FIELD: electricity.
SUBSTANCE: invention is related to semiconductor light engineering, in particular to a light-emitting diode lamp for general and special applications, for example, in explosion-proof luminaries. The lamp is designed with a light emitter made of at least two elongated and individually protected LED modules or lines assembled in a thermal contact area on individual cooling radiators separated in space, mounted in meridian planes in parallel or at an acute angle to the longitudinal axis of the lamp and coupled to a converter of the supply mains placed in a separate insulated chamber. Each LED module or line is encapsulated into a tubular and optically transparent bulb with a long slot and an elongated radiator with cooling fins protruding from the slot along its whole length, the radiator is connected by a channel for current-carrying facilities to the chamber of the supply mains converter.
EFFECT: improvement of the lamp heat parameters due to increase in surface for convective heat transfer of the radiators.
