LED LAMP SINGLE LIVE WIRE INTELLIGENT CONTROL APPARATUS

SHENZHEN POWER2CONTROL SM...

1. A light-emitting diode (LED) lamp single live wire intelligent control apparatus, comprising:at least one first LED lamp half-wave driving device,
a single live wire control circuit connected in series on a same alternating current (AC) loop; and
at least one group of control output circuit;
wherein the first LED lamp half-wave driving device comprises a first direct current (DC) driver and a first rectifier diode connected in parallel with the first DC driver of first LED lamp;
wherein the single live wire control circuit comprises a half-wave DC power supply circuit and a first central processing unit (CPU) control circuit; the half-wave DC power supply circuit comprises a first DC power circuit and a second rectifier diode connected in parallel with the first DC power circuit; a conduction direction of the second rectifier diode in an AC loop is opposite to the conduction direction of the first rectifier diode of the first LED lamp half-wave driving device in the same AC loop;
wherein the control output circuit comprises at least one first switch element and a third rectifier diode connected in parallel with the first switch element.
