The Effect of Thermal Interface Material on Led Heat Sinks
Journal Title: JOURNAL OF ADVANCED RESEARCH IN APPLIED MECHANICS & COMPUTATIONAL FLUID DYNAMICS - Year 2018, Vol 5, Issue 1
Abstract
LED’S have been used in many products due to its longevity, more power saving and higher lumens per watt. About 80% of the electrical power is wasted as heat or reductant heat which in turn increases the junction temperature of the LED’s. This increase in the temperature in the LED’S decreases the longevity and color of LED’S. Proper thermal management is required to remove this heat effectively. The heat sink design and usage of proper thermal interface materials for increasing the heat removal is required. In this paper, temperature increase in a LED fixture during a time interval with and without thermal interface material is measured and tabulated to find the effectiveness of the thermal interface material in removing more heat is studied. In addition, a simulation using Solidworks thermal simulation is done to validate the analytical thermal-time study results. The entire study we provide a guideline for the design of LED high bays in future and demonstrate the importance of the thermal interface materials in the design studied
