Solution Overview
Problem
Current exterior lighting solutions, such as those using fluorescent tubes or mercury metal, are inefficient and have short lifespans, and existing LED-based solutions lack independent control over multiple LEDs, requiring all LEDs to be adjusted simultaneously.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple LEDs are used to provide required lumens, then illumination intensity is improved, but device complexity increases and independent control is lost
Solution Approach 1:
The patent divides the LED array into multiple independently controllable groups or zones. Each group can be controlled separately through individual control circuits, allowing selective activation of specific LED groups based on detection signals from sensors. This segmentation enables independent control while maintaining the overall illumination function, resolving the contradiction between providing sufficient lumens and maintaining device complexity at manageable levels.
2Ease of operation
If all LEDs are adjusted simultaneously, then control simplicity is improved, but adaptability to different scenarios deteriorates
Solution Approach 1:
The patent implements dynamic control where LED groups can be selectively activated or deactivated based on real-time detection signals from external sensors. The system transitions from static all-or-nothing control to dynamic selective control, where different combinations of LED groups are activated depending on the detected object type (person, vehicle, animal). This dynamic approach maintains ease of operation through automated sensor-based control while significantly improving adaptability to different scenarios.
Solution Approach 2:
Different LED groups are assigned to illuminate different zones or areas, with each group having its own control circuit. When a sensor detects an object in a specific zone, only the corresponding LED group is activated. This local quality approach allows the system to provide targeted illumination where needed while keeping other areas dark, improving both adaptability and energy efficiency without complicating the overall control mechanism.
3Adaptability or versatility
If external sensors and independent control circuits are added for each LED group, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent employs universal control circuits that can manage multiple LED groups through standardized interfaces and protocols. The control system is designed to handle detection signals from various sensor types and translate them into appropriate LED group activation patterns. This multi-functionality approach allows the system to achieve high adaptability through standardized, reusable control modules rather than requiring unique complex circuitry for each LED group, thus managing device complexity while maintaining versatility.
