[0029] See also Figures 1 to 4 In the specific embodiment shown, the utility model discloses an anti-glare downlight structure, comprising: a barrel 10, a COB lamp bead 20, a lens piece 30 and a reflective cup 40, the barrel 10 is provided with a accommodating cavity, a step is provided in the accommodating cavity so that the accommodating cavity forms an upper cavity and a lower cavity, the COB lamp bead 20 and the lens piece 30 are installed in the upper cavity, the reflective cup 40 is installed in the lower cavity, the reflective cup 40 is horn-shaped, and the light emitted by the COB lamp bead 20 passes through the lens piece 30 and is reflected by the reflective cup 40 and then emitted.
[0030] Specifically, glare refers to a visual condition that causes visual discomfort and reduces the visibility of objects due to inappropriate brightness distribution in the field of vision or extreme brightness contrast in space or time. Among them, the inner diameter of the upper cavity is smaller than the inner diameter of the lower cavity. This anti-glare downlight structure is provided with a step in the accommodating cavity so that the accommodating cavity forms an upper cavity and a lower cavity. The COB lamp bead 20 and the lens member 30 are installed in the upper cavity, and the reflective cup 40 is installed in the lower cavity. The reflective cup 40 is trumpet-shaped. The light emitted by the COB lamp bead 20 first passes through the lens member 30 and then is reflected by the reflective cup 40 and then emitted, so that the light can be evenly scattered, avoiding direct exposure to the human eye, thereby significantly reducing the glare phenomenon; in addition, due to the reduction of glare, this downlight can provide users with a more comfortable lighting environment. In scenes requiring concentrated lighting or local lighting, users will not feel discomfort or eye fatigue due to directly seeing the light source; in addition, in some cases, if people need to look up at the light source, such as checking the lamps on the ceiling, the direct light source will cause eye glare, making people feel uncomfortable. The design of this anti-glare downlight structure avoids this situation, so that people will not feel uncomfortable when looking up at the lamps. In addition, although the light is processed by the lens 30 and the reflective cup 40, this design does not affect the lighting efficiency of the light. On the contrary, due to the uniform scattering of the light, the lighting range is wider and the light distribution is more uniform, thereby improving the lighting efficiency.
[0031] In one embodiment, a concave cavity 31 is provided on the top of the lens member 30 , and the light-emitting surface of the COB lamp bead 20 faces the concave cavity 31 .
[0032] Specifically, the design of the concave cavity 31 enables the light-emitting surface of the COB lamp bead 20 to be more accurately oriented toward it, thereby ensuring that the light emitted by the COB lamp bead 20 can be received and transmitted by the lens member 30 more directly and effectively. This design can reduce the scattering and loss of light, and improve the utilization rate and lighting efficiency of light. In addition, by setting the concave cavity 31, the light emitted by the COB lamp bead 20 can be reflected and refracted multiple times inside the lens member 30, so that the light is more evenly distributed in the lighting area. This design helps to reduce light spots and dark areas and provide a more uniform and soft lighting effect. In addition, the design of the concave cavity 31 can adjust its size and shape as needed to further optimize the lighting effect. For example, by adjusting the depth and diameter of the concave cavity 31, the divergence angle and lighting range of the light can be controlled to meet the lighting needs in different scenes. In addition, since the light is evenly processed by the lens member 30, the light directly irradiated to the human eye is greatly reduced, thereby significantly reducing the glare phenomenon. This design makes people more comfortable when moving in the lighting area, reducing eye fatigue and discomfort.
[0033] In one embodiment, a COB bracket 50 is further provided on the top of the upper cavity, and the COB lamp bead 20 is connected to the COB bracket 50 .
[0034] Specifically, the COB bracket 50 is fixed to the cylinder 10 by screws, and the COB bracket 50 is used to fix the COB lamp bead 20. This fixing method can ensure that the COB lamp bead 20 is stably installed in the upper cavity to prevent it from shaking or displacement during operation, thereby ensuring the stable output of light and the durability of the lighting effect. In addition, by designing a special COB bracket 50 to fix the COB lamp bead 20, the installation process can be simplified and the installation efficiency can be improved. Compared with the traditional installation method, this design is more convenient and quick, and reduces the difficulty and cost of installation. In addition, the COB bracket 50 can also be made of a material with good thermal conductivity, or have a heat dissipation structure (such as heat dissipation holes, heat conductive sheets, etc.) to ensure that the COB lamp bead 20 can maintain a low temperature when working for a long time, thereby extending its service life.
