INTENSITY CONTROL AND COLOR MIXING OF LIGHT EMITTING DEVICES
First Claim
1. A method for modulating intensity of light emitted by a light emitting device using a digital pattern of a signal, the method comprising steps of:
- receiving, by a controller, a setting for an intensity of light for a remote lighting device;
receiving, by the controller, an instruction to control the remote lighting device;
generating, by the controller for the remote lighting device, a signal having an instruction, a time period and a duty cycle corresponding to the setting for the intensity of light, the time period comprising a first time interval and a second time interval, a first portion of the signal within the first time interval comprising a first digital pattern corresponding to at least a portion of the instruction, a duty cycle of the first portion of the signal different than a duty cycle of the second portion of the signal, the first digital pattern comprising at least two bits;
determining, by the remote lighting device, the duty cycle of the time period of the signal received from the controller, the duty cycle based on a sum of durations of time for which the signal within the first time interval and the second time interval comprises a high value; and
establishing, by the remote lighting device, intensity of the light emitted based on the duty cycle while taking an action based on at least the portion of the instruction identified by the first digital pattern.

Abstract
The present disclosure presents systems and methods for controlling light intensity and color mixing of light emitted by lighting devices. A controller may use a setting for an intensity of light and an instruction to generate, for a remote lighting device, a signal comprising the instruction and a duty cycle within a time period of the signal that corresponds to the setting for the intensity of light. The signal may comprise a digital pattern corresponding to at least a portion of the instruction. The remote lighting device may determine the duty cycle of the time period of the received signal based on a sum of durations of time for which the signal within the period comprises a high value. The remote lighting device may establish intensity of the light emitted based on the duty cycle while implementing an action based on the identified instruction.
