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.摘要翻译： 提供了一种包括显示高电力 - 可见光转换效率的灯丝的光源装置。 提供一种光源装置，其包括半透明气密容器，设置在半透明气密容器中的灯丝和用于向灯丝供电的引线。 灯丝包括由金属材料形成的基板和涂覆基板的可见光反射率降低膜，用于降低基板的可见光反射率。 由此，可见光用基板的反射率变低，因此红外线用基板的反射率变高。 因此，抑制红外线的照射，可以提高可见光的发光效率。
