Ukungasebenzi kakuhle kwe-LED kunye nezisombululo
Izibane ze-LED ngokuthe ngcembe zithatha imarike yangoku yezibane zombane ngenxa yokukhanya kwazo okuphezulu, ukusetyenziswa kwamandla aphantsi kunye nobomi obude. Ngokubanzi, izibane ze-LED zinzima ukuphulwa. Kwizibane ze-LED, kukho iingxaki ezintathu eziqhelekileyo: izibane azikhanyi, izibane zimnyama, kwaye izibane ziyadanyaza emva kokucima. Namhlanje siza kuhlalutya ingxaki nganye nganye.
Isakhiwo sokukhanya kwe-LED
Izibane ze-LED zineendlela ezininzi. Kungakhathaliseki ukuba luhlobo luni lwesibane, isakhiwo sangaphakathi siyafana, sahlulwe kwisibane sesibane kunye nomqhubi.
Amaso ezibane
Vula i-casing yangaphandle yesibane se-LED okanye inxalenye yeplastiki emhlophe yebhalbhu. Uyabona ukuba kukho ibhodi yesekethe egqunywe ngoxande olutyheli ngaphakathi. Izinto ezinombala omthubi kule bhodi liliso lesibane. Isibane sesibane sisibane sesibane se-LED, kwaye inani laso limisela ukuqaqamba kwesibane se-LED.
Umqhubi okanye umbane wokukhanya kwe-LED ufakwe ngezantsi kwaye ungabonakali ngaphandle.
Umqhubi unexesha eliqhubekayo, i-step-down, ukulungiswa, ukucoca kunye neminye imisebenzi.
Isisombululo sokusombulula ingxaki xa ukukhanya kwe-LED kungakhanyi ngokwaneleyo.
Xa isibane sicinyiwe, kufuneka uqale uqinisekise ukuba isekethe ilungile. Ukuba kukukhanya okutsha, sebenzisa ipeni yombane ukulinganisa, okanye ufake isibane se-incandescent ukuze ubone ukuba kukho i-voltage kwisekethe. Emva kokuqinisekisa ukuba isekethe ilungile, ungaqala le ngxaki ilandelayo.
Umqhubi okanye ingxaki yombane
Izibane azikhanyi, kwaye ingxaki ibangelwa ngumqhubi. Iidiode ezikhupha ukukhanya zineemfuno eziphezulu zangoku kunye ne-voltage. Ukuba i-current kunye ne-voltage inkulu kakhulu okanye incinci kakhulu, ayikwazi ukukhanyiswa ngokuqhelekileyo. Ngoko ke, abaqhubi abaqhubekayo, abahlaziyiweyo, kunye neebhaksi kumqhubi bayafuneka ukugcina ukusetyenziswa kwabo.
Ukuba isibane asikhanyisi emva kokukhanyisa isibane, kufuneka siqale siqwalasele ingxaki yomqhubi okanye umbane. Ukuba ikhangelwe ukuba yingxaki yamandla, ungabuyisela ngqo unikezelo lwamandla olutsha.
Isisombululo sokukhanya kwe-LED sibe mnyama
Le ngxaki kufuneka isonjululwe kunye nombuzo wangaphambili. Oku kunokuba njalo ukuba ukuqaqamba kokukhanya kumfiliba okanye akukhanyiswanga.
Ingxaki yentsimbi yesibane
Ubuhlalu be-LED bezinye izibane ze-LED zidibaniswe kuthotho. Amaso kumtya ngamnye adityaniswe kuthotho; kwaye iintambo zidibene ngokuhambelanayo.
Ngoko ke, ukuba iliso lesibane livutha kulo mtya, liya kubangela ukuba umtya wezibane ucime. Ukuba intambo nganye ineso lesibane esitshisiweyo, siya kwenza ukuba isibane sicinywe siphela. Ukuba kukho intsimbi etshiswe kumtya ngamnye, qwalasela i-capacitor okanye ingxaki ye-resistor kumqhubi.
Intsimbi yesibane esitshisiweyo kunye neso eliqhelekileyo lesibane linokubonwa kwinkangeleko. Ichaphaza lesibane esitshisiweyo linechaphaza elimnyama embindini, kwaye ichaphaza alinakucinywa.
Ukuba inani lamaso ezibane ezitshisiweyo lincinci, iinyawo ezimbini ezijingayo emva kwentsimbi yesibane esitshisiweyo zinokudityaniswa kunye nentsimbi yokuthambisa. Ukuba inani lezibane ezitshisiweyo likhulu kakhulu, kuyacetyiswa ukuba uthenge intsimbi yesibane ukuyibuyisela endaweni yayo, ukuze ingachaphazeli ukukhanya kokukhanyisa.
Isisombululo sokuqhwanyaza emva kokuba i-LED icinyiwe
Xa ufumanisa ingxaki yokudanyaza kwenzeka emva kokuba isibane sicinyiwe, qinisekisa ingxaki yomgca kuqala. Eyona ngxaki inokwenzeka ngumgca we-zero wolawulo lokutshintsha. Kule meko, kuyimfuneko ukuyilungisa ngexesha lokuphepha ingozi. Indlela echanekileyo kukutshintsha umgca wokulawula kunye nomgca ongathathi hlangothi.
Ukuba akukho ngxaki kunye nesiphaluka, kunokwenzeka ukuba isibane se-LED sivelisa i-self-inductive current. Eyona ndlela ilula kukuthenga i-relay ye-220V kwaye udibanise ikhoyili kwisibane kwichungechunge.
