Koj yeej tsis tau hnov txog tag nrho cov spectrum COB LED loj hlob lub teeb yog tias koj tau ua raws li kev txhim kho tsis ntev los no hauv kev loj hlob teeb pom kev zoo. Ib qho ntawm cov kev hloov tshiab tshaj plaws hauv kev loj hlob lub teeb tsim yog hom teeb no. Tab sis nws yog dab tsi? Dab tsi yog qhov txawv ntawm COB LEDs los ntawm cov pa LED loj hlob teeb?
Ntawm no yog tag nrho cov ntaub ntawv koj xav tau ntawm tag nrho spectrum COB LED loj hlob teeb. Peb mam li sib tham txog qhov cuam tshuam ntawm qhov kev tsim tshiab no rau LED thev naus laus zis thiab yog tias hloov mus rau nws yuav muaj txiaj ntsig zoo rau koj tus kheej vaj hauv tsev.
Tab sis ua ntej, cov hauv paus ntsiab lus.
COB LED loj hlob teeb: nws yog dab tsi?
Nto mounted diode LEDs tau yog cov txheej txheem txheej txheem rau LED loj hlob teeb kom txog rau thaum tsis ntev los no. Cov txheej txheem no, tseem hu ua SMD, siv tus kheej ib leeg diodes affixed rau ntawm qhov chaw. Txawm hais tias tau nyob ze rau ib leeg, lawv ib txwm ua haujlwm raws li ntau qhov chaw teeb pom kev ywj pheej.
COB thev naus laus zis, uas sawv cev rau "chip-on-board," txhawb kom muaj kev sib npaug ntawm lub teeb, tsim lub teeb pom kev zoo, thiab txo cov nuj nqis. Txhawm rau tsim COB LEDs, ntau lub LEDs me me yog lub cev mounted nyob ze rau ntawm lub substrate. Ua ke, cov diodes me me no tsim ib qho qauv, ib lub teeb pom kev zoo uas ua haujlwm zoo li ib qho loj LED nti. Tsis zoo li SMD LEDs, uas ib txwm tawm lub teeb ntawm lub kaum ntse ntse, COB LEDs tawm lub teeb nyob hauv txhua qhov kev qhia (180 degrees).
COB LEDs pib raws li tag nrho cov xiav LED diodes, nyob rau hauv sib piv rau SMD LEDs, uas muaj ib tug tshwj xeeb spectrum nyob rau hauv txhua lub diode. Tom qab ntawd cov xiav LEDs yog them nrog xim daj-xim phosphor txheej. Tsis muaj qhov zoo li lub LED dawb; Tag nrho cov ntawm lawv pib lub neej li xiav LEDs thiab tom qab ntawd coated nrog phosphor los tsim lub teeb dawb, ntau npaum li fluorescent teeb, uas zoo sib xws siv phosphor los tsim lub teeb dawb.
Los ntawm kev hloov cov phosphor sib xyaw, nws tuaj yeem hloov kho xim kub ntawm lub teeb. Yog li ntawd, nws muaj peev xwm hloov lub spectrum rau veg los yog tawg ntxiv nyob rau hauv cov kev taw qhia ntawm liab los yog xiav spectrum, tab sis qhov no yuav yog ib tug teeb spectrum uas tsis hloov. Tsis tas li ntawd, muaj kev txwv nyob deb npaum li cas koj tuaj yeem hloov xiav lossis liab phosphor. Lub SolarSystem series los ntawm California Lightworks yog ib qho piv txwv ntawm qhov chaw mount LED fixture uas tso cai rau hloov lub teeb pom kev zoo hauv ib qho kev sib tw, muab qhov zoo tshaj plaws ntawm ntau qhov teeb pom kev zoo.
LED Loj hlob Lub Teeb COB
Dab tsi yog COB LEDs qhov zoo dua SMD LEDs?
Tom qab koj nkag siab txog dab tsi COB LEDs yog, koj yuav xav tsis thoob vim li cas cov tshuab no tseem muaj. Dab tsi zoo li COB thev naus laus zis muab tshaj SMD LEDs?
