Recycling LED Technology from Wavien to reduce picoprojector costs

June 18, 2011
Valencia, CA--Wavien has demonstrated a low-cost LED-based pocket projector or picoprojector that uses Wavien’s proprietary Recycling LED Technology (RLT) in conjunction with a TI DLP chip.

Valencia, CA--At InfoComm 2011 in Orlando, FL (June 15-17), Wavien demonstrated a low-cost light-emitting diode (LED)-based pocket projector or picoprojector that uses Wavien's proprietary Recycling LED Technology (RLT) in conjunction with a 0.45 inch WXGA digital light processing (DLP) chip from Texas Instruments (Dallas, TX). Wavien says its RLT system dramatically reduces the number of components required in the illumination section of the projector, lowering the cost and increasing reliability of the system, which is available from Wavien for licensing to pocket and picoprojector makers.

"Instead of combining light from separate red, green and blue LED packages, Wavien’s RLT technology combines all 3 colored LED’s into a single package. The component count is reduced from the 17 used in traditional systems to component to 6 in this configuration, and potentially to 3 in the next generation," said Kenneth Li, president and CEO of Wavien, who is also the inventor of Wavien’s Dual Paraboloid Reflector (DPR) technology. Li added, "This unique patented design enables a significant reduction in the cost and increase in consistency in manufacturing, which will be a major determining factor for integrating the pico projector into cell phones at high volumes."

Wavien is a technology licensing company developing long-life, high-performance light sources and engine prototypes for the projection and general lighting industries. Wavien currently offers its DPR technology using ultra-high-pressure arc lamps for education and business uses, and xenon lamps for cinema projectors. Wavien has also entered the LED illumination market with its recycling and non-imaging optical technology.
