APPARATUS FOR DIGITAL COMMUNICATIONS WITH MULTIPARAMETER LIGHT FIXTURES
First Claim
1. A multi-parameter light fixture comprising:
- a lamp assembly comprising a plurality of components for implementing parameters;
an electronics module comprising a first digital communications node and a second digital communications node;
the first digital communications node being addressable from and networkable in a first external communications system and having a first control output coupled to the lamp assembly for controlling at least one of the parameters; and
the second digital communications node being addressable from and networkable in a second external communications system and having a second control output coupled to the lamp assembly for controlling at least one of the parameters; and
a gateway circuit coupled between the first digital communications node and the second digital communications node.

Abstract
A typical light fixture is an integral unit that has a lamp assembly and a communications node to control the lamp assembly. Lighting systems contain many such light fixtures. One type of lighting system has at least two communications systems that interconnect the light fixtures. A digital controller is connected to one of the communications systems, at least one of the light fixtures of that communications system is a designated gateway for sending control signals to the other communications system. Another type of lighting system has two digital controllers connected to respective communications systems. Each of the communications systems interconnects many light fixtures, at least one of which has two communications nodes respectively connected to the communications systems. A third type of lighting system mixes combines the first and second types.
