Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to an LED ceiling light assembly with an anti-glare structure. Background Technology

[0002] With the popularization of LED lighting technology, LED ceiling lights are widely used in homes, offices, commercial spaces, and other fields. However, traditional LED ceiling lights often neglect glare control in their design, easily producing dazzling direct light that causes visual fatigue and affects the lighting experience.

[0003] While some existing luminaires employ diffusers or frosted covers to reduce light intensity, they still struggle to fundamentally solve the glare problem, especially when the light source is exposed or the illumination uniformity is poor. Therefore, it is necessary to propose an LED ceiling light structure with anti-glare functionality to improve user visual comfort and meet the demands for high-quality lighting. Utility Model Content

[0004] The purpose of this invention is to provide an LED ceiling light assembly with an anti-glare structure, which can effectively suppress direct light, reduce glare, and improve the uniformity of illumination.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an LED ceiling light assembly with an anti-glare structure, comprising a lamp body, a light source assembly, and an anti-glare cover. The lamp body is provided with a reflective cavity, which is composed of a concave structure and has a high reflectivity coating on its inner surface. The light source assembly is fixedly installed at the center of the bottom of the reflective cavity. The anti-glare cover is disposed at the light outlet of the lamp body, and the inner surface of the anti-glare cover is provided with several light-guiding micro-prism structures or diffusion patterns, which are matched with the light outlet direction of the reflective cavity to refract and uniformly diffuse light.

[0006] Preferably, the anti-glare cover has an arc-shaped structure and is injection molded from a frosted material to further soften the light.

[0007] Preferably, the edge of the reflective cavity is provided with a slot, and the anti-glare cover is snapped into the slot for easy assembly and maintenance.

[0008] Preferably, the lamp body has ventilation holes on its side wall and is covered with a dustproof net to improve the heat dissipation performance of the lamp body and prevent dust from entering.

[0009] Preferably, the light source assembly is a ring-shaped LED module with its radiation direction facing the inner wall of the reflective cavity to avoid glare through indirect light emission. Attached Figure Description

[0016] Example 1: As Figures 1-5 As shown, an LED ceiling light assembly with an anti-glare structure includes a lamp body 1, a light source assembly 2, and an anti-glare cover 3. A concave reflective cavity 4 is formed inside the lamp body 1, and the inner wall of the reflective cavity 4 is coated with a high-reflectivity silver-white coating to improve light utilization.

[0017] [0016A] Preferably, the reflective cavity 4 is a bowl-shaped concave structure, and its inner wall is formed with a silver reflective coating by physical vapor deposition, with a reflectivity of not less than 90%, which is used to reflect the light emitted by the light source component 2 from multiple angles and converge it to the anti-glare cover 3.

[0018] [0016B] The light-guiding micro-prism structure 9 of the anti-glare cover 3 is arranged in strip-shaped micro-prisms in an interlaced distribution with a spacing of 0.2-0.5mm. It is used to achieve the refraction and diffusion of light, making the light output more uniform, significantly reducing the glare index (UGR), and improving lighting comfort.

[0019] The light source component 2 is a ring-shaped LED module, which is installed on the bottom central axis of the reflective cavity 4. The emitted light shines towards the inner wall of the reflective cavity 4 and propagates to the light outlet of the lamp body after multiple reflections.

[0020] The anti-glare cover 3 is set at the light outlet of the lamp body 1 and is installed in the slot 5 provided on the edge of the reflective cavity 4 by snap-fit. The anti-glare cover 3 is made of frosted PC material by injection molding and has annular diffusion micro-textures 6 on the surface, which effectively reduces glare.

[0021] Multiple ventilation holes 7 are opened on the side wall of the lamp body 1 and covered with a dustproof net 8 to improve the internal heat dissipation performance and prevent dust from entering the lamp cavity and affecting the life of the light source.

[0022] Example 2: Several staggered micro-ridge structures 9 are formed on the inner surface of the anti-glare cover 3. This structure can guide light to refract multiple times, achieve a soft light effect, and significantly improve the comfort of lighting.

[0023] Example 3: The driving power supply of the light source component 2 is located in an independent chamber on the back of the lamp body 1, which is separated from the thermal zone of the light source cavity, which is beneficial to the heat dissipation of electronic components and improves stability.

[0024] Example 4: Positioning protrusions 10 are provided on the edge of the anti-glare cover 3, which are correspondingly engaged in the limiting holes of the lamp body 1. The position can be automatically calibrated during the installation process, improving the assembly efficiency.

[0025] Example 5: A certain gap is formed between the anti-glare cover 3 and the reflective cavity 4. Combined with the arc surface design, the light is uniformly reflected inside the cover, resulting in a softer output and avoiding hot spot concentration.
