This suite of technologies give engineers and system designers the freedom to develop solutions both high in power and efficiency. Luminus Technology Reliability Luminus technology enables large area LED chips to emit Designed from the ground up, Luminus LEDs are one of the photons uniformly over the entire LED chip surface. The intense most reliable light sources in the world today. Big Chip LEDs optical power density produced by these UV LEDs facilitate have passed a rigorous suite of environmental and mechanical designs which replace arc and halogen lamps where arrays of stress tests, including mechanical shock, vibration, temperature 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 For UV devices, Luminus engineers the LEDs to maximize light low failure rates and median lifetimes that typically exceed extraction and to emit with a Lambertian far-field distribution 10,000 hours, Luminus Big Chip LEDs are ready for even the pattern. The design maximizes efficiency and allows for flexible most demanding applications. optical designs. Environmental Benefits Packaging Technology Luminus LEDs help reduce power consumption and the amount Thermal management is critical in high power LED applications. of hazardous waste entering the environment. All LED products With a thermal resistance from junction to heat sink of 0.9C/W, manufactured by Luminus are RoHS compliant and free of Luminus CBT-90-UV LEDs have the lowest thermal resistance of hazardous materials, including lead and mercury. 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. 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 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 22.5 A, and This measurement is accomplished by mounting the devices on duty cycle from <1% to 100%), multiple drive conditions a 40C heat sink and measuring the device while fully powered. maybe listed. This method of measurement ensures that Luminus Big Chip CBT-90-UV devices are production specified at 13.5 A. Driving LEDs perform in the field just as they are specified. devices beyond recommended driving conditions shortens lifetime (see derating curves on page 6). Luminus Devices, Inc.
