Abstract
A light source device includes a substrate, an upper electrode layer and a lower electrode layer respectively disposed on two opposite surfaces of the substrate, a plurality of first conductive posts and second conductive posts embedded in the substrate and having the same number, a light emitter, a surrounding frame surrounding the light emitter, and a light permeable member disposed on the surrounding frame and covering the light emitter. The first conductive posts connect a first upper electrode pad of the upper electrode layer and a first lower electrode pad of the lower electrode layer. The second conductive posts connect a second upper electrode pad of the upper electrode layer and a second lower electrode pad of the lower electrode layer. The light emitter is mounted on the first upper electrode pad and is electrically connected to the second upper electrode pad.
