Ukuqonda Okuyisisekelo Komshayeli We-LED
Iyini i-LED Driver
An Umshayeli we-LED inikeza amandla afanele kuma-LED. Kuyabasiza ukuthi basebenze ngokuphepha nangempumelelo. Isebenza njenge-ballast kumalambu e-fluorescent. Ngaphandle kwayo, ama-LED angashisa kakhulu futhi alimale. Umshayeli ulawula i-voltage kanye ne-current ukuze amise lokhu.
Izici ezibalulekile ze- Umshayeli we-LED kukhona i-voltage yokufaka, i-voltage ephumayo, izinketho zamanje, kanye nezinketho zokufiphala. Abanye abashayeli abathuthukile bakuvumela ukuthi ushintshe izilungiselelo zokusetshenziswa okuhlukile. Ukusebenzisa umshayeli kusiza ama-LED ahlale isikhathi eside futhi asebenze kangcono.
Izinhlobo zama-LED Driver: Constant Current vs. Constant Voltage
Kunezinhlobo ezimbili eziyinhloko ze- Abashayeli be-LED: I-voltage yamanje kanye ne-voltage engaguquki. Uhlobo ngalunye lusetshenziselwa izidingo ezahlukene.
Isici | Umshayeli Wamanje Oqhubekayo | I-Constant Voltage Driver |
|---|---|---|
yamanje | Ihlala injalo | Izinguquko |
voltage | Izinguquko | Ihlala injalo |
Abashayeli bamanje abaqhubekayo bagcina isimanje singanyakazi. Zinhle kakhulu kuma-LED anamandla amakhulu. Lezi zishayeli zinikeza ukukhanya okulinganayo futhi zivikele ama-LED kusukela kumanje kakhulu. Kodwa uma i-LED eyodwa ochungechungeni iphuka, abanye bangase bayeke ukusebenza.
Abashayeli be-voltage abaqhubekayo banikeza i-voltage engashintshi. Alula ukusetha futhi anganika amandla ama-LED amaningi ndawonye. Uma i-LED eyodwa iphuka, ezinye zisasebenza. Kodwa zidinga umkhawulo wamanje futhi zisebenza kancane kunezishayeli zamanje zamanje.
Izici Eziyinhloko Ongazicabangela Kumklamo Womshayeli We-LED
Lapho wenza i Umshayeli we-LED, ibhalansi izindleko nokusebenza. Gxila kulawa maphuzu abalulekile:

Indlela Yokuklama Umshayeli Wakho We-LED
Ukukhetha Izingxenye Ezifanele
Ukukhetha izingxenye ezinhle kuyisihluthulelo sokwenza umshayeli oqinile we-LED. Okokuqala, thola ukuthi ama-LED akho adinga amandla angakanani. Lokhu kuncike ku-voltage yabo kanye namanje. Isibonelo, ama-LED ayisithupha ane-3V ngalinye adinga u-18W wamandla. Ukuze uphephe, khetha ukunikezwa kwamandla okunamandla angu-20% ngaphezulu, njengo-25W.
Okulandelayo, nquma uhlobo lomshayeli oludingayo. Isiguquli esiqhubekayo samanje se-boost sisebenza kahle kuma-LED anamandla amakhulu. Igcina ukukhanya kuzinzile futhi iyeke ukushisa ngokweqile. Uma usebenzisa ama-LED amaningi, isishayeli se-voltage esingaguquki singaba ngcono. Futhi, hlola usayizi nokuma komshayeli ukuze uqiniseke ukuthi ihambisana nephrojekthi yakho, kungakhathaliseki ukuthi okokusetshenziswa ekhaya noma emsebenzini.
Izingxenye ezibalulekile njengama-capacitor namajoyinti e-solder zithinta ukuthi umshayeli wakho uhlala isikhathi esingakanani. Ama-capacitor angaguga ngenxa yokushisa, futhi amalunga e-solder angaqhekeka ngaphansi kwengcindezi. Ukusebenzisa izingxenye zekhwalithi ephezulu kwehlisa lezi zingozi futhi kusiza umshayeli wakho ukuthi ahlale isikhathi eside.
Ukusetha Izidingo Zokokufaka Nokukhiphayo
Ukusetha izidingo zokufaka nokukhiphayo kusiza umshayeli wakho we-LED ukuthi asebenze kahle. Qala ngokuthola i-voltage ephumayo ephansi kakhulu. Kufanele ibe phezulu kune-voltage eya phambili yama-LED akho. Isibonelo, uma ama-LED akho edinga i-15V, okukhiphayo komshayeli kufanele kube kuthe xaxa.
Sebenzisa le fomula ukuthola i-voltage yokufaka:Vo + (Vf x LEDn) = Vin
Lapha, i-Vo iyi-voltage eyengeziwe, i-Vf iyi-voltage eya phambili, kanti i-LEDn iyinani lama-LED. Kuma-LED ayisithupha ane-3V ngayinye, i-voltage yokufaka kufanele okungenani ibe ngu-18V.
Qiniseka ukuthi umshayeli wakho uhlangabezana nezindinganiso. Isici samandla esingaphezu kuka-0.9 kanye nokuhlanekezelwa kwe-harmonic ngaphansi kuka-20% yonga amandla futhi kunqamule umsindo. Ukuze uthole izibani ezingacimeki, khetha izishayeli ezinokunemba okuphezulu, njenge-+/-2%, ukuze uthole ukukhanya okungaguquki.
