Yog tias koj xav tau lub zog 10W LEDs, koj tuaj yeem siv tus tsav 3A LED no. Nrog 3 Cree XPL LEDs, koj tuaj yeem ua tiav 3000 lumens!

Kuv hloov kho lub Circuit nrog:

  • IRF9540N transistor
  • Ob lub SS36 diodes ua ke rau qhov ntsuas siab dua tam sim no

Thov koj xav hloov pauv hauv Circuit Court!

Hauv qhov haujlwm, Kuv tau teeb tsa qhov siab tshaj plaws tsav tam sim no rau 2.5A. Koj tuaj yeem sim nrog qhov txiaj ntsig siab dua, xws li 2.9A. Nws zoo li ua rau lub roj teeb saib ntawm 3A. Siv tus inductor nrog qhov ntsuas siab dua tam sim no yuav tsum daws qhov teeb meem.

Yog tias koj tab tom kho qhov kev tawm tswv yim hluav taws xob, xyuas kom tseeb tias koj cov laij lej raug rau qhov kev nkag siab tam sim no tus nqi.

Kuv teeb lub roj teeb saib xyuas qhov kev mus rau 12V SLA roj teeb.

Rau qhov hloov pauv ntau dua, Kuv tau siv 20 MHz siv lead ua oscillator.

Kuv siv tus tsav tsheb LED yav dhau los rau tsav 4 - 700mA liab LEDs siv los ntawm 12V 1.3Ah SLA roj teeb. Kuv txo nws txoj kev tsav tam sim no rau 650mA.

Nov yog cov duab ntawm chav tsev tshiab nrog tus neeg tsav tsheb qis dua.

  • Tsav 10W, 20W, 50W, 100W LED chips los ntawm eBay

Kauj Ruam 6: Txoj Cai Hloov Kho Tshiab rau (Plaub Hlis 17, 2017)

Cov cai no tau hloov kho kom muaj kev pib muag thaum qhib lossis hloov kho nws cov tsav tam sim no. Qhov no tuaj yeem txo nws txoj kev nkag tam sim no thiab txo qhov kev pheej hmoo ntawm cov xim av tawm, txawm hais tias koj tuaj yeem tig rau xim av tawm.

Kauj Ruam 7: Txoj Cai Hloov Kho Tshiab rau (Plaub Hlis 18, 2017)

Cov cai no tau hloov kho tshiab nrog:

  • Kev txo qis hauv kev tsav tsheb tam sim no thaum kaw lossis thaum lub teeb ci ntsa iab dhau mus kom tsis txhob nkag mus tam sim no.
  • 5% nce hauv lub roj teeb txiav tawm qhov hluav taws xob los suav rau cov khoom tiv thaiv. Nws zoo dua rau lub roj teeb thaum koj zam kev them nyiaj ntau dhau
  • Tsawg roj teeb ceeb toom raug tshem tawm kom tiv thaiv kev sib tsoo.

Nws tau hloov kho tshiab vim tias lub microcontroller poob thaum lub ceeb toom roj teeb qis tau ua rau.
