Light source module
A light source module is provided. The light source module includes a lead frame, a light source, a cup part, and a reflector. The light source is disposed on the lead frame, wherein the light source provides a light. The cup part is disposed on the lead frame, wherein the cup part includes an opening, a plurality of thick-wall portions and a plurality of thin-wall portions. The thick-wall portions and the thin-wall portions surround the light source and define a space. The reflector covers the opening. At least a portion of the light is reflected by the reflector, and is emitted through the thick-wall portions and the thin-wall portions.
