Uma ufuna ukwazi okwengeziwe mayelana nezici zobuchwepheshe, funda ngezansi ukuze uthole umehluko owengeziwe:
I-12VDC LED strip enobude obufushane bokusika
Ama-chips amaningi e-LED angawodwana asebenza ngamandla e-3VDC kungakhathaliseki ukuthi afakwe kumugqa we-12V noma umugqa we-24V. Eqinisweni, i-chip ye-LED efanayo esebenza emgqeni we-12V ingase ifakwe emgqeni we-24V. Okwenza umehluko ukuthi i-strip circuitry yakhelwe kanjani.
Ama-LED Strip anezintambo ngamaqembu ama-LED. Usayizi we
iqembu lincike ku-voltage ye-strip. Umugqa we-12V unama-LED angu-3, kanti umugqa we-24V unama-LED angu-6 noma ama-LED angu-7, ngisho nama-LED afika kwangu-8. Imigqa enqunyiwe itholakala phakathi kwamaqembu. Ngakho-ke, iqembu ngalinye lama-LED amancane, imigqa yokusika ingaba seduze ndawonye.
Isibonelo, bheka imidwebo yemigqa engu-12V kanye ne-24V ngezansi:
I-voltage ephansi engu-12VDC strip enemigqa esikelwe eduze ingase ibe yinhle uma ukufakwa kwakho kunamakhona amaningi anobude obufushane. Lokhu kungasiza ukunciphisa indawo “emnyama” emakhoneni.
Ukuthola inzuzo ye-Long Run ye-24VDC LED strip kanye nobude obufushane bokusika bomugqa we-5VDC LED, senze I-Mini Cutting LED Strip, I-LED engu-1 ukusikwa ngakunye ku-24VDC.
I-12V LED strip inohlu olubanzi lwezimo zohlelo
Ngakolunye uhlangothi, i-12 VDC iyi-voltage evamile, ngakho-ke ukuhambisana kwe-strip ye-LED kungase kuqede isidingo sokunikezwa kwamandla okungeziwe. Isibonelo, uma ufaka izibani emotweni, ilambu le-12 VDC LED strip ngokuvamile lingaxhunywa ngokuqondile ohlelweni olukhona lukagesi. Nakuba kukhona okuhlukile kulokhu, futhi kubalulekile ukuhlola isistimu yakho ekhona ngaphambi kokuthenga, imichilo ye-12V LED inganikeza isisombululo sokufaka esilula kakhulu ezimweni eziningi.
24V Umugqa we-LED, ukugijima okude komugqa
I-voltage ephezulu kakhulu izokwazi ukusebenza isikhathi eside ngaphandle kokuhlupheka ngenxa yokwehla kwamandla kagesi.
Kuyini ukwehla kwamandla kagesi?
Ukwehla kwamandla kagesi kubangela ukuthi imichilo ye-LED ilahlekelwe amandla njengoba iba mide. Ama-LED ekuqaleni komugqa (eduze nendawo kagesi) azokhanya ngokugqamile. Ngokuphambene, ama-LED ekugcineni komugqa azoba nokubukeka okufiphele.
Kungani ukwehla kwe-voltage kwenzeka?
Noma ibuphi ubude bocingo bunenani elithile lokumelana nogesi. Uma ucingo lunde, kulapho ukumelana khona. Ukumelana nogesi kubangela ukwehla kwamandla kagesi, futhi ukwehla kwamandla kagesi kubangela ukuthi ama-LED akho afiphale.
Ngakho-ke, ama-LED ekugcineni komugqa azohlala ethola i-voltage encane kunalawo asekuqaleni. Uma wenza umucu ube mude ngokwanele, ukwehla kwamandla kagesi kuzoba okuphawulekayo ukuze kubangele umehluko obonakalayo ekugqameni.
I-voltage ephezulu inciphisa kanjani imiphumela yokwehla kwamandla kagesi?
Okokuqala, kufanele uqonde ukuthi zonke izingxenye zomugqa we-LED zixhumeke kanjani.
Ama-chips amaningi e-LED angawodwana asebenza ngamandla e-3V DC kungakhathaliseki ukuthi afakwe kumugqa ongu-12V noma umugqa ongu-24V. Eqinisweni, i-chip ye-LED efanayo esebenza emgqeni we-12V ingase ifakwe emgqeni we-24V. Okwenza umehluko ukuthi i-strip circuitry yakhelwe kanjani.
Ama-LED chips anezintambo ngochungechunge abe ngamaqembu. Iqembu ngalinye liqukethe ama-chips e-LED kanye ne-resistor. Isamba sokwehla kwamandla kagesi eqenjini kufanele silingane nenani lamandla kagesi emucu (bheka imidwebo engezansi).
Bese, iqembu ngalinye lifakwe izintambo ngokuhambisana futhi lihlelwe ngobude bomucu.
Okwamanje, qaphela (imidwebo engenhla) ukuthi usayizi weqembu kumugqa we-24V ungama-LED angu-7 uma kuqhathaniswa nama-LED angu-3 kuphela we-12V. Ngizochaza ukuthi kungani lokhu kubalulekile ngezansi.
Zonke izintambo zinenani elithile lokumelana nogesi ophushwa kuwo. Uma ucingo luba lude, kukhulu ukumelana (kanye nokwehla kwe-voltage). Ekugcineni, iba nkulu ngokwanele ukuba nomthelela ekukhanyeni kwe-LED. Ngezansi kunesibonelo sokuthi kungenzeka kanjani emgqeni we-12V.
Qaphela kulo mdwebo ongenhla ukuthi amandla kagesi kuwo wonke ama-LED ehlile esuka ku-3.0V aya ku-2.75V.
