Projection Chipset
Technology Overview
Luminus Devices’ Projection Technology is an innovative solid-
state light source created to replace arc lamps in projection
systems. Enabled by unique use of Photonic Lattice technolo-
gy, PhlatLight™ chipsets represent a major breakthrough in
brightness that delivers all the benefits of solid state light
sources in projections applications:
- Wide color gamut for vivid colors, exceeds NTSC.
- Instant turn-on, no more wait time.
- Lifetime of light source at par with TV’s - no more bulb
replacement.
- Environmentally friendly technology - Mercury-free.
- Electronic control of color points and light intensity on
a frame by frame basis
PhlatLight™ products benefit from numerous innovations in the
domain of packaging, thermal management and optical cou-
pling that allow designers to achieve efficient light engine de-
signs and deliver high screen brightness.

Total flux from emitting area at typical dominant wavelength
Based on Type CX package. Small variations in performance may be expected in Type C package due to a higher thermal resistance,
resulting in a higher junction temperature.
Minimum and Maximum Dominant Wavelengths are based on typical values +/- 5nm for Red, +/- 8nm for Green and +/-6nm for Blue

Duty Cycle used to specify device ratings under Pulsed operation. PhlatLight devices can operate at duty cycles ranging from 1% to
100%. At higher duty cycles, drive current should be adjusted to maintain the junction temperature at desired levels to meet the
application lifetime requirements.

Based on maximum allowed current density. Sustained operation beyond recommended drive current values may result in reduced life
time. Thermal calculations should be performed to ensure Tj is maintained below T
jmax
rating or device life may be reduced.
Sustained operation above Maximum Operating Junction Temperature (T
jmax
) may result in reduced device life time.
