LED light is the preferred light source for miniature projectors

It has been learned from foreign media that most normal-sized projectors use halogen lamps as their light source, which allows the projector to project a complete color image on the screen in any environment. However, the size of the projector has become smaller and smaller, and the huge halogen lamps have begun to be replaced by some smaller LED lamps. These small lamps have quickly become the preferred source of light for many micro-projector manufacturers. Not only is the LED light incredibly small, it also consumes very little energy, making it an ideal choice for small projectors.

In addition, the life of LED lamps is also long, and the life expectancy is as high as 30,000 hours, while typical halogen lamps can only be maintained between 2000 and 3000 hours. The most important aspect is that the LED lamp is 100% non-toxic and does not contain any harmful substances such as mercury.

However, the only other lamp system currently used for pico projectors is the laser system, which uses three-color lasers to create display technology. However, only a few models now use this type of lamp system, which is much less than the number of LED lights on the market.
