1. A method of powering and controlling a set of light fixture loads in a low voltage distribution system comprising:
- converting power for powering the set of light fixture loads;
limiting converted power to multiple current outputs supplied to the set of light fixture loads;
delivering the multiple current outputs to the set of light fixture loads via a set of cables; and
transmitting output current information to the set of light fixture loads via said set of cables;
wherein the output current information includes on time value, an off time value and a period value wherein none of the values are held constant.

Abstract
The disclosure is directed at a method and apparatus for configuring and powering light fixture loads for a LED low voltage distribution system. The method and apparatus include converting power being supplied for powering the set of light fixture loads and then limiting this converted power to a set of multiple current outputs supplied to the light fixture loads. The multiple current outputs are then split or regrouped prior to being delivered to the light fixture loads.

8. Apparatus for powering and controlling a set of light fixture loads in a light emitting diode (LED) low voltage distribution system comprising:
-
a power circuit including a power limit for limiting power supplied to the set light fixture loads; a set of load controllers for controlling the set of light fixture loads; a set of cables connected to an output of the power circuit and to outputs of the set of load controllers and to inputs of the set of light fixture loads; and a communication interface for receiving dimming or color mixing information; wherein the dimming or color mixing information includes output current information encoded with three variables where no three variables are held constant, the three variables including on-time, off-time and period; wherein the set of cables deliver both the limited power and data to the set of light fixture loads. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 17)
