Patent number: 10364975Abstract: A light module includes a light emitting diode (LED) array and a double-reflective assembly coupled to the LED array. The double-reflective assembly includes a lower member having a frame. The frame has an opening corresponding to the LED array. The frame and LED array are located in the same plane. The light module further includes a left bottom reflector and a right bottom reflector. The light module further includes an upper member which includes a left top reflector; and a right top reflector, wherein the left top reflector is attached to the left bottom reflector, and right top reflector is attached to the right bottom reflector, each forming an arbitrary left and right double-reflective assembly. A shape geometry and profile of each double-reflective assembly provides a pre-calculated combined non-circular asymmetrical intensity distribution pattern.Type: GrantFiled: November 3, 2014Date of Patent: July 30, 2019Assignee: BRIDGELUX INC.Inventors: Alexander Rizkin, Robert Tudhope, Vahid Moshtagh, Hannu Tapani Hukkanen, Tomi Mikael Kuntze

Patent number: 9466772Abstract: A solid-state light-emitting device (“SLD”) converting electrical energy to photon energy using a light emitter diode (“LED”) and high-temperature multi-layer optics (“HMO”) is disclosed. The SLD, in one aspect, includes a chip-on-board (“COB”), a silicone inner layer (“SIL”), and a Poly methyl methacrylate (“PMMA”) layer. The COB includes a first surface and a second surface wherein the first surface includes at least one LED. The LED converts electrical energy to optical light and the light subsequently leaves the LED becoming visible light. The SIL includes a first silicone surface and a second silicone surface wherein the second silicone surface is in contact with the first surface of COB and the second silicone surface is in contact with the PMMA layer. The operating temperature of PMMA layer is lower than the operating temperature of SIL.Type: GrantFiled: February 27, 2015Date of Patent: October 11, 2016Assignee: Bridgelux, Inc.Inventors: Robert Tudhope, Xiaolu Chen, Wenhui Zhang

Patent number: 9439299Abstract: A low-profile lighting module with light-emitting diodes (LEDs) has a water-tight seal between a molded-plastic cover and a printed circuit board (PCB). A substrate with the LEDs fits up into an indentation in the lower surface of the PCB. Landing pads on the top of the substrate attach to contact pads in the indentation that are extensions of a conductor of the PCB which is electrically coupled through the landing pads to the LEDs. A lens with a curved optical portion surrounded by a flat lip fits into another indentation on the upper surface of the PCB. A highly reflective sheet is disposed between the planar lower surface of the lens and bottom of the indentation in the upper surface. A double-sided adhesive sheet is disposed under the inside surface of the molded-plastic cover and over both the upper surface of the PCB and the flat lip of the lens.Type: GrantFiled: March 29, 2014Date of Patent: September 6, 2016Assignee: Bridgelux, Inc.Inventors: Robert Tudhope, R.
