ABSTRACT:
A light-sensitive lamp adaptor is small enough to fit in most indoor or outdoor lamps between the lamp socket and the light bulb. The adapter contains a solid state electronic circuit including a photocell which is in good thermal contact with the thermally conductive base of the adapter so that these electrical components are not heated excessively. A small window in the side of the adapter is movable about the axis of the adapter so that the photocell will respond only to light incident on the window from a given direction and the size of the window can be adjusted so that the unit will respond only to light of a given intensity.
