Description

Technical Field

[0001] The utility model relates to a one-end pull-out type three-proof lamp. Background Art

[0002] Tri-proof lamps are waterproof, dustproof, and corrosion-resistant. They are generally used in industrial lighting environments with high corrosion, dust, and rain exposure, such as power plants, steel mills, petrochemical plants, ships, and open-air venues. Tri-proof lamps come in both integrated and split styles. Split-type tri-proof lamps typically have a lamp base and lampshade connected by a snap-on connection. While these tri-proof lamps are easy to install and disassemble, they suffer from poor overall sealing. Integrated tri-proof lamps feature a one-piece tubular structure, manufactured using a two-color extrusion process and an integrated molding extrusion process. End caps are added to both ends of the lamp holder, providing better overall sealing. However, the internal parts of the tubular lamp housing are difficult to disassemble and replacement is troublesome. Utility Model Content
