Abstract
A low voltage display lamp is provided for use in standard threaded lamp sockets. The lamp has a heat shield to reflect infrared radiation (IR) away from the ballast to reduce the ballast's operating temperature. The surface of the heat shield is optically curved to direct the reflected IR back through the front of the lamp such that it exits through the transparent cover rather than being reflected into the lamp housing.
