Projector

  Projector, also known as projector, is a device that can project images or videos to the screen. It can play corresponding video signals through different interfaces with computers, VCD, DVD, BD, game consoles, DV and so on.

  Projectors are widely used in homes, offices, schools and entertainment places, according to the different work mode, CRT, LCD, DLP and other different types.
The projector uses traditional high intensity gas discharge light sources (such as ultra-high pressure mercury lamp, short arc xenon lamp, metal halogen lamp) and new light sources represented by LED light source and laser light source. The traditional light source projector usually darkens and yellows the projected image with the attenuation of the light emitted from the light source after a period of use (such as brightness attenuation, color saturation contrast reduction, etc.). In the occasions requiring high image quality, even if the light bulb is still emitting, it has to be replaced. So light decay becomes a major obstacle that the projector using traditional light source cannot overcome. With the development of semiconductor lighting technology and laser technology, LED light source and laser light source not only developed rapidly in the field of lighting, but also obtained a wide range of applications in the display field. LED is the first new light source used in projector products, because LED can make the imaging structure of projector more simple, so small size, easy to carry, simple to use projector products to teaching, business and personal entertainment has brought great convenience. At the same time, as a new kind of laser projection light source, its emergence has solved the use of traditional light source of the projector in the defect of attenuation, color, brightness, power consumption, etc, at the same time, due to its belongs to cold light source, so has the characteristics of that is the bright, fundamentally eliminate the use of traditional light source, needs to wait for boot and light stability.

Routine maintenance:
1. Projection environment light should not be strong, preferably weak light
2. Pay attention to the sequence of power switches
3. There should be a certain interval of time after shutdown and then restart
4. Use a stable power supply voltage
5. Cannot work for more than four hours continuously
6. Abnormal shutdown and sudden power failure are strictly prohibited
7. Dedust regularly
