6 Kev Ua thiab Tsis Ua Haujlwm ntawm LED Teeb pom kev zoo Nws yog ib qho tseem ceeb kom nrhiav tau lub teeb pom kev zoo los ua kom pom koj qhov chaw ua lag luam.Txhua qhov chaw lag luam muaj nws tus kheej cov teeb pom kev zoo xav tau.Kev teeb pom kev zoo ib cheeb tsam muaj ntau yam txiaj ntsig, qhov tseem ceeb tshaj plaws ntawm cov neeg ua haujlwm kev nyab xeeb thiab kev tsim khoom.Peb ntawm Stars thiab Stripes Teeb pom kev zoo muaj ntau yam sib txawv LED coj mus muag khoom teeb pom kev zoo uas yuav pab ua kom tau raws li qhov xav tau ntawm ntau qhov chaw.Teeb pom kev zoo kuj muaj qhov cuam tshuam loj rau qhov chaw ua lag luam ua haujlwm li cas, yog li thaum nws los txog rau lub sijhawm los txiav txim siab qhov teeb pom kev zoo tshaj plaws, nws yog ib qho tseem ceeb kom paub tseeb tias koj tab tom yuav yam zoo rau koj txoj kev lag luam.Yog tias koj tsis paub meej tias lub teeb pom kev zoo tshaj plaws rau koj qhov chaw, hu rau ib tus ntawm peb cov kws paub txog teeb pom kev zoo uas yuav pab koj ua ke ib qho kev teeb tsa los txhim kho koj qhov chaw ua haujlwm teeb pom kev zoo thiab haum koj cov peev nyiaj.Peb muaj ntau txoj kev xaiv ntawm LED teeb pom kev zoo rau cov chaw lag luam, los ntawm cov slabs thiab cov bays siab, kom tawm cov paib thiab cov teeb pom kev tsis zoo, Hnub Qub thiab Kab Tsuag tau koj them.

LED teeb pom kev zoo ceev faj 1. Xim kub

Xim kub thiab lumens ib watt yuav tsis pom zoo, txawm hais tias tej zaum koj yuav paub tias koj xav tau ntawm qhov ci ntawm LED (tsawg kawg nrog lub teeb ntawm lub voj voog lossis lub teeb ci).Xim kub tsuas yog siv rau lub teeb dawb xwb: nws yog qhov ntsuas qhov txias (xiav) lossis sov (liab) lub teeb pom.Qhov no tuaj yeem dag ntxias, vim tias lub teeb xim, ntsuas hauv Kelvin (K), qhia txog cov tsos ntawm cov hlau (dub lub cev radiators) uas kub hnyiab ntawm ntau yam kub.Yog li "cooler" lossis xim xiav yog qhov sov dua.Nws feem ntau suav hais tias lub teeb sov yog 2700K txog 3500K, nruab nrab dawb yog li 4000K, thiab txias dawb yog siab dua 4700K.

LED teeb pom kev zoo ceev faj 2. Lub teeb wavelength

Lwm qhov teeb meem uas tib neeg muaj thaum xaiv LEDs yog qhov ntxoov ntxoo ntsuab lossis xiav tsis yog qhov lawv xav tau.Txhawm rau kom tau txais cov xim koj xav tau tiag tiag, koj yuav tsum tau them sai sai rau lub wavelength specification los txiav txim siab, piv txwv li, seb puas yuav tau txais ib qho tseeb ntsuab lossis chartreuse.Txhawm rau kawm paub ntau ntxiv txog LED wavelengths thiab pom qhov pom kev sawv cev ntawm txhua qhov LED wavelength hauv kev nqis tes ua.

