Description

Technical Field

[0002] With the development of the lighting market, people's demand for lamps is increasing, and lamps with a single angle can no longer meet people's daily lighting needs.

[0003] At present, the angle adjustment of mining lamps is mainly achieved in the following three ways on the market:

[0004] One is to adjust the angle by changing the distance between the lens and the light source and adjusting the focal length of the lens. This method will cause changes in optical efficiency after adjusting the focal length, resulting in a loss of luminous flux;

[0005] The second method is to adjust the angle by adjusting the relative position of the two layers of lenses and changing the light path. This method requires two layers of optical structure, resulting in a large loss of light flux.

[0006] The third method is to use twice the number of light sources, with two lenses at different angles, and adjust the angle by adjusting the brightness of the two light sources. This method requires a large number of lamp beads and is costly. At the same time, the light spot is a simple superposition of two different angles, and the lighting effect is poor.

[0010] In order to facilitate the rotation of the lens, a symmetrical handle is further provided on the periphery of the lens surface.

[0011] In order to install functional parts, such as microwave sensors, and increase the functionality of the entire lamp, a reserved groove is further provided in the middle of the lens.
