Technology

Which outcome increases when a high-brightness LED's thermal management system exhibits increased thermal resistance?

A)Reduced light output efficacy
B)Increased external quantum efficiency
C)Improved color rendering index
D)Stabilized forward current regulation

💡 Explanation

Increased thermal resistance in an high-LED's thermal interface causes a rise in junction temperature because the heat extraction rate decreases; therefore light output will decrease rather than remain stable or improve because of temperature-dependent non-radiative recombination.
