Abstract
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).
Claims4
A control assembly comprising:
- a first load circuit, the first load circuit including a first load control device, the first load control device in communication with a first controlled device;
- a processor in communication with the first load control device;
- and
- a first line feed associated with the first load circuit and in communication with the first load control device;
- 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 the processor is in communication with the first load control device via a first control signal line;
- wherein the processor is adapted to store a plurality of individual data points, each individual data point being a value that represents the magnitude of a control signal on the first control signal line that is generated for a different dim level of the first controlled device;
- wherein the individual data points are spaced apart from one another from a low dim level to a high dim level of the first controlled device;
- wherein the processor is adapted to determine a magnitude of a first control signal for a first dim level of the first controlled device that is positioned between first and second data points of the plurality of data points, the first and second data points adjacent to one another from the low dim level to the high dim level;
- wherein the processor is adapted to determine a magnitude of a second control signal for a second dim level of the first controlled device that is positioned between third and fourth data points of the plurality of data points, the third and fourth data points adjacent to one another from the low dim level to the high dim level;
- wherein the first controlled device has a non-linear relationship between power delivered to the first controlled device and the light intensity of the first controlled device when power is delivered to the first controlled device at each individual data point from the low dim level to the high dim level;
- and
- wherein the first controlled device has a linear transition in light intensity between the first dim level and the second dim level.
