Cov ntsiab lus tseem ceeb rau kev txhim kho ntawm tus kheej coj lub teeb strips
Niaj hnub no, muaj ntau ntau LED strips xav tau los ntawm cov neeg siv khoom uas tsis yog cov lus qhia tshwj xeeb thiab yuav tsum tau kho. Txawm li cas los xij, vim tsis muaj kev paub txog qee qhov kev tsis sib xws ntawm LED lub teeb sawb, muaj ntau yam kev cai uas tsis ua raws li cov kev cai, thiab txawm tias nws tau tsim los, nws yuav raug cuam tshuam rau kev siv. Ntawm no, cov tuam txhab teeb pom kev zoo sib tham txog qee qhov kev txiav txim siab tshwj xeeb txog qhov tshwj xeeb customization ntawm LED lub teeb strips rau kev siv ntawm kev yuav cov phooj ywg.
Cov ntsiab lus tseem ceeb rau kev txhim kho ntawm tus kheej coj lub teeb strips
1. Circuit Court tsim:
Lub voj voog ntawm LED lub teeb sawb suav nrog series Circuit Court thiab parallel circuit, nrog rau series-parallel circuit. Qhov kom zoo dua ntawm cov kab hluav taws xob yog qhov tam sim no tsis tu ncua, uas ua rau nws yooj yim dua los tswj cov tsav tam sim no ntawm LED. Qhov tsis zoo yog tias ib qho ntawm LEDs puas lawm, tag nrho cov LEDs yuav tsis teeb, tab sis nws yuav tsis cuam tshuam rau lub neej ntawm lwm LEDs. Qhov kom zoo dua ntawm lub voj voog sib txuas yog tias qhov tsis ua haujlwm ntawm ib qho LED yuav tsis cuam tshuam rau kev siv lwm cov LEDs. Qhov tsis zoo yog tias tsis muaj kev txwv tam sim no ntxiv, ib qho ntawm LEDs yuav raug puas tsuaj, uas yuav ua rau cov tam sim no ntawm ob sab ntawm lwm cov LEDs nce, uas yuav hlawv lwm LEDs. Thiab vim hais tias tus tsav tsheb voltage ntawm ib leeg LED yog tsawg heev, nws yuav ua rau feem ntau ntawm cov voltage. Kev ua hauj lwm tsis muaj txiaj ntsig kuj yog ib qho kev nthuav dav rau cov peev txheej.
Cov kab hluav taws xob sib txuas yog ib qho kev sib txuas rau LED strips tam sim no, vim hais tias ob peb LEDs tau txuas nrog hauv series los ua ib pab pawg, thiab tom qab ntawd txuas nrog rau lwm pawg. Nws tuaj yeem ua rau qhov kev siv ntau tshaj plaws ntawm cov khoom siv hluav taws xob hluav taws xob thiab txo qhov poob ntawm qhov tsis muaj zog. Nyob rau tib lub sijhawm, noj ntau lub LEDs hauv series tuaj yeem ua kom ntseeg tau tias cov tsav tsheb tam sim no ntawm cov LEDs yog tib yam, uas yog qhov tsim nyog rau cov LED tam sim no kom ntseeg tau tias lub neej ua haujlwm ntawm LEDs. Lub series-connected LED teeb pab pawg yog ces txuas nrog nyob rau hauv parallel nrog rau lwm pab pawg neeg los xyuas kom meej tias yog ib pab pawg neeg puas lawm, nws yuav tsis cuam tshuam rau ib txwm siv ntawm lwm pab pawg neeg. Nyob rau tib lub sijhawm, vim tias txhua pab pawg muaj qhov txwv tam sim no, kev pabcuam lub neej ntawm lwm pab pawg yuav tsis cuam tshuam los ntawm kev puas tsuaj ntawm ib pawg.
2. Tus naj npawb ntawm lub teeb hlaws ib 'meter' thiab txiav txoj hauj lwm ntawm LED sawb:
Nyob rau hauv ib txwm muaj xwm txheej, tus naj npawb ntawm LED teeb ib 'meter' yog tsau. Piv txwv li, 1210 muaj 60 teeb, 5050 muaj 30 teeb, thiab qhov tshwj xeeb muaj 60 teeb. Yog tias muaj lwm yam tshwj xeeb uas yuav tsum tau ua, piv txwv li, 50 lub teeb rau ib lub 'meter', uas suav nrog kev hloov kho lub voj voog. Txij li nws feem ntau yog ib pawg ntawm 3 LEDs, yog tias nws yog 50 lub teeb, yuav muaj ib pab pawg uas tsis txaus, tab sis yog tias nws yog ib pawg ntawm ob lub LEDs, qhov kev tiv thaiv ntawm qhov tam sim no limiting resistor yuav nce, uas yuav ua rau extravagance ntawm cov peev txheej. Yog li ntawd, thaum ua customized LED strips nrog tshwj xeeb yuav tsum tau, yuav tsum tau them sai sai mus rau lub xov tooj ntawm lub teeb hlaws dai yog ib tug ntau yam ntawm 3, thiaj li tsis mus ua kom muaj hluav taws xob ntau dhau.
