Intelligent power module for LED lamps, based on electric carrier waves with address control

Abstract

The invention discloses an intelligent power module for LED (light-emitting diode) lamps, which is based on electric carrier waves with address control. The intelligent power module comprises single-phase electric lines, and is characterized in that a plurality of LED lamps are arranged on the single-phase electric lines in series, wherein an LED lamp control system is arranged among the single-phase electric lines and each LED lamp; the LED lamp control systems comprise control modules, power modules, electric carrier wave modulation and demodulation modules, LED driving modules and dial switch address modules; the control modules are connected with the electric carrier wave modulation and demodulation modules; and the dial switch address modules are arranged on the control modules. The intelligent power module has three working modes, namely a single receiving mode, a receiving and transmitting mode and a dormant mode, and the working modes can be switched over intelligently according to a received control command, so as to reduce power consumption. The intelligent power module improves the stability and the reliability of the systems, and takes three circuit protection measures, namely output short-circuit protection, temperature protection and overcurrent protection, thereby ensuring the safety and the reliably of circuits.

Description

technical field [0001] The invention belongs to the field of control systems for LED lamps, and in particular relates to an intelligent power supply module for LED lamps based on power carrier with address control. Background technique [0002] In China, carrier aircrafts were already operating in the country in the 1940s. After decades of development, it has a considerable scale and level. However, due to the immature development of domestic chips, my country's current technology in this area is still very immature. [0003] The domestic power carrier communication market is growing slowly, but home automation has become a trend, and PLC has an undoubted broad prospect. Power carrier communication products have not been promoted on a large scale, mainly because the reliability and convenience of the products have not reached a high level, and the current relevant standards and evaluation systems are not perfect, and consumers know little about them and lack trust .
