Teeb pom kev zoo uas muab los ntawm cov chaw tsim khoom ntawm Lavxias kev lag luam muaj ntau haiv neeg. Tej zaum lawv yuav txawv ob qho tib si nyob rau hauv tsos thiab nyob rau hauv hom emitters ntsia rau hauv lawv. Txog hnub tim, cov khoom siv nrov tshaj plaws ntawm LED-cov ntsiab lus. Txawm li cas los xij, qhov teeb meem yog tias tsis yog txhua tus ntawm lawv tuaj yeem ua haujlwm yam tsis muaj khoom siv ntxiv. Niaj hnub no peb yuav tham txog cov khoom siv hluav taws xob rau LED strips. Koj yuav tsum paub seb hom khoom siv li cas pom, lawv ua haujlwm li cas thiab xaiv lawv li cas.
PSU yog dab tsi rau LED sawb
Ib qho khoom siv zoo sib xws yog siv los txo qhov hluav taws xob hluav taws xob thiab ua kom lub zog tam sim no. Qhov tseeb, LED sawb fais fab mov yog transformer nruab nrog lub rectifier thiab hnav khaub ncaws tiv thaiv, uas tuaj yeem ua tau yooj yim, tsis tiv thaiv los ntawm ya raws, lossiskaw. Ntxiv nrog rau cov ntsiab lus teev tseg, cov khoom siv hluav taws xob tau nruab nrog cov capacitors uas ua haujlwm los tiv thaiv kev ua tsis tiav thiab ua kom muaj kev cuam tshuam ntau yam. Qhov loj dua nws lub peev xwm, qhov zoo dua rau LED sawb.
Ib tus neeg siv hluav taws xob raug xaiv raws li qhov tsis raug ncaj qha hauv qab cov khoom siv LED uas twb tau yuav los yog ib txhij nrog nws yog tias muaj kev suav ua ua ntej. Ntau tus ntseeg hais tias qhov kev yuav khoom ntawm cov cuab yeej no yog qhov tsis raug cai ntawm cov nyiaj pov tseg, thiab lawv ua lub zog rau LED sawb nrog lawv tus kheej txhais tes. Nws tsis yog qhov nyuaj rau ua qhov no; lub zog muab hluav taws xob los ntawm lub khoos phis tawj qub tuaj yeem ua raws li nws. Qhov tseem ceeb tshaj plaws yog tag nrho cov yam ntxwv tsim nyog haum.
Hom khoom siv hluav taws xob los ntawm cov zis hluav taws xob
Txhim kho lub teeb pom kev ntawm cov tsev thiab cov tsev ntiag tug, 3 hom khoom siv hluav taws xob tau siv.
- 12V tso zis voltage yog cov khoom siv ntau tshaj plaws uas tuaj yeem pom yuav luag txhua qhov chaw. Yog li ntawd, nyob rau hauv qhov kev tshwm sim ntawm ib tug tsis ua hauj lwm ntawm xws li ib tug unit, nws yuav tsis yooj yim los hloov nws.
- 24 V - Txawm hais tias cov khoom siv no pom, lawv muaj tsawg dua. Vim tsis xav tau ntau heev hauv khw muag khoom, feem ntau muaj tsawg tsawg ntawm cov blocks. Yog tias koj xav yuav, tsis muaj kev lees paub tias PSU tuaj yeem pom sai sai, tshwj xeeb tshaj yog hauv cov nroog me.
- 36 B yog cov cuab yeej tshiab. Txog rau tam sim no, qhov kev thov rau cov khoom siv hluav taws xob LED no tsawg heev. Qhov no ua rau ib qho tsis ntseeg tias PSUs yuav nyob hauv khw.
Txuas txuas lub cuab yeej ruaj khov
Cov lus nug ntawm yuav ua li cas txuas LED sawb mus rau lub zog hluav taws xob yog qhov yooj yim heev, tab sis nws muaj qee qhov nuances. Cov terminals rau kev sib txuas yog qhia nyob rau hauv rooj plaub PSU - nws yuav nyuaj heev ua yuam kev ntawm no. Tab sis nyob rau hauv qhov ntev ntawm bands thiab txoj kev ntawm kev hloov, muaj ntau ntau tsis meej pem.
LED sawb uas muaj zog yuav tsum tsis pub ntev tshaj 5 m. Txwv tsis pub, txoj kev coj mus yuav tsis tuaj yeem tiv taus lub nra thiab hlawv. Yog tias koj xav tau txuas lub strip ntev, koj tuaj yeem ntxiv ntu thib ob. Tab sis kev sib txuas yuav tsum tau ua nyob rau hauv parallel. Nrog rau ib ntus, nws yuav tig tawm zoo ib yam li kev teeb tsa tag nrho ntu ntawm 10 m, thiab qhov no tsis tuaj yeem lees txais.
Hnub no hauv khw muag khoom koj tuaj yeem nrhiav tau bays ntawm LED strips ntawm 50 thiab 100 m. Xws li LED sawb txuas nrog yam tsis muaj hluav taws xob thiab tsim rau thaj chaw loj. Feem ntau, nws yog hnav khaub ncaws hauv lub tes tsho silicone los tiv thaiv cov nag lossis daus hauv huab cua thiab siv tau zoo heev hauv kev tsim ntawm txoj kev, khw qhov rais thiab lwm yam khoom. Koj tuaj yeem kawm paub ntau ntxiv txog cov kab nrib no hauv video hauv qab no.
