Abstract: A retrofit kit for an existing light, that has a prewired assembly, including a housing having wiring to electrical mains, an LED light source, at least one control for said LED light source, both said LED light source and said control being wired to said wiring, and said housing having a at least one mounting device that fits on existing structure of the existing light. The mounting structure can include tabs, for example, that attach to hanging part of the light, or can include a part that attaches to the existing surfaces on the housing of the light that previously held the socket for the existing bulb.

Abstract: A combined power and data track lighting system includes an elongated track, having a number of longitudinal guide ways for carrying electrically isolated power and data conductors arranged within at least some or the guide ways. An adapter applies power to the power conductors, and another adapter applies control data to the data conductors. An LED luminaire contains LEDs, each of which can generate a discrete color. A data converter converts data on the data lines to control the currents in the individual LEDs to create a desired composite color. Quartz luminaire, Metal-Halide luminaire, Digital Light Processor (DLP) automated computer luminaire, and DMX controlled devices can be supported and controlled through the track, that can be supported on trusses. The main control data is Remote Device Management (RDM) supplied applied to the data conductors.

Abstract: A combined power and data track lighting system includes an elongated track, having a number of longitudinal guide ways, for attachment to a support surface, as well as a number of current carrying conductors arranged within at least some of the guide ways. The first of these conductors are power conductors and the second conductors are data conductors, the conductors being electrically isolated from each other. The lighting system further contains a first adapter for connection to source of electrical power for the power conductors, and a second adapter for connection to a source of control data. There is at least one LED luminaire present in the system, and this luminaire contains a number of LEDs, each of which, when energized, generates a single color out of a discrete plurality of colors. A data converter converts data along the data lines to control the currents in the individual groups of color LEDs, so that they create a desired composite color.
