Txawm hais tias LEDs tau tsim rov qab rau xyoo 1962 thiab lawv tau kos rau hauv txhua lub tshuab hluav taws xob txij thaum ntawd los, lub sijhawm ntawm qhov pheej yig thiab teeb pom kev zoo pib tsuas yog xyoo 2000, thaum cov txheej txheem tsim khoom ntawm lub teeb dawb emitting diodes dhau los ua pheej yig, uas txhua tus tuaj yeem them taus. nws. Qhov tsis ua haujlwm tsis tu ncua ntawm cov qij tau hloov pauv sai heev nrog cov qij LED, uas tsis yog tsuas yog siv tau ntev dua, tab sis kuj tseem muaj kev siv hluav taws xob qis dua li cov kab ntawv qub.

Yuav ua li cas txog PL raj? Cov no tau siv ntev heev, tab sis vim qhov tseeb tias rau wattage, nws muab tsuas yog ib nrab ntawm qib teeb pom kev zoo (lumen) ntau dua li cov LEDs thiab lawv kuj muaj tshuaj lom mercury, uas yog lom rau lub ntiaj teb nyob, yog li nws yuav tsum tau muab pov tseg nrog kev saib xyuas zoo.

Cov teeb pom kev ntawm LED tuaj yeem pom niaj hnub no hauv ntau daim ntawv: lub qhov muag teeb, PL lub raj roj fluorescent, coj cov kab, thiab lwm yam.

Feem ntau, kom ua tiav yam tsawg kawg yog 1000 lumen kom piv nrog cov qhov muag teeb tsis tu ncua, kev tsim ua ke ntau dua ib qho LED diode. Nyob rau hauv cov ntaub ntawv ntawm coj-strip, cov LEDs tau muab tso rau ntawm qhov deb ntawm 3-4 cm los ntawm ib leeg. Txhawm rau kom ua tiav qib kev xav tau lub teeb, ib tus yuav tsum suav pes tsawg LEDs nws xav tau. Feem ntau koj yuav raug txwv los ntawm qhov chaw, yog li koj yuav siv cov hlua coj uas nws ntev haum rau qhov chaw uas nws yuav raug teeb tsa.

Kauj Ruam 1: Lub Tswv Yim:

Ok, yog li lub tswv yim tuaj ntawm ib qho ntawm kuv tus phooj ywg qhov chaw, qhov uas kuv xub pom lub iav tom qab hauv chav dej. Kuv tau nyiam txoj kev uas lub teeb "tawm tuaj" ntawm ntug, los tom qab daim iav, teeb pom kev rau phab ntsa tom qab nws. Nws yeej ua tau zoo kawg.

Ua ntej tshaj plaws, cov tsom iav zoo li no tuaj yeem pom nyob txhua qhov chaw, yog li nws yooj yim dua thiab txawm tias pheej yig dua los yuav ib qho.

Txawm li cas los xij, Kuv twb muaj daim iav no, nws zoo heev, yog vim li cas thiaj muab nws pov tseg? Tsis tas li, nws muaj ntau qhov deb nruab nrab ntawm phab ntsa, yog li nws tuaj yeem tsim lub tsev siv hluav taws xob me me thiab LEDs yam tsis muaj teeb meem.

Kauj Ruam 2: Npaj Tshooj

Ua ntej de-mounting daim iav los ntawm phab ntsa chav dej, cia muaj cov npe luv uas koj yuav xav tau:

• LED-sawb. Raws li daim iav qhov loj me, nws tuaj yeem nyob nruab nrab ntawm 3-5 meters. Tau kawg, thaum muaj daim iav loj dua, ua ntej koj yuav tau suav qhov ntev uas koj xav tau. Ua tib zoo saib qhov kub (txias dawb, ib txwm dawb, sov dawb). Hauv chav dej feem ntau lub teeb txias zoo li zoo dua, tab sis nws yog tiag tiag rau ib tus saj. Muaj LED-strip hom uas muaj lub npog silicone. Qhov no yog qhov zoo dua, raws li nws yuav tiv thaiv cov khoom tiv thaiv kev xeb, raws li koj yuav muab tso rau hauv ib puag ncig nrog cov av noo siab (chav dej).
• Fais fab mov: Nco ntsoov tias lub zog siv hluav taws xob tuaj yeem tswj tau tam sim no cov hlua LED yuav xav tau. Qhov tam sim no yuav nce nrog qhov ntev ntawm txoj hlua. Feem ntau, cov chaw tsim khoom tau teev tseg qhov kev siv tam sim no lossis wattage ib 'meter'. Tsis tas li cov khoom siv hluav taws xob tseem ceeb. Txhawm rau hloov Wattage rau tam sim no, siv cov qauv hauv qab no: W = V * A (wattage = muab hluav taws xob x tam sim no). Ua tib zoo saib xyuas qhov hluav taws xob ntawm LED-strip. Feem ntau nws yog 12V, tab sis ib tus tuaj yeem pom 220v lossis 24v. 12V yog qhov zoo dua, raws li koj yuav siv nws hauv qhov chaw noo. Yog tias tsis tsim nyog, vim li cas siv hluav taws xob siab dua? Tsis tas li, yog tias ua tau, tau txais ib qho IP68, tab sis tsawg kawg yog yuav tsum tau txaws pov thawj, yam tsawg kawg.
• Cables: Koj yuav tsum tau txiav cov LED-sawb thiaj li tuaj yeem ua tus ntse tig ntawm lub ces kaum.

