These breakthroughs allow illumination engineers and designers to achieve solutions that are high brightness and high efficiency. Luminus Technology Reliability Luminus technology enables large area LED chips with uniform Designed from the ground up, Luminus Big Chip LEDs are one of brightness over the entire LED chip surface. The optical power the most reliable light sources in the world today. Big Chip LEDs and brightness produced by these large monolithic chips have passed a rigorous suite of environmental and mechanical enable solutions which replace arc and halogen lamps where stress tests, including mechanical shock, vibration, temperature arrays of traditional high power 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 Big Chip LEDs are ready for even the Thermal management is critical in high power LED applications. most demanding applications. With a thermal resistance from junction to case of 2.45 C/W. Luminus SST-50 LEDs have the lowest thermal Environmental Benefits resistance of any LED on the market. This allows the LED to be driven at higher current densities while maintaining a low Luminus LEDs help reduce power consumption and the amount junction temperature, thereby resulting in brighter solutions of hazardous waste entering the environment. All Big Chip LED and longer lifetimes. products manufactured by Luminus are RoHS compliant and free of hazardous materials, including lead and mercury. Understanding Big Chip LED Test Specifications Every Luminus LED is fully tested to ensure that it meets the high quality standards expected from Luminus products. Testing Temperature Multiple Operating Points Luminus surface mount LEDs are typically tested with a 20 msec The tables on the following pages provide typical optical and input pulse and a junction temperature of 25C. Expected flux electrical characteristics. Since the LEDs can be operated over a values in real world operation can be extrapolated based on the wide range of drive conditions (currents from less than 1.0 A to information contained within this product data sheet. 5.0 A, and duty cycle from <1% to 100%), multiple drive conditions are possible. SST-50 LEDs are production tested at 1.75 A. 2 Luminus Devices, Inc.
