Abstract:

A LED luminaire track lighting system includes an elongate track, having a number of longitudinal guideways, for attachment to a support surface, as well as a number of current conductors arranged within at least some of the guideways. 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 a source of electrical power for the power conductors, and a second adapter for connection to a source of control data for application of data to the data conductors. There is at least one LED color-changing 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. Further, at least electrically, the LED color-changing luminaire is at least electrically connected to the power conductors and data conductors in the track.
