Description

Technical Field

[0001] The utility model relates to the technical field of linear lamps, in particular to a light-shielding end cover of a linear lamp. Background Art

[0002] In the linear light market, the aluminum profile in linear light fixtures is the main part of the fixture, which is generally divided into two cavities, the upper and lower cavities. The lower cavity is the light trough for installing the light-emitting components and the diffuser mounting trough for installing the diffuser. The light trough is generally installed with reflective paper on both sides. To comply with safety regulations, end caps are required at both ends of the linear light to prevent light leakage and provide safety protection. The end caps currently on the market have the following problems:

[0003] 1. Because the aluminum profile of the main part of the lamp has a rough cutting surface during the early cutting process, and the end covers on the market are all flat, there will be a slight gap between the profile cutting surface and the end cover after assembly. When the lamp is powered on, the two ends of the light-emitting groove cannot be completely shielded from light, and light will leak out from the slight gap between the end cover and the profile, affecting the customer's experience of using the product.

[0004] 2. Soft plastic or foam is generally used to fill the profile cut to reduce the gap between the end cover and the profile cut. However, this structure has to go through complicated steps during use, which is inefficient and time-consuming and labor-intensive. In addition, when soft plastic and foam are used for filling and after long-term use, uncertainty in the direction and amount of extrusion deformation may occur, which is not conducive to the secondary disassembly and assembly of the lamp in the later maintenance. The luminous surface will be affected by the soft plastic or foam and there will be shadows, which will also affect the lighting effect and the perception of use of the lamp.

[0005] 3. Currently, end caps can only be matched according to the color of the lamp surface. For example, when the outer surface of the lamp is black, the end cap color is black, which has a strong light absorption effect. When the outer surface of the lamp is white, the matching end cap color is white, which has a weak light absorption effect. In addition, some materials may have severe light transmission. Therefore, the light-shielding effect of ordinary end caps will be indirectly affected by the end caps that match the color of the lamp outer surface. Summary of the Invention

[0006] In order to solve certain technical problems existing in the prior art, the purpose of this application is to provide a linear lamp shading end cover, which can not only solve the light leakage problem caused by the assembly of the end cover and the lamp, but also solve the problem of complex installation process of the end cover and the lamp. The subsequent maintenance of the lamp is convenient, and after disassembling and assembling the end cover, there will be no indirect impact due to material problems, thereby fundamentally solving the light leakage problem.

[0007] To solve the above existing technical problems, this application adopts the following technical solutions:

[0008] A light-shielding end cap for a linear lamp comprises an end cap body. An inwardly protruding light-shielding lining is provided on the inner side of the end cap body, and both ends of a light-emitting groove of a lamp profile are light-shielded by the light-shielding lining.

[0009] Preferably, an inwardly protruding embedding boss is further provided on the inner side of the end cover body, and the embedding boss is inserted into the light-emitting groove of the lamp profile.

[0010] Preferably, the shading lining is a trapezoidal structure, and an inclined slot is formed between the shading lining and the embedded boss, and the end of the reflective paper in the linear light is inserted into the slot.

[0011] Preferably, the embedding boss is provided with a guide piece that is inclined outward and protrudes, and the reflective paper to be inserted into the slot is guided and slid in by the guide piece.

[0012] Preferably, a snap-fit ​​structure is provided between the light-shielding lining and the end cover body, and the light-shielding lining is detachably arranged in the end cover body through the snap-fit ​​structure.

[0013] Preferably, the snap-fit ​​structure includes a limiting groove and a snap-fit ​​groove provided on the light-shielding lining, and a limiting block and a snap buckle provided on the end cover body.

[0014] Preferably, the bottom of the end cover body is further provided with a baffle protruding into the diffuser plate mounting groove of the lamp profile.

[0015] Preferably, the baffle is arranged at an angle, and one side of the baffle extends under the installed diffuser plate.

[0016] Preferably, the color series of the light-shielding lining is black.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The inner profile of the end cover body is provided with a shading lining that protrudes into the lamp profile, so that both ends of the light-emitting groove of the lamp profile can be specifically shielded by the shading lining. When blocking the light, the shading can be achieved only by the raised structure inside the combination of the end cover body and the shading lining, combined with reflective paper. The operation is very simple, and there is no need to add additional materials to the surface of the lamp to apply in the light-leaking gaps. It is not affected by the extrusion deformation of the material when it is first used and after long-term use.

[0024] Below, the present application is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

Therefore, they should not be understood as limitations on this application.

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0027] like Figure 1 and Figure 4 As shown, a light-shielding end cover of a linear lamp comprises an end cover body 1 , the inner side of the end cover body 1 is provided with a light-shielding lining 3 protruding inward, and both ends of the light-emitting groove 12 of the lamp profile 13 are shaded by the light-shielding lining 3 .

