摘要： A light source device comprising a filament showing high electric power-to-visible light conversion efficiency is provided. A light source device comprising a translucent gastight container, a filament disposed in the translucent gastight container, and a lead wire for supplying an electric current to the filament is provided. The filament comprises a substrate formed from a metal material and a visible light reflectance-reducing film coating the substrate for reducing visible light reflectance of the substrate. The reflectance of the substrate for visible lights is thereby made low, and the reflectance of the substrate for infrared lights is thereby made high. Therefore, radiation of infrared lights is suppressed, and visible luminous efficiency can be enhanced.

摘要： A light source device comprising a filament showing high electric power-to-visible light conversion efficiency is provided. A light source device comprising a translucent gastight container, a filament disposed in the translucent gastight container, and a lead wire for supplying an electric current to the filament is provided. The filament comprises a substrate formed with a metal material and a white scatterer layer covering the substrate. To the white scatterer layer, a visible light-absorbing material that absorbs lights of visible region is added. The reflectance of the filament for visible lights is thereby made low, and the reflectance of the filament for infrared lights is thereby made high. Therefore, radiation of infrared lights is suppressed, and visible luminous efficiency can be enhanced.

摘要： An object of the present invention is to provide a filament showing improved conversion efficiency with a simple configuration. According to the present invention, surface of a filament material processed into a predetermined shape is processed into a mirror surface by mechanical polishing, and surface roughness (center line average roughness Ra) thereof is thereby made to be 1 μm or smaller. Reflectance of the filament can be thereby improved, and emissivity of the filament for lights of the infrared wavelength region can be suppressed.
