Indasitiri ye LED iindasitiri yenyika ichiri kusimukira, uye sosi yemwenje ye LED ndiyo inonyanya kuvimbisa mwenje mutsva muzana ramakore rechi 21, asi nekuti tekinoroji ye LED ichiri mudanho rekukura rekuenderera mberi kwekukura, indasitiri ichine mibvunzo yakawanda pamusoro pechiedza chayo. hunhu, bepa rino richabatanidza dzidziso nekuita, ongorora mamiriro azvino e LED uye ramangwana rekusimudzira kutungamira, kusimudzira hutano hwekusimudzira indasitiri ye LED.

LED indasitiri yekuvandudza mamiriro uye maitiro

a.Kubva pakuona kwekutenderera kwechigadzirwa, mwenje we LED wapinda munguva yakakura kwazvo.

Parizvino, mwenje we LED, ungave mumwenje wekunze, kana nzvimbo yekuvhenekesa yekutengeserana, iri kupinda nechiyero chinotyisa.

Asi panguva ino, nzvimbo yemwenje yemumba inogona kutsanangurwa sebhegi rakasanganiswa, yakaderera-yekupedzisira, yakaderera-mhando yemhando yemwenje ye LED zvigadzirwa zvinogona kuoneka kwese.Mwenje ye LED ichiri yakanamatira mukuchengetedza simba, kuchengetedza kwezvakatipoteredza uye hupenyu hurefu hwemarambi.Naizvozvo, izvi zvakare zvinotungamira kune vazhinji vanogadzira mwenje we LED kuti vatevedzere yakakwirira-inopenya kushanda uye yakaderera mutengo kukwikwidza, uku vachiregeredza iyo LED kune hutano hwevanhu uye nyaradzo uye nehungwaru hwekuvhenekesa maficha epamusoro-level application.

b.Ndeipi nhungamiro yeramangwana yeindasitiri yeLED?

Kubudirira kwechiedza kucharamba kuchikwira nekugadzirwa kwezvinhu, inova nzira isingadzivisiki yekugadzirwa kwezvinhu, munguva ye LED-inotungamirirwa nemwenje, nokuti chiedza chechiedza chine zvakasiyana-siyana zvepurasitiki, kutsvaga kwehutano hwechiedza huri kuwedzera zvakare.

Kubva pakuona kwese, iyo indasitiri yeLED parizvino iri mudanho rekusimudzira, hapasisina tekinoroji inotungamira kune indasitiri inobatanidzwa muhondo yemitengo, muhondo yemitengo inowedzera kuchena-kupisa, kumanikidza musika kune mhando, hungwaru uye zvimwe. nzira.

Chii chinonzi "chiedza" nemhando?

Kare, mwenje ye LED inopenya, yakagadzikana inopenya inoshanda, nezvimwewo, imhando yakanaka mwenje.Mazuva ano, nepfungwa yekuvhenekesa kwegirinhi uye yakadzika midzi mumoyo yevanhu, chiyero chetsanangudzo yemhando yepamusoro yechiedza chachinja.

a.Chinhanho chekukunda nehuwandu chapfuura, uye nguva yekukunda nemhando yasvika.

Patinoshandira vatengi vekuNorth America, takaona kuti zvavanoda zvemhando yemwenje ye LED zviri kuwedzera nekukwira.Iyo North American Lighting Commission IES yakajekesa nzira itsva yekuongorora TM-30 yekugona kupa ruvara rwezvitubu zvemwenje, ichikurudzira maviri matsva ebvunzo indexes Rf neRg, iyo inoratidza zvizere kuti vamwe vepasirese vari kusundira mberi tsvakiridzo yemwenje ye LED.Blue King ichakurumidza kupinza nzira dzekuongorora dzakadai muChina, kuitira kuti vanhu veChina vagone kunakidzwa nemhando yepamusoro yemwenje we LED sosi.

TM-30 inofananidza makumi mapfumbamwe nepfumbamwe emavara emhando, anomiririra akasiyana-siyana akajairika mavara anogona kuonekwa muhupenyu (kubva kune yakazara kusvika kune isina unsaturated, kubva kuchiedza kusvika kune rima)

TM-30 colorimetric chati

b.Kutsvaga chete kwechiedza chemhando yemwenje ye LED kunogona kuunza nyaradzo kune vashandisi.

Zvigadzirwa zvemhando yepamusoro zvemwenje zve LED nekuda kwekutarisisa hutano, kuratidzwa kwepamusoro, mhedzisiro yekuvhenekesa kwechokwadi, kuti zvigadzirwa zvisarudze tembiricha yeruvara, uye mwenje kuve ne-anti-glare zvinodiwa, kutonga njodzi yekufashukira kwechiedza chebhuruu, ine hungwaru masisitimu. yekudzora mwenje, kusangana nevapfumi uye vakasiyana vakangwara kudzora zvinodiwa.

c.kuora kwechiedza che LED

Kusiyana nezvivheneko zvechinyakare izvo zvinowanzotadza kungoerekana zvatadza kuenderera mberi nekushanda, zvivheneko zve LED hazviwanzo kukundikana kamwe kamwe.Nenguva yekushanda ye LED, pachava nekuora kwechiedza.LM-80 bvunzo inzira uye chiratidzo chekuongorora iyo lumen yekuchengetedza chiyero che LED mwenje sosi.

