Abstract: 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.
