Abstract：This paper refers to the laboratory distributed photometer measurement principle in darkroom environment, to test the light color parameters of space distribution points for the orbit directional lighting device, with the handheld spectrum color luxmeter. The LED lamps color uniformity are evaluated using this method. Less test equipments and relatively simple test methods were adopted to obtain objective and actual light color data. Quantitative analysis were made for LED lamps to meet the light color parameter evaluation requirements for the actual use cases with LED directional lighting.
