Light guide assembly

Abstract

The invention relates to a light guide assembly. The light guide assembly comprises a light guide sheet and a light diffusion sheet; the light guide sheet is arranged at one end of the light diffusion sheet and is fixedly connected with the light diffusion sheet; and a first reflecting layer is arranged on the upper end surface of the light guide sheet. Compared with the prior art, the light scattering sheet is used for scattering the light irradiated by the light guide sheet and the light reflected by the light guide sheet, so that the light is uniformly emitted from the surface of the light scattering sheet.

Description

technical field [0001] The present invention relates to the field of light guide technology, in particular, to a light guide assembly. Background technique [0002] In the prior art, such as Figure 1 to Figure 3 As shown, an L-shaped light guide is embedded on the corner of the housing. Since the PCBA is located inside the housing, the partial shadow position of the L-shaped light guide shown is not within the direct range of the LED, that is, the position of the L-shaped light guide The lower end cannot be irradiated with light; the light guide strip cannot be evenly illuminated; moreover, since the RBG LED is composed of three primary color lights, when the three primary color light passes through the medium of the light guide strip, if dispersion occurs, it may appear on the light emitting surface Local color cast phenomenon appears on the display, especially the effect of white light will be more obvious; so it is necessary to solve these problems.
