Abstract: A switch mode power supply controller provides power to a pair of light sources. The controller includes a low voltage programmable current source and adjusting elements for independently adjusting the current to the LED light sources. The controller also includes a first communication port for receiving a communication from an external device, such as a dimmer, or from another power supply controller; and a second communication port for sending a communication to a third power supply controller. These ports provide an upstream and downstream communication capability through a chain of controllers so that input from a device can be communicated upstream and downstream.

Abstract: A high efficiency LED billboard lighting system with four LED modules replacing existing lighting modules. Each module has six heat sink assemblies arranged in two rows. The heat sink assemblies comprise an LED package mounted on a heat sink reflector. The LED package has a flat fine diffusing lens positioned over the diode. A diffusing lens is spaced apart from the heat sink assemblies. An LED controller is provided for each module, with power factor corrected, switch mode Power Supply, where the secondary side can be connected directly to a battery to monitor and charge one or more battery, and can run directly from the battery.

Abstract: A bypass circuit is provided for each LED in a series to permit continued operation with reduced lighting in the event of an LED failure. The bypass circuit is provided in parallel to the LED and comprises a Zener Diode provided in parallel to a thyristor. Upon LED failure, the voltage across the Zener Diode is increased thereby triggering the thyristor which is maintained in a triggered mode as long as current flows through the series circuit.

Abstract: An LED assembly comprising an LED light source positioned between a heat sink and a heat conductive glass element, and at least one hold-down element, such that the hold-down element provides a compressive force to hold the heat conductive glass element against the LED light source, thereby pressing the LED light source against the heat sink. In one example, a ? inch glass element with a surface area of five times the LED diffuser surface area is held over the LED light source by one or more sections of spring wire inserted through holes in the heat sink.

Abstract: A method of producing high capacity capacitors with a very large number of layers. Alternating layers of conductive and insulating materials are deposited by ion deposition without breaking a vacuum or inert gas chamber. For planar substrates, layer deposition may proceed simultaneously on both sides of the substrate and on multiple substrates. Continuous deposition may be used for round substrates. Inner layers of a device may have a microscopic thickness in a range of about 80 to 140 Angstroms for aluminum oxide and about 40 to 70 Angstroms for aluminum to create an atomic proximity effect to improve capacitance. Defects may be accommodated by self-healing and by creation of isolation islands.

Abstract: A two part device and method for converting a single wavelength light source such as blue LEDs to white light. A separable diffuser light converter is provided in proximity to a directional light source such as plurality of blue LEDs provided on a printed circuit board substrate. In a planar example, red and green phosphors are provided in a polymer, silicon rubber, or epoxy carrier which is applied to the inner surface of a glass or acrylic diffuser. The diffuser is a transparent or translucent material such as glass, acrylic, polycarbonate, or ceramic. The diffuser is removably supported in proximity to the light source. The diffuser light converter may be selected for its phosphor properties, and may be replaced as the diffuser material or phosphor layer degrades.
