  • Patent number: 10448471
    Abstract: Certain aspects involve lighting systems in which a dimming curve of the illumination can be selectively modified. For instance, a lighting system includes a light source configured for emitting light at a target color temperature and a switch configured to receive a selection of a dimming curve from a predefined set of dimming curves. When in a first position, the switch configures the light source to adjust a lumen intensity of the light source according to a dimming adjustment signal and a first dimming curve. When in a second position, the switch configures the light source to adjust the lumen intensity according to a dimming adjustment signal and a second dimming curve that is different from the first dimming curve.

  • Patent number: 10446372
    Abstract: An ion source having dual indirectly heated cathodes is disclosed. Each of the cathodes may be independently biased relative to its respective filament so as to vary the profile of the beam current that is extracted from the ion source. In certain embodiments, the ion source is used in conjunction with an ion implanter. The ion implanter comprises a beam profiler to measure the current of the ribbon ion beam as a function of beam position. A controller uses this information to independently control the bias voltages of the two indirectly heated cathodes so as to vary the uniformity of the ribbon ion beam. In certain embodiments, the current passing through each filament may also be independently controlled by the controller.

  • Patent number: 10375778
    Abstract: A single-segment linear constant-power LED driving circuit and method. The circuit comprises: a voltage input module, an LED load, a power switch tube, a sampling resistor, an over-voltage control module for detecting the voltage at a drain terminal of the power switch tube, a current control module for limiting a peak current of the LED load, and a comparison module. When an input voltage is greater than a turn-on voltage of the LED load, the current control module limits the peak current so that the current average value in different input voltage periods is constant. When the input voltage is greater than a set value, current flowing through the LED load is turned off, thereby reducing power consumption. When the input voltage is less than the turn-on voltage of the LED load, the LED load is turned off.

  • Patent number: 10362652
    Abstract: A lighting device, and method of controlling a power stage thereof, is provided to stabilize operation at low output currents. An output current is sensed as a feedback signal and provided to control circuitry, which further defines upper and lower boundaries for a control band about an average sensed input control value. A reference signal corresponds to the average sensed input control value, wherein adjustments to the reference signal are enabled only when an actual sensed input control value extends beyond the control band. The upper and lower boundaries may be linearly or non-linearly approaching the average control value as a function of increases in the average control value, to prevent control adjustments in particular for low output current conditions. Control signals are generated for driving one or more switching elements in the power stage, based at least in part on the feedback signal and the generated reference signal.
