20090273297 | POWER FACTOR CORRECTION AND DRIVER CIRCUITS - Power factor correction and driver circuits and stages are described. More particularly, power factor correction circuits are described that utilize an auxiliary inductor winding for power regulation. Driver circuits configured for electrical loads such as series arrangements of light emitting diodes are also described. An exemplary embodiment of a driver circuit can implement a comparator and/or a voltage regulator to allow for improved output current uniformity for high-voltage applications and loads, such as series configurations of LEDs. Embodiments of PFC stages and driver stages can be combined for use as a power supply, and may be configured on a common circuit board. Power factor correction and driver circuits can be combined with one or more lighting elements as a lighting apparatus. | 11-05-2009 |
20090261746 | CONTROL OF LIGHT INTENSITY USING PULSES OF A FIXED DURATION AND FREQUENCY - A method and circuit to control the intensity of lights, illumination fixtures, and displays using pulses of a fixed duration and a fixed frequency (FD/FF) is provided. In particular, the method may be used to control one more light sources. By varying the number of pulses in a control burst, the total current flowing through the light source may be precisely controlled providing greater accuracy than other methods, such as, for example, PWM or variable pulse frequency. The FD/FF technique may be used in conjunction with any number of light sources, and finds particular application in LED displays and for any type of LED illumination fixture. | 10-22-2009 |
20090109689 | REFLECTOR - A metallic reflector device having one or an array of individual reflector elements for positioning over a corresponding one or array of light sources, preferably comprising one or more light emitting diodes (LEDs). The metallic reflector device includes a planar base and a plurality of the reflector elements. The planar base has one or a plurality of apertures, each aperture having an edge that defines a proximal rim of the reflector element. Each reflector element includes an annular sidewall having an inner surface that extends from the proximal annular rim to a distal annular rim. The proximal annular rim defines a first opening through which direct and reflected light from a light source is emitted. The distal annular rim defines a second opening through which the light source is disposed. The inner surface of the annular sidewall is formed from the material of the planar sheet by mechanically deforming the planar sheet, such as by stamping or drawing. | 04-30-2009 |
20090109670 | ADJUSTABLE LIGHTING APPARATUS - A lighting apparatus having a pivotable light cartridge for positioning and directing the light output of a plurality of light sources, the light cartridge including an elongated base oriented along the longitudinal axis, a pivot at the opposed first and second ends of the light cartridge along the longitudinal axis, a plurality of light sources, and an longitudinal wall extending from the lateral edge of the base, the wall including a plurality of spaced-apart, radially-extending ribs, each having a distal edge. A rotatable worm gear having a helical thread is positioned in mechanical engagement with a portion of the distal edges of the plurality of ribs, so that rotation of the worm gear with a hand tool effects pivoting of the light cartridge along the longitudinal axis. | 04-30-2009 |
20090103299 | OPTIC POSITIONING DEVICE - A device for holding and positioning an optic, such as a refractive lens, over a light source such as a light emitting diode. The refractive lens is frustum-shaped with an upper light-exiting end having an upper rim, a lower light-entering end, and a conical sidewall that tapers from the upper rim to the lower end. The device has a channel including a base and first and second sidewalls extending from the opposed side edges of the base, and further having one or more optic holding positions. The optic holding position includes an aperture formed in the base that is configured to receive the conical sidewall of the optic, and an aperture formed in a portion of each sidewall, adjacent the aperture in the base, for retaining a portion of the upper rim of the optic lens. The aperture can include a slot opening through which a portion of the upper rim of the optic lens at least partially extends. | 04-23-2009 |
20090031601 | Adjustable Menu Panel - A menu panel for supporting elongated menu strips of varying heights is disclosed having adjustable guide rails supported by a frame. The frame includes vertical side frame members incorporating guide rail locating elements disposed along the length of the vertical side frame members to position the guide rails. The guide rails are selectively positionable along the length of the vertical side frame members to provide adjustable spacing between adjacent pairs of guide rails. The menu strips include descriptive indicia such as product names and pricing information and are disposed between and supported by adjacent pairs of the guide rails. | 02-05-2009 |
20090021939 | Lighted architectural mesh - A lighted architectural mesh includes a plurality of interconnected wires forming a plurality of transverse openings. At least one light element is slidably received within at least one of said transverse openings. The at least one light element includes light nodes emitting light through the interstices on the front and/or rear side of the architectural mesh. The at least one light element further comprises a plurality of connecting elements, wherein the light emitter nodes of the at least one light element are releasably interconnected in series by the connecting elements. | 01-22-2009 |
20080278956 | Lamp Device and Method to Retrofit a Lighting Fixture - A device and method for retrofitting a light fixture from use with a lamp socket that employs an incandescent or metal halide lamp, to use with another lamp assembly. The lamp fixture has a collar with a base and an annular outer wall extending out from the base. The LED lamp device includes a neck base having an annular outer wall having a shaped outside surface that is placed into direct surface contact with the inner surface of the annular outer wall of the collar, to establish an effective heat-transferring interface. The shaped outer surface of the neck base provides proper fitting of the LED lamp device into the lighting fixture, and provides a heat-transferring interface over substantially all of the outer surface of the neck base, to dissipate heat away from the LED module. Aluminum material provides high thermal conductivity, light weight, availability, and low cost. | 11-13-2008 |
