Mbere yo kugura itara ryameza, usibye gusuzuma ibisobanuro, imikorere, hamwe nibikoreshwa, kugirango ubungabunge umutekano, ntukirengagize ikimenyetso cyemeza kubipfunyika hanze.Ariko, hariho ibimenyetso byinshi byemeza amatara yo kumeza, bivuze iki?
Kugeza ubu, amatara hafi ya yose ya LED arakoreshwa, yaba amatara cyangwa amatara.Mubihe byashize, ibyinshi mubitekerezo bya LED byari kumatara yerekana n'amatara yumuhanda wibicuruzwa bya elegitoroniki, kandi ntibikunze kwinjira mubuzima bwacu bwa buri munsi.Nyamara, uko ikoranabuhanga rimaze gukura mu myaka yashize, hagaragaye amatara menshi ya LED n'amatara yo ku meza, n'amatara yo ku mihanda n'amatara y'imodoka yagiye asimburwa n'amatara ya LED.Muri byo, amatara ya LED yamashanyarazi afite ibiranga kuzigama ingufu, kuramba, umutekano, kugenzura ubwenge, no kurengera ibidukikije.Bafite ibyiza byinshi kuruta amatara gakondo.Kubwibyo, amatara menshi kumeza kumasoko akoresha amatara ya LED.
Nyamara, amatara menshi kumeza kumasoko yamamaza ibintu nkibidafite flicker, anti-glare, bizigama ingufu, kandi nta byangiza ubururu.Ibi ni ukuri cyangwa ni ibinyoma?Witondere guhumura amaso yawe hanyuma urebe icyemezo cya label kugirango ugure itara ryameza rifite ireme n'umutekano byemewe.
Kubyerekeye "Ibipimo byumutekano byamatara":
Mu rwego rwo kurengera uburenganzira n’inyungu z’abaguzi, ibidukikije, umutekano, n’isuku, no gukumira ibicuruzwa bito byinjira ku isoko, guverinoma zo mu bihugu bitandukanye zifite gahunda zerekana ibimenyetso zishingiye ku mategeko n’ibipimo mpuzamahanga.Iri ni itegeko ryumutekano riteganijwe muri buri karere.Nta bipimo by’umutekano byanyuze kuri buri gihugu.Zhang ntashobora kwinjira mukarere kugurisha byemewe.Binyuze kuri ayo matara asanzwe, uzabona ikimenyetso gihuye.
Ku bijyanye n’umutekano w’amatara, ibihugu bifite amazina n’amabwiriza atandukanye, ariko muri rusange amabwiriza ashyirwaho hakurikijwe amahame amwe mpuzamahanga ya IEC (Komisiyo mpuzamahanga y’ikoranabuhanga).Muri EU, ni CE, Ubuyapani ni PSE, Amerika ni ETL, naho mu Bushinwa ni icyemezo cya CCC (kizwi kandi nka 3C).
CCC iteganya ibicuruzwa bigomba kugenzurwa, ukurikije ibisobanuro bya tekiniki, inzira zishyirwa mu bikorwa, ikimenyetso kimwe, n'ibindi. Birakwiye ko tumenya ko ibyo byemezo bidatanga ubuziranenge, ariko nibirango byibanze byumutekano.Ibirango byerekana uwabikoze wenyine-yerekana ko ibicuruzwa byayo byubahiriza amabwiriza yose abigenga.
Muri Reta zunzubumwe za Amerika, UL (Underwriters Laboratories) n’umuryango munini wigenga kwisi kwipimisha no kumenyekanisha umutekano.Irigenga, idaharanira inyungu, kandi ishyiraho ibipimo byumutekano rusange.Iki nicyemezo cyubushake, ntabwo ari itegeko.Icyemezo cya UL gifite icyizere cyinshi kandi kimenyekana cyane kwisi.Bamwe mubaguzi bafite ubumenyi bukomeye bwibicuruzwa bazitondera cyane niba ibicuruzwa bifite icyemezo cya UL.
Ibipimo byerekeranye na voltage:
Ku bijyanye n'umutekano w'amashanyarazi w'amatara, buri gihugu gifite amabwiriza yacyo.Icyamamare cyane ni EU LVD Amashanyarazi Mucyo, agamije kurinda umutekano wamatara yintebe iyo akoreshejwe.Ibi kandi bishingiye ku bipimo bya tekiniki bya IEC.
Kubireba ibipimo bike bya flicker:
"Low flicker" bivuga kugabanya umutwaro uterwa no guhindagurika kumaso.Strobe ninshuro yumucyo uhinduka hagati yamabara atandukanye numucyo mugihe.Mubyukuri, flickers zimwe, nk'amatara yimodoka ya polisi no kunanirwa kw'itara, dushobora kubibona neza;ariko mubyukuri, amatara yintebe byanze bikunze ahindagurika, ni ikibazo cyo kumenya niba uyakoresha ashobora kubyumva.Ingaruka zishobora guterwa na flash yumurongo mwinshi zirimo: igicuri cyifotora, kubabara umutwe no kugira isesemi, umunaniro wamaso, nibindi.
