A light source for a light conduit illumination system, comprising: (a) a housing having sidewalls and a top and a bottom; (b) a high-intensity lamp mounted within said housing; (c) at least one light conduit having two ends, one said end being a light-receiving end, the other said end being a trans

A light source for a light conduit illumination system, comprising: (a) a housing having sidewalls and a top and a bottom; (b) a high-intensity lamp mounted within said housing; (c) at least one light conduit having two ends, one said end being a light-receiving end, the other said end being a transmitting end, said light-receiving end being disposed within said housing on a line-of-sight with said lamp; (d) a concave light focusing reflector disposed adjacent said light source along said line-of-sight such that said lamp is between said light-receiving end of said light conduit and said lamp, for focusing the light from said light source at a focal point remote from said light source, with said light-receiving end of said light conduit being disposed near said focal point; (e) a light-transmitting envelope enclosing said light-receiving end of said light conduit secured within said housing, and means for sealing said light-transmitting envelope, thereby preventing deterioration of said light conduit due to chemical reactions with air; and (f) a fan disposed between said lamp and said light-receiving end of said light conduit, said fan positioned to blow directly on said light-receiving end of said light conduit, and means for driving said fan.
