Light guiding assembly

Abstract

The invention relates to a light guiding assembly which forms a light source module with at least one light emitting unit. The light guiding assembly comprises a strip-shaped body comprising two opposite sides and a circumferential face for connecting the two sides, wherein the circumferential face comprises a light emitting part, at least one medium part and at least one light incident part, wherein the medium part is opposite to the light emitting part; the light incident part is adjacent to the medium part; and the light emitting unit is arranged at the light incident part and emits light towards the light incident part, and the incident light rays of the light incident part are reflected to the light emitting part through the medium part. The invention has the advantage that a light source output with excellent uniformity can be obtained at the light emitting part so that the integral fabrication is simpler and easier.

Description

technical field [0001] The invention relates to a light guide assembly, in particular to the structure of the light guide assembly. Background technique [0002] Light-emitting diodes have the advantages of small size, long life, unbreakable, and mercury-free, so they gradually replace fluorescent lamps and incandescent bulbs. However, the light emitting diode is a point light source, and the outgoing angle of the light emitted from the light emitting diode is relatively small, so the light emitting diode is limited in some situations that require surface light source lighting or strip light source. [0003] In view of the above problems, in the prior art, LEDs are combined with a light guide strip to convert point light sources into surface light sources or strip-shaped light sources that meet lighting or device requirements. Such as Figure 7 Shown is a schematic diagram of a light guide strip in the prior art. The light guide bar 70 is a rectangle. The light guide bar 7...

[0004] However, since the light-incident surface 72 faces the light-exit surface 74, the light emitted by the LEDs 800 is directly transmitted from the light-incidence surface 72 to the light-exit surface 74, so it is easy on the light-exit surface 74 The relative positions of these light emitting diodes 800 can be seen as bright spots, which affect the light uniformity of the light emitting surface 74
