Abstract: A lamp box with a color variable light source comprises a metal halide lamp, a bowl-like reflector, a power source, a filter and a drive motor in its body. The body of the lamp box is connected with optical fibers through a fiber optic plug. The fiber optic plug comprises a fiber optic internal sleeve, a fiber optic position sleeve, a position pole, a holder and a rear base seal sleeve. The fiber optic internal sleeve is settled inside the fiber optic position sleeve. The holder, the fiber optic position sleeve and the fiber optic internal sleeve are fastened by the position pole. Even if the fiber optic position sleeve and the optical fibers in the fiber optic internal sleeve rotate, the fiber optic plug will not depart from the body of the light source lamp box.

Abstract: A polyvinyl chloride (PVC) composition includes an active fluorescence or phosfluorescence inducing agent which causes the composition to emit a brighter or hotter appearing light, as compared to conventional PVC compositions, when exposed to white light. In one form, the PVC composition includes barium diphenylaminesulfonate as an additive in a clear or transparent composition and light passing through the composition appears to be hotter than the impinging light. In another form, the additive is barium carbonate and the PVC includes a tinting agent to induce a colored glow when exposed to white light. In all forms, the fluorescence or phosfluorescence inducing agent is selected from a class of materials having the characteristics of creating a compound having an outer electron shell which will permit an electron shift between shells when exposed to light.
