Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for synchronizing LED light strings either require simultaneous powering on with the same AC power supply or suffer from increasing clock frequency errors over time due to the use of crystal oscillators.
Innovation Solution
A method and system utilizing a high-precision clock signal, such as a satellite clock signal, to synchronize LED light strings by generating a standard clock, dividing it into time periods, and converting the data into control signals using a data conversion module, allowing for synchronized display without the need for simultaneous power on and minimizing clock errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If crystal oscillator is used as clock source, then device complexity is reduced, but measurement precision deteriorates over time
Solution Approach 1:
The patent introduces an external high-precision clock signal as an intermediary source, receiving timing information from satellite navigation systems (GPS, Beidou, GLONASS) to synchronize LED light string displays. This external clock signal acts as a mediator that provides stable, high-precision timing without requiring complex internal clock generation circuits, thereby improving measurement precision while keeping device complexity low.
2Reliability
If simultaneous powering on with same AC power supply is used, then synchronization is achieved, but ease of operation deteriorates
Solution Approach 1:
The patent uses satellite navigation system clock signals as an intermediary synchronization source. Instead of requiring all LED light strings to be powered on simultaneously from the same AC power supply, the system receives timing information from satellites (GPS, Beidou, GLONASS) and uses this external reference to achieve synchronization. This eliminates the need for coordinated power-on operations while maintaining reliable synchronization.
Solution Approach 2:
The patent replaces the mechanical/electrical synchronization method (simultaneous power-on via AC power supply) with a signal-based synchronization method using satellite navigation timing information. This substitution allows LED light strings to be powered on independently while still achieving precise synchronization through the shared satellite clock reference signal.
3Ease of operation
If remote controller with crystal oscillator is used, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The patent maintains the ease of operation advantage of remote controllers while replacing the crystal oscillator clock source with an external high-precision satellite-based clock signal. The remote controller continues to provide convenient remote operation, but now synchronizes with the precise timing information from satellite navigation systems, thereby improving measurement precision without sacrificing operational ease.

AI summary
A method and system for realizing synchronous display of LED light strings based on a high-precision clock signal, which relates to the field of LED technology and specifically comprises the steps of: performing synchronization timing for a data processing module based on a high-precision clock signal to generate a standard clock; dividing the standard clock into several time periods, each time period circularly corresponding to a group of program data; and converting the program data into a suitable control signal by means of a data conversion module and outputting it to the LED light strings. The present invention enables LED light strings of different controllers to change synchronously, and the distances between the controllers are not limited, and the synchronization effect can be achieved whenever the power is turned on.
