Light pulsation is not only visually unpleasant, but can also lead to various unpleasant consequences for the human body. Due to pulsation, people suffering from nervous diseases may experience headaches, fatigue and even seizures. With pulsating light, it is more difficult to concentrate on work, eye strain and general fatigue may occur. Pulsation is most dangerous for children. To measure the level of light pulsation, special devices are used – heart rate monitors, but its presence can be determined using any thin and long object (for example, a pencil) very simply. . visible pulsation of light. In the worst case, when the ripple factor is 100%, the light turns completely on and off 100 times per second. Sometimes the light does not go out completely, then the pulsation coefficient is lower. All people have different susceptibility to pulsation, and even one hundred percent pulsation is not noticed by everyone immediately, but if you quickly move your gaze from one object to another. pulsation begins to be noticeable. Ripple occurs because the network uses alternating current: one hundred times per second, the voltage changes from zero to maximum, and then to zero. When incandescent lamps were used for lighting, their spirals, having great inertia, “smoothed out” the ripples of the mains voltage and their ripples were almost invisible. LEDs have no inertia and unless additional measures are taken, all LED lamps or luminaires powered from the network will completely turn off and turn on 100 times per second. In good lamps and lighting devices, ripple is completely suppressed using capacitors, but, unfortunately, sometimes manufacturers save the light source and begin to quickly move it in a semicircle. If there is no visible pulsation, the pencil outline will close. to be “smeared”. If there is a pulsation of light, you will see “a lot of pencils” like in this photo. The sharper the contours of these pencils, the stronger the pulsation. © Alexey Nadezhin/ammo1.livejournal.com I am convinced that there should be no light with visible pulsation in residential premises. If you find a light source that is pulsating, it should be replaced. The same goes for monitors. In order for the pulse to be measured and “seen”, I developed a simple device – the “People’s Pulse Monitor”. Of the more or less accessible devices, Opple Light Master Pro and Opple Light Master 4 can measure everyone’s pulse! © Alexey Nadezhin Source
