LED teeb qhov hluav taws xob ntau, kev nyab xeeb thiab kev saib xyuas tsis raug
Qhov hluav taws xob ntau ntawm cov raj LED yog qhov dav, thiab kev tiv thaiv kev tiv thaiv tau txais, yog li kev nyab xeeb ntawm cov raj LED tau lees paub. Txawm hais tias muaj qhov txawv txav, nws nyob hauv lub sijhawm lav. Peb, Langte Teeb Pom Kev, yog lub luag haujlwm rau kev saib xyuas ntawm LED raj tsis ua haujlwm. Thov so kom paub tseeb
1. LED raj voltage ntau
Dab tsi yog qhov input voltage ntawm LED raj?
Raws li cov neeg siv khoom xav tau, peb Benwe teeb pom kev zoo coj lub raj muaj ntau yam kev tawm tswv yim
1) Cov khoom siv hluav taws xob qis qis coj raj, 12v, 24v, 36v, txhua tus yog qhov muaj kev nyab xeeb. Yuav tsis ua teeb meem hluav taws xob poob. Cov raj coj muaj kev nyab xeeb siab.
2) Qhov nruab nrab nruab nrab qhov hluav taws xob coj raj. Feem ntau suav nrog, ib qho hluav taws xob 220vLED raj, ib qho hluav taws xob 110vled raj; nqaim hluav taws xob coj raj 175-265v; dav voltage coj raj 85-265v; AC thiab DC dual lub hom phiaj coj raj
3) High voltage coj raj 277v, 277v-347v-380v coj raj
Raws li rau cheeb tsam twg thiab lub tebchaws twg cov raj LED ntawm cov ntsuas hluav taws xob no haum rau, koj yuav tsum tau xa mus rau cov kev paub txuas nrog. Cov lus sib piv ntawm ib theem AC qhov ntsuas hluav taws xob muaj txiaj ntsig hauv ntau lub tebchaws hauv ntiaj teb
Piv txwv li, ntau lub tebchaws siv 220v, North America thiab Nyij Pooj siv 110v, thiab North America tseem siv 277v thiab 347v.
Nws yuav tsum nkag siab thaum tsim khoom, txwv tsis pub qhov hluav taws xob yuav tsis sib xws, cov raj coj los yuav tsis ua haujlwm, thiab tseem yuav raug hlawv.
LED raj tso zis qhov hluav taws xob
Qhov tso zis hluav taws xob tseem ceeb heev. Thaum lub zog hluav taws xob ua hluav taws xob hloov pauv, nws yuav tsum tso tawm DC qhov hluav taws xob thiab qhov tam sim no nyob rau hauv qhov tsim qauv txhawm rau txhawb nqa LED teeb vaj huam sib luag kom tso tawm lub teeb.
Cov teeb pom kev zoo LED teeb pom kev zoo tso tawm qhov hluav taws xob yog
1) Rau cov khoom siv hluav taws xob cais; feem ntau tso tawm 36-42v
2) Rau cov khoom siv hluav taws xob tsis sib cais: tso tawm dav 75-85v
LED teeb lub rooj tsav xwm voltage
Muaj ntau ntau cov teeb ci LED ntawm cov coj teeb pom kev zoo. Raws li kev xav tau tsim, sib txawv series thiab cov txheej txheem sib luag tau siv los tsim txoj hlua teeb uas ua tau raws li qhov xav tau. Nws tuaj yeem ua haujlwm tsuas yog thaum nws sib phim qhov hluav taws xob tso tawm.
1) Cov khoom siv hluav taws xob tsis sib cais, siv 20 series 60v63v, 21 series, 24 series 72v
2) Kev rho tawm lub hwj chim teeb lub rooj tsavxwm, siv 10 txoj hlua ntawm 30v, 12 hlua ntawm 36v
2. kev nyab xeeb ntawm cov raj LED
1 ib. LED raj qauv hom
Muab faib ua ib leeg-xaus lub zog LED raj thiab ob-xaus lub zog LED raj
Txhawm rau hloov cov raj siv tshuaj fluorescent nrog cov raj LED, nws yog qhov yuav tsum tau hloov kho thiab hloov pauv qhov kev cuam tshuam hauv Circuit Court hauv kab zauv. Txawm hais tias nws yog ob-qhov kawg LED raj lossis ib leeg-raj LED raj, cov thaiv xav tau hloov kho thaum txhim kho.
