LEDs in a State of Flux

摘要

Every week the LED's pervasiveness continues to increase. Portable electronics have become the biggest end-use market for LEDs and not only is this likely to continue but further diversify. Today, displays are a billion dollar market for LEDs but that is not to say that other portable applications are being neglected. One of the other segments with great potential is portable illumination, with many millions of flashlights sold already; the future of the good old filament light bulb seems to be doomed if recent developments are factored in.
