An LED light source device includes a printed circuit board (PCB) and a plurality of LED light sources located on the PCB and electrically connected with the PCB. The plurality of LED light sources are arranged symmetrically relative to a center point of the PCB, and a distance between every adjacent two LED light sources decreases along a direction away from the center point of the PCB. An optical lens is located over the LED light sources for diverging light from a central one of the LED light sources.

Light emitting diode (LED) light source device having uniform illumination

An LED package includes a substrate, an electrode layer, a light-emitting chip, a reflection cup and an encapsulation. The substrate includes a first surface, an opposite second surface, and two side surfaces. The electrode layer is consisted of a positive electrode and a negative electrode, each of which extends from the first surface to the second surface via a respective side surface. The light-emitting chip is located on the first surface of the substrate and electrically connected to the electrode layer. The reflection cup comprises a first part covering the electrode layer on the side surfaces of the substrate, a second part with a bowl-like shape on the first surface of the substrate and surrounding the light-emitting chip. The encapsulation is filled in the second part of the reflection cup.
