[0002] With the rapid progress of LED lighting technology and the continuous improvement of consumers' requirements for quality of life, track floodlights, as an important part of modern lighting, are increasingly widely used. From commercial spaces to home environments, they all demonstrate their unique lighting charm. However, while pursuing efficient lighting effects, how to balance optical performance and user experience has become a key issue that the industry needs to solve urgently.

[0003] In order to ensure good anti-glare effect and uniform light distribution, the traditional track floodlight design usually requires the integration of multiple components inside the lamp. These components are assembled through the preset slots of the shell, which can effectively achieve double or even multiple anti-glare, improve the UGR value and optimize the lighting experience. However, it also brings a side effect that cannot be ignored - the problem of abnormal noise caused by the assembly gap. The existence of the gap not only affects the overall aesthetics of the product, but also causes the internal components to shake and generate noise when subjected to external forces, which seriously reduces the user's comfort and satisfaction, thereby weakening the market competitiveness of the product.

[0027] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be described in detail below with reference to the attached drawings and specific embodiments.

[0028] Here, it should be noted that in order to avoid obscuring the present utility model due to unnecessary details, only the structures and / or processing steps closely related to the solution of the present utility model are shown in the attached drawings, while other details less related to the present utility model are omitted.

[0029] In addition, it should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0030] Please refer to Figures 1 to 6As shown, an embodiment of the utility model provides a lighting fixture 100, including: a housing 1 and two end caps 5 respectively disposed at both ends of the housing 1 along the length direction. The two end caps 5 are respectively used to close both ends of the housing 1. The lighting fixture 100 can be lighting products such as track lights and linear lights.

[0031] The housing 1 includes a side wall 13 extending along the length direction and a top wall 14 disposed above the side wall 13. The top wall 14 and the side wall 13 enclose a receiving cavity 11 extending along the length direction.

[0032] A partition is provided in the receiving cavity 11 to divide the receiving cavity 11 into upper and lower cavities. The light source 6 and the power supply 7 are respectively installed in different cavities, and the light source 6 is fixed on the partition. Generally, the power supply 7 is installed in the upper cavity, and the light source 6 is installed in the lower cavity. The power supply 7 is used to supply power to the light source 6. The light source 6 is generally a light source board, and the light source board is used to emit light. An outlet 12 is provided at the bottom of the cavity where the light source 6 is installed, and the light emitted by the light source 6 is emitted from the outlet 12.

[0033] Please refer to Figure 3 As shown, the side wall 13 is provided with a first abutting portion 131 and a second abutting portion 132 that extend along the length direction and are arranged in sequence along the height direction. The first abutting portion 131 and the second abutting portion 132 are prisms or long columns. Among them, the first abutting portion 131 is disposed close to the outlet 12, and an installation space is formed between the first abutting portion 131 and the second abutting portion 132.

[0034] An anti-glare film 4, a prism plate 3 and a panel 2 are sequentially arranged in the installation space along the height. The anti-glare film 4 can effectively suppress reflected light and scattered light, reduce glare phenomenon, and improve visual comfort. The prism plate 3 can further adjust the distribution of light, ensure that the light is irradiated evenly and softly, and improve the overall lighting effect and visual quality. The panel 2 is generally made of a high-transparency material, such as acrylic plate and transparent plate, etc. The high-transparency panel 2 not only ensures a high light transmittance, enables the light to propagate unobstructed, but also adds a sense of transparency to the lighting fixture 100.

[0035] Please refer to Figures 3 to 4 As shown, the first abutting portion 131 includes a pressing surface 1311 facing the panel 2 and an inclined guiding surface 1312 opposite to the pressing surface 1311. The first abutting portion 131 can stably abut against the panel 2 through the pressing surface. Thus, the first abutting portion 131 can bear part of the weight of the panel 2, distribute the weight load reasonably, and enhance the structural stability of the entire lighting fixture 100.

[0036] The inclined guiding surface 1312 includes a highest point and a lowest point arranged along the height direction. From the lowest point to the highest point, the light outlet 12 is in the shape of a gradually expanding flared opening, which can increase the light-emitting range and improve the overall light-emitting efficiency. With such a setting, when light rays are emitted from the light source 6 and pass through this structure, they can propagate along the gradually expanding flared path, achieving effective guiding of the light rays.

[0037] Please refer to Figures 5 to 6 As shown, the panel 2 is arranged in the accommodation cavity 11 and is close to the light outlet 12. The prism plate 3 is arranged on the side of the panel 2 facing away from the light outlet 12. The anti-glare film 4 is arranged on the side of the prism plate 3 facing away from the panel 2. In the length direction, the anti-glare film 4 includes a covering section 42 having the same length as the prism plate 3 and an extending section 41 extending beyond the prism plate 3.

[0038] During the installation process of the end cap 5, the end cap 5 will squeeze the anti-glare film 4. The anti-glare film 4 has good ductility, and the external force extrusion will cause the anti-glare film 4 to deform and gradually fill the gap between the prism plate 3 and the end cap 5. When the installation of the end cap 5 is completed, at this time, the anti-glare film 4 wraps the prism plate 3 in a shape like the Chinese character "ji". Due to the anti-glare film 4 being squeezed by the end cap 5, it will closely adhere to the prism plate 3 and fill the gap between the prism plate 3 and the end cap 5, making the structure compact and effectively eliminating the abnormal noise that may be generated due to the assembly gap. Since the anti-glare film 4 can fill the gap, it reduces the shaking or loosening caused by the assembly gap, ensuring the stability and reliability of the internal components of the lamp 100 during long-term use.

