This would tend to indict an artifact in measurement rather than an indictment of the 2nd law of thermodynamics.

- edu 2y agoFrom the article, it seems that the extra energy is obtained from heat in the environment around the LED.

- Retr0id 2y agoA heat pump can operate at ">100% efficiency" without breaking the laws of thermodynamics, the trick is that its moving the thermal energy around rather than merely "producing" it. It wouldn't surprise me if the LED is doing something similar.
- toast0 2y agoIt's a well reported effect, LEDs can emit light using electrical and heat energy. That gives better than 1 efficiency of light from electric input. Not a violation of the 2nd law, just a way to beam heat out of an environment. Power levels are low though, so I haven't seen any reports of applications Oh, and this may be one of the original reports, it's dated 2012.
