Yintoni i-LED Dimmer Driver? Iindlela ezimbini zokuDimming ekufuneka uzazi

Ukukhanya kwe-light-emitting diode (LED) kuyenzeka ngokwezifiso kakhulu. Kodwa ngenxa yokuba ii-LED zisebenza kwi-direct current, ukufiphaza i-LED kuya kufuna ukusetyenziswa kwe Abaqhubi be-LED dimmer, enokusebenza ngeendlela ezimbini.

Yintoni i-LED Dimmer Driver?

Ngenxa yokuba ii-LED zisebenzisa i-voltage ephantsi kwaye zikwi-direct current, umntu kufuneka alawule ubungakanani bombane ohamba kwi-LED ngokulungelelanisa i-LED.'umqhubi.

Zombini i-LED strip ye-voltage ephantsi kunye ne-high voltage idinga i-LED dimmer driver, ethandwa kakhulu kwi-Electronic business platform iya kubandakanya ii-LED strips, i-LED dimmer driver kunye ne-controller, ezinye ziya kuba nezihlanganisi. Ngoko ke ukuze i-LED strip ye-dimming, kuyimfuneko.

Ngenxa yokuba umqhubi we-LED nguye onoxanduva lokulawula umbane ohamba kwi-LED, kukutshintsha esi sixhobo apho i-LED inokufiphala khona. Lo mqhubi we-LED oguquliweyo, okwaziwa ngokuba ngumqhubi we-LED dimmer, ulungisa ukukhanya kwe-LED.

Xa ufuna i-LED dimmer driver elungileyo, iyasebenza.'Kubalulekile ukuba uqaphele ukuba kulula ukuyisebenzisa. Ukuba ne-LED dimmer driver ene-dual in-line package (DIP) switches ngaphambili kuvumela abasebenzisi ukuba batshintshe ngokulula i-output current, ngoko ke, balungise ukukhanya kwe-LED.

Asikuko kuphela ukufiphalisa i-LED strip, sikwanayo nemicu ye-RGB RGBW, sinayo ne-pixel driver. Isilawuli sibalulekile, sibalulekile, sine-daynamic pixel kunye ne-CCT. Umthengi uyayithanda incinci kwaye inemisebenzi emininzi, oh, ungalibali nolawulo lwe-DMX. Eyona ndawo idumileyo yi-KTV, iklabhu kunye neprojekthi yokukhanyisa yangaphandle, ewe, kulungile ukulungisa umoya ekhaya.

Enye into ekufuneka uyiqwalasele kukuhambelana kwe-LED dimmer driver kunye neeplati zodonga zeTriode for Alternating Current (TRIAC) kunye nezixhobo zombane. Oku kuqinisekisa ukuba unokulawula ubungakanani bombane ohamba kwi-LED ngesantya esiphezulu, kwaye i-dimmer yakho iya kusebenza kuyo nayiphi na iprojekthi ocinga ngayo.

Ukuguqulwa kobubanzi bepulse (PWM) kubandakanya ukunciphisa ubungakanani bombane ohamba nge-LED.

Umbane ohamba kwi-LED uyafana, kodwa umqhubi uhlala evula aze avale umbane aze awuvule kwakhona ukuze alawule ubungakanani bombane onika amandla i-LED. Olu tshintsho lukhawulezayo lubangela ukukhanya okufipheleyo, kunye nokukhanya okungabonakaliyo okukhawulezayo kangangokuba iliso lomntu alinakukwazi ukubamba.

Ukuguqulwa kwe-Amplitude (AM) kubandakanya ukunciphisa umsinga wombane ohamba kwi-LED. Xa amandla engaphantsi kuza ukukhanya okufipheleyo. Ngokufanayo, xa amandla esezantsi kuza ubushushu obuphantsi kunye nokusebenza okuphezulu kwe-LED. Le ndlela ikwasusa umngcipheko wokufiphala.

Qaphela, nangona kunjalo, le ndlela yokufiphalisa ibeka emngciphekweni ukutshintsha umbala we-LED, ingakumbi kumanqanaba aphantsi. 

Ukuze ufunde okungakumbi malunga nendlela izisombululo zethu zokukhanyisa kunye nokunciphisa ukukhanya ezinokunceda ngayo iprojekthi yakho iphumelele, nceda unxibelelane nathi ukuze ufumane isicatshulwa se-dimmming strip kunye nomqhubi okanye olunye ulwazi oluneenkcukacha olufunayo!
