In addition to innovating technology to enhance learning, DLP Products is continually focused on lowering projector maintenance. Since first demonstrating lamp-free LED display in power-efficient pocket projectors, pico projectors and 1080p projectors last year at InfoComm, DLP Products along with LED supplier Luminus have helped increase the brightness of LEDs to levels needed to support the first lamp-free projectors.
“Our goal is to enable our customers to provide businesses and schools with lower-cost solutions that provide a more immersive learning experience,” said Roger Carver, manager of DLP’s front projection business. “No lamps to maintain. No filter to clean. No problems.”
DLP technology provides manufacturers with the flexibility to choose any light source, whether LED or lamp. A recent lifetime test conducted by light projection technology company Wavien Inc. demonstrated that Wavien’s patented Dual Paraboloid Reflector (DPR) technology could provide projector lamp life for more than three times the lamp life of other projection technology providers. This further supports DLP’s high reliability and low maintenance regardless of illumination source.
Lamp-Free Projectors at InfoComm
The projection world is seeing a trend toward “Solid State”, or lamp-free projection– using LED phosphors and/or Laser light as the light source, in place of a conventional mercury lamp. This trend is in ample evidence at the InfoComm show this week in Las Vegas, with products on demo from Casio, Panasonic, Optoma, BenQ, and more.
