Difference between laser projector and ordinary projector

1, the type of light source

Ordinary projectors mostly use ultra-high-pressure pump bulb, bulb life in 5000 hours, about 2 years of use. Laser projectors use solid-state lasers as a light source. Laser belongs to the cold light source, the use of the process of heat generation is small, so the projected light source life can reach more than 20,000 hours, that is, at least 8 years of use. Compared with ordinary projectors, one is better than four. In addition, because the laser light source has the characteristics of low exhaustion and high stability, the subsequent replacement cost is also smaller.

2, installation

Generally speaking, the ordinary projector for the space distance requirements are relatively high, most of the need for 3.5 meters in order to throw a 100-inch screen, but also to leave half a meter or so to the wiring, the small family is not very friendly. While the laser projector uses reflective short-focus projection, half a meter can project a large picture of more than 100 inches. Therefore, laser projectors do not need to be suspended like ordinary projectors, and can be used when placed on the TV cabinet, eliminating the tediousness of installation and wiring.

3, anti-environmental light

Ordinary projectors require a certain projection distance, most of the diffuse reflection principle, to avoid direct reflection of the projected light, so the performance of the anti-environmental light is relatively weak. The laser projector is a direct reflection of the light from the laser host into the eyes of the audience, coupled with the need for a small projection distance, so has a better anti-light performance.

Cleaning and Maintenance:

Please turn off the laser projector and unplug the power cord before cleaning. Please use the supplied cleaning cloth or professional cleaning cloth to gently wipe the laser projector body and glass top cover regularly. Do not use abrasive cleaners, solvents and other chemicals or rough objects to wipe the body and glass top cover to avoid corrosion or scratches.

The laser projector is not waterproof, please do not penetrate the liquid into the machine, especially the power indicator, glass cover, heat sink, ports and speaker holes. You need to use the supplied cleaning cloth or professional cleaning cloth to wipe the mirror surface.
