Filed: 1992-01-10
Abstract: PURPOSE:To prrmit the arrangement with high density, with high luminance and low heat generation by forming the upper edge surface of a cylindrical glass bulb to a light output part, installing a fluorescent body layer on the inner walls of the side surface and the lower edge surface, installing an outside electrode on the outer surface and inserting an inside electrode from the lower edge surface. CONSTITUTION:When a voltage is applied between an inside electrode 3 and an outside electrode 4 on the outer peripheral surface of a glass bulb 2 from a power source 6, the rare gas (xenon) inside tha lamp is applied with a voltage through the glass made of dielectric, and electric discharge occurs. The generated ultraviolet ray excites a fluorescent body layer 7 formed nearly the whole surface of the inner wall except the upper edge surface of the bulb 2, and is converted to visible light ray. This light repeats reflection on the inner wall of the bulb, and outputs radiation concentrically from a light output part 8 having light transmissiveness. Accordingly, high luminance can be obtained with a small electric power, and the concentration of the electric discharge to a specific place is prevented, and since the light is generated from the whole inner surface of the bulb 2 faced to the electrode 4, the increase of the electric current density is prevented.
