  • Patent number: 10045421
    Abstract: The disclosure is directed at a system, power supplied to a solid state lighting (SSL) device when an operational fault condition is sensed such as when the power level being supplied to the device is sensed to be meeting or higher than an expected or predetermined level. The system, method and apparatus provide a recovery aspect which means that the SSL device will not be automatically shut down (or power being supplied to the SSL device will not be immediately stopped) upon the discovery of the operational fault condition but will enter a recovery mode.

  • Patent number: 9942954
    Abstract: The disclosure is directed at a method and apparatus for controlling solid state lighting. The solid state lighting is controlled by the combination of a constant current reduction approach and a dithering approaching. The constant current reduction approach is used over a high light intensity range while the dithering approach is used over a low light intensity range.

  • Patent number: 9591713
    Abstract: The disclosure is directed at a system, method and apparatus for monitoring and limiting power supplied to a solid state lighting (SSL) device when an operational fault condition is sensed such as when the power level being supplied to the device is sensed to be meeting or higher than an expected or predetermined level. The system, method and apparatus provide a recovery aspect which means that the SSL device will not be automatically shut down (or power being supplied to the SSL device will not be immediately stopped) upon the discovery of the operational fault condition but will enter a recovery mode. The system may be used for white light general illumination applications as well as to color changing applications.

  • Patent number: 9041379
    Abstract: A bootstrap assist circuit and a startup circuit comprising a voltage controlled switch and a startup ramp voltage generator connected to the voltage controlled switch that will control a high side switch, a dimming interface or an enable/disable input function. Said system is used to provide a bootstrap technique to continuously switch a floating high side switch (MOSFET) by continuously charging a capacitor and then “level shifting” said capacitor voltage across the gate and source of the said high side switch to turn the switch on.
