Nws yog dab tsi?

Lub teeb-emitting diode (LED) daim kab xev nws tus kheej yog hloov pauv rau LEDs yooj yim, uas feem ntau muab tso rau ntawm daim ntawv luam tawm Circuit Board. Nws tsis xav tau kev teeb tsa ib-ntu-nws tau teeb tsa sai thiab yooj yim, thiab cov xov hlau tau muab muag tsuas yog thaum pib. Cov kab dawb ci ci tau tshwm sim nrog rau xim (monochrome) cov kab xev . Cov xim nrov tshaj plaws yog xim liab, daj, ntsuab thiab xiav.

LED sawb yog cov khoom hloov pauv tau yooj yim nrog LEDs soldered rau nws . Cov tsheb npav ("ntxiv rau" thiab "rho tawm" rau cov khoom siv hluav taws xob) tau sib cais tau zoo los ntawm ib leeg - ib qho luv luv tsis suav nrog ntawm no. Rau kev tiv thaiv ib nrab tiv thaiv qhov hluav taws xob nce ntxiv ntawm cov hlua, cov kab hluav taws xob tiv thaiv uas txwv qhov tam sim no tau muab tso rau ntawm qhov tsis tu ncua. Cov khoom siv roj hmab sib xyaw ua ib qho dielectric, sab nraub qaum uas muaj txheej nplaum thiab cov yeeb yaj kiab tiv thaiv uas tsis tso cai rau nws qhuav thaum khaws cia.

Lub hauv paus ntsiab lus ntawm kev tsim cov teeb pom kev zoo no yog kev sib txuas ntawm LEDs. Qhov no tuaj yeem ua tau vim muaj cov neeg tshwj xeeb tiv tauj ntawm lub npav, cais ntawm txhua lwm cov ntsiab lus ntawm lawv txoj haujlwm. Ntawm cov kab hluav taws xob qis, cov LED no tau txuas nrog ua ke, ntawm cov kab hluav taws xob siab-hauv kab . Daim kab xev tuaj yeem raug txiav ua qhov tawg - ua tsaug rau cov phiaj xwm tshwj xeeb raws li nws tau txuas nrog: LEDs tau txuas nrog hauv ib kab nkaus xwb hauv ib pab pawg - thiab cov pab pawg lawv tus kheej, tig mus, tau txuas nrog ua ke. Txiav cov kab xev ntev rau hauv daim luv yog tsuas yog ua tau ntawm cov ntsiab lus cim los ntawm cov khw.

Txij li thaum LED yog cov kab hluav taws xob sib nqus, qhov rov qab sib hloov yuav tsuas yog ua rau qhov tseeb tias nws tsis pom kev . Cov niaj hnub LEDs tso tawm ob peb xyoos dhau los tau mus txog qhov ci ci (lub teeb pom kev zoo) uas nce mus txog 150 lumens ib chav. Nrog xaiv tam sim no kom raug, LEDs tuaj yeem ntev txog 50,000 teev, ntxiv rau, lawv tsis xav tau ntawm kev ua haujlwm. Qhov tsis zoo ntawm LEDs yog qhov xav tau ncaj qha tam sim no (lawv hnav kaum npaug nrawm dua los ntawm kev hloov pauv tam sim no), maj mam txo qhov ci ntawm qhov ci (thaum lub neej kev pabcuam tshaj tawm hauv kev tshaj tawm) thiab tus nqi siab.

LEDs yog, ib tus tuaj yeem hais tias, tau txais txiaj ntsig kev nqis peev yav tom ntej, tab sis tsuas yog nrog kev ua raws nruj rau cov yam ntxwv suav yuav lawv nyob ntev li ntev tau raws li cov chaw tsim khoom cog lus . Yog tias cov LEDs yooj yim tuaj yeem rov muag dua (hloov pauv tawm), thiab lub teeb pom kev yooj yim tuaj yeem hnyav dua, tom qab ntawd cov hlua LED, thaum hloov mus rau lwm qhov chaw, yuav plam nws cov khoom siv tus kheej thiab yuav haum tsuas yog thaum teeb tsa hauv pob tshab hose ntawm txoj kab uas hla me me.

