Umutekano wamafoto yumutara

Mu bihe byashize, nta buryo burambuye bwo gupima no gusuzuma ingaruka zatewe n'imirasire y'umucyo ku mubiri w'umuntu. Uburyo bwa gakondo bwo gupima ni ugusuzuma ibiri muri ultraviolet cyangwa urumuri rutagaragara ruri mu mucyo. Kubwibyo, mugihe tekinoroji nshya yo kumurika LED igaragara, dushobora gukoresha gusa IEC / EN 60825 isanzwe nkisuzuma ryibicuruzwa bya laser. IEC / EN 60825 ahanini igerageza ikabara imbaraga z'umucyo umwe. Noneho LED ni urumuri rugari, bityo Standard IEC / EN 60825 ntigikoreshwa kumurika. Kubwibyo, IEC yashyizeho IEC / EN 62471 kugirango igererwe ingaruka.

Intego ya IEC / EN62471 nugusuzuma ingaruka ziterwa nimirasire yumucyo ijyanye namatara atandukanye hamwe na sisitemu yamatara, gusimbuza byimazeyo ibisabwa kurwego rwingufu zibicuruzwa bya LED mubipimo bya IEC / EN60825, ongeraho ibyifuzo bya fotobiologiya, harimo ubukana bwimirasire, urumuri rwinshi, nibindi. ., no gutondekanya ibicuruzwa ukurikije amakuru yikizamini, harimo:

Nta kaga; Icyiciro ard ibyago (ibyago bike); Icyiciro ard ibyago (ibyago bitagereranywa); Icyiciro Ⅲhazard (ibyago byinshi)

Urwego rwo gusonerwa (nta ngaruka): ntiruzatera ingaruka zose ziterwa nimirasire ya fotobiologiya mugihe ntarengwa cyagenwe muriki gipimo.

Icyiciro cya I (ibyago bike): mugihe gisanzwe gikoreshwa, ntabwo bizatera ingaruka ziterwa nimirasire ya fotobiologiya ukurikije imyitwarire isanzwe yabantu.

Icyiciro cya II (ibyago bitagereranywa): ukurikije uburyo butangaje bwo kwirinda amaso yumuntu kumasoko yumucyo mwinshi cyangwa igisubizo kitorohewe nimirasire yumuriro, ntabwo bizatera ingaruka ziterwa nimirasire ya fotobiologiya.

Icyiciro cya III (ibyago byinshi): no kumurika ako kanya bizatera imirase.

Umuryango w’ubumwe bw’ibihugu by’Uburayi EN62471: 2008 washyizwe mu bikorwa kuva ku ya 1 Nzeri 2009, kandi igice cya LED cya EN60825 kizaba kitemewe rwose ku ya 1 Nzeri 2010.

EN 62471 ikubiyemo amabwiriza ya CE yo hasi ya Voltage (Amabwiriza ya LVD 2006/95 / EC) hamwe nubuyobozi bwimirasire yumucyo (AORD 2006/25).

IEC / EN 62471 irakoreshwa kumatara yose hamwe na sisitemu yamatara, harimo LED, amatara yaka, amatara ya fluorescent, amatara asohora gaze, amatara ya arc nandi matara namatara. „

Amabwiriza y’ubumwe bw’ibihugu by’Uburayi 244/2009 ku bijyanye n’ingufu zikenerwa n’amatara yo mu rugo adafite icyerekezo kandi agaragaza ko ikizamini cy’imirasire ya UV kigomba gukorwa hakurikijwe IEC / EN 62471 (cyane cyane ku matara azigama ingufu).

Icyemezo cya CB cyo kwikosora amatara ya LED kigomba kuba gikubiyemo kugerageza umutekano wifotozi ukurikije IEC 62471 na IEC TR 62471-2. Ukurikije icyemezo cya OSM / CTL, amatara ya LED agomba gupimwa hakurikijwe IEC / EN 62471. Ikirango cya LED module yo kurinda amaso yumuntu igomba kwerekeza kuri IEC / EN62471

C. Ingaruka mbi z'imirasire yumucyo kumaso kumaso yumuntu / uruhu

Ibikurikira nimbonerahamwe ntarengwa ya IEC62471 kubibazo byamafoto:

EN62471 na IEC62471 bifite imipaka itandukanye yo gutandukanya ibyago byo gufotora, nkibi bikurikira:

1. Dukurikije EN62471: 2008, uburebure bwa ultraviolet butangirira kuri 180nm, mugihe ukurikije IEC62471: 2006, uburebure bwa ultraviolet butangirira kuri 200nm;

2 value Agaciro S (λ) ka EN62471: 2008 kashyizwe ku ntambwe 1nm, naho IEC62471: 2006 yashyizwe ku ntambwe 5nm;

3. Kubireba hafi ya ultraviolet isuzuma ryibyago, igipimo cyicyiciro cya 0 cyago (ntakibazo) cyumuriro wa UVA ni 0,33w / m-2 ukurikije ibipimo bya EN62471: 2008, mugihe imipaka yicyiciro cya 0 (nta ngaruka) ya UVA imishwarara ukurikije IEC62471: 2006 igipimo ni 10,0w / m-2;

4. Kubibazo byurumuri rwubururu: gusuzuma inkomoko ntoya yumucyo (300 - 700nm), imipaka yicyiciro cya 0 ibyago (nta ngaruka) ukurikije EN62471: 2008 ni 0,01w / m-2, mugihe imipaka yicyiciro cya 0 (nta ngaruka) ukurikije IEC62471: 2006 ni 1,0w / m-2.

Nk’uko IEC / EN 62471 ibivuga, amasoko y’imirasire ya optique akusanyirizwa hamwe akurikije ingaruka zishobora gufotora. Ni ngombwa cyane kandi ni ingirakamaro kubantu gutondekanya amasoko yumucyo atanga imirasire yumucyo. Niba isoko yumucyo ishyizwe mumatsinda "umutekano" (itsinda ryabasonewe) cyangwa itsinda rifite ibyago bike (itsinda ryibyago I), ntihakenewe ibisobanuro birambuye kandi mubihe byinshi byo kwisuzumisha kumurimo uhenze kuko bidafite ingaruka zumutekano wa Photobiologique .

 Murahoifata amasaro azwi cyane ku rwego mpuzamahanga ku matara ya LED, n'amatara ya LED adafite ubuhehere, amatara ya LED, amatara adafite umukungugu, amatara ya paneli, amatara ya grille, nibindi byakozwe na Wellway birashobora kuzuza byuzuye ibisabwa nabakiriya kurwego rwa EN62471: 2008. Igeragezwa ryumutekano wa fotobiologiya yamasaro yamatara namatara byose byanyuze mubigo bishinzwe gupima.
