Abstract
Disclosed is an individually accessible LED light system in which color and luminosity of the LED lights are individually controlled. Each of the LED lights can comprise an LED light bank, which can contain any number of lights. The primary colors can be used in the LED bank to create any desired color. The LED light bank can also be incorporated on a single chip with an address and control circuit.
Claims14
A system for controlling illumination and color of individual LED lights of a plurality of individually accessible LED lights comprising:
- a power supply that is connected to said plurality of individually accessible LED lights, said power supply generating a power signal that is amplitude modulated with a signal address that is an address encoded in said power signal of at least one of said individual LED lights of said plurality of individually accessible LED lights, and illumination data for said at least one of said individual LED lights of said plurality of individually accessible LED lights, to create an encoded amplitude modulated power signal;
- an address circuit that generates a chip address for said individual LED lights;
- a control circuit in said individual LED lights that compares said chip address with said signal address, downloads said illumination data whenever there is a favorable comparison of said chip address and said signal address and generates pulse width modulation signals in accordance with said illumination data to control illumination of said individual LED lights;
- an LED light bank having at least one LED that receives said pulse width modulation signal and is illuminated in accordance with the duty cycle of said pulse width modulation signal.
A method of controlling illumination and color of individual LED lights of a plurality of individually accessible LED lights that are connected to a power source comprising:
- amplitude modulating a power signal, from said power source, that powers said plurality of individually accessible LED lights, with a signal address and illumination data, to generate an encoded amplitude modulated power signal which individually addresses and controls said individual LED lights;
- transmitting said encoded amplitude modulated power signal to said individual LED lights;
- providing chip addresses that comprise a specified address for said individual LED lights;
- comparing said signal address of said encoded amplitude modulated power signal with said chip addresses of said individual LED lights;
- downloading said illumination data in said individual LED lights whenever there is a favorable comparison between said signal address and said chip address;
- illuminating said individual LED lights in accordance with said illumination data.
