Patent number: 10663127Abstract: A thin profile surface mount LED lighting apparatus includes a housing, an LED board including multiple LEDs, and a lens. The lens has a back side facing the LED board and a front side that provides a downward facing surface when the LED lighting apparatus is installed in an opening of a ceiling. The lens is disposed with respect to the LED board such that the LEDs illuminate the back side of the lens. A first spacing of the LEDs causes resulting light from the downward facing surface of the lens to be substantially uniform during operation of the apparatus. In one example, a thin front edge of a sidewall of the housing, forming a perimeter around the lens, is flush with the lens and is appreciably thin (e.g., a thickness of less than three millimeters), and a depth of the sidewall housing is less than one inch.Type: GrantFiled: October 15, 2019Date of Patent: May 26, 2020Assignee: DMF, Inc.Inventors: Michael D.

Patent number: 9880417Abstract: A light-emitting apparatus having a 16:9 geometry includes light-emitting elements disposed on a first substrate or a second substrate, light flux control members respectively disposed on the light-emitting elements and on the first or second substrate, and a film stack disposed above the light flux control members. Each light flux control member includes a bottom surface section disposed on the first or second substrate, a non-rotationally symmetric input surface section having an inward recess disposed in the bottom surface section at a position directly above one of the light-emitting elements, and a non-rotationally symmetric output surface configured to refract light passing through the input surface section, and to transmit light outside. The light flux control members disposed on the first substrate are spaced 100 mm apart from each other in a first direction, and the light-emitting elements are spaced 23 mm away from the film stack.Type: GrantFiled: November 17, 2015Date of Patent: January 30, 2018Assignees: Seoul Semiconductor Co., Ltd., InteLED Corp.Inventors: Mark Jongewaard, William A.

Patent number: 9784432Abstract: An optical assembly includes a first reflector having a reflective surface with a first lateral extent, and a second reflector having a reflective surface with a smaller, second lateral extent. The second reflector is disposed such that the second reflective surface opposes the first reflective surface with a space therebetween. A light emitter couples with the first reflector such that the light emitter emits light along a central axis, away from the first reflector and toward the second reflector. A translucent diffuser substantially spans the space between the first and second reflectors. A majority of the light emitted by the light emitter reflects from the first and second reflectors, and impinges on and passes through the diffuser. A luminaire that includes the optical assembly also includes an outer shell having a form that is analogous to a shape of the diffuser of the optical assembly.Type: GrantFiled: May 21, 2015Date of Patent: October 10, 2017Assignee: ABL IP Holding LLCInventors: Robert T.

Patent number: 8723146Abstract: Micro-channel-cooled UV curing systems and components thereof are provided. According to one embodiment, a lamp head module includes an optical macro-reflector, an array of LEDs and a micro-channel cooler assembly. The array is positioned within the reflector and has a high fill factor and a high aspect ratio. The array provides a high irradiance output beam pattern having a peak irradiance of greater than 25 W/cm2 at a work piece surface at least 1 mm away from an outer surface of a window of the reflector. The micro-channel cooler assembly maintains a substantially isothermal state among p-n junctions of the LEDs at less than or equal to 80° Celsius. The micro-channel cooler assembly also provides a common anode substrate for the array. A thermally efficient electrical connection is formed between the array and the common anode substrate by mounting the array to the micro-channel cooler assembly.Type: GrantFiled: January 4, 2013Date of Patent: May 13, 2014Assignee: Heraeus Noblelight Fusion UV Inc.Inventors: Jonathan S.
