Abstract
PURPOSE:To indicate clearly the residual life of a fluorescent lamp by furnishing a substance to assume coloring or color change due to ultraviolet rays in a position nearer the end than the filament. CONSTITUTION:In a fluorescent lamp, the light receiving intensity for ultraviolet rays is so distributed as smaller at the end of a lamp base 1 than places from filament 4 to the center. A coloring film 5 which assumes coloring or color change when receiving ultraviolet rays is installed in a position nearer the end than the filament 4, and thereby the time for coloring or color change of the coloring film 5 can be delayed. Thus the life of florescent lamp can be judged by the coloring film which assumes coloring or color change after passage of a time corresponding to the life of the fluorescent lamp.
