Esikhathini esedlule, ibingekho indlela yokulinganisa enemininingwane nokuhlola umonakalo odalwe imisebe yokukhanya emzimbeni womuntu.Indlela yokuhlola evamile ukuhlola okuqukethwe kwe-ultraviolet noma ukukhanya okungabonakali okuqukethwe kumaza okukhanya.Ngakho-ke, lapho ubuchwepheshe obusha bokukhanyisa kwe-LED buvela, singasebenzisa i-IEC/EN 60825 efanayo kuphela njengokuhlolwa kwemikhiqizo ye-laser.I-IEC / EN 60825 ihlola ikakhulukazi futhi ibale amandla okukhanya kwe-wavelength eyodwa.Manje i-LED iyibhendi ebanzi yokukhanya, ngakho i-Standard IEC / EN 60825 ayisasebenzi ekukhanyisweni.Ngakho-ke, i-IEC yakhe i-IEC / EN 62471 yokulinganisa ubungozi.
Inhloso ye-IEC / EN62471 ukuhlola izingozi zemisebe yokukhanya ezihlobene nezibani ezahlukene nezinhlelo zezibani, ukufaka esikhundleni ngokuphelele izidingo ezingeni lamandla lemikhiqizo ye-LED ku-IEC / EN60825 standard, ukwengeza izidingo ze-photobiological, okuhlanganisa ukuqina kwemisebe, ukukhanya kwemisebe, njll. ., futhi uhlukanise imikhiqizo ngokwedatha yokuhlola, okuhlanganisa:
Ayikho ingozi;Ingozi yekilasi Ⅰ (ingozi ephansi);Ingozi yekilasi Ⅱ (ingozi emaphakathi);Isigaba Ⅲingozi (ingozi ephezulu)
Ileveli yokukhululwa (ayikho ingozi): ngeke ibangele noma iyiphi ingozi yemisebe ye-photobiological ngaphansi kwemibandela yomkhawulo eshiwo kuleli zinga.
Ikilasi I (ingozi ephansi): ngaphansi kwezimo ezijwayelekile zokusetshenziswa, ngeke ibangele izingozi zemisebe ye-photobiological ngokuya ngokuziphatha kwabantu okujwayelekile kokukhanyisa.
Isigaba II (ingozi emaphakathi): ngokuya ngokugwema okukhazimulayo kwamehlo omuntu ukuya emithonjeni yokukhanya ephezulu noma ukusabela okungemnandi kwemisebe eshisayo, ngeke kubangele izingozi zemisebe ye-photobiological.
I-Class III (ingozi enkulu): ngisho nokukhanya okusheshayo kuzodala ingozi yemisebe.
Izinga le-EU EN62471:2008 seliqalisiwe kusukela ngoSepthemba 1, 2009, futhi ingxenye ye-LED ye-EN60825 izobe ingasavumelekile ngokuphelele ngoSepthemba 1, 2010.
I-EN 62471 imbozwe yi-CE Low Voltage Directive (LVD Directive 2006 / 95 / EC) kanye ne-artificial light radiation Directive (AORD 2006/25).
I-IEC / EN 62471 isebenza kuzo zonke izinhlelo zamalambu namalambu, okuhlanganisa ama-LED, ama-incandescent bulb, amalambu e-fluorescent, amalambu akhipha igesi, ama-arc amalambu nezinye izibani nezibani.
Umthetho we-EU 244/2009 wezidingo zokonga ugesi wamalambu angaqondisiwe futhi ucacisa ukuthi ukuhlolwa kwemisebe ye-UV kumele kwenziwe ngokuhambisana ne-IEC / EN 62471 (ikakhulukazi izibani ezonga amandla).
Ukuqinisekiswa kwe-CB kwezibani ze-LED ezizilungisayo kufanele kubandakanye ukuhlolwa kokuphepha kwe-photobiological ngokuhambisana ne-IEC 62471 kanye ne-IEC TR 62471-2.Ngokuvumelana nesinqumo se-OSM / CTL, izibani ze-LED kufanele zihlolwe ngokuya nge-IEC / EN 62471. Ilebula lemojuli ye-LED yokuvikela iso lomuntu izobhekisela ku-IEC / EN62471

Okulandelayo yithebula lomkhawulo wokuhlukaniswa kwe-IEC62471 ngengozi ye-photobiological:
I-EN62471 kanye ne-IEC62471 inemikhawulo yezigaba ehluke kancane yengozi ye-photobiological, kanjena:
1. Ngokuka-EN62471:2008, ubude begagasi be-ultraviolet buqala ku-180nm, kuyilapho ngokusho kwe-IEC62471:2006, ubude begagasi be-ultraviolet buqala ukusuka ku-200nm;
2, Inani le-S(λ) lika-EN62471:2008 lifakwe kuhlu lwezinyathelo ezingu-1nm, kuyilapho i-IEC62471:2006 ifakwe kuhlu lwezinyathelo ezingu-5nm;
3. Ekuhlolweni kwengozi okuseduze kwe-ultraviolet, umkhawulo we-Class 0 wengozi (ayikho ingozi) ye-UVA irradiance ngu-0,33w / m-2 ngokwezinga le-EN62471:2008, kuyilapho umkhawulo we-Class 0 ingozi (ayikho ingozi) ye-UVA. i-irradiance ngokuya nge-IEC62471:2006 ejwayelekile ngu-10,0w / m-2;
4. Ngengozi yokukhanya okuluhlaza okwesibhakabhaka: ukuhlolwa kwengozi yomthombo wokukhanya omncane (300 – 700nm), umkhawulo wengozi Yekilasi 0 (ayikho ingozi) ngokuya nge-EN62471:2008 ngu-0,01w / m-2, kuyilapho umkhawulo wengozi Yekilasi 0 (ayikho ingozi) ngokuya nge-IEC62471:2006 ingu-1,0w / m-2.
Ngokusho kwe-IEC / EN 62471, imithombo yemisebe ye-optical ihlanganiswa ngokuya ngezingozi ezingaba khona ze-photobiological.Kubaluleke kakhulu futhi kunenzuzo ukuthi abantu bahlukanise imithombo yokukhanya ekhiqiza imisebe yokukhanya.Uma umthombo wokukhanya uhlukaniswa njengeqembu "lokuphepha" (iqembu lokukhululwa) noma iqembu elinobungozi obuncane (iqembu lengozi I), asikho isidingo semininingwane enemininingwane futhi ezimweni eziningi zokuhlola okumba eqolo kwendawo yokusebenza ngoba ayinazo Izingozi Zokuphepha Nge-Photobiological. .
Wellwayyamukela ubuhlalu belambu le-LED elidumile emhlabeni wonke, kanye nezibani ze-LED ezivikela umswakama, izibani ze-LED ezivikela uthuli, izibani zephaneli, amalambu e-grille, njll. okukhiqizwa yi-Wellway kungahlangabezana ngokugcwele nezidingo zamakhasimende ze-EN62471:2008 ejwayelekile.Ukuhlolwa kokuphepha kwe-photobiological yobuhlalu bamalambu namalambu konke kudluliswa yi-ejensi yokuhlola evela eceleni.
