This work quantitatively surveys the power electronics components within grid-tied LED luminaires, with detailed experimental characterization to help benchmark the most current state-of-the-art industry LED drivers available to the consumer market. Twenty drivers are surveyed from a variety of consumer A-type LED luminaires. Relevant performance metrics, such as efficiency and power density, are defined and analyzed to generalize potential design trade-offs in an LED driver. In addition, driver design considerations of two prominent LED emitter technologies, matrix and filament type, are compared quantitatively. An associated experimental test-bed also describes the method for minimally-disruptive extraction and comprehensive measurement of an industry LED driver.
