Voltage poob yog txhais raws li tus nqi ntawm qhov hluav taws xob poob uas tshwm sim los ntawm tag nrho los yog ib feem ntawm lub Circuit Court vim impedance. Cov hlau, cov khoom siv hluav taws xob, thiab txhua yam uas nqa tam sim no yeej ib txwm muaj qhov tsis kam, lossis impedance, rau qhov ntws tam sim no.
Yuav ua li cas voltage poob cuam tshuam rau LED teeb pom kev zoo?
Qhov tseem ceeb ntawm kev poob qis rau LED raws li lub teeb pom kev zoo yog tias LED yuav tsum muaj qhov tsawg kawg nkaus ntawm tam sim no kom lub teeb pom kev zoo. Tsawg tshaj li qhov tsawg kawg nkaus tam sim no tuaj yeem ua rau LED flicker, ua haujlwm tsawg dua, lossis hloov xim. Qhov no feem ntau pom nyob rau hauv ntev khiav ntawm LED daim kab xev teeb. Qhov tshwm sim yog qhov pom kev hloov pauv ntawm cov xim lossis qhov ci sib txawv hauv LEDs ntawm ib qho kawg piv rau lwm qhov.
Yuav ua li cas cov neeg muas zaub zam voltage poob los nrog Diode LED daws teeb meem?
This may be best demonstrated with an example using Diode LED Tape Light. The specifications show that it can run up to 40 feet. Let's make that work using the simple steps below.
Xam cov wattage xav tau.
Cov lus qhia tshwj xeeb hais tias Diode LED Daim kab xev siv 2.09 Watts ib ko taw. Diode LED ntsuas qhov hluav taws xob poob hauv cov khoom thiab xaiv qhov siab tshaj plaws khiav. Yog tias koj nyob hauv qhov kev sim siab tshaj plaws khiav ntev, tsuas yog xam cov wattage ib ko taw lossis ib qho kev sib tw los txiav txim siab tus neeg tsav tsheb muaj peev xwm. Qhov siab tshaj plaws khiav ntawm 40 ko taw yuav xav tau tsawg kawg yog 83.6 Watts kom muaj zog ntawm LED daim kab xev teeb array. (2.09 Watts ib ko taw x 40 ko taw=83.6 Watts)
2. Txheeb xyuas cov kab ntsuas kom zoo kom khiav ntawm tus tsav tsheb thiab LED luminaire.
Diode LED cov khoom lag luam tsuas yog ua haujlwm raws li tau teev tseg tias muaj 3 feem pua lossis qis dua hauv qhov hluav taws xob ntawm Tus Tsav Tsheb thiab LED teeb. Lub degree ntawm voltage poob yog txiav txim los ntawm plaub yam tseem ceeb: voltage input (12V los yog 24V), hlau khiav ntev, hlau ntsuas, thiab tag nrho fixture load siv los ntawm lub teeb pom kev zoo (Watts amps).
Ib tus kws kho hluav taws xob lossis tus neeg tsim khoom siv tau siv daim ntawv qhia hauv qab no los txiav txim siab qhov ntsuas hluav taws xob zoo rau kev teeb tsa. Yog tias hauv peb qhov piv txwv tus neeg tsav tsheb tau teeb tsa 20 ko taw los ntawm Diode LED Daim kab xev lub teeb daim duab thib ob qhia tau tias qhov ntsuas hluav taws xob raug yog 16 AWG.
