Iyini i-LED Dimmer Driver?

Njengoba ama-LED edinga amandla kagesi aqondile kanye ne-voltage ephansi ukuze asebenze, umshayeli we-LED kumele alungiswe ukuze alawule inani likagesi elingena ku-LED.
Umshayeli we-LED uyingxenye kagesi elawula i-voltage kanye nogesi ovela kugesi ukuze ama-LED akwazi ukusebenza ngokuphepha nangokuphumelelayo. Umshayeli we-LED ushintsha ugesi oshintshanayo (AC) ovela kugesi omkhulu uye kugesi oqondile (DC) ngoba iningi lamandla kagesi lisebenza kugesi omkhulu.
I-LED ingenziwa ifiphale ngokushintsha idrayivu ye-LED, ephethe ukulawula inani lamandla angena ku-LED. Lo mshayeli we-LED owenziwe ngokwezifiso, ngezinye izikhathi obizwa ngokuthi umshayeli we-LED dimmer, ushintsha ukukhanya kwe-LED.
Kubalulekile ukucabangela ukuthi kulula kangakanani ukusebenzisa umshayeli we-LED dimmer ngenkathi uthenga eyodwa. Umshayeli we-LED dimmer one-dual in-line package (DIP) switches ngaphambili wenza kube lula ngabasebenzisi ukushintsha amandla okukhipha, okushintsha ukukhanya kwe-LED.
Ukuhambisana kwe-LED dimmer driver nama-Triode for Alternating Current (TRIAC) wall plates kanye nokunikezwa kwamandla kungenye into okufanele uyihlole. Lokhu kuqinisekisa ukuthi ungakwazi ukulawula ugesi osheshayo ogeleza ungene ku-LED nokuthi i-dimmer yakho izosebenza kunoma yimuphi umsebenzi owucabangayo.

Izindlela ezimbili noma ukucushwa kusetshenziswa abashayeli be-LED dimmer ukulawula ugesi ongena ku-LED: ukuguquguquka kwe-amplitude kanye nokuguquguquka kobubanzi be-pulse.

Ukunciphisa inani lamandla ahamba phambili adlula ku-LED kuwumgomo we-pulse width modulation, noma i-PWM.
Umshayeli uvula futhi avale ugesi njalo futhi aphinde awuvule ukuze alawule inani lamandla kagesi anika amandla i-LED, noma ngabe ugesi ongena ku-LED uhlala ungashintshi. Ngenxa yalokhu kushintshana okufushane kakhulu, ukukhanya kuyafiphala futhi kukhanye ngokushesha okukhulu kangangokuthi umuntu akakuboni.

Ukunciphisa inani lamandla kagesi angena ku-LED kwaziwa ngokuthi i-amplitude modulation, noma i-AM. Ukukhanya kwe-dimmer kubangelwa ukusebenzisa amandla amancane. Ngendlela efanayo, ukwehla kwamandla kagesi kuholela emazingeni okushisa aphansi kanye nokusebenza kahle kwe-LED okwandisiwe. I-Flicker nayo iyasuswa ngaleli cebo.
Noma kunjalo, khumbula ukuthi ukusebenzisa le ndlela yokufiphaza kuhambisana nengozi yokushintsha umbala we-LED, ikakhulukazi emazingeni aphansi.

Ukuthola abashayeli be-LED abafiphazekayo kuzokusiza ukuthi uthole okuningi ekukhanyeni kwakho kwe-LED. Sebenzisa inkululeko yokushintsha amazinga okukhanya kwama-LED akho ukuze wonge amandla futhi ube nokukhanya okukhululekile kakhulu endlini yakho.
