Abstract: A method and apparatus for a lamp housing is provided that blocks light and dissipates heat. The lamp housing encases or is integral to a reflector, and has an inner surface that absorbs radiation emitted by the lamp burner and an outer surface that allows for improved heat dissipation through radiation and convection means. The inner surface absorbs radiation and the outer surface is enlarged with a plurality of formations for improved heat dissipation through radiation and convection means. The housing also blocks stray visible light from escaping, thereby reducing or eliminating the need for light leakage systems.

Abstract: The present invention provides an image-rendering device for an image projector. The image-rendering device includes a body having an image receiver adapted to alternatively receive a first interchangeable data transfer device and a second interchangeable data transfer device. Each interchangeable data transfer device is adapted to enable transfer of an image to the image-rendering device. The body may further include a projector connector adapted to operably couple the image-rendering device to the image projector and a processor configured to automatically transmit the image from the image receiver to the image projector for display. In some embodiments, the image-rendering device includes a peripheral device connector configured to enable at least one peripheral device to be operably linked to the image-rendering device. The peripheral device connector may be configured to transmit an image from the at least one peripheral device to the image projector, or vice versa.
