Chromogenic window assembly construction and other chromogenic devices

A chromogenic block, comprising:

• a first panel;
• a second panel wherein at least one of said first and second panels has a curved surface;
• a chromogenic member having an optical property which varies according to an applied signal, said chromogenic member being disposed between said first panel and said second panel;
• wherein by varying the optical property of said chromogenic member, an amount of radiation passing between said first panel and said second panel can be regulated;
• and
• wherein said chromogenic member comprises two separate, flat electrochromic panels.

A chromogenic skylight comprising:

• a chromogenic member having an optical property which varies according to an applied signal;
• an outer panel disposed proximate to said chromogenic member, said outer panel being dimensioned and disposed so as to overlap at least a substantial part of said chromogenic member;
• and
• wherein said chromogenic member comprises at least two separate, flat electrochromic panels.

A chromogenic aircraft window to be installed in an aircraft, said aircraft having a surface contour, said chromogenic aircraft window comprising:

• a chromogenic member having an optical property which varies according to an applied signal;
• an outer panel proximate to said chromogenic member, said outer panel being dimensioned and at a position so as to overlap at least a substantial part of said chromogenic member, said outer panel having a predetermined panel contour corresponding to the surface contour;
• and
• wherein said chromogenic member comprises two separate, flat electrochromic panels.
