Abstract

The invention discloses a light source module. The light source module comprises a light guide plate, at least one lighting element and a lampshade; the light guide plate is equipped with a first surface, a second surface and a light incoming surface; the lighting element is arranged beside the light incoming surface and equipped with a light outgoing surface which faces the light incoming surface; the lampshade covers the lighting element and one end of the light guide plate, close to the light incoming surface; the lampshade comprises a side plate and an upper plate; the lighting element is arranged between the side plate and the light incoming surface; the upper plate is equipped with a first end, a second end relative to the first end, and at least one convex surface; the upper plate is connected with the side plate through the first end; the upper plate covers the lighting element and the part of the first surface, close to the light incoming surface; the convex surface is positioned right above the lighting element and protrudes toward the lighting element; the convex surface extends from one side of the upper plate, close to the first end to the second end. The light source module provides a high-uniformity surface light source.

Description

technical field [0001] The present invention relates to an optical module, and in particular to a light source module. Background technique [0002] With the development of photoelectric technology, the cold cathode fluorescent lamp (cold cathode fluorescent lamp, CCFL) arranged on the side of the light guide plate in the prior art can be replaced by light-emitting diode (light-emitting diode, LED) light bar (light bar) replaced. Since the light emitting diode has the advantages of long service life, low power consumption, and fast response, the performance and service life of the light source module using the light emitting diode as the light source can be improved. [0003] However, due to the directivity of the light emitted by the light emitting diodes, in the area of ​​the light guide plate close to the light emitting diodes, the light received near the optical axis of the light emitting diodes (that is, facing the light emitting diodes) receives more light and forms a...
