Commonly used projector light sources generally have three kinds: traditional light bulb light source, LED light source, and laser light source. In recent years, the diversification trend of the domestic projection market has become more obvious. Business offices, culture and entertainment, education and training, home use, etc., demand for projection equipment is increasing in many markets, and the amount of projection equipment parts and consumables required More, and for the projector, the projection light source is the largest consumables.
Traditional projector lamp light source has not been eliminated after so many years, what are its benefits? Now there are several kinds of projector lamp light sources. Metal halide lamps have low prices and short life spans, and generally do not exceed 2000 hours. After 1000 hours, the brightness of the bulbs will almost attenuate by half, and now they have gradually withdrawn from the ranks of projection lamps. The price of UHE lamp is moderate, it belongs to the type of ultra-high pressure lamp, and the general life time is about 4000 hours. It is generally used for low-grade projectors, and the brightness after long-term use will not attenuate too much, and the performance is relatively smooth. The UHP lamp, which is also an ultra-high pressure lamp, is a little higher in price, but it has a high brightness and a long service life. It is mostly used in higher-end projection products. UHP lamps are also frequently used in home projectors and commercial projectors. The amount is getting higher and higher.
In general, the biggest advantage of the traditional light bulb light source is its balance of brightness and price. The brightness of the projector often determines the performance of a projection product to a great extent. The brightness of traditional light bulbs is much higher than that of LED light sources. It can reach more than 3,000 lumens, and it is not as expensive as the laser source in terms of price. From this point of view, the bulb light source still has great advantages.
The advantages of LED light source in recent years, the development of LED light source is becoming more and more mature, the price is getting lower and lower, and in terms of projectors, the most important significance of LED lights is to open up a new path for the miniaturization of the fuselage , Its portability and simple operating system make it fill the gap that traditional projector can't do, make the projector of LED light source more freedom and more portable.
In terms of lighting, the biggest advantage of LED projectors over traditional light bulbs is their durability. The lifetime of LED light sources is up to 20,000 hours, which is about ten times that of traditional projectors. It can be said that a projector using an LED light source can basically realize that it is not necessary to change the light source within a few years of use. The projection using the LED light source produces a purer light color and a higher color saturation than the bulb light source.
The weakness of the LED light source is that its brightness and the traditional light source have a certain gap, which is why the LED light source can not replace the light source, but want to increase the brightness of the LED light source you need to increase the size of the LED light, and thus lost LED light source advantages of light and small, but the increase in size will become a difficult problem after heat dissipation. But overall, the LED light source is still a kind of projection light source with great development potential.
The high-price laser performance laser is a light source that uses the photoelectric effect to make the excited particles emit light under the stimulated radiation. The laser light source is completely different from the bulb light source and the LED light source. First, the color of the laser is very pure, and its monochromaticity is more than 10 times higher than that of the ordinary light source. This makes the laser light source projection equipment in the color performance capability is much larger than the light source, and the stability is strong, long-term use, the quality will maintain high brightness, color saturation and contrast, the screen color is always the same.
In addition, the laser is excellent in brightness performance. By increasing the number of lasers, it is very easy to achieve a single projector luminous flux of 10,000 to 50,000 lumens or even higher, and the lifetime of the light source is still high, and projection can be achieved. There is no need to replace the light source during the service life of the device.
Laser light source is very good in color performance and brightness, life, but the laser light source is indeed a relatively high cost, laser projectors can only appear in the high-end market, but now the market is not the main share of the laser projector the reason.
On the whole, three kinds of light sources have their own advantages. The light bulb light source has a place in the current projection market due to its mature development, easy replacement, and good brightness. However, the future development prospects are general. The lightness and durability of the LED light source make it widely used in the micro-projection and home projection markets. The laser light source has shown great strength in terms of performance and stability. Among the three light sources, the laser light source has a greater potential for development and better performance. In the future projection market, the laser light source is likely to become the main force of the projection light source.
