| 20110273098 | Reduction of Harmonic Distortion for LED Loads - Apparatus and associated methods reduce harmonic distortion of a excitation current by diverting the excitation current substantially away from a number of LEDs arranged in a series circuit until the current or its associated periodic excitation voltage reaches a predetermined threshold level, and ceasing the current diversion while the excitation current or voltage is substantially above the predetermined threshold level. In an illustrative embodiment, a rectifier may receive an AC (e.g., sinusoidal) voltage and deliver unidirectional current to a string of series-connected LEDs. An effective turn-on threshold voltage of the diode string may be reduced by diverting current around at least one of the diodes in the string while the AC voltage is below a predetermined level. In various examples, selective current diversion within the LED string may extend the input current conduction angle and thereby substantially reduce harmonic distortion for AC LED lighting systems. | 11-10-2011 |
| 20110241559 | INTEGRAL CONDUIT MODULAR LIGHTING - Apparatus and associated methods involve a light module adapted to mount to an open face of a conduit body. In an illustrative example, the light module may include an electrical interface for making operative electrical connection to conductors disposed within the conduit body. In some particular embodiments, the electrical interface may include an insulation displacement-style connector to facilitate installation and/or removal of the light module. In various examples, the conduit body may substantially conform to a form factor of a conduit body for a conventional conduit system. | 10-06-2011 |
| 20110228515 | Light Sources Adapted to Spectral Sensitivity of Diurnal Avians and Humans - Various apparatus and associated methods involve a light source that provides light at wavelengths that substantially correlate to local maxima in the spectral sensitivity of a diurnal avian. In an illustrative example, the light source may output light primarily in wavelength bands that are not substantially absorbed by colored oil droplets and/or visual pigment in at least one type of cone in the eye of a diurnal avian. In some embodiments, the light source may include a light-emitting diode (LED) light source. Exemplary light sources may output spectral components to illuminate diurnal avians with local maxima of intensity at wavelengths that substantially correspond to local maxima in a spectral sensitivity visual response characteristic of the diurnal avians. | 09-22-2011 |
| 20110210678 | Spectral Shift Control for Dimmable AC LED Lighting - Apparatus and associated methods involve operation of an LED light engine in which a relative intensities of selected wavelengths shift as a function of electrical excitation. In an illustrative example, current may be selectively and automatically diverted substantially away from at least one of a number of LEDs arranged in a series circuit until the current or its associated periodic excitation voltage reaches a predetermined threshold level. The diversion current may be smoothly reduced in transition as the excitation current or voltage rises substantially above the predetermined threshold level. A color temperature of the light output may be substantially changed as a predetermined function of the excitation voltage. For example, some embodiments may substantially increase or decrease a color temperature output by a solid state light engine in response to dimming the AC voltage excitation (e.g., by phase-cutting or amplitude modulation). | 09-01-2011 |
| 20110193467 | Modular Architecture for Sealed LED Light Engines - Apparatus and associated methods involve an assembly of multiple LED light engines in which a desired number of LED lamps are mounted to a plate that forms a wall of an enclosure. In an illustrative example, three LED light engines may be mounted to a plate that may be slidably installed as a wall of an extruded housing that contains electrical connections from an AC power inlet to each light engine. In various examples, the number and layout arrangement of the LED light engines may be custom selected for a particular application. | 08-11-2011 |
| 20110109244 | ARCHITECTURE FOR HIGH POWER FACTOR AND LOW HARMONIC DISTORTION LED LIGHTING - Exemplary apparatus and associated methods involve a bypass module for modulating conductivity of one or more current paths to provide a first set of LEDs that are conducting near minimum output illumination and having a larger conduction angle than that of a second set of LEDs that conduct at a maximum output illumination. In an illustrative example, the conductivity of a bypass path in parallel with a portion of the second set of LEDs may be reduced while the AC input excitation is above a predetermined threshold voltage or current. The bypass path may be operated to provide a reduced effective turn-on voltage while the input excitation is below the predetermined threshold. For a given maximum output illumination at a maximum input excitation, the bypass module may control current through selected LEDs to construct an input current waveform with substantially improved power factor and reduced harmonic distortion. | 05-12-2011 |
| 20110101883 | LED LIGHTING FOR LIVESTOCK DEVELOPMENT - Apparatus and associated methods involve a hangable LED light assembly constructed to provide a selected color output illumination as a function of excitation intensity. In an illustrative example, the color output may be selected to promote biological development throughout livestock development stages (e.g., incubation, growth, and reproduction). The light intensity may controllable, for example, in response to a light dimmer arranged to modulate AC excitation applied to the LED downlight. As the light intensity is decreased in response to a simple dimmer control, the spectral output of the LED downlight may shift its output wavelengths. Accordingly, some exemplary installations may provide controlled combinations of intensity and color to substantially optimize lighting conditions for livestock. | 05-05-2011 |
| 20110050133 | LED Lamps with Packaging as a Kit - Apparatus and methods for re-usable packaging of a lighting product include providing a container body to receive an electric lamp and a cover that can be repeatedly sealed and unsealed to the container. In an illustrative example, the lamp may be an AC LED lamp substantially located within the container body by a lamp locating feature on a bottom interior surface of the container body. In some embodiments, an interior surface of the lid may provide a projecting feature configured to positively retain the lamp in the lamp locating feature when the lid is installed on the container body. In various embodiments, the container body and the container lid may advantageously provide a protective package that may be sold as a kit, and may further provide a durable and reusable general purpose container system that may, for example, substantially reduce an environmental footprint associated with lamp packaging. | 03-03-2011 |
| 20100207150 | Light Emitting Diode Assembly and Methods - Exemplary systems and methods for LED light engines include an LED package with electrical leads, each lead forming a compliant portion for making electrical and mechanical connection upon insertion into a receptacle of a circuit substrate. In an illustrative example, the electrical and mechanical connections may be formed upon the insertion of the compliant portion into the receptacle and without further process steps involving solder. Various examples may further include an elongated thermal dissipation member extending from a bottom of a package that contains the LED, where the elongated thermal member (e.g., tab) may be in substantial thermal communication with the LED die. As an example, the tab may provide a substantially reduced thermal impedance for dissipating heat from the LED die. Upon insertion into a circuit substrate, the LED package may be releasable by mechanical extraction without applied heat to facilitate repair or replacement, for example. | 08-19-2010 |
