Patent number: 11698174Abstract: A device for day lighting the interior of structure deploys reflective louvers that are spaced apart in stacks. The louvers include a coating or multilayer structure that is operative to reflect visible light but transmit IR light through the louver. The louvers also have a retro-reflective structure to return the IR light by reverse reflection in the opposite direction of the incident light, which is back toward the sun. The interior of the structure is more uniformly illuminated with visible light while the louvers and interior are not heated by IR light or radiation from the sun.Type: GrantFiled: January 27, 2022Date of Patent: July 11, 2023Assignee: SERRALUX INC.Inventor: Mark E Gardiner

Patent number: 11248763Abstract: A external light control device for equatorially located building utilizes tilting external light shelves that are capable of tilting backward (toward the building) from a vertical orientation to reflect low am (or late pm) sun away from occupants, but are deployed at a tilt away from the building exterior to capture more sun closer to noon time. The structure preferably integrate IR rejecting coating for incident light which is re-directed by TIR surface disposed normal to the thin film layers in a multi-layer IR reflective coating. The panel may be monolithic or comprise tilting louvers, which can be metallic, dielectric, or TIR reflectors. The louvers preferably also tilt in response to the determined sun position with the panel to optimize light utilization.Type: GrantFiled: June 16, 2020Date of Patent: February 15, 2022Assignee: SERRALUX INC.Inventor: Mark E Gardiner

Patent number: 11156027Abstract: Exposed edge margins that are formed when a window film is installed on a glazing surface using an aqueous fluid as a lubricant are immediately covered by a series of elongated members that adhere to one or more of the window film or the surrounding frame. The elongated members provide concealed gaps or channels that allow for the slow evaporation of the aqueous fluid as the adhesive on the window film slowly wets and develops maximum bond strength to the glazing surface. The elongated members are preferably left in place as an inner frame. The inner frame device and method can be deployed in attached an light control film to a window, such as UV protective film, IR rejecting film, absorbing film and daylighting film.Type: GrantFiled: November 19, 2019Date of Patent: October 26, 2021Assignee: SerraLux Inc.Inventor: Robert Somers Ford

Patent number: 10677405Abstract: A high efficiency daylight directing structure for application on fenestration deploys closely spaced macroscopic bars of transparent resin to eliminate different forms of glare. The spaced apart surfaces provide for efficient reflection of selective incident light, by TIR or metallic surfaces, via the ultra-smooth native surfaces from a mold or casting process. A close spacing is readily obtained in various attachment methods to boost efficiency. The fabrication method allows selective deposition of absorbing layers, such as by of painting/printing between alternating native optical surface to provide one way transparency at high angles of incidence. The bars are supported on at least one common planar surface by transparent support member with an optical quality adhesive material filling any imperfection in the bars common planar surface that form in fabrication.Type: GrantFiled: October 31, 2017Date of Patent: June 9, 2020Assignee: SERRALUX INC.Inventor: Mark E Gardiner

Patent number: 10538959Abstract: An automated ganged louver assembly is adjusted in orientation by an actuator in the louver header that suspends or supports the louver rotation mechanism. The actuator is energized in response to a determination of solar elevation, which is optionally from a light sensor output via a controller. The light sensor employs an optical element to detect at least one of the sun elevation and azimuth, as well as general exterior light levels. The solar elevation and azimuth can also be determined by calculations from the window orientation and latitude. The optical elements and the controller are coupled to at least one of the louvers or the louver header to provide a self contained system that does not require exterior power or controls, unless desired.Type: GrantFiled: September 10, 2015Date of Patent: January 21, 2020Assignee: SERRALUX INC.Inventors: Mark E Gardiner, David Allen Lockett, Robert Somers Ford

Patent number: 10458610Abstract: A generally plano rectangular louvers are capable of being ganged in a stacked tiltable array to enhance light re-direction when titled to follow the solar elevation. Combinations of features and optical characteristic avoid optical artifacts and enhance efficiency of light utilization and manufacturing. Different louvers can be combined in alternative ways in such arrays. Light directly louvers, films, sheets and panels deploy a grooves that re-direct exterior sunlight for deeper penetration into rooms and building interiors. Absorbing structure are combined with films or panel that while reducing total interior illumination, reduce the potential for annoying glare at low solar elevations.Type: GrantFiled: December 23, 2018Date of Patent: October 29, 2019Assignee: SerraLux Inc.Inventor: Mark E Gardiner

Patent number: 8873146Abstract: Attachment methods for daylighting sheets and a resulting optical construction enable daylighting microstructures to be secured to a light incident surface, such as a glazing. Applying an adhesive to selected portions of the daylighting microstructures creates a transparent, optical adhesive surface that enables the daylighting microstructures to be oriented outward, facing the incident light, and effectively seals the microstructures against the glazing to prevent ingress of dust and contaminants that would degrade optical efficiency.Type: GrantFiled: November 9, 2012Date of Patent: October 28, 2014Assignee: SerraLux Inc.Inventor: Mark E.
