LED LED traffic surface emitting lights with high efficiency and visibility

摘要

Provided is an LED traffic light which comprises: an LED traffic light body having a front panel having a light diffusing sheet and a light converting sheet coated with a reflective material on a front surface of the traffic light and a rear panel confronting with the front panel and fixed to a rear surface of the front panel; a plurality of LED light emitting elements mounted in the rear plate and emitting a predetermined color; and a conversion sheet attached to the front plate in a state of being in close contact with the front plate to diffuse light of a predetermined color emitted from the LED light emitting element, and converting the light of a predetermined color into light of another color. Further, the LED traffic light emits blue light as red, green, and yellow light through the conversion sheet coated with red, green or yellow phosphors, respectively. Therefore, the LED traffic light can have high efficiency with electric power with lower energy consumption power comparing to an existing traffic light, and can have an excellent effect of visibility and heat dissipation due to a surface light source.
