Dab tsi yog qhov zoo ntawm LED teeb
Muaj ntau daim ntawv thov rau LED teeb, thiab lawv kuj tseem siv tau. Dab tsi yog cov yam ntxwv ntawm LED teeb?
Koj tuaj yeem ua raws li tus sau ntawm Hanyin kom paub txog cov yam ntxwv ntawm LED teeb
1. Lub teeb lub cev me me heev
Lub teeb LED yog me me, thiab cov nti zoo heev yog ntim rau hauv pob tshab epoxy resin, yog li nws yog qhov me me, lub teeb heev, thiab tuaj yeem txuag tau ntau cov ntaub ntawv thiab qhov chaw hauv kev tsim khoom thiab kev siv.
2. Kev siv hluav taws xob tsawg
Lub zog siv hluav taws xob ntawm LED yog ntau dua 90 feem pua tsawg dua li ntawm cov teeb pom kev zoo tib yam, thiab ntau dua 70 feem pua tsawg dua li cov teeb txuag hluav taws xob. Yog li ntawd, tsuas yog LED tuaj yeem hais tau tias yog lub zog txuag hluav taws xob tiag tiag.
3. Muaj zog thiab ruaj khov
LED nti yog tag nrho encapsulated nyob rau hauv epoxy resin. Cov me me epoxy resin hais yog qhov nyuaj heev kom tawg, thiab tag nrho lub teeb lub cev tsis muaj qhov xoob;
Cov nti sab hauv yog qhov nyuaj heev rau kev tawg, thiab muaj cov nyhuv thermal me me thiab tuaj yeem hloov pauv thiab fuse. Cov yam ntxwv no ua rau LEDs nyuaj rau kev puas tsuaj. Piv nrog rau cov teeb pom kev zoo tib yam, cov teeb fluorescent, LEDs muaj zog heev.
4. Lub neej ua haujlwm ntev
Raws li qhov tsim nyog tam sim no thiab qhov hluav taws xob, qhov kev pab cuam lub neej ntawm LED tuaj yeem ncav cuag 100, 000 teev, uas yog, cov khoom siv theoretical lub neej tuaj yeem ncav cuag ntau tshaj 10 xyoo, thiab lub hnub qub ua haujlwm ntev hauv thaj chaw teeb thiab teeb.
Rau qee lub sijhawm uas xav tau lub teeb pom kev ntev, xws li lub khw ntxuav tsheb lossis chaw nres tsheb,chaw nres tsheb LED teebyog thawj qhov kev xaiv.
5. Muaj kev nyab xeeb tsawg voltage
LED siv lub tshuab hluav taws xob qis DC (uas tuaj yeem kho qhov hloov pauv mus rau qhov tam sim no ncaj qha), thiab lub zog hluav taws xob yog nyob nruab nrab ntawm 6 ~ 24V, uas txawv ntawm cov khoom mus rau cov khoom.
Hauv luv luv, nws siv DC fais fab mov uas muaj kev nyab xeeb dua li cov khoom siv hluav taws xob siab thiab tshwj xeeb tshaj yog haum rau cov tsev thiab cov chaw pej xeem.
6. Kev siv ntau yam
Vim nws qhov me me, txhua chav LED nti yog square lossis lub voj voog ntawm 3 ~ 5 hli, yog li nws tsim nyog rau kev npaj cov khoom siv nrog cov txheej txheem ua qauv. Piv txwv li, nyob rau hauv kev tsim cov mos mos, khoov lub teeb, strips, thiab tshwj xeeb zoo li lub teeb, tam sim no, tsuas yog LEDs yog tsim nyog.
7. Cov xim nplua nuj
Yav dhau los, cov xim ntawm lub teeb yog ib leeg heev. Txhawm rau ua tiav lub hom phiaj ntawm cov xim, pleev xim rau saum npoo ntawm lub teeb lossis npog lawv nrog cov xim dawb; los yog sau cov teeb nrog inert roj kom emit lub teeb, yog li cov nplua nuj ntawm cov xim yog txwv.
LED yog digitally tswj, thiab lub teeb-emitting nti tuaj yeem tawm ntau yam xim tam sim no, suav nrog liab, ntsuab, thiab xiav peb xim thawj. Nrog rau peb cov xim thawj, los ntawm kev tswj hwm, lub ntiaj teb muaj yeeb yuj tuaj yeem rov qab los.
8. Tsawg cua sov dissipation
LED yog lub teeb txias txias dua. Nws tsis radiate ntau infrared thiab ultraviolet rays xws li incandescent teeb thiab fluorescent teeb.
Nws yog tshwj xeeb tshaj yog haum rau lub teeb pom kev zoo uas yuav tsum tau tso saib cov ntsiab lus zoo ntawm cov khoom. Xws li tsheb nthuav dav teeb rau kev ntxuav tsheb. Yuav luag tsis muaj qhov cuam tshuam cua sov tam sim no zoo li lub teeb incandescent, thiab nws yuav tsis cuam tshuam los ntawm thermal expansion thiab txias contraction.
Nws yuav tsis ua rau lub teeb daj, yuav tsis ua kom lub hnub nyoog ntawm lub teeb, thiab yuav tsis ua rau lub tsev xog paj cuam tshuam rau ib puag ncig ib puag ncig.
9. Tsawg ib puag ncig muaj kuab paug
Kev tiv thaiv ntawm LED ntawm ib puag ncig yog tshwm sim hauv peb yam:
Ua ntej, tsis muaj kev phom sij ntawm cov hlau mercury. Tsis zoo li cov teeb fluorescent, uas tsis siv cov mercury uas muaj kev phom sij loj hauv LED teeb, yuav tsis muaj kev phom sij rau pej xeem xws li mercury ions thiab phosphors uas yuav xau thaum lub sijhawm tsim khoom ntawm lub teeb lossis tom qab nws puas lawm.
Qhov thib ob, epoxy resin siv los ua LEDs yog cov organic polymer compound, uas muaj lub cev zoo thiab tshuaj lom neeg tom qab kho. Nws muaj kev sib raug zoo siab rau wafers thiab hlau, yog ib qho nyuaj thiab hloov tau, ruaj khov rau saline, alkali, thiab cov kuab tshuaj feem ntau, thiab tsis yooj yim rau kev puas tsuaj. Txawm tias puas los yog muaj hnub nyoog, nws tuaj yeem rov ua dua thiab rov siv dua yam tsis ua rau muaj kuab paug rau ib puag ncig.
Thib peb, vim yog cov teeb pom kev zoo ntawm LED teeb thiab cov ntxaij vab tshaus, lub teeb tsim tawm feem ntau tawg, thiab lub teeb paug tsis tshua muaj tshwm sim.
10. Kev txuag nqi ntau dua
Piv nrog rau cov teeb pom kev zoo, thiab cov teeb fluorescent, cov nqi yuav ntawm LED teeb yog siab dua - qee qhov. Txawm li cas los xij, kev siv hluav taws xob ntawm LED yog qhov tshwj xeeb tsawg, uas tuaj yeem txuag tau ntau ntawm cov nqi hluav taws xob hauv lub sijhawm ntev, thiab tuaj yeem txuag cov peev hauv kev hloov cov teeb, yog li kev siv cov nqi siv tau zoo dua.
