Tshaj li 5-10 xyoo dhau los, LED strips tau ruaj khov coj lawv qhov chaw ntawm cov teeb pom kev zoo. Lawv tau siv rau hauv kev lag luam tshaj tawm, los tsim kev cai teeb pom kev zoo thiab tsuas yog kho kom zoo nkauj xwb.
Ib daim kab xev hloov tau nrog LEDs tso rau nws tau coj los ua lub hauv paus. Qhov no tso cai rau koj los tsim kev sib xyaw ua ke ntawm lub teeb fluxes. Kab lus yuav qhia koj yuav ua li cas txuas LED strips rau ib leeg.
Vim li cas ribbon txuas tsis tau?
LED strips yog muag hauv bays ntawm 5 meters, cov LEDs ntawm lawv txuas nrog hauv series. Qhov no txhais tau hais tias lawv tus lej raug xaiv raws li txoj hauv kev uas daim kab xev tuaj yeem ua haujlwm hauv lub network nrog qhov voltage ntawm 12.24 volts. Qhov xwm txheej no ua rau muaj kev txwv rau qhov ntev. Yog hais tias nws siab tshaj 5 meters, ces txoj kev conductive yuav overheat, thiab cov khoom yuav sai sai poob. Piv txwv li, ua kev sib txuas 7LED strips yuav tsis ua haujlwm sib txuas ua ke.
Muaj ob hom kev sib txuas: serial thiab parallel. Ua raws li - qhov no yog thaum txhua tus neeg siv khoom siv hluav taws xob tshiab tau txais tam sim no los ntawm yav dhau los. Thaum nyob rau hauv ib qho kev sib txuas, hluav taws xob yog muab rau txhua tus neeg siv khoom ntawm nws tus kheej.
Yog tias qhov teeb pom kev teeb pom kev xav tau ntau qhov kev sib txuas ntawm LED strips rau ib leeg, qhov no tsuas yog ua tau tib yam nkaus xwb. Txhawm rau ua qhov no, koj yuav tsum siv lub cable ntxiv, uas los ntawm lub zog hluav taws xob yuav muab hluav taws xob rau txhua tus neeg siv khoom. Cov hlau yog coj tib qhov ntev li daim kab xev. Nws hla ntu yuav tsum yog tsawg kawg yog 1.5 hli. Yog tias cov LEDs muaj xim, tom qab ntawd rau kev sib txuas nws kuj yog qhov zoo dua los coj cov xov hlau sib txuas rau cov xim. Qhov no yuav pab txhawb kev txhim kho thiab tiv thaiv lawv los ntawm kev tsis sib haum xeeb.
Parallel txuas
Hom kev sib txuas ntawm LED strips rau ib leeg yog qhov pib ntawm tag nrho cov strips uas koom nrog hauv Circuit Court coj lub zog ntawm ib qho chaw, uas txhais tau hais tias ib qho khoom siv hluav taws xob. Qee lub sij hawm, vim li cas ntawm compactness, lub hwj huam mov yuav tsum tau txo qhov luaj li cas, ces txhua daim kab xev tuaj yeem muaj qhov sib cais, uas ua rau cov khoom siv teeb pom kev zoo nce ntxiv.
Txhawm rau siv lub zog ntawm LED sawb, ib txoj hlua khi nrog ib ntu ntawm 0.75 hli yog txaus. Yog tias ua ntej nws tau hais tias cov kab xev ntxiv yuav tsum tau txuas nrog ib lub xaimseem ntawm 1.5 hli, qhov no tsuas yog tsim nyog rau txhua yam muaj zog. Txawm hais tias txhawm rau muab cov khoom siv hluav taws xob nrog hluav taws xob, qhov hla ntawm 0.75 hli yog txaus, txawm hais tias qhov hluav taws xob hauv cov xov hlau yuav yog 220 volts. Tom qab tag nrho, lub zog tam sim no yuav tsawg dua ntawm sab ntawm LED sawb.
