Abstract
Abstract An optical display apparatus includes a plurality of optical elements of acrylic material and an additive. Each optical element is shaped into cylindrical body with a first convex end and a second convex end to improve light receiving and transmitting efficiency of the optical element. By activation of a fluorescent lamp, the optical elements can emit ultra-bright color light. A light reflective chamber encloses the fluorescent lamp and the optical elements. Through a panel of the chamber and the optical elements mounted on the panel via apertures of the panel, various desired display patterns may be accomplished. The additive may be fluorescent color dyes or bleaching power. The optical display apparatus further includes a convex lens, a color disc and a motor. The motor drives the color disc to rotate so that light rays focus by the convex lens have variable colors. By means of optical-coupling means, the variable-color light rays are reflectively transmitted to some of optical elements to generate abundant color lights.