Uma sishintshela ku-24V, kwenzeka izinto ezimbili ezinciphisa ukwehla kwamandla kagesi.
Lapho i-voltage iphindwe kabili (12V kuya ku-24V), yamanje iyancipha (umthetho ka-Ohm P=U * I). Lokho kubangela ukuthi ukwehla kwamandla kagesi ocingweni olude kwehliswe ngesigamu futhi. Ngakho esikhundleni sokwehla kwe-1V, iba ngu-0.5V.
Umthelela wokwehla okungu-0.5V uhlukaniswa phakathi kwezingxenye eziyisishiyagalombili ezisele zesekethe (uma kuqhathaniswa no-4 ku-12V).
Qaphela lapha ukuthi i-voltage kuwo wonke ama-LED yehle yaba ngu-2.9375V kuphela uma iqhathaniswa ne-2.75V enomugqa we-12V.
Uma unohlelo lokusebenza oludinga amapheshana amade, kungase kube umqondo omuhle ukusebenzisa imicu engu-24V. Kodwa, ngisho nemichilo engu-24V inomkhawulo. Kungase kudingeke usebenzise amanye amasu ukumisa ama-LED akho ukuthi angafiphali ekugcineni. Ngokwesibonelo, sebenzisa yethu Imichilo ye-LED yamanje eyi-Super Long Constant.
I-24V LED strip ingaba nokusebenza kahle okuphezulu
I-voltage ephezulu ingasebenza kahle.
Noma nini lapho kukhona i-voltage ku-resistor, kusho ukuthi amandla ashintshelwa ekushiseni esikhundleni sokukhanya. Ngakho-ke, izinto eziphikisayo kule midwebo engenhla ziyadingeka, kodwa futhi ziwumthombo wamandla amoshayo.
| Isamba se-voltage yomugqa | I-voltage ngaphesheya kwe-resistor | % Amandla “achithiwe” kuma-resistors |
| 5V (1 LED Ngeqembu ngalinye) | 2V | 40% |
| I-12V (3 ama-LED Ngeqembu ngalinye) | 3V | 25% |
| I-24V (7 ama-LED Ngeqembu ngalinye) | 3V | 12.5% |
Kulula ukubona ukuthi ama-voltage strips aphezulu ahlushwa amandla amancane amoshwayo. Ama-LED asebenzisa inani elincane lamandla kangangokuthi lokhu akuhlanganisi okuningi ekufakweni okuncane. Kodwa, umehluko ekusetshenzisweni kwamandla ungaba mkhulu kulo lonke igumbi noma ukufakwa kwezentengiso.
Sesithuthukile imichilo ye-LED esebenza kahle kakhulu, 8 LEDs ukusikwa ngakunye, kufika ku-190LM/w.
Lesi yisimiso esifanayo nokudluliswa kwamandla kagesi aphezulu. Ukuphakama kwe-voltage, kuncane okwamanje. Ngokomthetho ka-Ohm, i-voltage drop Vuphonsa=I * R, amandla kagesi aguqulelwe ekushiseni P=U * I = (I * R) * I = I 2 *R.
I-24V LED strip idinga igeji ye-conductor encane
Amandla kagesi anqunywa i-equation P = V * I. Ukuze kugcinwe amandla afanayo (P), uma i-voltage (V) ikhuphuka, yamanje (I) kufanele yehle ngenani elilinganayo.
Uma sigcina u-48W njengokuphuma kwethu okuqondiwe njengesibonelo esiphathekayo, isistimu ye-12V izodinga ama-Amps angu-4 (12V x 4A = 48W), kuyilapho isistimu ye-24V izodinga kuphela ama-Amps angu-2 (24V x 2A = 48W).
Kalula nje, isistimu ye-24V LED izodonsa uhhafu yenani lamanje njengohlelo lwe-12V LED ukuze kuzuzwe izinga elifanayo lamandla.
Kungani lokhu kubalulekile?
Isamba samanje, esikhundleni se-voltage, sinquma ukujiya nobubanzi bamakhondatha ethusi adingekayo ukuze kudluliswe amandla ngokuphepha.
Uma amanani eqile wamanje ephoqelelwa nge-conductor yethusi encane noma emincane, ukumelana ngaphakathi kwekhondatha kuzoba okuphawulekayo futhi kube nomthelela ekwehleni kwe-voltage nasekukhiqizeni ukushisa. Ezimweni ezimbi kakhulu, lokhu kungaholela ngisho nasemililweni kagesi.
Konke okulinganayo, uhlelo lwe-LED lwe-24V lungabaleka nengxenye yezidingo zekhondatha kagesi. Ungasebenzisa yethu i-voltage drop calculator ukuqinisekisa ukuthi usasebenzisa amageji ekhondatha anele kumaphrojekthi akho e-LED strip.
Izinsiza zamandla ezincane zomugqa we-LED ongu-24V
Njengosayizi wekhondatha, usayizi wokuphakelwa kwamandla nawo unqunywa ngokuyinhloko amandla amanje kune-voltage. Ingxenye yalokhu iphinde ithonywe ubudlelwano befiziksi phakathi kwezidingo zamandla kagesi kanye nosayizi wekhondatha, njengoba izintambo eziningi zangaphakathi zeyunithi yokuphakela amandla zihlanganisa izintambo zethusi.
Usayizi wokuphakelwa kwamandla ungabalulekile uma usebenza namaphrojekthi afana nezibani ze-LED ngaphansi kokufakwa kwekhabethe lapho kungase kube khona izingqinamba zesikhala.
