What is the relationship between projection and light sources?
The price of light source: the projector of new light source is generally more expensive, buy it basically replace the money of traditional light bulb for 5 years, and there are many and totally not worth it.
Life of the light source: This is the least important factor, but both LED and laser take it out. Why doesn't it matter? Even if you have 50 thousand or 100 thousand hours of life in the light source, do you have the same life span as the other parts of your projector? Brother, you do the math, you work daily every 4 hours, 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. What's more, the brightness of LED and laser is only about 60% of the original brightness after two thousand hours. Are you willing to endure half the brightness of projectors for the next 8 to 10 years? Would you rather change it often?
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 source.2, emerging light sources, the so-called LED light source, hybrid light source and laser light source.
