1. Adopt Japan optics class resist UV type assemble carbonic acid grease material,high pass through of light,be able to bear high tempertature,endure aging.

2. deep glue ,better third dimension,tooth like grain angle of reflection best transmit light effect(passed optics test).

3. backboard adopt metal plating material,best utter the brightness of the reflect focus tubal.

4. CCFL light tube adopt best advanced Japan import  pole,excelled commonly used flat pole.

5.  aperture adopt Japan advanced and steady irradiance powder,can guarantee life of aperture15000-2000  hours.
