Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power supply solutions for LED lighting systems require multiple distinct product configurations (SKUs) to accommodate various lamp configurations, leading to inefficiencies in manufacturing and installation, as they often lack flexibility in electrical parameters and mechanical packaging, and do not easily allow for customization or remote control.
Innovation Solution
A power supply with integrated wireless communication circuitry and digital control capabilities that allows for configuration via external devices, such as smartphones, enabling customizable operation modes like constant-current or constant-voltage, dimming curves, and fault protection, which can be set during installation, distribution, or at the factory, reducing the need for multiple SKUs and allowing for remote configuration without physical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple distinct product configurations (SKUs) are provided to accommodate various lamp configurations, then the power supply can meet diverse electrical parameter requirements, but the device complexity and inventory management become more complex
Solution Approach 1:
The power supply employs dynamically reconfigurable electrical parameters through digital control circuitry. The system can switch between constant current and constant voltage modes, and adjust output parameters based on wireless configuration commands, allowing a single unit to adapt to multiple lamp configurations without requiring multiple fixed SKUs
Solution Approach 2:
The invention changes electrical parameters (output current, output voltage, dimming curves) through digital configuration received via wireless communication. This allows the same hardware platform to be reconfigured for different applications by modifying control parameters rather than changing physical components
2Adaptability or versatility
If custom configuration is performed during installation or distribution, then the number of SKUs needed is reduced, but the ease of operation requires a simple configuration interface
Solution Approach 1:
The invention replaces physical configuration interfaces (jumpers, switches, wiring) with wireless communication circuitry that accepts configuration commands via wireless protocols. This allows configuration to be performed remotely using standard handheld devices without requiring physical access to the power supply or specialized installation tools
Solution Approach 2:
The power supply includes onboard wireless communication circuitry and control logic that autonomously processes configuration commands received from external devices. The system self-configures by receiving parameters wirelessly and automatically adjusting its electrical output characteristics without requiring manual intervention or complex setup procedures
3Ease of operation
If a wireless communication interface is incorporated for remote configuration, then the ease of operation is improved, but the device complexity increases due to additional circuitry
Solution Approach 1:
The wireless communication circuitry is integrated with the existing digital control circuitry of the power supply. The same microcontroller and digital signal processing resources that manage electrical output parameters are also used to process wireless configuration commands, combining communication and control functions in a single integrated control system rather than adding separate dedicated hardware

AI summary
A power supply includes power circuitry configured to provide DC power to a separate load, and wireless communication circuitry for wirelessly communicating with an external control device such as a smart phone. A controller is configured to (1) conduct communications with the external control device via the wireless communication circuitry to receive configuration parameters, and (2) incorporate the configuration parameters into a control scheme for operation of the power supply. The power supply may be used with an LED lamp including a series of LEDs, and the configuration parameters establish desired operating characteristics including selection of constant-current or constant-voltage operation, and/or parameters for a dimming curve applied in dimming operation of the LED lamp. The power supply may be used in other applications including battery charging applications.
