Abstract
A light string controlling circuit for single node and a method thereof are provided. The light string controlling circuit for single node includes a plurality of light-emitting elements, a power source element, a master controller and a plurality of single-node controllers. The master controller outputs a power supplying request to the power source element to instruct the power source element to supply power to the plurality of light-emitting elements sequentially. The plurality of single-node controllers are connected to the plurality of light-emitting assemblies respectively, and each of the single-node controllers outputs an emission control signal to control the luminous state of the corresponding light-emitting assemblies.

A light string controlling circuit for single node, comprising:
- a plurality of light-emitting assemblies connected to each other;
- a power source element connected to the plurality of light-emitting assemblies, the power source element is configured to supply power sequentially to the plurality of light-emitting assemblies;
- a master controller connected to the power source element, the master controller is configured to output a power supplying request to the power source element to instruct the power source element to supply the power;
- and
- a plurality of single-node controllers connected to the plurality of single-node controllers respectively, each of the plurality of single-node controllers is configured to output an emission control signal for controlling each of the corresponding light-emitting assemblies.
A light string controlling method for single node, comprising the following steps:
- outputting a power supplying request from a master controller to a power source element;
- supplying power from the power source element sequentially to a plurality of light-emitting assemblies according to the power supplying request;
- and
- outputting a plurality of emission control signals respectively by a plurality of single-node controllers to control luminous states of the plurality of light-emitting assemblies.
