Abstract: The present disclosure provides a portable low voltage switching device to control the power and brightness of LEDs in LE arrays. The device is further comprised of two circuits, one power circuit to control the LED wattage, and another brightness circuit to control the LED lumens. The device is connected in between an LED driver and the LED arrays, receiving a stepped down DC voltage and splitting it across the two LED arrays. The device can provide power and adjust the brightness to both of the LED arrays, with the first LED array having a “warm” colour and the second LED array having a “cool” colour. Therefore, instead of using a single light fixture containing a single LED array, the device can be used with a single fixture having two LED arrays, providing a variety of brightness and power options to the cool and warm colours.

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.

Abstract: In one embodiment, the present disclosure is directed to an RF impedance matching network that includes an electronically variable capacitor (EVC) and a control circuit. The control circuit is coupled to a sensor configured to detecting an RF parameter. To cause an impedance match between an RF source and a plasma chamber, the control circuit determines, using a match lookup table with a value based on the detected RF parameter, a match combination of a new EVC configuration for providing a new EVC capacitance, and a new source frequency for the RF source. The control circuit then alters the EVC to the new EVC configuration, and alters the variable frequency of the RF source to the new source frequency.

The combination of master dimmer and dimming control modules provides a simple multi locations dimming control system.
