Cov leeg yog cov txheej txheem ntawm lub qhov rooj uas tas li yuav tsum tau kov thiab tsav. Yog li ntawd, nws yog ib qho tseem ceeb kom paub meej txog qhov pom tsis tu ncua ntawm xws li cov txheej txheem kom lawv tsis tas yuav nrhiav lub sijhawm ntev hauv kev tsaus ntuj. Qhov no yog qhov tseeb tshwj xeeb tshaj plaws ntawm lub tsheb. Tom qab tag nrho, koj pom, txaus ntshai qhov tsis yooj yim thaum hmo ntuj tas li ntxim nyiam qhov chaw ntawm tus kov.
Cov kws tshaj lij qhia pom zoo cov teeb ua kom muaj teeb kom ncaj qha.
Nws yog vim li no uas lub backlight xaiv rau cov leeg tau tsim. Muaj ntau yam ntawm lawv. Tab sis feem ntau yog raws li kev ua haujlwm ntawm LEDs. Xav txog ib qho ntawm cov kev xaiv yooj yim thiab tshaj plaws txhim khu kev qha, raws li koj tuaj yeem ua sai sai ua kom sai ntawm tus kov.
Cov cuab yeej ua haujlwm
Illumination tsam ntawm sab nraud ntawm sab nraud.
Ua ntej tshaj plaws, koj yuav tsum npaj nce ua ntej nrog cov ntaub ntawv tsim nyog thiab cov cuab yeej. Ntxiv mus, nws yog ib qho tsim nyog yuav tsum muaj kev xav kom txhua yam nyob rau ib zaug, txij li ua haujlwm nrog hluav taws xob tsis ua kom ntev, tshwj xeeb yog nws los txog lub tsheb. Yog li koj yuav tsum tau:
- LED teeb lub teeb;
- terminals;
- Nyias xov hlau;
- tshuab;
- ntsia hlau ntswj;
- Riam;
- Insulating daim kab xev;
- tho;
- Super lo;
- Yas CORKS RAU TIV THEMETAL;
- Ammeter;
- Passatia.
Thaum txhua yam koj xav tau yuav npaj tau, txiav txim siab rau koj tus kheej, los ntawm lub qhov rooj twg uas koj xav pib. Cov kws tshaj lij pom zoo pib kos duab Backlight ntawm lub qhov rooj xub ntiag, raws li kev nkag mus rau hluav taws xob ntawm lub tsheb yeej ib txwm tuaj ze ntawm no.
Npaj thiab kev sib txuas ntawm cov xov hlau
Illumination ntawm lub qhov rooj ntawm sab hauv.
Tam sim no mus ua haujlwm. Ua ntej koj yuav tsum tau disassagble lub qhov rooj kov. Qhov no yog ua tiav siv cov ntsia hlau tsim nyog. Tam sim no nqa lub teeb LED thiab tshem tawm cov yas tsev los ntawm nws. Muaj koj yuav pom cov pins nyob rau thaum kawg ntawm lub teeb uas yuav xav tau solder rau kev siv hluav taws xob. Tab sis ua ntej qhov no, nws raug nquahu kom xaim me ntsis thiab muab tso rau ntawm lawv cov chaw me me. Yog li koj yuav poob tawm ntau dua yooj yim dua, thiab kev ua haujlwm zoo yuav zoo dua.
Tshooj ntawm cov ncauj lus: Lub rooj sib tw Transformer ua rau koj tus kheej: cov lus qhia thiab kos duab
Nws tsis tas yuav muaj kev maj nrawm kom muab tso rau ntawm cov xov hlau yas rau kev tiv thaiv, txij thaum muaj qee qhov koj tau los tua lawv kom txog thaum ua tiav. Ntawm qhov tod tes, cov xov hlau kuj yuav tsum tau ua lub teeb cheb thiab muab tso rau ntawm cov terminals ntawm cov lus qhia, tab sis twb muaj ntau dua.
Nrog rau txoj haujlwm no, nws yog ib qho tseem ceeb kom xav txog ib qho tseem ceeb. Raws li txoj cai, lub qhov rooj backlight hauv lub tsheb muaj ob sab: ib qho yog lub teeb ncaj qha uas cov khoom noj khoom haus tseem ceeb yuav los rau ntawm lub teeb ci. Yog li ntawd noj mov nws tuaj yeem mus ncaj qha los ntawm hluav taws xob ib feem ntawm lub tsheb uas nyob ze rau ntawm lub kauj) thiab los ntawm lub rooj daim ntawv qhia chaw, feem ntau qhov no tau pom hauv lub tsheb niaj hnub Hom).
Hauv thawj kis, koj yuav tsum laij qhov ntev ntawm cov kav hlau ua ntej kom nws tau muab cov xov hlau kom yooj yim kom cov xov hlau tsis tiv thaiv lawv cov taw. Hauv qhov xwm txheej thib ob, cov xov hlau feem ntau yog siv me me, txij li lawv qhov chaw nyob tsis mus dhau ntawm qhov chaw kov. Tab sis tseem, ob qho tib si hauv qhov rooj plaub thib ob nws raug nquahu kom siv cov kav hlau ntev, vim lawv tuaj yeem ua kom luv.
