A present invention includes at least two light cups and a composite material base. The composite material base comprises a first surface, a second surface and a third surface adjacent to the first surface, and a fourth surface opposite to the first surface. The at least two light cups are formed on the first surface. At least two first metal plates and at least two second metal plates having different polarities and corresponding to the quantity of the light cups are provided on the second surface. One ends of the at least two first and second metal plates individually pass through the composite material base and extend into the light cup to form two electrode contacts, and the other ends of the at least two first metal plates extend to the fourth surface to form an exposed heat dissipation structure.

High heat dissipation light emitting diode package structure having at least two light cups and lateral light emission

A wafer substrate, a light emitting diode (LED) light-emitting layer, a circuit layer and an excitation material layer are included. The LED light-emitting layer includes at least two light-emitting regions, independently distinguished. The circuit layer includes at least two circuit structures that correspond to the at least two light-emitting regions in quantity and are independently controlled. The excitation material layer includes at least one photo-luminescence material, at least one of the at least two light-emitting regions is provided with different photo-luminescence materials, and at least one of the at least two light-emitting regions is not provided with the photo-luminescence material. Accordingly, in the present invention, at least two light colors can be formed over a single wafer substrate through the at least two independently-controlled circuit structures and providing the different photo-luminescence materials.
