Patent

CA 2576814

Side lighting of a transparent panel with etched features to scatter light towards an observer provides a physically robust alternative to neon tube technology. In particular, a number of advantages can be realized by using chip on board (COB) LED technology. COB LEDs (107) offer particular advantages in allowing use of low operating voltages as well as control over the intensity and color of the displays. Other advantages are realized by aligning two or more panels (101), each with a portion of a design, and independently varying the color or intensity of light.

L~éclairage latéral d~un panneau transparent avec des caractéristiques de gravure pour disperser la lumière contre un observateur qui donne une alternative robuste sur le plan physique à la technologie du tube au néon. Particulièrement, de nombreux avantages peuvent être réalisés en utilisant la technologie de la puce sur carte (COB) LED. Les puces sur cartes (107) offrent des avantages particuliers en permettant l~utilisation de basses tensions de fonctionnement ainsi que le contrôle de l~intensité et de la couleur des affichages. Des avantages supplémentaires sont réalisés en alignant deux ou plusieurs panneaux (101), chacun avec une partie du modèle et variant indépendamment la couleur ou l~intensité de la lumière.
