Patent ID: 7826704

Claim:
A Low-E glass, comprising: a glass substrate; and a multilayer Low-E film formed on at least one surface of the glass substrate, the multilayer Low-E film comprising a plurality of high refractive index layers and a plurality of low refractive index layers stacked one on another; wherein an innermost layer of the multilayer Low-E film nearest to the surface of the glass substrate is one of the high refractive index layers, each high refractive index layer is configured as an odd-numbered layer of the multilayer Low-E film, and each low refractive index layer is configured as an even-numbered layer of the multilayer Low-E film; a physical thickness of each high refractive index layer and each low refractive index layer is equal to λ/4n H and λ/4n L , respectively, wherein λ is a wavelength of light rays to be reflected by the Low-E glass, and n H and n L are refractive indexes of the high and low refractive index layers, respectively; and a total number of layers of the multilayer Low-E film is in a range from 30 to 40.
