A sunlight collecting and concentrating apparatus having a mirror or lens device rotated independently about a vertical and horizontal axis, respectively, so that the mirror or lens always faces the sun when despite change is in the sun's azimuth and altitude. An optical conductor is provided which has a first section arranged coaxially with the horizontal axis and a second section arranged coaxially with the vertical axis. Means are provided between the first and second conductors for allowing relative rotation therebetween. Thus, no winding torsion of the conductors take place during the rotational movement of the mirror about the first and the second axes. Means are also provided for preventing winding or torsion of cable for transmission of signals from the tracking sensor device to a control circuit for operating the mirror. |
