To improve the cooling efficiency and ensure uniform cooling of all portions of the inside back surface of the reflector, a deflector () has been developed. The air deflector () typically encircles the lamp () allowing air () to flow between the deflector () and the lamp (). This air () cools the lamp (). Air () passing between the deflector () and the reflector () is deflected outward to cool the inside surface of the reflector near the lamp (). Because the deflector () is small and is located directly behind the lamp (), it does not block any of the useful light generated by the lamp (). The light striking the deflector () from the lamp (), if not for the deflector (), would have passed through the opening in the reflector () and would have been lost. The deflector () 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.

An alignment tool ( ) designed to replace a high-powered lamp with a low-powered lamp to facilitate safe alignment of a projector lamp console. The alignment tool ( ) comprised of a cathode portion ( ) and an anode portion ( ) connected by one or more rods ( ). The alignment tool holds a light source such as a flashlight ( ) having an exposed bulb ( ) in the approximate location of the arc of the high-powered lamp. The cathode and anode sockets and the reflector of the projector lamp console are adjusted until the exposed bulb ( ) is at the F1 focal point of the reflector and the optical axis of the alignment tool is the optical axis of the reflector.

A housing for a compact high intensity lamp. The housing has a shell whose inner surface generally conforms to the outer profile of the lamp, except at the lamp face. A small air space exists between the inner surface of the shell and the outer profile of the lamp. The shell receives air at an air intake port, and the air circulates in the air space, and exits from an air exhaust port. The shell and the lamp both rest on an alignment collar, that aligns the lamp to the shell and aligns the lamp to other equipment with which it is to be used.