Yuav muaj qhov sib txawv me ntsis ntawm txoj kev LED strips txuas rau ib leeg yog tias lawv muaj xim. Tom qab ntawd ib qho RGB maub los ua rau hauv Circuit Court ntawm lub hwj chim mov thiab LED sawb. Qhov no yog siv tau thaum lub teeb backlight ntev dua 5 meters. Yog hais tias ob peb coils ntawm cov xim ribbons siv rau teeb pom kev zoo, ces yuav tsum tau siv cov xov hlau ntxiv los txuas rau txhua qhov.
Txoj cai sib txuas
Muaj ntu ntu ntawm txhua kab LED. Lawv raug cim nrog ib kab nrog txiab logo. Ntawm no koj tuaj yeem txiav cov khoom yam tsis muaj kev puas tsuaj rau cov hluav taws xob hluav taws xob. Qhov kev xav tau ntawm qhov no tshwm sim thaum koj xav tau los hloov cov cheeb tsam uas hlawv tawm LEDs lossis hloov cov teeb pom kev zoo: ntxiv lossis luv daim kab xev. Koj kuj yuav tsum tau txiav thaum koj xav tau sib sau ua ke ntawm kev sib txuas ntawm LED sawb los ntawm ntu mus rau ib leeg.
Txoj kab txiav yog siv txhua 3 LEDs. Hauv qhov tshwj xeeb, koj tuaj yeem tsis quav ntsej cov kab no, tab sis tom qab ntawd qee qhov LEDs yuav tsis teeb, ntxiv rau koj yuav tau npaj ib lub ncoo rau lub connector.
Siv cov khoom sib txuas
Tsim kom muaj kev sib txuas ntawm LED strips yam tsis muaj kev sib txuas, cov khoom siv tau siv. Lawv tuaj yeem raug cais raws li hauv qab nofeatured:
- Rau kev txuas cov xov hlau mus rau thaj chaw tiv tauj ntawm LED strips. Cov khoom sib txuas no yog siv thaum koj xav tau txuas lub cable los ntawm lub zog hluav taws xob lossis los ntawm RGB maub los.
- Txuas ntu rau ib leeg. Cov connectors no muaj ntau configurations. Lawv ncaj, angular, cruciform thiab ntawm ib lub kaum ntse ntse.
- Rau cov xim xim thiab cov qauv siv LED strips. Lawv txawv ntawm ib leeg ntawm cov lem: cov yooj yim muaj 2 conductive lem, thiab cov xim muaj 4.
- haum rau qhov loj.
Txuas txuas daim kab xev, nws yuav tsum tau npaj. Txhawm rau ua qhov no, koj yuav tsum ua tib zoo xam qhov ntev thiab txiav raws lub Hoobkas kab, tom qab ntawd koj yuav tsum ntxuav cov chaw sib cuag nrog cov ntawv xuab zeb zoo kom tsis muaj oxidation uas tiv thaiv kev sib cuag zoo. Tom qab ntawd, lub hau txuas txuas tau qhib, thiab daim kab xev tau ntxig nrog lub ncoo hauv.
Yog tias koj xav tau sib sau cov kab xev rau hauv ib txoj hlua ntawm lub kaum ntse ntse, ces nws yog qhov zoo dua los siv cov hlua txuas.
Txoj kev sib txuas
Txoj kev txuas ntxiv mus txuas LED strips rau ib leeg yog soldering. Txoj kev no siv tau ntev dua, tab sis yuav tsum tau ua haujlwm hnyav thiab siv sijhawm.
Ua haujlwm, koj yuav xav tau cov ntaub ntawv thiab cov cuab yeej hauv qab no:
- Ntxhais hlau. Lub zog siab tshaj plaws 40 watts. Yog tias koj siv lub zog ntau dua, ces cov kab hluav taws xob yuav dhau los, vim tias lawv yuav txav deb ntawm cov substrate.
- Tin lead solder.
- Rosin lossis soldering acid.
- Heat shrink tubing.
