Abstract

The invention relates to a light guide component and a light source module, comprising a light guide component and a light group; wherein, the light guide component comprises an incidence surface, a reflection surface and an emittance surface; the incidence surface is extended along the length direction and is provided with the incident curvature in the section direction; the reflection surface is provided with a diffraction part arranged along the length direction, and a reflection layer coated on the diffraction part; the emittance surface is extended along the length direction and has the emittance curvature in the section direction; in addition, the light group comprises a plurality of LED lights which are alternately arranged along the length direction; when the rays emitted by the LED lights of the light group are reflected by the diffraction part of the light guide component, the reflected rays can be diffused and evenly emitted out through the emittance surface.

Description

technical field [0001] The invention relates to a scanning device, in particular to a light guide assembly and a light source module. Background technique [0002] In recent years, in order to solve the problem of long warm-up time of the traditional cold cathode fluorescent lamp (CCFL) light source module, the scanning device has continuously developed and used light-emitting diodes (LEDs) as a new generation of light source, which has become a new type of light source in the industry. A necessary trend. [0003] Such as figure 1 Shown is a conventional scanner 1 using LED lamps as the light source, which includes a main body 11 , a light-transmitting plate 12 , a light source module 13 , mirror sets 14 , and an image capture unit 15 . Wherein, the main body 11 includes a reflective chamber 111; the transparent plate 12 is installed above the main body 11; the light source module 13 is installed on the main body 11 and interposed between the transparent plate 12 and the m...
