[0025] The following further describes the present utility model in detail with reference to the drawings.

[0026] Combined with the attached Figure 1 to the attached Figure 5 A high - light - efficiency anti - glare LED cultural and creative downlight, comprising a lamp body housing 1. Inside the lamp body housing 1, an LED light source assembly 2 is fixedly provided. The LED light source assembly 2 includes a circuit board 21 and a plurality of LED lamp beads 22 evenly distributed on the circuit board 21. Inside the lamp body housing 1 and above the LED light source assembly 2, an anti - glare lens 3 is provided. The anti - glare lens 3 is hemispherical. The light - emitting surface of the anti - glare lens 3 has a microstructure optical texture. The microstructure optical texture includes a number of annular protrusions 31 and depressions 32 distributed at intervals. The geometric center area of the anti - glare lens 3 is a light diffusion area 33, and the light diffusion area 33 contains light diffusion particles.

[0027] In this embodiment, as a preferred technical solution, the lamp body housing 1 is of a cylindrical structure, and a plurality of heat - dissipation areas 4 are fixedly provided on its side surface. A number of heat - dissipation fins 5 are fixedly provided on the surface of the heat - dissipation areas 4.

[0028] In this embodiment, as a preferred technical solution, the anti - glare lens 3 is installed inside the lamp body housing 1 through a fixed frame 6. The fixed frame 6 is tightly connected to the inner wall of the lamp body housing 1. The material of the anti - glare lens 3 is optical - grade transparent plastic or glass, and the refractive index is between 1.4 and 1.6.

[0029] In this embodiment, as a preferred technical solution, the thickness of the light diffusion region 33 is greater than that of the edge region. The thickness of the light diffusion region 33 is 1.2 - 1.5 times that of the edge region. The particle size of the light diffusion particles is between 1 - 5 microns, and the light diffusion particles are made of inorganic materials such as titanium dioxide or barium sulfate.

[0030] The working principle of a high - light - efficiency anti - glare LED cultural and creative downlight of the present utility model is as follows: When the high - light - efficiency anti - glare LED cultural and creative downlight starts to work, the LED light source assembly 2 located inside the lamp body housing 1 is powered on, and multiple LED lamp beads 22 on the circuit board 21 emit light. The light emitted by the LED lamp beads 22 first shines on the anti - glare lens 3 located above. The anti - glare lens 3 is hemispherical, and the micro - structure optical texture on its light - emitting surface starts to function. The annular protrusions 31 and depressions 32 refract and scatter the light, changing the propagation direction of the light. At the same time, the light diffusion region 33 contains light diffusion particles made of inorganic materials such as titanium dioxide or barium sulfate, and the particle size of these particles is between 1 - 5 microns. Since the refractive index of the light diffusion particles is different from that of the lens main body material, the light is scattered when passing through the light diffusion particles, making the originally concentrated light disperse more evenly. The thickness of the light diffusion region 33 is greater than that of the edge region, and the thickness is 1.2 - 1.5 times that of the edge region. This special thickness design provides more opportunities for the interaction between the light and the light diffusion particles, further enhancing the anti - glare effect.

[0031] When the LED lamp beads 22 emit light and work, a large amount of heat is generated. Multiple heat dissipation regions 4 on the side of the lamp body housing 1 start to function. A number of heat dissipation fins 5 are fixedly arranged on the surface of the heat dissipation regions 4. These heat dissipation fins 5 increase the contact area with the air and can quickly conduct the heat inside the lamp body to the air, thereby effectively reducing the temperature of the lamp body.

[0032] The above describes the present utility model and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the creative purpose of the present utility model, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
