Technical Field

[0001] The utility model relates to the technical field of light guide sheets, in particular to a light guide sheet with an adjustable angle for a front bumper lamp. Background Technique

[0002] With the development of LED light sources in the field of automotive lighting, the application of light guide structures in automotive lighting is becoming more and more common. The light guide structure is no longer exclusive to high-end models. There are various forms of installation and connection of the light guide structure on the vehicle lamp assembly. However, in the prior art, the light guide installation structure of the vehicle lamp is relatively complex, the connection is unreliable, and it is easy to affect the optical performance of the light guide.

[0003] Chinese Patent No. CN218845894U discloses a light guide mechanism for a high-level brake lamp: in this patent, the light emitted by the light source module sequentially passes through a vertical condenser lens, a horizontal condenser lens and an outer lens to form an outgoing light path. In the utility model, the vertical condenser lens collects the divergent light in the vertical direction of the light source module, so that it is concentrated along the outgoing light path to the area to be irradiated. At the same time, the horizontal condenser lens collects and concentrates the divergent light in the horizontal direction to the area to be irradiated, so that the brake lamp can emit light evenly and be concentrated in the area to be irradiated.

[0004] However, in the above technology, although the problem of general long-distance irradiation effect of vehicle lamps is solved, it still has the following defects:

[0005] The light guide angle of the existing vehicle lamps is inconvenient to adjust, the light guide rate is low, and the existing light guide only performs uniform light distribution once at the part where the light is incident. When the distance between the light sources is too large, there are usually dark areas during the lighting process of the light guide, resulting in uneven light emitted from the outgoing surface.

The light guide sheet structure 4 is fixed between the two clamping plates 302. By rotating the clamping plate 302, the angle between the clamping plate 302 and the fixing ear 303 can be adjusted. Then, a fixing bolt is used to fixedly connect the clamping plate 302 through the screw hole 304 to complete the fixed installation of the clamping plate 302 and the light guide sheet structure 4.

[0027] In this embodiment, mounting seats 101 are provided on both sides of the lamp housing 1. The mounting seats 101 facilitate the fixed installation of the lamp housing 1 and the front bumper. A through hole 301 is provided inside the connecting plate 3, and a plurality of through holes 301 are provided. The through holes 301 facilitate the light source 501 to emit light into the light guide sheet structure 4.

[0028] In this embodiment, the light guide sheet structure 4 includes an incident part 401, a light guiding part 402, and an emitting part 403. One end of the light guiding part 402 is connected to the incident part 401, and the other end of the light guiding part 402 is connected to the emitting part 403. The light emitted by the light source 501 first enters from the incident part 401, and then is guided to the emitting part 403 by the light guiding part 402 and emitted.
