[0020] In the description of the present application, it should be pointed out that the directions or positional relationships indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like are based on the positional relationship shown in the drawings, and are only for the convenience of describing the present application, and do not indicate that the device must have a specific orientation or be operated in a specific orientation, therefore it cannot be understood as a limitation on the present application.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments, and are not intended to limit the present application.

[0022] The present application will be described in detail below with reference to the drawings and embodiments.

[0023] A spotlight cover, as shown in Figure 1 and Figure 2 , comprising a lamp shell 1, a light condensing sheet 2 and a lamp bulb 3, a cavity 4 for accommodating the lamp bulb 3 is formed in the lamp shell 1, the light condensing sheet 2 is detachably connected to the lamp shell 1, two symmetrical mounting interfaces 12 are arranged at the bottom of the lamp shell 1, the light condensing sheet 2 is detachably connected, so that the user or the maintenance personnel can easily replace the damaged light condensing sheet 2 without replacing the whole lamp cover, reducing the maintenance cost, and also facilitating the operator to open the light condensing sheet 2 to adjust and replace the position of the electronic components inside the lamp shell 1, so that the lighting effect is better during use, the two symmetrical mounting interfaces 12 can ensure that the lamp cover is more stable during installation, avoid loosening or damage caused by uneven stress, and make it easier to align and fix during installation.

[0024] Specifically, the top surface and the bottom surface of the light-converging sheet 2 are respectively provided with a light-converging groove 5 and an inclined ridge 6. The light-converging groove 5 is located directly above the bulb 3, and the inclined ridge 6 is arranged in a ring shape and along the circumferential direction of the light-converging groove 5. The thickness of the inclined ridge 6 is less than the thickness of the light-converging sheet 2. Through the above arrangement, the inclined ridge 6 can better guide and concentrate light during use of the bulb 3, reduce light loss, and improve light-converging efficiency. The ring-shaped arrangement of the inclined ridge 6 can enhance the overall stability of the light-converging sheet 2 and prevent deformation caused by external force or thermal expansion. The thickness of the inclined ridge 6 is less than the thickness of the light-converging sheet 2, which can reduce the overall weight of the light-converging sheet 2 while ensuring structural strength, facilitate installation and use, and reduce the space occupied by the inclined ridge 6 in the cavity 4, thereby avoiding contact and collision between the bulb 3 or other electronic components. In addition, the light-converging groove 5 can increase the friction between the light-converging sheet 2 and the fingers of the operator, thereby preventing the light-converging sheet 2 from falling.

[0025] Further, the inclined ridge 6 is provided with four groups, and the four groups of inclined ridges 6 are arranged in an array along the circumferential direction of the light-converging groove 5. The inclined ridge 6 is provided with an inclined surface one 7 and an inclined surface two 8, and the inclination of the inclined surface one 7 is greater than that of the inclined surface two 8. The four groups of inclined ridges 6 are arranged in an array along the circumferential direction, which can perform multi-stage reflection and refraction on light, making the light more uniformly distributed when passing through the light-converging sheet 2. Since the inclination of the inclined surface one 7 is greater than that of the inclined surface two 8, it can more accurately control the focusing direction and intensity of the light, reduce light scattering, and improve light-converging effect. Through multi-stage guidance, light can be more efficiently concentrated in the target area, reducing light loss caused by uneven reflection or refraction.

[0026] The top surface of the light-converging sheet 2 is a plane, the depth of the light-converging groove 5 is less than 1 / 3 of the thickness of the light-converging sheet 2, and a plurality of arc-shaped protrusions 9 are arranged in the light-converging groove 5. The arc-shaped protrusions 9 can have a light-converging effect. Since the depth of the light-converging groove 5 is less than 1 / 3 of the thickness of the light-converging sheet 2, the overall structural strength of the light-converging sheet 2 is ensured.

[0027] The outer edge of the light-converging sheet 2 is provided with a limiting ring 10, and the inner wall of the lamp shell 1 is provided with a limiting groove 11 for accommodating the limiting ring 10. The light-converging sheet 2 is embedded in the limiting groove 11 through the limiting ring 10 to realize relative rotation with the lamp shell 1. Through the design of the limiting ring 10 and the limiting groove 11, the connection between the light-converging sheet 2 and the lamp shell 1 is more stable, and the light-converging sheet 2 can be quickly installed and removed, simplifying the assembly and maintenance process and reducing the operation difficulty. When the limiting ring 10 is embedded in the limiting groove 11, the position of the light-converging sheet 2 can be accurately fixed, avoiding light deviation caused by improper installation.

[0028] Further, the limiting ring 10 and the limiting groove 11 are provided with a magnetic locking mechanism, the magnetic locking mechanism comprises a permanent magnet ring 16 arranged at the bottom of the limiting ring 10 and a magnetic conducting ring 17 embedded in the limiting groove 11, the magnetic conducting ring 17 is provided with a positioning recess 18 corresponding to the magnetic pole of the permanent magnet ring 16 in the circumferential direction, the permanent magnet ring 16 and the magnetic conducting ring 17 are automatically positioned by magnetic pole attraction, when the spotlight sheet 2 rotates to a preset angle, the positioning recess 18 of the permanent magnet ring 16 and the magnetic conducting ring 17 generates adsorption force due to the matching of the magnetic poles, thereby achieving the effect of accurate positioning and rapid locking, at the same time, the magnetic attraction force of the permanent magnet ring 16 and the magnetic conducting ring 17 can offset the displacement caused by equipment vibration or accidental collision, thereby achieving the effect of preventing loosening, the outer wall of the lamp shell 1 is provided with a heat dissipation fin 13, the heat dissipation fin 13 is provided with an axially extending flow guide groove 14, and the bottom of the lamp shell 1 is provided with a heat dissipation hole group 15 communicating with the accommodating cavity 4, the heat dissipation hole group 15 is composed of strip-shaped holes arranged in a radial manner, by arranging the heat dissipation fin 13, the surface area of the outer wall of the shell body is increased, and heat is diffused to the air at a faster speed, and the flow guide groove 14 extends in the axial direction of the lamp shell 1, forming a directional airflow channel, thereby improving the heat dissipation efficiency of the spotlight.

[0029] The inner wall of the lamp shell 1 is coated with a reflective coating, the reflective coating is an aluminum-based coating or a white ceramic coating with high reflectivity, and the bottom surface of the spotlight sheet 2 is provided with a heat insulation layer, which is a high-efficiency heat insulation nano coating, both the aluminum-based coating and the white ceramic coating have extremely high reflectivity, can efficiently reflect light, reduce light loss, thereby significantly improving the condensing effect, can ensure that the reflection of light on the inner wall of the lamp shell 1 is more uniform and efficient, and enhance the illumination intensity and uniformity, and the high-efficiency heat insulation nano coating on the bottom surface of the spotlight sheet 2 can effectively block heat transfer, protect the spotlight sheet 2 from high temperature, prevent the spotlight sheet 2 from deforming or being damaged due to high temperature, and prolong the service life thereof.
