Abstract: 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.

Abstract: 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, the combination of the substantially U-shaped top enclosure, the printed circuit board and the bottom enclosure are held together with a molding material.

Abstract: A method for assembling and contacting an illuminant comprising one light emitting diode, having a support element on which the light emitting diode is arranged having passage openings in the electrical contact region of a cable and preferably in the vicinity of a cable. The method comprises contacting the cable with the support element and applying a hot melt adhesive to the cable and the support element; and thereby mechanically connecting the cable to the support element. The hot melt adhesive is applied to the support element in such a way that the hot melt adhesive fills the passage openings and lies on both sides of the support element.

Abstract: 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.

Abstract: A durable LED light engine includes an 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 open spaces in the combination of the substantially U-shaped top enclosure, the printed circuit board and the bottom enclosure are filled with a plastic sealant. Once cooled, the plastic sealant holds the combination of the substantially U-shaped top enclosure, the printed circuit board and bottom enclosure together.

Abstract: 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.

Abstract: A power system for a group of LED modules each of which includes a plurality of LEDs or series-connected LEDs, utilizes a plurality of polarized direct current power supplies with one electrical polarity separated, and the other electrical polarity commonly connected. Each individual LED, or each set of series-connected individual LEDs, in each of the LED modules, are connected in series to each of the direct power supplies and then to an opposite polarity to complete an electrical circuit.

Abstract: A bus line LED module includes a printed circuit board on which LEDs are mounted and lens portion formed over the LEDs. A pair of wires is positioned beneath the printed circuit board within a bottom portion assembly to form a top portion assembly. A pair of windows within a bottom portion assembly enables access to a portion of the wires where a metal-to-metal contact to the metal inner portion of the wires is made. A pair of metal connectors extends from the printed circuit board to make metal-to-metal contact with the metal wires. A sealing connection is made between the top portion assembly and the bottom portion assembly.

Abstract: A system and method for interconnecting LED modules that receive electrical energy from a direct current electrical energy power supply includes a first type of mating connector to provide an input of direct current electrical energy to a printed circuit board contained within an interconnectable LED module and a second type of mating connector to provide an output of direct current electrical energy to and interconnecting with another interconnectable LED module. The second type of mating connector attaches to the first type of mating connector in the next LED module in a string of interconnectable LED modules.

Abstract: 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.
