Abstract

This paper presents harmonics and thermal characteristic of Light Emitting Diode (LEDs) Lamps which are used in residential and commercial applications as energy efficient lighting bulbs. It is done by performing experimental tests on various LED lamps available in the market. The current drawn by several LED lamps are first measured to investigate the electrical characteristics. These measurements provide current harmonic characteristic of individual lamps. Then various configurations of LEDs were connected to a laboratory scale feeder to analyze the diversity factors. Furthermore, heat generation levels of the tested LED lamps are investigated to measure the thermal characteristics of LED lamps. The results show that individual LED bulbs produce considerable amount of harmonics but it could be reduced by combining various types of LED bulbs. Furthermore, the diversity factor could be improved if LED lamps are mixture with Compact Fluorescent Lamps (CFLs). Results also shows that the thermal characteristic of LED lamps is much better compare to the performance of CFLs.
