← TechnologyWhich consequence results when elevated temperatures cause LED driver capacitor degradation?
A)Increased LED current oscillations
B)Decreased LED luminous efficacy
C)Higher harmonic distortion appears✓
D)Reduced overall driver efficiency
💡 Explanation
Increased temperatures cause the capacitor's equivalent series resistance (ESR) to increase by *dielectric relaxation*, leading to greater harmonic distortion because filtering is less effective. Therefore, higher harmonic distortion results, rather than stable current or reduced LED output.
