These breakthroughs allow illumination engineers and designers to achieve solutions that are high brightness and high efficiency. Monolithic Large Chip Technology Reliability Luminus technology enables large area LED chips with uniform brightness over the entire LED chip Designed from the ground up, Luminus LEDs are one of the surface. The optical power and brightness produced by these most reliable light sources in the world today. LEDs have large monolithic chips enable solutions which replace arc passed a rigorous suite of environmental and mechanical stress and halogen lamps where arrays of traditional high power tests, including mechanical shock, vibration, temperature LEDs cannot. 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 Packaging Technology 60,000 hours, Luminus LEDs are ready for even the most Thermal management is critical in high power LED applications. demanding applications. With a thermal resistance from junction to board of 0.25 C/W, Luminus CBT-140 LEDs have the lowest thermal resistance of any LED on the market. This allows the LED to be driven at Environmental Benefits higher current densities while maintaining a low junction Luminus LEDs help reduce power consumption and the amount temperature, thereby resulting in brighter solutions and longer of hazardous waste entering the environment. All LED products lifetimes. manufactured by Luminus are RoHS compliant and free of hazardous materials, including lead and mercury. Understanding Luminus LED Test Specifications Every LED is fully tested to ensure that it meets the high quality standards expected from Luminus products. Testing Temperature Multiple Operating Points Luminus core board products are typically measured in such a The tables on the following pages provide typical optical and way that the characteristics reported agree with how the electrical characteristics. Since the LEDs can be operated over a devices will actually perform when incorporated into a system. wide range of drive conditions (currents from 1A to 28.0A, and This measurement is accomplished by mounting the devices on duty cycles from <1% to 100%), multiple drive conditions may a 40C heat sink and allowing the device to reach thermal be listed. equilibrium while fully powered. Only after the device reaches CBT-140 White LEDs are production tested at 21.0 A. 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. 2 Luminus Devices, Inc.