Hom thiab qauv

Txuj ci (qhib) LED strips muaj IP-40 chav tiv thaiv kev ya raws (tsis tiv thaiv los ntawm txaws thiab ya raws). Lawv muaj txiaj ntsig tsuas yog hauv cov chav zoo tib yam - hauv txoj kev hauv tsev, chav pw, kev kawm, hauv qab nthab hauv vaj, thiab lwm yam. Dej tsis sib haum, IP-65/68 chav kawm, tsim rau chav ntub dej nrog ib puag ncig txhoj puab heev, nrog rau txoj kev los nag.

Daim kab xev hauv qab dej, tig mus, muaj txheej txheej txuas thiab tiv thaiv uas tiv thaiv nws los ntawm kev nkag mus hauv dej. Nws tuaj yeem siv tau txawm tias nyob hauv qab dej mus rau qhov tob tob - piv txwv li, los ntawm cov neeg sib txawv thiab cov neeg sib txawv: xws li daim kab xev tau teeb tsa hauv lub taub hau tshwj xeeb, kaw nruj nreem los ntawm dej nkag hauv qab nws lub cev. Txoj kab xev yog qhov tshwj xeeb tshaj yog ci - lawv muaj qhov xav tau loj rau teeb pom kev. Cov kab xev rau chav tau txawv los ntawm kev nthuav dav dav hauv lub teeb ci thiab lub zog: rau kev ua haujlwm niaj hnub nyob hauv qhov tsaus ntuj, lub zog loj (txog kaum tawm watts) yuav tawm, thiab raws li lub teeb hmo ntuj - lawv cov ntu luv luv nrog lub peev xwm txog li ob peb watts.

Monochrome ribbons suav nrog cov khoom lag luam raws li SMD-5050 thiab SMD-3528 LEDs . Cov no yog cov kab xev nrog 30 … 60 LEDs rau qhov ntsuas ntsuas ntawm kab xev. Yog tias koj ntsuas thaj tsam ntawm lub luminaire hauv square metres, tom qab ntawd, coj mus rau hauv tus account lawv qhov kev ntom ntom ntom ntom, tus lej tuaj yeem ncav cuag ib txhiab lub teeb ntsiab lus ib "square". Heterochromic thiab polychrome tapes tau nruab nrog cais microcontrollers rau txhua pawg lossis ntu. Cov ntawd, tau txais lub teeb liab thiab lub zog los ntawm lub hauv paus loj, nyob rau hauv uas "lub taub hau" tus tswj teeb lub teeb luminescence tau teeb tsa. Ua tsaug rau cov yam ntxwv ntawm cov txheej txheem, cov kab xev tuaj yeem ci hauv yuav luag txhua qhov ntxoov.

Yog li, kab xev raws li SMD-3528 sib dhos muaj ib leeg-channel microcircuit-nrog qhov ntev nws tau muab nrog ib leeg-channel nti . Nws qhov ntev yog 3, 5 × 2, 8 × 1, 9 mm. Cov khoom SMD-5050 muaj peb-channel microcircuits-peb lub LEDs (liab, ntsuab thiab xiav) yog "cog" ntawm ib lub microcircuit. Cov xim dawb tau tsim los vim yog qhov ci ib txhij ntawm cov xim liab, ntsuab thiab xiav. Daim ntawv tso tawm yog cov hlua nrog daim kab xev qhwv rau ntawm lawv, ntu ntu yog 5 m ntev. SMD-3528 tus qauv muaj qhov dav ib centimeter, SMD-5050 yog me ntsis thinner: tsuas yog 8 hli.

Yuav ua li cas lo?

Qhov saum npoo uas daim kab xev diode tau kaw yuav tsum tsis txhob muaj plua plav ib puag ncig. Yog li, rau gluing tus kheej-nplaum kab xev, phab ntsa npog nrog cov tshuaj dawb los yog lo nrog cov nplaum thiab ntawv ntsa tsis haum. Yas thiab hlau yuav tsum tau muab ntxuav kom huv thiab qhuav.

Yog tias tsim nyog, degrease nrog cawv, acetone lossis lwm cov kuab tshuaj uas tsis yaj cov yas nws tus kheej (lossis txheej xim / kua roj vanish).

