Abstract
A light-accumulating luminous bulb includes a pigment for accumulating light scattered on an inside surface of the bulb. A method of making a light-accumulating luminous bulb includes preparing a mixture comprising from about one to about eight weight percent of nitrocellulose, from about five to about fifteen weight percent of camphor, and an organic solvent; combining the mixture with from about seventy-five to about ninety-five weight percent of a pigment for accumulating light, thereby forming a paint; and spraying the paint on an inside surface of a glass sphere to a thickness from about 0.1 mm to about 0.3 mm. The mixed gas is sprayed successively through three minute pipes having different-sized diameters to form film-like membranes.
