Hauv Cov Lus Qhia no, Kuv yuav qhia koj yuav ua li cas thiaj tsim lub teeb rooj LED los ntawm cov khoom seem. Tsuas yog cov LEDs, cov xov hlau, thiab cov khoom siv hluav taws xob, koj tuaj yeem tau txais lwm cov khoom siv dawb. Nyob ntawm qhov chaw koj tau txais cov khoom, koj tuaj yeem tsim nws rau qis dua $ 5. Feem ntau, 3 watt LED teeb raug nqi $ 20. Lub teeb no siv txog 5 watts, uas yog qhov hloov pauv tau zoo rau lub teeb me me fluorescent.

Hauv txoj haujlwm no, koj yuav kawm tsim lub teeb ci LED los ntawm cov hlau tuaj yeem, cov hlua hlau, cov yas yas, cov ntoo ntoo, thiab qee yam khoom siv hluav taws xob.

Kauj Ruam 1: Cov Khoom thiab Cov Cuab Yeej

Khoom siv

• Hloov
• 3 - 1 watt sov dawb LEDs
• N-channel MOSFET (IRF540) thiab NPN transistor (2N3904)
• 1.33 thiab 100k ohm resistors
• 26 gauge xov
• 2 tus ntsia hlau thiab 2 tus ntsia liaj qhov rooj thiab txiv ntseej nrog lub tshuab ntxhua khaub ncaws
• 12V fais fab mov (9V hloov pauv yuav muab rau koj 12V)
• Epoxy
• Kub kua nplaum
• Heatsink muab tshuaj txhuam
• Ntoo ntoo
• Corrugated yas board
• Hlau khuam khawb ncaws
• Dav tuaj yeem nrog hlau puag

Cov cuab yeej

• Kub kua nplaum
• Pliers
• Soldering hlau
• Laum tsav tsheb
• Sanding cuab yeej los yog cov cuab yeej ntse
• Tin snips

Kauj Ruam 2: Npaj Teeb Pom Kev

Xaiv Xaiv Thaum xaiv lub peev xwm, xyuas kom hauv qab yog hlau kom nws ua kom sov cov LEDs thiab tus tswj hwm tam sim no. Qhov loj nws yog, ntau wattage nws tuaj yeem ua haujlwm. Xav tias dawb sim 3W LEDs. Nrog rau 15 cm dav tuaj yeem, qhov ntsuas kub tsis tshaj 40 ° C tom qab siv lub teeb tsis tu ncua. Lim lub peev xwm Lub teeb txawb yuav tsum txiav qis hauv qab ntawm lub raj mis, tawm ob nti ntawm nws qhov siab. Cov npoo txiav yuav tsum tau ua daim ntawv thiab muab tais nrog tus plier. Tsis txhob txiav koj tus kheej thaum ua qhov no. Ntau cov LEDs thiab MOSFET Txhawm rau teeb lub LEDs thiab MOSFET, thov tso heatsink paste rau nruab nrab thiab epoxy rau sab ntug. Nias lawv mus rau thaj chaw tiaj tus ntawm lub peev xwm thiab cia nws kho ua ntej yuav siv tau.

Kauj Ruam 3: LEDs thiab Tsav Tsheb

Solder Three White LEDs in SeriesSelect a Power SupplyWhite LEDs have a forward voltage of about 3.5V. Rau peb LEDs, qhov hluav taws xob rau pem hauv ntej yuav yog 10.5V, thiab lub zog yuav tsum yog 12V. Yog tias koj siv cov hloov pauv qub, 9V hloov pauv tuaj yeem muab 12V rau koj thaum qhov tam sim no qis dua. Kuv siv MOSFET tus tswj hwm tam sim no hloov pauv, thiab kuv muaj peev xwm tsim nws yam tsis muaj lub rooj sib tham hauv Circuit Court thiab siv cov cua sov-ntsws tubing los tuav thiab tiv thaiv cov ntu. Epoxy tau siv los ua kua nplaum rau hauv lub peev xwm. Koj tuaj yeem siv LM317 yog tias koj nce lub zog siv hluav taws xob, tab sis muaj lub sijhawm zoo uas koj tuaj yeem ntxiv ib qho LED ntxiv yog tias koj siv MOSFET tus tsav tsheb. Rau tus tswj hwm tam sim no, Kuv xaiv 1.33 ohm rau R3, thiab tam sim no kwv yees li 0.42 A. Nco ntsoov xyuas nrog lub ammeter. Add a Switch Nrog txoj hlua hla lub qhov, ntxiv cov kua nplaum kub nyob ib puag ncig nws. Twist xoob xaim ua ke

Kauj Ruam 4: Teeb Teeb

Txiav ib Daim Ntawv Corrugated Plastic Board Nws yog nyob ntawm koj xaiv qhov siab ntawm koj lub teeb. Rau kuv lub teeb, qhov ntev ntawm lub rooj yas tau kwv yees li 30 cm los ntawm 5 cm. Ntau txhawb lub Rooj Tswjhwm Saib Cov Yas nrog Cov Hlau Ruaj Ntseg Vim tias daim yas yas yog qhov muag heev, kuv txhawb nws nrog ob daim hlau dai rau ntawm ob sab, tawm hauv chav rau ntsia hlau thiab ntsia liaj qhov rooj, tso cai rau nws khoov kom coj lub teeb mus rau qhov koj xav kom nws nyob.

Rau ib daim 30 cm, ib tus dai khaub ncaws feem ntau txaus. Koj yuav tau ncaj nws thiab muab nws hla lub qhov ntawm lub rooj yas. Qhov kawg ntawm txhua ntu yuav tsum tau khoov kom lawv tsis txhob poob tawm. Kuv siv 15cm los ntawm 9cm los ntawm 4 cm plank ntawm no. Txhawm rau kom sawv ntsug, ntswj cov yas yas rau sab ntawm cov ntoo ntoo. Thaum ntsia hlau rau ntawm lub rooj yas, nws yog lub tswv yim zoo los siv lub tshuab ntxhua khaub ncaws kom lawv tsis txhob poob rau hauv. Qhov Lub Teeb Pom Kev Mus Rau Lub StandTo txhawm rau txhim kho nws mus rau qhov sawv ntsug, laum qhov nkag mus rau lub teeb txawb ze ntawm lub xov tooj hluav taws xob thiab siv cov txiv ntseej thiab ntsia liaj qhov rooj. kom lawv ruaj ntseg.

Kauj Ruam 5: Tus Nqi Ntawm Cov Khoom

Tus nqi kwv yees ntawm Txhua Yam 3 - 1 watt LEDs = 1.40 MOSFET = $ 2.50 Tus Khaub Ncaws = Dawb Yas Sawb = Dawb Ntoo Plank = Tsis paub 12v adapter = Dawb Hlau tau = Dawb Resistors thiab transistors = $ 0.50
