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 insulated glass unit (IGU) 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 in the primary seal, the bus bar camouflaged to blend in with its background.
3 more elements
An electrochromic glass structure comprising:
- a substantially transparent substrate;
- an electrochromic device disposed on the substantially transparent substrate, the electrochromic device having one or more transparent conductive layers;
- a bus bar configured to power the electrochromic device;
- and
- an opaque obscuring layer located in a region between the bus bar and the substantially transparent substrate.
2 more elements
An IGU comprising:
- a first pane having a first substantially transparent substrate, an electrochromic device disposed on the first substantially transparent substrate, the electrochromic device comprising a first transparent conductive layer proximal the first substantially transparent substrate, an electrochromic stack, and a second transparent conductive layer;
- a second pane having a second substantially transparent substrate;
- a spacer between the first and second panes;
- a primary sealant adhering the spacer to the first and second panes;
- a pair of bus bars on the first transparent conductive layer, nearest the first pane;
- and
- one or more transparent bus bars on the second transparent conductive layer.
4 more elements
An IGU or laminate comprising:
- a) an electrochromic device on at least one transparent substrate, of at least two transparent substrates of the IGU or laminate;
- and
- b) at least one transparent bus bar configured to electrically power the electrochromic device.