Cov Cuab Yeej:

• tooj liab, tooj liab
• thermocontractable tube: qhov no yuav siv los thaiv cov xov hlau tom qab siv tas
• kua nplaum: LED-strips yog tus kheej-nplaum, tab sis tsis tas li. Yog li nws yuav tsis ua mob, yog tias siv kua nplaum ntxiv.
• tiv thaiv iav: raws li koj tau siv, qhov tsom iav tiv thaiv tau qhia zoo.

Kauj Ruam 3: Txiav LED-strips

Ua tib zoo ntsuas daim iav uas koj muaj thiab sim xav txog yuav ua li cas koj yuav tso cov kab xev LED txhawm rau kom tau txais txiaj ntsig zoo tshaj plaws. Nws tsis zoo rau tso lawv sab xis ntawm ntug, zoo li qhov no nws tuaj yeem ua rau tsis zoo yog tias koj saib nws los ntawm ob sab. Muab lawv sib sib zog nqus dhau, lossis ze rau hauv nruab nrab kuj tseem tsis ua haujlwm, zoo li qhov no, koj yuav xoob qhov zoo nkauj ci zoo li lub teeb pom kev los ntawm phab ntsa tom qab.

Yog li qhov zoo tshaj plaws yog tso nws 3-4 cm los ntawm nws cov npoo.

Tsis tas li, xam tias 2-txoj kab xaim xav tau qee qhov chaw kom tuaj yeem khoov tau. 4-5 cm yuav txaus.

Tseem ceeb heev! Thaum koj txiav LED-strips, xyuam xim ntawm cov cim. Feem ntau nws yog tom ntej ntawm + thiab - cov cim thiab lawv muaj 2 daim ntawv tooj liab nthuav tawm. Txiav lawv kom raug nyob rau hauv nruab nrab, yog li koj tuaj yeem txuas ob qho tib si

Txhawm rau tuaj yeem siv lawv ua ke nrog cov npoo, nws tsis ua mob yog tias koj tso qee cov cim rau tom qab ntawm daim iav.

Kauj ruam 4: Soldering

Soldering LED-strips yuav tsum tsis txhob nyuaj. Ua ntej tshaj, xyuas kom tseeb tias, yog tias nws tau txheej nrog txheej txheej silicone, qhov no yuav tsum tau muab tshem tawm ua ntej siv cov laug. Txwv tsis pub, cov hlau yuav yaj cov silicone thiab tsis tsuas yog nws yuav hnov tsw phem, tab sis nws kuj yog tshuaj lom thiab yuav ua rau txoj hauv kev ntawm cov hmoov txhuas.

Ua tib zoo ua ntej muab cov pawm ntawm LED-strips, cov kab me me uas koj yuav siv los txuas rau LED-strips koj tau txiav ntawm cov kauj ruam dhau los. Nco ntsoov, thaum soldering kom hwm tus polarity. Yog tias koj lub xov tooj muaj cov cim xim, feem ntau cov hlau liab yuav tsum yog "+", tus dub yog "-". Nyob rau hauv rooj plaub cable yog dub, ib tus yuav tsum muaj tus cim dawb, qhov no feem ntau yog "-".

Tom qab siv lub tshuab ua kom sov, siv lub raj thermocontractable (txiav 3-4 cm) thiab tom qab ntawd nrog rab phom cua sov (lossis sib zog) ua kom sov nws kom nws nqaim mus rau kab, ua kom muaj rwb thaiv tsev zoo.

Tom qab txhua ntu tau muab sib dhos ua ke, sim nws nrog lub hwj chim thiab ua tib zoo tshuaj xyuas lub zog siv. Yog tias koj cov lus teb raug, nws yuav tsum tsis pub tshaj lub zog siab tshaj plaws uas tau sau rau ntawm lub hwj chim.

Hauv daim duab saum toj no, kev siv hluav taws xob tag nrho ntawm LED-strips yog nyob ib puag ncig 0.5A thiab lub zog hluav taws xob tau ntsuas ntawm 1.0A. Yog li nws yuav zoo.

Ceeb toom:

1) Tsis txhob tshaj qhov siab tshaj plaws uas txhawb los ntawm lub zog siv, txawm tias nws hais tias nws tam sim no muaj tsawg. Yog tias khoom pheej yig, nws tuaj yeem ua rau muaj cua sov ntau dua thiab muaj kev pheej hmoo ntawm hluav taws thiab puas tsuaj

2) Ib txwm insulate lub + thiab - ncej nrog cov raj thermocontractable, thiab xyuas kom tsis txhob txav mus. Yog tias 2 tus ncej txuas nrog, qhov no yuav ua rau luv Circuit Court thiab ua kom sov dhau ntawm ob lub xov hlau thiab lub zog siv

Kauj Ruam 5: Ua ntawv thov LED-sawb thiab Xeem Circuitry

Txawm hais tias koj tau ua raws li kuv cov lus qhia thiab ua tib zoo tshawb xyuas cov khoom siv hluav taws xob tom qab txhua qhov LED-sawb tau muab sib dhos ua ke, tom qab thov LED-sawb rau daim iav (koj yuav xav tau siv cov kua nplaum ib yam), ua qhov kev xeem zaum kawg thiab ua tib zoo saib kev siv tag nrho Ib zaug ntxiv, qhov no yuav tsum tsis txhob tshaj qhov ntsuas tam sim no ntawm lub hwj chim.

