ABSTRACT:
A tubular skylight is provided with a solar-powered light damper unit that includes a damper supported by an axle within a light-conveying tube, a solar cell, and a motor powered by the solar cell. The motor includes a cam that connects to the axle and that rotates the damper between a fully open position and a fully closed position. The solar cell is housed protectively within the skylight assembly, and may be attached to one of the damper itself or an interior surface of the light-conveying structure. The damper unit may be operated by remote control. The unit may be provided with new skylight installations or may be sold separately for retro-fitting existing installations.
