Cov teeb meem dab tsi yuav tsum tau them rau thaum LED siv hauv chav kawm teeb pom kev zoo?
Raws li lub xeev cov khoom siv hluav taws xob semiconductor lub teeb, LED teeb hlaws tau txuas ntxiv txhim kho lub teeb pom kev zoo nyob rau xyoo tas los no, thiab lawv cov nqi tau poob qis. Piv nrog rau cov teeb pom kev zoo ib txwm muaj, LED teeb hlaws muaj ntau yam zoo xws li qhov me me, hloov tau thiab tswj tau, lub neej ntev, thiab lwm yam. LED teeb hlaws tau txais kev loj hlob sai thiab nthuav dav hauv ntau daim ntawv thov xws li chav kawm teeb pom kev zoo. Tam sim no, pej xeem lub tswv yim muaj ntau yam kev txhawj xeeb txog lub teeb xiav, tab sis peb tsis tuaj yeem pom qhov muag tsis pom nws.
1. Lub teeb xiav yog ib qho tseem ceeb ntawm lub teeb dawb, uas tsis tsuas yog ua lub luag haujlwm tseem ceeb hauv kev ua kom cov xim rendering, tab sis kuj tswj cov circadian atherosclerosis. Lub hnub ci sab nraum zoov tuaj yeem ua tau raws li kev ua haujlwm ntawm kev sib koom ua ke ntawm tib neeg lub cev' lub circadian atherosclerosis (los yog lub moos lom neeg), thiab lub teeb xiav uas tau txais sab hauv tsev yog tsawg dua qhov koob tshuaj tau txais los ntawm kev ua si sab nraum zoov. Lub teeb xiav thiab lub teeb txias dawb tuaj yeem siv los tsim lub teeb pom kev zoo los pab tib neeg kom tau txais cov koob tshuaj xiav xiav txhua hnub kom ntseeg tau tias lawv cov circadian rhythms nyob rau hauv kev sib raug zoo nrog lawv cov circadian rhythms.
Ntawm qhov tod tes, lub" xiav teeb phom sij" peb feem ntau hnov hais txog qhov tseeb tias yog lub teeb ci ci ntawm 400-500nm xiav lub teeb band ntawm lub teeb ci siab dhau lawm, qhov muag yuav ua rau photochemical puas rau lub retina tom qab saib ncaj qha ntawm lub teeb rau lub sijhawm ntev. Qhov teeb meem xiav lub teeb yog qhov tseem ceeb ntawm kev sib xyaw ua ke ntawm radiance, xiav lub teeb hnyav ua haujlwm thiab lub sijhawm. Los ntawm qhov pom ntawm spectral, qhov feem ntawm lub teeb xiav nyob rau hauv lub spectrum ntawm LED teeb hlaws dai nce thaum xim kub nce, tab sis tsis muaj dab tsi tshwj xeeb piv nrog lub teeb xiav nyob rau hauv spectrum ntawm fluorescent teeb. , Thaum cov xim kub zoo ib yam, qhov txwv sab sauv ntawm lub teeb xiav kev nyab xeeb ntawm lub teeb ci LED hlaws zoo ib yam li lub teeb fluorescent.
Muaj kev sib koom ua ke kev ntsuas tshwj xeeb GB / T20145-2006 / IEC62471 rau kev phom sij xiav lub teeb nyob hauv tsev thiab txawv teb chaws. Lub teeb LED rau lub teeb pom kev zoo txhua hnub yog nyob rau hauv chav kawm 0 lossis chav kawm 1 thiab nyob rau hauv qeb kev nyab xeeb.
Niaj hnub no, peb feem ntau tham txog qhov teeb meem ntawm" LED teeb qhov chaw tuaj yeem siv hauv chav kawm teeb pom kev zoo ntawm theem no", uas tam sim no ua rau muaj kev sib tham thiab tsis ntseeg hauv zej zog.
2. Raws li keeb kwm yav dhau los uas cov khoom siv teeb pom kev zoo tau them nyiaj ntau thiab ntau dua, thiab teeb meem xiav xiav, stroboscopic thiab lwm yam teeb meem tau dhau los ua kev sib raug zoo, puas LED teeb hlaws hlaws ua rau muaj kev phom sij rau kev pom kev noj qab haus huv ntawm cov menyuam yaus thaum lub sijhawm kev loj hlob?
Txawm hais tias nws yog LED teeb hlaws lossis cov teeb pom kev zoo ib txwm muaj, cov kev sib raug zoo yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm cov qauv teeb pom kev zoo rau ntau qhov ntsuas thaum siv rau hauv chav kawm teeb pom kev zoo.
Vim txoj kev loj hlob thiab nrov ntawm LED teeb hlaws teeb pom kev zoo cov khoom, nws yog ib qho tsim nyog yuav tsum ua qauv LED teeb hlaws rau hauv chav kawm teeb pom kev zoo. Tam sim no, Tuam Tshoj Zoo Certification Center (CQC) tau tso tawm"Technical Specification for Energy Conservation Certification of Classroom Lighting Products in Primary and Secondary Schools and Kindergartens" nyob rau hauv 2016., LED teeb hlaws cov khoom tsis tau ntxiv standardized, thiab lwm yam qauv rau LED chav kawm ntawv teeb pom kev zoo tseem tsis tau txhim kho.
