Luminus Devices SBT-90 White Big Chip LEDs™ are large, monolithic chips, each with a uniform emitting area of 9mm². Luminus Devices SBT-90 White Big Chip LEDs™ feature an extremely high optical output, a high thermal conductivity package, and Luminus Devices' proprietary Big Chip LEDs™ (PhlatLight®) technology, the name of which is derived from Photonic Lattice. Photonic lattice technology creates true surface emission from the source, which 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. Also available are the SBR-90 LEDs--evaluation modules each consisting of an SBT-90 surface mount device mounted on an aluminum star board.
