    • PROBLEM TO BE SOLVED: To provide an infrared reflecting structure 10 which efficiently reflects infrared radiation in response to an external stimulus such as temperature.
      SOLUTION: The infrared reflecting structure 10 comprises an infrared reflecting laminate 20 consisting of a plurality of laminated infrared reflecting materials 22 and a temperature-sensitive member 30 disposed in contact with a lateral face of the infrared reflecting laminate 20. The infrared reflecting materials 22 comprise colloidal crystal grains 23 arrayed at regular spacing and an expansive-contractile material 24 interposed between the colloidal crystal grains 23. The temperature-sensitive member 30 supplies moisture to the expansive-contractile material 24 according to temperature, and by swelling of the expansive-contractile material 24, the spacing of the colloidal crystal grains 23 is varied. The spacing changes reflection wavelength from an ultraviolet region to an infrared region based on Bragg's law and Snell's law, whereby the amount of transmission of infrared radiation is efficiently regulated.

    • 要解决的问题:提供一种红外反射结构10,其响应于诸如温度的外部刺激有效地反射红外辐射。 解决方案:红外反射结构10包括由多个层叠的红外反射材料22和与红外反射层压体20的侧面接触设置的感温元件30组成的红外反射层压体20。 材料22包括以规则间隔排列的胶体晶粒23和介于胶体晶粒23之间的膨胀 - 收缩材料24.感温构件30根据温度向膨胀收缩材料24提供水分,并且通过膨胀 膨胀收缩材料24,胶体晶粒23的间隔变化。 基于布拉格定律和斯涅尔定律,间隔将反射波长从紫外区域改变为红外区域,从而有效地调节红外辐射的透射量。 版权所有(C)2008,JPO&INPIT
