FIELD: lighting.

SUBSTANCE: explosion-proof LED lamp contains a radiator body made by extrusion from an aluminium alloy and made with two compartments in the form of a monoblock. The first is an electrical compartment made in the form of a tubular channel, hermetically sealed at opposite ends with lids with axially installed cable entries with plugs, in which a power unit with terminal blocks is installed in the compartment. The second is an optical compartment made in the form of a flat rectangular holder, to which a LED module, closed with polycarbonate diffuser, is attached to the front side. The bracket for fixing the luminaire is installed on the side of the electrical compartment. To achieve the technical result, the luminaire is equipped with a block lens mounted on top of the LED module and fastened with screws, a pressure plate that fastens the polycarbonate diffuser to the holder with fixing screws, two power supply brackets fixed in longitudinal grooves made in diametrically located projections in the tubular channel and fixed in it from the axial movement by two plates fastened with screws to the same protrusions, the terminal blocks being installed on the said plates.

EFFECT: high luminous efficiency, simplification of assembly and installation of the luminaire, increased efficiency, reliability of the luminaire design and its service life.
