 = 37.5 watts/power supply

Number of power supplies required = 155.25 watts total/37.5 watts/power supply = 5 LMPS-750 Therefore, to distribute the load equally, install 23 modules on each power supply for the total 115 modules.

Total system power consumption = 40 watts + 40 watts + 40 watts + 40 watts + 40 watts = 200 watts

Architectural Lighting Applications Installation Guide

Calculating the number of power supplies your project requires

When using a distance factor use the “watts available for the LEDs” instead of the “wattage of the power supply”. Round

the result up to the next integer.

Number of power supplies = total wattage / wattage of the power supply

Please note that HEICO lightingTM’s LMPS-350 and LMPS-DC350 have a wattage of 35 watts and the LMPS-750 has a wattage of 75 watts.

Calculating the system wattage

Take the number of watts of LEDs at the output of each power supply and use the appropriate power curve on figure 8 (p.17) to determine each power supply’s consumption. The average output power can also be used if the load is distributed evenly throughout the power supplies.

Calculating the total system power consumption

The total system power consumption equals the sum of the power consumption of each power supply.

Calculating the cost of electricity for a year for the complete architectural lighting project

Please note that “Price of electricity per kW/h” is according to your local electricity rate.

Determining the system efficiency

Due to the high frequency nature of the output of the LMPS power supplies, the input power factor must be used to determine the system efficiency. Take the input watts of each power supply and use the appropriate power factor curve on figure 9 (p.18) to determine the system efficiency.

Additional Considerations

 Distribute the load equally between multiple power supplies. This ensures a uniform level of light across the power

supplies.

 Contact HEICO lighting  All calculations are theoretical. Measurements made on the real life installations can differ from the calculations.

 Factors such as wire construction and the layout and length of the electrical circuit can affect the loading of the power supply. As

those factors are beyond the control of HEICO lightingTM it is the responsibility of the installer to ensure that maximum loading will not be exceeded.

 In wire loop with return configurations the return wire needs to be routed as close as possible from one another and they need to be

tied together at least each foot.

 The user is responsible for proper selection of the electrical conductor type that will be used for the specific application; see the

requirements in technical bulletin #27 “Wiring for architectural applications”.

 Contact HEICO lighting