[0028] In actual use, in addition to the light-emitting components, linear lights generally include lamp profiles 13, end cover bodies 1, and reflective paper and other structures. Among them, during the light-emitting process of the light-emitting components, the conventional end covers at both ends of the lamp profile 13 are prone to light leakage, and after adding soft plastic or foam cotton for filling, various process and maintenance problems are also prone to occur. Therefore, in order to better prevent light from leaking out from the end of the end cover body 1, a shading lining 3 is protruded into the lamp profile 13 on the inner profile of the end cover body 1, so that the two ends of the light-emitting groove 12 of the lamp profile 13 are targetedly shielded by the shading lining 3. When blocking the light, shading can be achieved only by the raised structure inside the combination of the end cover body 1 and the shading lining 3, combined with reflective paper. The operation is very simple, and there is no need to add additional materials to the surface of the lamp to apply in the light-leaking gaps. It is not affected by the extrusion deformation of the material when it is first used and after long-term use. The stability of the shading can be guaranteed even when it is repeatedly disassembled and assembled. The overall size of the shading end cover is small and the weight is light. When assembled with the lamp, the operation is convenient and quick.

[0029] As a further improvement, an inwardly protruding embedding boss 6 is further provided on the inner side of the end cover body 1 , and the embedding boss 6 is inserted into the light emitting groove 12 of the lamp profile 13 .

[0030] The embedded boss 6 not only positions the connection between the lamp profile 13 and the end cap body 1, but also seals and shields the gap between them, effectively preventing light from escaping through the gap and eliminating the need for additional soft plastic or foam. Furthermore, the entire end cap body 1 is unaffected by the extrusion deformation that occurs during initial use and over time, ensuring stable light shielding even after repeated assembly and disassembly.

[0031] A further improvement is that the light-shielding lining 3 is a trapezoidal structure, an inclined slot 5 is formed between the light-shielding lining 3 and the embedded boss 6, and the end of the reflective paper is inserted into the slot 5.

[0032] The shading lining 3 is a trapezoidal structure. The combination of the trapezoidal shading lining 3 and the embedded boss 6 can form an inclined slot 5, thereby facilitating the insertion of the end of the reflective paper in an inclined state into the slot 5. The insertion of the reflective paper compensates for the problem of light leakage in the areas at both ends of the reflective paper.

[0033] As a further improvement, a guide piece 2 that is inclined outward and protrudes is provided on the embedding boss 6, and the reflective paper to be inserted into the slot 5 is guided and slid in by the guide piece 2.

[0034] Since the slot 5 is relatively narrow and the reflective paper is in sheet form, it is easy for the embedded boss 6 on the inner side of the end cap to press against the reflective paper during installation, causing the reflective paper to deform. Therefore, to ensure that the reflective paper can be quickly inserted into the slot 5, a guide piece 2 with an outwardly inclined protrusion is formed on the embedded boss 6. During assembly, the reflective paper to be inserted into the slot 5 can be guided by the guide piece 2 and slide in quickly, thereby avoiding the situation where the reflective paper is difficult to insert into the slot 5.

[0035] Further improvement is as follows: Figure 2 and Figure 3 As shown, a snap-fit ​​structure is provided between the light-shielding lining 3 and the end cover body 1 , and the light-shielding lining 3 is detachably arranged in the end cover body 1 through the snap-fit ​​structure.

[0036] The shading lining 3 is detachably mounted in the end cover body 1 through a snap-fit ​​structure. The snap-fit ​​structure allows the shading lining 3 to be quickly assembled without any tools, thus completing the initial assembly of the assembly and reducing installation time.

[0037] As a further improvement, the snap-fit ​​structure includes a limiting groove 7 and a snap-fit ​​groove 10 provided on the light-shielding lining 3 , and a limiting block 9 and a snap 8 provided on the end cover body 1 .

[0038] When assembling the shading lining 3 and the end cover body 1 through the snap-fit ​​structure, it is only necessary to align the limit groove 7 with the limit block 9, and then press the shading lining 3 to the end cover body 1, so that the bayonet can automatically snap into the slot 10 to achieve connection. When disassembly is required, it is only necessary to push the shading lining 3 outward to achieve separation. The overall disassembly and assembly is more convenient and simple, and the operation difficulty is lower. Disassembly and assembly can be achieved without the aid of tools during operation.

[0039] As a further improvement, the bottom of the end cover body 1 is further provided with a baffle 4 protruding into the diffuser plate installation groove 11 of the lamp profile 13; the baffle 4 is arranged at an angle, and one side of the baffle 4 extends under the installed diffuser plate.

[0040] Since there will be a certain gap between the diffuser plate and the end cover body 1 after the diffuser plate is installed, which will cause light leakage problems, therefore, a raised baffle 4 is formed at the bottom of the end cover body 1 by bending into the diffuser plate mounting groove 11 of the lamp profile 13. The baffle 4 can better compensate for the gap and achieve better shading effect, especially when the baffle 4 is inclined. After the diffuser plate is installed, one side of the baffle 4 extends into the bottom of the diffuser plate through the inclined surface, so that a cross-stacked assembly is formed between the end of the diffuser plate and the baffle 4, thereby achieving a sealing effect and preventing light from leaking out.

[0041] A further improvement is that the color series of the light-shielding lining 3 is black.

[0042] The shading lining 3 is an independent accessory. The shading lining 3 is made of a relatively hard material and adopts a black lining. It can be universally adapted to the end covers of lamps of different colors, and always has the effect of shading and absorbing reflected light, thereby making the shading effect of the end cover more stable and more adaptable.

[0043] The above-mentioned embodiments are only preferred embodiments of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and replacements made by technicians in this field based on the present application shall fall within the scope of protection required by the present application.
