Rapid developments in LEDs over the past decade have created a major growth market with completely new applications. Full color displays for large areas only became possible with the introduction of high-intensity blue LEDs, while highpower white LEDs are becoming widely used in general lighting and the automotive industry. These applications have placed increasingly stringent demands on the optical characterization of LEDs and Solid-State Lighting devices. Specific expertise is needed in order to achieve precise and reproducible results. This handbook discusses the special characteristics of LEDs and emerging OLEDs. It provides an overview of state-of-the-art measurement equipment and gives recommendations for obtaining accurate measurement results. The main goal of this handbook is to give readers new to this subject an introduction into LED metrology. However, this handbook is also a useful reference work for more experienced readers.weiterlesen
