综合介绍或申报理由：

光学设计对最终LED产品的质量和照明效果起着决定性作用，而精密的光学设计有赖于于详尽准确的光度学数据。然而在一些LED产品或照明设计中，基于传统分布光度测量的数据并不能达到预期的效果，特别是在光源与光学元件或被照面较近时。此种情况下，基于空间亮度分布测量的近场分布光度学能够提供完整的光线模型，具有明显的优势。

GO-NR1000近场分布光度计具有全自动的计算机控制系统，适用于LED封装等小型光源的近场光度测量。GO-NR1000使用成像亮度计在不同角度方向采集光源的亮度分布，能够获得完整精确的光源特性数据，更高效、准确地实现发光体的光学设计和设计评估，同时通过相应算法建立光源完整准确的光线模型，配合Tracepro等光学软件能对照明产品进行精确的二次光学设计和研发。此外，在GO-NR1000上配备高精度照度计和光谱仪，可实现待测光源照度的实时监测，并可对光源的颜色性能进行准确的分析和评估。

Optical design play a decisive role in the quality and lighting effects of the final LED products, and precise optical design depends on the detailed and accurate optical data. However, in some LED products or lighting designs, adopting the traditional far-field data can’t achieve the desired results, especially when the light sources are close to optical elements or illuminant surface. In this case, the near-field distribution measurement based on the spatial luminance distribution can provide complete rays model with obvious advantages.

与国内外同类产品或同类技术的比较情况：

GO-NR1000基于国内外相关的最新标准文件要求，配置高性能的成像亮度计，采用精密的测控技术，并结合功能强大的分析软件，实现光源的近场光度学的准确测量分析，无论在硬件配置还是软件功能上都属于国内外领先水平。

硬件上，在光源夹具上配有制冷装置，并采用具有TE制冷功能的百万像素级的成像亮度计，探测器的光谱响应函数严格与CIE视觉响应函数相匹配，且具有较大的亮度测量线性动态范围，保证了图像亮度测量的准确性，另外，结合高精度的测角仪和精密的测控技术，使成像亮度计绕被测光源旋转，测量并记录待测光源在各个方向的分布，即得到光源上各发光点在各个方向上的光通量，根据光学原理推导出光线模型，利用光线模型就可进一步推导出空间任意平面或曲面的照度分布、远场光强分布等参数。

软件上，GO-NR1000配备功能强大的专用分析软件，保证了大数据量的数据传输和复杂计算的分析能力，完全满足国内外相关标准文件对测量角度间隔等的要求建议。

Based on the latest domestic and international standards, GO-NR1000 is equipped with a high-performance imaging luminance meter, precise measurement technology and powerful analysis software to achieve accurate measurement and analysis of near-field photometry of light sources, which is a leading level at home and abroad in terms of hardware configuration and software functions

In terms of hardware, the light source fixture is equipped with a refrigeration device, and a megapixel imaging luminance meter with TE refrigeration are adopted. The spectral response function of the detector is matched with the CIE V(λ) function and has a large linear dynamic range, which ensures the accuracy measurement of image luminance. With the combination of high-precision goniometer and precise measurement and control technology, the imaging luminance meter is rotated around the light source to be measured to collect the luminance distribution of the tested light source, then the luminous flux of each emitting element of the light source in all directions is deduced, so as to establish a detailed ray model to derive the illuminance distribution and far field light intensity distribution on arbitrary surface.

On the software, GO-NR1000 equipped with powerful software guarantees the transmission of large amounts of data and the analysis of complex calculations, which fully meets the requirements of relevant standards for the measurement of angular intervals.
