Yintoni i-LED Dimmer Driver? Iindlela ezimbini zokuDimming oFumana Uzazi

Ukukhanya kwe-diode emitting diode (i-LED) kunokwenziwa ngokwezifiso. Kodwa ngenxa yokuba ii-LED zisebenza ngokuthe ngqo, ukufiphala kwe-LED kuya kufuna ukusetyenziswa kwe Abaqhubi be-LED dimmer, enokusebenza ngeendlela ezimbini.

Yintoni i-LED Dimmer Driver?

Ngenxa yokuba ii-LED zisebenza kumbane ophantsi kwaye ngokuthe ngqo, umntu kufuneka alawule ubungakanani bombane ogeleza kwi-LED ngokulungelelanisa i-LED.'s umqhubi.

Zombini i-voltage ephantsi kunye ne-high voltage strip ye-LED idinga umqhubi we-LED dimmer, ethandwa kakhulu kwiqonga loshishino lwe-Electronic iya kubandakanya imichilo ye-LED, umqhubi we-LED dimmer kunye nomlawuli, ezinye ziya kuba nezihlanganisi.

Ngenxa yokuba umqhubi we-LED nguye ojongene nokulawula umbane ogeleza kwi-LED, ngokuguqula esi sixhobo ukuba i-LED inokucima. Lo mqhubi we-LED olungisiweyo, owaziwa ngokuba ngumqhubi we-LED dimmer, ulungelelanisa ukukhanya kwe-LED.

Xa kwimarike umqhubi LED dimmer elungileyo, it's kubalulekile ukunikela ingqalelo lula yayo ukusetyenziswa. Ukuba nomqhubi we-LED we-dimmer ene-double in-line package (DIP) etshintshayo ngaphambili ivumela abasebenzisi ukuba batshintshe ngokulula imveliso yangoku, ngoko ke, ukulungelelanisa ukukhanya kwe-LED.

Ayipheleli kwimigca ekhokelela eluzizi, nakwizintlu zeRGB RGBW, sinepixel driver.Controller nayo ibalulekile, traic,daynamic pixel kunye neCCT.Umthengi uyayithanda incinci kwaye inemisebenzi emininzi,oh,ungalibali iDMX contro nayo.Eyona ndawo idumileyo yiKTV,iklabhu kunye neprojekthi yokukhanyisa yaNgaphandle,Kakade kunjalo, kulunge kakhulu ukulungisa umoya ekhaya.

Enye into ekufuneka uyijonge kukuhambelana komqhubi we-LED dimmer kunye ne-Triode ye-Alternating Current (TRIAC) iipleyiti zodonga kunye nombane. Oku kuqinisekisa ukuba unokulawula isixa sombane oqukuqelayo kwi-LED ngesantya esiphezulu, kwaye i-dimmer yakho iya kukhonza nayiphi na iprojekthi onayo engqondweni.

Ukumodareyitha kobubanzi be-Pulse (PWM) kubandakanya ukucutha ubungakanani bangoku obuhamba phambili kwi-LED.

Ikhoyo ngoku egeleza kwi-LED iyafana, kodwa umqhubi uhlala ejika i-current and off and on again ukuze alawule ubungakanani be-LED yangoku. Olu tshintshiselwano lukhawulezayo ngokwenene lukhokelela ekukhanyisweni koluzizi, kunye nenkangeleko engaqondakaliyo ekhawulezayo ukuba ingabanjwa liso lomntu.

I-Amplitude modulation (AM) ibandakanya ukunciphisa umbane ohambayo kwi-LED. Ngamandla amancinci kufika ukukhanya okuluzizi. Ngokukwanjalo, ngokusezantsi kwangoku kuza ubushushu obuphantsi kunye nokusebenza okuphezulu kwe-LED. Le ndlela iphinda isuse umngcipheko we-flicker.

Qaphela, nangona kunjalo, le ndlela yokuncipha ibeka umngcipheko wokuguqula umbala we-LED, ngakumbi kumanqanaba aphantsi. 

Ukuze ufunde ngakumbi malunga nokuba ukukhanya kwethu kunye nezisombululo zobumnyama ezinokuthi zincede njani iprojekthi yakho iphumelele, nceda uqhagamshelane nathi malunga nesicatshulwa somcu we-dimming kunye nomqhubi okanye ezinye iinkcukacha ozifunayo!
