Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cascading LED light strings face issues with signal attenuation, leading to incorrect determination of data signals due to long distance transmission, resulting in malfunction and abnormal behavior in lighting effects.
Innovation Solution
The implementation of a cascading LED system with a master light string and slave light strings, where each slave light string includes a signal intensifier to enhance the carry light signal, and each LED module enters a low-power-consumption mode when the voltage falls below a certain level, ensuring proper signal recognition and reduced power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple LED light strings are cascaded in series for extended lighting coverage, then the lighting area is expanded, but signal attenuation occurs during long-distance transmission causing data signal identification failure
Solution Approach 1:
The patent introduces a signal amplification circuit as an intermediary component in each LED light string. This circuit receives the attenuated data signal from the previous string, amplifies it to restore signal strength, and retransmits it to the next string. The amplification circuit acts as a mediator that compensates for signal attenuation during long-distance transmission, ensuring reliable data signal identification across cascaded LED strings.
2Speed
If a quick discharge circuit is used to quickly reduce the voltage level of the light control signal, then the signal recognition speed is improved, but the light control signal may quickly reduce to reset voltage causing unnecessary reset failure
Solution Approach 1:
The patent implements a voltage threshold detection mechanism that monitors the light control signal voltage before it reaches the reset voltage level. When the voltage approaches the critical reset threshold, the system activates a voltage clamping or buffering mechanism to prevent the signal from dropping to reset voltage. This beforehand cushioning prevents unnecessary reset failures while maintaining quick signal recognition.
3Use of energy by stationary object
If the light control signal quickly reduces below the identifiable low-level voltage, then the low-power mode activation is timely, but the signal continues to reduce to reset voltage causing abnormal determination and malfunction
Solution Approach 1:
The patent employs a feedback mechanism where the voltage level of the light control signal is continuously monitored. When the voltage drops below the low-level threshold, the system activates low-power mode for LED modules. Simultaneously, a feedback signal prevents further voltage reduction to reset voltage by adjusting the discharge rate or activating a voltage maintenance circuit. This feedback loop ensures timely low-power activation while preventing abnormal malfunctions.

AI summary
A cascading LED lights with low power consumption includes a master light string and at least one slave light string. The master light string receives a carry light signal to control LED modules. The at least one slave light string cascades the master light string. A signal intensifier of the slave light string enhances the carry light signal to drive the LED modules. When a voltage of the carry light signal is less than a low-level voltage, the LED modules enter a low-power-consumption mode.
