Luminus Devices CBT-140 Big Chip Round LED Modules

Luminus Devices CBT-140 Big Chip Round LED Modules are the perfect solution for applications defined by a circular aperture. Such optical architectures, previously mismatched with a traditional square LED, can now be updated with round LEDs which better match the application. These Big Chip Round LED Modules increase system-level efficiency by as much as 30%, enabling customers to use a single LED to replace a 250W HID lamp. They will accelerate the adoption of solid-state technology by displacing conventional light sources in high brightness lighting applications.

Markets and applications that will benefit from Luminus' round LED technology include medical, machine vision, portable, and retail spot lighting. For example, in fiber coupled lighting systems the fiber is round, the optic is round, but the LED has always been square. This has now been resolved with the round LED breakthrough that will enable users to replace the 300W Xenon lamp in an application like endoscopy.

Luminus' photonic lattice 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.

With a thermal resistance from junction to case of 0.59ºC/W, these 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.

Luminus Big Chip LEDs 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.
