Submission + - Cause of LED Efficiency Droop Finally Revealed (ucsb.edu) 1

An anonymous reader writes: Researchers from University of California, Santa Barbara in collaboration with colleagues at the École Polytechnique in France have been able to prove the theory behind LED “droop”. LED droop is when LEDs have more power pushed through them, they emit less light. With the the understanding of what Causes this, we should now start to see research go into the production of LEDs with technology to circumvent LED Droop.

Cause of LED Efficiency Droop Finally Revealed

  • Pay very close attention to LEDs. Now that we've identified the root cause of one of our biggest problems, in a few years, we'll find ways to work around those problems and extend the lifespan of an LED (and output at higher drive currents) with a minimal loss of light.

    This is EXCITING news, as the uses for this across the entire electronics industry are MASSIVE. Higher-efficiency, longer-lasting LEDs means better optical devices and such, as this same tech can be applied down into solid-state laser diodes.
