Patent number: 11913634Abstract: Apparatus and methods for enhanced lighting. The apparatus may include a light-transmitting body. The apparatus may include a light projector. The projector may be configured to propagate into the light-transmitting body an incoming incoherent light. The projector may be configured to propagate into the light-transmitting body an incoming visible coherent light. Emerging coherent light within a visible wavelength rage attributable to the incoming visible coherent light may have a first intensity. The first intensity may be greater than a second intensity. The second intensity may be an intensity of any emerging coherent light that is within the wavelength range and is attributable to the incoming incoherent light. Emerging light may be light that emerges from the light-transmitting body.Type: GrantFiled: May 5, 2022Date of Patent: February 27, 2024Assignee: Wangs Alliance CorporationInventors: Shelley S. Wald, Wai Ho Choy, Derrick A. Wald

Patent number: 11696970Abstract: Apparatus, methods and instructions for disinfecting air. The apparatus may include, and the methods may involve, a fixture. The fixture may include a germicidal light source. The fixture may include a fan. The fan may circulate air through a volume into which the germicidal light source propagates germicidal light. The light source may be configured to emit, upward from a horizontal plane, a beam that, absent reflection off an environmental object, does not cross the horizontal plane. The apparatus may include a shield that prevents light from the light source from crossing the horizontal plane. The sensor may face upward from the horizontal plane. The sensor may face downward from the horizontal plane.Type: GrantFiled: November 24, 2022Date of Patent: July 11, 2023Assignee: Wangs Alliance CorporationInventors: Shelley S. Wald, Voravit Puvanakijjakorn, Rong Feng Yu, David Xin Wang, Li Changyong, Zhou Tingting
