  • Publication number: 20210010647
    Abstract: An LED downlighting apparatus includes a housing with a sidewall having a front facing edge and a back facing edge positioned adjacent to a ceiling when the LED downlighting apparatus is installed in an opening of the ceiling. A depth of the sidewall is less than one inch and a thickness of at least a portion of the sidewall is less than three millimeters. An LED board and a lens are coupled to the housing. The lens is disposed with respect to the LED board such that the lens is illuminated from a back side. One or more mechanical couplers snap fit the apparatus to a junction box installed and positioned above the ceiling such that when the apparatus is snap fit to the junction box through the opening of the ceiling, the housing appears to be surface mounted to the ceiling.

  • Patent number: 10663127
    Abstract: 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.

  • Patent number: 9880417
    Abstract: 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.

  • Patent number: 9784432
    Abstract: 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.

  • Patent number: 9255695
    Abstract: Exemplary embodiments of the present invention relate to an illumination lens disposed over a light-emitting diode (LED). The illumination lens includes an internal surface surrounding the LED and configured to intercept light emitted by the LED, wherein the internal surface comprises an arch-shaped non-rotationally symmetric, elongated horizontal cross-section. The illumination lens also includes an external surface comprising a central cusp, the external surface extending laterally with non-axially-symmetrical profiles in different horizontal directions, the non-axially-symmetric profiles being elliptical with respect to a tilted major axis of the illumination lens, wherein the light-emitting device is configured to produce an elongated illumination pattern.

  • Patent number: 8723146
    Abstract: 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.
