Publication number: 20220390804Abstract: An article can include a non-light-emitting, variable transmission device and a coating disposed between the non-light-emitting, variable transmission device and an ambient outside the article. In an embodiment, the article has a ?E of at most 6.5. In another embodiment, the coating includes a plurality of layers including a first layer having a refractive index of at least 2.2 and a thickness of at least 10 nm. The coating can be used to help reduce color differences seen when the non-light-transmitting, variable transmission device is taken to different transmission states. In a particular embodiment, the coating can provide a good balance between color difference and luminous transmission.Type: ApplicationFiled: August 18, 2022Publication date: December 8, 2022Inventors: Julien ORILLARD, Alexandre RICHARD, Paul C. MOGENSEN, Nicolas Antoine MERCADIER, Henry KELLEY, Mathew BOWSER

Patent number: 9226366Abstract: The present invention relates to a lighting control system, comprising a control unit comprising a memory in which control programs are recorded. The control programs are capable of controlling the optical transmission through an active window pane with electro-controllable optical transmission properties and are capable of controlling an electro-controllable lighting device. The system furthermore comprises a coloration sensor for measuring a value representative of a coloration of the light. The control programs are capable of controlling the lighting generated by the lighting device as a function of the value supplied by the coloration sensor.Type: GrantFiled: December 14, 2011Date of Patent: December 29, 2015Assignee: SAINT-GOBAIN GLASS FRANCEInventors: Julien Orillard, David Nicolas

Patent number: 9091896Abstract: The invention relates to a device (1) of the electrochromic type comprising successively a substrate (2), a reflection control coating (8), a laminating interlayer (10), a functional system (4) of the electrochromic type and a substrate (2). This particular arrangement of the laminating interlayer between the reflection control coating and the functional system and the choice of the refractive index and thickness of the reflection control coating are such that the saturation values of C* in the colorimetric system (L*, a*, b*) of the device in reflection are less than or equal to 10 for angles of incidence of 60° and 8° relative to the normal (N) to the outer face (6B) of the counter-substrate and that the absolute value of the difference between the value of C* at an angle of incidence of 8° and the value of C* at an angle of incidence of 60° is less than or equal to 6.Type: GrantFiled: June 21, 2011Date of Patent: July 28, 2015Assignee: SAGE ELECTROCHROMICS, INC.Inventors: Oliver Selles, Ingolf Ripberger, Philippe Letocart, Julien Orillard
