Abstract

A light source module for an atmosphere light and an ambient glass are provided. The light source module is disposed at an edge of a light-guiding glass. The light source module includes multiple light-guiding blocks and light-emitting diode (LED) particles. The multiple light-guiding blocks are arranged along a side edge of the light-guiding glass to constitute a curved light-guiding structure, and the curved light-guiding structure has a radian matching the side edge of the light-guiding glass. The LED particles are disposed at at least one end of the curved light-guiding structure, and lights emitted by the LED particles are uniformly dispersed by the light-guiding structure to be incident into the light-guiding glass.
