Abstract
A high brightness light emitting diode (LED) includes a base, a reflector cap, LED dices, a plastic layer, a lens, and a silicon rubber layer. Conductive terminals extend from the base for connection with an external power source. The base defines a bore receiving the cap with a bottom of the cap exposed. The cap forms a cavity receiving the LED dices, which are electrically connected to the conductive terminals. The plastic layer comprising PPA, LCP, or engineer plastics is filled in the cavity o with ends of the terminals extending beyond the plastic layer. The lens is positioned over the plastic layer and has projections that snugly fit over and engage the base. The silicon rubber layer is interposed between the lens and the base. With such an arrangement, lights from the LED dices can be mixed twice for enhanced uniformity of brightness of the light distribution.