Kuburikidza nemushumo weLM-80, unogona kuronga hupenyu hwe LED, muIES LM-80-08 yakajairwa Rated Lumen Maintenance Hupenyu;L70 (maawa): inoratidza kuti chiedza chinobva lumens kuora kusvika ku70% yekutanga lumens yakashandiswa nguva;L90 (maawa): inoratidza kuti iyo mwenje sosi lumens kuora kusvika 90% yekutanga lumens yakashandiswa nguva.

d.Muvara wepamusoro wekupa index

Indekisi yemavara ekupa indekisi inzira yakakosha yekuongorora maratidziro eruvara rwezvitubu zvemwenje, uye zvakare yakakosha parameter kuyera mavara emavara ezvakagadzirwa chiedza zvinyorwa, zvinoratidzwa naRa/CRI.

Ra, R9 uye R15

Indekisi yemavara eruzhinji R ndiyo avhareji yeR1 kusvika kuR8, uye indekisi yeruvara inopa CRI avhareji yeRI-R14.Isu hatitarise chete iyo general color rendering index Ra, asi zvakare teerera kune yakakosha color rendering index R9 kune yakazara tsvuku, uye yakakosha color rendering index R9-R12 yemavara matsvuku, yero, girini uye bhuruu akazara, tinotenda kuti aya zviratidzo zvinonyatsomiririra mhando yechiedza che LED, uye nokuda kwekutengesa chiedza chechiedza chechiedza, chete kana zviratidzo izvi zvine maitiro akakwirira zvinogona kuvimbisa kupa kwepamusoro kwemavara e LED.

Kazhinji, iyo yakakwirira kukosha, kuswedera kune ruvara rwechiedza chezuva, pedyo neruvara rwayo rwepakutanga chinhu chiri kuvhenekerwa.Magetsi emwenje e LED ane yakakwira color rendering index anowanzo kusarudzwa muindasitiri yekuvhenekesa.Zvigadzirwa zvinopihwa neBlue View zvinowanzotora CRI> 95 zvinoenderana nezvinodiwa nemutengi, izvo zvinonyatso kudzorera ruvara rwezvinhu mumwenje, kuitira kuti uwane zvinofadza ziso uye nekukurudzira vanhu kuda kutenga.

e.Chiedza chinopenya

Muna 1984, Illuminating Engineering Society yeNorth America yakatsanangura kupenya semanzwiro ekugumbuka, kusagadzikana kana kurasikirwa kwemaitiro ekuona mundima yekuona kunokonzerwa nekuvhenekera kwakanyanya kudarika ziso rinogona kugadzirisa.Zvinoenderana nemhedzisiro, kupenya kunogona kukamurwa kuita kusagadzikana kupenya, kupenya-kuchinjika kupenya uye funereal glare.

LED inhamba yakakura yecylindrical kana spherical package, nekuda kwebasa re convex lens, ine yakasimba inonongedza, inopenya kusimba ine akasiyana mapakeji chimiro uye kusimba kunoenderana neangular gwara: iri munzira yakajairwa yehukuru hwechiedza kusimba, kona yemharadzano nendege yakachinjika ye 90. painotsauka kubva kune yakajairika nzira yeyakasiyana θ angle, kusimba kwechiedza kunoshandukawo.maitiro eiyo point light source ye LED.Kuitira kuti iwo mwenje we LED sosi maitiro ave nekupenya kwakanyanya uye matambudziko ekupenya anoitika.Kana ichienzaniswa nemarambi e-incandescent, mwenje wefluorescent, mwenje wesodium yakanyanya-kudzvanya uye mamwe marambi echinyakare, iyo fiber optic kutungamira kwemarambi e LED yakanyanya kunyura uye inoita kuti ibudise kupenya kusingafadzi.

f.Njodzi dzechiedza cheBlue

Nekuzivikanwa kwe LED, njodzi yemwenje yebhuruu ye LED kana kupera kwechiedza chebhuruu chave dambudziko iro vanhu vese vanofanirwa kutarisana naro uye kugadzirisa, uye mune indasitiri yeruminaire hazvisi izvo.

Iyo itsva EU general luminaire standard inotaura kuti kana mwenje unosanganisira LED, simbi halide mwenje uye mamwe akakosha tungsten halogen marambi asingakwanisi kuregererwa kubva pakuongorora njodzi yeretinal anofanirwa kuongororwa maererano neIEC/EN62778:2012 blue light injury assessment applications”, uye hazvina kufanira kushandisa zvitubu zvechiedza neblue light hazard groups anopfuura RG2.

Mune ramangwana, tichaona makambani akawanda uye akawanda, kwete kungogadzira zvigadzirwa zvemwenje zve LED, uye kwete kutarisa kune imwe neimwe parameters yechigadzirwa, asi inogona kufunga nezve nzira yekuvandudza kunaka kwechiedza zvichienderana neketani yakakosha kubva pakugadzirwa kusvika kune yose. kuzadzisa zvinodiwa.Mukuita kusimudzira, kugona kugadzira mwenje, kugona kugadzirisa zvigadzirwa, pamwe nekumisikidzwa nekuvandudzwa kwekugona kupindura nekukurumidza, ndiro dambudziko rinofanirwa kutarisana nemakambani.
