Abstract
A re-usable, self-illuminating sign includes a translucent plastic photoluminescent display panel, disposed within a display body, the display panel formed by distributing a photoluminescent powder uniformly throughout the plastic. A chemiluminescent light stick serves as a light source for the sign, which is in the form of a cylinder with a triangular cross section. When the light stick is exhausted, it may be removed from the display body and replaced by a new light stick. The photoluminescent display panel receives the light from the light stick, and retransmits the light uniformly throughout the display panel. A mask disposed in front of the display panel contains cutouts providing the the text and/or graphics of the sign.
Claims11
A self-illuminating sign comprising;
- (a) a display panel in the form of a cylinder with a triangular cross-section comprised of either a transparent or a translucent material which further comprises a photoluminescent powder substantially uniformly distributed throughout said display panel;
- (b) a mask, disposed in front of the display panel, the mask having a graphic formed within by means of substantially opaque portions and substantially transparent portions;
- and
- (c) one or more light sticks, disposed within the display panel, so that when the chemicals within the light stick mix, the luminous energy emitted by the light stick is absorbed by the photoluminescent powder, is retransmitted as light substantially uniformly distributed throughout the display panel, and is seen through the substantially transparent portion of the mask.
