Waagii hore, ma jirin hab faahfaahsan oo cabbiraadda iyo qiimaynta waxyeelada ay u geystaan shucaaca iftiinka jidhka bini'aadamka. Habka tijaabada dhaqameedku waa in la qiimeeyo waxa ku jira ultraviolet ama iftiinka aan la arki karin ee ku jira hirarka iftiinka. Sidaa darteed, marka tignoolajiyada cusub ee iftiinka LED ay soo baxdo, waxaan kaliya u isticmaali karnaa isla heerka IEC / EN 60825 sida qiimeynta alaabada laysarka. IEC / EN 60825 inta badan waxay tijaabisaa oo xisaabisaa tamarta iftiinka hirarka. Hadda LED waa laydh ballaadhan oo ballaadhan, markaa Heerka IEC / EN 60825 hadda lama dabaqi karo iftiinka. Sidaa darteed, IEC waxay u dejisay IEC / EN 62471 qiimeynta halista.
Ujeedada IEC / EN62471 waa in la qiimeeyo khatarta shucaaca iftiinka ee la xidhiidha nalalka kala duwan iyo nidaamyada nalalka, si buuxda u beddelo shuruudaha heerka tamarta ee alaabta LED ee heerka IEC / EN60825, ku dar shuruudaha sawir-biological, oo ay ku jiraan xoojinta shucaaca, dhalaalka shucaaca, iwm. ., oo u kala saar alaabta si waafaqsan xogta tijaabada, oo ay ku jiraan:
Khatar ma leh; Heerka Ⅰ khatarta (khatarta hoose); Heerka Ⅱ khatarta (khatar dhexdhexaad ah); Heerka Ⅲhazard (khatarta sare)
Heerka ka-dhaafitaanka (khatar ma leh): ma keeni doonto wax khatar ah shucaaca sawir-bioloji iyadoo hoos timaada shuruudaha xaddidan ee lagu qeexay heerkan.
Fasalka I (khatarta hoose): xaaladaha isticmaalka caadiga ah, ma keeni doonto khataraha shucaaca sawir-bioloji iyadoo loo eegayo dabeecadda iftiinka caadiga ah ee dadka.
Fasalka II (khatar dhexdhexaad ah): marka loo eego ka fogaanshiyaha quruxda badan ee indhaha bini'aadamka ilaa ilaha iftiinka iftiinka sare ama jawaabta aan fiicnayn ee shucaaca kulaylka, ma keeni doonto khataraha shucaaca sawir-bioloji.
Fasalka III (khatar sare): xitaa iftiinka degdega ah wuxuu keeni doonaa khatarta shucaaca.
Halbeegga EU EN62471:2008 waxa la hirgaliyay ilaa Sebtembar 1, 2009, iyo qaybta LED ee EN60825 waxa ay gabi ahaanba shaqayn doontaa Sebtember 1, 2010.
EN 62471 waxaa daboolaya dardaaranka korantada hooseeya ee CE (Dardaaranka LVD 2006/95 / EC) iyo dardaaranka shucaaca iftiinka macmalka ah (AORD 2006/25).
IEC / EN 62471 waxay khuseysaa dhammaan nalalka iyo nidaamyada nalalka, oo ay ku jiraan LEDs, nalalka iftiinka, nalalka dhaadheer, nalalka gaaska, nalalka arc iyo nalalka kale. "
Xeerarka EU 244/2009 ee shuruudaha hufnaanta tamarta ee nalalka guriga ee aan jihaynta lahayn ayaa sidoo kale qeexaya in tijaabada shucaaca UV loo baahan yahay in lagu fuliyo si waafaqsan IEC / EN 62471 (badanaa nalalka tamarta kaydiya).
Shahaadada CB ee nalalka LED-ka ee iskood isku hagaajiya waa inay ku jiraan tijaabinta badbaadada sawir-biological iyadoo la raacayo IEC 62471 iyo IEC TR 62471-2. Marka loo eego xallinta OSM / CTL, nalalka LED-ka waa in la tijaabiyaa si waafaqsan IEC / EN 62471. Calaamadda moduleka LED ee ilaalinta indhaha aadanaha waa inay tixraacdaa IEC / EN 62471

Kuwa soo socdaa waa shaxda xadka kala soocida ee IEC62471 khatarta sawir-bioloji:
TS EN 62471 iyo IEC62471 waxay leeyihiin xaddidaadyo kala duwanaansho yar oo kala duwan oo loogu talagalay khatarta sawir-bioloji, sida soo socota:
1. Marka loo eego EN62471: 2008, hirarka ultraviolet wuxuu ka bilaabmaa 180nm, halka marka loo eego IEC62471: 2006, hirarka ultraviolet wuxuu ka bilaabmaa 200nm;
2. Qiimaha S(λ) ee EN62471:2008 waxa ay ku taxan yihiin 1nm tillaabooyinka, halka IEC62471:2006 lagu taxay tallaabooyinka 5nm;
3. Qiimaynta khatarta ultraviolet ee u dhow, xadka heerka 0 khatarta ah (khatar malahan) ee shucaaca UVA waa 0,33w / m-2 marka loo eego heerka EN62471: 2008, halka xadka heerka 0 ee khatarta ah (khatar malahan) UVA IEC62471: 2006 heerka waa 10,0w / m-2;
4. Khatarta iftiinka buluuga ah: Qiimaynta khatarta isha iftiinka yar (300 - 700nm), xadka heerka 0 khatarta (khatar malahan) marka loo eego EN62471: 2008 waa 0,01w / m-2, halka xadka heerka heerka 0 (khatar malahan) marka loo eego IEC62471:2006 waa 1,0w/m-2.
Marka loo eego IEC / EN 62471, ilaha shucaaca indhaha ayaa loo qaybiyaa iyadoo loo eegayo khatarahooda sawir-biological. Aad bay muhiim u tahay oo faa'iido u leedahay dadku inay kala saaraan ilaha iftiinka ee soo saara shucaaca iftiinka. Haddii isha iftiinka loo kala saaro koox "nabadgelyo" (koox ka-dhaafitaan) ama koox khatar yar (kooxda halista I), looma baahna faahfaahin faahfaahsan iyo inta badan kiisaska qaaliga ah ee goobta shaqada sababtoo ah ma laha Khatarta Badbaadada Sawir-biological .
Waa hagaagWaxay qabataa calaamadda caalamiga ah ee caanka ah ee caanka ah ee nalalka LED-ka, iyo nalalka LED-ga ee qoyan, nalalka LED-ka, nalalka LED-ka ee boodhka, nalalka ay soo saarto Wellway waxay si buuxda u buuxin kartaa shuruudaha macaamiisha ee EN62471: 2008 heerka. Tijaabada badbaadada sawir-bioloji ee kuulka laambada iyo laambada waxaa dhammaan mara hay'adda baaritaanka qolo saddexaad.
