ABSTRACT:
An illumination/ventilation system is described wherein the light tube used to support one or more incandescent lamps forms part of the ventilation system itself. The system includes a blower having a forced air outlet with first a conduit connectings the outlet of the blower to an inlet of the light tube. A second conduit connects to an outlet of the light tube to form a circulating air path through which air is forced by the blower to ventilate the light tube. Preferably, the light tube comprises an elongate base member and an elongate light diffuser for supporting the lamps along the light tube. The light tube also includes an elongate track member having a tongue along its entire length which mates which a groove along the length of the base member to secure the track in the base member. Each of the individual lamps is supported in the elongate track member by an adapter track clip which is press-fitted, rather than twisted, into the track.
