Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drivers for solid state light sources require manual or digital configuration of jumpers to adjust output currents, leading to increased costs and complexity.
Innovation Solution
A driver port with a series of shunt resistors and multiple connection points allows for selectable output currents, eliminating the need for manual or digital configuration by varying the shunt resistance to provide different currents for loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual or digital configuration of jumpers is used to adjust output currents, then different current values can be achieved for different applications, but device complexity and cost increase
Solution Approach 1:
The driver output is segmented into multiple connection points (first, second, third connection points) corresponding to different current output levels. Each connection point is associated with specific shunt resistors, allowing the system to provide different current values by simply changing the connection point without requiring complex configuration mechanisms.
Solution Approach 2:
The driver is designed with multi-functionality to provide multiple current output levels (first, second, and third current values) through a single unified structure. The shunt resistors and connection points work together as an integrated system that can adapt to different current requirements without needing separate configuration components or mechanisms.
