Description

Technical Field

[0001] The present invention relates to the field of lighting technology, and in particular to a light bar installation structure of a triple-proof lamp. Background Art

[0002] Tri-proof lamps are waterproof, dustproof and anti-corrosion lamps, usually used in railways, electric power, metallurgy, petroleum and petrochemical and various factories, stations and large facilities, venues and other places that require high-brightness projection lighting. There are usually two possibilities for tri-proof lamp failures. One is the failure of the driving power supply, and the other is the failure of the light bar. In the current existing structure, the light bar is inconvenient to disassemble and even difficult to disassemble and replace. As a result, in many cases, the tri-proof lamp that cannot be used normally due to the failure of the light bar can only be replaced as a whole, which makes the use cost higher.
