Patent attributes
An illuminated Christmas tree decorative light control circuit includes: a main controller and at least one branch controller. The main controller includes a main control circuit, a timing circuit, a memory circuit, a RF remote control circuit and a control output circuit capable of outputting main control signals. Each branch controller includes a signal transmission circuit capable of receiving the main control signal, a connecting terminal respectively connected to a plurality of decorative light modules (LED light string/strip equipped with a plurality of LEDs arranged linearly) installed on the Christmas tree branches, and a driving circuit arranged between the signal transmission circuit and the connecting terminal. Accordingly, the decorative light module on each tree branch can be installed independently and further connected to the corresponding branch controller, followed by connecting all of the branch controllers to a main controller. Consequently, the overall wiring is more convenient and facilitated.
