Don't underestimate the harm caused by stroboscopic lighting. Stroboscopic is closely related to neurological diseases such as migraine, headache, autism, visual fatigue and discomfort. It can seriously cause illusion to the human eye and cause accidents.
At the 3.15 party in 2017, a test broadcast by CCTV made the people of the whole country know the word "LED strobe". The frequency of using LED lighting products in modern homes is getting higher and higher. From the living room, bedroom, bathroom to study room, there are always different types of LED lamps. Manufacturers are also happy to label LED products with "no stroboscopic", "natural light", and "eye protection", but the quality of these products is uneven and the prices are far from each other.
Another year is "3.15", then has your LED light changed to "no strobe"? Tencent Home Reporter asked the Bulls to see the LED related technical personnel for verification. This technical flow article allows you to read the LED strobe and learn to purchase anti-strobe LED luminaires.
First of all, come to a concept of science: what is called "strobe"?From a professional point of view, "strobe" refers to the fluctuation of the electric light source's electric flux at a certain frequency, and the exact name of "no stroboscopic" is "undetectable stroboscopic". The human eye can generally perceive light flashes below 80 Hz, at which time the human eye can perceive changes in light and dark. In the CCTV broadcast test, the phone was pointed at the screen and found to have a streak distribution, which was caused by the strobe.

The stroboscopic hazard is huge, so don’t underestimateDon't underestimate the harm caused by stroboscopic lighting. Stroboscopic is closely related to neurological diseases such as migraine, headache, autism, visual fatigue and discomfort. It can seriously cause illusion to the human eye and cause accidents.
Studies have shown that 3-70Hz low-frequency scintillation light source may cause photosensitive epilepsy; 100Hz scintillation light source is identified as causing headache, migraine; for 120Hz frequency scintillation light source may affect people's emotions, boredom, anxiety and so on. The visual illusion caused by the stroboscopic effect and the associated mechanical motion is very dangerous in industrial settings.
As for photosensitive epilepsy, there is another extremely horrific case: at the end of 1997, more than 700 children in Japan were sent to hospital for seizures at the same time. The cause of this collective illness turned out to be a strong flashing picture of the cartoons broadcast on TV. .
The danger caused by stroboscopic is huge, especially when the elderly and children in the family are under the stroboscopic LED lighting for a long time, which is more likely to cause discomfort. Therefore, understanding the stability of the light source in the home and preventing stroboscopic conditions is directly related to the health of the family. If you use inferior LED lighting products at home, it will greatly increase your health risks.
