I-24V ye-LED strip, umgama omde wokuqhuba
Uluhlu lwamandla ombane oluphezulu luya kukwazi ukuhamba ixesha elide ngaphandle kokubandezeleka kwiziphumo zokuhla kwamandla ombane.
Yintoni ukuhla kwamandla ombane?
Ukuhla kwe-voltage kubangela ukuba imicu ye-LED ilahlekelwe ngamandla njengoko iba nde. Ii-LED ekuqaleni komtya (ekufutshane nonikezelo lwamandla) ziya kukhanya ngokuqaqambileyo. Ngokwahlukileyo, ii-LEDs ekupheleni komtya ziya kuba nembonakalo emfiliba.
Kutheni ukuhla kwamandla ombane kwenzeka?
Nabuphi na ubude bocingo bunomlinganiselo othile wokumelana nombane. Xa ucingo lude, ngakumbi ukuxhathisa. Ukunganyangeki kombane kubangela ukuhla kwamandla ombane, kwaye ukuhla kwamandla ombane kubangela ukuba ii-LED zakho zibe luzizi.
Ke ngoko, ii-LEDs ekupheleni komtya ziya kuhlala zifumana amandla ombane amancinci kunalawo asekuqaleni. Ukuba wenza umtya ube mde ngokwaneleyo, ukuhla kwamandla ombane kuya kubaluleka ngokwaneleyo ukuze kubangele umahluko obonakalayo ekukhanyeni.
Ingaba amandla ombane aphezulu anciphisa njani ifuthe lokuhla kwamandla ombane?
Okokuqala, kufuneka uqonde ukuba onke amacandelo akwi-strip ye-LED aqhagamshelwe njani.
Uninzi lweetshiphusi ze-LED zisebenza kumandla e-3V DC nokuba zixhonywe kumcu we-12V okanye umtya we-24V. Ngapha koko, i-chip efanayo ye-LED esebenza kumtya we-12V inokuxhonywa kumtya we-24V. Yintoni eyenza umahluko yindlela i-strip circuitry eyilwe ngayo.
Iitshiphusi ze-LED zifakwe kwingcingo ngokulandelelana ngokwamaqela. Iqela ngalinye liqulethe ezinye iitshiphusi ze-LED kunye ne-resistor. Ukwehla kwamandla ombane kwiqela lonke kufuneka lilingane nombane opheleleyo we-strip (jonga imizobo engezantsi).
Emva koko, iqela ngalinye lifakwe ngokunxuseneyo kwaye licwangciswe ngobude bomcu.
Okwangoku, qaphela (imizobo engentla) ukuba ubungakanani beqela kwi-strip ye-24V yi-7 LEDs xa kuthelekiswa ne-3 kuphela ye-LED ye-12V. Ndiza kuchaza ukuba kutheni oku kubalulekile apha ngezantsi.
Ucingo ngalunye lunomlinganiselo othile wokuxhathisa umbane otyhalwa kuwo. Xa ucingo luthatha ixesha elide, ukuxhathisa okukhulu (kunye nokwehla kombane) ufumana. Ekugqibeleni, iba nkulu ngokwaneleyo ukuchaphazela ukukhanya kwe-LED. Apha ngezantsi ngumzekelo wendlela enokuthi yenzeke ngayo kumtya we-12V.
Qaphela kulo mzobo ungentla ukuba amandla ombane kwii-LED zehla ukusuka kwi-3.0V ukuya kwi-2.75V.
Xa sitshintshela kwi-24V, kwenzeka izinto ezimbini ezinciphisa ukuhla kwamandla ombane.
Xa i-voltage iphindwe kabini (12V ukuya kwi-24V), yangoku iyancipha ngesiqingatha (umthetho we-Ohm P = U * I). Oko kubangela ukuhla kwamandla ombane ukusuka kucingo olude kuncitshiswe ngesiqingatha ngokunjalo. Ke endaweni yokuhla kwe-1V, iba yi-0.5V yehla.
Umphumo wokuhla kwe-0.5V uhlukaniswe phakathi kwezinto ezisibhozo ezisele zesekethe (xa kuthelekiswa ne-4 kwi-12V).
Qaphela apha ukuba i-voltage kwii-LED zehla kuphela kwi-2.9375V xa kuthelekiswa ne-2.75V kunye ne-strip ye-12V.
