Abstract
An LED control system is provided for connection to an LED lighting system via a power line to control the LED lighting system using commands formed by manipulation of frequency and amplitude of a signal transmitted over the power line. The signal may be for example a wave or a sequence of pulses. The signal may be provided in superposition with line power or the line power may be formed as the signal.
Claims16
A command system for controlling a light emitting diode (LED) lighting system, the command system comprising:
- a command generator configured to connect to a power line and to form commands by manipulating multiple characteristics of power transmitted over the power line to the LED lighting system, the multiple characteristics including a frequency of the power and a voltage amplitude of the power, each of the commands being formed of changes in one or a combination of the multiple characteristics;
- and
- a functional distribution system configured to connect to the power line to receive the transmitted power and configured to receive one or more of the commands by analyzing one or more of the multiple characteristics of the transmitted power, and to control one or more LED drivers of the LED lighting system in response to the one or more commands.
A method of controlling an LED lighting system comprising:
- at a command generator connected to a power line, forming commands by manipulating multiple characteristics of power transmitted over the power line to the LED lighting system, the multiple characteristics including a frequency of the power and a voltage amplitude of the power, each of the commands being formed of changes in one or a combination of the multiple characteristics, and
- at a functional distribution system connected to the power line and to one or more LED drivers of the LED lighting system, receiving the transmitted power and receiving one or more of the commands by analyzing one or more of the multiple characteristics of the transmitted power, and controlling the one or more LED drivers of the LED lighting system in response to the one or more commands.
