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

Nov yog qhov yooj yim heev thiab pheej yig ($ 1) LED tsav tsheb Circuit. Lub Circuit Court yog "qhov chaw tam sim no", uas txhais tau tias nws ua kom lub teeb ci ci LED tas li txawm tias lub zog siv hluav taws xob koj siv lossis ib puag ncig ib puag ncig ib puag ncig koj raug rau LED li cas.

Los yog muab lwm txoj hauv kev: "qhov no zoo dua li siv tus tiv thaiv". Nws zoo ib yam, muaj txiaj ntsig zoo dua, thiab hloov pauv tau ntau dua. Nws yog qhov zoo tshaj rau Cov Hluav Taws Xob LED tshwj xeeb tshaj yog, thiab tuaj yeem siv rau txhua tus lej thiab teeb tsa ntawm ib txwm lossis lub zog loj LED nrog txhua hom fais fab mov. Raws li txoj haujlwm yooj yim, kuv tau tsim lub tshuab tsav tsheb thiab txuas nws mus rau lub zog loj LED thiab lub zog-cib, ua lub teeb ntsaws. Lub zog hluav taws xob tam sim no nyob ib puag ncig $ 3, yog li qhov no yog qhov haujlwm tsis kim nrog ntau qhov siv, thiab koj tuaj yeem hloov nws kom siv ntau lub LED, roj teeb, thiab lwm yam. sau ntawv & tswv yimTau kab lus no coj tuaj rau koj los ntawm MonkeyLectric thiab Monkey Light lub tsheb kauj vab teeb.

Kauj Ruam 1: Yam Koj Xav Tau

Ib feem ntawm Circuit (xa mus rau daim duab qhia chaw) R1: kwv yees li 100k-ohm resistor (xws li: Yageo CFR-25JB series) R3: teeb tsa tam sim no resistor-saib hauv qab Q1: NPN me transistor (xws li: Fairchild 2N5088BU) Q2: loj N- channel FET (xws li: Fairchild FQP50N06L) LED: fais fab LED (xws li: Luxeon 1-watt lub hnub qub dawb LXHL-MWEC) Lwm qhov chaw: lub zog siv: Kuv siv lub qub "phab ntsa wart" hloov pauv, lossis koj tuaj yeem siv roj teeb. txhawm rau siv hluav taws xob ib qho LED ib yam ntawm 4 thiab 6 volts nrog tam sim no txaus yuav zoo. yog vim li cas qhov Circuit Court no yooj yim! koj tuaj yeem siv ntau yam khoom siv hluav taws xob thiab nws ib txwm ua kom pom qhov zoo ib yam ib yam.heat dab dej: ntawm no kuv tab tom tsim lub teeb yooj yim uas tsis muaj lub rhaub dej txhua. uas txwv peb txog 200mA LED tam sim no. rau ntau tam sim no koj xav tau tso LED thiab Q2 ntawm lub rhaub dej kub (saib kuv cov ntawv hauv lwm lub hwj chim coj qhia kuv tau ua tiav).prototyping-boards: kuv tsis tau siv lub rooj sib tham thawj zaug, tab sis kuv tau ua thib ob ib qho tom qab ntawm lub rooj sib tham proto, muaj qee cov duab ntawm qhov kawg yog tias koj xav siv lub rooj sib tham proto.

xaiv R3: Lub Circuit Court yog qhov txuas tam sim no, tus nqi ntawm R3 teeb tsa tam sim no. Calculations:- LED tam sim no tau teeb tsa los ntawm R3, nws yog kwv yees li sib npaug: 0.5 / R3- R3 lub zog: lub zog tawm los ntawm tus tiv thaiv yog kwv yees li: 0.25 / R3I teeb tsa LED tam sim no rau 225mA los ntawm kev siv R3 ntawm 2.2 ohms. R3 lub zog yog 0.1 watt, yog li tus txheej txheem 1/4 watt resistor zoo. qhov twg kom tau txais qhov chaw: txhua qhov tshwj tsis yog cov LED muaj los ntawm https://www.digikey.com, koj tuaj yeem tshawb rau tus lej muab. cov LED yog los ntawm Cov Khoom Siv Hluav Taws Xob Yav Tom Ntej, lawv cov nqi ($ 3 toj ib LED) zoo dua li lwm tus tam sim no.

Kauj Ruam 2: Cov Lus Qhia & Ua Haujlwm

Ntawm no kuv yuav piav qhia txog kev ua haujlwm hauv Circuit Court, thiab qhov txwv siab tshaj plaws yog dab tsi, koj tuaj yeem hla qhov no yog tias koj xav tau.

