Due to the limitation in efficacy and the lack of white light, LED was not suitable for general lighting applications in the past. With the advancement of semiconductor materials and packaging technologies, the illumination performance of LED has been greatly improved. Ten years ago high power (one watt) white LEDs were introduced with efficiencies high enough to trigger serious discussions on using LEDs for solid-state lighting (SSL) applications."-- Provided by publisher 606 $aLight emitting diodes 608 $aElectronic books. 615 0$aLight emitting diodes. 676 $a621.381522 700 $aLee$b Shi-Wei Ricky$01241980 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910555188903321 996 $aFrom LED to solid state lighting$92880844 997 $aUNINA
