ʻO ke kūlana palekana Photobiological no nā kukui

I ka wā ma mua, ʻaʻohe ana kikoʻī a me ke ʻano loiloi no ka pōʻino i hana ʻia e ka radiation māmā i ke kino kanaka.ʻO ke ʻano hoʻāʻo maʻamau ka loiloi i ka ʻike o ka ultraviolet a i ʻole ke kukui ʻike ʻole i loko o ka nalu māmā.No laila, ke ʻike ʻia ka ʻenehana kukui LED hou, hiki iā mākou ke hoʻohana i ka maʻamau like IEC / EN 60825 e like me ka loiloi o nā huahana laser.ʻO IEC / EN 60825 ka mea nui e hoʻāʻo a helu i ka ikehu o ka māmā nalu lōʻihi.I kēia manawa ʻo LED kahi kukui ākea ākea, no laila ʻaʻole pili ka Standard IEC / EN 60825 no ke kukui.No laila, ua hoʻokumu ʻo IEC i ka IEC / EN 62471 no ka helu pilikia.

ʻO ke kumu o IEC / EN62471 ka loiloi ʻana i nā pōʻino radiation māmā e pili ana i nā kukui like ʻole a me nā ʻōnaehana kukui, hoʻololi piha i nā koi o ka pae ikehu o nā huahana LED ma IEC / EN60825 maʻamau, hoʻohui i nā koi photobiological, me ka nui o ka radiation, radiation kukui, etc. ., a hoʻokaʻawale i nā huahana e like me ka ʻikepili hōʻike, me:

ʻAʻohe pilikia;Papa Ⅰ pōʻino (ʻemi haʻahaʻa);Papa Ⅱ pōʻino (kūpono kūpono);Papa Ⅲ pōʻino (pilikia kiʻekiʻe)

Ka pae hoʻokuʻu (ʻaʻohe pilikia): ʻaʻole ia e hoʻopilikia i ka radiation photobiological ma lalo o nā kūlana palena i kuhikuhi ʻia i kēia maʻamau.

Papa I (pilikia haʻahaʻa): ma lalo o nā kūlana hoʻohana maʻamau, ʻaʻole ia e hoʻopōʻino i ka pāhawewe photobiological e like me ke ʻano kukui maʻamau o nā kānaka.

Papa II (pilikia haʻahaʻa): e like me ka ʻalo ʻana o nā maka kanaka i nā kumu kukui ʻālohilohi a i ʻole ka pane ʻoluʻolu ʻole o ka radiation thermal, ʻaʻole ia e hoʻopilikia i nā pōʻino photobiological.

Papa III (pilikia kiʻekiʻe): ʻo ka hoʻomālamalama koke ʻana e hoʻopilikia i ka radiation.

ʻO ka EU maʻamau EN62471: 2008 ua hoʻokō ʻia mai Kepakemapa 1, 2009, a ʻo ka ʻāpana LED o EN60825 e ʻole loa i ka lā 1 Kepakemapa 2010.

Ua uhi ʻia ʻo EN 62471 e ka CE Low Voltage Directive (LVD Directive 2006 / 95 / EC) a me ke kuhikuhi ʻana i ka radiation light artificial (AORD 2006 / 25).

Hoʻopili ʻia ʻo IEC / EN 62471 i nā kukui āpau a me nā ʻōnaehana kukui, me nā LED, nā ʻōpala incandescent, nā kukui fluorescent, nā kukui hoʻokuʻu kino, nā kukui arc a me nā kukui ʻē aʻe a me nā kukui.„

ʻO ke kānāwai EU 244 / 2009 e pili ana i ka pono o ka ikehu o nā kukui non directional home e kuhikuhi pū ana i ka hoʻāʻo ʻana i ka radiation UV pono e hana ʻia e like me IEC / EN 62471 (ka mea nui no nā kukui mālama ola).

ʻO ka hōʻoia ʻana o CB no ka hoʻoponopono pono ʻana i nā kukui LED pono e hoʻāʻo i ka palekana photobiological e like me IEC 62471 a me IEC TR 62471-2.Wahi a OSM / CTL hoʻonā, pono e hoʻāʻo ʻia nā kukui LED e like me IEC / EN 62471. ʻO ka lepili o ka module LED no ka pale ʻana i nā maka kanaka e pili i IEC / EN62471

Nā hopena maikaʻi ʻole o ka palekana photobiological ma nā maka / ʻili kanaka

C. Nā hopena maikaʻi ʻole o ka pāhawewe māmā i ka mālamalama ma nā maka / ʻili kanaka

Eia ka papa helu palena palena o IEC62471 no ka pilikia photobiological:

ʻO EN62471 a me IEC62471 nā palena hoʻokaʻawale ʻokoʻa no ka pilikia photobiological, penei:

1. Wahi a EN62471: 2008, hoʻomaka ka hawewe ultraviolet mai 180nm, ʻoiai e like me IEC62471: 2006, hoʻomaka ka hawewe ultraviolet mai 200nm;

2、Ua helu ʻia ka waiwai S(λ) o EN62471:2008 ma nā ʻanuʻu 1nm, ʻoiai ʻo IEC62471:2006 i helu ʻia ma nā ʻanuʻu 5nm;

3. No ka loiloi kokoke i ka ultraviolet, ʻo ka palena o ka papa 0 pilikia (ʻaʻohe pilikia) o ka irradiance UVA he 0,33w / m-2 e like me EN62471:2008 maʻamau, ʻoiai ka palena o ka papa 0 pilikia (ʻaʻohe pilikia) o UVA irradiance e like me IEC62471: 2006 maʻamau ka 10,0w / m-2;

4. No ka pōʻino o ke kukui polū: ka loiloi kumu kumu kukui liʻiliʻi (300 – 700nm), ʻo ka palena o ka papa 0 pilikia (ʻaʻohe pilikia) e like me EN62471: 2008 ʻo 0,01w / m-2, ʻoiai ka palena o ka Class 0 hazard (ʻaʻohe pilikia) e like me IEC62471: 2006 ʻo 1,0w / m-2.

Wahi a IEC / EN 62471, ua hui pū ʻia nā kumu radiation optical e like me ko lākou mau pilikia photobiological.He mea koʻikoʻi a pono i ka poʻe ke hoʻokaʻawale i nā kumu kukui e hoʻopuka ai i ka radiation māmā.Inā hoʻokaʻawale ʻia ke kumu kukui ma ke ʻano he pūʻulu "palekana" (hui hoʻokuʻu) a i ʻole he pūʻulu haʻahaʻa (pilikia I), ʻaʻohe pono no kahi kikoʻī a ma ka hapa nui o ka loiloi wahi hana no ka mea ʻaʻohe Photobiological Safety Risks .

 Wellwayhoʻohana i nā lei kukui LED kaulana ma waena o ka honua, a me nā kukui moist-proof LED, nā kukui bracket LED, nā kukui pale lepo, nā kukui panel, nā kukui grille, a me nā mea i hana ʻia e Wellway hiki ke hoʻokō piha i nā koi o nā mea kūʻai no EN62471: 2008 maʻamau.ʻO ka hoʻāʻo palekana photobiological o nā lei kukui a me nā kukui ua hoʻoholo ʻia e nā ʻoihana hoʻāʻo ʻekolu.
