Open the camera's camera at the LED light bulb, if there is a high frequency flashing, then prove that this LED lights there is a serious problem of strobe.
Open the camera's camera at the LED light bulb, if there is a high frequency flashing, then prove that this LED lights there is a serious problem of strobe.
LED light source and light strobe
LED light source and lamp strobe mainly from the poor drive power supply, such as RC capacitive power supply, ripple high switching power supply. Test and determine the LED light source and the lamp is stroboscopic, the simple way is to open the phone camera and camera function, electronic viewfinder that lens alignment to observe the LED light source, framing screen accounted for more than 2/3 of the phone screen, Is close to the LED light source observation, such as mobile phone LCD screen to see the light source has obvious black stripes rolling or bright and dark changes, you can determine the strobe. Strobe is the frequency of flashing, is a cyclical repetitive flash, including visible strobe and unobtrusive strobe. 50 to 200Hz frequency flashing human can see the naked eye, for children and young people may be very sensitive. High-frequency flicker, due to the inertia of the human eye but can not feel, that is not aware of the strobe, therefore, can be used to do optical communication.
Storm hazard
Light and lamps give people a bright, light people live, to meet the different needs of the work. Therefore, we must give the environment of human safety.
Stroke may cause human body diseases such as epilepsy, headache, etc., can not see the unobtrusive strobe may also cause visual fatigue leading to myopia. Visible and invisible strokes will have an impact on human health, studies have shown that 100 / 120Hz strobe, may cause headaches, migraine, eye fatigue and other adverse effects, severe dimming strokes or even cause epilepsy! Especially will seriously affect the child's vision is growing.
Stimulation not only affects human health, but also affects animals and has an impact on bird reproduction (Maddocks et al., 2001), (Evans et al., 2006). Mammalians, such as cats, survive at modulated light at 100 / 120Hz, have been shown to cause the phase-locked loop of the lateral geniculate nucleus of the thalamus, and the short chains of the brain are part of the upper hills and affect the movement of the eye The main part (Eysel Burandt, 1984). Strobe will also have an impact on the shooting, poor light source, refresh the frequency is not high enough LED screen, when shooting prone to stripes, seriously affect the shooting effect.
Stroboscopic effects and associated mechanical movements in combination, will cause the mechanical movement to slow down or stop the illusion of movement. Stroboscopic effects (wheel effects, reversal effects, etc.) are identified as a class of illusions. The appearance of objects that are intermittently illuminated, rotated, or moved is altered by the fact that the strobe effect and the associated mechanical movement are combined, resulting in a significant slowdown in mechanical motion or an illusion of stopping motion, which is most likely to occur in metal machine processing, Great harm, causing the product to be scrapped or accident occurred.
