Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional linear LED drivers do not support wireless control and require AC to DC conversion, which can be resource-intensive, whereas wireless control of LED drivers can reduce resource usage, necessitating a solution for wireless control of linear LED drivers without DC conversion.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If AC to DC conversion is implemented in LED drivers to enable wireless control, then wireless control capability is improved, but resource consumption increases
Solution Approach 1:
The patent segments the LED driver system into two distinct types: wireless-controlled LED drivers with AC to DC conversion and linear LED drivers without conversion. This segmentation allows each type to operate independently with its own resource consumption characteristics, enabling wireless control where needed while maintaining energy-efficient linear operation where AC to DC conversion is not required.
Solution Approach 2:
The patent extracts the AC to DC conversion component from the LED driver system, creating a version (linear LED driver) that operates directly from AC power without conversion. This extraction eliminates the resource consumption associated with conversion while preserving the core LED driving function, and allows wireless control to be implemented selectively without mandating conversion in all systems.
2Use of energy by moving object
If linear LED drivers operate without AC to DC conversion, then resource consumption is reduced, but wireless control capability is lost
Solution Approach 1:
The patent creates a universal LED driver architecture that can function in multiple modes: linear operation for energy efficiency and wireless-controlled operation with AC to DC conversion. This multi-functionality allows the system to adapt to different requirements, providing wireless control capability when needed while maintaining the option for resource-efficient linear operation, thus resolving the contradiction between resource consumption and wireless control capability.
3Ease of operation
If wireless control is integrated into linear LED drivers, then control flexibility is improved, but device complexity increases
Solution Approach 1:
The patent merges the wireless controller integration circuit with the linear LED driver circuitry, combining control functionality and power management into a unified system. This integration allows wireless control signals to be processed and applied directly to the linear LED driver without requiring separate conversion infrastructure, thereby improving control flexibility while managing device complexity through consolidation rather than addition of separate components.

AI summary
A system integrates a wireless controller into a linear, alternating current-only driver. The system utilizes a light emitting diode driver to maintain a constant current to a light emitting diode when a current controller is operated by a pulse width modulated signal. The pulse width modulated signal to one or more light emitting diode circuits may be modified to reduce flicker, color mix, and temperature tune.
