What light projector is good?
The price of light source: new light source projectors are generally more expensive, buy it basically replace your traditional 5 years of light bulbs, the money used, there are many, it is not worth it
Light source life: This is one of the most important factors, but LED and laser it out for something. Why not? Even if you have 50 thousand light and 100 thousand hours of life, you have other parts of the projector life? Brother, you do the math, you each working day 4 hour, more than 200 days a year that you use every day, a year down to more than 800 hours, an ordinary light bulb so that you can use for several years. But in two thousand hours after LED and laser brightness is basically only the original 60% or so, you will in the next 8 to 10 years long endure only half of the brightness of the projector? Or would you rather often for new?
The stability of the light source used in projector light source: another important factor is the stable, if the light source projector which changed in 3 minutes and 5 minutes after the bright, dark, who collapsed. While LED and laser light source that there is such a problem, because they are the normal light source, which is working temperature and room temperature is not much, the temperature increases, his work temperature is increased, the temperature is lowered, his temperature is reduced, the luminous efficiency and brightness is up and down, and once the room temperature exceeds 30 degrees, LED and laser life fell sharply, if a long time, they life is not as good as the traditional light source. But the traditional light source does not exist such problems, why? Because the traditional light source temperature is more than 1000 degrees, 5 degrees, then you at room temperature 10 degrees for him, really not what.
At present, the market projector light sources may be divided into two broad categories:1, the traditional light source, namely UHP, UHE, xenon lamp, Lu Suguang and other high-pressure gas discharge light source2, emerging light sources, the so-called LED light source, hybrid light source and laser light sourceIn general, the evaluation of the light source of good or bad friends, mainly in the following areas:1, the light source color gamut: This is the most important factor in decision display projector. According to the theory of laser full spectrum color gamut is very wide, LED, but note that the brother said is "full spectrum", because the laser spectrum of human power is very small, most of them can not control, therefore, the laser source used in projector color gamut but is the worst.LED is the same, is limited by the bottleneck of semiconductor technology, can use the projector LED color is also very poor. But because of the history of the development of a traditional light bulb for the past 100 years, the color gamut is wide.
