[0023] Embodiment

[0024] See Figures 1 to 4 As shown, a mining lamp with a diffuse reflection matrix glass lens includes a lamp body 2 having a light source cavity 1, and a light source board 3 is fixed in the light source cavity. In this embodiment, both the lamp body and the light source board are conventional structures of the prior art and are only simply applied, so they are not described in detail; in this embodiment, the top surface of the glass lens refers to the surface in contact with the light source board, which is only for convenience of description and does not limit it.

A plurality of matrix-shaped lamp bead cavities 5 are provided on the top surface of the glass lens. A hemispherical concave cavity 6 is provided at the bottom of the lamp bead cavity. During processing, the lamp bead cavity and the hemispherical concave cavity are concentrically arranged, and the diameter of the lamp bead cavity is larger than the diameter of the hemispherical concave cavity; the matrix-shaped lamp bead cavities adopted can be used in cooperation with different lamp beads on the light source board, so that the light of different lamp beads irradiates outward from different lamp bead cavities and is mixed by the glass lens, improving the uniformity and effectiveness of irradiation.

[0026] In this embodiment, a conical diffuse reflection concave hole 7 is integrally formed on the side wall of the lamp bead cavity; a plurality of frustum-shaped diffuse reflection protrusions 8 are integrally formed on the cavity wall of the hemispherical concave cavity; a reflective paper layer 9 is provided on the top surface of the glass lens; during use, the conical diffuse reflection concave hole is conical. The glass lens is attached to the top wall of the light source cavity through the reflective paper layer, and the lamp beads of the light source board are located in the lamp bead cavities. The light is scattered and mixed through the reflection and refraction of the conical diffuse reflection concave hole and in cooperation with the reflection and refraction of the frustum-shaped diffuse reflection protrusions, thereby improving the uniformity and softness of the light output and also improving the light transmittance.

[0027] In this embodiment, the light-emitting surface of the glass lens is a wide-angle light-transmitting curved surface 10, and a concave arc surface 11 is provided at the center position of the wide-angle light-transmitting curved surface. The light is dispersed through the concave arc surface, and the light will not be overly concentrated at the center, avoiding center high brightness. Specifically, as shown in Patent 201720212614.5, it is beneficial to improve the lighting effectiveness.

[0028] Moreover, in this embodiment, an installation convex ring 12 is integrally formed at the lower part of the edge of the glass lens; during assembly, the installation convex ring is attached to the bottom surface of the lamp body and fixed by a screw 13. Through the above structure, the stability and reliability of the connection can be improved, and it is also convenient for disassembly, assembly and maintenance. And a sealing glue layer 14 is provided between the contact surface of the installation convex ring and the lamp body. The waterproof performance can be improved.

[0029] The utility model has positive effects: The structure of the utility model is reasonably arranged. A lamp bead cavity is arranged on the glass lens, a hemispherical concave cavity is arranged at the bottom of the lamp bead cavity, and at the same time, conical diffuse reflection concave holes are arranged on the side wall of the lamp bead cavity to cooperate with the frustum-shaped diffuse reflection protrusions on the inner wall of the hemispherical concave cavity, so that the light of the lamp beads can be refracted and reflected multiple times, thereby improving the effect of diffuse reflection illumination, making the illumination light effect more uniform, having a higher light transmittance, improving the illumination effect, and having strong applicability.

At the same time, the connection methods of each component adopt the mature conventional means in the existing technology, and the machines, parts and equipment all adopt the conventional models in the existing technology, so no specific description will be made here.
