Energy efficiency of a LED lighting system using a Peltier module thermal converter

Blog Article

With LED lighting systems, 70% of the energy consumed is lost in thermal form.It would be possible to increase the efficiency of the system by converting this wasted thermal energy into light.Some proposals using Peltier modules Photo Printed Wooden Plaque have been made.This article is interested in the limits of these solutions by evaluating the drop in the luminous efficiency of the LED system induced by the thermal effects generated by the addition Gelatin of the Peltier module compared to the potential gain in terms of electrical power produced.
