ABSTRACT:
A LED device is provided having a diffuse reflective surface which includes an LED chip emitting light, a reflector cup having the LED chip arranged at a bottom surface thereof and having an angled surface which diffusely reflects the light emitted by the LED chip, and a light conversion material provided in the reflector cup for converting the light emitted by the LED chip into visible light rays. The light-conversion material is spatially separated from the LED chip by a length equal or greater than the maximum length of the LED chip.
