Abstract
Abstract A lighting control system includes a plurality of lighting control modules where each module includes function switches for generating command signals to control light intensity levels to run a plurality of lighting channels connected thereto. A programmable central processing unit transmits the command signals and also generates an ID code indicating a unique identity for each. The light control modules are interconnected on a local area network for carrying the ID codes and the command signals. Each of the lighting control modules is programmable for selecting predetermined ID codes whereby command signals generated by selected control modules may be executed by other control modules.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
120 words
A lighting control system comprising: (a) a plurality of lighting control modules, each said module having (i) function switches for generating command signals to control light intensity levels, (ii) a plurality of lighting channels responsive to the command signals, (iii)a programmable central processing unit for transmitting the command signals and for generating an ID (identification) code indicating a unique identity; (b) local area network means for interconnecting said plurality of lighting control modules and for carrying the ID code and command signals; and (c) programming means associated with each of said lighting control modules for selecting predetermined ID codes whereby command signals generated by selected ones of said control modules may be executed by other ones of said control modules.
Claim 2
Dependent Claim
120 words
A lighting control system comprising: (a) a plurality of lighting control modules, each said module having (i) function switches for generating command signals to control light intensity levels, (ii) a plurality of lighting channels responsive to the command signals, (iii)a programmable central processing unit for transmitting the command signals and for generating an ID (identification) code indicating a unique identity; (b) local area network means for interconnecting said plurality of lighting control modules and for carrying the ID code and command signals; and (c) programming means associated with each of said lighting control modules for selecting predetermined ID codes whereby command signals generated by selected ones of said control modules may be executed by other ones of said control modules.
Claim 3
Dependent Claim
56 words
The lighting control system of claim 1 further including remote switch means coupled to said local area network means for generating lighting level command signals and a digital code, said remote switch means controlling lighting levels on control modules which are programmed to accept said command signals from said remote switch means having predetermined digital codes.
Claim 4
Dependent Claim
33 words
The lighting control system of claim 2 wherein said remote switch means comprises at least one preset remote unit having function switches for controlling lighting levels on a plurality of lighting channels simultaneously.
Claim 5
Dependent Claim
27 words
The lighting control system of claim 3 wherein said remote switch means comprises at least one raise/lower remote switch for generating a raise/lower lighting level command signal.
Claim 6
Dependent Claim
46 words
The lighting control system of claim 1 wherein said programming means comprises a switch located on each of said lighting control modules for placing each module in a programming mode whereby said function switches are transformed to execute preselected programming functions for said central processing units.
Claim 7
Dependent Claim
48 words
The lighting control system of claim 1 wherein each of said modules includes visual means for indicating the intensity of light on each of said lighting channels and whereby said visual means provides visual verification for said preselected programming functions while said modules are in said programming mode.
Claim 8
Dependent Claim
121 words
In a lighting system controlled by microcomputer apparatus for programming the computer from a useraccessible panel to control lighting level functions on a plurality of channels comprising: (a) a plurality of light function switches having normally designated lighting control functions; (b) programming control means for placing the microcomputer in a program mode and for assigning programming functions to said lighting function switches different from said normally designated lighting control functions whenever predetermined ones of said function switches are depressed simultaneously with said programming control means placing the microcomputer in said program mode; and (c) learn control means for locking into a memory the programming function selected by the simultaneous depression of the programming control means and the selected lighting function switch.
Claim 9
Dependent Claim
121 words
In a lighting system controlled by microcomputer apparatus for programming the computer from a useraccessible panel to control lighting level functions on a plurality of channels comprising: (a) a plurality of light function switches having normally designated lighting control functions; (b) programming control means for placing the microcomputer in a program mode and for assigning programming functions to said lighting function switches different from said normally designated lighting control functions whenever predetermined ones of said function switches are depressed simultaneously with said programming control means placing the microcomputer in said program mode; and (c) learn control means for locking into a memory the programming function selected by the simultaneous depression of the programming control means and the selected lighting function switch.
Claim 10
Dependent Claim
33 words
The lighting system of claim 7 further including visual indicator means for normally indicating lighting intensity levels and responsive to said programming means for providing a visual code indicating a particular programming function.