Txawm hais tias muaj teeb meem kev nyab xeeb nyob rau hauv LED teeb hlaws Tam sim no, qhov ua tau zoo ntawm cov teeb pom kev zoo thiab cov teeb pom kev zoo ntawm cov teeb ci dawb LED hlaws rau cov teeb pom kev dav dav tau dhau los ntawm cov teeb pom kev zoo, thiab tuaj yeem ua tiav cov xim zoo nkauj thiab kev ruaj ntseg siab, uas tuaj yeem ua tau raws li cov kev xav tau ntawm kev txawj ntse. teeb pom kev zoo rau dimming. Tus yuam sij rau kev siv LED teeb hlaws dai nyob ntawm seb lub teeb zaum kawg tuaj yeem ua tau raws li qhov xav tau ntawm cov teeb pom kev zoo thiab cov khoom siv teeb pom kev zoo.
Hais txog kev nyab xeeb photobiological ntawm LED teeb hlaws, koj tuaj yeem xa mus rau daim ntawv dawb" General Lighting LED thiab Blue Light" sib koom ua ke los ntawm International Semiconductor Lighting Alliance, National Semiconductor Lighting Engineering R& D thiab Industry Alliance thiab Tuam Tshoj teeb pom kev zoo nyob rau lub Xya hli ntuj 2013. Daim ntawv dawb qhia meej tias kev siv cov khoom tsim nyog dawb LED teeb pom kev zoo rau kev siv dav dav. teeb pom kev zoo tag nrho rau tib neeg lub qhov muag.
Dab tsi yuav tsum tau them sai sai rau thaum siv LED teeb hlaws hauv chav kawm?
Tam sim no, kev siv lub tsev kawm ntawv teeb pom kev zoo LEDs muaj teeb meem xws li cov khoom lag luam tsis zoo, tsis sib xws, kev ua lag luam tsis zoo, tsis muaj kev saib xyuas tsis tu ncua, thiab cov qauv tsis zoo, tab sis cov teeb meem tsis tuaj yeem raug ntaus nqi rau LED teeb hlaws lawv tus kheej.
3. Cov teeb pom kev hauv chav kawm yuav tsum tau xyuam xim rau cov teeb meem hauv qab no thaum siv cov khoom siv LED:
1. Kev xaiv ntawm LED teeb hlaws yuav tsum ua kom tau raws li cov qauv kev cai ntawm lub teeb xim zoo thiab lwm yam zoo, nrog rau kev ua kom tau raws li qhov yuav tsum tau muaj kev nyab xeeb, kev ua tau zoo, kev ntseeg siab, kev tiv thaiv ib puag ncig, thiab lwm yam;
2. Lub teeb pom kev zoo thiab lub teeb pom kev zoo yuav tsum raug siv kom raug, suav nrog kev siv lub teeb pom kev zoo tsim nyog, txoj kev teeb tsa kom raug, kev tshuaj xyuas thiab tu, thiab lwm yam;
3. Txhua yam khoom siv teeb pom kev zoo thiab cov khoom siv teeb pom kev zoo yuav tsum tau kuaj xyuas kev nyab xeeb photobiological. Txawm hais tias lawv muaj kev nyab xeeb raws li tus qauv thiab tsis tas yuav muaj cov cim ceeb toom ntxiv, cov neeg siv yuav tsum tseem tsis txhob saib ncaj qha rau cov teeb pom kev zoo no ntev. Tshwj xeeb tshaj yog ntawm luv luv.
Niaj hnub no, nrog kev txhim kho sai ntawm LED teeb hlaws thev naus laus zis, LED teeb tau maj mam hloov lub ntsiab" tsis tshua muaj ntiaj teb tricolor fluorescent teeb" siv hauv chav kawm teeb pom kev zoo. Puas yog lub teb chaws tus qauv tam sim no rau chav kawm teeb pom kev zoo tso cai thiab pom zoo kom siv LED teeb hlaws?
Puas yog lub teb chaws tus qauv tso cai siv cov teeb ci LED hauv cov chav kawm? Cov qauv teeb pom kev zoo hauv chav kawm tam sim no suav nrog" Chav Kawm Teeb pom kev zoo thiab teeb pom kev zoo huv si rau cov tsev kawm ntawv theem pib thiab theem nrab" (GB7793-2010)," Tsim Specifications for Primary and Secondary Schools" (GB50099-2011)," Cov Tsev Kawm Ntawv Qib Siab thiab Qib Siab thiab Chav Kawm Qib Kindergarten" Teeb pom kev zoo tsim Specifications (DB31/539-2011), Architectural Lighting Design Standards (GB50034-2013), thiab Technical Specifications for Energy-Saving Certification of Lighting Products in Primary and Secondary Schools and Kindergarten Classrooms (CQC3155-2016) yog txhua yam ua tau zoo. qhov nruab nrab thiab teeb pom kev zoo ntawm cov chav kawm. Illumination, blackboard nruab nrab illuminance thiab illuminance uniformity, uniform glare tus nqi, xim rendering Performance index, lub teeb qhov chaw xim kub, teeb efficiency thiab lub hwj chim ceev thiab lwm yam qhia tau hais tias yuav tsum tau, cov qauv no muaj feem xyuam rau ntau yam teeb pom kev zoo.
