The LED stroboscopic effect actually have two concepts: One is strobe which mean the depth of light flux fluctuations, the more violent fluctuation, the depth of strobe more lager. Second is stroboscopic effect which mean the human visual produce negative effects of electric light flicker, the more violent fluctuation, the negative effects more lager, the damage will be more bad. The flicker and s...
Under the effect of high temperatures, the structural characteristics of non-metallic materials, insulation materials will change greatly, which manifests itself softened or melted. Ball pressure test is used to test the heat resistance of non-metallic materials and insulating materials. It indicates the requirements of the ball pressure test in IEC60695, UL, IEC884-1, GB / T5169.21-2006, GB4706.1...
