Abstract
The present invention provides an LED lamp, a control method and a control apparatus thereof, and an LED lamp system, each of which may achieve the function of light dimming in a current LED lamp without having to modify its original structure(s) wherein the current LED lamp originally could not have the function, or may achieve better dimming control of parallel-connected LED lamps. A method of controlling an LED lamp includes combining or synthesizing a power signal and a dimming instruction to produce an output signal, wherein the power signal comprises a constant DC, and the dimming instruction includes a control code comprising a specific sequence of high/low voltage levels for providing a manner of controlling the LED lamp. The LED lamp receives the output signal and performs control of itself according to the manner of controlling provided by the control code.
