Engineering Contradiction Analysis
1Reliability
If resistors are used to mix light emissions of two LEDs with different CCTs, then the mixed CCT can be achieved, but the voltage becomes unstable and the luminous efficacy becomes unstable
Solution Approach 1:
The patent changes the circuit parameter from using resistors to using diodes for current control. Diodes provide more stable voltage regulation and current control compared to resistors, thereby stabilizing the mixed CCT and luminous efficacy while reducing circuit complexity.
Solution Approach 2:
The patent replaces the manual mechanical switching system with an automated diode-based circuit system. This substitution eliminates the need for manual toggling and provides more stable electrical characteristics, resolving the contradiction between reliability and device complexity.
