Description

Technical Field

[0001] The utility model relates to the technical field of LED explosion-proof lamps, in particular to a high-temperature resistant LED explosion-proof platform lamp. Background Art

[0002] High temperature resistant LED explosion-proof platform lights are lighting equipment specially designed for hazardous environments (such as chemical plants, oil fields, mining areas, etc.), which can provide safe and efficient lighting under harsh working conditions such as high temperature, high pressure, flammable and explosive. The existing high temperature resistant LED explosion-proof platform lights include explosion-proof lamp housings, lampshades, lampshade fixing sleeves and explosion-proof lamp back covers. In actual use, it is found that they have the following shortcomings: 1. Since the explosion-proof lamp housing and the explosion-proof lamp back cover need to be fixed by multiple screws, and there is no other positioning structure between the two, when working at high altitude, it is easy to fall during disassembly or incomplete installation, causing safety hazards; 2. When the LED explosion-proof platform lights need to be maintained, due to high altitude operations, the explosion-proof lamp back cover needs to be manually held or temporarily suspended after disassembly, which increases the burden on maintenance personnel and reduces maintenance efficiency. Improvements and optimizations are made for this. Utility Model Content