Peb, lumens ib watt

Kev ua tau zoo yog ntsuas hauv lumens ib watt (lm / W), uas yog tag nrho lumens tawm los ntawm LED muab faib los ntawm tag nrho lub zog noj.Los ntawm cov kev paub dhau los, cov neeg siv khoom nyiam tsom 100 lm / W rau tag nrho cov kab ke.Qhov no suav nrog kev poob vim yog cua sov, lo ntsiab muag, lub teeb qhia thiab lub zog hloov pauv, yog li 140 lm / W lossis siab dua LEDs feem ntau yuav tsum tau ua.Cov neeg paub zoo hauv LED teeb pom kev zoo xws li CREE thiab Samsung muab LEDs txog li 200lm / W thiab taw qhia qhov twg qhov ntsuas tau ua tiav.Qhov siab tshaj plaws ntawm ib qho LED feem ntau ua tiav ntawm qhov qis dua tam sim no tshaj qhov ntsuas siab tshaj plaws, yog li lub teeb pom kev zoo nyob deb ntawm kev zam los ntawm kev sib tham ntawm tus nqi piv rau kev ua haujlwm zoo.

LED teeb pom kev zoo ceev faj 4. Qhov taw qhia teeb

Yog tias koj daim ntawv thov xav kom pom kev ceeb toom yooj yim (xws li lub teeb ntsais ntawm lub router), tag nrho cov txheej txheem tuaj yeem ua kom yooj yim nrog qhov taw qhia LED.Kev taw qhia LEDs tuaj yeem siv yuav luag txhua yam xim thiab tuaj yeem ntsuas qhov loj ntawm daim ntawv thov.Xub xa cov 0402 ntim LEDs rau hauv 10mm T-3 pob.Kev yuav cov teeb ci ntsa iab thiab teeb ntawm LEDs tuaj yeem txuag lub sijhawm ntawm koj tus qauv tsim tom ntej.

Tsib, wavelength visibility

Kev pom zoo nyob ntawm qhov pom lub kaum ntse ntse ntawm LED thiab peb lub qhov muag pom zoo li cas cov xim xaiv, nrog rau lub lumen tso zis ntawm diode.Piv txwv li, lub teeb ntsuab LED khiav ntawm 2 mW zoo li ci ntsa iab rau peb li liab LED khiav ntawm 20 mA.Tib neeg lub qhov muag muaj qhov zoo ntawm ntsuab rhiab heev dua li lwm cov wavelength, thiab qhov rhiab heev yog skewed ntawm infrared thiab ultraviolet ntawm ob sab ntawm lub ncov no.Txheeb xyuas qhov pom spectrum hauv qab no rau kev siv.Liab yog ib qho ntawm cov xim nyuaj dua kom ci rau tib neeg lub qhov muag vim nws nyob ze rau ntawm ntug thiab tuaj yeem hloov mus rau hauv qhov pom tsis pom lub teeb.Ironically, liab yog xim feem ntau siv los ua qhov taw qhia.

Kev ceev faj rau kev coj teeb pom kev zoo 6. Saib lub kaum sab xis piav qhia

Lub kaum sab xis saib ntawm LED yog qhov kev ncua deb ntawm qhov nruab nrab ntawm kab teeb ua ntej lub teeb poob ib nrab ntawm nws qhov kev siv.Feem ntau qhov tseem ceeb yog 45 degrees thiab 120 degrees, tab sis lub teeb kav dej lossis lwm yam kev taw qhia lub teeb uas tsom lub teeb rau hauv kab teeb yuav xav tau lub kaum sab xis ntawm 15 degrees lossis tsawg dua.Ua raws li rau qhov kev xav hauv siab, koj tus qauv LED tom ntej no yuav ua kom zoo rau kev cuam tshuam.Xav paub yog tias nws zoo dua los siv OLED zaub?Peb tab tom tsoo nws mus rau hauv LED vs OLED: cov zaub twg zoo tshaj?Yog tias koj tab tom tsim cov teeb pom kev zoo ua tiav, tshawb xyuas peb cov cuab yeej Lighting Designer, huab-raws li platform tsim los pab tsim kom tiav LED teeb pom kev zoo system daws teeb meem.
