One of the problem with todays projection technology is the trade-off between the brightness of the lamp and the use of mercury. Most projectors today use lamps that contain mercury) They produce very bright lights and are great for use in presentations, classroom uses, and home entertainment. However the trade-off is the bulb doesn’t last very long and has to replaced fairly often. There are two problems with this is first the financial cost and the second is the environment cost. Mercury if not disposed of correctly is highly toxic to both the environment and humans. Plus replacing bulbs all the time can get expensive.
Casio Laser and LED Hybrid Light engine has been created to replace the mercury lamp used in data projectors. It is rugged and bright. Previous to this there has always been a trade off between brightness and being environmentally responsible. Mercury lamps are very bright, but have to be changed out often and can damage the environment if not disposed of properly. The new Casio Laser and LED Hybrid combine the blue laser light and a flourescent element to produce a green light. These are combined along with the red light emitted by the LED, than projected thru the DLP chip and finally passed through the projection lens to form the image. This technology has a greater color spectrum then mercury lights. It will lowering the total cost of the projector over time. The estimated saving over 6,000 hours of service is $800. With 5 hours a day of service expected live span of this technology is up to 10 years.
When originally introduced at CES’s 2010 the Casio’s Laser & Light engine could produce up to 2500 lumens, after a year of improvement the new GREEN SLIM models have increased brightness up to 3,000 lumens. The GREEN SLIM line has achieved up to 50 percent increase in Color spectrum compared to mercury-lamp projectors. It also has the Instant Off capability which means no cool down time. Frank Romeo vice-president of Casio Business Projector Division stated that “This technology delivers lower cost of ownership and environmental benefit with no compromise in image quality.”
