Abstract

Functionally, the present invention illuminates an otherwise dark room when motion is detected by a motion sensor, causing the switch to close and the illumination means to light and stay lit for a set time after the motion sensor does not detect motion. In one aspect, the motion actuated lighting device of the present invention is enclosed in a housing which contains: a power source, illumination means, motion sensor, electrical circuit, and time delay means to turn off the light if the motion sensor no longer detects motion. The device may further consist of a light sensor or photocell and the associated circuitry for nighttime operation. In another aspect of the invention, the elements of the lighting device are modular. For example, while the motion sensor may be located in a doorway or at the foot of a bed, the illumination means may be located in another room, such as a bathroom, and the photocell may be located close to a window.
