Power Supplies for LED Driving, Second Edition

Power Supplies for LED Driving, Second Edition explores the wide use of light-emitting diodes due to their efficient use of power. The applications for power LEDs include traffic lights, street lamps, automotive lighting, architectural lights, theatre lighting, household light replacements, signage lighting (replacing neon strip lights and fluorescent tubes), LCD display backlighting, 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, efficiency, and of course cost. This book covers the design trade-offs involved in LED driving applications, from low-power, to UB-LEDs and beyond.

• Provides a practical, hands-on approach to power supply design for LED drivers
• Contains detailed examples of what works throughout the design process
• Presents commentary on how the calculated component value compares with the actual value used, including a description of why the choice was made

《LED驅動電源，第二版》探討了由於其高效能使用而廣泛使用的發光二極體。功率LED的應用包括交通燈、路燈、汽車照明、建築照明、劇院照明、家庭燈具替代品、招牌照明（取代霓虹燈和螢光燈管）、LCD顯示器背光等等。

驅動這些LED並不總是簡單的。線性驅動效率低下且產生過多熱量。使用開關電源，主要問題是電磁干擾、效率和成本。本書涵蓋了LED驅動應用中所涉及的設計取捨，從低功率到UB-LED等等。

本書提供了一種實用的、實際操作的方法來設計LED驅動器的電源。其中包含了設計過程中的詳細實例，並對計算出的元件值與實際使用的值進行了評論，包括對選擇的原因的描述。
