The invention relates to lighting technology, and more particularly to light-emitting diode lamps having a printed circuit board and a screw cap (Edison cap) for connection to an electric power supply network. The technical result of the claimed invention is a simplified lamp design as a result of a reduced number of structural and fastening components. The present light-emitting diode lamp comprises a hollow body-cum-radiator; an optically transparent diffuser, fastened to the body-cum-radiator; light-emitting diodes, mounted on a printed circuit board, which is arranged on an end face of the body-cum-radiator such as to be capable of heat exchange; an elongate dielectric plate, disposed along the longitudinal axis of the lamp; a power supply; and a screw cap in the form of a hollow thin-walled cylinder, having a contact element fastened to the bottom thereof, wherein a first remote part of the elongate plate has two projections, adapted for mechanical connection with the light-emitting diode board, and a second remote part of the elongate plate is disposed in the cavity of the cap and is provided with a perforation, adapted for threaded connection with the cap. The projections of the first remote part of the elongate plate are metallized for electromechanical connection with tracks in the light-emitting diode board. |
