Luminus Devices CBT-140 Big Chip Round LED Modules
Luminus Devices CBT-140-W LED Modules are the perfect
solution for applications defined by a circular aperture. These optical
architectures can now be updated with round LEDs which better match the
application. Luminus Round LED Modules increase system-level efficiency
up to 30%, allowing a single LED to replace a 250W HID lamp. This
accelerates solid-state technology by replacing conventional light
sources for high-brightness lighting applications.
from Luminus' round LED technology include medical, machine vision,
portable, and retail spot lighting. Fiber-coupled lighting systems
greatly benefit from a round emitter: the fiber is round, the optic is
round, but the LED has always been square resulting in optical losses,
low overall efficiency, and more complex design. This is resolved with
the round LED breakthrough, replacing the 300W Xenon lamp in
applications like medical endoscopy.
Luminus' monolithic chip 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 0.3ºC/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 with conventional passive cooling, 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. Luminus Big Chip LEDs are ready for even the most demanding applications with very low failure rates and median lifetimes that typically exceed 60,000 hours, .
