The general-purpose light-emitting diode lamp relates to the field of lighting engineering and, more specifically, to light sources intended for use in general-purpose lighting devices. The technical result of the invention is increased manufacturability of the design of the lamp, improved thermal behaviour of the light-emitting diodes, and increased lighting comfort in terms of the uniformity of the glow from the light-emitting envelope and the colour temperature thereof. The invention comprises light-emitting diodes disposed on a board that is mounted longitudinally to the axis of the lamp, a power source mounted on an isolated surface of the light-emitting diode board, and a radiator having at least two detachable parts which secure the board on a surface region situated between the light-emitting diodes and the power source, wherein the parts of the radiator are fastened together at one end by a connection to an electrical network and, at the other end, by an optically transparent envelope. In an embodiment in which the light-emitting diodes are disposed on a continuous cylindrical surface, the board is produced on a flexible base and is secured to an additional longitudinal hollow component of the radiator. |
