Hauv Cov Lus Qhia no koj yuav ua lub roj teeb rov ntsuas dua rau cov roj teeb tsis kam sab hauv.
Kuv qhia tias sim ua cov cuab yeej no ua ntej:
Nws yog ib qho tseem ceeb uas tau hais tias kev tiv thaiv sab hauv ntawm lub roj teeb hauv qhov kev tsim no tau xav tias yuav xoom txawm tias rau cov roj teeb tawm. Kuv tsis tau pom dua cov roj teeb zoo li no hauv lub neej tiag. Txawm li cas los xij, yog tias lub roj teeb txuas nrog tus tswj hluav taws xob, hloov hluav taws xob lossis Zenner diode voltage regulator ces qhov no tuaj yeem txo qis kev tiv thaiv sab hauv.
Cov cuab yeej no tsis muaj txiaj ntsig zoo. Txawm li cas los xij, yog tias koj tsis muaj dab tsi zoo dua los ua nrog peb lub xov tooj qub txuas tom qab ntawv thov txuas ntxiv mus.
Hauv Circuit qhia pom LED tau ua qauv nrog peb lub hom phiaj dav dav vim tias PSpice simulation software yog qub heev.
Nrog lub roj teeb muaj xoom them thiab xoom hluav taws xob hla nws cov davhlau ya nyob twg qhov siab tshaj tam sim no nkag mus rau lub roj teeb yuav yog 2.3 V / 100 ohms = 23 mA.
Qhov hluav taws xob hla LED yog kwv yees li 2 V. (3 V - 2 V) / (10 mA) = 100 ohms.
Ceeb Toom: Tsis txhob txuas lub roj teeb uas tsis tuaj yeem them rov qab (piv txwv li - roj teeb alkaline)! Tej zaum lawv yuav kub lossis tseem tawg. Tsis txhob tuav lub davhlau ya nyob twg rau lub roj teeb ntev yog tias koj tsis 100 % paub tseeb tias lub roj teeb tuaj yeem tswj tau 23 mA cov tswv yim tam sim no. Txawm li cas los xij, qhov no tsis tshua muaj tshwm sim.
Vim tias 23 mA tsis yog qhov siab tam sim no (sib npaug rau tsuas yog ob lub LEDs thaum nyob (10 mA txhua)) rau qhov raug txawm tias AAA 1.5 V roj teeb koj tuaj yeem luv cov txiaj ntsig. Txawm li cas los xij, qhov no yuav tso lub roj teeb sai heev.
Txawm li cas los xij, tej zaum koj tseem tuaj yeem siv lub voj voog no los ua lub roj teeb yog tias lub roj teeb tau raug them nrog qhov no (23 mA siab tshaj) tam sim no. Txawm li cas los xij, lub roj teeb yuav tsis them ntau dua 1.3 V vim tias qhov hluav taws xob LED yog 2 V. 2 V - 0.7 V - 1.3 V. Qhov no tuaj yeem yog qhov zoo rau them NiCad cov roj teeb uas yuav tsum tsis txhob them yog tias lawv yuav luag them (1.3 V ntau dua) tshaj li 1.5 V) los tiv thaiv kev ua haujlwm ntawm cov roj teeb ntawd.
Khoom siv
Koj yuav xav tau: - txuas peb -xaim, - ntswj ntsia hlau, - lub zog loj diode, - ob lub 1.5 V them lub roj teeb puv, - ob lub roj teeb 1.5 V, - them 1, 5 V roj teeb thiab tso tawm 1.5 V roj teeb rau kev sim, - ib qho LED xav tau (txawm hais tias kuv siv ob) lossis ob peb yog tias koj hlawv ib, - rwb thaiv kab hlau, - 1 hli hlau xaim, - pliers, - 100 ohm siab zog tiv thaiv, - daim phiaj me me, - laug, - soldering hlau, - hlau stripper, - laum, - txiab.
Kauj ruam 1: Tsim cov tswv yim
Txuas cov tswv yim raws li qhia nrog tus tsav tsheb ntsia hlau.
Cov xov hlau liab thiab dub yog lub roj teeb txuas thiab cov xov hlau dub thiab daj yog lub dav hlau LED.
Kuv siv 47 ohm resistor hloov ntawm 100 ohm resistor vim tias kuv tau ua Circuit nrog ob LEDs. Qhov no ob zaug qhov xav tau tam sim no. Txawm li cas los xij, qhov no yog lub tswv yim pheej hmoo vim tias tam sim no qhov siab tshaj plaws tuaj yeem muaj ntau txog li 50 mA, tsis yog 23 mA. Tsis txhob ua nws tom tsev!
Koj yuav tsum txuas cov hlau hlau nyias los tiv thaiv qhov tshwm sim xaim tawg vim yog khoov ntawm cov xov hlau thaum qhib lub thawv ntau zaus.
Kauj Ruam 2: Tsim Tawm
Txuas cov zis raws li qhia nrog tus tsav tsheb ntsia hlau.
Hauv Circuit no kuv siv Russia qub (Soviet ua) diode. Txhua lub zog loj diode yuav ua txoj haujlwm.
Yog tias koj siv Germanium ntawm Schottky diodes uas muaj qis dua rau qhov tsis ncaj ncees qhov hluav taws xob lub roj teeb yuav tsub kom siab dua 1.5 V thiab ua tsis tiav. Txawm li cas los xij, yog tias koj tsuas yog ntsuas lub roj teeb ces qis dua rau pem hauv ntej tsis ncaj ncees diode voltage yuav ua rau qhov siab tshaj tam sim no txog 29 mA.
Koj yuav tsum txuas cov hlau hlau nyias los tiv thaiv qhov xwm txheej xaim tawg vim yog khoov ntawm cov xov hlau thaum qhib lub thawv ntau zaus.
Kauj Ruam 3: Txuas cov hlua LED
Rau cov kauj ruam no koj yuav xav tau cov hlau txuas.
LED coj hauv ib qho kev qhia xwb. Los ntawm anode mus rau cathode.
"… cathode lead tau luv dua li lwm qhov raws li anode (+) lead ntev dua li cathode (k).", Lub voj voos liab liab tau qhia tias koj yuav tsum txuas cov hlau hlau xaim txhawm rau tiv thaiv qhov xwm txheej xaim tawg vim yog khoov ntawm cov xov hlau thaum qhib lub thawv ntau zaus.
Kauj Ruam 4: Ua Qhov Rau LED
Siv cov laum thiab txiab ua qhov rau LED.
Lus Ceeb Toom: Tig lub txiab maj mam thiab maj mam.
Tom qab ntawd ntxig rau LED Circuit.
Tam sim no koj ua tiav.
