1. White LED technologies
LEDs (Light Emitting Diodes), all made of semiconductors (a polarized semiconductor junction through which a current flows), emit light that can be considered monochromatic (spectral width at half-height between 15 and 30 nm). However, there are different types of semiconductor, doped in different ways, which allow us to scan a large part of the visible spectrum (from near-UV, at 380 nm, to near-infrared, at 750 nm).
To produce a white light emission, the two manufacturing methods the most common (90-95% of the LED market) are called...

Statistical and economic data
At the end of 2008, LED lighting accounted for less than 2% of the total market.
The next 4 to 5 years will see a sharp increase in their market share in a number of areas (figure 1...
