近年来，发光二极管（LED）技术的快速发展使得高功率器件具有前所未有的光发射强度，可与可见激光光源相媲美。在此基础上，开发、制造和测试了两种通用装置。第一种是高功率的单led照明器，配备可交换的投影透镜，提供确定直径的均匀光斑。第二个器件是由多个大功率led组成的多led照明阵列，每个led都集成了一个单独的准直透镜。这些设备可以发射R、G、CG、B、UV或白光，并可以在脉冲或连续波（CW）模式下操作。使用外部触发信号，它们可以很容易地与相机或其他设备同步。操作方式及各项参数均可通过软件控制。各种实验表明，这些装置已经成为激光和氙灯光源的通用和有竞争力的替代品。本文介绍了该系统的原理、设计、实现性能和应用实例。
The rapid progress of light emitting diode (LED) technology has recently resulted in the availability of high power devices with unprecedented light emission intensities comparable to those of visible laser light sources. On this basis two versatile devices have been developed, constructed and tested. The first one is a high-power, single-LED illuminator equipped with exchangeable projection lenses providing a homogenous light spot of defined diameter. The second device is a multi-LED illuminator array consisting of a number of high-power LEDs, each integrated with a separate collimating lens. These devices can emit R, G, CG, B, UV or white light and can be operated in pulsed or continuous wave (CW) mode. Using an external trigger signal they can be easily synchronized with cameras or other devices. The mode of operation and all parameters can be controlled by software. Various experiments have shown that these devices have become a versatile and competitive alternative to laser and xenon lamp based light sources. The principle, design, achieved performances and application examples are given in this paper.
