First Claim
1. A remotely controlled security lighting system comprised of a master control/transmitting unit and at least one remote light/receiving unit:
- A. said master control/transmitting unit comprising;
(1) means for selecting a specific light and providing a light identification signal corresponding to said light selected,(2) means for controlling the power applied to said light and providing a light-on signal corresponding to said light selected,(3) means for controlling the position of the selected said light and providing a set of light positioning signals,(4) a transmitter electronics module having the means for receiving and processing the light identification signal, light-on signal and set of light positioning signals, where the processed signals are applied to a standard first utility power connector from where the signals are communicated via the utility power lines, to a standard second utility power connector from where the signals are applied to said remote light/receiving unit,B. said remote light/receiving unit comprising;
(1) an elevation motor mechanically linked to drive said light,(2) an azimuth motor mechanically linked to drive said light,(3) a receiver electronics module having the means to be connected to the second standard utility power receptacle from where the signals from said master control/transmitting unit are received and processed to subsequently produce;
(a) a set of power and directional signals that are applied to and control the position of said light via said elevation and azimuth motors and(b) a light on or off signal that controls the application of power to said light.

Abstract
A remotely controlled security lighting system (10) that utilizes the common utility power lines of a building to provide communication between a master control/transmitting unit (12) and a plurality of remote light/receiving units (50). The unit (12) includes a light selector switch (16) that allows a particular light to be selected, a light power switch (18) that powers the selected light and a joystick (20) that positions the selected light in azimuth and elevation. The remote light/receiving unit (50) includes azimuth and elevation motors (64)(68) that are mechanically linked to the light (72), and a light power controller (70) that applies power to the light. In a typical situation, a remote light/receiving unit (50) would be attached to each upper corner of a structure and each unit (50) would be connected to the utility power line. The master control/transmitting unit (12) is then plugged into any utility power receptacle in any room; and by means of the switches (16)(18) and the joystick (20) any of the remote lights (72) can be selected, turned on and positioned.
