Abstract
An LED package comprises a substrate, a reflector, a light-absorbing layer, an encapsulation layer and an LED chip. The light-absorbing layer is located around the reflector and is able to absorb any light which penetrates through the reflector. Therefore, any vignetting or halation of light from the LED package is prevented. Moreover, the LED package can be constructed on a very small scale with no reduction in its color rendering properties.
