Dimming Control Including an Adjustable Output Response

摘要

The present disclosure provides improved dimming or dimmer assemblies/modules for controlling lights or loads (e.g., as part of a control or automation system). More particularly, the present disclosure provides for systems and methods for utilizing dimmer control assemblies/modules advantageously having: (i) an adjustable output response, (ii) enhanced thermal management, (iii) a voltage detector to determine amplitude and zero-crossing, and/or (iv) an estimation of power consumption for multiple loads (e.g., using a single sensor).

主权项

1. A control assembly comprising:
a first load circuit, the first load circuit including a first load control device, a second load control device, a first current detector and a first voltage detector, the first load control device in communication with a first controlled device and the second load control device in communication with a second controlled device; a processor in communication with the first and second load control devices, the first current detector and the first voltage detector; and a first line feed associated with the first load circuit and in communication with the first and second load control devices, the first current detector and the first voltage detector; wherein at least a portion of the first line feed is configured to travel to and be output by the first load control device as a first load output to the first controlled device; wherein at least a portion of the first line feed is configured to travel to and be output by the second load control device as a second load output to the second controlled device; wherein the first voltage detector includes an analog-to-digital converter, the analog-to-digital converter adapted to take a plurality of measurements of the voltage that is present at the analog-to-digital input during each cycle of the first line feed; wherein the analog-to-digital converter is adapted to communicate the measurements to the processor, the processor adapted to group the measurements into separate groups of measurements; wherein the processor is adapted to calculate the average voltage measurement of each group and determine if the average voltage measurement is positive or negative; wherein the processor is adapted to identify and analyze together consecutive groups of voltage measurements that have opposite positive/negative average voltage measurement values to estimate the voltage zero-crossing point of the first line feed's waveform.
