Iyini i-LED Dimmer Driver? Izindlela Ezimbili Zokufiphaza Okudingeka Uzazi

Ukukhanya kwe-light-emitting diode (LED) kungenziwa ngokwezifiso kakhulu. Kodwa ngenxa yokuthi ama-LED asebenza ku-direct current, ukufiphaza i-LED kungadinga ukusetshenziswa kwe- Abashayeli be-LED dimmer, okungasebenza ngezindlela ezimbili.

Iyini i-LED Dimmer Driver?

Ngenxa yokuthi ama-LED asebenza nge-voltage ephansi kanye ne-direct current, umuntu kufanele alawule inani likagesi eligeleza ku-LED ngokulungisa i-LED.'umshayeli.

Kokubili i-LED strip ene-voltage ephansi kanye ne-high voltage idinga umshayeli we-LED dimmer, odumile kakhulu epulatifomu yebhizinisi le-elekthronikhi ifaka phakathi imichilo ye-LED, umshayeli we-LED dimmer kanye nesilawuli, ezinye zizoba nezixhumi. Ngakho-ke ukuze kube ne-LED strip efiphazayo, kuyadingeka.

Ngenxa yokuthi umshayeli we-LED nguyena ophethe ukulawula ugesi ogeleza ungene ku-LED, kungukushintsha le divayisi lapho i-LED ingafinyezeka khona. Lo mshayeli we-LED oguquliwe, owaziwa nangokuthi umshayeli we-LED dimmer, ulungisa ukukhanya kwe-LED.

Uma ufuna i-LED dimmer driver enhle, iyatholakala'Kubalulekile ukunaka ukuthi kulula kangakanani ukuyisebenzisa. Ukuba nomshayeli we-LED dimmer onezinkinobho ezimbili zephakheji (i-DIP) ngaphambili kuvumela abasebenzisi ukuthi bashintshe kalula amandla okukhipha, ngakho-ke, balungise ukukhanya kwe-LED.

Akukhona nje kuphela ukuthi i-LED strip iyafiphala, kodwa futhi nemicu ye-RGB RGBW, sinomshayeli we-pixel. Isilawuli sibalulekile futhi, sibalulekile, sibalulekile, sibalulekile, futhi sibalulekile. Ikhasimende liyayithanda incane futhi isebenza ngezindlela eziningi, ungakhohlwa nokulawula kwe-DMX. Indawo ethandwa kakhulu yi-KTV, iklabhu kanye nephrojekthi yokukhanyisa yangaphandle, Yebo, kuhle futhi ukulungisa isimo ekhaya.

Esinye isici okufanele usiqaphele ukuhambisana kwe-LED dimmer driver nama-wall plate e-Triode for Alternating Current (TRIAC) kanye nezinsiza zikagesi. Lokhu kuqinisekisa ukuthi ungakwazi ukulawula inani lamandla kagesi ageleza ku-LED ngesivinini esikhulu, futhi i-dimmer yakho izokhonza noma yimuphi umsebenzi owucabangayo.

Ukuguqulwa kobubanzi be-pulse (PWM) kuhilela ukunciphisa inani lamandla ahamba phambili adlula ku-LED.

Ugesi ogeleza ungene ku-LED uyafana, kodwa umshayeli uvula futhi avale ugesi njalo ukuze alawule inani logesi onika amandla i-LED. Lokhu kushintshana okusheshayo kuphumela ekukhanyeni okufiphele, okunokukhanya okungabonakali okusheshayo kakhulu ukuba iso lomuntu lingakubamba.

Ukuguqulwa kwe-Amplitude (AM) kuhilela ukunciphisa ugesi ogeleza ungene ku-LED. Ngamandla amancane kuza ukukhanya okufiphele. Ngokufanayo, ngogesi ophansi kuza izinga lokushisa eliphansi kanye nokusebenza kahle okuphezulu kwe-LED. Le ndlela futhi isusa ingozi yokufiphala.

Nokho, qaphela ukuthi le ndlela yokufiphaza ibeka engcupheni yokushintsha umbala ophumayo we-LED, ikakhulukazi emazingeni aphansi. 

Ukuze ufunde kabanzi ngokuthi izixazululo zethu zokukhanyisa nokufiphaza zingasiza kanjani iphrojekthi yakho iphumelele, sicela usithinte ukuze uthole isilinganiso se-dimmming strip ene-driver noma olunye ulwazi oludingayo!
