为了解决传统配光曲线只能反映LED发光二维特性、立体感太差及不便于人为观察比较的难题，提出一种新的基于高级图像编程语言(LabVIEW)的LED三维特性(光强空间分布)快速检测方法。在传统光强空间分布检测方法的基础上，采用多路光度探测单元同步测试，可在0.2s内一次性由31个探测单元同步测得LED光源的二维光强空间分布（配光曲线）。通过增加旋转机构转动待测LED样品，依次测得i(i=180/)条配光曲线。最后由自研软件将i条配光曲线进行数据汇总处理，便可得到LED光源的光强空间分布的三维立体图。该检测方法具有速度快、精度高、信息量大等优点，并且具有实时性和直观性。

A new testing method for LEDs spatial intensity distribution based on the high-level image programme language (LabVIEW) was introduced to overcome the shortcomings of the conventional method, whose light distribution curve can only reflect the two-dimensional light-emitting characteristics of LED and the third dimension is difficult to be observed and compared by human eyes. It incorporated synchronized multipath photometric detection in the traditional method, with 31 detection units to measure two-dimensional spatial intensity distribution (lighting distribution curve) of the LED source synchronously within 0.2s. By rotating LED test sample, i(i=180/) items of the lighting distribution curve were measured one by one. All the lighting distribution curves were collected and processed by the custom software, and three-dimensional solid map of the LEDs spatial intensity distribution was obtained. The method has the real time and high throughput features, and it is fast, accurate and straightforward.
