Introduction

This standard provides for the implementation of reproducible LED lamps, LED lamps and LED modules (collectively referred to as LED devices) for luminosity and color measurement. The request was made and suggestions were made for the data report. Reliable and accurate acquisition of photometric data of LED devices is a basic requirement for lighting system design and product performance evaluation. Passed in Measuring these parameters under standardized conditions can ensure the consistency of data between laboratories (within the declared measurement uncertainty limit), and Makes the performance comparison between different products possible. This standard covers the relevant LED performance standards issued by national standards, and compliance with the luminosity and chromaticity requirements of LED devices The measurement method of the test. The shape, geometry and color of LED devices are rich and varied. For each LED device, its luminosity and chromaticity performance must be considered. LED lights, LED lamps and LED modules testing method
