Puas yog COB lub teeb ci dua li LED?
Jun 06, 2023
I. Kev Taw Qhia
COB thiab LED teeb yog ob qho tib si kev xaiv teeb pom kev zoo, tab sis feem ntau tsis meej pem nyob ib puag ncig lawv qhov ci ci thiab qhov twg yog qhov zoo dua. Hauv tsab xov xwm no, peb yuav tshuaj xyuas qhov sib txawv ntawm COB thiab LED teeb thiab txiav txim siab seb puas los yog tsisCOB teebyeej ci duaLED teeb.
II. COB teeb yog dab tsi?
1: Lub ntsiab lus ntawm COB teeb
COB stands rau "chip on board" thiab hais txog ib hom ntawm LED technology nyob rau hauv uas ntau microchips yog mounted rau ib tug substrate. Txoj kev tsim kho no tso cai rau kev tso denser ntawm diodes, uas tsim kom muaj lub teeb pom kev zoo dua thiab hnyav dua.
2: COB lub teeb ua haujlwm li cas?
COB lub teeb ua haujlwm los ntawm kev sib txuas cov teeb pom kev zoo ntawm ntau lub teeb ci LED mus rau ib lub rooj tsav xwm ib leeg. Vim hais tias cov diodes nyob ze ua ke thiab emit lub teeb los ntawm ib qho chaw me me, lub teeb uas ua tau ntau dua thiab tsom. Qhov no ua rau COB teeb pom kev zoo rau cov ntawv thov uas xav tau kev ci ntsa iab, xws li tsheb teeb pom kev zoo, teeb pom kev hauv chaw ntau pob, thiab teeb pom kev lag luam.
3: Qhov zoo ntawm COB teeb
High brightness: COB teeb muaj peev xwm tsim lub teeb ci ntsa iab vim lawv cov chips LED ntom ntom.
Compact me me: Vim tias lawv tsim, COB teeb tuaj yeem ua kom me me dua li cov teeb pom kev zoo ib txwm muaj thaum tseem tuav lub teeb ci siab.
Zog-npaum: COB teeb muaj lub zog-npaum thiab tuaj yeem tsim ntau lub teeb ib watt dua li lwm yam teeb pom kev zoo.
Ntev lifespan: COB teeb muaj lub neej ntev dua li cov kev xaiv teeb pom kev zoo, uas tuaj yeem txuag nyiaj ntawm kev hloov thiab tu cov nqi dhau sijhawm.
III. LED teeb yog dab tsi?
1: Lub ntsiab lus ntawm LED teeb
LED stands rau "lub teeb emitting diode," uas yog ib tug semiconductor ntaus ntawv uas emits lub teeb thaum ib tug hluav taws xob tam sim no ntws los ntawm nws. LED teeb pom kev zoo tau dhau los ua neeg nyiam nyob rau xyoo tas los no vim nws lub zog ua haujlwm siab, lub neej ntev, thiab ntau yam.
2: LED teeb ua haujlwm li cas?
LED teeb ua hauj lwm los ntawm kev hla ib qho tam sim no los ntawm cov khoom siv semiconductor, xws li silicon, uas ua rau cov hluav taws xob tso tawm lub zog hauv daim ntawv ntawm photons (lub teeb). Tsis zoo li cov teeb pom kev zoo ib txwm muaj, uas tsim lub teeb los ntawm cua sov lub teeb, LED teeb tsis muaj filament thiab yog li tsis tsim hluav taws xob raws li cov khoom tsim tawm. Qhov no ua rau LED teeb muaj txiaj ntsig zoo dua li lwm yam khoom siv hluav taws xob.
3: Qhov zoo ntawm LED teeb
Zog txuag hluav taws xob: LED teeb muaj lub zog txuag hluav taws xob thiab tuaj yeem haus txog li 80 feem pua tsawg zog dua li cov qhov muag teev.
Lub neej ntev: LED teeb muaj lub neej ntev dua li kev xaiv teeb pom kev zoo, feem ntau kav ntev txog 50,000 teev lossis ntau dua.
Ib puag ncig tus phooj ywg: LED teeb tsis muaj tshuaj lom neeg xws li mercury, uas tuaj yeem tsim kev puas tsuaj rau tib neeg thiab ib puag ncig.
