LED lighting system
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.
1. A combination of an LED lighting system and a command generator for controlling the LED lighting system,
the command generator being configured to manipulate multiple characteristics of power transmitted to the LED lighting system, the multiple characteristics including a frequency of the power and a voltage amplitude of the power, to form commands, each command formed of changes in one or a combination of the multiple characteristics; and
the LED lighting system comprising:
a support structure;
at least one LED array in the support structure;
at least one electrical connector for connection to a line carrying the transmitted power to provide the transmitted power as input power to the LED lighting system;
power control circuitry for the at least one LED array, the power control circuitry in electrical communication with the electrical connector; and
at least one power analyzing and processing circuitry in electrical communication with the electrical connector, and being configured to:
identify one or more of the multiple characteristics of the input power,
compare the one or more of the characteristics of the input power to preset control criteria either in hardware or software or both to yield a comparison result, and
control the power control circuitry providing same or different power control for a corresponding set of LEDs in the at least one LED array according to the comparison result.
2. The combination of claim 1 , wherein the transmitted power comprises a wave, the frequency being a wave frequency.
3. The combination of claim 2 , wherein the wave is an AC power wave.
4. The combination of claim 2 , wherein the wave is a carrier wave superimposed with the power transmitted to the LED lighting system.
5. The combination of claim 1 , wherein the transmitted power comprises DC pulses, the frequency being a pulse frequency.
6. The combination of claim 1 , wherein the command generator is configured to form multiple commands simultaneously.
7. The combination of claim 1 , wherein the command generator is configured to receive wired or wireless signals from one or more external interface modules and generate commands corresponding to the wired or wireless signals.
8. The combination of claim 1 , wherein the at least one power analyzing and processing circuitry is configured to control the power control circuitry in response to the one or more commands to cause the power control circuitry to cause LEDs of the corresponding set of LEDs to produce one or more of dimming, brightness changes, color changes, flashing or color temperature variations.
