Photobiological kuchengetedza mwero wemarambi

Munguva yakapfuura, pakanga pasina kuyerwa kwakadzama uye nzira yekuongorora yekukuvadza kunokonzerwa nemwaranzi yemwenje kumuviri wemunhu. Iyo yechinyakare bvunzo nzira ndeyekuongorora zvirimo muultraviolet kana mwenje usingaonekwe uri mumwenje wave. Naizvozvo, kana tekinoroji nyowani yemwenje ye LED ichionekwa, isu tinogona chete kushandisa yakafanana chiyero IEC / EN 60825 sekuongororwa kwezvigadzirwa zvelaser. IEC / EN 60825 inonyanya kuyedza uye kuverengera simba reimwe wavelength mwenje. Ikozvino LED ibhendi rakakura bhendi, saka iyo Standard IEC / EN 60825 haichashandi pakuvheneka. Naizvozvo, IEC yakagadzira IEC / EN 62471 yekuyera njodzi.

Chinangwa cheIEC / EN62471 ndechekuongorora njodzi dzemwenje dzemwenje dzine chekuita nemarambi akasiyana uye masisitimu emwenje, kutsiva zvizere zvinodikanwa pachiyero chesimba rezvigadzirwa zve LED muIEC / EN60825 standard, kuwedzera photobiological zvinodiwa, kusanganisira kusimba kwemwaranzi, kupenya kwemwaranzi, nezvimwe. ., uye sarudza zvigadzirwa zvinoenderana nedata rekuyedza, kusanganisira:

Hapana ngozi; Kirasi Ⅰ njodzi (yakaderera njodzi); Kirasi Ⅱ njodzi (ngozi ine mwero); Kirasi Ⅲ njodzi (yakanyanya njodzi)

Chiyero chekuregererwa (hapana njodzi): hazvizokonzerese chero photobiological radiation njodzi pasi pemiganho yemamiriro akatsanangurwa mune iyi chiyero.

Kirasi I (yakaderera njodzi): pasi pemamiriro ekushandiswa akajairwa, haizokonzerese njodzi yemwaranzi yephotobiological zvinoenderana nemaitiro akajairika evanhu.

Kirasi II (njodzi iri pakati nepakati): zvinoenderana nekudzivirira kunoshamisa kwemaziso evanhu kune kupenya kwakanyanya kwemwenje masosi kana mhinduro isina kugadzikana yemwaranzi yekupisa, hazvizokonzeresa njodzi yeradiobiological radiation.

Kirasi III (yakanyanya njodzi): kunyangwe kuvhenekerwa nekukasira kuchakonzera njodzi yemwaranzi.

Muyero weEU EN62471:2008 wakaitwa kubva munaGunyana 1, 2009, uye chikamu che LED che EN60825 chichave chisina kushanda zvachose munaGunyana 1, 2010.

EN 62471 inofukidzwa neEC Low Voltage Directive (LVD Directive 2006 / 95 / EC) uye artificial light radiation dhairekitori (AORD 2006 / 25).

IEC / EN 62471 inoshanda kune ese marambi uye mwenje masisitimu, anosanganisira ma LED, incandescent bulbs, fluorescent mwenje, gasi rekuburitsa marambi, arc mwenje nemamwe marambi nemarambi.

EU regulation 244 / 2009 pane zvinodikanwa zvesimba remagetsi emumba asiri ekutungamira mwenje zvakare inotsanangura kuti bvunzo paradio yeUV inofanirwa kuitwa zvinoenderana neIEC / EN 62471 (kunyanya yemarambi ekuchengetedza simba).

Chitupa cheCB chekuzvigadzirisa wega marambi e LED kunofanirwa kusanganisira kuyedzwa kwekuchengetedza mafotobiological zvinoenderana neIEC 62471 uye IEC TR 62471-2. Zvinoenderana neOSM / CTL resolution, marambi e LED anofanirwa kuyedzwa zvinoenderana neIEC / EN 62471. Iyo label ye LED module yekudzivirira ziso remunhu ichareva IEC / EN62471

Inotevera tafura yekugadzika tafura yeIEC62471 yengozi yefotobiological:

EN62471 uye IEC62471 vane zviganho zvakasiyana zvishoma zvengozi yefotobiological, sezvinotevera:

1. Maererano ne EN62471: 2008, iyo ultraviolet wavelength inotanga kubva ku180nm, nepo maererano neIEC62471: 2006, iyo ultraviolet wavelength inotanga kubva ku200nm;

2, The S(λ) kukosha kweEN62471:2008 yakanyorwa mumatanho e1nm, nepo IEC62471:2006 yakanyorwa mumatanho e5nm;

3. Kana iri pedyo neultraviolet risk assessment, muganho weClass 0 hazard (hapana ngozi) yeUVA irradiance i0,33w / m-2 maererano neEN62471:2008 standard, nepo muganhu weClass 0 hazard (hapana ngozi) yeUVA. irradiance maererano neIEC62471: 2006 chiyero ndeye 10,0w / m-2;

4. Panjodzi yechiedza cheblue: diki light source risk assessment (300 – 700nm), muganho weClass 0 hazard (hapana njodzi) zvinoenderana neEN62471:2008 ndeye 0,01w / m-2, nepo muganho weClass 0 ngozi. (hapana njodzi) maererano neIEC62471:2006 ndeye 1,0w / m-2.

Zvinoenderana neIEC / EN 62471, optical radiation masosi akaiswa mumapoka zvichienderana neanogona kuitika mafotobiological njodzi. Zvakanyanya kukosha uye zvinobatsira kuti vanhu vagoronga zvitubu zvemwenje zvinoburitsa mwaranzi yemwenje. Kana iyo mwenje sosi ichirondedzerwa se "chengetedzo" boka (boka rekuregererwa) kana boka rine njodzi yakaderera (risk boka I), hapana chikonzero cheruzivo rwakadzama uye kazhinji rwekudhura kwenzvimbo yebasa yekuongorora nekuti haina Photobiological Safety Risks. .
