The red filter, the optical loss of 90%, leaving only 200 lumens of red light. In light of the new design, Lumileds has used a red LED light source 18, including circuit losses, including a total power of 14 watts, the light can produce the same effect.
Automotive LED lights are also important areas of light application. In 1987, China began high in vehicle brake lights, LED response speed as fast (nanosecond), can be early to know the driver of a following vehicle operating conditions, and reduce rear-end accidents.
