FIELD: electricity. ^ SUBSTANCE: lamp comprises a light diode emitter with powerful light diodes assembled on a composite cooling radiator and a body with an electronic converter of supply grid installed in it and a standard base separated with an air gap or an adapter from a material with low heat conductivity. The specified radiator of the emitter and the body may be separated from each other by an air gap with electric and mechanical connection between each other by means of a nipple with current supply facilities installed inside. The adapter may be arranged in the form of an electromechanical socket connected by current supply facilities to the radiator and the body. In this case the lamp becomes split into two parts with the possibility of individual interchangeability of the emitter with light diodes or a converter. The cooling radiator of light diodes is arranged as composite on the basis of a truncated icosahedron or a pyramid with light diodes installed on faces and a ribbed holder, besides, a part of the radiator may be enclosed into a flask filled with a heat-conductive gas, for instance, argon, so that its other part - the ribbed holder - protrudes from the flask, providing for cooling of light diodes. ^ EFFECT: improved luminous efficiency and service life. ^ 5 cl, 3 dwg |
