7) can provide continuous large-size screen plane array light source. LED is a planar light source, the light emitting unit is a basic side length of 3 ~ 5mm square package, together very easily LED Downlight become an established area of the surface light source, with good brightness uniformity, if the backlight of a liquid crystal TV source, the auxiliary optical components can be done very simply, the screen brightness uniformity even better;
8) Safety. LED using a 5 ~ 24V low-voltage power supply, very safe, power module design is quite simple;
9) environmental protection. LED light source produces no radiation, no toxic substances like mercury, can be described as green light;
10) earthquake. Planar structure of the LED has a solid internal structure, seismic performance is excellent.
