Abstract

Rapid growth of Solid-State Lighting market has been supported by progress in Light Emitting Diode (LED) technology. Strong competition requires that lighting product development cycle should be shorter and more effective. Optimal design of a LED luminaire in major degree depends on thermal-electro-optical properties of LEDs in use. These properties are required to be accurately characterized and well predicted for various operating conditions of the LEDs within luminaire in close interaction with other parts of the system. Delphi4LED project [1] aims at developing standardised method to create multi-domain (thermal, electrical, and optical) compact models from the measurement data. Boundary-independent, accurate and well junction temperature-controlled iso-thermal electro-optical characterization procedure for LED samples is required to obtain highly reliable and representative data sets as an input for the compact model. Often, thermal and optical characterization experiments are performed separately at dedicated equipment. In this paper, we report the results of our evaluation and experimental verification of various sources for uncertainties and inaccuracies originated from separation of thermal and optical measurement procedures.

led等温电光热测量程序的评估

发光二极管(LED)技术的进步支持了固态照明市场的快速增长。激烈的竞争要求照明产品的开发周期应更短、更有效。LED灯具的优化设计在很大程度上取决于所使用的LED的热电光特性。这些特性需要准确地描述和很好地预测灯具内led与系统其他部分密切相互作用的各种操作条件。Delphi4LED项目[1]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。为了获得高度可靠和具有代表性的数据集作为紧凑模型的输入，需要对LED样品进行边界独立、精确和良好结温控制的等温电光表征过程。通常，热学和光学特性实验在专用设备上分别进行。在本文中，我们报告了我们对热测量和光学测量程序分离引起的各种不确定度和不准确性的评估和实验验证的结果。