2 ib. LED txoj hlua thaiv txoj kev
1) Qhov ua tsis tau ntawm kev ua kom muaj zog ob npaug. Qee qhov ob-xaus LED raj muaj hluav taws xob txuas sab hauv nruab nrab ntawm ob qho kawg. Thaum ib qho kawg ntawm ob-qhov kawg LED raj tau ntxig rau hauv lub teeb teeb, lwm qhov kawg ntab yuav raug them. Hauv cov ntawv thov ua haujlwm, vim tias tus neeg siv teeb tsa feem ntau tsis tuaj yeem qhia seb lub teeb hloov tau txiav tawm lub zog hluav taws xob, thaum ib qho kawg ntawm ob-qhov kawg LED raj tau tso rau lwm qhov kawg ntawm tus pin nyob, tus neeg teeb tsa yuav poob siab los ntawm hluav taws xob poob siab. thiab raug mob ntxiv rau tib neeg lub cev los ntawm kev ntog.
2) Qhov zoo ntawm ib leeg-lub zog ua kom lub raj muaj zog, piv rau ob-qhov kawg LED raj, ib leeg-xaus LED raj muaj kev nyab xeeb. Ob qho Philips Teeb Pom Kev thiab Langte Teeb pom kev zoo tsim hluav taws xob ib leeg-hauv cov raj LED, nrog rau ob lub zog-hauv cov raj LED. Txoj kev pheej hmoo ntawm hluav taws xob poob thaum lub sijhawm teeb tsa ob-lub zog-rau LED raj yog siab dua.
3) Kev kho rau ob-qhov xaus lub zog coj lub raj, ob txoj hlua txuas nrog cov phiaj xwm hloov pauv ntxiv. Tej zaum yuav muaj hluav taws xob poob thaum lub qhov hluav taws xob tau qhib, thiab tsis muaj hluav taws xob yuav tshwm sim thaum lub qhov hluav taws xob raug kaw. Ib qho ntxiv, yog tias qhov pib hloov pauv tsis tau teeb tsa rau lub xeev kaw thaum teeb tau teeb tsa, lub teeb LED tsis tuaj yeem tso tawm.
3. LED teeb tsis ua hauj lwm txoj kev kho
1) Qhov tshwm sim tsis ua tiav: Txhua LEDs nyem.
Teeb meem: LED teeb-emitting module tsis ua hauj lwm, kev sib cuag tsis zoo.
Kev tu tsis raug: rov kho dua thiab txuas qhov ntu uas xoob.
2) Phenomenon: Txhua lub teeb LED hlaws tau tawm.
Lus Nug: Qhov hloov pauv hluav taws xob tsis muaj qhov hluav taws xob tso tawm, thiab seb qhov hluav taws xob tso tawm ntawm qhov hloov pauv hluav taws xob yog qhov tseeb.
Teeb meem kho: Kuaj lub zog thiab txuas nws mus rau qhov kawg ntawm kev hloov lub zog hloov pauv, thiab seb tus ncej zoo thiab tsis zoo ntawm lub hwj huam qaum puas raug.
3) Qhov tshwm sim tsis ua tiav: Lub teeb LED tsaus.
Teeb meem: LED polarity tau thim rov qab. Lossis LED nti ntev dhau, lossis hloov pauv lub zog hluav taws xob thiab daim ntawv lo hluav taws xob LED tsis sib xws.
Kev daws teeb meem: Xyuas kom muaj cov kab hluav taws xob zoo ntawm cov ncej zoo thiab tsis zoo, txo qhov kev sib txuas ntawm LED, thiab xyuas kom meej tias lub zog hluav taws xob thiab daim ntawv lo hluav taws xob LED zoo ib yam.
4) Teeb meem tshwm sim: Lub teeb LED ntawm qee lub voj voog tsis pom kev.
Lus Nug: Puas yog qhov kev taw qhia txuas ib txwm muaj? Puas yog lub hwj huam qaum txuas nrog? Lub hwj huam qaum tau ntsaws rov qab.
Kev daws teeb meem: Tshem tawm cov hlaws teeb coj thiab rov coj lawv mus rau qhov raug. Nco ntsoov tias cov hlau liab txuas nrog tus ncej zoo thiab cov xaim dub txuas nrog rau tus ncej tsis zoo. Txheeb xyuas qhov txuas txuas rov qab thiab txuas nws kom raug.
4. teeb meem xav tau kev saib xyuas:
Lub teeb coj yuav tsum tau tsav los ntawm qhov tam sim no tsis tu ncua. Kev siv hluav taws xob hluav taws xob ntawm ib tus ntsaum yog nruab nrab ntawm 2.8v thiab 3v, thiab tus nqi no yuav txo qis tom qab qhov kub nce ntxiv rau lub sijhawm. Lub teeb tag nrho yog tsim los ntawm ntau cov wicks hauv kab thiab sib luag, vim tias cov lej sib txawv. Yog li ntawd, qhov hluav taws xob kuj txawv. Thaum ua haujlwm, qhov tam sim no zoo ib yam, thiab qhov hluav taws xob yuav hloov nrog txoj hlua teeb.
