Puas muaj cov teeb meem kev nyab xeeb hauv LED qhov chaw?
Tam sim no, lub teeb pom kev zoo thiab teeb pom kev zoo ntawm cov LEDs dawb rau cov teeb pom kev dav dav tau dhau los ntawm cov teeb pom kev zoo ib txwm muaj, thiab tuaj yeem ua tiav cov xim zoo nkauj thiab kev ruaj ntseg siab, uas tuaj yeem ua tau raws li qhov xav tau ntawm cov teeb pom kev ntse rau dimming. Tus yuam sij rau kev siv LEDs nyob ntawm seb lub teeb tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov teeb pom kev zoo thiab cov khoom siv teeb pom kev zoo.
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.
Tam sim no, pej xeem lub tswv yim muaj ntau qhov kev txhawj xeeb txog lub teeb xiav, tab sis peb tsis tuaj yeem pom qhov muag tsis pom nws.
Ntawm qhov tod tes, lub teeb xiav yog qhov tseem ceeb ntawm lub teeb dawb, uas tsis tsuas yog ua lub luag haujlwm tseem ceeb hauv kev ua kom cov xim rendering, tab sis kuj tswj lub circadian atherosclerosis. Lub hnub ci sab nraum zoov tuaj yeem txaus siab rau txoj haujlwm ntawm synchronizing cov kev cai ntawm tib neeg circadian atherosclerosis (los yog lub moos lom neeg), thiab lub teeb xiav tau txais sab hauv tsev yog tsawg dua qhov koob tshuaj tau txais los ntawm kev ua si sab nraum zoov. Lub teeb xiav thiab lub teeb txias dawb tuaj yeem siv los tsim lub teeb pom kev zoo los pab tib neeg kom tau txais cov koob tshuaj xiav xiav txhua hnub kom ntseeg tau tias lawv cov circadian rhythms nyob rau hauv kev sib raug zoo nrog lawv cov circadian rhythms.
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.
Muaj kev sib koom ua ke kev ntsuas ntsuas GB/T 20145-2006/IEC62471 rau kev phom sij xiav lub teeb nyob hauv tsev thiab txawv teb chaws. Lub teeb LED rau lub teeb pom kev zoo txhua hnub yog nyob rau hauv chav kawm 0 lossis chav kawm 1 thiab nyob rau hauv qeb kev nyab xeeb.
