摘要:
An improved seal member is provided as a part of an electrochromic device to bond two glass elements together in a spaced-apart relationship. In one embodiment the seal member provides improved adhesion to a reflector/electrode on the third surface of an electrochromic mirror, or to a layer of metal on the second or third surface for an electrochromic light filter. This seal member comprises a mixture of an organic resin sealing system and an adhesion promoter, where the adhesion promotor comprises a first and a second region, where the first region interacts with the reflector/electrode or the metal layer, and a second region that interacts with the organic resin sealing system, and may even chemically react with the organic resin sealing system. In another embodiment the seal member is provided with a coefficient of thermal expansion that is closer to glass than a standard epoxy sealing system.
摘要:
An improved electrochromic rearview mirror for motor vehicles, the mirror (110) incorporating thin front and rear spaced glass elements (112, 114) having a thickness ranging from about 0.5 to about 1.5. A layer of conductive material (118a-c) is placed onto the mirror's second surface (112b), and either another layer of transparent conductive material or a combined reflector/electrode (120) is placed onto the mirror's third surface (114a). A chamber (116), defined by the layers (112b, 114a) on the interior surfaces of the front and rear glass elements (112, 114) and a peripheral sealing member (122), contains a free-standing gel (124) comprising a solvent and a cross-linked polymer matrix. The chamber (116) further contains at least one electrochromic material in solution with the solvent and interspersed in the cross-linked polymer matrix. The gel (124) co-operatively interacts with the thin glass elements (112, 114) to form a thick, strong unitary member which is resistant to flexing, warping, bowing and/or shattering and further allows the mirror (110) to exhibit reduced vibrational distortion and double imaging.

A window assembly includes a pressure pane and a bezel proximate a periphery of the pressure pane and defining an inner opening. The bezel includes an inner wall with a channel. An electro-optic element is disposed in the inner opening and is received in the channel of the inner wall. The electro-optic element operates between a transmissive condition and a dimmed condition. A surface of the electro-optic element exhibits a first level of spectral reflectivity at least when in the dimmed condition. The assembly further includes a dust cover assembly proximate the bezel. The dust cover assembly including a light transmitting sheet and a plurality of light sources disposed at edges of the light transmitting sheet and to emit light into the light transmitting sheet to illuminate the light transmitting sheet with a diffuse light.

摘要:
An electrochromic window assembly (10) is disclosed that includes a first substrate (12) and a second substrate (14) that is maintained in a parallel and spaced relation from the first substrate by means of a window frame (16) and spacer (18). The window assembly further includes an electrochromic device (22) mounted in the airtight chamber formed between the first and second substrates. Electrochromic device (22) may be mounted so as to provide an air chamber between first substrate (12), which is the external substrate, and electrochromic device (22). At least one of the chambers formed between substrates (12) and (14) and electrochromic device (22) may be filled with an insulating gas such as argon. Also disclosed are novel methods for manufacture of an electrochromic device for incorporation into such a window assembly. A novel electrochromic device is also disclosed having electrical bus clips (40a, 40b) secured about the entire periphery of the electrochromic device. Also disclosed is the use of steel bus clips for the electrochromic device.
