Ukungasebenzi Okujwayelekile Kwe-LED Nezixazululo
Amalambu e-LED kancane kancane athatha imakethe yamanje yamalambu kagesi ngenxa yokukhanya kwawo okuphezulu, ukusetshenziswa kwamandla okuphansi nokuphila isikhathi eside. Ngokuvamile, izibani ze-LED zinzima ukuphulwa. Emalangeni e-LED, kunezinkinga ezintathu ezivamile: izibani azikhanyi, izibani ziyafiphala, nezibani ziyacwayiza ngemva kokucima. Namuhla sizohlaziya inkinga ngayinye ngayinye.
Isakhiwo sokukhanya kwe-LED
Izibani ze-LED zinezinhlobo eziningi. Kungakhathaliseki ukuthi hlobo luni lwesibani, isakhiwo sangaphakathi siyafana, sihlukaniswe ubuhlalu besibani nomshayeli.
Ubuhlalu belambu
Vula i-casing yangaphandle yesibani se-LED noma ingxenye yepulasitiki emhlophe yesibani. Uyabona ukuthi kunebhodi lesifunda elimbozwe ngonxande ophuzi ngaphakathi. Izinto ezinombala ophuzi kuleli bhodi ubuhlalu besibani. Ubuhlalu besibani buyisibani sesibani se-LED, futhi inombolo yakhona inquma ukukhanya kwesibani se-LED.
Umshayeli noma ugesi wesibani se-LED ubekwe phansi futhi awubonakali ngaphandle.
Umshayeli unomshini oqhubekayo, owehlayo, olungisayo, ohlungayo neminye imisebenzi.
Isixazululo sokuxazulula inkinga lapho ukukhanya kwe-LED kungakhanyi ngokwanele.
Lapho ukukhanya kucishiwe, kufanele uqale uqinisekise ukuthi isifunda silungile. Uma kungukukhanya okusha, sebenzisa ipeni likagesi ukukala, noma ufake isibani se-incandescent ukuze ubone ukuthi ikhona yini i-voltage kusekethe. Ngemva kokuqinisekisa ukuthi isifunda silungile, ungaqala ukuxazulula inkinga okulandelayo.
Umshayeli noma inkinga yokuphakelwa kukagesi
Amalambu awakhanyi, futhi inkinga idalwa umshayeli. Ama-diode akhipha ukukhanya anezidingo eziphezulu ku-current and voltage. Uma i-current ne-voltage inkulu kakhulu noma incane kakhulu, ayikwazi ukukhanyiswa ngokujwayelekile. Ngakho-ke, abashayeli abaqhubekayo bamanje, abalungisa kabusha, kanye namarandi kumshayeli kuyadingeka ukuze balondoloze ukusetshenziswa kwabo.
Uma isibani singakhanyiswa ngemva kokukhanyisa isibani, kufanele siqale sicabangele inkinga yomshayeli noma ukunikezwa kwamandla kagesi. Uma kuhlolwa ukuthi kuyinkinga yamandla, ungashintsha ngokuqondile ukunikezwa kwamandla okusha.
Isixazululo sokukhanya kwe-LED sibe mnyama
Le nkinga kufanele ixazululwe kanye nombuzo odlule. Lokhu kungase kube njalo uma ukukhanya kokukhanya kufiphele noma kungakhanyi.
Inkinga yobuhlalu belambu
Ubuhlalu be-LED bamanye amalambu e-LED buxhunywe ochungechungeni. Ubuhlalu entanjeni ngayinye buxhunywe ochungechungeni; futhi izintambo zixhunywe ngokuhambisana.
Ngakho-ke, uma ubuhlalu besibani buvutha kule ntambo, buzokwenza ukuthi intambo yezibani icishe. Uma umucu ngamunye unobuhlalu besibani obushile, lokho kuyobangela ukuba isibani sonke sicinywe. Uma kukhona ubuhlalu obushisiwe entanjeni ngayinye, cabangela inkinga ye-capacitor noma i-resistor kumshayeli.
Ubuhlalu besibani esishile kanye nobuhlalu besibani obujwayelekile buyabonakala ngokubukeka. Ubuhlalu besibani esishile bunechashaza elimnyama phakathi, futhi ichashazi alikwazi ukusulwa.
Uma isibalo sobuhlalu besibani esishile sincane, izinyawo ezimbili ezihlanganisiwe ngemuva kobuhlalu besibani esishile zingadayiswa kanye nensimbi yokunamathisela. Uma inani lobuhlalu bezibani ezishisiwe likhulu kakhulu, kunconywa ukuthi uthenge ubuhlalu besibani ukuze ubeke esikhundleni saso, ukuze ungathinti ukukhanya kokukhanyisa.
Isixazululo sokucwayiza ngemva kokuba i-LED icishiwe
Uma uthola ukuthi inkinga yokukhanyisa kwenzeka ngemuva kokuba isibani sicishiwe, qinisekisa inkinga yomugqa kuqala. Inkinga engenzeka kakhulu umugqa onguziro wokulawula ukushintsha. Kulokhu, kuyadingeka ukuyilungisa ngesikhathi ukuze ugweme ingozi. Indlela efanele ukushintsha ulayini wokulawula kanye nolayini ongathathi hlangothi.
Uma kungekho nkinga ngesifunda, kungenzeka ukuthi isibani se-LED sikhiqiza i-self-inductive current. Indlela elula iwukuba uthenge i-220V relay bese uxhuma ikhoyili nesibani ngochungechunge.
