These breakthroughs allow illumination engineers and designers to achieve solutions that are high brightness and high efficiency. Luminus Technology Luminus’ 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. Packaging Technology Thermal management is critical in high power LED applications. With a thermal resistance from junction to case of C/W, Luminus SBT-70 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. Reliability Designed from the ground up, Luminus Big Chip LEDs are one of the most reliable light sources in the world today. Big Chip LEDs 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 Big Chip LEDs are ready for even the most demanding applications. Environmental Benefits Luminus LEDs help reduce power consumption and the amount of hazardous waste entering the environment. All Big Chip LED 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 Luminus surface mount LEDs are typically tested with a 20 msec input pulse and a junction temperature of 25ºC. Expected flux values in real world operation can be extrapolated based on the information contained within this product data sheet. Multiple Operating Points A, A The tables on the following pages provide typical optical and electrical characteristics. Since the LEDs can be operated over a wide range of drive conditions currents from1A to A, and duty cycle from <1% to 100% , multiple drive conditions are listed. SBT-70 White LEDs are production tested at A. The values shown at other current conditions are for additional reference at other possible drive conditions.
