Projection light source type

First let's take a brief look at 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. It determines the brightness, color and light source life of the projector. At present, the projector projection light source is mainly divided into three types: traditional lamp light source, LED light source, laser light source.

Traditional lamp light source

Traditional lamp light source mainly uses high-pressure mercury lamp or xenon lamp as the light source. Most of the well-known projector brands such as BenQ, Epson, and Ubiquity use traditional light bulbs as the projection light source.

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

Disadvantages: short life, serious heat, short future development prospects.

LED light source

LED light source, also known as light-emitting diode light source, is a cold light source, which is the main projection light source used in intelligent micro-projection.

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

Disadvantages: lack of brightness and color, not easy to replace.

Laser light source

Laser light source is the use of photoelectric effect, so that the excited state particles under the action of excited radiation light source. Smart microprojectors are also gradually adopting this light source, such as the Dangbei Mars Pro laser projector.

Advantages: high brightness, excellent color performance, low energy consumption, high stability, long life, small size.

Disadvantages: high cost, immature development. 

To summarize, although the traditional lamp light source is better in terms of brightness and color, the short life span and the shortcomings of heat generation cannot be ignored.

The LED light source, although not as bright and colorful as it could be, has become the mainstream of the projector industry because of its long life and the possibility of making projectors smaller and more convenient.

The laser light source is almost the perfect light source, combining all the advantages of the traditional lamp light source and LED light source, but the development is limited due to the high cost. In the future, laser light source will become the mainstream of projection light source.

Each of the three light sources has its own advantages and disadvantages. You can choose according to your needs. If the budget is sufficient, the laser light source is the optimal choice.
