Patent number: 10602596Abstract: Various embodiments relate to systems and methods for controlling one or more LED-based lighting sources that are coupled to a logic module by a ribbon cable. The ribbon cable allows some or all of the processing components (e.g., processors and drivers) to be decoupled from the LED-based lighting source(s). The processing components can instead be housed within the logic module, which is able to simultaneously control the LED-based lighting source(s). Together with color models established for each LED board, the logic module acts as a platform for modularity and is able to more precisely control the color channels of each LED-based lighting source using the color models established for those LED-based lighting source(s). Techniques are also described herein that allow the logic module to utilize data stored within an erasable programmable read-only memory (EPROM) that describes the color characteristics of an LED-based lighting source.Type: GrantFiled: August 20, 2018Date of Patent: March 24, 2020Assignee: Lumenetix, LLCInventors: David Bowers, Thomas Poliquin, Dustin Cochran, Matthew D. Weaver, Jay Hurley, James Kingman, Bryant Grigsby, Sanjoy Ghose

Patent number: 9353918Abstract: Light source systems and methods of operating the light source systems are disclosed. A light source system may include a combination of two lighting modules in communication with each other. The lighting modules can operate in concert, in parallel, or as master or slave. A printed circuit board assembly (PCBA) of the light source system includes electrical circuitry to drive a set of light emitting diodes (LEDs). The PCBA can include a communication interface for communication amongst the lighting modules. The PCBA can also include an optical sensor to provide color spectrum feedback to a controller module for self calibration. A master PCBA can receive sensor feedbacks, such as thermal and optical feedbacks from a slave PCBA. The sensor feedbacks can then be used to tune a color spectrum of a slave lighting module including calibrating the slave lighting module.Type: GrantFiled: March 15, 2013Date of Patent: May 31, 2016Assignee: LUMENETIX, INC.Inventors: Thomas Poliquin, Dustin Cochran, Herman Ferrier, David Bowers, James Kingman

Patent number: 9133989Abstract: A lighting system comprising multiple linear lighting module building blocks is described. A lighting module is designed to emit light in a linear configuration, and multiple lighting modules are concatenated to emit light in a single linear configuration. A mechanical coupling system allows the lighting modules to be inserted into the linear configuration from a direction perpendicular to the linear configuration. The housing of the lighting modules is designed to allow the module to be clipped together in the linear configuration.Type: GrantFiled: March 15, 2013Date of Patent: September 15, 2015Assignee: LUMENETIX, INC.Inventors: Dustin Cochran, Robert Alan Nottingham

Patent number: 9089032Abstract: Systems and methods for using an LED-based lamp for reproducing a target light are disclosed. A color-space searching technique is introduced here that enables the LED-based lamp to be tuned to generate light at a specific CCT by adjusting the amount of light contributed by each of the LED strings in the lamp. The target light is decomposed into different wavelength bands, and light generated by the LED-based lamp is also decomposed into the same wavelength bands and compared. The color-searching techniques allow the LED-based lamp to closely emulate a black body radiator given the limitations of the physical specification of color string in the LED strings.Type: GrantFiled: February 13, 2013Date of Patent: July 21, 2015Assignee: LUMENETIX, INC.Inventors: David Bowers, Thomas Poliquin, Dustin Cochran

Patent number: 8783894Abstract: A lighting system is described. The lighting system includes a lamp and a first container including a first phase change material thermally connected to the lamp. Heat generated by the lamp during operation is conducted to the first phase change material. The system also includes a second container including a second phase change material thermally connected to the lamp. Heat generated by the lamp during operation is also conducted to the second phase change material, and the second phase change material has a transition point temperature lower than the transition point temperature of the first phase change material of the first container to account for a temperature drop between the second container and the first container. The lighting system also includes a temperature sensor for reducing lamp power if the lamp becomes too hot, and a mounting bracket which may also conduct heat away from the lamp.Type: GrantFiled: February 23, 2012Date of Patent: July 22, 2014Assignee: Lumenetix, Inc.Inventors: Robert Hitchcock, James Kingman, Matthew D.

Publication number: 20140169025Abstract: A linear light module having an optical coupling element and a light pipe is described. The optical coupling element receives light emitted by multiple light emitting diodes (LEDs) having different emission wavelengths and couples the light efficiently to a linear light pipe. The light from the LEDs is efficiently mixed by the optical coupling element and the light pipe to produce a linear light output that is uniform in color and intensity. Diffusers can be used with the optical coupling element and light pipe at various locations to further enhance the uniformity of the emitted light.Type: ApplicationFiled: March 15, 2013Publication date: June 19, 2014Applicant: Lumenetix, Inc.Inventors: Matthew D.

Publication number: 20140169026Abstract: A linear light module that uses a thermally conductive housing for dissipating heat generated by a lighting source within the housing is described. Light is thermally coupled away from the lighting source via a thermally conductive heating block. The heating block is thermally coupled to a thermally conductive heat pipe that runs along the length of the housing, where the length of the housing is substantially the same length as the linear light module. The housing is extruded to include a channel that runs the length of the housing for holding the heat pipe. Because the housing is long, the heat is easily conducted from the housing.Type: ApplicationFiled: March 15, 2013Publication date: June 19, 2014Applicant: Lumenetix, Inc.Inventors: Dustin Cochran, Herman Ferrier, Sanjoy Ghose
