A travelling lighting system for a greenhouse includes a plurality of lamps supported on an elongated truss which is slowly advanced back and forth across a greenhouse bay to provide lighting for the plants therein. The truss may be supported by trolleys carried in a pair of parallel spaced apart tracks extending the length of the greenhouse bay. A power drive system advances the truss along the tracks. A power cord support rail may be provided above the truss to collect and support the electrical power cord to the truss at spaced apart locations along the cord to prevent sagging as the truss is advanced toward the electrical power source.

[ I claim:] [1.] A travelling lighting system for a greenhouse including a roof support structure and a floor having floor space for growing plants at multiple positions throughout said floor space, comprising:an elongated, substantially horizontally disposed lamp support beam;a plurality of lamps supported at spaced apart locations along said lamp support beam;a pair of elongated, substantially horizontally disposed tracks supported above said floor in parallel spaced apart relation for movably supporting said beam;said tracks having longitudinal axes disposed transversely with respect to the longitudinal axis of said beam;at least one trolley movable along each track and connected to said beam whereby said beam substantially spans the distance between said tracks and is moldable along the length of said tracks;a power drive system operatively connected to said beam and actuatable to reciprocally move said beam back and forth along the length of said tracks to light the plants therebelow.
