The case is adapted to be mounted vertically, for example, on a wall. The significance of liquid moisture protection was generally not appreciated.Ī preferred embodiment of the fiber optic illuminator system according to the present invention comprises an illuminator case and a chassis mounted within the case. It was generally not appreciated that heavy wattage light bulbs, up to as much as 500 watts or more, could be used as the light source without causing thermal damage and without complicated and expensive heat sinks or other heat dissipation expedients in a system with no light leakage, very low noise emission and with moisture protection. Optionally, hot or cold mirrors were previously utilized to reflect visible light and absorb or pass infrared and ultraviolet light. In general the components of previous fiber optics illumination systems included a high intensity light source, a color wheel or filter assembly, a fan assembly and a low output voltage transformer all mounted within a closed case. It is believed that this constriction results in the formation of a region of positive pressure within the illuminator, the formation and benefits of which were generally not previously appreciated. It was not generally appreciated that the utilization of a very open air flow path or labyrinth for cooling purposes is not inconsistent with these objectives provided the air outlet is somewhat more constricted than the air inlet. Previous expedients generally did not recognize that the presence of those elements and features which are necessary to provide good thermal protection is generally inconsistent with the objectives of no light leakage, very low noise level and moisture. Previous fiber optics light generating systems have recognized that thermal protection is necessary for the various components within the light generating system, the light conduit and the surrounding environment. lamps, incandescent bulbs, scintillation chambers G02B6/4298- Coupling light guides with opto-electronic elements coupling with non-coherent light sources and/or radiation detectors, e.g.G02B6/42- Coupling light guides with opto-electronic elements.G02B6/00- Light guides Structural details of arrangements comprising light guides and other optical elements, e.g.G02B- OPTICAL ELEMENTS, SYSTEMS OR APPARATUS.F21V31/00- Gas-tight or water-tight arrangements.F21V15/00- Protecting lighting devices from damage.air characterised by the arrangement of fans ![]()
