Problems solved by technology
[0004] The purpose of the present invention is to overcome the defects of the existing light-emitting structure and provide a light-emitting structure with a new structure. The technical problem to be solved is to provide light incident directions of various angles through the arc-shaped light incident surface, With the setting of the inclined light guide wall, the light can be reflected on the inclined light guide wall to the front end of the inclined light exit surface, and the light can be guided by the light guide wall and the arc-shaped light incident surface toward the upper end of the inclined light exit surface. And the reflection of the middle section, so that the light is evenly transmitted to the entire inclined light-emitting surface, which can effectively avoid the problem of uneven light emission of the light-emitting structure, which is very practical

The invention relates to a light-emitting structure which comprises a light guide element and a light source, wherein the light guide element comprises a cambered light incident surface, a light guide wall, an inclined light guide wall and an inclined light emergent surface; the cambered light incident surface is adjacent to the light guide wall, and the light guide wall is adjacent to the inclined light guide wall; the light source is opposite to the cambered light incident surface and emits light rays, and the light rays enter the light guide element from the cambered light incident surfaceand are uniformly transmitted to the inclined light emergent surface by the light guide wall, the cambered light incident surface and the inclined light guide wall. Accordingly, the invention enablesthe light rays to be averagely transmitted on the whole inclined light emergent surface and can effectively solve the problem of uneven light emission of the light-emitting structure.
Description
technical field [0001] The invention relates to a light-emitting structure, in particular to a light-emitting structure with an inclined light-emitting surface. Background technique [0002] figure 1 is a schematic diagram of an existing light-emitting structure. see figure 1 As shown, the existing light-emitting structure 10 includes a light source 11, a light guide 12, and an inclined light-emitting surface 13. When the light emitted by the light source 11 enters the light guide 12, the light path A will directly pass through the light guide 12 and reach the inclined light-emitting surface. 13. Finally, the light leaves from the inclined light-emitting surface 13, and the light paths B and C first reflect in the light guide 12, and finally reach the inclined light-emitting surface 13 and leave from the inclined light-emitting surface 13. The design of the existing light-emitting structure 10 cannot provide the entire inclined light-emitting surface 13 to emit light even...
