Abstract

The introduction of LEDs has made slow progress entering general illumination. Describing LED technology adoption as slow highlights that almost 50 years has elapsed from the first LED to products with today´s high brightness white light LEDs. The human story of LED technology development is itself amazing (as told in Dupuis and Krames), and the results of these struggles are about make LED technology truly ubiquitous. The introduction of LEDs into automotive headlamps is now underway. The introduction of the LED headlamp will improve overall automotive energy efficiency. This survey paper drives to thermal aspects of this headlamp transition.
