Engineering Contradiction Analysis
1Device complexity
If the moving object detection circuit is separated from the LED lamp structure, then the LED lamp structure is simpler, but the installation becomes difficult and sensitivity decreases
Solution Approach 1:
The patent integrates the moving object detection circuit directly into the LED lamp structure, combining previously separate components (detection circuit, driving circuit, and LED lamp) into a unified integrated structure. This merging eliminates installation complexity while maintaining simplicity through functional integration at the circuit level.
Solution Approach 2:
The integrated circuit structure serves multiple functions simultaneously: it provides LED driving functionality, moving object detection capability, and lighting control in a single unified component. This multi-functionality reduces the number of separate components needed while improving installation ease and detection sensitivity.
