1.The life of the lamp can be at least 50000 H ,which can be as longer as possible under the premise of reasonable applications.
2.Low attenuation of the bulb,5% attenuation in 10000 hours,10% attenuation in 20000 hours as to our experiment right now.
3.Colour can be made gamma correction as to the hardware,the colour can be the same as the natrual light in theory.
4.The power consumption of the projector can be less than 40W.
5.LED projector just needs a few seconds from openning to maximun brightness.
6.LED projector didn't include the infrared ray and ultraviolet radiation,since it can be no influences to the life of liquid screen and plastic optics instruments.
7.LED projector can be dustproof.
8.LED projector's quality can be controlled easily.
