Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting fixtures, specifically to a light leakage prevention lighting fixture. Background Technology

[0002] The "star ring light" on the headlights mainly refers to a continuous LED light strip that surrounds the front or rear of the vehicle. It can present a dynamic lighting effect, significantly improving the vehicle's recognizability and sense of technology. The star ring light uses multiple LED light sources and achieves uniform light emission and dynamic flowing effect through special processes such as thick-wall injection molding.

[0003] Automotive lights need to be equipped with light shields so that light can be emitted from the areas that need to emit light, while the areas that do not need to emit light are blocked by the light shields to prevent light leakage and other problems. In addition, the lights will deform during later use, and the gaps created by the deformed lights can cause light leakage. Therefore, the applicant proposes a light leakage prevention light fixture to solve the above problems.

[0004] The information disclosed in the background section is only intended to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to design a light-leakage-proof lamp, which has a higher strength rubber rib assembly inside the lamp for light blocking, and also has a deformable light-blocking component that deforms along with the product to ensure that no light leaks out at all times, thereby solving the above-mentioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A light-leakage-proof lamp includes a housing and a faceplate fixedly connected to each other. A light-emitting element is also fixedly installed along the inner wall of the housing. A reflective element is provided along the light-emitting direction of the light-emitting element. A light-emitting area is provided on the faceplate in the direction of the light reflected by the reflective element.

[0008] The inner wall of the mask is fitted with a rubber band assembly for blocking light. The rubber band assembly is an integrally formed structure. The rubber band assembly includes a mask rubber band that is fitted to the inner wall of the mask. The bottom of the mask rubber band is integrally provided with a first rubber band foot and a second rubber band foot, which are fixedly inserted into the shell.

[0009] A deformable light-shielding element is also provided at the angle between the mask rubber band and the first rubber band foot, and the light-shielding element deforms as the lamp deforms.

[0010] Furthermore, the light-shielding component is made of expanded foam or hollow adhesive.

[0011] Furthermore, the light-shielding component is circular, and its two sides are respectively fixedly adhered to the inner wall of the mask's adhesive band and the inner wall of the first adhesive band foot.

[0012] Furthermore, the housing includes two sets of fixedly connected first and second outer shells, with slots respectively provided on the first and second outer shells for the first and second rubber reinforcing feet.

[0013] Furthermore, the light-emitting area includes a light-emitting port formed on the mask, and the adhesive assembly further includes a light-emitting component, which is fitted into the light-emitting port.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] This utility model features an integrated rubber reinforcement assembly, which provides excellent strength and prevents bending or breakage when the lamp is deformed. In addition, a deformable light-shielding component is also provided on the rubber reinforcement assembly, which can deform along with the lamp when it is deformed, thereby achieving better light-shielding.

[0021] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] This utility model provides, for example Figure 1-2 The light-leakage prevention lamp shown includes a housing and a cover 1 that are fixedly connected to each other. A light-emitting element 6 is also fixedly installed on the inner wall of the housing. A reflector 5 is also provided along the light-emitting direction of the light-emitting element 6. A light-emitting area is also provided on the cover 1 so that the light emitted by the light-emitting element 6 can be reflected by the reflector 5 and then emitted through the light-emitting area to form a star ring light of a car headlight.

[0024] To prevent light leakage from the lamp, a light-shielding adhesive rib assembly 3 is provided in the cavity formed by the housing and the mask 1. The adhesive rib assembly 3 includes a mask adhesive rib 31 that is attached to the inner wall of the mask 1 to block the light leakage area of ​​the mask 1. The bottom of the mask adhesive rib 31 is also provided with a first adhesive rib foot 32 and a second adhesive rib foot 33. The first adhesive rib foot 32 and the second adhesive rib foot 33 are fixedly inserted into the housing to block the light leakage areas on both sides. In this way, the adhesive rib assembly 3 forms a shield to cover the light-emitting element 6 and prevent light from leaking out.

[0025] Among them, such as Figure 2 As shown, the rubber band assembly 3 is a one-piece structure, which gives it good compressive strength and reduces molding processes. This also prevents breakage when the lamp deforms. Furthermore, a deformable light-shielding member 4 is provided at the angle between the faceplate rubber band 31 and the first rubber band foot 32. This light-shielding member 4 deforms along with the lamp, providing synchronized light blocking. Further, as... Figure 1-2 As shown, the light-shielding component 4 can be expanding foam, hollow glue, or other deformable colloids, which can play the role of deformation and light blocking. The two sides of the light-shielding component 4 are respectively fixedly bonded to the inner walls of the mask glue rib 31 and the first glue rib foot 32. Only one set of light-shielding component 4 is provided. Since there is usually a light-shielding glue strip between the lamp and the front cover, but no light-shielding glue strip is provided at the other end, the deformable light-shielding component 4 needs to be provided at the end of the lamp that is not connected to the front cover.

[0026] Furthermore, such as Figure 2 As shown, the light-emitting area includes a light-emitting port 11 opened on the mask 1, and the adhesive band assembly 3 further includes a light-emitting element 34, which is fitted into the light-emitting port 11.

[0027] Furthermore, such as Figure 1As shown, the housing also includes two mutually fixedly connected first outer shell 2 and second outer shell 21. The two outer shells are spliced ​​together to form a housing that is fixedly connected to the upper mask 1. Slots are also provided at corresponding positions of the first outer shell 2 and the second outer shell 21, so that the first rubber band foot 32 and the second rubber band foot 33 can be fixedly inserted into the slots on the two outer shells, so that the rubber band assembly 3 and the two outer shells are fixedly connected, forming a shield for the light-emitting element 6 set on the housing to block the light.

[0028] In use, the light from the light-emitting element 6 is emitted along the direction of the reflector 5 and reflected by the reflector 5 onto the light-emitting element 34. The light-emitting element 34 allows light to pass through. The light-emitting element 34 is a ring-shaped strip, so the light on the light-emitting element 34 forms a star ring lamp. Since the integrated rubber band assembly 3 forms a shield for the light-emitting element 6, it can prevent light leakage and other problems. In addition, if the lamp is deformed later, the light shield 4 has the ability to deform and can deform along with it, thereby playing the role of preventing light leakage.

[0029] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape and proportion of various elements, as well as parameter values ​​(e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application.
