"SUN LAMP" SOLAR ILLUMINATION DEVICE Russian patent published in 2013 - IPC F21S9/02 

FIELD: power industry.

SUBSTANCE: device includes a transparent dome made in the form of an upper plane-convex diverging lens (PCDL), the plane surface of which is parallel to the light-guide tube inlet plane. Side curved surface of the dome represents sector-like PCDLs adjacent to each other and located inside the transparent dome, a circular PCDL and a central PCDL adjacent to it. Straight protective cone (SPC) with an outside solar battery located on its surface, an inverted flattened cone (IFC) with inside mirror surface; at that, plane surface of central PCDL constitutes together with IFC generatrix and angle of 90° and is parallel to the light-guide tube (LGT) inlet plane. In lower part of LGT there located is a flat circular damper with mirror surface, which is fixed on the shaft of an electric micromotor. Lower straight cone (LSC) is located relative to LGT so that solar beams enter it when leaving LGT. On the inside side surface of the above LSC there located is a circular solar battery, and its basis is provided with a diffusing dome lamp, around which a light-emitting-diode lamp with inside mirror surface. The device has a control panel with an electronic relay, which is intended for control of an electric micromotor and a light-emitting-diode lamp.

EFFECT: improving efficiency of colour rendering and enlarging operating capabilities owing to being used during cloudy period of the day and night-time.
