FIELD: electricity.
SUBSTANCE: lamp comprises a cover of a light source chamber, a radiator, a diffuser, a threaded ring, a power supply circuit board and a light diode circuit board, a sealing ring, a junction box and a cable input connected to the cover of the light source. The radiator is made in the form of a cylindrical bushing with external ribbing and with an inner partition, at one side of which there is a light diode circuit board, and at the same side there is a diffuser tightly mounted from heat-resistant light-stabilising polycarbonate, pressed to the end of the cylindrical bushing with a threaded ring, and at the other side of the partition there is a power supply circuit board, poured with the heat-conducting compound into the jacket and closed at the appropriate end of the bushing with a cover of the light source chamber to produce a cavity. At the same time between the cover and the radiator there is a sealing ring, besides, the cover, the radiator and the diffuser are installed to form an explosion-proof enclosure.
EFFECT: higher repairability, reliability of assembly, safety of design, higher extent of protection against environment.
