Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional decorative lighting systems require multiple power transformers and control units, leading to timing deviations and irregular lighting effects due to differences in chip pulse periods, necessitating a solution for synchronous luminescence across multiple light units.
Innovation Solution
An RGB decorative lighting system with a power cable connected to luminous devices in parallel, featuring a power conversion unit with a step-down and rectifier circuit, and a control unit with a light control module and signal synchronization module that counts AC cycles for synchronized control of light units, eliminating the need for transformers and synchronization controllers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional decorative lighting uses separate control units for each light unit, then each light unit can be controlled independently, but timing deviations occur due to differences in chip pulse periods causing irregular lighting effects
Solution Approach 1:
The patent combines the control unit and power transformer into a single integrated module that is common to all light units. This merged design eliminates timing deviations between separate control units while maintaining independent control capability through individual control signals transmitted via the power cable.
Solution Approach 2:
The power cable serves multiple functions: it provides power transmission to light units and simultaneously transmits control signals from the integrated control unit. This multi-functional design eliminates the need for separate control wiring while ensuring synchronized timing across all light units.
2Use of energy by moving object
If different power transformers are designed and matched for lighting with different numbers of light units, then power supply can be optimized for each configuration, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The integrated control unit and power transformer module is designed to be universal and adaptable to different numbers of light units. The module can be configured for various lighting scenarios without requiring different transformer designs, reducing manufacturing complexity while maintaining power optimization capabilities.
Solution Approach 2:
The system allows parameter adjustments (such as resistance values in the power transformer circuit) to be changed based on the number of light units connected, rather than designing different transformers for each configuration. This enables a single universal design to adapt to various power requirements.
