Also disclosed are processes for manufacturing the disclosed bubble visors.
Claims26
A curved electrochromic device comprising an electrochromic apparatus disposed between first and second curved layers of transparent material, and the first and second curved layers have exterior and inner surfaces, wherein the inner surfaces face the electrochromic apparatus, and wherein the exterior surface of the first curved layer of transparent material is provided with a coating that blocks wavelengths of visible radiation capable of initiating chemical decomposition of the electrochromic apparatus.
An electrochromic device having a layer of transparent polymeric material connected to an electrochromic apparatus, wherein the transparent polymeric material comprises
- a coating opposite the electrochromic apparatus and that is capable of reflecting infrared and ultraviolet wavelength radiation;
- a coating opposite the electrochromic apparatus and blocks wavelengths of visible radiation capable of initiating chemical decomposition of an electrochromic compound;
- or
- a dielectric coating capable of transmitting light within the range of about 400 nm to 700 nm.
A helmet comprising a visor comprising an electrochromic device, wherein the electrochromic device comprises an electrochromic apparatus disposed between first and second curved layers of transparent material, and the first and second curved layers have exterior and inner surfaces, wherein the inner surfaces face the electrochromic apparatus.
An electrochromic device comprising an electrochromic apparatus disposed between first and second curved layers of transparent material, and the first and second curved layers have exterior and inner surfaces, wherein the inner surfaces face the electrochromic apparatus.
