Ukhethe isilawuli sokukhanya komgwaqo selanga esifanele?

Esinye sezingxenye ezibaluleke kakhulu ze-aisibani somgwaqo selangayisilawuli, esivumela ukukhanya ukuthi kuvuleke ebusuku futhi kucime ekuseni.

Ikhwalithi yayo inomthelela oqondile ebude besikhathi sokukhanya komgwaqo welanga kanye nekhwalithi iyonke. Ngamanye amazwi, isilawuli esikhethwe kahle sehlisa izindleko zizonke, sinciphise ukulungiswa nokugcinwa kwesikhathi esizayo, futhi songe imali ngaphezu kokuqinisekisa ikhwalithi yokukhanya komgwaqo welanga uqobo.

Iyiphi indlela engcono kakhulu yokukhetha isilawuli sezibani zasemgwaqweni selanga?

I. Uhlobo Lokukhipha Isilawuli

Uma ukukhanya kwelanga kukhanya kuphaneli yelanga, iphaneli iyashaja ibhethri. Kodwa-ke, kubalulekile ukuqaphela ukuthi le voltage ivame ukungazinzile, okunganciphisa isikhathi sokuphila kwebhethri ngokuhamba kwesikhathi. Isilawuli sibhekana nale nkinga ngokuqinisekisa ukuthi i-voltage ephumayo izinzile.

Kunezinhlobo ezintathu zokukhipha amandla okulawula: abalawuli bokukhipha abajwayelekile, abalawuli bamanje abaqhubekayo be-boost, kanye nabalawuli bamanje abaqhubekayo be-buck. Uhlobo oluthile okufanele lukhethwe luncike ohlotsheni lokukhanya kwe-LED olusetshenziswayo.

Uma isibani se-LED ngokwaso sinomshayeli, isilawuli sokukhipha esijwayelekile sanele. Uma isibani se-LED singenamshayeli, uhlobo lokukhipha isilawuli kufanele lukhethwe ngokusekelwe enanini lama-chip e-LED.

Ngokuvamile, ngokuxhumeka kwe-10-series-multiple-parallel, kunconywa isilawuli samandla kagesi esihlala njalo se-boost; ngokuxhumeka kwe-3-series-multiple-parallel, kukhethwa isilawuli samandla kagesi esihlala njalo se-buck.

II. Izindlela Zokushaja

Abalawuli banikeza nezindlela ezahlukene zokushaja, ezithinta ngqo ukusebenza kahle kokushaja kwesibani somgwaqo selanga. I-voltage ephansi yebhethri iholela ekushajeni okunamandla. Ibhethri lishajwa ngokushesha yisilawuli sisebenzisa ugesi walo ophezulu kanye ne-voltage kuze kube yilapho i-voltage yokushaja ifinyelela umkhawulo ophezulu webhethri.

Ibhethri lishiywa liphumule isikhashana ngemva kokushaja ngamandla, okuvumela i-voltage ukuthi yehle ngokwemvelo. Amanye ama-terminal ebhethri angase abe nama-voltage aphansi kancane. Ngokubhekana nalezi zindawo ezinama-voltage aphansi, ukushaja kwe-equalization kubuyisela wonke amabhethri esimweni sokushaja ngokugcwele.

Ukushaja okuntantayo, ngemva kokushaja ngokulingana, kuvumela i-voltage ukuthi yehle ngokwemvelo, bese igcina i-voltage yokushaja engaguquki ukuze ishaje ibhethri njalo. Le ndlela yokushaja enezigaba ezintathu ivimbela ngempumelelo izinga lokushisa langaphakathi lebhethri ukuthi likhuphuke njalo, okuqinisekisa kangcono isikhathi sayo sokuphila.

III. Uhlobo Lokulawula

Ukukhanya kanye nobude bezibani zasemgwaqweni zelanga kuyahlukahluka kuye ngendawo kanye nezimo zezulu. Lokhu kuncike kakhulu ohlotsheni lwesilawuli.

Ngokuvamile, kunezindlela ezisetshenziswa ngesandla, ezilawulwa ukukhanya, kanye nezilawulwa isikhathi. Imodi esetshenziswa ngesandla ivame ukusetshenziswa ekuhlolweni kwezibani zasemgwaqweni noma ezimweni ezikhethekile zomthwalo. Ukuze kusetshenziswe ukukhanya okuvamile, kunconywa isilawuli esinezindlela ezilawulwa ukukhanya kanye nezilawulwa isikhathi.

Kule modi, isilawuli sisebenzisa amandla okukhanya njengesimo sokuqala, futhi isikhathi sokuvala singasethwa ngokuya ngezimo ezithile zemvelo, sivale ngokuzenzakalelayo ngemva kwesikhathi esibekiwe.

Ukuze kube nemiphumela emihle yokukhanya, isilawuli kufanele sibe nomsebenzi wokufiphaza, okungukuthi, imodi yokwabelana ngamandla, elungisa ngobuhlakani ukufiphaza ngokusekelwe ezingeni lokushaja kwebhethri emini kanye namandla alinganisiwe esibani.

Uma sicabanga ukuthi amandla ebhethri asele angasekela kuphela ikhanda lesibani elisebenza ngamandla aphelele amahora ama-5, kodwa isidingo sangempela sidinga amahora ayi-10, isilawuli esihlakaniphile sizolungisa amandla okukhanyisa, sinciphise amandla ukuze sihlangabezane nesidingo sesikhathi. Ukukhanya kuzoshintsha ngokukhishwa kwamandla.

IV. Ukusetshenziswa Kwamandla

Abantu abaningi bakholelwa ukuthi izibani zasemgwaqweni zelanga ziqala ukusebenza ebusuku kuphela, kodwa empeleni, isilawuli siyadingeka ukulawula ukushaja kwebhethri emini nokulawula ukukhanya ebusuku.

Ngakho-ke, isebenza amahora angama-24 ngosuku. Kulokhu, uma isilawuli ngokwaso sisebenzisa amandla amaningi, sizothinta ukusebenza kahle kokukhiqizwa kwamandla kwesibani sasemgwaqweni selanga. Ngakho-ke, kungcono ukukhetha isilawuli esisebenzisa amandla amancane, okungcono kakhulu cishe i-1mAh, ukuze ugweme ukusebenzisa amandla amaningi kakhulu.

V. Ukushabalalisa Ukushisa

Njengoba kushiwo ngenhla,isilawuli sokukhanya komgwaqo welangaisebenza ngokuqhubekayo ngaphandle kokuphumula, ikhiqiza ukushisa ngokungenakugwenywa. Uma kungekho zinyathelo ezithathwayo, lokhu kuzothinta ukusebenza kahle kokushaja kwayo kanye nesikhathi sayo sokuphila. Ngakho-ke, isilawuli esikhethiwe sidinga nedivayisi enhle yokususa ukushisa ukuqinisekisa kangcono ukusebenza kahle kanye nesikhathi sokuphila kwesistimu yonke yokukhanya komgwaqo welanga.
