Abstract
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.
