Midwich launches the world's first mercury-free, high brightness projectors
12th January 2010
Casio has developed the next generation of high brightness projectors using an innovative, mercury-free laser and LED hybrid light source.
Until now, high pressure data projector lamps capable of producing 2000 or more ANSI lumens have contained environmentally harmful mercury. Laser and LED semiconductor light sources do offer promising mercury-free solutions, but because high output sources capable of producing green light have not been feasible for mass production, the have only been applicable for small, low lumen projectors.
In an industry first, Casio has unveiled an original mercury-free hybrid light source capable of generating high brightness by combining a laser, a phosphor and an LED. This groundbreaking innovation achieves high green light output by efficiently converting blue laser light into green light using the phosphor — a stumbling block with previous conventional semiconductor light sources. The high-brightness light of 2000 or more ANSI lumens is achieved by projecting blue laser light, green light converted from blue laser light with the phosphor, and light emitted by a red LED through a DLP® chip onto the screen.
Use of the laser and LED hybrid light source makes Casio’s GREEN SLIM Projectors the world’s first that are powerful enough (2000-3000 ANSI lumens) for projection in a brightly lit room without using a high-pressure mercury lamp. Casio’s GREEN SLIM Projectors will be available in a wide range of options to meet a variety of business needs:
- compact design with the body no bigger than an A4 piece of paper, slim (43 mm) and lightweight (2.3 kg);
- bright colours through upgraded colour purity;
- light source life of approximately 20,000 hours, nearly ten times that of high pressure mercury lamp projectors;
- wide-angle 2X optical zoom allowing use in venues ranging from small meeting rooms to large conference rooms;
- WXGA Real display at 1280 x 800 dots (16:10);
- USB host function for projection without a PC and capability for wireless communication with PCs (XJ-A255/A245/A155/A145/A135);
- projection at maximum brightness is possible within eight seconds of power-on;
- no cool down needed when turning the projector off.
