Claim 5:
6. The power line carrying signal pixel control light emitting diode system of claim 5, further comprising:
a first capacitor electrically connected to the micro-controller working voltage source, the detecting capacitor, the micro-controller and the first switch;
a rectifying diode electrically connected to the detecting resistor and the light emitting diode lamps;
a clamping zener diode electrically connected to the micro-controller working voltage source, the detecting capacitor, the micro-controller, the first switch and the first capacitor;
a second capacitor electrically connected to the detecting capacitor, the micro-controller, the first switch, the first capacitor, the rectifying diode and the clamping zener diode; and
a voltage-dividing resistor electrically connected to the micro-controller working voltage source, the first capacitor, the rectifying diode, the clamping zener diode and the second capacitor,
wherein the clamping zener diode is used to clamp the alternating-current power to supply a power to the micro-controller.