Ukuba unesicelo esifuna imitsi emide yemigca, inokuba luluvo olulungileyo ukusebenzisa imicu ye-24V. Kodwa, kunye nemicu ye-24V inomda. Kuya kufuneka usebenzise ezinye iindlela zokumisa ii-LED zakho ukuba zingafihli ekugqibeleni. Umzekelo, sebenzisa yethu Iintambo ze-LED ezinde ezinde zangoku.
I-24V ye-LED strip ingaba nokusebenza okuphezulu
Amandla ombane aphezulu angasebenza ngakumbi.
Naliphi na ixesha kukho i-voltage kwi-resistor, oko kuthetha ukuba amandla aguqulwa abe bubushushu endaweni yokukhanya. Ke ngoko, izichasi kule mizobo ingentla ziyimfuneko, kodwa zikwangumthombo wamandla asetyenzisiweyo.
| Umbane opheleleyo we-strip | I-voltage kwi-resistor | % Amandla “achithiwe” kwizixhasi |
| 5V (1 LED ngeQela) | 2V | 40% |
| I-12V (ii-LED ezi-3 ngeQela ngalinye) | 3V | 25% |
| I-24V (ii-LED ezi-7 ngeQela ngalinye) | 3V | 12.5% |
Kulula ukubona ukuba imichiza yamandla ombane aphezulu inengxaki yokuchithwa kancinci kwamandla. Ii-LED zisebenzisa isixa esincinci samandla kangangokuba oku akudibanisi ukuya kuthi ga kufakelo oluncinci. Kodwa, umahluko kusetyenziso lwamandla unokubaluleka kwigumbi lonke okanye kufakelo lwentengiso.
Siye saphuhlisa imichilo ye-LED ephezulu, ii-LED ezi-8 ngokusikwa, ukuya kuthi ga kwi-190LM/w.
Lo ngumgaqo ofanayo nokuhanjiswa kwamandla ombane aphezulu. I-voltage ephezulu, encinci yangoku. Ngokomthetho ka-Ohm, i-voltage drop Vimenyu=I * R, amandla ombane aguqulelwe kubushushu P=U * Mna = (I * R) * I = I 2 *R.
I-24V ye-LED strip ifuna igeji yomqhubi omncinci
Amandla ombane anqunywe yi-equation P = V * I. Ukugcina amandla afanayo (P), ukuba i-voltage (V) iya phezulu, i-current (I) kufuneka yehle ngexabiso elilinganayo.
Ukuba sigcina i-48W njengemveliso yethu ekujoliswe kuyo njengomzekelo wekhonkrithi, inkqubo ye-12V iya kufuna i-4 Amps (12V x 4A = 48W), ngelixa inkqubo ye-24V iya kufuna kuphela i-2 Amps (24V x 2A = 48W).
Ukubeka nje, inkqubo ye-24V ye-LED iya kutsala isiqingatha semali yangoku njengenkqubo ye-LED ye-12V ukufezekisa inqanaba lamandla afanayo.
Kutheni oku kubalulekile?
Itotali yangoku, kunokuba i-voltage, imisela ubukhulu kunye nobubanzi bee-conductor zobhedu ezifunekayo ukuhambisa amandla ngokukhuselekileyo.
Ukuba izixa ezigqithisileyo zangoku zinyanzeliswa nge-conductor encinci okanye emxinwa yobhedu, ukuchasana ngaphakathi kwe-conductor kuya kuba yinto ebalulekileyo kwaye kube negalelo ekunciphiseni umbane kunye nokuveliswa kobushushu. Kwiimeko ezinzima kakhulu, oku kunokukhokelela kwimililo yombane.
Yonke enye into ilingana, inkqubo ye-24V ye-LED inokuhamba nesiqingatha seemfuno zomqhubi wombane. Ungasebenzisa i isixhobo sokubala sokuhla kwamandla ombane ukuqinisekisa ukuba usasebenzisa iigeyiji zomqhubi ezaneleyo kwiiprojekthi zakho ze-LED strip.
Ukubonelela kwamandla amancinci kwi-24V ye-LED strip
Njengobungakanani be-conductor, ubungakanani bonikezelo lwamandla bukwamiselwa ngokuyintloko ngumbane endaweni yangoku. Inxalenye yoku ikwaphenjelelwa lubudlelwane befiziksi phakathi kombane wangoku kunye neemfuno zesayizi ye-conductor, njengoko uninzi lweyunithi yonikezelo lwamandla iingcingo zangaphakathi ziquka iintambo zobhedu.
Ubungakanani bobonelelo lwamandla lunokubaluleka xa usebenza neeprojekthi ezifana nezibane ze-LED strip phantsi kofakelo lwekhabhathi apho kunokubakho imiqobo yendawo.
