*2020 daim ntawv hloov kho: Ua ntej tshaj plaws kuv tsis siv lub kiv cua ntxiv lawm thiab uas zoo li tsis ua li cas. Nws tau kub, tab sis tseem tsis tau hlawv dab tsi. Nrog qee qhov kev nkag siab tshiab thiab vim tias cov leds yog li pheej yig av, Kuv yuav siv ntau dua li tsuas yog 2 thiab ntxiv qee qhov 3W ib leeg LEDs. Qhov txiaj ntsig ntawm qhov no yog tias 10W LEDs xav tau txog 9V, tab sis lub hwj chim muab tsawg kawg 12V. Siv piv txwv li 10W LED hauv koob nrog 3W LED yuav zaum txo nws txoj kev kos tam sim no. Kev mob siab rau tam sim no tswj hwm cov khoom siv yuav zoo dua tab sis kuv pom qhov no ua haujlwm tsawg kawg 12V cov khoom siv hluav taws xob. Siv 4 LEDs hauv koob (lossis ib leeg 10W + 3W uas yog sib xws, 10W yog 3 leds nyob rau hauv series, thiab tias 3x nyob rau hauv parallel) ua rau tam sim no kos txog 0.2A. Qhov ntxiv hluav taws xob poob los ntawm MOSFET yuav txo qhov ntawd ntau dua, yog li koj tuaj yeem kho nws li no kom ua tau raws li qhov ntsuas tau ntawm koj li 12V lub zog siv. Qhov no tseem yuav ua rau lub hwj chim siab 2 ohm resistor tsis xav tau. Lwm txoj hauv kev yog siv LED strips. Koj tuaj yeem pov 2 ohm resistor, thiab siv lub rhaub dej me me rau MOSFET nkaus xwb.

Cov lus qhia no yog txuas ntxiv ntawm Tshav Tswb Tswb Tswb https://www.instructables.com/id/Sunrise-Alarm-Clock-1/ los ntawm https://www.instructables.com/member/DIY+Hacks+and+How +Tos/. Khab nias rau thawj lub tswv yim thiab txuas mus rau tus tswv cuab ntawd. Kuv tsuas yog yoog raws nws qhov kuv xav tau thiab cov ntaub ntawv ntawm tes. Cov lus qhia hauv qhov txuas txuas ua rau pom lub teeb nrog 5mm LEDs me me, cov lus qhia no yog hais txog lub zog loj LEDs nrog rau tag nrho lub zog theoretical ntawm 20W, uas tshaj qhov tso tawm ntawm 60W cov roj teeb. Kuv mus rau qhov tso zis ntau dua vim tias nws tsis kim heev, sawv nrog lub teeb ci yog noj qab nyob zoo, thiab kuv muaj npe zoo thaum tsis sawv. Yog li kuv tseem yuav siv kuv lub xov tooj ntawm tes ua lub tswb ceeb toom. Kuv tseem tuaj yeem tso lub teeb rau qee lub sijhawm tom qab sawv thiab siv nws ua lub teeb pom kev ib txwm muaj. Tshwj xeeb tshaj yog nyob rau lub caij ntuj no thaum nws tseem tuaj yeem tsaus ntuj sab nraum thaum sawv los qee qhov kaj thaum sawv ntxov tuaj yeem yog qhov zoo rau koj qhov kev sib dhos niaj hnub.

Kauj ruam 1: Cov ntaub ntawv

Raws li ib txwm muaj, koj xav tau qee cov ntaub ntawv. Kuv ib txwm sim siv cov khoom siv ntawm cov laug cam qub txij li lawv tsis tau them nqi dab tsi, thiab ib sab ntawm qhov rov ua dua tshiab yog ib puag ncig zoo. Thaum kuv xav yuav cov khoom kuv feem ntau siv ebay, txij li qee tus neeg muag khoom Suav muab kev xa khoom dawb ntawm cov khoom pheej yig. Qhov tsis zoo yog lub sijhawm thauj khoom;) Siv rau tsuas yog lub teeb tsa sawv nws tus kheej:

• Phab Ntsa Socket Timer Hloov (Kuv nyiam lub digital txij li qhov tsis yog digital uas kuv tau ua ua rau muaj suab nrov tsis txaus ntseeg)
• AC-DC Adapter (Qhov no tau khaws los ntawm tus qauv uas tsis ua haujlwm zoo, tus kws kho mob hloov nws tab sis tsis nco qab coj rov qab lub adapter. Cov lus qhia thib ob uas tau teev tseg yog 12V 2A DC.)
• IRF510 MOSFET (ebay, 1 daus las)
• 4.7 MOhm resistor (~ 1W lossis 2W Kuv xav tias, tab sis cov me me ib txwm yuav ua. Tus nqi tsis tseem ceeb, yuav tsum loj)
• 100 kOhm Potentiometer/resistor kuj sib txawv (Rau qhov ua tau zoo. Tus nqi tsis tseem ceeb tab sis yuav tsum hais 10k+)
• 2200 µF 16V Capacitor (Los yog qee yam zoo sib xws, tsuav koj tsis muaj qhov ntsuas qis dua qhov voltage koj tso rau nws)
• 10W 9-12V 0.9A Sov Dawb COB LED (ebay, 1, 31 daus las)
• 10W 9-12V 0.9A Dawb COB LED (ebay, 1.40 daus las)
• 2 Ohm 10W resistor (ebay, kwv yees li 3 daus las rau 5 pob)
• CPU heatsink nrog 12V kiv cua (khaws los ntawm lub khoos phis tawj qub, tej zaum tsis muaj kiv cua yuav ua, nyob ntawm koj lub rhaub dej kub)
• Circuit Board
• Hlau
• Cov kua nplaum kub
• Kua nplaum
• Rwb thaiv tsev ntsws los yog kab xev
• Qee cov cuab yeej xws li cov laug cam, pliers, thiab lwm yam.

Yeem rau kiv cua:

• Hloov
• Teeb ntawm cov neeg tawm tsam rau khiav lub kiv cua ntawm qhov nrawm tshaj plaws, PWM kuj yog qhov kev xaiv tab sis kuv tau mus rau txoj kev yooj yim tawm. Yog tias kuv rov hais dua kom raug Kuv siv 1 lossis 2W resistor 150Ohm ua ke nrog 0.25W 560Ohm resistor. Kuv tsuas yog khaws qhov ntau tshaj plaws ntawm Ohms uas tus kiv cua tsuas yog cia li khiav.

Nco tseg ntawm qhov tseem ceeb rau lub capacitor, Mohm resistor thiab potentiometer: Cov no tsis tas yuav yog qhov zoo li qhov no, qhov sib txawv sib txawv yuav ua tau zoo xwb (tsuas yog ntsuas yog tias nws yuav ua lossis tsis). Qhov teeb tsa no mus txog lub zog tag nrho hauv li 30 txog 45 feeb, yog li qis qhov tseem ceeb rau Mohm resistor thiab/lossis capacitor yuav zoo dua.
