Patent ID: 7896532

Claim:
An LED luminescent device comprising: a light emitting diode (LED) light source comprising first and second trapezoidal LED elements having a light-emitting surface emitting light, with the first and second trapezoidal LED elements each having first and second parallel surfaces, a perpendicular surface extending between the first and second surfaces, and an inclined surface extending between the first and second surfaces, with the inclined surfaces of the first and second trapezoidal LED elements facing each other to form a rectangle, wherein each trapezoidal LED element is a high brightness LED of 200 lm; a reflector facing the light-emitting surface of the first and second trapezoidal LED elements and having multiple reflection surfaces of different curvatures reflecting the light from the light-emitting surface of the first and second trapezoidal LED elements, wherein the reflection surfaces are at a distance of more than 20 mm from the LED light source, wherein the reflection surfaces comprise a first reflection surface disposed over the LED light source; and a second reflection surface disposed in rear of the LED light source, wherein the second reflection surface is an afterglow composite reflection surface; a light shade adjusting the light reflected by the reflector to provide a required light distribution pattern; and a projecting lens projecting the required light distribution pattern, wherein the projecting lens is an aspherical lens.
