Khawm hlwb tuaj yeem muaj peev xwm los ntawm kwv yees li 45 txog 100 mAh. Yog li ib LED kos 1mA yuav kav li ntawm 45 mus rau 100 teev. Ntau LEDs yog dim heev ntawm 1 mA. Raws li Duracell, tus qauv CopperTop AA cell muaj peev xwm nruab nrab ntawm 2000 thiab 3000 mAH nyob ntawm seb nws ua li cas yog siv thiab yuav ua li cas kawg ntawm lub neej yog txiav txim siab.

Yog li, ntev npaum li cas lub tsheb roj teeb tuaj yeem siv teeb ci LED?

Ib yam tsheb roj teeb nrog inverter ua tau muaj zog ib incandescent teeb teeb rau 1.5-3 teev (60-100 watts), CFL teeb rau 9-17 teev (14-23 watts), lossis 9-watt LED teeb rau 29 teev thiab tseem tuaj yeem pib qhov tsheb cav

Ib yam li ntawd, ntev npaum li cas lub roj teeb 9v lub zog LED? Tus Neeg Paub Zoo. ib 9V roj teeb yuav muab koj qhov chaw nyob nruab nrab ntawm 120 thiab 200 teev ntawm illumination nrog qhov yooj yim Circuit Court, ib tug series resistor. Nrog ib tug zoo switching voltage converter Circuit Court koj yuav tsum tuaj yeem tau txais ntau dua 600 teev.

Ntxiv mus, koj puas tuaj yeem khiav LED teeb tawm ntawm lub roj teeb?

LED teeb yog ib txoj hauv kev zoo rau kev txuag nyiaj hauv tsev. Lawv kav ntev li ntau teev, thiab maj mam siv lub teeb ua tau kav ntev txog 25 xyoos. Feem ntau LED teeb npaj kom lawv tau khiav tawm ua 12v roj teeb -Ib., 12 v teeb tau ua rau luv thaum ntsaws ncaj qha rau hauv lub qhov (socket), uas feem ntau muaj 110v tam sim no.

Lub roj teeb 3v yuav siv sijhawm ntev npaum li cas rau LED?

Ntev npaum li cas lub Lithium 3 V CR2032 Npib Cell Roj teeb kawg? Ib yam LED siv li 20mA thiab lub peev xwm ntawm CR2032 Npib Cell yog 200mA. Saib hauv qab no rau a roj teeb kwv yees lub neej: Tus naj npawb ntawm LED (s) hauv ib lub voj voog: 1 - Roj teeb lub neej: 10 teev.
