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.Field of SearchRemote adjustment or positioning meansWith actuator Electric or pneumatic Condition responsive Electromagnetic actuator With rheostat or switch Electromagnetic operator controls movable light support POSITION OR CONDITION RESPONSIVE SWITCH Synchronous distributor at transmitter and receiver Signal light systems Combined with power line | |
