Kwixesha elidlulileyo, bekungekho ndlela yokulinganisa eneenkcukacha kunye novavanyo lokwenzakala okubangelwa kukukhanya kwemitha kumzimba womntu.Indlela yokuvavanya yendabuko kukuvavanya umxholo we-ultraviolet okanye ukukhanya okungabonakaliyo okuqulethwe kumaza okukhanya.Ke ngoko, xa kuvela itekhnoloji entsha yokukhanyisa i-LED, sinokusebenzisa umgangatho ofanayo we-IEC / EN 60825 njengovavanyo lweemveliso zelaser.I-IEC / EN 60825 ikakhulu ivavanya kwaye ibala amandla okukhanya kobude obunye.Ngoku i-LED iyibhanti ebanzi yokukhanya, ngoko i-Standard IEC / EN 60825 ayisasebenzi ekukhanyeni.Ke ngoko, i-IEC yenze i-IEC / EN 62471 yokukala umngcipheko.
Injongo ye-IEC / EN62471 kukuvavanya iingozi zokukhanya kwemitha ehambelana nezibane ezahlukeneyo kunye neenkqubo zesibane, zithathela indawo ngokupheleleyo iimfuno kumgangatho wamandla weemveliso ze-LED kumgangatho we-IEC / EN60825, ukongeza iimfuno ze-photobiological, kubandakanya ubunzulu bemitha, ukukhanya kwemitha, njl. ., kwaye uhlele iimveliso ngokwedatha yovavanyo, kubandakanya:
Akukho ngozi;Udidi Ⅰ ingozi (umngcipheko ophantsi);Udidi Ⅱ ingozi (umngcipheko ophakathi);Udidi Ⅲingozi (umngcipheko ophezulu)
Inqanaba lokukhululwa (akukho mngcipheko): ayiyi kubangela nayiphi na ingozi ye-photobiological radiation phantsi kweemeko ezilinganiselwe ezichazwe kulo mgangatho.
Iklasi I (umngcipheko ophantsi): phantsi kweemeko eziqhelekileyo zokusetyenziswa, ayiyi kubangela ingozi ye-photobiological radiation ngokokuziphatha kwabantu okuqhelekileyo kokukhanya.
Udidi II (umngcipheko ophakathi): ngokokuphepha okumangalisayo kwamehlo omntu ukuya kwimithombo yokukhanya okukhanyayo okanye impendulo engathandekiyo yemitha ye-thermal, ayiyi kubangela ingozi ye-photobiological radiation.
Udidi III (umngcipheko ophezulu): kwanokukhanya okukhawulezileyo kuya kubangela ingozi yemitha.
Umgangatho we-EU EN62471:2008 uphunyezwe ukususela ngoSeptemba 1, 2009, kwaye inxalenye ye-LED ye-EN60825 ayiyi kusebenza ngokupheleleyo ngoSeptemba 1, i-2010.
I-EN 62471 igutyungelwe ngumyalelo we-CE Low Voltage Directive (LVD Directive 2006 / 95 / EC) kunye ne-artificial light radiation Directive (AORD 2006 / 25).
I-IEC / EN 62471 isebenza kuzo zonke izibane kunye neenkqubo zesibane, kubandakanywa ii-LED, ii-incandescent bulbs, izibane ze-fluorescent, izibane zokukhupha igesi, izibane ze-arc kunye nezinye izibane kunye nezibane.
Ummiselo we-EU 244 / 2009 kwiimfuno zokwanelisa umbane kwizibane zasekhaya ezingalathisiyo ukwachaza ukuba uvavanyo kwimitha ye-UV kufuneka lwenziwe ngokuhambelana ne-IEC / EN 62471 (ingakumbi kwizibane zokonga umbane).
Ukuqinisekiswa kwe-CB yezibane ze-LED ezizilungisayo kufuneka zibandakanye ukuvavanywa kokhuseleko lwe-photobiological ngokuhambelana ne-IEC 62471 kunye ne-IEC TR 62471-2.Ngokwesisombululo se-OSM / CTL, izibane ze-LED kufuneka zivavanywe ngokwe-IEC / EN 62471. Ileyibhile yemodyuli ye-LED yokukhusela iliso lomntu iya kubhekisela kwi-IEC / EN62471

Oku kulandelayo luluhlu lomda wohlelo lwe-IEC62471 kumngcipheko wefotobhayoloji:
I-EN62471 kunye ne-IEC62471 zinemida yokuhlela eyahlukileyo kancinane yomngcipheko we-photobiological, ngolu hlobo lulandelayo:
1. Ngokutsho kwe-EN62471: 2008, i-ultraviolet wavelength iqala kwi-180nm, ngelixa ngokwe-IEC62471: 2006, i-ultraviolet wavelength iqala kwi-200nm;
2, Ixabiso le-S(λ) le-EN62471:2008 lidweliswe kumanyathelo e-1nm, ngelixa i-IEC62471:2006 idweliswe kumanyathelo e-5nm;
3. Kuvavanyo olusondeleyo lwengozi ye-ultraviolet, umda we-Class 0 ingozi (akukho mngcipheko) we-UVA irradiance yi-0,33w / m-2 ngokwe-EN62471: 2008 standard, ngelixa umda we-Class 0 hazard (akukho mngcipheko) we-UVA i-irradiance ngokwe-IEC62471: 2006 umgangatho ngu-10,0w / m-2;
4. Ngomngcipheko wokukhanya okuluhlaza okwesibhakabhaka: uvavanyo lomngcipheko omncinci womthombo wokukhanya (300 - 700nm), umda weClass 0 ingozi (akukho mngcipheko) ngokwe-EN62471: 2008 yi-0,01w / m-2, ngelixa umda we-Class 0 ingozi (akukho mngcipheko) ngokwe-IEC62471: 2006 yi-1,0w / m-2.
Ngokutsho kwe-IEC / EN 62471, imithombo yemitha yokubona ibekwe ngokwamaqela ngokwemingcipheko enokubakho ye-photobiological.Kubaluleke kakhulu kwaye kunenzuzo kubantu ukuhlula imithombo yokukhanya evelisa ukukhanya kwemitha.Ukuba umthombo wokukhanya uhlelwa njengeqela "lokhuseleko" (iqela le-exemption) okanye iqela elinomngcipheko ophantsi (iqela lomngcipheko I), akukho mfuneko yenkcazo eneenkcukacha kwaye kwiimeko ezininzi zovavanyo olubiza kakhulu kwindawo yokusebenza kuba ayinayo i-Photobiological Safety Risks. .
Wellwaywamkela amaso isibane brand edume ngamazwe ngamazwe, kunye nezibane LED ukufuma-ubungqina izibane, isibiyeli LED izibane, izibane LED-uthuli-ubungqina, izibane panel, izibane grille, njl eziveliswe Wellway unako ukuhlangabezana ngokupheleleyo neemfuno zabathengi EN62471:2008 umgangatho.Uvavanyo lokhuseleko lwe-photobiological lwamaso wesibane kunye nezibane zonke zigqithiswa yi-arhente yovavanyo lomntu wesithathu.
