Abstract
A light source with LED and optical protrusions is provided. It comprises an optical panel and at least one optical plate. The light source can be used together with a heat sink or an optical element to enhance its performance. The optical panel forms an optical surface having plural optical protrusions to reflect and mix lights emitted from the LEDs. The optical plate is inserted into at least one slot on the optical panel, and it comprises a heat dissipation core plate and at least one electric circuit layer. The electric circuit layer comprises LEDs and at least one control circuitry. The electric circuit layer can be attached to either single side or both sides of the heat dissipation core plate. The invention achieves good uniformity and high intensity of the combined lights with desired chromaticity.
