EXPLOSION-PROOF LED LAMP Russian patent published in 2021 - IPC F21V15/00 

FIELD: light engineering.

SUBSTANCE: invention relates to light engineering, namely to explosion-proof lighting devices; it is intended for use in any conditions, both indoors and in open spaces, to provide general lighting, including in environments with a high content of explosive and flammable gases, dust and moisture. An explosion-proof LED lamp contains a light-emitting element including an explosion-proof case base coupled with a translucent lampshade with the formation of a closed volume and at least one LED emitter installed in it on the base, as well as a power supply unit connected to the LED emitter by means of a current supply, wherein the power supply unit is additionally equipped with a heating element. The power supply unit is made in the form of a detachable module isolated from the case base of the light-emitting element, and is equipped with a separate case connected to the outer surface of the case base of the light-emitting element by a detachable connection, wherein the case of the power supply unit is equipped with a detachable cover. The case base of the light-emitting element is equipped with an explosion-proof electrical connector of the LED emitter to the power supply unit, made with the possibility of a quick-detachable connection of current supply means with the LED emitter, and couplings of the LED emitter with the case base and the power supply unit are detachable. The case base of the light-emitting element can be additionally equipped with an explosion-proof breathing valve.

EFFECT: ensuring the possibility of using the lamp in conditions of a large temperature range, as well as an increase in the service life of the lamp due to an increase in the maintainability of the structure and the efficiency of heat removal with the possibility of using high-power LEDs in the design.
