How projector lamps works?

Projectors play a huge role in business and education settings these days. With such a strong presence in both the business and education fields, projector lamps are a major staple as well. Now projectors are in more and more homes thanks to Digital Light Processing (DLP) and Liquid Crystal Display (LCD) technology. All projectors consist of a lamp which is the source of light. But how do these projector lamps actually work and what are the different parts to the lamp? To shed some light on this subject (ha!) please continue reading.

The main function of the projector lamp is straightforward and obvious – to provide the bright and intense light that is necessary to have the images provided by the project redirected to the screen or flat surface. The projector supplies the power that is needed to produce this bright light.

There are several other components to the projector lamp which includes electrical wiring, fastener, quartz globe, an ARC tube, spoke, screw and bolt. The projector bulb components are held together by a plastic housing.

Now onto the inner workings of the projector lamps. First across the ARC gap in the projector bulb an electric current is sent which consists of an ultra high pressurized mercury vapor. A very high intensity and brightness is emitted when the electricity that is transmitted lights up the mercury vapor. Finally, fantastic pictures are produced when the light is cast onto LCD or DLP panels.
