Problems solved by technology

However, when the light beam passes through more than one prism sheet and the light beam is fully reflected back to the light guide plate, it will cause light loss, which will reduce the brightness that the light source module can provide

Abstract

The invention discloses a light guide plate and a light source module. The light guide plate comprises a first surface, a second surface, at least one light incidence surface and a plurality of groove groups, wherein the second surface is opposite to the first surface; the light incidence surface is connected with the first surface and the second surface; the groove groups are dispersedly formed on the second surface; each groove group comprises a plurality of bent grooves; each bent groove has a bent inclined reflecting surface and a bent backlight side surface which are connected with each other; the bent inclined reflecting surface is inclined relative to the first surface; the bent grooves in each groove group are bent towards the same direction; and the bent inclined reflecting surface of one of two adjacent bent grooves and the bent backlight side surface of the other one of the two adjacent bent grooves are connected with each other. A light source module is also provided.

Description

【Technical field】 [0001] The invention relates to an optical element and a light source, and in particular to a light guide plate and a light source module. 【Background technique】 [0002] In the existing side light source module, the light guide plate is used to guide the light beam emitted by the light-emitting element disposed beside the light guide plate to the front of the light guide plate to form a surface light source. Generally speaking, when the light beam emitted by the light-emitting element enters the light guide plate through the side of the light guide plate, it will be continuously totally reflected by the upper and lower surfaces of the light guide plate, and be confined in the light guide plate. However, the microstructures on the surface of the light guide plate can destroy the total reflection, so that the light beam enters the upper surface at an angle smaller than the critical angle and penetrates the upper surface. [0003] Although the microstructure...
