| Title: |
Image Projector For Use With Luminaires |
| Abstract: |
An image projector that drops into the accessory slot of a luminaire and
projects high quality images printed on plastic slides in full color and
photographic detail for extended time periods without heat degradation.
The projector comprises a cooling fan, infrared and ultraviolet light
filter means, and an inexpensive and removable slide assembly comprising a
plastic image slide, a protective film slide and at least one mounting
plate. The cooling fan is combined with layered, reflective filters to
create a protected environment for the plastic image slide to survive the
extreme heat at the gate of today's efficient luminaires. The plastic
image slide is created on a plastic sheet using conventional computer
printing technologies.
