    Abstract: The present invention provides a power adaptor for an LED lamp, 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. The power adaptor comprises a power conversion circuit and a dimmer, wherein the power conversion circuit is configured to receive and then convert an external power supply signal into a power signal; and the dimmer is configured to receive the power signal and a dimming instruction and to combine or synthesize the power signal and the dimming instruction to produce an output signal. The LED lamp receives the output signal and performs control of itself according to the manner of controlling provided by a control code in the output signal.