Kuj ua tib zoo saib xyuas tias txhua kab sawb teeb nrog tib lub zog thiab txhua LEDs ua haujlwm. Yog tias tsis yog qhov xwm txheej, rov tshuaj xyuas qhov muag thiab xyuas kom tseeb tias koj tsis ua rau LED-sawb puas thaum lub sijhawm ua haujlwm.

Lus ceeb toom: Nws tau qhia kom siv lub hwj chim zoo ib yam hauv daim duab rau kev sim, uas tau teeb tsa tam sim no txwv thiab tseem tuaj yeem ntsuas qib hluav taws xob thiab kev siv tam sim no. Ib txwm pib nrog qhov kev txwv tam sim no teeb tsa yam tsawg kawg, thiab tom qab ntawd maj mam nce nws kom txog thaum nws tsis txwv ib qho ntxiv, tab sis tsis txhob tshaj qhov suav qhov theoretical tus nqi

Qhov no xav tau thiab piav qhia:

Cia peb hais tias koj tau suav tias tag nrho cov LED-strips yuav muaj kev siv tam sim no ntawm 0.5 A. Yog tias koj muab cov khoom siv hluav taws xob, thiab koj pom tias koj qhov txwv tam sim no twb dhau qhov no thiab lub hwj chim tseem tab tom txwv qhov tam sim no, qhov no txhais tau tias qee qhov koj muaj hluav taws xob luv luv thiab koj yuav tau rov tshuaj xyuas cov xov hlau. Tsa qhov txwv tam sim no saum toj no tuaj yeem ua rau puas ntawm cov xov hlau, LED-strip, thiab lwm yam.

Kauj Ruam 6: Txuas Cov Khoom Siv Hluav Taws Xob

Raws li cov kauj ruam kawg, yog txhua yam ua tau zoo, tom qab ntawd peb tuaj yeem txuas lub zog xa khoom.

Ua ntej, nws yuav tsum tau lo rau daim iav, lossis koj tuaj yeem siv daim kab xev nplaum uas yog nplaum rau ntawm ob sab. Tseem nco ntsoov, tias cov xaim liab-dub yog qhov tso tawm thiab xiav-xim av yog 220V cov tswv yim.

Ceeb toom! Tsis txhob pauv lawv! Ua li ntawd yuav ua rau puas ob lub LED-sawb thiab lub zog siv ib yam.

Tsis tas li, hwm qhov tsis sib xws: liab yog +, dub yog -, thaum xim av yog xaim nyob, xiav yog qhov tsis muaj dab tsi.

Tom qab siv cov xaim hluav taws xob, xyuas kom tseeb tias koj tiv thaiv lawv kom raug (saib xyuas tshwj xeeb rau ntu qhov hluav taws xob siab!)

Ceeb toom! Nco ntsoov tias koj tsis yuam kev kov qhov siab, vim koj yuav raug koj tus kheej hluav taws xob.

Yog tias txhua yam ua tiav kom raug, tag nrho cov LEDs yuav tsum tau teeb kom zoo.

Tam sim no nws yog lub sijhawm rov txhim kho daim iav. Koj yuav tsum txuas 2 lub xov hluav taws xob (xim av thiab xim xiav) ua ke nrog cov qij uas twb muaj lawm uas tau teeb tsa hauv chav dej. Nco ntsoov tias koj txiav lub hwj chim los ntawm kev txo cov fuses thiab tseem txheeb xyuas nrog lub ntsuas hluav taws xob ntsuas tus cwj mem uas koj tsis muaj qhov phom sij txaus ntshai.

Nco ntsoov tias koj tseem ua qhov rwb thaiv tsev zoo ntawm no. Yog tias nws tsis tuaj yeem siv cov thermocontractible tubes, koj tuaj yeem hloov nws ntawm no nrog daim kab xev hluav taws xob rwb thaiv tsev.

Thaum txhua yam nyob hauv qhov chaw, rov tshuaj xyuas dua thiab tom qab ntawd koj tuaj yeem nce lub fuses dua.

Kauj Ruam 7: Xaus

Lub teeb nrig ntawm daim iav muab lub ntsej muag zoo rau koj chav dej. Yog tias koj tau ua tib zoo ua txhua kauj ruam, qhov teeb tsa no yuav ua haujlwm tau ntau xyoo.

Raws li kev txhim kho yav tom ntej:

Hloov ntawm ib-xim LED-sawb, ib tus tuaj yeem siv qhov programmable RGB sawb thiab ESP8266 microcontroller:
