Cov neeg caij tsheb kauj vab feem ntau xav sawv los ntawm cov neeg coob coob thiab ci ci rau lawv ob lub log tsheb. Ib txoj hauv kev los hloov tus qauv yog txhawm rau nruab lub backlight.
Cov Lus Qhia
Kauj ruam 1
Yuav 5 hli LEDs ntawm txhua lub khw muag khoom hluav taws xob. Nco ntsoov tias nws zoo dua tsis txhob coj cov matte li, muaj lub teeb me me los ntawm lawv. Xaiv cov xim ntawm diodes rau koj saj, sab laj nrog tus muag khoom, uas ci ci ci. Koj tseem yuav xav tau 9 Volt roj teeb, xov hlau, kab xev hluav taws xob thiab txhua lub pob, tes hloov khawm.
Kauj ruam 2
Ntsuas qhov kev ncua deb ntawm lub hub mus rau qhov twg lub diode yuav raug teeb tsa ntawm kev hais lus. Txiav cov xov hlau siv sijhawm ntev dua li koj tau ntsuas ua ntej - koj tseem yuav tsum muab lawv txuas rau ntawm diodes. Zoo dua ua txhua yam nrog cov npoo dua ntxiv tom qab.
Kauj ruam 3
Ruaj ntseg cov xov hlau rau LEDs. Sawb qhov xaus ntawm txoj xov hlau, khoov ceg ntawm diodes thiab, muab cov hlau hla ntawm lub txiaj ntsig, maj mam txiav nws. Tom qab ntawd cam cov pob qij txha los ntawm xaiv ib qho hlau soldering thiab cam nrog rosin. Txhawm rau tiv thaiv cov neeg los ntawm oxidizing tom qab dej nkag rau lawv, txheej lawv nrog kua roj vanish lossis silicone. Txuas txhua LEDs hauv series nrog txhua lwm, tawm ntawm ob kawg ntawm cov xov hlau tsis siv - tom qab ntawd txuas lub khawm thiab lub zog txuas rau lawv.
Kauj ruam 4
Siv cov kab xev hluav taws xob los qhwv txhua qhov sib tiv thaiv kom tiv thaiv lawv los ntawm kev sib koom ua ke, thiab tom qab ntawd muab cov ntawv sau ua ke. Qhov no yuav txo tag nrho cov tuab rau qhov loj me ntawm LED, thiab tiv thaiv lub taub hau los ntawm khoov thaum khi ruaj rau cov lus. Qhov no tseem yuav tiv thaiv cov neeg ntawm kev tiv thaiv ib puag ncig los ntawm kev cuam tshuam ntawm ib puag ncig sab nraud.
Kauj ruam 5
Siv lub clamp, muab cov LED coj mus rau cov lus hais, muaj yav tas los qhwv nws nrog kab xev hluav taws xob. Ncaj qha LED rau lub npoo los yog hub raws li koj nyiam. Qhov kev xaiv thib ob muab ntau lub teeb. Nruab qhov khawm nyob rau hauv qhov sib txawv ntawm ib qho ntawm cov xov hlau, kev ruaj ntseg nws mus rau kev hais lus. Tom qab ntawd txuas lub qhov fais fab - roj teeb, uas yog qhov zoo dua rau kev txhim kho ntawm lub tsheb taub hau nrog lub clamp. Tshawb xyuas cov haujlwm ntawm lub Circuit Court: thaum koj nias lub khawm, txhua lub LED yuav tsum taws thaum tib lub sijhawm.
