Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, and in particular to a highly adaptable LED lighting module. Background Technology

[0002] LED modules generally consist of LED beads, chips, lamp holders, and related circuitry. Due to their high brightness, low energy consumption, and long lifespan, they are widely used in various lighting scenarios. However, in practical applications, because they are point light sources with strong directional light, they can easily produce high brightness contrast, leading to glare problems. This can cause discomfort such as glare and eye strain for users, resulting in a poor user experience. To solve the glare problem, anti-glare covers are usually equipped, using light blocking, diffusion, or guiding technologies to optimize light distribution, reduce direct glare, and improve visual comfort.

[0003] However, the existing LED lighting design has the following defects: 1. Limited adaptability: Different lighting environments have different requirements for anti-glare effect. For example, shopping malls, offices and exhibition halls may need anti-glare covers with different transmittance or angles. However, the LED lighting fixtures on the market are usually LED lights corresponding to one type of anti-glare cover, which is difficult to meet the needs of multiple application scenarios; 2. High production cost: Since the power module of the lamp holder in the existing LED module is usually assembled by a separate bottom cover, and then assembled with the housing containing LED chips, lenses and other modules; there are many parts, and it is difficult to adapt to anti-glare covers of various specifications, which increases the material and labor costs; (3) Inconvenient installation: The traditional anti-glare cover is mostly installed by screw fixing, and the assembly process is complicated and requires professional tools to operate.

[0004] Therefore, it is necessary to propose a new type of highly adaptable LED lighting module to solve the problems existing in the above-mentioned prior art. Utility Model Content

[0033] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings and embodiments. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0034] like Figure 1-8 As shown, this embodiment 1 provides a highly adaptable LED lighting module, including a lamp holder 1 and a power module 2, a heat sink 3, an LED chip 4, and a lens 5 installed inside the lamp holder 1. The upper end of the lamp holder 1 is provided with a light outlet 11. The heat sink 3 is adapted to be installed on the inner wall of the lamp holder 1 near the light outlet 11, and its outer wall is press-fitted with the inner wall of the lamp holder 1. The inner side of the lamp holder 1 is provided with a structure or step for fixing the heat sink 3, which will not be described in detail. The LED chip 4 is attached to the heat sink 3. The lens 5 is covered at the light outlet 11. The power module 2 is fixed at the end of the lamp holder 1 away from the light outlet 11, and the inner wall of the lamp holder 1 is provided with a through hole 12 for an external wire A to pass through and form an electrical connection with the power module 2. Specifically, the through hole 12 can be provided in the middle part of the bottom of the lamp holder 1, or it can be provided in the side wall part of the lamp holder 1.

[0035] The lamp holder 1 is provided with an anti-glare cover 6 at one end near the light outlet 11. The inner wall of the lamp holder 1 is provided with a mounting part 13 for the anti-glare cover 6. The end of the anti-glare cover 6 near the lamp holder 1 is screwed into the inner side of the mounting part 13.

[0036] Specifically, in this embodiment, the lamp holder 1 is a ceramic lamp holder 1 made of alumina ceramic; the lamp holder 1 has a plurality of heat dissipation strips 13 on its outer periphery; the heat dissipation cup 3 is an aluminum heat dissipation cup 3, and the outer periphery of the side wall of the heat dissipation cup 3 is provided with a plurality of heat dissipation channels 32 at intervals. Utilizing the high thermal conductivity of aluminum, the concentrated heat of the LED chip 4 is dissipated, reducing the heat flux density, and uniformly and quickly conducted to the lamp holder 1, accelerating the heat exchange between the lamp holder 1 and the outside air to achieve a better heat dissipation effect. Furthermore, utilizing the high thermal radiation characteristics and excellent insulation properties of ceramic, the heat dissipation capacity of this composite heat dissipation structure is further improved while ensuring insulation.

[0037] In this embodiment, the light-emitting function of the LED chip 4, the electrical connection relationship required to achieve light emission, and the electrical function of the power supply module 2 all refer to the prior art. This utility model only improves its assembly structure and does not involve improvements to the light-emitting or power supply module 2's electrical functions. Therefore, the above-mentioned electrical and circuit aspects will not be described in detail. The working principle of the lens 5 and the specific way it covers the lamp holder 1 will also not be described in detail.

[0038] In one embodiment, the anti-glare shield 6 has a swivel groove 61 extending obliquely along its circumference at its end, and a limiting member 14 that can slide along the swivel groove 61 is provided on the inner wall 13 of the mounting part; in another embodiment, the mounting part has a swivel groove 61 extending obliquely along its circumference at its inner wall, and a limiting member 14 that can slide along the swivel groove 61 at its end; the swivel groove 61 has an opening for the limiting member 14 to enter the swivel groove 61, and a limiting slot 611 is provided at the end of the swivel groove 61 away from the opening, and the limiting member 14 slides along the swivel groove 61 into the limiting slot 611 and is limited therein. The advantage of this design is that a standardized installation structure is used to achieve a stable installation of the anti-glare shield 6;

[0039] Meanwhile, the structure of the anti-glare shield 6 is further improved: in one embodiment, the anti-glare shield 6 includes an assembly column 62 and an anti-glare reflector cup 63; the anti-glare reflector cup 63 is provided with an anti-glare channel on its inner side, and the cross-section of the anti-glare channel is gradually widened in the direction away from the light outlet 11; the assembly column 62 and the anti-glare reflector cup 63 are integrally formed, and the assembly column 62 is screwed into the inner side of the mounting part.

