Description

Technical Field

[0001] The utility model relates to the technical field of industrial and mining lamps, in particular to an anti-falling industrial and mining lamp. Background Art

[0002] LED mining lamps, also known as high bay lights, are lighting devices that mainly use light-emitting diodes as light sources. They are high-efficiency indoor LED lamps. They are gradually coming into people's field of vision with their advantages such as directional light emission, low power consumption, good driving characteristics, fast response speed, high seismic resistance, long service life, and green environmental protection. They can be widely used in industrial plants, production workshops, supermarkets, sports and entertainment venues, warehouses and other scenarios.

[0003] LED mining lamps are mainly composed of a driving power supply, an aluminum alloy heat sink, a light source, and a PC lens. The lighting beam angle of existing LED mining lamps is mainly constrained by the PC lens to produce the required angle. Currently, there is a technical method to adjust the angle, specifically: manually rotating the lens in three gears to adjust the zoom. After production is completed, the LED mining lamp can be manually switched between the three different set beam angles according to demand.

[0004] However, this type of mining lamp is prone to improper adjustment during actual use. Specifically, after adjustment, the connection part may become unstable, resulting in a loose connection between the lamp body and the lens. In addition, there may be misalignment or inadequate adjustment, that is, the relative position between the lens and the housing is not adjusted to the correct position, or the lens is not completely fixed in the predetermined position. This can easily cause the lens to detach from the housing during operation of the mining lamp, posing a safety hazard.

[0005] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content
