Which outcome occurs for high-power LEDs operating without a heat sink?

💡 Explanation

Thermal runaway occurs because Joule heating increases junction temperature, reducing the bandgap and increasing current. Therefore, the current continues to increase leading to catastrophic failure, rather than stabilizing or undergoing radiative recombination.
