Illumination/ventilation system and track light fixture
First Claim
1. An illumination/ventilation system for a display case comprising:
- a hollow, enclosed light tube mounted in the display case and having an inlet and an outlet, the light tube including means for supporting one or more lamps interior of and along its length;
a blower supported by the display case and having a forced air outlet; and
conduit means supported in the display case and including a first portion and a second portion each having an inlet and an outlet, the first portion connected between the blower outlet and the enclosed light tube inlet and the second portion connected to the enclosed light tube outlet to form an enclosed air path through which air is forced by the blower to ventilate the light tube and expel heat generated by said lamps.

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.

7. An illumination/ventilation system for a display case, comprising:
-
a light tube mounted in the display case and having an inlet and an outlet, the light tube for supporting one or more lamps along its length, the light tube comprising; an elongate base member having a groove along substantially its entire length; an elongate track member having a tongue along substantially its entire length, the tongue of the track member cooperating with the groove of the base member to secure the track to the base member; and an elongate diffuser supported by the base member to form a substantially closed channel in the light tube. a blower supported by the display case and having a forced air outlet; and conduit means supported in the display case and including a first portion and a second portion each having an inlet and an outlet, the first portion connected between the blower outlet and light tube inlet and the second portion connected to the light tube outlet to form an air path through which air is forced by the blower to ventilate the light tube. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. An illumination/ventilation system for a display case comprising:
-
a hollow, enclosed light tube mounted adjacent a top portion of the display case and having an inlet and an outlet, the light tube including means for supporting one or more lamps on its interior and along its length; a blower supported by the display case and having an inlet and a forced air outlet; conduit means imbedded in the display case and including a first portion and a second portion each having an inlet and an outlet, the first portion connected between the blower outlet and the enclosed light tube inlet and the second portion connected to the enclosed light tube outlet to form an enclosed air path through which air is forced by the blower to ventilate the light tube and expel heat generated by said lamps; and means supported in the first and second portions of the conduit means for changing the direction of the air flow through the air path. - View Dependent Claims (15, 16, 17, 18, 19)
