Abstract
An LED luminescent device includes an LED light source, a reflector, a light shade and a projecting lens. The LED light source includes at least one LED element having a light-emitting surface emitting light. The reflector faces the light-emitting surface of the at least one LED element and has multiple reflection surfaces of different curvatures reflecting the light from the light-emitting surface of the at least one LED element. The light shade adjusts the light reflected by the reflector to provide a required light distribution pattern. The projecting lens project the required light distribution pattern. Thus, the device and a vehicle lamp including the device can prevent losing light energy.
