CLAIMS
1. Remote control of public illumination by computer , characterized by control of the public illumination starting from a computerized central station. Remote control of public illumination by computer, in agreement with the claim 1, characterized by sending digital codes in an unique frequency of radio for control of the illumination intensity. Remote control of public illumination by computer, in agreement with the claimsl and 2, characterized by small controllers microprocessed for each lamp that should be controlled. Remote control of public illumination by computer, in agreement with the claims 1, 2 and 3, characterized by small controllers microprocessed that receive digital commands for wave of radio. Remote control of public illumination by computer , characterized by controllers microprocessed that in the absence of a command, after a certain period of time, they are capable to realize a standard control scheduled previously.
Description:
REMOTE CONTROL OF PUBLIC ILLUMINATION BY COMPUTER Remote Control Of Public Illumination By Computer refers the present invention to a system of control of public illumination of streets, avenues and squares, constituted by a computerized central station, that sends commands by wave of radio to small controllers each one controlling one lamp, turning on, turning off or varying the intensity of the illumination of this lamp.

The commands sent by the central station are digital, so that with a unique frequency of wave carrier it is possible to control each lamp individually.

Each command is a digital code, that identifies a controller and the brightness that is desired for the controlled lamp.

All the controllers receive all the digital codes, when a controller recognizes that the received digital code correspond to it, it executes the variation of brightness according to the information contained in this code.

The controllers are microprocessed and in the absence of a command, after a period of certain time, they are capable to realize a control standard scheduled previously.
