The infrared reflective film (IRC) technology is a typical example of the application of new materials in the field of light source. By recycling the heat emitted by the filament, the IRC halogen lamp has a higher luminous efficiency and longevity than the conventional halogen lamp. Great improvement. The film layer used in the Osram IRC series halogen lamp is a multi-layer structure composed of a superposition of SiO2 having a low refractive index and TiO2 having a high refractive index. When the light from the filament passes through the structure of the film, only a very small amount of infrared light and visible light pass through the film layer and are transmitted, and most of the infrared spectrum having a wavelength exceeding 780 nm is reflected back to the filament. In order to improve the efficiency of infrared recycling of filaments, OSRAM IRC series halogen lamps use a special bulb and filament design, glass bulbs with ellipsoid shape can achieve the best reflection effect; and optimized design with special geometry The filament absorbs the reflected infrared light optimally, so that the heat remains inside the lamp housing, thereby achieving the purpose of recycling energy and reducing the external electrical energy required to bring the filament to normal operating temperature. Osram IRC halogen lamps are divided into three product lines, namely HALOSTAR IRC, DECOSTAR IRC and HALOLINE IRC. It can directly replace the traditional halogen lamp series. Under the condition of consuming the same energy, not only the light output can be increased by 30-50%, but also the life is extended by one time. Excerpt from Consumer Daily, 2001.6.6
