Mechanical Information

Innovate UNO 24

The array should be fixed with 4x M3 screws tightened to 1Nm. Best thermal results are achieved by using the 4 holes spaced at 27.0mm horizontally and 15.0mm vertically. Reflectors (Ledil ‘Lily’ and ‘Venla’ ranges) can be mounted directly on to the array as indicated above. Further details of the reflectors can be found under ‘Optical Consideration’s on page 8.

Innovate UNO 24 Tile

The array should be fixed with 4x M3 screws tightened to 1Nm.

Optical Considerations

Innovate UNO Arrays have mounting holes to fit Ledil ‘Lily’ and ‘Venla’ ranges of reflectors. See Ledil

website for further information www.ledil.com.

Thermal Resistance The overall thermal resistance of the array from the LED junctions to the back of the board is approximately

0.73K/W for the Innovate 24 and 0.35K/W for the Innovate Uno Plus 36. However, if required, it is possible

to get a more accurate measurement of the junction temperature either from use of a thermocouple*

mounted on the Array, or, if supplied**, from the thermistor. This is detailed below.

* Thermocouple should be glued to the UNO array with a thermally conductive adhesive such as ‘Arctic

Silver’ – see Mechanical Information’ for location.

** Thermistor is fitted as standard on the Innovate UNO Plus, but is an option for the Innovate UNO. F

The thermal resistance from each LED junction to the array thermistor/thermocouple is approximately

13K/W per individual LED. The LED junction temperature (Tj) can be calculated from the

thermistor/thermocouple temperature as follows:

Innovate UNO. Tj = Ttherm +(Pa*13/24)

Innovate UNO Plus – for each channel. Tj = Ttherm + (Ps*13/9)

9

Where:

Tj = LED junction temperature in 0C

Ttherm = thermistor or thermocouple temperature in 0C

Pa = power to the array in W

Ps = power to the respective LED channel in W

Examples:

Innovate UNO running at 18W with a thermistor temperature of 450C

Tj = 45+(18*13/24)= approx. 550C

Innovate UNO running at 38W with a thermistor temperature of 650C

Tj = 65+(38*13/24) = approx. 860C

Innovate UNO Plus RGBW running with 9W Red, 18W Green, 5W Blue and 20W White and a thermistor

temperature of 700C will have junction temperatures as follows:

Red Tj = 70+(9*13/9) = approx. 830C

Green Tj = 70+(18*13/9) = approx. 960C

Blue Tj = 70+(5*13/9) = approx. 770C

White Tj = 70+(20*13/9) = approx. 990C

For further details on thermistor resistance values and associated temperatures see appendix 1.

De-Rating All radiant and luminous flux data is based on a Tj of 650C. Below is table indicating the approximate de-

rating of output in %/0C

Wavelength De-rating %/0C

Blue 455nm 0.17%

Green 530nm 0.22%

Red 615nm 0.85%

White 0.17%

Radiant or Luminous flux at a given Tj:

F=Fd-(Fd*(Tj-65)*D/100)

Where

F = Radiant or Luminous Flux at required Tj in mW or lm as applicable

Fd= Radiant or Luminous Flux from datasheet in mW or lm as applicable

Tj= LED junction temperature in 0C

D= de-rating above

Examples

Innovate UNO Blue 465nm at Tj=950C.

Minimum radiant flux at Tj650C from datasheet = 8957mW.

At Tj=950C Minimum flux = 8957-(8957*(95-65)*0.17/100) = approx.. 8500mW

Innovate UNO Plus Tj=800C.

Red Channel

o Minimum luminous flux at Tj650C from datasheet = 461lm.

o At Tj=800C minimum flux = 461-(461*(80-65)*0.85/100) = approx. 402lm

Green Channel

o Minimum luminous flux atTj650C from datasheet = 809lm

o At Tj=800C minimum flux = 809-(809*(80-65)*0.22/100) = approx. 782lm

Blue Channel

o Minimum luminous flux at Tj650C from datasheet = 216lm

o At Tj=800C minimum flux = 216-(216*(80-65)*0.17/100) = approx. 210lm

White Channel

o Minimum luminous flux at Tj650C from datasheet = 1080lm

o At Tj=800C minimum flux = 1080-(1080*(80-65)*0.17/100) = approx. 1052 lm

Innovate UNO Plus, Red Channel on only, at Tj=500C

Minimum radiant flux at Tj=650C from datasheet = 461lm

At Tj-500C = 461-(461*(50-65)*.85/100) = approx. 520lm

Thermal Management The array must be coupled to an appropriate heatsink/thermal management system using a suitable thermal

interface material e.g. a thermal interface compound, graphite preform or phase-change material.

Note: failure to ensure

the LED junction temperature is kept below the limits set out under ‘Lifetime and Lumen Maintenance’ below, could

result in poor performance and/or early failure of the array.

Handling & Storage ESD precautions must be used when handling these devices. Storage conditions: < 300C < 85% relative

humidity.

Avoid contact with the LED Array surface. To clean, blow with dry air or nitrogen.

11

Lifetime & Lumen Maintenance Lifetime/lumen maintenance is anticipated to have an average of 50,000 hours L70B50F10 provided the LED

junction temperature is kept below 1150C, with the following exceptions:

Red arrays/channels: lifetime/lumen maintenance is anticipated to have an average of 35,000 hours

L70 F10 provided the LED junction temperature is kept below 1100C

UV arrays (wavelength <400nm): lifetime/lumen maintenance is anticipated to have an average of

20,000 hours L70 F10 provided the LED junction temperature is kept below 1150C

This lifetime can be dramatically reduced by material choices in either the manufacture or design of the

fixture or the environment the fixture is placed in during life.

Silicone encapsulation is commonly used by most LED manufacturers, including PhotonStar. The silicone

encapsulation is permeable to gas molecules. The gas molecules, including volatile organic compounds

(VOC’s), halogen and sulfur compounds, can interact with silicone and other components that comprise the

LED module and cause degradation in performance of the LED module. The possibility and extent of

degradation is dependent on the type of chemical, the concentration of the chemical, the temperature

during exposure and the length of time of exposure to the chemical. Additional considerations should be

given to IP rated or “sealed” fixtures that create “air tight environments” around the LED module which can

trap potentially damaging gas molecules from manufacturing processes or subsequent out-gassing of

materials used in the fixture which can then result in long term exposure of the LED module to the

contaminant.

The source of the gas molecules can be out-gassing from polymeric materials such as glues, gaskets, paints

and/or under-cured materials. Materials used inside a fixture with a potential to outgas should be

characterized as part of the fixture design to understand the environment that will be surrounding the LED

module during the fixture lifetime.

Common chemicals that are known to be harmful to LEDs are listed in below. Note that the chemicals

listed below may be found in various states – liquid, gas, and/or solid and all physical states of these

chemicals can be an issue.

Because it is impossible to determine all of the chemicals that may be detrimental to the performance of the

module the list of chemicals above may not be exhaustive. It is the responsibility of the fixture manufacturer

to ensure that any and all materials used in the fixture design or manufacturing process do not cause

damage to the LED module.

For additional information on chemicals that are potentially hazardous to LEDs please refer to the following

industry resource:

Lighting Industry Federation Technical Statement No.49 http://www.lif.co.uk/

* L70B50F10 definition: After 50000 h, at least 50 % of the observed LED modules still show 70 % of the

initial luminous flux with less than 10% operational failure rate.
