ABSTRACT:
A modular lighting control apparatus utilizes a housing having a plurality of total electric light centers mounted therein, such that the centers may be manually activated by light beams emanating from a hand held flashlight. The housing is provided with a utility outlet receptacle and is operated by a flexible line cord which is energized by a household utility current. Each light sensor controls a character of the outlet voltage available at the output receptacle. One light sensor provides a source of continuous full voltage at the light receptacle. Another light sensor de-energizes the voltage supply to the output receptacle. Still another light sensor causes the voltage, present at the output receptacle, to become intermittent. Yet another light sensor determines the amount of voltage available at the output receptacle. Such housing, utilizes alone or in combination of others, may be installed in conjunction with a Christmas tree lighting apparatus so as to remotely turn on and off lights in various strings about the tree, lights in miniature buildings disposed near the base of the tree and other electrically operated apparatus such as humidifiers or play-back devices of the acoustical variety.
