Description

technical field [0001] The invention relates to the field of mine lighting, in particular to a waterproof lampshade for underground mines. Background technique [0002] There are many defects in miner's lamps in the prior art. Because the bulbs of miner's lamps are of different sizes, for example, LED bulbs are used to increase the lighting brightness, and the bulbs are installed in the lampshade and cannot be adjusted, so different lampshades are required, resulting in waste of resources. In addition, miner's lamps are often used in mines, etc. When used in a humid environment, it will often be damaged due to water ingress. When using the miner's lamp in the mine, it will be touched by ore. The operator will also easily drop the miner's lamp during operation, which not only affects the use, but also increases the cost of use. Contents of the invention [0003] The invention provides a waterproof lampshade for underground mines, which has a simple structure, not only facil...
