The solar cell carrier (9) is fastened above the hood-like casing assembly (3) at an adjustable-angle, lockable joint. Lower down, a recess (16) accommodates a reflector (17) covered by a transparent disc, making an essentially flush closure with the lower section. LED (21) sources are located at the reflector focus. The casing hood is conical or a frustrated cone. On top, it has a rotary fastening for the solar cell carrier, permitting adjustment in elevation and azimuth. |
