With the popularization of household chemical light therapy beauty equipment represented by the large row lamp, more and more consumers choose and use this kind of beauty instrument, but the reporter also found that many large row lights on the market have quality problems, endangering the eyes and body of consumers. Including substandard blue light harms the retina, the most serious of which is the strobe hazard.
According to the Chinese national standard GB/T 31831-2015 and IEEE 1789-2015 standard, the strobe of LED lamps is safe when the waveform frequency is above 3125Hz. It means that as long as the waveform frequency exceeds 3125Hz, then the LED products are strobe 0 hazard and safe, below the waveform frequency of 3125Hz and the fluctuation depth limit exceeds the standard, the strobe is unqualified, and there may be serious strobe hazards.
How big is the harm of unqualified strobes, the reporter also visited relevant experts, and after verifying some information, it was found that the harm of strobe is amazing, including Shanghai First People's Hospital, Sichuan Provincial People's Hospital, Chinese People's Liberation Army General Hospital and other experts pointed out:
1. The strobe hazard will irritate the eyes and optic nerves, which will lead to a series of problems such as conjunctival hyperemia, dry eyes, visual fatigue, vision loss, etc., and even damage the retina and cornea, resulting in blindness;
2. Stroboscopic hazards can also cause systemic diseases such as migraine and photosensitive epilepsy;
3. Stroboscopic hazards target specific groups of people and special occasions, and can also cause distraction and autism.
With such a serious hazard, consumers do not have professional equipment, how can they know that the products they buy do not have strobe hazards? As early as 2019, the CCTV 315 party broke out the strobe hazard of LED lights, and also introduced a simple detection method, consumers can use the mobile phone's built-in photo function, facing the LED light, if the mobile phone screen flashes seriously, the product has a strobe hazard!
The reporter bought the two most popular sales of the large row of lights, and after testing them one by one with a mobile phone, it was found that a single-screen large row of lights had serious strobe hazards, but another "extremely cute folding screen large row of lights" products did not have any strobe hazards, and then the reporter consulted the customer service, and the customer service also provided a test report of strobe 0 hazards issued by Weikai Testing Technology Co., Ltd.
Through inquiry, the reporter found that the strobe standard of Jimeng 20000Hz is 7 times that of the national standard safety standard 3125Hz, and the safety far exceeds the national standard, at the same time, the customer service also introduced to the reporter that the Jimeng folding screen lamp is the pioneer of the folding screen in the large row lamp industry, and won the first place in the category on the line in April.
1. The product has 0 hazards, whether it is a report of 0 hazards of strobe or a report of 0 hazards of blue light, Jimeng has been obtained as an industry benchmark early, allowing consumers to use a large row of lights with 0 hazards;
2. 2 times the product efficacy, the effect of the large row of lights is determined by the luminous area and the number of lamp beads, the 1000 square centimeters of the large row of lights of the extremely cute folding screen is 2 times that of similar products in the market, and the 464 lamp beads are far beyond similar products, bringing better product effects;
3. No dead angle to illuminate the whole face, Jimeng, as the pioneer of the folding screen large row lamp, has solved the problem that the large row lamp industry has been unable to solve, the flat single-screen large row of lights, illuminating the face with arc, can only shine on the nose, the cheeks can not shine, and finally the nose is white, the cheeks are black, so that consumers become yin and yang faces, but the dual-screen design of the folding screen shines on the whole face without dead ends, and the whole face is white;
4. The product bracket comes with the Jimeng folding screen large row lamp product, which is different from other large row lamp external brackets, which is troublesome and has a long illumination distance and poor effect.
Finally, the reporter also reminded consumers that when buying LED products, through two tips, you can love beauty while avoiding the harm of strobes.
Before purchasing: take the initiative to ask the merchant to show a strobe 0 hazard detection report;
After purchase: Use the mobile phone to take photos mode, aim at the LED lights, the screen does not flicker seriously, then the strobe is 0 harm.
