ABSTRACT
Light Emitting Diodes (LED) are highly energy efficient and offer long-life times for display applications. Long life and minimal energy consumption are often the most attractive advantages for electronic devices. Because LEDs are based on compound semiconductors, which explore the direct transition between the conduction and valance band edges, thermal energy loss can be minimized during operation. However, even though these types of LEDs are based on direct transition type semiconductors, thermal energy is still emitted during operation owing to forward conduction and reverse leakage currents. This research proposes capturing this energy loss through thermoelectric module-based energy recycling methods to improve the energy efficiency of LED applications, achieving savings of up to 18%. Additional analysis was performed on high power LED sources resulting in the manufacture of a high-power LED light grid system.
