There are several types of projection light sources for projectors, which one is better?

  • 2022-04-14
Friends who are familiar with projectors for the first time will definitely find that some projectors use LEDs as projection light sources, some use lasers as projection light sources, and some use traditional light bulbs as projection light sources. So what kind of projection light source is the best for the projector, let's analyze one by one.

Projector Projection Light Source Type

First of all, let's briefly understand what a projection light source is: the projection light source of a projector is the light emitted by the projection lens, which is the core component of the projector, which determines the brightness, color and light source life of the projector. At present, the projection light sources of projectors are mainly divided into three types: traditional bulb light sources, LED light sources, and laser light sources.

1. Traditional light bulb light source

The traditional light bulb light source mainly adopts high pressure mercury lamp or xenon lamp as the light source.

Advantages: high brightness, good color, mature technology, low cost, easy to replace.

Disadvantages: short lifespan, severe fever, short future development prospects.



2. LED light source

LED light source, also known as light-emitting diode light source, is a kind of cold light source, and it is the main projection light source used in smart micro-projection at present.

Advantages: long life, energy saving and environmental protection, strong stability, light and portable.

Disadvantages: Insufficient brightness and color, not easy to replace.


3. Laser light source

Laser light source is a kind of light source that uses the photoelectric effect to make excited particles emit light under the action of stimulated radiation, and intelligent micro-projection also gradually adopts this kind of light source.

Advantages: high brightness, good color, low energy consumption, strong stability, long life, small size.

Disadvantages: high cost, immature development.



Which projection light source is good

After the above analysis, we can see that although the brightness and color of the traditional bulb light source are relatively good, the shortcomings of short life and heat cannot be ignored. In today's projector industry, it can only occupy a part of the market, and the future development prospects are very general. ; And although the performance of the LED light source is not satisfactory in terms of brightness and color, it has become the mainstream of the projector industry because of its long life and the development of the projector in a smaller and more convenient direction; the laser light source is almost It is the most perfect light source, which combines all the advantages of traditional light bulb light source and LED light source. However, due to the high cost, the development and development are limited. If the price of laser light source can be lowered in the future, it will become the mainstream of projection light source.

The three light sources have their own advantages and disadvantages. For the pursuit of picture color and brightness, the traditional bulb light source is selected. For the pursuit of portability and long-term use, the LED light source can be selected. If the budget is sufficient, the laser light source can be selected.
