LED BULB

The invention relates to lighting technology, and specifically, to designs of general-purpose LED bulbs. The technical result of the claimed solution is an improvement in the removal of heat from light-emitting diodes and from a power source, and an increase in the manufacturability and lighting efficiency of a bulb. The LED bulb comprises a body-cum-radiator (1) covered with a dielectric heat-conductive plastic; a base plate with light-emitting diodes; a diffuser (5) covering the light-emitting diodes; a power source; and a cap (7). The body-cum-radiator (1) comprises two combined aluminium profiles (8), the inner and outer surfaces of which are covered with a dielectric heat-conductive plastic, the outer wall has extended ends (11) and a flat surface section which is equipped with heat-removing cooling fins (12), wherein the heat-removing fins of a first part of the body-cum-radiator are oriented towards the heat-removing fins of a second part of the body-cum-radiator and mounted with a gap (13); the base plate of the light-emitting diodes is mounted on flat sections of the surface of each aluminium profile; and the extended ends (11) of the outer wall of each aluminium profile are connected to the cap (7) with the aid of the dielectric heat-conductive plastic, from the material of which an enclosure (14) is formed for accommodating the power source, the enclosure being separated from the aluminium profile by an air gap (15).