Gluing daim kab xev yog qhov yooj yim heev: daim uas yuav tsum tau txiav tawm, thaum pib uas cov xov hlau rau lub zog xa hluav taws xob tau muab muag, tom qab ntawd cov yeeb yaj kiab tiv thaiv raug tshem tawm ntawm qhov kawg. Qhov kawg yog siv rau qhov pib ntawm gluing . Tom qab ntawd, maj mam tshem cov zaj duab xis tiv thaiv, daim kab xev raug nias raws qhov tshem tawm cov yeeb yaj kiab no - hauv kab ncaj ncaj hla dhau lub dav hlau gluing. Ib lub 'meter' ntawm kab xev tuaj yeem lo rau hauv tsawg dua li ib feeb - qhov kev paub ntau tus tswv muaj, nws yuav ua haujlwm sai dua.

Txij li daim kab xev tuaj yeem ua kom sov me ntsis thaum lub sijhawm ua haujlwm, txhuas muaj cov khoom cua sov zoo tshaj plaws . Kev sib khi cov kab xev uas tsis muaj txheej nplaum hauv qab cov yeeb yaj kiab tiv thaiv tau ua tiav siv cov thermal paste - nws ua cov cua sov zoo ib yam piv rau cov yas ib yam. Txij li aluminium profile tsis pheej yig, daim kab xev tuaj yeem muab lo rau hauv cov yas yas ciav hlau yam tsis muaj lub hau npog.

Qhov tsis zoo ntawm yas yog nws cov thermal conductivity tsawg . Yog li ntawd cov LEDs tsis kub hnyiab ua ntej ntxov los ntawm qhov kub dhau, lawv yuav tsum tau tig los ntawm qhov ci ci los ntawm kev siv qhov hluav taws xob, piv txwv li, sib npaug li 9 … 11 volts (rau 12-volt tapes) lossis 3, 7 … 4, 2 (rau 5-volt tapes). Ib qho ntxiv rau yas yog txhuam ntoo thiab ua cov ntoo ntawm txhua hom. Cov kab xev uas tsis muaj txheej nplaum tau lo rau yuav luag txhua qhov chaw. Cov kua nplaum Moment-1 yuav ua haujlwm zoo rau ntawm no. Rau qhov kev kho kom zoo tshaj plaws, daim kab xev raug nias rau hauv qhov chaw tsis muaj cov ballast resistors thiab LEDs.

Yuav ua li cas txuas?

Kev txuas mus rau 220 V AC network tau tso cai tsuas yog nrog ib qho adapters uas muaj AC rectifier tam sim no. Thiab qhov no tsuas yog ua tiav nrog kev pab ntawm cov hluav taws xob hluav taws xob hluav taws xob zoo, tsim rau ntau pua volts. Hauv qhov xwm txheej yooj yim tshaj plaws, lub zog siv hluav taws xob yog lub tshuab hluav taws xob hloov pauv . Nws muab kev rho tawm galvanic nrog qhov poob qis los ntawm 220 txog 3 … 12 volts. Qhov kev xaiv zoo tshaj plaws yog kev tswj hwm kev tswj fais fab. Txhua yam khoom siv hluav taws xob niaj hnub no ua haujlwm ntawm txoj cai mem tes (tsis yog kab tawm).

Rau 5-volt tapes, txawm tias "them nyiaj" los ntawm lub xov tooj smartphone lossis ntsiav tshuaj yog qhov tsim nyog, muab qhov hluav taws xob zoo li no . Lub charger no tau ntsuas txog li 2 amps. Kev siv tam sim no yog xam yooj yim: lub zog faib los ntawm cov khoom siv hluav taws xob yuav muab tus naj npawb ntawm amperes tam sim no.

Piv txwv li, ib daim kab xev 6 watt (6 x 1 watt LEDs) yuav ntsaws 2 amp 1.2 amp charger.

Txawm li cas los xij, lub zog cia yuav tsum suav nrog qhov poob tam sim no rau cua sov los ntawm LEDs thiab los ntawm tus adapter nws tus kheej . Nws yog qhov yooj yim los txuas cov LEDs: nws tsuas yog qhov tseem ceeb kom tsis txhob cuam tshuam qhov sib txawv ntawm cov khoom siv hloov khoom siv (5 V lossis 12 V) thiab cov tswv yim ntawm LED sawb.
