Luminus LEDs benefit from a suite of innovations in the fields of chip technology, packaging and thermal management. These

breakthroughs allow illumination engineers and system designers to achieve solutions that are high brightness and high efficiency.

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.

Packaging Technology

Thermal management is critical in high power LED applications.

With a thermal resistance from junction to case of 0.7º C/W,

Luminus PT-54 LEDs can be driven at higher current densities

while maintaining a low junction temperature, thereby resulting

in brighter solutions and longer lifetimes.

Reliability

For high power operation, Luminus LEDs are one of the most

reliable light sources in the world today. All products have

passed a rigorous suite of environmental and mechanical stress

tests, including mechanical shock, vibration, temperature

cycling 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. (Please refer to Luminus’ Reliability

application note for more information.)
