Publication number: 20160305638Abstract: A light emitting diode (LED) module having a configurable LED substrate capable of receiving varying numbers and layouts of LEDs are described herein. The LED substrate includes LED coupling points for receiving the LEDs and electrical traces etched into the substrate for routing power to the LEDs. The LED module can include a multi-LED over-optic having multiple over-optics that are configured to match the number and configuration of the LEDs positioned on the substrate. The LED coupling points and over-optics can be arranged symmetrically to enable the LED module to be rotated to adjust the light output distribution and direction. The LED module can include a power connection mechanism, for example located at the center of the substrate, that also allows the LED module to be rotated. One or more of the LED modules may be mounted on a heat sink and incorporated into a light fixture.Type: ApplicationFiled: June 24, 2016Publication date: October 20, 2016Inventors: Anthony James Carney, Chun Wah Chan, Gregg Arthur Lehman, Ellis Patrick, Christopher Ladewig, Timothy Glen Wright, Christopher Michael Bryant, Victor Diegues

Patent number: 9429298Abstract: A light fixture includes a fixture housing and at least one adjustable lighting head assembly coupled thereto. Each lighting head assembly includes a lighting head and a mounting assembly that couples the lighting head to the fixture housing. The lighting head includes a housing, a light source inserted therein, a cover coupled to the distal end of the housing, and an optic lens rotatably disposed between the housing and the cover which produces an asymmetric light output. The mounting assembly includes a rotatable mounting base, a pin head, and a pin extending from the mounting base to the pin head. The pin is inserted through a slot formed within the housing and the pin head slides within the housing along the length of the slot. Hence, the asymmetric light output is adjustable using the rotation of each of the optic lens, the sliding pin head, and the rotatable mounting base.Type: GrantFiled: March 14, 2013Date of Patent: August 30, 2016Assignee: Cooper Technologies CompanyInventors: Westly Davis Hetrick, Christopher Ladewig

Patent number: 9109774Abstract: Systems, methods, and devices for reducing glare or pixilation associated with LEDs are disclosed. The disclosure relates to a light module that includes a cover panel that reduces contrast in the light emitted by LEDs. The cover panel can be mounted on a substrate which can include a plurality of LEDs. Apertures in the cover panel are aligned each of the LEDs and any optic that may be disposed over each LED. A first portion of the light emitted from the LEDs passes through the optic only and into the environment to be illuminated. A second portion of the light emitted from the LEDs passes through both the optic and the cover panel before passing into the environment to be illuminated. The cover panel can be diffuse and can include various characteristics including textures, objects, and angled surfaces that assist in scattering light.Type: GrantFiled: July 20, 2012Date of Patent: August 18, 2015Assignee: Cooper Technologies CompanyInventors: Philip Dean Winters, Hung Dinh, Reed Alan Bradford, Sylvia Herman, Christopher Ladewig

Publication number: 20150062911Abstract: A multi-functional heat sink includes a top portion and a skirt portion extending down from the top portion. When a light source is attached to the top portion on an underside of the multi-functional heat sink, the skirt portion reduces risk of rain water from reaching the light source and prevents light emitted by the light source from exiting the multi-functional heat sink in an upward direction. The multi-functional heat sink is made from sheet metal.Type: ApplicationFiled: August 27, 2014Publication date: March 5, 2015Inventors: Philip Dean Winters, Christopher Ladewig

Patent number: 8845141Abstract: A reflector is rotatably coupled to a light emitting diode (LED) module assembly. The reflector includes multiple alignment features that correspond with multiple notches provided in a reflector attachment coupled to a LED light source. The reflector can be made of a non-conductive substrate material, such as glass, and can have a non-conductive, reflective coating deposited on the inner surface of the reflector to allow the reflector to be more closely positioned to the LED light source. Reflector attachments can help to maintain precise reflector position during coupling with the LED light source. Media holders can be removably coupled to the light emitting portion of the reflector and provide for the quick mounting and placement of one or more optical media in the light path output by the reflector.Type: GrantFiled: May 8, 2012Date of Patent: September 30, 2014Assignee: Cooper Technologies CompanyInventors: Grzegorz Wronski, Steven Pyshos, Oliver Ernst, Christopher Ladewig, Gregg Arthur Lehman

Patent number: 8764220Abstract: A linear light emitting diode (“LED”) light fixture includes LED modules that interface with one another to provide a substantially continuous array of LED's. This continuous array allows for substantially uniform light output from the LED light fixture. The LED modules can interface with one another via one or more connectors, which allow two or more LED modules to be electrically and mechanically coupled together. The connectors may be disposed beneath the LED's so that the connectors are not visible when the LED modules are coupled together. The connectors may be disposed along opposite ends of the modules to allow for end-to-end configurations of the modules and/or along side ends of the modules to allow for angled or curved configurations of the modules. The LED modules can be powered via one or more wires, magnets, or clips, which are coupled to a power source.Type: GrantFiled: April 27, 2011Date of Patent: July 1, 2014Assignee: Cooper Technologies CompanyInventors: Chun Wah Chan, Anthony James Carney, Jerold Alan Tickner, Peter J Menard, Christopher Ladewig, Valerica Grigore, Bradley Stephen Garrett, Travis William Francis Boyle

Publication number: 20120002411Abstract: A troffer-style luminaire includes first and second side ends and a top end extending between the side ends. The side and top ends define an interior region. Light emitting diodes (“LEDs”) are coupled along interior surfaces of the side ends, within the interior region. At least some of the LEDs are coupled to the interior surfaces by being wedged between members protruding into the interior region from the interior or other surfaces. In addition, or in the alternative, one or more spring clips can apply a force that holds the LEDs against the interior surfaces. A reflector extends between the LEDs and the top member and reflects light from the LEDs towards a bottom end of the frame. The light emitted by the LEDs is directed to the reflector and then indirectly emitted through the bottom end, into a desired environment.Type: ApplicationFiled: September 14, 2011Publication date: January 5, 2012Applicant: Cooper Technologies CompanyInventor: Christopher Ladewig

Patent number: 8084686Abstract: The power box can be stacked while limiting horizontal translation. The power box includes an electrical component box, a cover for the electrical component box, and a support assembly. The support assembly has feet that raise the electrical component box off of the ground. The cover includes one or more raised projections that restrict the horizontal translation of a power box positioned thereon, by dimensioning the projections apart by a distance slightly greater than an exterior width of the support assembly of the power box that rests upon the cover. Horizontal translation is further limited by dimensioning the feet such that, when placed on top of another power box, the interior dimension between two feet is slighting greater than the dimension of the cover. So, when the top power box attempts to slide, the feet of the top power box contact the cover of the bottom power box.Type: GrantFiled: May 29, 2009Date of Patent: December 27, 2011Assignee: Cooper Technologies CompanyInventors: Christopher Ladewig, Matthew William Conger
