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.

Ayiphelelanga nje ekudimeni kwe-LED strips, nakwi-RGB RGBW strips, sine-pixel driver.Controller nayo ibalulekile, i-traic, i-pixel ye-daynamic kunye ne-CCT.Umthengi uyayithanda incinci kwaye isebenza ngezinto ezininzi, oh, ungalibali i-DMX contro nayo.Eyona ndawo idumileyo yiKTV, iklabhu kunye neprojekthi yokukhanyisa yaNgaphandle, 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!
