From the first time they power on to their final use before being replaced, high intensity discharge lamps (central to lamp-based projectors) steadily lose fifty percent of their initial brightness capability. While this degradation is an accepted aspect of lamp-based systems, brightness decay affects laser projectors to a much lesser degree. Over the course of their 20,000 hour lifetimes, blue laser diodes only diminish by twenty percent, resulting in greater brightness over dramatically longer periods of use. Furthermore, lasers can achieve significantly greater peak brightness levels than HD lamps, often producing twice as many lumens.
HOW IT WORKS
To generate a full spectrum of color, the 3 primary colors have to be created from a single color laser – in this case, a blue laser. This is achieved by using a cluster of blue lasers that shine onto a spinning yellow and green phosphor wheel that also incorporates a clear segment that allows the blue and green light from the lasers to shine through (this is the blue and green primary color). The generated yellow and green light then passes through a color wheel that in turn generates red – the other primary color. After passing through a diffusion window, the colored light is presented to the Digital Micro Mirror chip, the imaging device. The DMD switches at a very high rate and presents the on, colored pixels to the optical lens system for display on the screen or projected surface.
A simple, precise technology that is efficient and generates sharp, and clearly defined images, as only a single chip is required.
