Iyini i-LED Dimmer Driver? Amasu Okufiphala Amabili Okumele Uzazi

Ukukhanyisa kwe-light-emitting diode (LED) kungenziwa ngendlela oyifisayo kakhulu. Kodwa ngenxa yokuthi ama-LED asebenza kumanje oqondile, ukufiphalisa i-LED kungadinga ukusetshenziswa kwe Abashayeli be-dimmer be-LED, engasebenza ngezindlela ezimbili.

Iyini i-LED Dimmer Driver?

Ngenxa yokuthi ama-LED asebenza nge-voltage ephansi futhi ekhona ngqo, umuntu kufanele alawule inani likagesi ogeleza ku-LED ngokulungisa i-LED.'s umshayeli.

I-LED DIMMING DRIVER

Kokubili i-voltage ephansi kanye ne-voltage ephezulu ye-LED strip idinga umshayeli we-LED dimmer, edume kakhulu endaweni yebhizinisi ye-Electronic izofaka imichilo ye-LED, umshayeli we-LED dimmer nesilawuli, ezinye zizoba nezixhumi.

Ngenxa yokuthi umshayeli we-LED nguyena onesibopho sokulawula ugesi ogeleza ungene ku-LED, kungokushintsha le divayisi ukuthi i-LED ingacimeka. Lo mshayeli we-LED oshintshiwe, owaziwa nangokuthi umshayeli we-LED dimmer, ulungisa ukukhanya kwe-LED.

Uma usemakethe yomshayeli omuhle we-LED dimmer, it's kubalulekile ukunaka kalula ukusetshenziswa kwayo. Ukuba nomshayeli we-LED dimmer onamaswishi e-dual in-line package (DIP) ngaphambili kuvumela abasebenzisi ukuthi bashintshe kalula okukhiphayo kwamanje, ngakho-ke, ukulungisa ukukhanya kwe-LED.

Hhayi nje ngomugqa oholela ekufipheleni kuphela, nasemigqeni ye-RGB RGBW, sine-pixel driver.Controller nayo ibalulekile,i-traic,daynamic pixel kanye ne-CCT.Ikhasimende liyayithanda incane futhi isebenza ngezindlela eziningi,oh,ungakhohlwa ne-DMX contro.Isigcawu esidume kakhulu yi-KTV, iklabhu kanye nephrojekthi yokukhanyisa yangaphandle, Yebo, kuhle futhi ukulungisa isimo ekhaya.

Esinye isici okufanele sibhekwe ukuhambisana komshayeli we-LED dimmer namapuleti odonga we-Triode for Alternating Current (TRIAC) nezinto zikagesi. Lokhu kuqinisekisa ukuthi ungakwazi ukulawula inani lamandla kagesi agelezela ku-LED ngesivinini esikhulu, futhi i-dimmer yakho izosebenza kunoma iyiphi iphrojekthi ocabanga ngayo.

I-Pulse width modulation (PWM) ifaka ukufinyeza inani lamanje eliholayo elidlula ku-LED.

Eyamanje egeleza ku-LED iyafana, kodwa umshayeli uvame ukuyivula futhi ayivale futhi ukuze alawule inani lamanje lamandla e-LED. Lokhu kushintshisana okusheshayo kuholela ekukhanyeni okufiphele, nokucwayiza okungabonakali ngokushesha okukhulu ukuze iso lomuntu likwazi ukulibamba.

I-amplitude modulation (AM) ihlanganisa ukunciphisa amandla kagesi ageleza ku-LED. Ngamandla amancane kufika ukukhanya okufiphele. Ngokufanayo, nge-current ephansi iza nezinga lokushisa eliphansi nokusebenza okuphezulu kwe-LED. Le ndlela iphinde iqede ubungozi bokucwayiza.

Qaphela, nokho, le ndlela yokufiphaza ibeka engcupheni yokushintsha ukuphuma kombala we-LED, ikakhulukazi emazingeni aphansi. 

Ukuze ufunde kabanzi mayelana nokuthi izisombululo zethu zokukhanyisa nokufiphaza zingasiza kanjani iphrojekthi yakho iphumelele, sicela usithinte ukuze uthole icaphuna lomugqa wokufiphalisa nomshayeli noma eminye imininingwane oyidingayo!
