Which limit occurs when an LED's junction temperature increases excessively?

💡 Explanation

Thermal runaway occurs because increased temperature raises intrinsic carrier concentration which increases current. This positive feedback further heats the junction temperature and reduces efficiency, therefore, damaging the LED, rather than quantum tunneling or avalanche effects under voltage limits.