Nkuko bigaragara kuri interineti, flicker irashobora kugeragezwa hakoreshejwe kamera ya terefone igendanwa.Icyakora, nk’uko byatangajwe n’ikigo cy’igihugu gishinzwe ubuziranenge bw’amashanyarazi ya Beijing, Ikigo cy’ubugenzuzi n’ubugenzuzi, kamera ya terefone igendanwa ntishobora gusuzuma flicker / stroboscopic y’ibicuruzwa bya LED.Ubu buryo ntabwo ari siyansi.
Kubwibyo, nibyiza kohereza ku rwego mpuzamahanga IEEE PAR 1789 icyemezo gito-flicker.Amatara mato mato mato anyura IEEE PAR 1789 nibyiza.Hano hari ibipimo bibiri byo gupima strobe: Ijanisha rya Flicker (igipimo cya flicker, igabanuka ryagaciro, ryiza) na Frequency (igipimo cya flicker, igiciro kinini, cyiza, nticyoroshye kubonwa nijisho ryumuntu).IEEE PAR 1789 ifite formulaire yo kubara inshuro.Niba flash itera kwangirika, hasobanuwe ko urumuri rusohoka inshuro zirenga 3125Hz, nurwego rutabangamiye, kandi nta mpamvu yo kumenya igipimo cya flash.
. rwose, bivuze ko itara riri murwego rwose rwumutekano wa strobe)
Icyemezo kijyanye nubururu bwubururu
Hamwe niterambere rya LED, ikibazo cyumucyo wubururu nacyo cyakomeje kwitabwaho.Hariho amahame abiri afatika: IEC / EN 62471 na IEC / TR 62778. IEC / EN 62471 y’umuryango w’ubumwe bw’ibihugu by’i Burayi ni ibizamini byinshi byangiza imishwarara ya optique kandi ni nacyo gisabwa kugira ngo itara ryujuje ibyangombwa.Komisiyo mpuzamahanga y’amashanyarazi IEC / TR 62778 yibanze ku isuzuma ry’ubururu bw’ubururu bw’amatara kandi rigabanya ingaruka z’umucyo mu matsinda ane kuva RG0 kugeza RG3:
RG0 - Nta ngaruka za Photobiohazard mugihe igihe cyo kwihererana kirenze amasegonda 10,000, kandi nta kirango gikenewe.
RG1- Ntabwo ari byiza kureba mu buryo butaziguye isoko yumucyo igihe kirekire, kugeza amasegonda 100 ~ 10,000.Nta kimenyetso gikenewe.
RG2-Ntabwo bikwiye kureba mu buryo butaziguye isoko yumucyo, ntarengwa amasegonda 0.25 ~ 100.Imiburo yo kwitondera igomba gushyirwaho ikimenyetso.
RG3-Kureba mu buryo butaziguye isoko yumucyo nubwo muri make (<amasegonda 0.25) ni akaga kandi hagomba kugaragara umuburo.
Kubwibyo, birasabwa kugura amatara yintebe yubahiriza byombi IEC / TR 62778 nta byago na IEC / EN 62471.
Ikirango kijyanye n'umutekano wibintu
Umutekano wibikoresho byamatara kumeza ni ngombwa cyane.Niba ibikoresho byo gukora birimo ibyuma biremereye nka gurş, kadmium, na mercure, bizangiza umubiri wumuntu.Izina ryuzuye rya EU RoHS (2002/95 / EC) ni "Amabwiriza yo Kubuza no Kubuza Ibintu Byangiza mu bicuruzwa by'amashanyarazi na elegitoroniki".Irinda ubuzima bwabantu mu kugabanya ibintu byangiza ibicuruzwa kandi ikanatanga imyanda ikwiye kugirango irengere ibidukikije..Birasabwa kugura amatara yintebe atambutsa aya mabwiriza kugirango umutekano wibikoresho bisukure.
Ibipimo kumirasire ya electronique
Imashanyarazi ya elegitoroniki (EMF) irashobora gutera umutwe, kuruka, leukemia yo mu bwana, ibibyimba bibi byubwonko bikuze nizindi ndwara mumubiri wumuntu, bigira ingaruka cyane kubuzima.Kubwibyo rero, kugirango urinde umutwe wumuntu nu mubiri byerekanwa n’itara, amatara yoherejwe mu bihugu by’Uburayi agomba gusuzumwa ku gahato kugira ngo yipimishe EMF kandi agomba kubahiriza ibipimo bihuye na EN 62493.
Ikimenyetso mpuzamahanga cyemeza ni cyiza cyemeza.Nubwo amatangazo yamamaza atezimbere imikorere yibicuruzwa, ntishobora kugereranywa no kwizerwa hamwe nikimenyetso cyemewe.Noneho, hitamo ibicuruzwa bifite ibimenyetso byemeza mpuzamahanga kugirango wirinde gushukwa no gukoreshwa nabi.Amahoro menshi yo mumutima nubuzima.