Cov hlua khi hlua uas yuav txuas nrog cov neeg sib cuag yuav tsum yog mos txaus kom nyob rau hauv rooj plaub ntawm dabtsi yog khoov nws tsis ua rau qhov taw tes soldering. Yog li ntawd, rau kev sib txuas nws yog tsim nyog los siv ib tug hlau nrog ib tug ntoo khaub lig seem ntawm 0.35-0.5 hli. Thiab txij li thaum cov khoom siv cable muaj qhov hla ntawm 0.75 hli, koj yuav tsum tau hloov pauv ntawm ib qho mus rau lwm qhov los ntawm kev soldering.
Npaj ua haujlwm
Ua ntej pib, koj yuav tsum tau txiav tawm qhov loj ntawm daim kab xev, npaj cov cua sov shrink tubing 3 cm ntev. Yog hais tias lub LED sawb nyob rau hauv lub plhaub silicone, ces nws yuav tsum tau muab tshem tawm ntawm soldering cov ntsiab lus nrog ib tug clerical riam.
Nta ntawm LED sawb soldering
Ua ntej, lub cable yuav tsum muab faib ua cov xov hlau sib cais, txiav tawm qhov rwb thaiv tsev thiab tawm qhov kawg liab qab. Tom qab ntawd, lawv yuav tsum tau tinned. Ua li no, lawv raug kho nrog cov tshuaj rosin thiab ib txheej nyias ntawm solder yog siv.
Qhov no yog qhov tsim nyog kom cov hlau sib txawv tsis sib xyaw ua ke. Ib yam yog ua tiav nrog cov ntaub qhwv.
Tom qab ntawd koj yuav tsum muab cov cua sov shrink tubing rau ntawm cov xov hlau. Qhov no yog ua ntej soldering. Txwv tsis pub, lawv yuav nyuaj rau muab tso rau.
Tom qab ntawd, cov tinned kawg yog siv rau cov kab hluav taws xob thiab ua kom sov nrog cov hlau soldering. Tom qab ntawd, thaum lub tin solder melts, cua sov nres. Lub tin hardens thiab daim ntawv cog lus yuav muaj zog.
Lub raj cua sov tau txav mus rau sabtiv tauj thiab rhuab nrog lub tshuab ziab plaub hau lossis cov nplaim taws. Tom qab txias, nws nruj nreem haum cov hlau thiab nws cov khoom liab qab.
Qee zaum koj yuav tsum tau ua kev sib txuas los ntawm kev sib txuas cov hlua LED ua ke. Tom qab ntawd cov neeg uas nqa tam sim no raug ntxuav ntawm ob qho tib si. Lub tshav kub shrink tube yog muab tso rau ntawm ib tug LED sawb. Cov kev sib cuag ntawm ib daim kab xev yog sib cais los ntawm cov substrate, thiab ib daim kab xev thib ob yog muab tso rau hauv qhov sib txawv, kom lawv cov lem kov. Tom qab ntawd txhua yam tshwm sim, xws li nyob rau hauv cov ntaub ntawv ntawm cov xov hlau, tsuas yog lub tshav kub shrink tube tsis yog muab tso rau ntawm txhua tus hlau ib leeg, tab sis nyob rau hauv daim kab xev tag nrho, kaw lub hlws ris.
Qhov zoo thiab qhov tsis zoo ntawm soldering
Mating tau nyob rau hauv txoj kev no muaj zog txhua yam ntau dua li nrog lub connector. Tsis tas li ntawd, nws tsis oxidize los yog corrode. Yog tias, thaum siv cov khoom sib txuas, qhov chaw sib cuag tau sov, ces soldering yog dawb los ntawm cov kev tsis zoo no.
Qhov tsis zoo suav nrog cov txheej txheem nyuaj. Koj siv tsis tau nws nyob qhov twg. Soldering yog yooj yim dua nyob rau hauv kab rov tav dav hlau, thiab yog hais tias koj xav tau mus txuas rau qhov chaw nyob rau hauv lub qab nthab, nws yog yooj yim dua los siv connectors. Cov duab ntawm kev sib txuas ntawm LED sawb rau ib leeg qhia meej tias cov khoom sib txuas tau siv ntau zaus. Soldering yuav siv sij hawm ntev dua. Koj yuav tsum muaj kev paub dhau los thiab muaj peev xwm txiav txim siab seb qhov kev sib txuas tau zoo npaum li cas.
