Abstract

Light-emitting diode (LED) technology has been rapidly developing due to high energy efficiency and longer lifetimes of LED luminaires. One of the main challenges in designing LED components is to manage the inter-twined relation between thermal, electrical, and optical performances. These dependencies are required to be well understood in order to operate LEDs efficiently and have accurate performance prediction at different levels of the product value chain. Delphi4LED project aims at developing standardised method to create multi-domain (thermal, electrical, and optical) compact models from the measurement data. To obtain highly reliable and representative data sets via characterisation and calibration, end-user requirements specification for diverse LED samples are needed. In this paper, we report the lists of LED parameters and components selected for measurements, simulation and calibration considering end-user needs. We also show some of the methodologies for compact thermal model development that are recommended in Delphi4LED, followed by definition of simulation benchmark problems.

Delphi4LED中多域LED紧凑型模型开发的需求规范

由于发光二极管(LED)灯具的高能效和较长的使用寿命，其技术得到了迅速的发展。设计LED元件的主要挑战之一是如何处理热学、电学和光学性能之间错综复杂的关系。为了有效地操作led，并在产品价值链的不同层次上进行准确的性能预测，需要很好地理解这些依赖关系。Delphi4LED项目旨在开发标准化方法，根据测量数据创建多领域(热、电和光学)紧凑模型。为了通过表征和校准获得高度可靠和具有代表性的数据集，需要对不同LED样品的最终用户要求规范。在本文中，我们报告了考虑到最终用户需求而选择用于测量、模拟和校准的LED参数和组件列表。我们还展示了在Delphi4LED中推荐的紧凑型热模型开发的一些方法，然后是模拟基准问题的定义。
