Ua Koj Tus Kheej LED Teeb Hloov Rau Teeb Tsom Teeb: 4 Kauj Ruam

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:30

LED teeb lub teeb zoo nkauj heev nyob rau niaj hnub no, tab sis yog tias koj tshwm sim muaj lub teeb ci teeb pom kev zoo raws li 100 xyoo thev naus laus zis, ntawm no yog koj lub sijhawm kom hloov kho nrog LED uas dhau 8000 xyoo! (yog cov roj teeb muaj tib neeg lub neej) Cov lus qhia no ua li cas: Siv lub teeb PR 2 tsis tu ncua nrog P13.5s puag (piv txwv li cov uas feem ntau pom hauv lub teeb nyem), rov siv lub hauv paus thiab ntxig 3 x 5mm txoj kab uas hla dawb LEDs. Saib daim duab ntawm qhov tshwm sim hauv qab no. Qhov luv rau txoj haujlwm no yog mus rau tom khw thiab yuav ib qho ntawm no. Tab sis hav, dab tsi yog kev lom zem hauv qhov ntawd thaum koj tuaj yeem ua koj tus kheej!

Kauj Ruam 1: Tshem Tawm Lub Teeb Iav

Txoj haujlwm no yog qhov phom sij txaus ntshai, yog li yuav tsum tau ceev faj heev, qhov me me ntawm cov iav tawg tau txiav yooj yim thiab mob heev kom tshem tawm (los ntawm kuv tus kheej ntsib nrog lub raj mis tawg), Kuv hais kom npog lub qhov muag nrog lub phuam hauv chav ua noj thiab maj mam tuav nrog tus plier, twist thiab rub nws tawm.

Lub khob iav yog fused mus rau lub hauv paus hlau nrog cov av nplaum zoo li cov cement, thiab yuav tsum tawg yooj yim. Thaum lub teeb raug tshem tawm, siv lub ntsia hlau me me txhuam cov hlau puag kom huv. Cov phab ntsa sab hauv ntawm lub hauv paus yuav tsum muaj hluav taws xob. Dab tsi sab laug yog pom hauv daim duab hauv qab no.

Kauj Ruam 2: Desoldering qhov seem ntawm Cov iav Qij Los Ntawm Lub Hauv Paus

Ua tiav qhov no, tam sim no koj tuaj yeem ntxig cov ceg LED los ntawm lub qhov, qhov uas nws yuav yog qhov txuas zoo rau lub roj teeb.

Kauj Ruam 3: Txhim Kho Ob txhais ceg ntawm LED

Tam sim no rau qee qhov Uri Geller cov txuj ci khawv koob! Yam koj yuav tsum tau ua yog khoov ob txhais ceg, muab cov anodes tso ua ke (qhov ntawd yog qhov zoo ntawm tus ncej, ntev dua, lossis saib https://en.wikipedia.org/wiki/LED). Cov kab xev me ntsis yuav pab ua kom ruaj khov ua ke thaum koj ua cov laug. Ntxiv tom qab, quav cov ceg cathode rau hauv ib lub u-puab, ntev li 7 hli, cov no yuav tsum tiv nrog cov phab ntsa sab hauv ntawm cov hlau puag. Thaum koj tau ua tiav qhov ntawd, yam koj muaj yog ib yam zoo li cov duab hauv qab no. Qhov no nkag mus rau hauv cov hlau puag, dhau ntawm lub qhov kawg, muab tshuaj txhuam thiab txiav cov protruding tshaj.

Kauj Ruam 4: Cov Lus Cim Tseem Ceeb Kawg

Cov yam ntxwv hluav taws xob ntawm lub teeb LED sib txawv kiag li los ntawm lub teeb ci ib txwm muaj, yog tias koj tau xaiv los siv cov LED dawb, koj ib txwm xav tau tsawg kawg 3.3V txhawm rau qhib nws, ua rau pom lub teeb pom kev zoo tshaj plaws (hais, 3 x 1.2V rechargeable) npib tsib xee hlau hydride), yog tias koj siv LEDs liab, cov no yuav xav tau tsuas yog 2.2V, thiab tuaj yeem siv los ua lub teeb hloov ncaj qha rau 2 lub teeb txawb ntawm tes, tsis muaj teeb meem. Thaum siv LED dawb, txoj kev yooj yim tshaj plaws ntawm kev tsav cov no, yog kev sib txuas hauv kab, nrog cov shunt resistor. Ua haujlwm ntawm qhov muaj txiaj ntsig zoo rau 5mm dawb LED. Rau 3 lub xov tooj ntawm tes, nruab nrab ntawm 3.6V txog 4.5v, nyob ntawm seb koj tab tom siv alkaline lossis them nyiaj rov qab, piv txwv tias yog 4V, nrog cov LED dawb ua haujlwm voltage thiab tam sim no ntawm 3.3V, 30mA feem, (4 - 3.3)/30e^-3, 22 ohm resistor yuav ua. Rau 4 lub xov tooj ntawm tes, nruab nrab ntawm 4.8V txog 6V, piv txwv tias yog nominal ntawm 5.4V, nrog tib yam raug qhov tseem ceeb rau dawb LED, (5.4 - 3.3)/30e^-3, 68 ohm resistor yuav ua. Kev tso ncaj qha ntawm tus tiv thaiv hauv cov hlau hauv paus tuaj yeem txuag koj ntau dua.