Cov lus qhia tshwj xeeb: qhov hluav taws xob tso tawm: 2V txog 18V tso zis hluav taws xob: txog 0.5V tsawg dua qhov hluav taws xob tawm tswv yim (0.5V tso tawm) tam sim no: 20 amps + nrog lub rhaub dej loj Qhov siab tshaj plaws txwv: tsuas yog txwv qhov tam sim no rau Q2, thiab lub zog siv los. Q2 ua raws li qhov sib txawv resistor, nqis qis qhov hluav taws xob los ntawm lub zog xa khoom kom haum rau qhov xav tau ntawm LED's. yog li Q2 yuav xav tau lub rhaub dej kub yog tias muaj lub siab LED tam sim no lossis yog tias lub zog hluav taws xob qhov hluav taws xob ntau dua li cov hlua hluav taws xob LED. nrog lub rhaub dej loj, lub voj voog no tuaj yeem ua haujlwm ntau zog. Q2 transistor tau teev tseg yuav ua haujlwm txog 18V lub zog xa khoom. Yog tias koj xav tau ntau ntxiv, saib kuv Cov Lus Qhia ntawm LED Circuit kom pom tias yuav hloov pauv li cas hauv Circuit. Nrog tsis muaj cua sov dab tsi hlo li, Q2 tuaj yeem tsuas yog nthuav tawm txog 1/2 watt ua ntej kom sov tiag tiag - uas txaus rau 200mA tam sim no nrog txog 3 -volt sib txawv ntawm cov khoom siv hluav taws xob thiab LED. Kev ua haujlwm hauv Circuit: - Q2 yog siv los ua qhov sib txawv resistor. Q2 pib tawm qhib los ntawm R1. - Q1 tau siv los ua qhov hloov pauv qhov kev nkag siab tam sim no, thiab R3 yog "kev xav tiv thaiv" lossis "teeb tsa tus tiv thaiv" uas ua rau Q1 thaum ntau dhau tam sim no ntws. - Lub ntsiab ntws tam sim no yog los ntawm LED's, dhau Q2, thiab dhau R3. Thaum ntau dhau tam sim no ntws los ntawm R3, Q1 yuav pib qhib, uas pib tua Q2. Tig tawm Q2 txo qhov tam sim no los ntawm LED's thiab R3. Yog li peb tau tsim "cov lus tawm tswv yim", uas txuas ntxiv taug qab qhov tam sim no thiab ua kom raws nraim ntawm qhov teeb tsa txhua lub sijhawm.

Kauj Ruam 3: Hlau LED

txuas mus rau LED

Kauj Ruam 4: Pib Tsim Vaj Tsev

Circuit Court no yooj yim heev, kuv tab tom tsim nws yam tsis muaj lub rooj tsav xwm hauv Circuit. Kuv tsuas yog txuas cov kev coj ua ntawm cov khoom hauv nruab nrab cua! tab sis koj tuaj yeem siv lub rooj sib tham me me yog tias koj xav tau (saib cov duab tom kawg rau qhov piv txwv).first, txheeb xyuas tus pin ntawm Q1 thiab Q2. tso cov khoom nyob rau hauv pem hauv ntej ntawm koj nrog daim ntawv lo thiab tus pin, tus pin 1 yog nyob rau sab laug thiab tus pin 3 yog ntawm sab xis. tus pin 1B = tus pin 2C = tus pin 3so: pib los ntawm kev txuas cov xov hlau los ntawm LED-tsis zoo rau tus pin 2 ntawm Q2

Kauj Ruam 5: Khaws Tsev

tam sim no peb yuav pib txuas Q1.

ua ntej, lo Q1 upside-down rau sab xub ntiag ntawm Q2 kom nws yooj yim dua los ua haujlwm nrog. qhov no tau ntxiv cov txiaj ntsig uas yog tias Q2 tau kub heev, nws yuav ua rau Q1 txo qhov kev txwv tam sim no - kev nyab xeeb! - txuas tus pin 3 ntawm Q1 rau tus pin 1 ntawm Q2. - txuas tus pin 2 ntawm Q1 rau tus pin 3 ntawm Q2.

Kauj Ruam 6: Ntxiv tus Resistor

- solder resistor ib ceg ntawm resistor R1 rau ntawd dangling LED-ntxiv xaim

- Siv lwm tus ceg ntawm R1 rau tus pin 1 ntawm Q2. - xa cov xov hlau zoo los ntawm lub roj teeb lossis lub zog txuas mus rau LED-ntxiv rau xaim. tej zaum nws yuav yooj yim dua ua qhov ntawd ua ntej.

Kauj Ruam 7: Ntxiv Lwm Cov Resistor

- kua nplaum R3 rau sab Q2 yog li nws nyob hauv qhov chaw.

- txuas ib tus coj ntawm R3 rau tus pin 3 ntawm Q2 - txuas lwm tus coj ntawm R3 rau tus pin 1 ntawm Q1

Kauj Ruam 8: Ua kom tiav Circuit Court

tam sim no txuas cov xov tooj tsis zoo los ntawm lub zog txuas mus rau tus pin 1 ntawm Q1.

koj nyob nraum ua! peb yuav ua kom nws tsawg dua nyob rau qib tom ntej.

Kauj Ruam 9: Hloov mus tas li

tam sim no sim cov Circuit los ntawm kev siv lub zog. piv txwv tias nws ua haujlwm, peb tsuas yog yuav tsum ua kom nws ruaj khov. ib txoj hauv kev yooj yim yog tso lub blob loj ntawm cov kua nplaum silicone thoob plaws hauv Circuit Court. qhov no yuav ua rau nws muaj zog thiab tsis muaj dej. tsuas yog glob rau ntawm silicone, thiab siv dag zog kom tshem tau cov pa npuas. kuv hu txoj kev no: "BLOB-TRONICS". nws tsis zoo li ntau, tab sis nws ua haujlwm zoo tiag tiag thiab pheej yig thiab yooj yim.

kuj, khi ob lub xov hlau ua ke yuav pab txo qis ntawm cov xov hlau thiab. Kuv kuj tau ntxiv ib daim duab ntawm tib lub Circuit Court, tab sis ntawm daim phiaj xwm txheej (qhov no yog "Capital US-1008", muaj nyob ntawm digikey), thiab nrog 0.47-ohm R3.
