Chii chinonzi LED Dimmer Driver?

Sezvo ma LED achida magetsi akananga uye magetsi mashoma kuti ashande, dhiraivha ye LED inofanira kugadziriswa kuti itonge huwandu hwemagetsi anopinda mu LED.
Mutyairi we LED chinhu chemagetsi chinodzora magetsi nemagetsi kubva mumagetsi kuitira kuti ma LED agone kushanda zvakachengeteka uye zvinobudirira. Mutyairi we LED anochinja alternating current (AC) supply kubva kuma mains kuenda ku direct current (DC) nekuti magetsi mazhinji anomhanya pama mains.
LED inogona kudzimwa nekuchinja LED driver, iyo inotarisira kudzora huwandu hwemagetsi anopinda mu LED. Iyi LED driver yakagadzirwa, dzimwe nguva inonzi LED dimmer driver, inochinja kupenya kwe LED.
Zvakakosha kufunga nezvekushandisa nyore kwemutyairi we LED dimmer paunenge uchitenga imwe. Mutyairi we LED dimmer ane dual in-line package (DIP) switches ari pamberi unoita kuti zvive nyore kune vashandisi kuchinja output current, izvo zvinozochinja kupenya kwe LED.
Kuenderana kwedhiraivha ye LED dimmer neTriode for Alternating Current (TRIAC) wall plates uye simba remagetsi chimwe chinhu chekutarisa. Izvi zvinovimbisa kuti unogona kudzora magetsi anomhanya achipinda mu LED uye kuti dimmer yako ichashanda chero basa rauri kufunga.

Nzira mbiri kana magadzirirwo anoshandiswa nemadhiraivha e LED dimmer kudzora magetsi anopinda mu LED: amplitude modulation uye pulse width modulation.

Kuderedza huwandu hwemagetsi anotungamira anopfuura nepakati pe LED ndicho chinangwa chekushandura pulse width modulation, kana kuti PWM.
Mutyairi anobatidza magetsi nguva nenguva uye anoadzima obva aadzosa zvakare kuti adzore huwandu hwemagetsi ari kushandisa LED, kunyangwe magetsi anopinda mu LED akaramba aripo. Nekuda kwekuchinjana uku kupfupi, chiedza chinodzikira uye chinodzima nekukurumidza zvisingaonekwe nevanhu.

Kuderedza huwandu hwemagetsi anopinda mu LED kunozivikanwa se amplitude modulation, kana kuti AM. Mwenje we dimmer unobva pakushandisa simba shoma. Saizvozvowo, kudzikira kwemagetsi kunoita kuti tembiricha dziderere uye kushanda zvakanaka kwe LED kuwedzere. Flicker inobviswawo neiyi nzira.
Zvisinei, yeuka kuti kushandisa nzira iyi yekudzima chiedza kune njodzi yekuchinja ruvara rwe LED, kunyanya padanho rakaderera.

Kuwana madhiraivha e LED anodzima chiedza kuchakubatsira kuti uwane zvakawanda kubva kumwenje yako ye LED. Shandisa rusununguko rwako rwekuchinja mwero wekupenya kwema LED ako kuti uchengetedze simba uye uve nemwenje wakasununguka mumba mako.
Taura nesuunoda mwenje we LED une dimmer/dimmer diver kana zvimwe zvinhu.
