RGB LED illumination

Osram and Luminus LEDs with close éntendue matches to DLP Pico DMDs enable brighter, more efficient pico projection systems. For example, Osram CSLNM and Luminus SFT-10 1mm2 RGB LEDs match up well (with an f/1.7 illumination design) with TI’s DLP230GP 0.23-inch quarter high-definition (qHD) DMD.

A three-channel optical design (with separate RGB LEDs) enables the highest possible optical efficiency for smartphone companion projectors, providing high brightness in products with small size and low power constraints.
