| Title: |
Image Projection Lighting Device |
| Abstract: |
An improved image projection lighting device is disclosed. Commands
received by a communications port of the base housing may be acted upon to
change zoom and focus values of a zoom and focus lens. A cooling system
may be provided which compares an input air temperature of the image
projection lighting device to an exiting air temperature to determine if a
filter needs service. A video projector may project a first image
comprised of first, second, and third separate images and the first
separate image can be faded up to project light that is void of an image
by a first command received at the communications port.
