  • Controlling current flowing through LEDs in a LED light fixture
    Patent number: 9185758
    Abstract: An alternating current (“AC”)-powered light emitting diode (“LED”) driver is described herein for driving one or more arrays of series-connected LEDs. The LED driver includes a first transistor that includes a collector-emitter path connected in series with at least one LED of an array of series-connected LEDs. The LED driver also includes a second transistor configured to selectively activate the first transistor based on a level of current through the array of series-connected LEDs. The array of series-connected LEDs has a turn-on voltage.
    Type: Grant

  • Dimmable driver circuits for light emitting diodes
    Patent number: 8779691
    Abstract: A circuit for dimming a light emitting diode is provided. The circuit includes an alternating current input voltage that is delivered to a light emitting diode. The circuit also includes a correction circuit configured to monitor the input voltage, which also delivers a current to the light emitting diode, wherein the current delivered to the light emitting diode is commensurate with the input voltage. The circuit also includes a simulation circuit electrically coupled to the correction circuit and configured to deliver an additional voltage to the correction circuit to modify a setpoint voltage when the input voltage falls below a predetermined value.

  • Method and system for improving start-up time of a light emitting diode (LED) driver at reduced input voltage
    Patent number: 8629631
    Abstract: Improving start-up time of a light emitting diode (led) driver at lower input voltage is accomplished with a quick start circuit comprising a constant current source that replaces the traditional trickle charge start-up path for charging of a Vcc capacitor supplying operating voltage to an SMPS controller. Also the constant current source will only be operational during SMPS start-up, then will turn off after the SMPS is capable of producing its own regulated power supply to the Vcc terminal of the SMPS controller, thereby minimizing E2/R power losses in the SMPS.
