ABSTRACT:
To improve the cooling efficiency and ensure uniform cooling of all portions of the inside back surface of the reflector, a deflector (108) has been developed. The air deflector (108) typically encircles the lamp (102) allowing air (110) to flow between the deflector (108) and the lamp (102). This air (110) cools the lamp (102). Air (112) passing between the deflector (108) and the reflector (100) is deflected outward to cool the inside surface of the reflector near the lamp (102). Because the deflector (108) is small and is located directly behind the lamp (102), it does not block any of the useful light generated by the lamp (102). The light striking the deflector (108) from the lamp (102), if not for the deflector (108), would have passed through the opening in the reflector (100) and would have been lost. The deflector (108) typically has a number of vanes around the perimeter of a cylindrical body portion. The vanes are bent outward at an angle sufficient to force part of the cooling air to flow across the inside back surface of the reflector.
