Light-emitting module

Abstract

A light-emitting module includes a light guide member, a first reflective paint layer, a first light-absorbing paint layer, a circuit board, and a light-emitting unit. The light guide member includes a positioning surface, a first side surface, a second side surface, and a light emergence surface. The positioning surface includes a groove. The first reflective paint layer is arranged on the first side surface, and the first light-absorbing paint layer is arranged on the first reflective paint layer. The circuit board is located on the positioning surface. The light-emitting unit is arranged on the circuit board and is accommodated in the groove. In this way, the light-emitting unit on the circuit board may change a light path and project light to the light emergence surface, thereby reducing a required stack thickness of the light-emitting module.
