摘要： PURPOSE:To absorb IR light by reflecting visible light and to decrease the content of the IR light projected light by providing a film which allows transmission of IR light and reflects visible light on the opposite surface of an IR absorptive base body facing a light source. CONSTITUTION:An IR absorptive film 13 is a shaded color film consisting of a heavy metallic oxide formed by treating an aluminum base body 11. Said film is dense and thin and absorbs IR light well. A visible light reflective film 14 is formed by superposing alternately plural layers of a material having a high refractive index and a material having a low refractive index and reflects visible light well by light interference and absorbs IR light well. The visible light of the light emitted from a filament 23 is thereupon reflected and projected forward by the film 14 of a reflector 1. The IR light transmitted through the film 14 is made incident to the film 13 where the light is absorbed and converts to heat. The heat is released from the surface of the base body 11 into the atm. The IR light to be incorporated in the projected light of an electric bulb is thus decreased.