[0035] In one embodiment, the lens element 30 is trumpet-shaped and translucent, and is made of acrylic material.
[0036] Specifically, the trumpet-shaped design helps the light to be reflected and refracted multiple times inside the lens 30, so that the light emitted by the COB lamp bead 20 can be more evenly distributed in the lighting area, reducing the appearance of light spots and dark areas. In addition, the trumpet-shaped structure has a beam expansion effect, that is, it can diffuse the light emitted by the COB lamp bead 20 to a wider area, thereby expanding the lighting range. In addition, the acrylic material has a high light transmittance, which means that most of the light can be transmitted through the lens 30, reducing the loss of light and improving the lighting efficiency.
[0037] In one embodiment, an annular protrusion 32 extends downward from the bottom of the lens member 30 , a circular opening is provided on the top of the reflective cup 40 , a groove 41 is provided outside the circular opening, and the annular protrusion 32 fits into the groove 41 .
[0038] Specifically, the annular protrusion 32 extending downward from the bottom of the lens member 30 is matched with the groove 41 outside the circular opening at the top of the reflector cup 40. This design ensures the precise positioning and stable fixation between the lens member 30 and the reflector cup 40. The matching relationship between the annular protrusion 32 and the groove 41 not only enables the two to fit tightly, but also, through the constraint of the groove 41, the lens member 30 is not easy to shift, thereby ensuring the stability and reliability of the entire lighting system. In addition, the matching of the annular protrusion 32 and the groove 41 not only achieves fixation and positioning, but also enhances the structural strength between the lens member 30 and the reflector cup 40. This design makes the connection between the two more secure and can withstand greater external impact or vibration, thereby improving the durability and service life of the entire lighting system. In addition, by ensuring the close fit between the lens member 30 and the reflector cup 40, the transmission loss of light between the two can be reduced, and the lighting efficiency can be improved. At the same time, this design also helps to optimize the distribution and diffusion of light, making the lighting more uniform and soft.
[0039] In one embodiment, the height of the reflective cup 40 is 25-35 mm, and the height of the lens element 30 is 15-22 mm.
[0040] Specifically, the height of the reflector 40 is designed to be within the range of 25-35 mm, which can ensure that the LED downlight has sufficient depth to effectively block the light source and reduce glare. The deeper reflector 40 helps to reflect the light to the area that needs to be illuminated, improves the lighting efficiency and reduces glare. The height of the lens 30 is designed to be 15-22 mm, which can ensure that enough light passes through the lens 30 for scattering and distribution, achieves uniform lighting, and maintains an appropriate anti-glare effect. In addition, the appropriate combination of the height of the reflector 40 and the height of the lens 30 can optimize the distribution and diffusion of light, making the lighting more uniform and soft, reducing the appearance of light spots and dark areas. This design helps to prevent light from directly irradiating the human eye and reducing the discomfort and visual fatigue caused by glare. In addition, by adjusting the height of the reflector 40 and the lens 30, different lighting needs and site characteristics can be adapted. For example, in a place where a higher lighting intensity is required, a higher height combination of the reflector 40 and the lens 30 can be selected, while in a place where soft lighting is required, a lower height combination can be selected.
[0041] In one embodiment, at least two connecting posts 42 are disposed on the back of the reflective cup 40 , and the cylinder 10 is provided with mounting positions 11 corresponding to the connecting posts 42 .
[0042] Specifically, the number of connecting columns 42 is 3, and they are evenly distributed, forming a stable triangular relationship, and the structure is more solid. The matching design of the connecting column 42 and the mounting position 11 ensures that the reflective cup 40 can be stably and accurately installed at the specified position of the cylinder 10. This design not only ensures the convenience during the installation process, but also ensures the stability and reliability after installation. In addition, through the design of at least two connecting columns 42, the reflective cup 40 can be fixed at multiple points on the cylinder 10, thereby preventing it from being displaced or shaken during use, ensuring the stability and consistency of the lighting effect. In addition, by ensuring the stable installation of the reflective cup 40, its role in reflecting light and improving the lighting effect can be maximized. At the same time, the stable installation also helps to reduce the noise and light spot problems caused by factors such as vibration, and improve the overall lighting performance.
