The following mainstream projection light sources:
At present, with the development of projector light sources, we have experienced three major categories: bulbs, LEDs, and lasers. Among them, the light bulb machine was widely used in the early years because of its short life, expensive follow-up maintenance, mediocre display effect, and many unstable factors. Later, it was gradually replaced by LED light sources. Of course, there are still some brands that use bulb light sources, but most of the projectors with bulb light sources are commercial and office-based, and relatively few for home use.
At present, the mainstream projector light source is LED light source. Most of the high-end and low-end products on the market use LED light source. Speaking of LED light sources, everyone comes into contact with them every day. It's just that the LED light source of the projector is different from the LED light source in our life. It uses a customized light source, and its brightness is dozens of times higher than that of the daily lighting source, or even higher.
The laser light source is relatively high-end, its brightness is high, and it is not at the same level as light bulbs and LEDs. There are also many kinds of laser light sources, mainly monochromatic lasers, two-color lasers and three-color lasers.