Kev nce hauv tsom teeb lub zog yog ib qho txiaj ntsig tseem ceeb. Txawm hais tias qhov tseeb tias SMD LED loj hlob teeb yog twb muaj txiaj ntsig ntau dua li lawv qhov sib npaug HID, nws yuav nyuaj kom haum ntau lub teeb rau hauv thaj chaw me me. Nyob rau theem zog ntau dua, LED boards yuav tsum loj dua. Kev txhim kho ntawm chip-on-board thev naus laus zis tau ua kom muaj zog ceev ntxiv ntxiv. Ntau cov chips tuaj yeem siv los ntawm ib tus neeg tsav tsheb ua tsaug rau COB architecture. Ntau lub teeb yog tsim ib square inch raws li qhov tshwm sim. Tsawg tshav kub kuj yog tsim los ntawm COB LEDs. Hauv cov teeb dej nyab thiab teeb pom kev zoo, qhov twg SMD LEDs yuav tsis haum rau hauv cheeb tsam compact ntawm ntau zog, COB LEDs tau pom tias ua tau zoo heev.
Thaum ntau diodes yog nyem rau hauv ib thaj chaw me me, lub teeb ntom ntom nce tau pom. Ntxiv mus, txij li tag nrho cov diodes no ua hauj lwm ua ke ua ib tug loj LED nti, lub teeb lawv tsim yog ntau khaus thiab mus tob rau hauv lub canopy. Ntxiv mus, COB thev naus laus zis muaj CRI siab dua, uas txhais tau hais tias thaum ib yam khoom tau teeb pom kev los ntawm COB LED loj hlob lub teeb, tib neeg lub qhov muag yuav pom nws cov xim tiag tiag. Cov neeg cog qoob loo tuaj yeem pom pom qhov tsis zoo uas yuav yog qhov qhia txog kev tawm tsam ntawm cov kab mob fungal, hlawv lub teeb, lossis lwm yam kev puas tsuaj rau cov nroj tsuag kev noj qab haus huv yam tsis muaj lub paj liab qab cuam tshuam nrog SMD LED teeb.
Txawm li cas los xij, qhov purity ntawm lub teeb spectrum yog kab tias ib qho ntawm qhov zoo tshaj plaws ntawm COB LED technology.
A Broad Spectrum COB LED Loj hlob Lub Teeb Qhov Zoo
Zoo tsim tag nrho spectrum COB LED loj hlob teeb muab tag nrho cov ntau yam ntawm pom lub teeb uas cov nroj tsuag yuav tsum tau nqa tawm lawv cov roj ntsha functions. Thaum lub sij hawm kev loj hlob, koj cov nroj tsuag xav tau ntau yam ntawm lub teeb wavelengths txij li txhua cov xim spectrum qhia cov nroj tsuag kom ua tiav cov haujlwm sib txawv txuas nrog kev loj hlob thiab kev loj hlob. Lub teeb xiav txhawb kev tsim ntawm cov hauv paus hniav thiab cov qauv stocky. Lub teeb liab nce siab blooming yields thiab yooj yim budding.
Txawm lub teeb ntsuab muaj nuj nqi. Chlorophyll qhia txog lub teeb ntsuab, ua kom nws mus deb dua rau hauv cov canopy raws li nws thaws tawm sab saum toj ntawm ib nplooj thiab mus rau hauv qab ntawm lwm tus, thaum cov nroj tsuag tsuas yog nqus tau me ntsis ntawm lub teeb ntsuab rau photosynthesis.
tag nrho spectrum Nrog lub teeb pom kev zoo, COB LED loj hlob teeb yog tsim kom haum rau koj cov qoob loo qhov kev xav tau. Tsis muaj qhov tseem ceeb wavelength raug tso tseg, thiab tsis muaj xim spectrum ua haujlwm ntau dhau.
Lub ntsiab drawback ntawm COB LEDs yog lawv qhov spectrum tas li. Kev sib xyaw spectrum tsis tuaj yeem hloov pauv, sib piv rau cov qauv SMD LEDs. Lub COB LED lub spectrum yog tsim los ntawm kev sib txuas tshwj xeeb sib xyaw ntawm phosphor uas yog siv los ua txheej rau COB LED. Cov phosphor sib xyaw ces tsim teeb. Los ntawm kev hloov cov phosphor sib xyaw, cov spectrum yuav hloov pauv me ntsis, tab sis qhov no yuav raug kho rau qhov spectrum. Cov pa hluav taws xob SMD LEDs tuaj yeem ua ke los tsim ib qho spectrum thiab hloov pauv los ntawm kev txhawb nqa lossis txo qis kev siv ntawm ntau yam xim.