[0043] In one embodiment, mounting components 60 are further provided on both sides of the cylinder 10, and the mounting components 60 include a connecting plate 61, a clamping plate 62 and a torsion spring 63. The connecting plate 61 is slidably connected to the cylinder 10, and the tops of the connecting plate 61 and the clamping plate 62 are hinged by a pin shaft. The torsion spring 63 is sleeved on the pin shaft, and one end of the torsion spring 63 is connected to the connecting plate 61, and the other end is connected to the clamping plate 62.
[0044] Specifically, the position of the connecting plate 61 on the cylinder 10 can be adjusted by sliding according to the installation requirements, and then the connecting plate 61 can be fastened to the cylinder 10 by screws. In addition, the installation assembly 60 is designed to be connected to the cylinder 10 by sliding, so that the entire assembly can flexibly adjust the position to adapt to different installation environments. This design greatly simplifies the process of installation and disassembly and improves work efficiency. In addition, the clamping plate 62 is hinged with the connecting plate 61 through a pin shaft, and the torsion spring 63 is sleeved on the pin shaft, one end of which is connected to the connecting plate 61, and the other end is connected to the clamping plate 62. This structure enables the clamping plate 62 to automatically clamp or release the external structure (for example, a wooden board) under the action of the torsion spring 63. This clamping method is stable and reliable, and can ensure a stable connection between the cylinder 10 and the external structure. In addition, the torsion spring 63, as a mechanical component that utilizes the elasticity and structural characteristics of the material, can provide an adaptive clamping force during the clamping process, which means that no matter how the size or shape of the external structure changes, the mounting assembly 60 can adapt through the elastic deformation of the torsion spring 63 and always maintain a stable clamping force. In addition, the design of the mounting assembly 60 not only takes into account the convenience of installation and the stability of clamping, but also takes into account the stability of the entire lighting system. Through the stable connection between the mounting assembly 60 on both sides and the external structure, the barrel 10 can be effectively prevented from shaking or tilting during use, ensuring the stability and reliability of the lighting effect. In addition, the design of this mounting assembly 60 has a wide range of applicability and can be applied to different installation environments and external structures. Whether it is a wall, a bracket or other forms of mounting points, as long as the clamping requirements of the mounting assembly 60 can be met, the barrel 10 can be easily installed stably.
[0045] In one embodiment, the cylinder 10 is further provided with a plurality of heat sinks 12 at intervals.
[0046] Specifically, the design of the heat sink 12 significantly increases the surface area of the cylinder 10, thereby increasing the contact area with the surrounding air, which helps to effectively transfer the heat generated inside the cylinder 10 to the external environment through thermal convection and thermal radiation, thereby achieving rapid heat dissipation. In addition, according to the principle of the heat sink 12, when heat is generated inside the cylinder 10, the heat will be transferred to the heat sink 12, and then transferred to the air or other media through the contact surface between the heat sink 12 and the surrounding environment. The presence of the heat sink 12 can greatly promote this process, thereby improving the heat dissipation efficiency. In addition, through the effective heat dissipation of the heat sink 12, the temperature of the cylinder 10 and its internal electrical components can be significantly reduced, avoiding problems such as performance degradation, accelerated aging, and even equipment damage caused by high temperature, which helps to maintain the stability and reliability of the equipment and extend its service life.
[0047] In one embodiment, the cylinder 10 is provided with a wire entry hole, and a wire pressing clamp 13 is provided on the outer side of the wire entry hole. The wire pressing clamp 13 is used for pulling the wires.
[0048] Specifically, the wire entry hole provided on the cylinder 10 allows the wire to pass through to be connected to the electrical components inside the cylinder. The wire clamp 13 is provided on the outside of the wire entry hole to ensure that the wire can be firmly fixed after passing through the wire entry hole, and prevent the wire from moving or getting loose due to external factors (such as wind force, human pulling, etc.). In addition, one of the main functions of the wire clamp 13 is to prevent the wire from being accidentally pulled. During the actual use of the power strip or other electrical equipment, the wire may be pulled for various reasons. Without the protection of the wire clamp 13, the wire may slip out of the wire entry hole or be pulled off, causing the equipment to be powered off or damaged. The wire clamp 13 can ensure that the wire will not slip or be damaged when subjected to a certain range of tension through its tightening effect.
[0049] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
