Image projecting light bulb

摘要

A display system that includes a projector light bulb. The system includes a light fixture with a conventional light bulb socket. A projector light bulb is provided with a socket adapter for mating electrically with the light bulb socket. A projector such as a pico projector is fit into the socket adapter or to mate with this adapter to be powered by the light bulb socket via the adapter. In lamp-type implementations, the projector is used to project onto a lamp shade-shaped rear projection screen or through a translucent shade and also upon surfaces of the ceiling or objects above the projector light bulb. A light conditioning or directing assembly may be provided that directs a portion of the projected light onto the projection screen (or shade) and another portion up onto the ceiling so as to concurrently focus on two or more surfaces at two or more focal distances.
