Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamps, in particular to a vehicle lamp structure with a dual-function multiplexed luminous surface. Background Art

[0002] The rear lights on the market now use a design that multiple functions are reused on one light-emitting surface, such as the rear position lights and brake lights, and the front position lights, front turn signals and daytime running lights.

[0003] However, most of them adopt a single light source and thick-wall optical solution, that is, only one set of light sources and one set of thick walls are set, and the two different color LED lamp beads of the light source are arranged at intervals; this makes it impossible for the headlight structure with multiple light-emitting surfaces to form a three-dimensional lighting effect, and the visual experience is poor. Utility Model Content

[0004] In view of this, the problem to be solved by the present invention is to provide a vehicle lamp structure with a dual-function multiplexed light-emitting surface.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A vehicle lamp structure with a dual-function multiplexed light-emitting surface comprises a columnar long light guide and a light guide plate, wherein a plurality of the light guide plates are vertically constructed in front of the long light guide and arranged along the axial direction of the long light guide, a plurality of light-scattering recesses are constructed on the end surface of the light guide plate facing the long light guide, and a light source is correspondingly arranged at the axial end of the long light guide and the top end of the light guide plate.

[0007] The light guide plate is a bent L-shaped structure, the long light guide is embedded in a V-shaped light guide support frame, the vertical portion of the light guide plate extends along the height direction of the light guide support frame, and the horizontal portion of the light guide plate is located above the light guide support frame.

[0008] A plurality of the light-scattering concave platforms are constructed on the vertical portion of the light guide plate, and the light source surface corresponding to the light guide plate is arranged toward the rear end of the horizontal portion of the light guide plate.

[0009] The rear end of the long light guide is a sawtooth surface.

[0010] The light source is a PCB board with LED lamp beads.

[0011] The advantages and positive effects of the utility model are:

[0012] Compared with the light guide plate, the long light guide has a longer light shape continuity, and can achieve a visual effect of through-lighting when lit. There is a distance between the vertically designed light guide plate and the long light guide and the vertical luminous surface is also larger than the long light guide. Therefore, compared with the long light guide, it can achieve a suspended lighting visual effect when lit. The combination of the two visual effects enables the whole lamp to achieve a three-dimensional lighting effect when in use, thereby increasing the user's visual experience.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0022] like Figures 1 to 4 As shown, the utility model provides a dual-function multiplexed light-emitting surface vehicle lamp structure, including a columnar long light guide 1 and a light guide plate 2, the light guide plate is a light guide thick wall, a plurality of the light guide plates 2 are vertically constructed in front of the long light guide 1 and arranged along the axial direction of the long light guide 1, so that the light guide plate 2 can also be illuminated by the long light guide 1 behind, so as to achieve the effect of multiplexing the light-emitting surface of the light guide plate 2, and a plurality of astigmatism concave platforms 21 are constructed on the end surface of the light guide plate 2 facing the long light guide 1, and the inner surface of the astigmatism concave platform 21 is a non-spherical surface design, which is used to increase the reflection angle and make the light guide plate 2 The internal light is scattered, so that the light guide plate 2 is lit more evenly. The axial end of the long light guide 1 and the top of the light guide plate 2 are correspondingly provided with light sources. The long light guide 1 has a longer light shape continuity relative to the light guide plate 2, and can achieve a visual effect of through lighting when lit. There is a distance between the vertically designed light guide plate 2 and the long light guide 1, and the vertical luminous surface is also larger than the long light guide 1. Therefore, relative to the long light guide 1, a suspended lighting visual effect can be achieved when lit. The combination of the two visual effects enables the entire lamp to achieve a three-dimensional lighting effect when in use.

[0023] Specifically, the long light guide 1 is embedded in the light guide support frame 11 of the V-shaped structure, thereby covering the long light guide 1, preventing light from leaking from the rear end of the long light guide 1, so that the light is gathered and emitted from the front end of the long light guide 1, thereby improving the brightness of the long light guide 1, and guiding the light emitted from the front end of the long light guide 1, so that more light can enter the light diffusion concave platform 21 and then light up the light guide plate 2, achieving the effect of multiplexing the light-emitting surface of the light guide plate 2;

[0024] The light guide plate 2 is an L-shaped bending structure, the vertical portion 221 of the light guide plate 2 extends along the height direction of the light guide support frame 11, the horizontal portion 222 of the light guide plate 2 is located above the light guide support frame 11, a plurality of the light diffusion concave platforms 21 are constructed on the vertical portion 221 of the light guide plate 2, and the light source corresponding to the light guide plate 2 is disposed toward the rear end of the horizontal portion 222 of the light guide plate 2;

[0025] The design of the horizontal portion 222 can make the light guide plate 2 and the long light guide 1 staggered in the light-emitting direction. Although the vertical portion 221 is far away from the light source corresponding to the light guide plate 2, it can be illuminated by two groups of light sources at the same time, so that the overall light guide plate 2 will not have too large a brightness difference.

[0026] It should be noted that the bending design of the L-shaped structure is only one implementation method in the present application. The length of the horizontal portion 222 can be reduced or eliminated according to the internal installation space of different vehicle models, and the light source can be directly set at the top of the vertical portion 221.

[0027] Specifically, the rear end of the long light guide 1 is a serrated surface 12, which increases the light output angle of the rear end of the long light guide 1, and cooperates with the inner wall of the light guide support frame 11 to achieve light reflection, so that the light emitted from the rear end of the long light guide 1 returns to the long light guide 1 again to illuminate the long light guide 1.

[0028] The light source is a PCB board 32 with LED lamp beads 31.

[0029] The working principle and working process of the utility model are as follows:

[0030] The long light guide 1 has a longer light shape continuity relative to the light guide plate 2, and can achieve a visual effect of penetrating lighting when lit. The vertically designed light guide plate 2 is spaced apart from the long light guide 1 and the vertical light emitting surface is also larger than the long light guide 1, so relative to the long light guide 1, a visual effect of suspended lighting can be achieved when lit. The combination of the two visual effects enables the entire lamp to achieve a three-dimensional lighting effect when in use.

[0031] The vertical portion 221 of the light guide plate 2 can also be illuminated by the long light guide 1 behind it, thereby achieving the effect of multiplexing the light-emitting surface of the light guide plate 2 .

[0032] The above embodiments of the utility model are described in detail, but the above contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of the utility model should still fall within the scope of this patent.
