Indlela yokuxazulula inkinga yokushisa yamapheshana okukhanya kwe-LED

Izizathu nezixazululo zokushisisa imichilo yokukhanya ye-LED

Sivame ukusebenzisa imikhiqizo ye-LED ekuphileni kwethu, futhi imichilo yokukhanya ye-LED isetshenziswe kabanzi ekuhlobiseni nasekuhlobiseni emikhakheni ehlukahlukene eminyakeni yamuva. Ezimweni eziningi, kudingeka ukuthi zisebenze isikhathi eside, okuzobangela ukuthi zilimale ngenxa yokukhanyisa isikhathi eside. imfiva. Ngakho-ke yiziphi izimbangela zomkhuhlane nokuthi ungazixazulula kanjani ngemva kokushisa komzimba? Ake sixoxe ngazo ndawonye.

1. Izimbangela zokushisisa kwamapheshana okukhanya

Kunezizathu eziningi zokushisa komugqa wokukhanya, okuhlanganisa izici ezilandelayo:

1. Ibangelwa ukushisa kwe-LED

I-LED ingumthombo wokukhanya obandayo lowo ngokwethiyori ongakhiqizi ukushisa. Kodwa-ke, ekusetshenzisweni okusebenzayo, ngenxa yokuguqulwa kwe-elekthronikhi okungaphelele kanye nokusebenza kahle kokuguqulwa kwe-photoelectric, inani elithile lokushisa lizokhiqizwa ngezinga elithile, okwenza umugqa wesibani ushise.

2. Ukushisa okungekuhle komugqa wokukhanya

Ukushisa okungekuhle komugqa wokukhanya nakho kuyisizathu esibalulekile sokushisa komugqa wokukhanya. Ukuchithwa kokushisa okungekuhle kwemichilo yokukhanya kubangelwa ikakhulukazi izici ezifana nezintambo ezingenangqondo, idizayini engalungile yerediyetha, noma osinki bokushisa abavinjiwe. Uma ukukhishwa kokushisa kungalungile, umugqa wokukhanya uzoshisa ngokweqile, okuholela ekuphileni okufushane komugqa wokukhanya.

3. Umugqa okhanyayo ugcwele kakhulu

Ukulayishwa ngokweqile kwamapheshana okukhanya nakho kungesinye sezizathu zokuthi kungani amapheshana okukhanya ashise. Uma umugqa wokukhanya umelana nawo mkhulu kakhulu, uzobangela ukuthi umugqa wokukhanya ushise ngokweqile, ubangele okokusebenza ukuthi kuguge, okuholela kumasekhethi amafushane, amasekhethi avulekile, njll.

1. Isimo sesifunda: Izicaciso zamandla kagesi ezivame ukusetshenziswa kakhulu zamapheshana okukhanya kwe-LED yi-12V kanye no-24V. I-12V iyiyunithi yezinhlamvu ezi-3 ezihambisanayo, futhi i-24V iyiyunithi yezinhlamvu ezi-6 ezihambisanayo. Imichilo yokukhanya ye-LED isetshenziswa ngokuxhuma amaqembu amaningi obuhlalu bezibani. Ubude obuqondile bezintambo zokukhanya ezingaxhunywa buhlobene kakhulu nobubanzi besifunda kanye nobukhulu be-foil yethusi ngesikhathi sokuklama. Amandla amanje umugqa wokukhanya ongamelana nawo ahlobene nendawo ehlukanisayo yomugqa. Kufanele ukunake lokhu lapho ufaka umugqa wokukhanya. Uma ubude bokuxhuma komugqa wokukhanya budlula okwamanje obungakwazi ukumelana nawo ngesikhathi sokufakwa, khona-ke umugqa wokukhanya uzokwenza Lapho usebenza, ngokuqinisekile uzokhiqiza ukushisa ngenxa yamanje egcwele ngokweqile, okuzolimaza kakhulu ibhodi lesifunda futhi kunciphise impilo yesevisi yokukhanya. hlubula.

