Abstract

Described herein are lighting units of a variety of types and configurations, including linear lighting units suitable for lighting large spaces, such as building exteriors and interiors. Also provided herein are methods and systems for powering lighting units, controlling lighting units, authoring displays for lighting units, and addressing control data for lighting units.

Claims

1. A method of providing a self-healing lighting system, comprising:

providing a plurality of lighting units in a system, each having a plurality of light sources;

providing at least one processor associated with at least some of the lighting units for controlling the lighting units;

providing a network facility for addressing data to each of the lighting units;

providing a diagnostic facility for identifying a problem with a lighting unit;

providing a healing facility for modifying the actions of at least one processor to automatically correct the problem identified by the diagnostic facility.
