FIELD: electricity.SUBSTANCE: LED lamp is related to light engineering, in particular, to sources of general lighting. It consists of a light-diffusing shell made of optically transparent material; a ring-shaped hollow radiator; a concave reflector equipped with diffusely reflective continuous surface placed in the radiator cavity; light-emitting diodes generating light flux directed towards the lamp axis, the LEDs are fixed at inner surface of the radiator with possibility of radiation of the above reflector surface; facility generating light flux, which is installed between the reflector and the light-diffusing shell.EFFECT: technical result lies in improvement of lighting comfort, even brightness of the light-emitting surface.16 cl, 3 dwg |
