  • Patent number: 10153692
    Abstract: A DC current driver includes a DC current drive circuit configured to provide a DC supply current and receive a DC return current. A switch is coupled in series with the DC return current, and a supplemental power supply is coupled in parallel with the switch and configured to provide a supplemental voltage. Opening the switch diverts the DC return current through the supplemental supply and closing the switch causes the DC return current to bypass the supplemental supply.

  • Patent number: 9970646
    Abstract: A heatsink having integrated electrical and base contacts for use with a light emitting diode (LED) light source. In some embodiments, a heatsink assembly for an LED lamp includes a first metallic heatsink component having a first wall portion and a first electrical contact, and a second metallic heatsink component having a second wall portion and a second, separate contact portion. A non-electrically conducting heatsink housing is configured to house the first wall portion and the second wall portion of the first and second heatsink components such that the first electrical contact extends from the non-electrically conducting heatsink housing and the second contact portion extends from the plastic housing in a manner to facilitate connection to hot and neutral lines of a power source.

  • Patent number: 9841167
    Abstract: A lighting system and method electrically control optics of light generated by a light source. The light source generates a light defined by a light distribution. An electro-active optical component changes the light distribution responsive to a change in an electric potential applied across the electro-active optical component by an electronic control system.

  • Publication number: 20130069552
    Abstract: An organic light emitting electrical device containing an organic light emitting diode (OLED) and a power supply adapted to reduce space charge buildup in the OLED. An organic electroluminescent device has an organic light emitting diode with a first electrode and a second electrode. A power supply is electrically coupled to the first electrode and the second electrode. The power supply is configured to generate a forward bias voltage and a reverse bias voltage pulse and alternately connect the forward bias voltage to the first electrode and the second electrode, and the reverse bias voltage pulse to the second electrode and the first electrode.

  • Publication number: 20120256813
    Abstract: A lighting assembly includes a light source having a first generally planar, light source including a perimeter edge. A backsheet is disposed in substantially parallel relation with the light source, and includes at least one electrical feedthrough region extending through the backsheet and substantially covered by a contact patch disposed in substantially planar relation between the backsheet and the light source. A generally planar, connector cable extends over the backsheet and has connector pad(s) positioned thereon to associate with each feedthrough and to the light source through the contact patch. A low temperature solder material is disposed between each connector pad and contact patch for establishing electrical connection with the light source, wherein one or more of the light source, connector cable, backsheet, or any portion thereof is constructed of one or more plastics.

  • Patent number: 8258773
    Abstract: A system and method for detecting lightning strikes on a wind turbine includes detecting and measuring a parameter that is indicative of a lightning strike, which may be current induced in a conductor as a result of the lightning strike. A current receptor may be located on a component of the wind turbine and electrically coupled to a ground conductor. A current sensor is disposed on the ground conductor and generates a primary current I(p) that is proportional to a lightning strike current flowing through the ground conductor upon a lighting strike on the receptor. A signal converter sub-system is configured to convert the primary current I(p) into a processing signal. A processing sub-system is configured to receive and use the processing signal to determine an actual lightning strike on the wind turbine.
