摘要

发光二极管（LED）是一种半导体固体发光器件。在可见-近红外波段的光辐射测量和光电探测器的定标中，发光二极管显示出高辐射亮度、高电光转换效率、可组合调配光谱分布、发光性能稳定等独特优点，可作为辐射度学

光度学和色度学研究的新型参考光源。本文介绍了一种光谱分布可调光源的设计，它由积分球和大量不同颜色的LED组成。在可见波段，这种光源能产生不同光谱分布，可以模拟很多不同光源的光谱分布。光源设计通过仿真使光源的光谱分布模拟目标光源的光谱分布，并设计了电源控制箱精确地控制每个LED模块。这种新型光源在光辐射测量中可以作为一种传递标准。

Abstract

Light-emitting diodes are compound semiconductor devices that convert electricity to light. In optical radiometry and calibration

LED has good performance of high luminance

energy-cost savings

long life

no pollution and small bulk. It is new reference source of radiometry

photometry and colorimetry. In this text

design of spectrally tunable LED light source has been described. It composed of an integrating sphere with a large number of LEDs. The source is designed to have a capability of producing different spectral distribution in the visible region

and it can mimic various light source. A series of simulations have been conducted to predict the performance of spectral distribution of the designed tunable source. The source has designed a power control box

it can control every LED module accurately. This new type source will be used as a transfer standard for radiometric application.
