|20150312976||Low Power Bypass Circuit for LED Open Circuit and Reverse Polarity Protection - A low power bypass circuit for use with a string of series-connected LEDs includes a semiconductor diode and resistor connected in series, which semiconductor diode and resistor combination become conductive upon the failure of an LED or upon the improper, reverse polarity connection of the string of series-connected LEDs to a power supply. When the semiconductor and resistor combination becomes conductive, a three-terminal gate-controlled semiconductor switching device becomes conductive, thereby bypassing the failed LED and protecting the integrity of the string of series-connected LEDs upon the improper reverse polarity connection of the string of series-connected LEDs to a power supply.||10-29-2015|
|20150308642||Self-Aiming Track Light Fixture System and Method - A camera, a mechanical movement system and a video control board are used to locate a recognizable light source on a stationary or moving object to be illuminated. Once the recognizable light source is recognized by the camera, the video control board provides instructions to the mechanical movement system to move the light output from the source of illumination in a track light fixture assembly to the location of the recognizable light source.||10-29-2015|
|20150308631||Retrofit System and Method for Replacing Linear Fluorescent Lamp with LED Modules - A system for replacing linear fluorescent lamps with LED modules in a cabinet sign includes an LED module support structure. The LED module support structure may be attached to the raceways of the cabinet sign or to the sockets formerly used for mounting fluorescent lamps between the raceways.||10-29-2015|
|20150262518||LED Light Engine for Signage - A durable LED light engine includes a printed circuit board including LEDs mounted thereon positioned between a substantially U-shaped top enclosure and a bottom enclosure. Once assembled together using alignment holes and projections, the combination of the substantially U-shaped top enclosure, the printed circuit board and the bottom enclosure are held together with a molding material.||09-17-2015|
|20130155672||REMOTE CONTROL TRACK LIGHT FIXTURE - A track head unit includes a lighting device, a first sensor, a second sensor, one or more motors, and a controller. The first sensor is configured to receive transmissions from a portable remote control device. The second sensor is configured to receive transmissions associated with a target object. The one or more motors are mechanically coupled to the lighting device and is configured to position the lighting device along a first direction and a second direction. The controller is coupled to the lighting device, the first sensor, the second sensor, and the one or more motors. The controller is configured to receive a control signal from the remote control device via the first sensor, responsively transmit a locator signal to a locator that is disposed at a target object, receive a response signal via the second sensor from the remote object in response to the transmitting, and based upon the response signal, actuate the motors to aim the lighting device at the target object.||06-20-2013|
|20090251882||LIGHT-EMITTING DIODE ILLUMINATION STRUCTURES - Illumination device embodiments are provided which include a transparent bulb that carries at least one phosphor. A redirector is positioned within the bulb and at least one light-emitting diode (LED) is positioned over the redirector to be energized and emit light that excites the phosphor. The redirector helps to diffuse the resultant mix of LED-emitted light and phosphor-emitted light that issues from the device. The redirector also provides a heat path away from the LEDs. In a device embodiment, LEDS form first and second diode groups that have emission peaks in different regions. Selectively energizing these groups alters the color temperature of the device's light. Energizing both groups and varying currents of each group also alters the color temperature of the device's light. In other device embodiments, the redirector has a portion outside the bulb which may also define protuberances that enhance heat radiation. In yet other device embodiments, each LED may have an associated phosphor. Some embodiments may be further enhanced by the further addition of a phosphor to the bulb.||10-08-2009|
