Abstract
PURPOSE: To raise the temperature of the wall of a light permeable bulb by means of a reflecting film which can reflect infrared ray into the bulb while allow a visible light to permeate when emitted from a filament, provided on the outer surface thereof.
CONSTITUTION: Argon, chloroform (CHCl)3 and hydrogen are sealed off in a quartz bulb 1. In this bulb 1, a filament 20 having an illuminating section 2 and a non-illuminating section 3 is so supported on supporters 4 as to be placed in the center thereof. In addition, the filament 20 is connected to an external leading-in wire 7 through a molybdenum foil at a pinch seal section 5. The outer surface of the bulb 1 is coated with a reflecting film 9 which reflects infrared ray and allow a visible light such as TiO2-Ag-TiO2 to permeate. When the lamp is on, infrared ray is reflected on the film 9 and returned to the inside thereof to heat the gas therein, whereby the temperature of the bulb is raised.
