Description

Light-emitting diodes are being widely used due to their efficient use of power. 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, while costing the least. This book covers the design trade-offs involved in LED driving applications, from low-power to UB-LEDs and beyond.

商品描述(中文翻譯)

**描述**

發光二極體因其高效的電力使用而被廣泛應用。功率LED的應用包括交通信號燈、街燈、汽車照明、建築燈、家庭燈具替換、標誌燈(取代霓虹燈條和螢光燈管)等。驅動這些LED並不總是簡單。線性驅動效率低且產生過多熱量。使用開關電源時,主要問題是電磁干擾(EMI)和效率,當然還有成本。問題在於設計一個符合法律要求且高效的方案,同時成本最低。本書涵蓋了LED驅動應用中的設計權衡,從低功率到超高亮度(UB-LED)及更高功率的應用。
