Abstract
A light source module is disclosed and includes a carrier, a light-emitting unit, and a lens. The light-emitting unit is disposed on the carrier and has a light-emitting surface. The lens is disposed above the light-emitting unit and has bottom surface and a tapered top surface opposite to the bottom surface. The bottom surface is opposite right to the light-emitting surface. A gap exists between the bottom surface and the light-emitting surface. Therefore, beams emitted by the light-emitting unit are modulated by the lens to be mostly concentrated relatively in a specific radiation angle range and distributed more uniform within the specific radiation angle range, which is conducive to reduction of the glare degree of the light source module.