2. Ukukhiqizwa: Imichilo yokukhanya kwe-LED yonke imikhakha ehambisanayo. Uma isifunda esifushane senzeka eqenjini elilodwa, i-voltage yamanye amaqembu emgqeni wokukhanya izokhuphuka, futhi ukushisa kwe-LED kuzokwanda ngokufanele. Lesi simo senzeka kakhulu emgqeni wesibani we-5050. Uma noma iyiphi i-chip yomugqa wesibani we-5050 ine-circuited, i-current ye-short-circuited bead yesibani izophinda kabili, futhi i-20mA izoba ngu-40mA, futhi ukukhanya kobuhlalu besibani nakho kuzoncipha. Kuzokhanya futhi ngesikhathi esifanayo kubangele ukushisa okukhulu, ngezinye izikhathi kushise ibhodi lesifunda phakathi nemizuzu embalwa. Yenza ukuthi umucu wokukhanya we-LED uchithwe. Kodwa-ke, le nkinga ayicacile, futhi ngokuvamile akunakwenzeka ukuba ibonwe, ngoba isifunda esifushane asithinti ukukhanya okuvamile komugqa wokukhanya, ngakho bambalwa abantu abahlola njalo. Uma umhloli ehlola kuphela ukuthi umugqa wokukhanya ukhipha ukukhanya futhi anganaki ukuthi ukukhanya kwe-LED akujwayelekile, noma ehlola kuphela ukubukeka ngaphandle kokuthola ukutholwa kwamanje, khona-ke isizathu sokuthi kungani i-LED ishisa ngokuvamile sizoshaywa indiva, okuyinto izobangela Abasebenzisi abaningi bathi imichilo yokukhanya iyashisa kodwa ayikwazi ukuthola isizathu.

Isixazululo:

1. Khetha umugqa okhanyayo onokusebenza okuhle kokukhipha ukushisa

Uma uthenga umugqa wokukhanya, ungakhetha umugqa okhanyayo ngokusebenza okuhle kokukhipha ukushisa, okunganciphisa ngempumelelo inkinga yokushabalaliswa kahle kokushisa komugqa wokukhanya futhi uvimbele umugqa wokukhanya ekushiseni ngokweqile futhi ubangele ukwehluleka.

2. Yenza idizayini enhle yokulahla ukushisa yomugqa wokukhanya

Kwezinye izindawo ezidinga ukusetshenziswa isikhathi eside, umphumela wokukhipha ukushisa womugqa wokukhanya ungathuthukiswa ngokungeza ama-radiators noma amasinki okushisa. Idivayisi yokukhipha ukushisa ingaphinda idizayinwe ngedizayini yomugqa wokukhanya ukuze ithuthukise ngempumelelo umthamo wokulahla ukushisa womugqa wokukhanya.

3. Gwema ukulayisha ngokweqile umugqa wokukhanya

Uma usebenzisa imichilo yokukhanya, zama ukugwema ukulayishwa ngokweqile, khetha imichilo yokukhanya efanele kanye nempahla kagesi, futhi ubambe izintambo ezinengqondo ukuze ugweme ukugcwala isikhathi eside kwemichilo yokukhanya.

1. Idizayini yomugqa:

Ngokucabangela ukubekezelelana kwamanje, isifunda kufanele senzelwe ukwenza i-wiring ibe banzi ngangokunokwenzeka. Isikhala esingu-0.5mm phakathi kwemigqa sanele. Kungcono ukugcwalisa yonke indawo. Uma kungekho zidingo ezikhethekile, ubukhulu be-foil yethusi kufanele bugqine ngangokunokwenzeka, ngokuvamile buyi-1 ~ 1.5 OZ. Uma isifunda senziwe kahle, ukushisa komugqa wokukhanya we-LED kuzoncishiswa kakhulu.

2. Inqubo yokukhiqiza:

(1) Lapho ushisela iyunithi yesibani, zama ukungavumeli ukuxhumana kukathayela phakathi kwamaphedi ukugwema ukushisela amasekhethi amafushane okubangelwa ukuphrinta okungalungile.

(2) Umugqa wokukhanya kufanele futhi ugweme ukujikeleza okufushane lapho uphesha, bese uzama ukuwuhlola ngaphambi kokuwusebenzisa.

(3) Ngaphambi kokugeleza kabusha, qala uhlole indawo yesichibi, bese wenza ukugeleza kabusha.

(4) Ngemva kokugeleza kabusha, ukuhlolwa okubonakalayo kuyadingeka. Ngemuva kokuqinisekisa ukuthi ayikho isifunda esifushane emgqeni wesibani, yenza ukuhlolwa kwamandla. Ngemuva kokukhanyisa, naka ukuthi ukukhanya kwe-LED kukhanya ngokungavamile noma kumnyama. Uma kunjalo, ukuxazulula inkinga kuyadingeka.

Lesi sihloko sihlaziya izizathu zokushisisa kwamapheshana okukhanya futhi siphakamise izindlela zokuxazulula inkinga yokushisa yamapheshana okukhanya. Sithemba ukuthi ingasiza wonke umuntu ukuthi asebenzise kangcono futhi akhethe imichilo yokukhanya futhi agweme ukwehluleka okubangelwa ukushisa ngokweqile kwemichilo yokukhanya.