[0039] The end cap 5 is press-fitted and connected to the panel 2, and the projection shape of the press-fitting surface of the end cap 5 and the anti-glare film 4 on the side surface of the housing 1 is in the shape of the Chinese character "chang". The end cap 5 closes the accommodation cavity 11 in the length direction, which not only achieves structural stability but also has a dust-proof function. The anti-glare film 4 is deformed by extrusion, resulting in at least part of the extending section 41 being located between the end cap 5 and the panel 2. Filling the gap between the panel 2 and the end cap 5 makes the panel 2 and the end cap 5 closely adhere to each other, preventing the panel 2 from shaking in the length direction and generating abnormal noise.

[0040] In this embodiment, the lamp 100 squeezes the anti-glare film 4 with good ductility through the end cap 5, and the anti-glare film 4 deforms to fill the gap between the prism plate 3 and the panel 2, tightly adhering the prism plate 3 and the panel 2 together, making the structure of the lamp 100 compact. The anti-glare film 4 is provided with an extending section 41, and the extending section 41 fills the gap between the prism plate 3 and the panel 2 and the end cap 5. Since the anti-glare film 4 eliminates the space for the prism plate 3 and the panel 2 to shake in the housing 1, it effectively prevents the prism plate 3 and the panel 2 from shaking in the housing 1 and even generating abnormal noise.

[0041] Please refer to Figure 5As shown, the extension section 41 includes a first section 411 and a second section 412. The end cap 5 includes a first joint surface 51, a second joint surface 52, and a third joint surface 53. The first joint surface 51 abuts against the end of the panel 2 arranged in the length direction, so that the panel 2 and the end cap 5 are tightly assembled. The first section 411 is clamped between the second joint surface 52 and the panel 2 in the height direction, and the first section 411 can fill the gap between the panel 2 and the second joint surface 52. The second section 412 is clamped between the prism plate 3 and the third joint surface 53 in the length direction, and the second section 412 can fill the gap between the prism plate 3 and the third joint surface 53.

[0042] Please refer to Figure 5 As shown, a chamfer 54 is provided at the connection between the second joint surface 52 and the third joint surface 53. Since the chamfer 54 can effectively buffer the impact force generated during the assembly of the end cap 5, effectively reduce the impact force on the anti-glare film 4, and thus protect the anti-glare film 4.

[0043] Preferably, there is a gap between the second abutting portion 132 and the third joint surface 53, which reserves sufficient space for the extrusion deformation of the anti-glare film 4 during the assembly process. In addition, the reserved gap also avoids unnecessary interference between the anti-glare film 4 and other parts of the housing 1 or the end cap 5 during the assembly process.

[0044] In the height direction, there is a first distance between the second joint surface 52 and the pressing surface 1311. For the convenience of assembly, the thickness of the panel 2 is often less than the first distance. The panel 2 does not abut against the pressing surface 1311. There is a certain height difference between the panel 2 and the pressing surface 1311, and the panel 2 has a space where it can shake in the height direction. In this embodiment, the anti-glare film 4 is extruded by the end cap 5, so that the sum of the thickness of the panel 2 and the thickness of the anti-glare film 4 is equal to the first distance. That is to say, the anti-glare film 4 fills the gap between the panel 2 and the pressing surface 1311, eliminating the possibility of the panel 2 shaking in the height direction, and thus avoiding the abnormal noise generated by the shaking.

[0045] In order to minimize the installation gap, it is defined that in the length direction, the prism plate 3 has a first length, the panel 2 has a second length, and the anti-glare film 4 has a third length. The second length is greater than the first length, and the third length is greater than or equal to the second length. Such a setting ensures that the anti-glare film 4 has enough length to fill the possible gaps generated during the assembly process. Minimize problems such as shaking and abnormal noise caused by the assembly gap, and improve the assembly accuracy and overall stability of the lamp 100.

[0046] Preferably, in the height direction, the thickness of the prism plate 3 is defined as a. In the length direction, the length of the prism plate 3 is defined as c. The length of the pressing surface of each end cap 5 and the panel 2 is b. The value range of the length L of the anti-glare film 4 is c + 2a + b < L ≤ c + 2a + 2b. This range is the preferred range. Setting this range facilitates the placement of the anti-glare film 4. By abutting one end against the inner side of the end cap 5, the other end can extend out after the prism plate 3 is placed, which is convenient for the positioning and installation of the anti-glare film 4. With such a setting, the anti-glare film 4 can fill the gaps between the prism plate 3, the panel 2 and the end cap 5, and can also fill the gap between the panel 2 and the pressing surface 1311.

[0047] In summary, for the lamp 100 of the present invention, the end cap 5 presses the anti-glare film 4, causing the extension section 41 of the anti-glare film 4 to deform, ensuring that at least part of the extension section is located between the end cap 5 and the panel 2. Furthermore, the extension section 41 fills the gaps between the prism plate 3, the panel 2 and the end cap 5, making the panel 2, the prism plate 3 and the anti-glare film 4 fit tightly together, forming a structurally compact whole, effectively reducing the assembly gap of the lamp 100. In addition, the extension section 41 fills the gaps between the prism plate 3, the panel 2 and the end cap 5, playing a limiting role on the prism plate 3 and the panel 2. It effectively avoids the situation where the prism plate 3 and the panel 2 can shake under external forces, and also avoids the abnormal noise problem that may occur when the panel 2 and the prism plate 3 shake in the housing 1.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
