Abstract
Light dispersive insulated glazing units are disclosed. The light dispersive insulated glazing units comprise two lites of glazing material, spaced apart from and opposing one another and a visible light dispersive film, such as a hologram or diffraction grating, interposed between confronting surfaces of the lites. Methods for producing these light dispersive insulated glazing units are disclosed, as well.
Claims37
A light dispersive insulated glazing unit, comprising:
- (a) a support structure;
- (b) a first glazing lite attached to said support structure;
- (c) a second glazing lite attached to said support structure so that said second glazing lite is opposing said first glazing lite and is spaced apart from said first glazing lite;
- and
- (d) a light dispersive film interposed between said first glazing lite and said second glazing lite.
A light dispersive insulated glazing unit, comprising:
- (a) a support structure;
- (b) a first glazing lite attached to said support structure;
- (c) a second glazing lite attached to said support structure so that said second glazing lite is opposing said first glazing lite and is spaced apart from said first glazing lite;
- and
- (d) a light dispersive film interposed between, and spaced apart from, the opposing surfaces of said first glazing lite and said second glazing lite, at least a portion of the perimeter of said light dispersive film being attached to said support structure to hold said visible light dispersive film in suspension between, and spaced apart from, said first glazing lite and said second glazing lite.
A method of manufacturing a light dispersive insulated glazing unit, comprising the following steps:
- (a) forming a substantially sealed integral unit comprising a pair of spaced glazing lites and a heat-shrinkable light dispersive film interposed between said glazing lites and spaced apart from said glazing lites, said light dispersive film being fixed along at least two of its edges with respect to the edges of said glazing lites;
- and
- (b) heating the sealed unit to cause the light dispersive film to shrink and become taut and substantially wrinkle free between said glazing lites.
A light dispersive insulated glazing unit, comprising:
- (a) an outer glazing lite for initially receiving light, said outer glazing lite having an outer surface and an inner surface;
- (b) an inner glazing lite spaced apart from the outer glazing lite, said inner glazing lite having an inner surface opposing the inner surface of said outer glazing lite;
- and
- (c) a flexible light dispersive film laminated to the inner surface of said inner glazing lite for diffracting light transmitted through the outer glazing lite.
