Thinta ukukhanya kwetafula le-LED elifiphalisayo
Isimiso se-LED dimmer
I-LED dimmer iyingxenye ebalulekile yamalambu esimanje, iwukuba ngokulungisa usayizi we-voltage yokuphakela amandla, ukulungisa ukukhanya kwezibani ze-LED. Ngokuthuthuka okuqhubekayo kanye nokuthuthukiswa kobuchwepheshe bokukhanyisa kwe-LED, izibani ze-LED seziphenduke imikhiqizo evamile emkhakheni wokukhanyisa kwangaphakathi nangaphandle, ngakho-ke ukusetshenziswa kwezibani ze-LED kubeke phambili izidingo eziphakeme. Lesi sihloko sizokwethula isimiso se-LED dimmer nokuthi sisebenza kanjani ngokuhambisana nezibani ze-LED ukuze uqonde kangcono futhi usebenzise le divayisi.
Umgomo we-LED dimmer
Umgomo we-LED dimmer ukushintsha ukukhanya kokuphumayo ngokulungisa i-voltage ye-DC yesibani yesibani. Njengoba isibani se-LED siwumthombo wokukhanya wamanje osebenza ngamandla, kuyadingeka ukushintsha i-voltage yamandla akhona akhona ngesikhathi sokusetshenziswa ukulawula ukukhanya komthombo wokukhanya we-LED.
Umjikelezo weIzibani ze-LEDihlanganisa izingxenye ezintathu eziyinhloko, okungukuthi ukunikezwa kwamandla, umthombo wamanje ongashintshi kanye nomthombo wokukhanya we-LED ngokwawo. Ukunikezwa kwamandla kunikeza i-voltage ehambisanayo yokushayela umthombo wokukhanya we-LED, kuyilapho umthombo wamanje oqhubekayo uqinisekisa ukuzinza komthombo wokukhanya we-LED ngokugcina okwamanje kugeleza ku-LED kungashintshiwe. Ngakho-ke, umsebenzi oyinhloko we-dimmer ukulungisa amandla kagesi, okuthinta ukukhanya komthombo wokukhanya we-LED. I-Dimmer ngokuvamile isebenzisa izindlela ezintathu zokufinyelela ukulawulwa kwamandla kagesi we-LED: ukuguquguquka kwe-PWM, ukuguquguquka kwamandla kagesi kanye nokuguquguquka kwamanje okungaguquki.
1. Ukushintshashintsha kwe-PWM
I-PWM modulation ingenye yezindlela ezivame ukusetshenziswa kakhulu zokulawula ukukhanya kwe-LED. Le modi yokulungisa ishintsha i-voltage yokuphakela amandla ngefrikhwensi ethile futhi ilawula isilinganiso somsebenzi we-voltage yokuphakela amandla kumjikelezo ngamunye, ngaleyo ndlela ithinte ukukhanya kwesibani se-LED. Ukufiphalisa okunamandla kungafinyelelwa ngokushintshashintsha kwe-PWM, kanye nokuhlangabezana nezidingo zokukhanyisa ezihlukene.
2. Imodi yokusebenza ngokubambisana phakathiIsibani se-LED nesibani se-LED
Imodi yokusebenza ngokubambisana phakathi kwe-LED dimmer nokukhanya kwe-LED iwukubona ukulungiswa kokukhanya kokukhanya kwe-LED ngokusebenzisana. Okulandelayo isingeniso esifushane sokusebenzelana phakathi kwe-LED dimmer nesibani se-LED.
1. Ukushintshashintsha kwe-PWM
Kumodi yokushintshashintsha ye-PWM, ukukhanya kokukhanya kwe-LED kulawulwa ngokulungisa umjikelezo womsebenzi wevolthi yokuphakelwa kwamandla. I-dimmer idlulisela isignali yokulungisa ekukhanyeni kwe-LED, futhi ukukhanya kwe-LED kukhipha ukukhanya okuhlukile ngokuya ngokugqama okuhlukile kwesiginali yokulungisa. Isignali yokulungisa phakathi kwakho kokubili ngokuvamile isekelwe kusignali yedijithali, ekwazi ukubona isilawuli kude kanye nokufiphala.
2. Ukuguqulwa kwamandla kagesi
Kumodi yokuguqula i-voltage, i-LED dimmer ilawula isibani se-LED ngokushayela ukuphuma kwamandla esibani se-LED.
Ilambu Ledeskithophu Le-LED Elishajwa kabusha—Umthunzi Owenziwe Ngayo
INCAZELO EMFUSHANE:
I-Wonled Pleated Shade, eshajwa kabushaisibani sedeski. Engeza ukuthinta kobuhle kunoma yisiphi isikhala ngalesi sibani esiyingqayizivele esinomthunzi owenziwe ngesitayela futhi ohlukahlukene. Ngebhethri layo elakhelwe ngaphakathi eliphinde lishajwe, ungajabulela ukuphathekaukukhanyisa okungenantambongaphandle kokuhlupheka kwezintambo. I-shades egoqayo ihlanganisa ukusebenza, ubuhle kanye nokulula, okwenza kube yi-l epheleleikhambi lokukhanyisa fnoma izindlela zokuphila zesimanje.
