Abstract: A system and method for a solid state lighting network using a power system architecture, having application in a designated area to achieve energy saving control and intelligent management requirements. The present invention primarily enables implementing single or integral control of each LED light emitting device installed within a local area via a control device. The entire system is constructed using existing alternating current power lines, and the control method uses the existing power lines as channels for conveying electronic signals, and implements conversion of control signals. Moreover, alternating current carrier waves are used to complete transmission of the electronic signals, thereby achieving effective control of each LED light emitting device within a local area.

Abstract: A driver device that stabilizes current and automatically regulates voltage of a light emitting diode is capable of automatically regulating the voltage and stabilizing the current in accordance with a voltage demand, so as to provide the proper voltage and the stable current, for being applied to control color and shading of the light emitting diode. According to the actual voltage required by the light emitting diode, a current control unit controls a current-controlled transistor to output the stable current, so as to fit with the actual voltage requirement and stably control the changes of color and shading. Therefore, the requirements of energy saving, of that multiple light emitting diodes can be fitted with at a same time, and of that operating temperature can be decreased, are achieved.
