Testing of Luminus LEDs

Luminus core board products are typically measured in such a

way that the characteristics reported agree with how the devices

will actually perform when incorporated into a system. This

measurement is accomplished by mounting the devices on a

40ºC heat sink and allowing the device to reach thermal

equilibrium while fully powered. Only after the device reaches

equilibrium are the measurements taken. This method of

measurement ensures that Luminus LEDs perform in the field

just as they are specified.

Expected flux values in real world operation can be extrapolated

based on the information contained within this product data

sheet.

Understanding Luminus LED Test Specifications

Every Luminus LED is fully tested to ensure that it meets the high quality standards expected from Luminus’products.

Luminus LEDTechnology

Luminus’Devices vertical chip LED technology enables large area

LED chips with uniform brightness over the entire LED chip

surface. The optical power and brightness produced by these

large monolithic chips enable solutions which replace arc and

halogen lamps where arrays of traditional high power LEDs

cannot.

PackagingTechnology

Thermal management is critical in high power LED applications.

With a thermal resistance from junction to heat sink of 0.5º C/W,

Luminus CBT-90 LEDs have the lowest thermal resistance of any

LED on the market. This allows the LED to be driven at higher

current densities while maintaining a low junction temperature,

thereby resulting in brighter solutions and longer lifetimes.

Environmental Benefits

Luminus LEDs help reduce power consumption and the amount

of hazardous waste entering the environment. All LED products

manufactured by Luminus are RoHS compliant and free of

hazardous materials, including lead and mercury.

Reliability

Designed from the ground up, Luminus LEDs are one of the most

reliable light sources in the world today. Luminus LEDs have

passed a rigorous suite of environmental and mechanical stress

tests,includingmechanicalshock,vibration,temperaturecycling

and humidity, and have been fully qualified for use in extreme

high power and high current applications. With very low failure

rates and median lifetimes that typically exceed 60,000 hours,

Luminus LEDs are ready for even the most demanding

applications.

Static Electricity

The products are sensitive to static electricity, and care should be

taken when handling them. Static electricity or surge voltage

willdamage the LEDs. It is recommended to wear an anti-

electrostatic wristband or an anti-electrostatic gloves when

handling the LEDs. All devices, equipment and machinery must

be properly grounded. It is recommended that measures be

taken against surge voltage to the equipment that mounts the

LEDs.
