Title:
APPARATUS FOR PRODUCING AN OPTICAL EFFECT OR FOR SIMULATING FIRES AND SIMULATED FIREPLACES INCLUDING SUCH APPARATUS
Document Type and Number:
WIPO Patent Application WO2006040167
Kind Code:
A3
Abstract:
Apparatus for producing an optical effect includes a screen comprising at least one electroluminescent material and associated electrodes for exciting the electroluminescent material to emit light. The electrodes are locally excitable so that the regions of the electroluminescent material generally in the shape of flames may be excited. In an alternative form, or additionally, the screen comprises a material of variable opacity such as a liquid crystal polymer or a suspended particle device. gain, electrodes are locally excitable to locally change the opacity of the screen. The screen is locally illuminated to provide the impression of flames.
