LED Heatsink Optimization using Self Powered Active Cooling
Journal Title: Journal of Advance Research in Instrumentation and Control Engineering - Year 2018, Vol 5, Issue 1
Abstract
Light Emitting Diodes (LED)s have been rapidly replacing conventional light sources in residential and commercial segments. LEDs have low lighting to electrical energy efficiency. Most of the electrical energy consumed by the LEDs gets dissipated in the form of heat. For high power LEDs, this necessitates a large heatsink and fixture. Active cooling using fans is one method of reducing fixture size and weight. A Thermo Electric Generator (TEG) based active cooling method can lead to a significant size and weight reduction of the heatsink. In this paper, a new approach based on the iterative thermal simulations is presented to design a TEG based heatsink. Mathematical modeling of this system is presented to enable design parameter calculations. Iterative thermal steady state and flow simulations are carried out to arrive at an optimized heatsink design. This methods leads to an optimized heatsink design. All the results of this work are presented
