Hauv kev hloov cov khoom siv hluav taws xob, LEDs xa mus rau lub teeb -emitting diodes, feem ntau yog siv los qhia txog qhov tso zis hluav taws xob. Thaum lub tshuab hluav taws xob ua haujlwm, qhov qhib / tawm lub xeev lossis lub teeb ci hloov pauv ntawm LED ncaj qha cuam tshuam cov zis voltage theem.
ADJ stands rau qhov tso zis voltage hloov, uas yog ib tug potentiometer, ib hom ntawm adjustable resistor. Los ntawm kev kho qhov tsis kam ntawm no potentiometer, qhov tso zis voltage tus nqi ntawm lub hwj huam mov tuaj yeem hloov kho kom zoo. Potentiometers feem ntau yog hloov kho siv cov pob qhov rooj, sliders, thiab lwm yam, tso cai rau cov neeg siv los hloov kho kom zoo raws li qhov xav tau.
Hauv kev siv tswv yim, lub luag haujlwm ntawm LEDs thiab ADJs yog qhov tseem ceeb. LEDs muab cov lus tawm tswv yim tam sim ntawm lub hwj huam mov kev khiav hauj lwm, pab cov neeg siv txiav txim siab seb lub hwj huam mov puas ua haujlwm li qub. ADJs muab cov kev xaiv hloov pauv hloov tau, tso cai rau cov khoom siv hluav taws xob hloov mus rau qhov sib txawv ntawm qhov yuav tsum tau ua thiab ua kom ruaj khov thiab txhim khu kev qha cov zis voltage.
Kev nkag siab txog kev ua haujlwm ntawm LEDs thiab ADJs pab tau zoo dua kev siv thiab kev saib xyuas ntawm cov khoom siv hluav taws xob hloov. Txawm hais tias siv txhua hnub lossis kev saib xyuas kev tshaj lij, kev paub txog ob qho kev qhia no muaj txiaj ntsig zoo rau kev txhim kho kev ua haujlwm ntawm lub zog hluav taws xob.
Hauv kev hloov cov khoom siv hluav taws xob, kev siv cov LEDs thiab ADJs kom zoo tuaj yeem txhim kho cov cuab yeej kev ntseeg siab thiab cov neeg siv kev paub. LEDs tso cai rau cov neeg siv kom nkag siab sai sai ntawm lub zog hluav taws xob kev ua haujlwm, thaum ADJs muab cov kev hloov kho tsim nyog los xyuas kom meej tias cov khoom siv hluav taws xob ib txwm ua tau raws li qhov xav tau. Qhov no tsis tsuas yog txhim kho kev siv hluav taws xob zoo xwb tab sis kuj tseem txuas ntxiv cov khoom siv lub neej.
Hauv luv luv, LEDs thiab ADJs ua lub luag haujlwm tseem ceeb hauv kev hloov cov khoom siv hluav taws xob. Lawv tsis tsuas yog pab txhawb kev txhim kho kev ruaj ntseg tab sis kuj txhim kho cov neeg siv kev paub, ua rau lawv yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob niaj hnub tsim.
