1. A modular track lighting system comprising:
- a plurality of extended reflector hoods, each of said extended reflector hoods having first and second longitudinal sides and a web extending between the first and second longitudinal sides, the web having an upper web surface and a lower web surface;
the upper web surface cooperating with the first and second longitudinal sides to define an upper channel having an open top and the lower web surface cooperating with the first and second longitudinal sides to define a lower channel having an open bottom;
at least one assembly bridge having a generally inverted U-shaped cross-sectional shape and sized to be received within the upper channel, each of said at least one assembly bridge comprising a first vertical portion, the first vertical portion having a first channel slidably receiving a first longitudinal rail formed on an inward facing surface of the first longitudinal side, a second vertical portion, the second vertical portion having a second channel slidably receiving a second longitudinal rail formed on an inward facing surface of the second longitudinal side, and a transverse portion extending between the first vertical portion and the second vertical portion;
an extended cover having a generally inverted U-shaped cross-sectional shape, said extended cover comprising a first vertical portion slidably receivable over the first longitudinal side, a second vertical portion slidably receivable over the second longitudinal side, and a transverse portion extending between the first vertical portion and the second vertical portion to at least partially enclose the open top of the plurality of extended reflector hoods.

Abstract
A modular lighting system features a universal mounting method for lighting elements, such as LED lights, as well as various electrical devices, and is configurable in multiple modes of operation. In one aspect, LED strips are inserted into slots in the lower surface of the rail member. Another aspect allows operation with tube lamps, such LED tube lamps. In still another mode of operation, discrete electrical or electromechanical components may be employed, powered by electrical power available in the rail. In yet another more, an up and down, bidirectional lighting system is provided.
