Abstract

A light source module includes a base, a plurality of light emitting components and a reflecting member. The light emitting components is disposed on the base, and the adjacent light emitting components form a gap therebetween. The reflecting member is disposed on the base and surrounded by the light emitting components. The reflecting member has a reflecting surface facing the light emitting components so as to avoid the light from being blocked by the opposite light emitting component and to redirect the light project via the gap formed between the adjacent light emitting components.

Claims

1. A light source module, comprising:

a base having a bottom surface;

a plurality of light emitting components disposed on the base, the light emitting components adjacent to each other forming a gap therebetween, each of the light emitting components emitting a light; and
