Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED decorative lights with flashing bubbles lack controller-adjustable flashing functions and programmable patterns, necessitating complex structures due to physical separation of constant-illumination and controllable branches.
Innovation Solution
Interspersing controllable flashing bubbles among constant-on LEDs, where the bubbles receive control signals at the controller's power terminals, allowing the controller to adjust flashing functions and patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If constant-illumination and controllable LED branches are physically separated and twisted together, then each branch can be controlled independently, but the light string structure becomes complex
Solution Approach 1:
The patent merges constant-illumination LEDs and controllable flashing bubbles into a single integrated light string structure. Both types of LEDs are connected in parallel to the same power supply lines, eliminating the need for separate twisted branches. This integration maintains independent control capability while significantly simplifying the overall structure.
Solution Approach 2:
The patent creates a universal light string structure that can accommodate both constant-illumination LEDs and controllable flashing bubbles within the same system. The controller is designed to handle multiple types of LED components through a unified interface, allowing the same physical structure to serve multiple lighting functions simultaneously.
2Device complexity
If flashing bubbles are controlled by driver chips with fixed patterns, then the control circuit is simple, but the controller cannot adjust flashing frequencies or blinking modes
Solution Approach 1:
The patent implements dynamic control of flashing patterns through a controller that can adjust flashing frequencies and blinking modes in real-time. The controller receives external control signals that dynamically modify the operating parameters of the flashing bubbles, allowing transitions between different flashing patterns and frequencies without requiring physical circuit changes.
Solution Approach 2:
The patent changes the control parameters from fixed driver chip configurations to adjustable controller outputs. The controller can vary timing parameters, duty cycles, and flash patterns based on external signals, enabling the same hardware to produce multiple different flashing effects by simply changing electrical parameters rather than physical circuitry.
3Device complexity
If a single control chip controls the entire circuit, then the control structure is simple, but programmable flashing patterns cannot be achieved
Solution Approach 1:
The patent introduces an intermediary controller that sits between the power supply and the LED components. This controller acts as a mediator that receives external control signals and translates them into appropriate drive signals for the LEDs, enabling programmable flashing patterns without requiring the power supply itself to be complex or programmable.

AI summary
The present invention discloses an LED decorative light with controllable flashing bubbles, comprising: a controller and a light string. The positive terminal and negative terminal of the controller are connected to the light string, where the controller supplies power to the light string through the positive and negative terminals while loading a control signal on either/both the positive terminal and negative terminal. The light string includes a plurality of LEDs and a plurality of controllable flashing bubbles, with the controllable flashing bubbles receiving the control signal to achieve an adjustable flashing effect. By interspersing controllable flashing bubbles among constant-on LEDs and enabling them to receive control signals loaded by the controller at power output terminals, the invention realizes an LED decorative light whose flashing functions or patterns can be controller-adjusted.
