Abstract
Embodiments described include bus bars for electrochromic or other optical state changing devices. The bus bars are configured to color match and/or provide minimal optical contrast with their surrounding environment in the optical device. Such bus bars may be transparent bus bars.
Claims22
An electrochromic glass structure, comprising:
- a substantially transparent substrate;
- an electrochromic device coating disposed on the substantially transparent substrate, the electrochromic device coating having one or more transparent conductive layers;
- a bus bar configured to power the electrochromic device;
- and
- a strip of obscuration material along entire perimeter of the electrochromic glass structure, the strip of obscuration material located on a surface of the electrochromic glass structure between the bus bar and an exterior environment to the electrochromic glass structure.
2 more elements
An insulated glass unit comprising:
- first and second substantially transparent substrates;
- a spacer between the first and second substantially transparent substrates;
- a primary seal between the spacer and the first substantially transparent substrate and between the spacer and the second substantially transparent substrate;
- an electrochromic device on at least one of the first and second substantially transparent substrates;
- and
- a bus bar associated with the electrochromic device and located under the spacer and in the primary seal, wherein the bus bar is located under the spacer and in the primary seal;
- and
- a strip of obscuration material along entire perimeter of the insulated glass unit, the strip of obscuration material located on a surface of one of the first and second substantially transparent substrates between the bus bar and a region outside the insulated glass unit;
- wherein the bus bar is obscured from sight by the obscuration material when viewed from a first side of the insulated glass unit.
