First Claim
1. A luminaire, comprising:
- a first reflector having an inner space and an inner surface that includes a light mixing portion;
a second reflector having an inner space and an inner surface, the second reflector being at least partially disposed within the inner space of the first reflector;
a third reflector having an inner space, an inner surface, and an outer surface, wherein light emitted from a lamp at least partially disposed within the inner space of the third reflector is reflected by a portion of the inner surface of the third reflector and exits through an opening of the third reflector;
the third reflector being at least partially disposed within the inner space of the second reflector;
a plurality of colored light sources disposed within the inner space of the first reflector, wherein light emitted by the plurality of colored light sources is reflected by the light mixing portion of the inner surface of the first reflector and passes through a plenum formed by a portion of the outer surface of the third reflector and a portion of the inner surface of the second reflector; and
a control module coupled to the plurality of colored light sources that controls an intensity of each of the plurality of colored light sources.

Abstract
The present invention provides systems and apparatuses for dynamically controlling the operational modes of a single luminaire or a group of networked luminaires configured to deliver an illumination pattern having a decorative colored glow surrounding a central region of substantially uniform brightness. A control module for the luminaire is configured to drive three dimmable fluorescent ballasts, as well as a LED module. A variety of operational modes including different schemes for color mixing and color cycle control can be selected by a user and implemented by a microcontroller. A group of luminaires is connected in a standard communication protocol-based master-slave configuration, where the slave units respond to commands received from the master unit, and the last slave unit automatically engages terminating and biasing resistors for proper operation of the network.
