Abstract
Control over the operation of a dimmable light is supported by an interface circuit between the dimmable light and a near-field radio frequency communication controller. The interface circuit includes a first circuit that receives at least one control set point through a near-field radio frequency communication issued by the near-field radio frequency communication controller. A second circuit of the interface generates one or more electric signals in pulse width modulation based on the control set point.
Claims21
A circuit for controlling a dimmable light in response to a near-field radio frequency communication, comprising:
- a first circuit configured to receive at least one control set point through the near-field radio frequency communication;
- and
- a second circuit configured to generate at least one electric signal having a pulse width modulation (PWM) in accordance with said at least one control set point for application to said dimmable light to set a light intensity output.
