Power track and method of mounting and connecting a light modulator to supported luminaires

1. A light fixture coupleable to a track power system, the light fixture comprising:

a housing mechanically couple able to the track power system;

a connector port coupled to the housing, the connector port having input terminals and output terminals, the connector port configured to electrically isolate the input terminals from the output terminals;

a driver positioned within the housing, the driver having a driver input and a driver output, the driver input electrically coupleable to the track power system and configured to receive an input voltage from the track power system, the driver output coupled to the output terminals of the connector port; and

a light emitting unit coupled to the housing, the light emitting unit having a light emitting unit input coupled to the input terminals of the connector port.

2. The light fixture of claim 1 , wherein the connector port is configured to selectively receive one of a light modulator or a jumper plug to couple the input terminals to the output terminals.

3. The light fixture of claim 2 , wherein:

the jumper plug includes jumper plug input terminals and jumper plug output terminals; and

each jumper plug input terminal is coupled to a respective jumper plug output terminal.

4. The light fixture of claim 2 , wherein the jumper plug is configured to provide a constant electrical connection between the driver and the light emitting unit.

5. The light fixture of claim 2 , wherein the modulator includes a modulator input coupled to the output terminals and a modulator output coupled to the input terminals, the modulator input configured to receive electrical power from the driver output, and the modulation output configured to provide modulated electrical power to the light emitting unit.

6. The light fixture of claim 2 , wherein the modulator is configured to modulate light emitted from the light emitting unit.

7. The light fixture of claim 2 , wherein the modulator is directly coupled to the connector port.

8. The light fixture of claim 2 , wherein the modulator is coupled to the connector port via a cable.
