Abstract
A heat shield comprising a first light-reflective layer, having a reflectance peak both in a wavelength range of from 400 nm to less than 850 nm and in a wavelength range of from more than 850 nm to 1300 nm and satisfying C>A>B, is disclosed. “A” means the maximum reflectance in the wavelength range of from 400 nm to less than 850 nm; “B” means the reflectance at a wavelength of 850 nm; “C” means the maximum reflectance in the wavelength range of from more than 850 nm to 1300 nm; and “B” is equal to or less than 50%.
Claims24
A heat shield comprising:
- a first light-reflective layer comprising at least one layer formed of a fixed cholesteric liquid-crystal phase, and reflecting at least one of a right-polarized component and a left-polarized component;
- and
- a second light-reflective layer comprising at least one layer containing an organic material and/or an inorganic material;
- wherein the heat shield has a reflectance peak both in a wavelength range of from 400 nm to less than 850 nm and in a wavelength range of from more than 850 nm to 1300 nm;
- and
- satisfies C>A>B;
- where “A” means the maximum reflectance in the wavelength range of from 400 nm to less than 850 nm;
- “B” means the reflectance at a wavelength of 850 nm;
- “C” means the maximum reflectance in the wavelength range of from more than 850 nm to 1300 nm;
- and “B” is equal to or less than 50%.
A heat shield comprising:
- a first light-reflective layer comprising at least one layer formed of a fixed cholesteric liquid-crystal phase, and reflecting either a right-polarized component or a left-polarized component;
- and
- a second light-reflective layer comprising at least one layer formed of a fixed cholesteric liquid-crystal phase, reflecting a right-polarized component, and at least one layer formed of a fixed cholesteric liquid-crystal phase, reflecting a left-polarized component;
- wherein the heat shield has a reflectance peak in a wavelength range of from 400 nm to less than 850 nm, which is attributed to the selective reflectivity of the cholesteric liquid-crystal phase of the first light-reflective layer;
- and
- has a reflectance peak in a wavelength range of from more than 850 nm to 1300 nm, which is attributed to the selective reflectivity of the cholesteric liquid-crystal phase of the second light-reflective layer.