UPS cov txheej txheem xaiv rau LED strip
Ua ntej yuav khoom siv hluav taws xob, koj yuav tsum ua tib zoo xam cov khoom siv los ntawm tag nrho cov LEDs uas koj npaj yuav txuas rau nws. Ntxiv rau lub zog ntawm txhua ntu ntawm cov kab xev, koj yuav tsum tau ntxiv 15-20%. Yog tias tsis muaj UPS ntawm kev muag khoom nrog raws nraim cov kev txwv no, lawv raug muab sib dhos. Koj yuav tsum tsis txhob yuav lub LED sawb fais fab mov nrog cov yam ntxwv uas muaj zog heevtshaj qhov tsim nyog. Qhov no tsuas yog ua rau cov nqi tsis tsim nyog.
Qhov chaw teeb tsa ntawm UPS ua lub luag haujlwm tseem ceeb. Yog tias koj npaj yuav teeb lub qab nthab, phab ntsa lossis rooj tog hauv chav pw, chav tsev, chav nyob, ces koj tuaj yeem yuav lub hwj chim hauv qhov tsis muaj kev tiv thaiv. Tab sis rau chav dej, chav dej thiab txawm tias chav ua noj, koj yuav tsum tau yuav ib lub cuab yeej nrog kev tiv thaiv noo noo. Hauv qhov no, lub zog hluav taws xob zoo tib yam yuav tsis tsuas yog siv sijhawm ntev, tab sis kuj yuav ua rau muaj kev phom sij. Koj kuj yuav tsum tau xyuam xim rau qhov tso zis hluav taws xob: yog tias daim kab xev tsim rau 12 V, ces 24 V fais fab mov yuav tsuas hlawv nws.
Dab tsi ntxiv koj yuav tsum paub txog LED strips thiab cov khoom siv fais fab
Cov khoom siv zoo li no yuav txawv ntawm kev ua haujlwm. Cov khoom siv hluav taws xob LED kim dua yog nruab nrog cov khoom siv dimming. Nyob rau hauv cov ntaub ntawv no, lub teeb siv tswj system yog ntsia rau hauv qhov chaw ntawm tus qauv hloov. Kuj tseem muaj kev xaiv nrog cov chaw taws teeb tswj, uas yooj yim dua. Hauv qhov no, kev sib txuas lus tuaj yeem ua tau ob qho tib si ntawm infrared thiab xov tooj cua raws.
Cov khoom siv zoo sib xws kuj sib txawv hauv kev cog lus. Qhov loj ntawm cov khoom siv fais fab yuav nyob ntawm nws lub peev xwm. Yog li ntawd, yog tias koj npaj ntau ntu ntawm LED sawb, tsis txhob cia siab tias UPS yuav yog me me.
Sab nraum zoov LED strips thiab lawv siv
Tsis muaj lub nroog Christmas tsob ntoo tuaj yeem ua yam tsis muaj teeb pom kev zoo li no. Tab sis duralight (LED strip 220V yam tsis muaj fais fab mov) tsis yog siv rau hnub so xwb. backlight advertisingbillboards, khw qhov rais, inscriptions ua los ntawm lub teeb khiav - koj yuav tsis sau lawv tag nrho.
Cov kab LED no yog tsim los rau kev ua haujlwm hauv nag thiab daus, raws li tau sau tseg hauv ntau qhov kev tshuaj xyuas. Lawv txuas ncaj qha mus rau lub network, tab sis rau qhov no muaj ib tug diode choj ntawm lub tswv yim. Lub fact tias xws li ib tug kev twb kev txuas yog yooj yim heev tsis ntseeg ntawm cov neeg siv, tab sis qhov no yog precisely lub ntsiab teeb meem (paradoxical raws li nws yuav zoo li). Tus choj diode tsis muaj peev xwm muab kev tiv thaiv kev tiv thaiv hluav taws xob, uas tuaj yeem ua rau tsis ua haujlwm ntawm LED cov ntsiab lus.
Reviews
Kev txiav txim siab los ntawm kev tshuaj xyuas, ntau tus kws tsim khoom hauv tsev txaus siab rau qhov yooj yim thiab kev ua tau zoo ntawm kev teeb tsa lub teeb rov qab nrog LED sawb. Qhov tseem ceeb ntawm no tsis yog ua yuam kev hauv kev xaiv ib tus neeg siv hluav taws xob, thiab tsuas yog kev suav kom raug tuaj yeem pab hauv qhov no. Tab sis cov chaw tsim khoom yuav tsum tsis txhob txo qis ib qho - Suav cov khoom lag luam tsis zoo li yuav txaus siab rau tus tswv rau lub sijhawm ntev nrog kev ua haujlwm tsis muaj kev cuam tshuam. Nws yog qhov zoo dua los them tus nqi siab dua rau ib hom khoom uas tau sawv qhov kev sim ntawm lub sijhawm dua li hloov cov khoom siv hluav taws xob pheej yig txhua 2-3 lub hlis.
