Patent number: 9696318Abstract: The present invention provides a hydrophilic film that causes a liquid to diffuse rapidly in a single direction. The hydrophilic film comprises a substrate having a texture of parallel sunken and raised patterns, and a hydrophilic coat comprising a coat of silicon dioxide particles. The present invention also provides a method for preparing the hydrophilic film. The method comprises: preparing an aqueous dispersion of silicon dioxide particles, wherein the average size of the silicon dioxide particles is 1 to 60 nm, and the concentration of the silicon dioxide particles is 0.05% to 15% by weight; coating the aqueous dispersion of silicon dioxide particles on a substrate, wherein the substrate has a texture of parallel sunken and raised patterns; and drying the substrate coated with the aqueous dispersion of silicon dioxide particles.Type: GrantFiled: September 12, 2013Date of Patent: July 4, 2017Assignee: 3M Innovative Properties CompanyInventors: Te-Wei Chen, Huang Chin Hung, Naiyong Jing

Patent number: 9625123Abstract: Lens assemblies for use in remote phosphor lighting systems, and methods of making and using them, are described. The lens assemblies typically include a lens member, a dichroic reflector attached to an outer surface of the lens member, and a phosphor layer attached to an inner surface of the lens member. The dichroic reflector reflects LED light originating from a given source point in a reference plane proximate the inner surface to a given image point in the reference plane. The phosphor layer may be patterned to cover one or more first portions of the inner surface and to expose one or more second portions, and/or the phosphor layer may be removably bonded to the inner surface. The lens assemblies can be readily combined with one or more short wavelength (e.g. blue) LEDs and other components to provide a remote phosphor lighting system.Type: GrantFiled: June 14, 2012Date of Patent: April 18, 2017Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Andrew J. Ouderkirk, Ravi K. Sura, Nicholas T. Gabriel, Huang Chin Hung
