Abstract

The present invention discloses a controlling device for LED decorative lights, a LED decorative light and a controlling method for LED decorative lights. A controlling device for LED decorative lights includes a power inverting module, a multi-mode controlling signal emitting module being coupled with the said power inverting module. The said multi-mode controlling signal emitting module further includes a monitoring component, a signal distributing device coupled with the monitoring component and a signal socket connected with an external LED light. The said signal distributing device is able to output two PWM (Pulse Width Modulation) driving signals to the said signal socket. The present invention only requires two signal cables and two driving signals to achieve the display control for lights, and therefore is economical.
