Light Head Configuration for Independent Power Supply Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft remote power supplies for light source emitters often require simultaneous replacement with the light source emitter assembly due to changes in brightness levels, number of emitters, or drive voltage, leading to inefficiencies and unnecessary replacements.
Innovation Solution
A light system comprising a light head with memory and communication components and a remote power supply with a controller and power converter, allowing the light head to communicate configuration information via a data bus to adjust the power supply output independently, enabling replacement of light heads with different design parameters without affecting the remote power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the light head is replaced with updated light source emitters having different design parameters, then the light output characteristics improve, but the remote power supply must also be replaced simultaneously
Solution Approach 1:
The power supply controller dynamically adjusts its operation based on configuration information received from the light head via communication interface. The controller modifies drive current, voltage, and operational parameters in real-time to match the specific light source emitter characteristics, enabling compatibility across different light head designs without hardware replacement
Solution Approach 2:
The system changes operational parameters (drive current, voltage, flash patterns) based on the light head configuration information. The controller reads configuration data from the light head memory and adjusts power delivery parameters accordingly, allowing the same power supply to support multiple light head variants with different emitter specifications
2Productivity
If the remote power supply is designed to support multiple light head configurations, then replacement independence is achieved, but the control system complexity increases
Solution Approach 1:
The light head provides its own configuration information through an integrated memory device and communication interface. The power supply controller automatically reads this information and configures itself without external intervention, eliminating the need for manual setup or complex programming when light heads are replaced
Solution Approach 2:
The system implements a feedback loop where the power supply controller continuously receives configuration information from the light head and adjusts its output accordingly. This closed-loop control ensures optimal performance while adapting to different light source characteristics without requiring complex pre-programming

AI summary
Systems and methods for allowing replacement of updated light heads with different design parameters to become independent of the remote power supply. An exemplary light system includes a light head remote from a power supply component. The light head includes one or more light-emitting diodes (LEDs) or other light emitting devices, a memory that stores configuration information and a communication component. The power supply component includes a power converter, a memory, and a controller. The power converter outputs an electrical signal for driving the one or more LEDs. The memory stores light head configuration information. The controller receives configuration information from the communication component via the data bus, generates and sends instructions, based on at least one of the configuration information stored in the power supply component memory or the configuration information received from the light head, to the power converter.
