Description

Technical Field

[0001] The utility model belongs to the technical field of thick-walled parts, and in particular relates to a thick-walled part structure for a vehicle lamp. Background Art

[0002] With the rapid development of automobile lighting technology, there are more and more shapes. In recent years, LEDs are increasingly used in automobile lighting. In existing solutions, the direction of light is changed by a reflector to achieve the desired light output effect. However, the reflector is not transparent and cannot meet the user's visual needs for automobile lighting. In addition, in order to achieve the reflection effect, aluminum plating is required on the reflector, which leads to high process costs. In order to improve the visual transparency, a thick-walled structure of automobile lighting is proposed. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art.

[0004] To this end, the utility model proposes a thick-walled structure of a vehicle lamp, which has the advantages of ensuring light efficiency while improving visual transparency.

[0005] According to the thick-walled structure of a vehicle lamp in an embodiment of the utility model, the structure includes: a main body, which is transparent, and a reflective surface is formed at one end of the main body, and the reflective surface is a parabola with a focus, and the other end of the main body is a light emitting surface, and the light emitting surface is located in the light emitting direction of the reflective surface, and the light source is installed on the focus of the reflective surface.

[0006] According to an embodiment of the utility model, a plurality of reflective patterns are formed on the reflective surface, and the reflective pattern is a parabola with a focus, and the light reflected by the plurality of reflective patterns forms a plurality of diamond-shaped light spots.

[0007] According to an embodiment of the present invention, the focus of the reflective pattern and the focus of the reflective surface are co-pointed.

[0008] According to an embodiment of the utility model, the reflective pattern is recessed in the main body to save the size of the main body.

[0009] According to an embodiment of the utility model, a diffusion pattern is formed on the light emitting surface to increase the light emitting area.

[0010] According to an embodiment of the utility model, the diffusion pattern is a corn kernel pattern or a water ripple pattern.

[0011] According to an embodiment of the utility model, a light incident end is formed on the main body to change the incident angle of the light incident on the reflective surface, so that the light is totally reflected after passing through the reflective surface.

[0012] According to an embodiment of the present invention, the light incident end is located on the upper surface of the main body.

[0013] According to an embodiment of the present invention, the main body, the reflective pattern and the diffusion pattern are integrally formed.

[0014] The beneficial effect of the utility model is that the reflective surface is set as a parabola with a focus, so that when the light source arranged at the focus of the reflective surface emits light to the reflective surface, the light is reflected by the reflective surface and then emitted horizontally, so that the reflected light is emitted through the light emitting surface. In this process, the disorderly emission direction of the light, which causes some light to be unable to pass through the light emitting surface, is avoided, thereby improving the utilization rate of the light and meeting the demand for lighting effect. At the same time, since the main body is transparent, the visual transparency is improved.

In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The thick-walled component structure of a vehicle lamp according to an embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-Figure 3 As shown, the thick-walled structure of the vehicle lamp according to the embodiment of the utility model includes: a main body 1, the main body 1 is transparent, a reflective surface 2 is formed at one end of the main body 1, the reflective surface 2 is a parabola with a focus, the other end of the main body 1 is a light emitting surface 3, the light emitting surface 3 is located in the light emitting direction of the reflective surface 2, and the light source is installed on the focus of the reflective surface 2.

[0028] In this embodiment, the light source is arranged at the focus of the reflective surface 2, so that the light emitted by the light source is reflected by the reflective surface 2 and then emitted horizontally, so that the reflected light is emitted through the light emitting surface 3. In this process, the disorderly emission direction of the light is avoided, which causes part of the light to be unable to pass through the light emitting surface 3, thereby improving the utilization rate of the light and meeting the demand for lighting effect. At the same time, since the main body 1 is transparent, the visual transparency is improved.

[0029] A plurality of reflective patterns 5 are formed on the reflective surface 2 . The reflective pattern 5 is a parabola with a focus. Light reflected by the plurality of reflective patterns 5 forms a plurality of diamond-shaped light spots.

[0030] In this embodiment, the reflective pattern 5 may be a parabola that forms a diamond-shaped light spot after reflection, or a plurality of reflective patterns 5 may form a parabola that forms a diamond-shaped light spot after reflection, so as to further improve the light effect through the diamond-shaped light spot.

[0031] The focus of the reflective pattern 5 is at the same point as the focus of the reflective surface 2, that is, the reflective pattern 5 and the reflective surface 2 share a focus. When the light source emits light to the reflective surface 2, the light emission directions of multiple reflective patterns 5 are consistent to ensure full utilization of light.

[0032] The reflective pattern 5 is recessed in the main body 1 to save the size of the main body 1 .

[0033] A diffusion pattern is formed on the light emitting surface 3 to increase the light emitting area. The diffusion pattern includes but is not limited to corn kernel patterns or water ripples. When the reflective pattern 5 reflects light to the light emitting surface 3, the light emitting area is increased after being diffused by the diffusion pattern.

[0034] A light input end 4 is formed on the main body 1, and the light input end 4 is located on the upper surface of the main body 1, the reflecting surface 2 is located on the left side of the main body 1, and the light output surface 3 is located on the right side of the main body 1. The light input end 4 is a hemispherical groove formed on the upper surface of the main body 1. The light source is installed above the light input end 4. After the light source emits light to the light input end 4, the light is refracted by the light input end 4, which changes the incident angle of the light to the reflecting surface 2, so that the light is totally reflected after passing through the reflecting surface 2, so as to improve the utilization rate of the light. The light source is arranged above the light input end 4 to avoid blocking the light reflected by the reflecting surface 2 and ensure the utilization rate of the light.

[0035] The main body 1, the reflective pattern 5 and the diffusion pattern are integrally formed. The main body 1, the reflective pattern 5 and the diffusion pattern can be injection molded to reduce production steps, reduce production difficulty, save production costs, avoid subsequent assembly, and make the positions of the reflective pattern 5 and the diffusion pattern on the main body 1 more precise. At the same time, it saves installation steps, saves the space required for installation, and reduces the size requirement for the main body 1.

[0036] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0037] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
