Light source module

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.

Dependencies are inferred from the claim text.
