Luminus Devices CBT-90 UV Big Chip LEDs™

Luminus Devices CBT-90 UV Big Chip LEDs™ provide ultraviolet light in the 400-410nm wavelength, in a CBT-90 Big Chip LED™ package. These high power UV LEDs feature a suite of Luminus technologies, providing solutions both high in power and efficiency.

Luminus' photonic lattice technology enables large area LED chips to emit photons uniformly over the entire LED chip surface. The intense optical power density produced by these UV Big Chip LEDs™ facilitate designs which replace arc and halogen lamps where arrays of traditional high power LEDs cannot. For UV devices, Luminus engineers the photonic lattice to maximize light extraction and to emit with a Lambertian far-field distribution pattern. The design maximizes efficiency and allows for flexible optical designs.

With a thermal resistance from junction to heat sink of 0.9ºC/W, Luminus CBT-90-UV 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.

As 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 10,000 hours, Luminus Big Chip LEDs are ready for even the most demanding applications.
