SOLAR ILLUMINANT DEVICE Russian patent published in 1995 - IPC

FIELD: lighting engineering. SUBSTANCE: illuminant solar device has rotary screen which has any section be provided with sun-light collector, member for removing energy and mechanism of zenithal and azimuthal rotation of the screen provided with drive 6. Light-dissipating elements 8 are introduced into the device, mounted on any illuminated part according to number of sections of the screen which is mounted onto support 2. The elements are optically conjugated with corresponding sun-light collector. Any sun-light collector is made of single flat mirror 4 at least. Zenithal rotation mechanism with drive is made in form of reducer 7. Output shaft of the reducer is connected with zenithal axis of the screen. The reducer is provided with step-down gearing. Engine is connected with drive gear of the reducer. Energy removing element is made in form of a primary photoelectric solar energy converter 5 and mounted at the center of symmetry of the screen. The screen sections are disposed symmetrically in relation to its axis of symmetry. EFFECT: improved efficiency; improved comfort. 2 dwg
