Patent number: 7059754Abstract: A modular automotive light device is provided. The light device may include multiple light emitting diodes (LED). Multiple light devices may be arranged in a desired manner comprising an automotive headlamp, for example. The light devices may be stacked on top of each other and/or positioned side by side to form the headlamp. Using multiple light devices provides a sufficient amount of radiated light rays in order to comply with regulations and standards for light output of light devices for use on the exterior of an automobile, for example.Type: GrantFiled: June 25, 2003Date of Patent: June 13, 2006Assignee: North American Lighting, Inc.Inventors: Matthew Andrew Lekson, Ben Wang, Dianna Lynn Stadtherr, Derek Scott Mallory, Jianzhong Jiao, Brian Curtis Wells

Patent number: 7010401Abstract: A system provides guidance to a vehicle on an approach to a position. A guidance transmitter stationed at the position includes light sources arranged in an array and a controller coupled to the light sources. The array defines a primary field-of-view (FOV) from which all light sources are visible. The light sources are divided into a plurality of sections with each section having a portion of the light sources associated therewith. Operation of each section of light sources is governed by the controller in accordance with unique cyclical on/off sequences. A primary waveform of light energy is defined by a composite of the cyclical on/off sequences visible from within the primary FOV. A plurality of secondary waveforms of light energy are defined by the cyclical on/off sequences visible from positions outside of the primary FOV.Type: GrantFiled: June 26, 2003Date of Patent: March 7, 2006Assignee: The United States of America as represented by the Secretary of the NavyInventors: Chris Richburg, Donald D. Hobden

Patent number: 6942360Abstract: An LED light engine having a high thermal conductivity substrate (e.g., a metal-clad PCB), a plurality of light-emitting-diode (LED) semiconductor devices mechanically connected to the substrate, an outer dike fixed to the substrate and surrounding at least a portion of the LED devices, and a substantially transparent polymeric encapsulant (e.g., optical-grade silicone) disposed on the plurality of LED devices and restrained by said outer dike. In one embodiment, the light engine includes a reflector (e.g., a generally conic reflector) fixed to the substrate to form the outer dike. In another embodiment, an optical component (e.g., a lens, filter, or the like) is optically coupled to the polymeric encapsulant disposed on the LED devices.Type: GrantFiled: August 23, 2004Date of Patent: September 13, 2005Assignee: Enertron, Inc.Inventors: Der Jeou Chou, Daniel Nelson, Thomas Kulaga
