Lighting communication architecture
First Claim
1. A lighting control system for stage lighting control system comprising:
- a lighting control console, having control mechanisms which operate to control a number of different types of stage lamps, said lighting control console having an output signal that has information for a plurality of said stage lamps, said output signal being in a standard format for computer systems;
a distribution rack, physically separated from said lighting control console, and receiving said output signal from said lighting control console, said distribution rack including a surface having a plurality of connectors, and interface circuitry which translates between said output signal from said lighting control console, and signals which are applied to said connectors, said connectors including;
a first connector which includes terminals which send information for lighting devices in which each lighting device is controlled over a dedicated line;
a second connector which includes terminals which send information for lighting devices which operate according to a time division multiplexed format, and in which only one time division multiplexed device is controlled over each separate line.

Abstract
An improved lighting control architecture provides many different kinds of controlling options. A single channel per line communication is described. This can be used to form single channel DMX to communicate with DMX format luminaires, while still using only one communication per line. The controlling console has only a single connector that outputs information for all luminaires. This is connected to a distribution rack, which itself includes plural connectors but spaced from the console. The multiple connectors can represent communications in many different formats including format of one lamp per line, or time division multiplexed formats of many lamps per line.

4. A lighting control system for stage lighting comprising:
-
a lighting control console, having control mechanisms which operate to control a number of different types of stage lamps, said lighting control console producing a single output signal that has information for a plurality of said stage lamps, said output signal being in a standard format for data communication in computer systems;
a distribution device, physically separated from said lighting control console, and receiving said single output signal from said lighting control console, and converting said single output into a plurality of distribution outputs, said distribution outputs including at least;
a first output which provides information for lighting devices in which said information is in a time-division multiplexed format, but only a single lighting device is controlled over each line; and
a second output which provides information for lighting devices in which said information is in a time-division multiplexed format, but multiple lighting devices are controlled over each line.

5. A lighting control system for a stage lighting control system comprising:
-
a lighting control console, having control mechanisms which operate to control a number of different types of stage lights, said lighting control console having an output signal that has information for a plurality of said stage lamps, said output signal being in a standard format for computer systems, and including a number of lines of communicated information, said number of lines being less than a total number of stage lights being controlled;
a distribution rack, physically separated from said lighting control console, and receiving said output signal from said lighting control console, said distribution rack including a surface having a plurality of connectors, and interface circuitry which translates between said output signal from said lighting control console, and signals which are applied to said connectors, said connectors including;
a first connector array which includes terminals which send information for lighting devices in which each lighting device is controlled over a dedicated line and a number of lines of which is the substantially the same as a total number of stage lights being controlled and at least one of said lights operates according to a time division multiplexed format; and
a second connector array which includes terminals which send information for lighting devices which operate according to a time division multiplexed format.

6. A method of communicating with a stage light, comprising:
-
forming a time division multiplexed message, with a plurality of time slots in the message, each said time slot being intended for a different stage light;
placing desired information for only a desired one of said stage lights into only a single time slot of said message, and leaving other time slots, other than said single time slot, without information for other stage lights therein to form a single channel time division multiplexed message; and
sending said single channel time division multiplexed message to a stage light that communicates in a time division multiplexed format, and thereby communicating with only said stage light using said single channel time division multiplexed format. - View Dependent Claims (7, 8, 9)
