← TechnologyWhat outcome happens when drive currents massively exceed forward maximums in LEDs?
A)Reduced light output at new bias
B)Accelerated efficiency degradation begins gently
C)Thermal runaway leading to destruction✓
D)Increased junction voltage is measurable
💡 Explanation
Catastrophic thermal runaway occurs from the exceeded current because the increased junction temperature causes decreased resistance and further current increases, therefore destruction is the result, rather than a slower degradation or recoverable reduced output.
