Carbon arc lamp aging test

Carbon arc lamp aging tester of carbon arc lamp is mainly divided into two kinds: one kind is enclosed carbon arc lamp, carbon arc lamp is a kind of sun. Both carbon arc lamp is applied to the early equipment, which had used for textile light test, which is originally used for light fastness test of coating. Enclosed carbon arc lamp light is a set of carbon rod, current arc through the carbon rods. But carbon arc spectral power distribution (SPD) and natural daylight SPD is large, neither in the natural sunlight shortwave ultraviolet radiation, no daylight between 400-800 nm of high strength and energy. Sunlight type carbon arc lamp matching of the SPD and the sunlight of the SPD has improved, but both between 50 to 350 nm spectral distribution or have bigger difference. So, overall, detection and ? of carbon arc lamp
