本文介绍有关利用可见光透射红外反射膜将白炽灯中没有被有效利用的红外辐射返回到灯丝中作为热再利用、节能化卤灯的结构、原理和最近的研制动向。这项技术于80年代进入实用化。最初是应用于有圆筒状石英管的卤灯,后来,由于膜特性的提高和改善、以及灯性能、结构等的改进等,开展了向各种灯的推广应用,节能达15%～25%,实现了高效率化。最近,由于膜特性的高性能化和与球及旋转椭圆体等最佳灯管形状的组合,已用于新的、一般单灯头汽车用卤灯和带分色镜的卤灯等,其节能效率达30%。
This article describes the structure, principles, and recent developments in the use of visible light-transmissive infrared reflecting films to return infra-red radiation not effectively utilized in incandescent lamps to filaments as a heat re-use, energy-saving halogen lamp. This technology was put into practical use in the 1980s. Originally, it was applied to the halogen lamp with a cylindrical quartz tube. Later, due to the improvement and improvement of the film characteristics and the improvement of the lamp performance and structure, etc., the promotion to various lamps was carried out, saving 15% to 25% %, To achieve high efficiency. Recently, the high performance of film characteristics and the combination of the best lamp shapes such as balls and spheroids have been used in new, general single-head automotive halogen lamps and dichroic mirror-mounted halogen lamps and the like, and their energy saving Efficiency up to 30%.
