The PT-120 projection chipset features individually packaged Red, Green and Blue LEDs, each with a monolithic emitting area of 12 mm2, and a 16:9 aspect ratio.

The large emitting area of the PT-120 is designed for projection systems using micro-displays ranging from 0.65" to 1" with wide-screen format. PT-120 is an ideal light source for lamp-free front projectors in home theater, gaming, business or commercial applications.

Like all Luminus projection Big Chip LEDs, the PT-120 can be used with DLP®, LCoS and HTPS LCD micro-displays. PT-120 devices are also available in chipset or individually for high performance illumination applications.


  • 12 mm2 emitting area (4.6 mm x 2.6 mm)
