Garden lighting control system and method

Abstract

A garden lighting control system includes a power supply control box system for providing the power required by a plurality of connected garden lights, for changing the voltage properties of the provided power at different times, including changing the positive and negative polarity of the supply voltage, modulating the positive and negative polarity conversion frequency, and modulating the positive and negative polarity duty cycle. The garden lights identify the voltage positive and negative polarity, positive and negative polarity conversion frequency, positive and negative polarity duty cycle of the power received, and execute the pre-set lighting function of the garden lights to achieve multi-time-period zone lighting according to the function pre-selected for each garden light.

What is claimed is: 
     
         1 . A garden light control method, comprising the steps of:
 at a power supply terminal, modulating the positive and negative polarity of output power at different times, the positive and negative polarity conversion frequency, the positive and negative polarity conversion duty cycle, or both the positive and negative polarity conversion frequency and the positive and negative polarity conversion duty cycle combined state, to output control commands used to represent lighting functions;   establishing a system protocol to the relationship between the lighting function control instructions indicative of the work of the power supply voltage output from the power supply terminal from positive polarity to negative polarity, negative polarity to positive polarity, positive and negative polarity conversion times, positive and negative polarity conversion frequency, positive and negative polarity conversion duty cycle or positive and negative polarity conversion frequency and positive and negative polarity conversion work, the power supply voltage attribute condition detected by the garden light terminal and various lighting function options; and   a garden light terminal receiving the power signal from the power supply terminal, identifying the positive and negative polarity of the voltage, the number of positive and negative polarity changes, the positive and negative polarity conversion frequency, the positive and negative polarity conversion duty cycle, or the combined state and attributes of the positive and negative polarity or the duty cycle of the positive and negative polarity conversion frequency and the positive and negative polarity conversion, comparing the function setting options of the garden light side, and executing the division lighting function according to the system protocol rules, so that different garden lights are used to set and execute different zone lighting functions.   
     
     
         2 . The garden light control method as claimed in  claim 2 ,
 wherein the function setting options include lighting timing, lighting time length, light brightness, light color correspondence, and activation of external devices such as a motion detection function.
