Description

Technical Field

[0001] This utility model belongs to the field of headlight technology, specifically, it relates to a novel headlight light guide. Background Technology

[0002] Headlights are devices mounted on the front of a car and are mainly used for road lighting at night. With the advancement of technology, most headlights now rely on light guides for illumination, which are structural components that can guide the position of light.

[0003] A patent application (patent number 202021032092.9) published on December 1, 2020, discloses a light guide mounting structure for a headlight. The structure includes a light guide, a light guide bracket, and a lamp body. The light guide is mounted on the lamp body via the light guide bracket. A first end of the light guide is connected to a snap fastener, and a second end of the light guide forms a mounting head. The light guide bracket forms a light guide mounting groove. The lamp body forms a hook and a mounting head connecting portion. The light guide is disposed within the light guide mounting groove, which forms a top rib structure that cooperates with the light guide. The snap fastener connects to the hook, and the mounting head connects to the mounting head connecting portion. This headlight light guide mounting structure, while ensuring reliable installation, avoids the defects of light guide lighting, improves the optical efficiency of LEDs, saves production costs, and provides greater design flexibility, ultimately enhancing product competitiveness.

[0004] In the existing technology, the light guide cannot be turned due to the limitation of the headlight shape (the turning angle is less than 90 degrees), and due to the limitation of the shape, more light sources need to be arranged in order to ensure illumination, which increases the cost. Utility Model Content

[0005] The present invention aims to provide a new type of headlight guide that is simple to manufacture and has low cost.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a novel headlight guide, comprising a thick-walled component, a main light guide provided on the thick-walled component, and an irregularly shaped light guide for guiding light at the end of the thick-walled component, wherein the light guided by the irregularly shaped light guide and the main light guide illuminates the thick-walled component.

[0007] The thick-walled component is a structural feature for the signal area that needs to emit light.

[0008] The end of the main light guide is equipped with a light source.

[0009] The main optical guide is provided with bifurcated optical teeth.

[0010] The light source has two light-emitting points, and the light emitted by the light-emitting points is directed at the main light guide and the irregular light guide, respectively.

[0011] The irregularly shaped light guide is divided into an arc-shaped plate connected to the thick-walled component and an optical toothed plate disposed on the side of the arc-shaped plate.

[0012] The thick-walled component is J-shaped, and the main light guide and the irregularly shaped light guide are located at the bend of the thick-walled component.

[0013] The technical effect of this utility model is as follows: It adopts an irregularly shaped light guide to transmit a portion of the light to the area that needs to be illuminated, ensuring illumination while using multiple light guides to utilize only one light source, thus reducing the manufacturing cost of the headlight. At the same time, it adds a branch to the original light guide teeth and adds optical teeth to the main light guide to reflect the required light to the area that needs to be illuminated. By adjusting this optical tooth, the shape signal area that needs to be illuminated can be made to emit light. Attached Figure Description

[0015] The following are marked in the figure: 1. Thick-walled component; 2. Main light guide; 3. Irregular light guide; 31. Arc plate; 32. Optical tooth plate; 4. Light source; 5. Bifurcated optical tooth. Detailed Implementation

[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution, and to facilitate its implementation.

[0017] Please see Figure 1-3 A novel headlight guide includes a thick-walled component 1, a main light guide 2 on the thick-walled component 1, and an irregularly shaped light guide 3 at the end of the thick-walled component 1 to guide light. The light guided by the irregularly shaped light guide 3 and the main light guide 2 illuminates the thick-walled component 1. By using an irregularly shaped light guide, a portion of the light is transmitted to the area that needs to be illuminated, ensuring illumination while using multiple light guides to utilize only one light source 4, thus reducing the manufacturing cost of the headlight.

[0018] The thick-walled component 1 is a shaped signal area structure that needs to emit light; the light is guided to the thick-walled component 1 through the main light guide 2 and the irregular light guide 3 to emit light, so as to achieve the purpose of headlight illumination.

[0019] The end of the main light guide 2 is provided with a light source 4; the light source 4 is used to provide illumination.

[0020] The main light guide 2 is provided with a bifurcated optical tooth 5; a bifurcation is added to the original light guide tooth in the main light guide 2, and an optical tooth is added to the main light guide 2 to reflect the required light to the area that needs to emit light. By adjusting this optical tooth, the shape signal area that needs to emit light can be made to emit light.

[0021] The light source 4 has two light-emitting points, and the light emitted by the light-emitting points is directed at the main light guide 2 and the irregular light guide 3 respectively. The main light guide 2 is used for normal supplementary lighting, while the irregular light guide 3 is used for supplementary lighting. While ensuring the lighting effect, the requirements of the light source 4 are also reduced.

[0022] The irregularly shaped light guide 3 is divided into an arc-shaped plate 31 connected to the thick-walled member 1 and an optical toothed plate 32 disposed on the side of the arc-shaped plate 31; used to guide light to illuminate the thick-walled member 1.

[0023] The thick-walled component 1 is J-shaped, and the main light guide 2 and the irregular light guide 3 are set at the bend of the thick-walled component 1, so that the light rays drawn out by the main light guide 2 and the irregular light guide 3 can better cover the thick-walled component 1.

[0024] Working principle: The light emitted from the light source 4 enters the main light guide 2 and the irregular light guide 3 respectively. The light entering the main light guide 2 shines on the thick-walled component 1 through the light guide. At the same time, a branched optical tooth 5 is added to the light guide teeth on the main light guide 2, which can guide and reflect the light on the main light guide 2 to the area that needs to be illuminated, i.e., the thick-walled component 1. By adjusting this branched optical tooth 5, the shaped area that needs to be illuminated can be made to emit light, which can adapt to the shape of different headlight models. At the same time, the light source 4 can also shine light onto the irregular light guide 3, and transmit part of the light to the area that needs to be illuminated to achieve the effect of supplemental lighting. It achieves the effect of using an irregular light guide to transmit part of the light to the area that needs to be illuminated, ensuring illumination, while using multiple light guides and only using one light source 4, reducing the manufacturing cost of the headlight. At the same time, a branch is added to the original light guide teeth, and optical teeth are added to the main light guide 2 to reflect the required light to the area that needs to be illuminated. By adjusting this optical tooth, the shaped signal area that needs to be illuminated can be made to emit light.

[0025] The technical effect of this utility model is as follows: It adopts an irregularly shaped light guide to transmit a portion of the light to the area that needs to be illuminated, ensuring illumination. At the same time, by using multiple light guides, only one light source 4 is used, which reduces the manufacturing cost of the headlight. In addition, a branch is added to the original light guide teeth, and optical teeth are added to the main light guide 2 to reflect the required light to the area that needs to be illuminated. By adjusting this optical tooth, the shape signal area that needs to be illuminated can be made to emit light.

[0026] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
