[0003] like Figure 1 The diagram shows the structure of a star ring headlight in the prior art, which includes a housing, a mask, and a rubber band. Since the star ring headlight is mounted on the hood, the rubber band can only be placed on the outer surface, and the rubber band is transparent, which leads to light leakage. Furthermore, since the rubber band is integrally molded and adheres to the inner wall of the mask, the tension of the rubber band will leave stress marks on the inner wall of the mask. To address these issues, the applicant has designed a light fixture to prevent light leakage. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a lamp structure that prevents light leakage. It is designed with segmented and opaque rubber strips to avoid the problems of light leakage and stress marks left on the inner wall of the lamp cover.

[0006] A light-leakage-proof lamp structure includes: a housing, a mask fixedly connected to the housing, and a light source and a reflector disposed within the cavity formed by the housing and the mask, wherein the light emission direction of the light source passes through the reflector;

[0007] The mask and the outer shell are fixedly installed in sections with non-transparent first and second parting adhesive strips at the connection points to prevent the light from the light source from being exposed along the connection points between the mask and the outer shell.

[0008] Furthermore, both the first and second parting adhesive strips are black.

[0009] Furthermore, the second parting adhesive band further includes a light-emitting port, which is inserted through and fitted onto the mask.

[0010] Furthermore, the reflector has a reflector body, and the light from the light source is reflected to the light outlet through the reflector body.

[0011] Furthermore, the main body of the reflector is a Fresnel lens.

[0012] Furthermore, the outer shell includes a housing, and the housing has a first connection and a second connection on both sides, with the feet of the first parting rubber band and the second parting rubber band fixedly installed in the grooves of the first connection and the second connection.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, the segmented rubber bands are made opaque to prevent light from leaking out from both sides. In addition, the segmented rubber bands are placed in the thicker part of the mask. Since they are not integrally molded, they will not cause stress marks on the mask due to tension. At the same time, the dual effects of preventing light leakage and eliminating stress marks are achieved. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides a technical solution: a light-leakage-proof lamp structure, which can prevent the light leakage problem of the lamp and solve the stress marks caused by the integrated setting of the rubber band on the mask.

[0022] It should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", and "rear" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0023] like Figure 2 As shown, the present application provides a light leakage prevention lamp structure, including a housing 1, a mask 4 fixedly connected to the housing 1, a light source 6 disposed in the cavity formed between the housing 1 and the mask 4, the light source 6 being fixedly mounted on the housing 1, a reflector 2 disposed along the light emission direction of the light source 6, and a first parting adhesive rib 52 and a second parting adhesive rib 53 being fixedly installed in sections between the connection points of the mask 4 and the two ends of the housing 1. The first parting adhesive rib 52 and the second parting adhesive rib 53 are opaque. The light emitted by the light source 6 will be reflected by the reflector 2 into the cavity formed by the housing 1 and the mask 4, while the first parting adhesive rib 52 and the second parting adhesive rib 53 can prevent light from leaking out along the gap between the mask 4 and the housing 1, thus solving the light leakage problem of the lamp.

[0024] contrast Figure 1 The lamp structure shown also includes a rubber band 3, which is a one-piece design. Since the upper end of the rubber band 3 is attached to the inner wall of the faceplate 4, and because this lamp structure is a ring lamp, it is mounted on the cover. Due to the mounting position, the one-piece structure of the rubber band 3 will leave stress marks on the faceplate 4. Figure 2 The segmented first parting adhesive strip 52 and second parting adhesive strip 53 shown are only set at the gap connecting the mask 4 and the outer shell 1. The thickness of the part of the mask 4 without adhesive strips is increased to maintain the original thickness. Due to the parting design and the installation position of the first parting adhesive strip 52 and second parting adhesive strip 53 in the thicker part of the mask 4, stress marks will not be left on the inner wall of the mask 4 due to tension issues, thus solving the problem of stress marks on the mask 4.

[0025] Furthermore, since the first parting adhesive strip 52 and the second parting adhesive strip 53 are black, the light emitted by the light source 6 will be blocked by the first parting adhesive strip 52 and the second parting adhesive strip 53 after being reflected by the reflector 2 and passing through the connection between the mask 4 and the outer shell 1.

[0026] Furthermore, the second parting adhesive band 53 also includes a light outlet 51, which penetrates the mask 4 and is fitted onto the mask 4, allowing light to pass through.

[0027] Furthermore, such as Figure 2 As shown, the reflector 2 has a reflector body 201, which is a Fresnel lens or other lens that can reflect the light emitted by the light source 6. The reflector body 201 faces the light outlet of the light source 6. The light is reflected and diffused by the reflector body 201 into the cavity formed by the mask 4 and the outer shell 1, and finally exits along the light outlet 51, thus forming a light distribution as shown in the image. Figure 3 The lighting effect is in the shape of a star ring.

[0028] Furthermore, such as Figure 2 As shown, the outer shell 1 includes a shell 11. The two sides of the shell 11 also have a first connection 12 and a second connection 13 corresponding to the first parting adhesive 52 and the second parting adhesive 53. The first connection 12 and the second connection 13 are recessed inward to form a groove. The first parting adhesive 52 and the second parting adhesive 53 have feet that can be snapped into the grooves of the connection to form a fixed connection.

[0029] The above provides a detailed description of the light-leakage-proof lamp structure provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model.
