摘　　要：能够获得高质量、高对比度图像的光源,对于片式电子元件的图像分析至关重要。论述的LED组合光源充分考虑了工业实际照明中的影响因素,针对片式电子元件的不同结构,利用ZE-MAX光学设计软件建立模型和光学照度分析,并进行了实际照明实验和图像二值化分析论证。实验证明,该光源适用于绝大部分片式电子元件的照明,并取得良好的图像效果。A light source that can help to get a high quality and great contrast image, is seriously important for analysis of sheety electronic components images. The design of the LED takes full consideration of influencing elements in industrial illuminance. According to different structures of sheety electronic components, we build a model and analyse the luminance by virtue of ZEMAX. The experiments of illuminance and analysis of binary images, demonstrate that this light source is suitable for the most of sheety electronic components and has gained better image effect.
