The applications for power LEDs include traffic lights, street lamps, automotive lighting, architectural lights, household light replacements, signage lighting (replacing neon strip lights and fluorescent tubes), and many more. Powering (driving) these LED's is not always simple. Linear driving is inefficient and generates far too much heat. With a switching supply, the main issues are EMI and efficiency, and of course cost. The problem is to get a design that meets legal requirements and is efficient, 517 3 $aPower supplies for light emitting diode driving 606 $aLight emitting diodes$xPower supply 606 $aElectric power supplies to apparatus 615 0$aLight emitting diodes$xPower supply. 615 0$aElectric power supplies to apparatus. 676 $a621.3815/22 22 676 $a621.381522 676 $a621.381522 700 $aWinder$b Steve$0878245 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9911006623903321 996 $aPower supplies for led driving$92031036 997 $aUNINA
