Apparatus mounted with heat-insulation light-guide film

Abstract

The disclosure is related to an apparatus mounted with a heat-insulation light-guide film. The apparatus is a support with carriers capable of adjusting the received light quantity. The carrier is such as the slat of a shutter device and whose angle is adjustable. The heat-insulation light-guide film is exemplarily mounted on the slat, and which is made of a multilayer membrane and a surface textural layer in combination. The multilayer membrane includes multiple films and the adjacent layers are with different indexes of refraction. The materials and thicknesses of the membrane are configured to specify an optical band of light to be reflected. The surface textural layer is for guiding an incident light directed to the structure. The apparatus is as required to adjust the angle of the light hitting the film, and is applicable to a window for uses of heat-insulation, anti-glare, and illumination.
