Projection light sources commonly used in projectors can be divided into three categories: traditional light sources, LED light sources, and laser light sources.

1. Traditional light source

Traditional light sources mainly refer to high-pressure gas discharge light sources such as UHP (Ultra High Pressure Mercury Bulb), UHE (Ultra High Pressure Mercury Bulb), Xenon Lamp, and Halogen Light. The advantage of this type of light source is that it has higher brightness and is cheaper, but the disadvantages are more obvious, and the life is shorter, only a few thousand hours.

2. LED light source


The LED light source is a light-emitting diode light source. The principle of LED light is different from that of incandescent lamps and gas discharge lamps. The energy conversion efficiency of LED light sources is very high. The energy consumption of LED light sources can be close to 10% of the energy consumption of incandescent lamps. Compared with fluorescent lamps, it can also achieve 50% energy saving effect. In addition, the color gamut of the LED light source is wider and the color saturation is higher. The most important thing is that the service life of the LED light source is up to 60,000 hours. .

3. Laser light source


Laser light source refers to an electric light source that uses excited particles to emit light under the action of stimulated radiation. The main advantages of laser light sources are high brightness, good color, low energy consumption, long life and small size, but it also has its disadvantages. That is expensive, so because of the high cost of laser light sources, the general audience will not choose to use, and naturally the projector manufacturer will not choose. The projectors that use laser light sources are very expensive, basically more than $1500 , and may also need to reduce other configurations to reduce costs.


The three types of light sources have their own advantages and disadvantages. You can buy projectors of these three types of light sources according to your needs.
