Chukumisa ukukhanya kwetafile ye-LED
Umgaqo we-LED dimmer
Ukukhanya kwe-LED yinxalenye ebalulekileyo yezibane zanamhlanje, kungokulungelelanisa ubungakanani bombane wombane wombane, ukulungelelanisa ukukhanya kwezibane ze-LED.Ngophuhliso oluqhubekayo kunye nokuphuculwa kweteknoloji yokukhanyisa i-LED, izibane ze-LED ziye zaba yimveliso eqhelekileyo kwintsimi yokukhanya kwangaphakathi nangaphandle, ngoko ke ukusetyenziswa kwe-LED dimmers kuye kwabeka iimfuno eziphezulu.Eli nqaku liza kwazisa umgaqo we-LED dimmer kunye nendlela esebenza ngayo ngokubambisana nezibane ze-LED ukuqonda ngcono nokusebenzisa esi sixhobo.
Umgaqo we-LED dimmer
Umgaqo we-LED dimmer kukutshintsha ukukhanya kwemveliso ngokuhlengahlengisa i-DC amandla ombane wesibane.Ekubeni isibane se-LED singumthombo wokukhanya onikwe amandla ngoku ngokuthe ngqo, kuyimfuneko ukutshintsha i-voltage yonikezelo lwamandla lwangoku ngokuthe ngqo ngexesha lokusetyenziswa ukulawula ukukhanya komthombo wokukhanya kwe-LED.
Isekethe yeIzibane ze-LEDibandakanya amacandelo amathathu angundoqo, oko kukuthi unikezelo lwamandla, umthombo okhoyo ngoku kunye nomthombo wokukhanya we-LED ngokwawo.Ukunikezelwa kwamandla kunika i-voltage ehambelanayo yokuqhuba umthombo wokukhanya kwe-LED, ngelixa umthombo oqhubekayo wangoku uqinisekisa ukuzinza komthombo wokukhanya kwe-LED ngokugcina i-current flowing kwi-LED ingatshintshi.Ngoko ke, umsebenzi oyintloko we-dimmer kukulungelelanisa umbane wombane, ochaphazela ukukhanya komthombo wokukhanya kwe-LED.I-Dimmer ngokubanzi ngeendlela ezintathu zokufezekisa ukulawulwa kwamandla ombane we-LED: ukumodareyitha kwe-PWM, ukumodareyithwa kombane kunye nokumodareyitha okukhoyo ngoku rhoqo.
1. Ukumodareyitha kwePWM
Ukumodareyitha kwe-PWM yenye yezona ndlela zixhaphakileyo zolawulo lwe-LED dimmer.Le ndlela yokulungelelanisa itshintsha amandla ombane ombane kwi-frequency ethile kwaye ilawula umlinganiselo womsebenzi wombane wobonelelo lwamandla kumjikelo ngamnye, ngaloo ndlela ichaphazela ukuqaqamba kwesibane se-LED.Ubumnyama obunamandla bunokufikelelwa ngokumodareyitha kwePWM, kunye nokuhlangabezana neemfuno ezahlukeneyo zokukhanyisa.
2. Indlela yokusebenza yentsebenziswano phakathiUkukhanya kwe-LED kunye nokukhanya kwe-LED
Imowudi yokusebenza ngokubambisana phakathi kwe-LED dimmer kunye nokukhanya kwe-LED kukuqonda ukulungiswa kokukhanya kokukhanya kwe-LED ngokusebenzisana.Oku kulandelayo sisingeniso esifutshane kwintsebenziswano phakathi kwe-LED dimmer kunye nokukhanya kwe-LED.
1. Ukumodareyitha kwePWM
Kwimowudi yokumodareyitha ye-PWM, ukukhanya kokukhanya kwe-LED kulawulwa ngokulungelelanisa umjikelo womsebenzi wombane wobonelelo lwamandla.I-dimmer idlulisela isignali yokulungelelanisa kwisibane se-LED, kwaye ukukhanya kwe-LED kuvelisa ukukhanya okwahlukileyo ngokokukhanya okwahlukileyo kwesiginali yohlengahlengiso.Isiginali yohlengahlengiso phakathi kwezi zimbini ihlala isekwe kwisiginali yedijithali, enokuqonda ulawulo olukude kunye nobumnyama.
2. Ukuguqulwa kombane
Kwimowudi yokumodareyitha kombane, i-LED dimmer ilawula isibane se-LED ngokuqhuba ukuphuma kwamandla kwisibane se-LED.
Isibane seDesika eHlaziywayo ye-LED-Pleated Shade
INKCAZELO FUTSHANE:
Wonled Pleated Shade, a retshargeableisibane sedesika.Yongeza ukubamba ubuhle kuyo nayiphi na indawo ngesi sibane sikhethekileyo sinomthunzi owenziwe ngesitayile noguquguqukayo.Ngebhetri yayo eyakhelwe-ngaphakathi etshajwayo, ungonwabela ukuphathekaukukhanya okungenazintambongaphandle kobunzima beentambo.I-shades yokugoqa idibanisa ukusebenza, i-aesthetics kunye nokulula, okwenza kube yi-l epheleleyoisisombululo sokukhanyisa fokanye iindlela zokuphila zanamhlanje.
