Power Supplies for LED Driving
ID: 174372
Steve Winder
Light-emitting diodes are being widely used for their efficient use of power. The applications for power LEDs include traffic lights, street lamps, automotive lighting, architectural lights, household light replacements, signage lighting, and neon 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 the most of it, while costing the least. This book covers the design of trade-offs in LED driving applications, from low-power to UB-LEDs and beyond.
* Practical, "hands-on" approach to power supply design for LED drivers;
* Detailed examples of what the design process;
* Commentary on how to calculate the value of the product.
Introduction; Characteristics of LEDs; Driving LEDs; Linear Power supplies; Switching Power Supplies; Selecting electronic components for power supplies; Magnetic; EMI and EMC Issues; Thermal issues; Safety issues.
