  • Patent number: 10923306
    Abstract: An indirectly heated cathode ion source having an electrically isolated extraction plate is disclosed. By isolating the extraction plate, a different voltage can be applied to the extraction plate than to the body of the arc chamber. By applying a more positive voltage to the extraction plate, more efficient ion source operation with higher plasma density can be achieved. In this mode the plasma potential is increased, and the electrostatic sheath reduces losses of electrons to the chamber walls. By applying a more negative voltage, an ion rich sheath adjacent to the extraction aperture can be created. In this mode, conditioning and cleaning of the extraction plate is achieved via ion bombardment. Further, in certain embodiments, the voltage applied to the extraction plate can be pulsed to allow ion extraction and cleaning to occur simultaneously.

  • Patent number: 10880968
    Abstract: Methods and systems for improved control of dimmable, white color tunable, multiple channel LED based illumination systems are described herein. The methods and systems described herein improve the utilization of LEDs comprising a multiple channel white light LED based illumination system, along with improved control of brightness and color of emitted light. In one aspect, a multiple channel electrical power driver includes an independent current controlled Direct Current/Direct Current (DC/DC) electrical power converter electrically coupled to each LED string having a different color output. The use of independent DC/DC power converters enables current to be supplied to each LED channel simultaneously up to the rated maximum continuous operating current level in each channel. Thus, the sum of the current provided to each LED channel exceeds the rated maximum continuous operating current of each of the LED channels.

  • Patent number: 10827575
    Abstract: A load control device (e.g., an LED driver) for controlling the intensity of a lighting load (e.g., an LED light source) may provide a wide output range and flicker-free adjustment of the intensity of the lighting load. The load control device may comprise a load regulation circuit, a control circuit, and a filter circuit (e.g., a boxcar filter circuit) that operates in a different manner in dependence upon a target current. When the intensity of the lighting load is near a low-end intensity, the control circuit may adjust an operating frequency of the load regulation circuit in response to the target current, and may control the filter circuit to filter a current feedback signal during a filter window that repeats on periodic basis. When the intensity of the lighting load is near a high-end intensity, the control circuit may control the filter circuit to constantly filter the current feedback signal.