Tom qab ntawd, nrog kev pab ntawm Ammeter, koj yuav tsum kuaj xyuas qhov kev sib txuas yog ntawm txhua txoj hlua hlau. Yog hais tias nyob rau hauv hluav taws xob koj nkag siab tsis zoo heev, ces nws yog qhov zoo dua rau chaw sib tham lossis kev pab ncaj qha rau cov hluav taws xob kom tsis muaj teeb meem thaum yav tom ntej.
Txhim kho ntawm cov diode hauv tus kov
Fittings nrog LED Backlight.
Tom ntej no koj yuav tsum tau nruab ib diode ncaj qha rau hauv pob ntawm lub pob ntawm lub ntsej muag nws tus kheej. Ntawm no lub tshuab hluav taws xob yog pab tau. Tab sis thawj zaug sim tso cov diode sab hauv tus kov thiab kho nws ib ntus ntawm qhov rooj. Feem ntau hauv cov tsheb niaj hnub, tus qauv tsim tawm rau koj kom ua li ntawd. Tom qab ntawd, nco ntsoov txuas cov diode rau cov hluav taws xob thiab tshawb xyuas cov haujlwm.
Tshooj nyob rau lub ncauj lus: Vim li cas koj xav tau cov ntsuj plig loj?
Cov kws tshaj lij qhia txog lub teeb txawb DAIOD ib txwm coj ncaj qha - yog li lub teeb yuav zoo tshaj plaws lub teeb pom kev zoo. Tsis tas li, lawv pom zoo txuas lwm xaus ntawm cov hlau rau lub zog hluav taws xob hauv daim ntawv ntawm lub zog-muaj peev xwm-muaj zog yog tias koj tsis xav tau lub ntsej muag zoo tas li. Tab sis yog tias nyob rau qhov tsis tooj, nws ua rau kev nkag siab los daws cov xov hlau rau kev pub luam yeeb sib dua.
Thaum nws npaj tau, ua rau lub cim tsim nyog rau ntawm tus tuav hauv cov chaw uas cov xov hlau yuav muab tshaj tawm thiab qhov twg cov dide yuav pom. Nws tsis yog ib txwm tsim nyog thiab nyob ntawm seb kev tsim qauv muaj ib tug kov. Tab sis yog tias nws tuaj rau qhov no, koj yuav tsum tau ua haujlwm tho, drilling qhov. Laum deter xaiv qhov tsawg kawg nkaus. Tom qab tag nrho, nws yog ua tau kom nce lub qhov, tab sis kom txo - twb tsis muaj txoj hauv kev.
Tam sim no koj tsuas yog yuav tsum tau ua tiav kev sib txuas ntawm cov xaim thiab diode. Tam sim no txhua txoj haujlwm loj dhau, koj tuaj yeem nyab xeeb kev hnav cov khoom siv me me, tom qab uas koj muab lub hnab yas tso rau ntawm lawv, uas tau muab tshem tawm thaum pib.
Raws li rau ib feem ntawm kev noj zaub mov, ntawm no koj yuav tsum tau ua kom insulated nrog cov ntawv me me, tom qab uas tsuas yog hnav kev tiv thaiv yas ntawm cov xaim. Tab sis nco ntsoov tias kev tiv thaiv yog tso rau thaum cov xov hlau LED txuas nrog rau cov xov xwm khoom noj khoom haus.
Ntau cov tshuab hluav taws xob qhia tag nrho cov no los ua kev txhim kho ntawm cov teeb tsa LED ntawm lub qhov rooj. Qhov no yog ua tiav nrog kev pab ntawm ib qho supercucy dog dig. Raws li txoj cai, lub hauv paus ntawm lub teeb ntawm cov npoo yog sau me ntsis, uas nws kov tus kov. Tom qab ntawd nias rau ob peb feeb. Yog li lub teeb yuav tsis tas li pop los ntawm lub qhov ntawm kov.
Yog li, cov tsev ua rau pom ntawm cov leeg ntawm cov leeg ntawm lub qhov rooj hauv lub tsheb tau txiav txim siab.
Ib txoj kev zoo sib xws yog ua los ntawm cov ntsiab lus tseem ceeb rau tag nrho lwm cov leeg, thiab yog tias tsim nyog - thiab nram qab. Ib tug neeg tshiab zoo li no yuav zoo li muaj kev nyuaj, tab sis yog tias koj tsis maj thiab ua tib zoo ua txhua yam, koj yeej yuav muaj qhov tshwm sim zoo, koj yuav muaj qhov tshwm sim zoo, koj yuav xis nyob rau qhov kev siv.
Tshooj ntawm cov ncauj lus: Cov kab hlau txawv txawv ua nws tus kheej: cov lus pom zoo rau lawv cov tsim (duab)
