The joint effort will combine OSRAM's LED technology with Wavien's proprietary LED recycling (RLT) to provide low cost, high output LED solutions for pocket projectors and pico-projectors small enough to be integrated into cell phones.
Wavien's RLT technology recaptures light lost in standard optical systems and recycles it back to the system output, transforming it back into useable light. An output improvement, as high as 100%, can be achieved.
Besides providing greatly enhanced screen brightness, the unique recycling technology extends battery life for portable systems, and reduces the heat load for ease of cooling. This performance improvement is provided by either adding a simple reflector with an aperture to standard LED packages or by adding a unique imaging light pipe with an aperture.
The dimensions of the apertures, which determine the amount of recycling, and the total size of the reflector or light pipe can be scaled to meet the user's needs.
"Wavien's LED light recycling technology offers outstanding brightness by recovering and recycling high angle light from the LED that is normally wasted with traditional LED coupling systems," stated Dr. Kenneth Li, president and CEO of Wavien, who is also the inventor of the recycling technology.
Dr. Li added: "This unique design enables LED-based projectors to have increased total brightness by up to 100 percent. Clearly, with such improvements in cost and performance, projectors will be used in locations that were previously not feasible."
