The stroboscopic and stroboscopic effects of electric light sources have brought serious harm to our work and life. However, when we applied the electric light source, we did not attract the attention and correct understanding. Scientifically correct understanding of the harmful effects of stroboscopic and stroboscopic effects of energy-saving lamps is of great practical guiding significance for the scientific application of energy-saving lamps and the construction of a bright, clear and comfortable lighting environment. Comparing the ordinary fluorescent tube under the DV with the LED fluorescent tube, you can understand the stroboscopic light more directly. You can use your camera or DV to try your energy saving lamp and computer display to see if the strobe exists, whether it is affecting you. What about vision? First, the stroboscopic and stroboscopic effects of the electric light source The stroboscopic and stroboscopic effects are two mutually causal physical quantities for the magnitude of the electric light source, the fluctuation depth of the luminous flux, and the resulting harmful effects (called stroboscopic effects). Strobe is the depth at which the luminous flux of an electric source fluctuates. The greater the fluctuation of the luminous flux, the more severe the stroboscopic. The depth of fluctuation of the luminous flux of the electric light source is directly related to the technical quality of the electric light source. The magnitude of the fluctuation of the luminous flux of an electric source is usually described by a percentage. At this stage, the widely used electric light source, such as the magnetic ballast driven T8 (26mm) straight tube fluorescent lamp, high pressure mercury lamp, high pressure sodium lamp, metal halide light flux fluctuation depth of up to 55%-65%. Some energy-saving lamps with poor technical quality on the market still have stroboscopic depths of up to 20%-30%. The stroboscopic effect refers to the harmful effect of the electric light source caused by the fluctuation of the luminous flux, that is, the harmful effect caused by the stroboscopic light. The more severe the strobe of the electric light source, the more serious the stroboscopic effect is. A tool for visually identifying and evaluating the stroboscopic and stroboscopic effects of energy-saving lamps, usually using a gyro-specific gyro. Identification and evaluation of energy-saving lamps stroboscopic and stroboscopic effects, is based on sunlight. The luminous flux of sunlight is smooth and stable, and there is no stroboscopic and stroboscopic effect. The luminous flux of the energy-saving lamp is smooth and stable, and the closer to the sunlight, the smaller the stroboscopic depth of the energy-saving lamp, and the smaller the stroboscopic effect is. Second, the performance of the stroboscopic effect of the electric light source (1) Initiating a work accident When the stroboscopic frequency of the electric light source is in integral multiple with the speed of the moving object, the moving state of the moving object will produce static, reverse, slow moving speed, and the erroneous vision of the above three states periodically repeating, causing a work-related accident. For example, the sewing machine operator in the garment industry, the needle that moves up and down at high speed, is illusory to a static state, and the finger is inadvertently injured. (2), resulting in low production efficiency The stroboscopic effect can cause visual nerve fatigue and migraine. In particular, high-pressure mercury (sodium) lamps and metal halide lamps have been widely used in the machinery industry. T8 (26mm) straight tube fluorescent lamps driven by magnetic ballasts commonly used in light industry, food, printing, electronics, textile and other industries. The stroboscopic effect is seriously jeopardized and the production efficiency is low. For example, plug-in operators on the assembly line are prone to migraine due to visual fatigue, vertigo, and difficulty in positioning. (3), hurt the eyes of teenagers After the 1980s in China, T8 (26mm) straight tube fluorescent lamps driven by magnetic ballasts are commonly used in homes, schools, libraries, etc. Due to the serious stimuli of the lighting environment, the growing primary and secondary school students suffered greatly, the visual acuity decreased significantly, and myopia increased significantly.