Ntau yam: LED teeb tuaj ntau yam duab, qhov ntau thiab tsawg, xim, thiab kev siv zog, ua rau lawv zoo tagnrho rau ntau yam kev siv, los ntawm cov teeb pom kev zoo sab hauv mus rau sab nraum zoov kos npe.
IV. Kev sib piv ntawm COB thiab LED teeb
1: Brightness
COB teeb feem ntau suav hais tias yog qhov ci dua li cov teeb pom kev zoo ib txwm muaj vim tias lawv tuaj yeem tsim lub teeb pom kev zoo dua, hnyav dua. Txawm li cas los xij, tag nrho qhov ci ci ntawm lub teeb ci yog nyob ntawm tus naj npawb ntawm diodes siv thiab tus nqi ntawm lub zog siv rau lawv. Qee qhov xwm txheej, LED teeb tuaj yeem ci li COB teeb.
2: Zog efficiency
Ob lub COB thiab LED teeb muaj lub zog-npaum, tab sis COB teeb feem ntau ua tau zoo dua li cov teeb pom kev zoo ib txwm muaj vim tias lawv tuaj yeem tsim ntau lumens ib watt. Txawm li cas los xij, qhov kev siv hluav taws xob tiag tiag ntawm lub teeb pom kev zoo nyob ntawm ntau yam xws li nws cov qauv tsim, hom diode siv, thiab qhov zoo ntawm cov neeg tsav tsheb Circuit Court.
3: Nqi
Tus nqi ntawm COB teeb yog feem ntau siab dua li cov teeb pom kev zoo ntawm LED teeb vim qhov nyuaj ntawm lawv cov kev tsim kho thiab cov ntaub ntawv siv. Txawm li cas los xij, tus nqi rau ob hom teeb tuaj yeem sib txawv nyob ntawm qhov zoo, hom, thiab daim ntawv thov.
4: Durability
COB teeb yuav ua tau ntev dua li cov teeb ci LED ib txwm muaj vim tias lawv tsis tshua muaj kev puas tsuaj los ntawm tshav kub thiab ya raws. Tsis tas li ntawd, vim hais tias COB teeb muaj lub teeb pom kev zoo dua thiab raug ntsia ncaj qha mus rau lub substrate, lawv yuav tsis tshua muaj kev poob vim yog ib tus neeg LED nti burnout lossis tsis ua haujlwm. Txawm li cas los xij, LED teeb muaj lub neej ntev dua li COB teeb thiab yuav kav ntev txog 50, 000 teev lossis ntau dua yam tsis tas yuav hloov pauv.
V. Xaus
Hauv cov ntsiab lus, COB stands rau "chip on board" thiab hais txog ib yam ntawm LED thev naus laus zis uas tso cai rau ntau lub microchips tau nruab rau ntawm ib qho substrate, uas ua rau muaj qhov tso tawm ntawm diodes denser thiab ntau lub teeb pom kev zoo. LED stands rau "lub teeb emitting diode," uas yog ib tug semiconductor ntaus ntawv uas emits lub teeb thaum ib tug hluav taws xob tam sim no hla nws. LEDs muaj lub zog txuag, muaj lub neej ntev, thiab tuaj nyob rau hauv ntau yam duab, qhov ntau thiab tsawg, xim, thiab kev siv zog.
Thaum sib piv COB thiab LED teeb, COB teeb zoo li yuav ci dua thiab siv zog ntau dua li cov teeb ci LED ib txwm muaj tab sis feem ntau kim dua thiab yuav tsis kav ntev. Ntawm qhov tod tes, LEDs muaj ntau yam zoo, ib puag ncig tus phooj ywg, thiab yuav kav ntev txog 50, 000 teev lossis ntau dua.
Raws li cov kev xav tau tshwj xeeb, nws tau pom zoo kom siv COB teeb rau cov ntawv thov uas xav tau kev ci ntsa iab thiab siv zog, xws li tsheb teeb pom kev zoo, teeb pom kev hauv chaw ntau pob, thiab teeb pom kev lag luam. LED teeb yog zoo tagnrho rau ntau yam kev siv, los ntawm lub teeb pom kev zoo sab hauv mus rau sab nraum zoov signage, qhov twg versatility, zog efficiency, thiab ib puag ncig tus phooj ywg yog ib yam tseem ceeb.