[0040] In another embodiment, the anti-glare shield 6 includes an assembly post 62 and an anti-glare reflector 63; the assembly post 62 is screwed into the inner side of the mounting part, and its outer wall is provided with an outwardly extending limiting post 621; the side wall of the anti-glare reflector 63 is provided with a limiting hole 631 that matches the limiting post 621; the anti-glare reflector 63 is fixedly mounted on the assembly post 62 by the insertion of the limiting post 621 and the limiting hole 631; the inner side of the anti-glare reflector 63 is provided with an anti-glare channel, and the cross-section of the anti-glare channel is gradually widened in the direction away from the light outlet 11.

[0041] In this way, the improved mounting structure of the anti-glare cover 6 is adapted to the mounting part of the LED module, allowing a single LED module to be replaced with different types of anti-glare covers 6 according to different application scenarios without changing the structure of the lamp holder 1, which greatly improves the adaptability and application flexibility of the LED module.

[0042] Further details regarding the installation structure of the anti-glare shield 6: The outer wall of the mounting column 62 is provided with a circumferentially extending guide ramp 622, causing the width of the engagement groove 61 to gradually narrow from the opening towards the limiting slot 611. More specifically, the guide ramp 622 is provided with an elastic reinforcement 64. The limiting member 14 slides along the engagement groove 61, passes the elastic reinforcement 64, and then slides into the limiting slot 611 and is limited. This design, by providing a circumferentially extending guide ramp 622 on the outer wall of the mounting column 62, gradually narrows the width of the engagement groove 61, guiding the limiting member 14 into the limiting slot 611, achieving precise positioning. The elastic reinforcement 64 on the guide ramp 622 gradually applies pressure during the sliding of the limiting member 14, making it increasingly tighter and forming a stable locking effect, preventing loosening or detachment. Meanwhile, the limiting component 14 is interference-fitted when it enters the limiting slot 611, which further enhances the installation firmness of the anti-glare cover 6 and improves the assembly stability and durability.

[0043] Further refining the design, the inner wall of the lamp holder 1 is radially recessed to form a stepped mounting portion; a gap exists between the limiting member 14 and the bottom surface of the mounting portion, which is the same height as the limit groove 611 to the end of the outer wall of the anti-glare shield 6; the limiting member 14 is located in the limit groove 611, and the end of the outer wall of the mounting post 62 abuts against the bottom surface of the mounting portion. Thus, by forming a stepped mounting portion through the radial recess of the inner wall of the lamp holder 1, and maintaining a specific gap between the limiting member 14 and the bottom surface of the mounting portion, which corresponds precisely to the height from the limit groove 611 to the end of the outer wall of the anti-glare shield 6, when the limiting member 14 slides into the limit groove 611, the end of the outer wall of the mounting post 62 abuts against the bottom surface of the mounting portion, thereby creating a double limiting effect.

[0044] The fixing of the LED chip 4 is further described. The LED chip 4 is fixed at the center of the heat sink 3 by clamping screws 7. The bottom plate of the heat sink 3 is provided with screw holes for installing the clamping screws 7 at two opposite corners of the LED chip 4. The two clamping screws 7 are respectively installed in the screw holes and clamp the LED chip 4.

[0045] Furthermore, the base plate of the heat sink 3 is provided with limiting protrusions 31 at the edge of the LED chip 4; at least two limiting protrusions 31 are distributed at intervals at opposite ends of the LED chip 4 to limit the displacement of the LED chip 4. The screw hole is offset from the limiting protrusions 31.

[0046] In this embodiment, the portion where the LED chip 4 is assembled with the heat sink 3 has a square structure. Two limiting protrusions 31 are distributed on opposite sides of this square structure, while two clamping screws 7 are clamped and fixed at their opposite corners, offset from the limiting protrusions 31. This ensures stable installation of the LED chip 4. In other embodiments, four or more limiting protrusions 31 may be provided.

[0047] This invention allows anti-glare covers 6 of different specifications to share the same LED module, reducing the lighting configuration requirements for different scenarios, thereby reducing material and inventory costs, while optimizing production and installation efficiency. Furthermore, the screw-on installation method makes replacing the anti-glare cover 6 more convenient, allowing for quick assembly without the need for specialized tools, further improving production and assembly efficiency. Moreover, the integrated lamp holder 1 structure is optimized, with the power module 2 directly integrated and installed at the bottom of the lamp holder 1, eliminating the need for an additional bottom cover. Internal through-holes 12 provide pre-drilled wiring paths. This also reduces the number of components, eliminating the need for additional wiring or the addition of the power module 2, reducing installation steps, avoiding poor contact, and improving the stability of electrical connections.

[0048] The above embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of protection of the present utility model. For those skilled in the art, it will be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
