Patent number: 10914890Abstract: Systems and methods for an intracanopy horticultural lighting fixture. In aspects, a horticultural luminaire has an edgelit lightguide or optical conduit extending from a housing with its major dimension extending along longitudinal axis L, and one or more endcaps coupled to respective lateral edges, endcaps being convex curved about one or more axes transverse the longitudinal axis to prevent catch points. The endcap can be coupled to the housing to hinder separation of the lightguide. In another aspect a horticultural luminaire has an edgelit lightguide generating an output having downwardly directed peaks at about +/?30 degrees from vertical. Light output is preferably batwing shaped and symmetric. Another aspect provides a method for intracanopy lighting having an entirely planar optical conduit, a major extent of the optical conduit disposed along its longitudinal axis (L), and supporting the optical conduit, preferably its entirety, below an upper plant canopy.Type: GrantFiled: October 1, 2019Date of Patent: February 9, 2021Assignee: Fluence Bioengineering, Inc.Inventor: Jonathan Becker Schmidt

Patent number: 8998473Abstract: A light reflector frame has an upper wire frame and a lower wire frame each of generally rectangular form that are spaced apart and attached at an upper peripheral edge and a lower peripheral edge by a plurality of transverse brackets. At least four of the transverse brackets have a hook formed at a top end and a bottom end such that each of the hooks opens inwardly of the upper wire frame and the lower wire frame. At least one reflective panel is disposed inwardly of at least four transverse brackets to engage the hooks with a reflective surface of each reflective panel oriented inwardly of the transverse brackets. At least two pairs of opposed transverse brackets have an extended member at the top end positioned to extend upwardly over a cover of a horticultural lamp enclosure.Type: GrantFiled: March 10, 2014Date of Patent: April 7, 2015Inventor: Terry W Anderson

Patent number: 8568009Abstract: A compact high-brightness LED aquarium light fixture is described for use in illuminating aquarium tanks artificial light. (18) The LED aquarium light uses a densely-packed array of high-brightness light emitting diodes (LEDs) that are not individually packaged, where the array behaves similarly to a point source of light. The LED chips are distributed laterally over an area, where the LED chips have light emitting surfaces for emitting light in directions transverse to said area, wherein the dimensions of the area do not exceed 25 mm. Adjacent chips of the array are preferably separated by less than about 0.2 mm. The extended point source LED array, with its lens and associated reflector, result in a concentrated light source that attractively illuminates the contents of the aquarium, and creates a desirable shimmering effect within the aquarium. A clamp-on, flexible gooseneck mounting arrangement allows for use with aquarium tanks of various sizes.Type: GrantFiled: February 8, 2011Date of Patent: October 29, 2013Assignee: Dicon Fiberoptics Inc.Inventors: Brian I-Yuan Chiang, Junying Jonathan Lu, Ho-Shang Lee

Patent number: 8308332Abstract: A system for illuminating a sports field covered with turf. The system includes: a plurality of light arrays configured to be positioned in a spaced-apart manner under a portion of the turf and oriented to emit light upwards through the turf; and a control system for selectively controlling activation of the light arrays to provide illuminated markers on the sports field.Type: GrantFiled: February 10, 2012Date of Patent: November 13, 2012Inventor: Lyle Suhr

Patent number: 8299445Abstract: Disclosed is a lighting device for use in the control of a plant disease, which has a light source capable of emitting light containing ultraviolet ray. The light source can emit both of UV-B having a wavelength component with a wavelength of about 280 to 340 um and UV-C in which a wavelength component with a wavelength of about 255 nm or less is cut off from wavelength components with wavelengths of about 100 to 280 nm to plant in a superimposed manner. The irradiation of a plant with the UV-C and the UV-B ensures to further inhibit the spore formation or the hypha growth of a filamentous fungus that causes a disease or the like, and to induce a resistance against a disease in the plant.Type: GrantFiled: July 16, 2008Date of Patent: October 30, 2012Assignee: Panasonic CorporationInventors: Makoto Yamada, Osamu Kuramitsu, Masaki Ishiwata

Patent number: 7278752Abstract: A small light source for internally illuminating live flowers and other products is formed in the shape of a pin with a battery case operatively connected to the light source. A sharp penetrating tip surrounds the light source and is fixed to a rigid tube for manipulating the device to insert the light source within the structure of the plant. The device is of such a size that it can be supported by a plant without deformation of the plant.Type: GrantFiled: March 9, 2005Date of Patent: October 9, 2007Assignee: Chemical Light Inc.Inventors: William R. Palmer, Stephen L. Palmer, Robert N. Palmer

Patent number: 7073932Abstract: A decorative assembly for use within a floral arrangement includes a plurality of optical fibers, a plurality of light emitting diodes, a base portion, and a power source. The optical fibers each have first and second ends. The light emitting diodes are coupled to the first end of each of the optical fibers for illuminating the optical fibers. The base portion houses the lighting emitting diodes and at least a portion of the optical fibers. The power source is coupled to the light emitting diodes through an optional light driving circuit. The optical fibers are illuminated such that the light emitted at the second end of the optical fibers creates an aesthetically decorative effect within the floral arrangement.Type: GrantFiled: July 30, 2004Date of Patent: July 11, 2006Inventor: Harry Lee Wainwright

Publication number: 20040190284Abstract: A decorative optical fiber artificial plant has a base and an artificial foliage arrangement. The base has a housing and a colored light generator mounted in the housing. The artificial foliage arrangement is composed of multiple optical fibers and is connected to a specific position of the housing on which colored lights shines. The colored light generator has multiple LEDs and a controller to drive the LEDs. The controller has at least a microprocessor and multiple electronic switches connected between output ports of the microprocessor and the corresponding LEDs. Further, different driving programs are built into the microprocessor so the colored light generator can generate different color lights with various characteristics.Type: ApplicationFiled: March 31, 2003Publication date: September 30, 2004Inventor: Chen-Sheng Yang
