While operating near maximum current, which outcome occurs when localized imperfections within an LED's semiconductor crystal lattice impair heat dissipation?

💡 Explanation

When imperfections impede heat flow, resistive heating accelerates a positive feedback loop aka thermal runaway, because increased temperature further elevates resistance; therefore light output diminishes due to non-radiative recombination mechanisms, rather than improved efficiency from carrier behaviour.
