For example, as shown in CN202021343179.8, the light from the light source plate shines outward from the lampshade. However, due to the structural limitations of the lampshade, the light from the edge of the light source plate shines outward from the periphery of the lampshade, resulting in some wasted light, affecting the lighting effect, and limiting its applicability.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] See Figures 1 to 5 As shown, a double-sided lens industrial lamp structure includes a heat sink 1, a light source plate 2 fixed on the heat sink, and a lens cover 3. In this embodiment, the heat sink and the light source plate are conventional structures of the prior art, and are simply applied, so they are not described in detail. The heat sink is circular, elliptical, or rectangular; the shape of the lens cover matches the shape of the heat sink.

[0028] In this embodiment, the lens cover includes a lens body 31, with a cavity 32 on the top surface of the lens body and an integrally formed mounting ring 33 along the edge of the top surface. Furthermore, the bottom surface of the lens body is a Fresnel light-emitting surface 34, and the bottom surface of the cavity of the lens body is integrally formed with several arched surfaces 35. During use, the light from the light source plate enters through the arched surfaces and is mixed with light before illuminating outwards through the Fresnel light-emitting surfaces. The light from the light source plate enters through the arched surfaces, and the reflection and refraction of the arched surfaces facilitate uniform light mixing. The light then illuminates outwards from the Fresnel light-emitting surfaces, thereby improving the lighting effect, changing the beam angle of the LED beads, and improving illuminance and projection distance. Simultaneously, the mounting ring facilitates quick assembly and connection with the heat sink, improving the convenience and effectiveness of installation.

[0029] In this embodiment, the inner wall of the cavity is provided with semi-circular vertical protrusions 4 at equal intervals. Reflective paper 5 is attached to the inner wall of the cavity; light rays from the edge of the light source plate are reflected by the reflective paper and enter through the arched surface. The semi-circular vertical protrusions facilitate the installation and positioning of the reflective paper, and the reflection of light rays from the edge of the light source plate reduces light waste and improves the lighting effect.

[0030] Furthermore, in this embodiment, the arched surface is circular, quadrilateral, pentagonal, or hexagonal. The protrusion height of the arched surface is 1-5mm. This structure facilitates processing and improves lighting effectiveness.

[0031] Furthermore, in practical applications, the mounting ring is provided with a waist-shaped mounting hole 6; the mounting ring is attached to the bottom surface of the radiator and fixed by screws. This improves the convenience and reliability of installation.

[0032] This invention has positive effects: The structure of this invention is reasonably designed. There is a cavity on the top surface of the lens body, and the light-emitting surface of the lens body is a Fresnel light-emitting surface. Combined with the arched arc surface, light enters the lens body after being reflected and refracted by different arched arc surfaces. Then, it shines outward through the Fresnel light-emitting surface, changing the beam angle of the LED lamp bead, which is beneficial to improving the illuminance and projection distance. It is also beneficial to improve the uniformity of the lighting light and has strong applicability.

[0033] Furthermore, it features semi-circular vertical ridges and reflective paper on the inner wall of the cavity, which can reflect edge light, avoid wasting edge light, improve lighting efficiency, and have strong applicability.

[0034] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0035] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
