[0002] In the process of producing car lights, in the existing scheme, after the light is emitted from the LED, it passes through a series of action devices and then exits from the light-emitting surface, so as to achieve a more uniform lighting effect of the car lights. Among them, the reflective thick-walled parts scheme adopts aluminum plating more often, which is mainly composed of thick-walled parts and reflectors. A light outlet is formed at one end of the thick-walled parts, and a light incident surface is formed at the other end of the thick-walled parts. The reflector is arranged opposite to the light incident surface. After the reflector reflects the light to the light incident surface, it passes through the thick-walled parts and then exits from the light outlet. Since the reflector reflects the light to the light incident surface, it first passes through the air and then enters the thick-walled parts, so the light will be refracted. However, considering the assembly between the parts, the reflective thick-walled parts usually have protruding mounting ribs on the upper and lower sides. Due to the action of the mounting ribs, part of the light incident on the light incident surface is blocked by the mounting ribs and cannot be reflected to the light outlet, thus causing a dark area phenomenon and uneven lighting. In order to solve this problem, a thick-walled part structure that improves the dark area when viewed from above is proposed. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The thick-walled member structure for improving the dark area in top view according to an embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-Figure 4As shown, according to the embodiment of the utility model, the structure of the thick-walled component for improving the dark area when looking down comprises: a thick-walled component 1 and a reflector 2; a light emitting surface 11 is formed at one end of the thick-walled component 1, and a light incident surface 12 is formed at the other end of the thick-walled component 1, the light emitting surface 11 and the light incident surface 12 are arranged opposite to each other, the reflector 2 and the thick-walled component 1 are connected by a connecting plate 3, the reflector 2 and the light incident surface 12 are arranged opposite to each other, the light incident surface 12 is an inclined surface, and the angle between the light incident surface 12 and the connecting plate 3 is greater than 90 degrees, and the reflector 2 is used to collimate the light and inject the light into the thick-walled component 1.

[0029] In this embodiment, in order to avoid blocking the light reflected by the reflector 2, the connecting plate 3 is protruded from the lower surface of the thick-walled member 1, and the area where the connecting plate 3 and the thick-walled member 1 are connected is the mounting rib 4. After the light enters the reflector 2, the reflector 2 reflects the collimated light to the light incident surface 12. At this time, since the light enters the medium from the air, the light is refracted when entering the light incident surface 12. The refracted light is reflected in the thick-walled member 1, and a part of the light is totally reflected to the light exiting surface 11 to complete the light exiting. The other part of the light passes through the mounting rib 4, so Part of the light passing through here leaks out from the thick-walled part 1, and total reflection cannot be achieved, resulting in a darker brightness of the reflected light in this part; since the light incident surface 12 is set in an inclined state, the mounting rib 4 is moved backward so that the light passing through the mounting rib 4 does not correspond to the area where the light emitting surface 11 is located after reflection, so that the area in the thick-walled part 1 that can achieve total reflection satisfies the luminous area of ​​the light emitting surface 11, avoiding the phenomenon of dark areas on the light emitting surface 11, so as to ensure the uniformity of the light on the light emitting surface 11; the thick-walled part structure with improved dark areas when viewed from above is integrally formed to facilitate production.

[0030] The light incident surface 12 is composed of a plurality of steps, each of which is composed of a refractive surface 121 and a connecting surface 122 . The refractive surface 121 is used to receive the light reflected by the reflector 2 .

[0031] In this embodiment, by setting multiple steps, the inclined light incident surface 12 is divided into multiple small parts to facilitate adjustment of the angle of the refractive surface 121 so that the angle of the refractive surface 121 is the same as the angle of the light incident surface 12 before tilting, thereby ensuring that the angle at which the light incident surface 12 receives light remains unchanged.

[0032] The light emitting surface 11 is a corn grain pattern, which diffuses the light to improve the lighting uniformity.

[0033] The length and width of the refractive surface 121 are consistent with the length and width of the cross section of the corn kernel pattern, so that the light emitted from the refractive surface 121 can correspond to the corn kernel on the light emitting surface 11 to maximize the light propagation efficiency.

[0034] The refractive surface 121 is provided with patterns to improve the uniformity of light diffusion of the refractive surface 121 .

[0035] There are two connecting surfaces 122. The two connecting surfaces 122 on a step are arranged adjacent to each other. The two connecting surfaces 122 are connected to the refractive surface 121 on the same step. The angle formed between the two connecting surfaces 122 and the refractive surface 121 is 83-97 degrees. Preferably, the angle formed between the two connecting surfaces 122 and the refractive surface 121 is 90 degrees. The multiple refractive surfaces 121 are all parallel. The connecting surfaces 122 are used to connect adjacent refractive surfaces 121, so that the collimated light emitted by the reflector 2 can be vertically incident on the refractive surface 121 without passing through the connecting surfaces 122, thereby improving the light propagation efficiency.

[0036] The reflector 2 is an aluminum-plated surface to increase the light diffusion efficiency and improve the lighting uniformity.

[0037] The inner surface of the connecting plate 3 is a stripe-shaped pattern, so as to reflect the light reflected by the reflector 2 and passing through the connecting plate 3 to the light incident surface 12, so as to reduce the loss of light.

[0038] The thick-walled member 1 is made of transparent material, such as PMMA or PC.

[0039] 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.

[0040] 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.
