How projector lamps work
Date:[2011-8-24]    Total Reading[2790]次

     

There are many people working in a number of different settings, especially education and business environments, who are using projectors with projector lamps. The fact of the matter is, the most important part of your projector is the projector lamp. In order to take the images or video signal that act as input to your projector and transfer them onto a large screen or surface, the projector lamp is necessary. This is why there are so many different people interested in learning more about exactly how the projector lamp comes into play, with the projection of images and video signal from your projector.

PLAYING A KEY ROLE IN THE PROJECTOR

There are many aspects of a projector lamp that play a role in the projection of images or video from projector, although by far, the most important part is the bulb. Every projector lamp has several different parts, that all work towards housing and helping the bulb to function properly. It’s important to remember that varying types of projectors will use and house the projector lamps in slightly different ways. However,, they all use the bulb and projector lamp for the same reason – in order to transfer video, images, or information on to a large screen or surface.

THE IMPORTANCE OF THE PROJECTOR LAMP

In many instances, the system that the projector uses in order to project imagery is referred to as the illumination system, and the projector lamp is vital to the process of this system. The bulb and projector lamp are housed together and usually located within the projector itself behind an access door, since the projector lamp’s bulb will eventually have to be replaced. This will be necessary when it begins to burn out and is unable to produce the brightness required for projection. Some projector lamps also have two bulbs, which will allow one to act as a backup in case of an emergency.

TYPES OF BULBS AVAILABLE

There are many different types of bulbs that projector lamps use in order to do their job. However, the two most popular are halogen bulbs and metal halide bulbs. Halogen bulbs are typically cheaper, however, they do not last nearly as long as metal halide bulbs, which are a little more expensive. The halogen bulbs, when used in projector lamps, often produce a yellow tint on the imagery that is being projected. This is why many people, especially those using their projectors for home theatre use, have opted for projector lamps that use metal halide bulbs, rather than halogen bulbs. Some large projectors use bulbs that are referred to as Xenon lamps, which are used largely because of the incredible color reproduction they are able to achieve.
