  • Patent number: 7242150
    Abstract: A two-wire dimmer for control of a lighting load from an alternating-current (AC) power source includes a semiconductor switch, a power supply, and a control circuit. The power supply includes an energy storage input capacitor that is able to charge only when the semiconductor switch is non-conductive. The control circuit continuously monitors the voltage on the input capacitor and automatically decreases the maximum allowable conduction time of the semiconductor switch when the voltage falls to a level that will not guarantee proper operation of the power supply. The dimmer of the present invention is able to provide the maximum possible conduction time of the semiconductor switch at high end (i.e., maximum light intensity) while simultaneously ensuring sufficient charging time for proper operation of the power supply, and hence, the dimmer.

  • Publication number: 20070085755
    Abstract: A compact antenna for use in a device for controlling the power delivered to an electric load and operable to transmit or receive radio frequency signals at a specified frequency is presented. The antenna comprises a first loop of conductive material having a capacitance and an inductance forming a circuit being resonant at the specified frequency, and a second loop of conductive material having two ends adapted to be electrically coupled to an electronic circuit. The second loop is substantially only magnetically coupled to the first loop and is electrically isolated from the first loop. In a first embodiment of the antenna, the first and second loops are formed on respective first and second printed circuit boards, which allow for a small, low-cost antenna that is easy to manufacture and maximizes efficiency. When the antenna is installed in a load control device, such as a dimmer, the first loop of the antenna is mounted on an outer surface of the device.

  • Patent number: 7190124
    Abstract: A dimmer circuit provides AC power to an inductive lighting load in series with the dimmer circuit. A bidirectional semiconductor switch has a control electrode with a control signal for determining the power provided to the load. The switch in normal operation is controlled to block voltage in first and second half-cycles of the AC voltage. In a failure mode it can block the AC voltage in only one half-cycle. A controller for the switch determines the failure mode of the switch occurs which can cause an asymmetry between the half-cycles and thus a DC voltage component. A power supply supplies power to the controller from across the dimmer circuit. The controller drives the switch into substantially full conduction during most of the half-cycle which the switch is able to control; and drive the switch into non-conduction for a period of time during that same half-cycle so as to reduce the DC voltage component to prevent excessive transformer heating.
