Abstract

T his article presents the background on the development of solid-state lighting technology, which is gaining popularity as a light source application. This review focuses on the main characteristics of solid-state lighting devices as well as their supply requirements and the effect of temperature on light-emitting diode (LED) performance. LED drivers are designed to achieve the best operation conditions without degrading the longer lifetime that this technology achieves in comparison to other popular light sources. Offline LED drivers include active power factor correction while current control with low ripple is required to supply the LED units or string arrangements. Methods to achieve balanced current sharing on paralleled LED strings and some of the latest contributions on LED drivers are also explained.
