LED yorug'lik manbalarida xavfsizlik xavfi bormi?
Hozirgi vaqtda umumiy yoritish uchun oq LEDlarning yorug'lik samaradorligi va chiroq samaradorligi an'anaviy yorug'lik manbalaridan oshib ketdi va karartma uchun aqlli yoritish ehtiyojlarini qondirishi mumkin bo'lgan yuqori rang berish va yuqori barqarorlikka erishish mumkin. LEDlarni ishlatishning kaliti lampalarning yorug'lik ko'rsatkichlari va tegishli yoritish moslamalari talablariga javob berishiga bog'liq.
Regarding the photobiological safety of LED, you can refer to the white paper "General Lighting LED and Blue Light" jointly released by the International Semiconductor Lighting Alliance, the National Semiconductor Lighting Engineering RD and Industry Alliance and the China Lighting Society in July 2013. The white paper clearly mentions that the correct use of qualified white LED products for general lighting is completely safe for human eyes.
Hozirgi vaqtda jamoatchilik fikrida ko'k chiroq haqida ko'p tashvishlar mavjud, ammo biz buni ko'r-ko'rona inkor eta olmaymiz.
Bir tomondan, ko'k yorug'lik oq yorug'likning muhim tarkibiy qismi bo'lib, u nafaqat rang berishni ta'minlashda muhim rol o'ynaydi, balki sirkadiyalik ritmni ham tartibga soladi. Tashqi quyosh nuri insonning sirkadiyalik ritmini (yoki biologik soatini) tartibga solishni sinxronlashtirish funktsiyasini qondirishi mumkin va bino ichida olingan ko'k yorug'lik ta'siri ochiq havoda qabul qilingan dozadan ancha past. Moviy yorug'lik va salqin oq yorug'lik manbalari odamlarning sirkadiyalik ritmlari tabiiy sirkadiyalik ritmlari bilan uyg'un bo'lishini ta'minlash uchun zarur bo'lgan kunlik ko'k yorug'lik dozasini olishga yordam berish uchun mos yorug'lik muhitini yaratish uchun ishlatilishi mumkin.
On the other hand, the "blue light hazard" we usually hear refers to the fact that if the radiant brightness of the 400-500nm blue light band of the light source is too high, the eyes may cause photochemical damage to the retina after looking directly at the light source for a long time. The blue light problem is essentially the combined effect of radiance, blue light weighting function and time. From a spectral point of view, the proportion of blue light in the LED spectrum increases when the color temperature increases, but there is nothing special compared with the blue light in the fluorescent lamp spectrum. At the same time, the blue light safe brightness limit of LED is similar to that of fluorescent lamp.
Uyda va xorijda ko'k rangli retina xavfi uchun GB/T 20145-2006/IEC62471 yagona reyting spetsifikatsiyasi mavjud. Kundalik umumiy yoritish uchun LED lampalar 0 yoki 1-sinfga tegishli va xavfsizlik toifasiga kiradi.
