Umushoferi wa LED Dimmer ni iki?

Kubera ko LED isaba amashanyarazi ataziguye na voltage ntoya kugirango ikore, umushoferi wa LED agomba guhinduka kugirango agenzure umubare w'amashanyarazi yinjira muri LED.
Umushoferi wa LED nigice cyamashanyarazi agenga voltage numuyoboro uva mumashanyarazi kugirango LED ikore neza kandi neza. Umushoferi wa LED ahindura itangwa rya AC (AC) ituruka kumuyoboro uyobora amashanyarazi (DC) kuko ibikoresho byinshi byamashanyarazi bikoresha kumurongo.
LED irashobora gukorwa neza muguhindura umushoferi wa LED, ushinzwe kugenzura ingano yumuriro winjira muri LED. Iyi shoferi ya LED yihariye, rimwe na rimwe yitwa LED dimmer shoferi, ihindura urumuri rwa LED.
Nibyingenzi gusuzuma LED dimmer umushoferi yoroshye yo gukoresha mugihe ugura imwe. Umushoferi wa LED dimmer ufite ibice bibiri kumurongo (DIP) ahindura imbere bituma byoroha kubakoresha guhindura ibyasohotse, nabyo bigahindura urumuri rwa LED.
Guhuza umushoferi wa LED dimmer hamwe na Triode yo Guhindura Ibiriho (TRIAC) ibyapa byurukuta hamwe namashanyarazi nikindi kintu cyo kugenzura. Ibi byemeza ko ushobora kugenzura amashanyarazi yihuta yihuta yinjira muri LED kandi ko dimmer yawe izakora kumushinga wose ufite mubitekerezo.

Uburyo bubiri cyangwa ibishushanyo bikoreshwa nabashoferi ba LED dimmer kugirango bagenzure amashanyarazi yinjira muri LED: modulisiyo ya amplitude hamwe na pulse ubugari.

Kugabanya ingano yubuyobozi bugenda bunyura LED nintego yubugari bwa pulse, cyangwa PWM.
Umushoferi rimwe na rimwe azimya amashanyarazi kuri no kuzimya no gusubira inyuma kugira ngo agenzure ingano y’amashanyarazi akoresha LED, kabone niyo icyinjira cyinjira muri LED gikomeza guhoraho. Nkibisubizo byuku guhanahana gato cyane, itara riba ryijimye kandi rihindagurika kuburyo budasubirwaho kuburyo abantu batabona.

Kugabanya ingano yumuriro wamashanyarazi ujya muri LED bizwi nka amplitude modulation, cyangwa AM. Kumurika bimurika biva mugukoresha ingufu nke. Muburyo busa, kugabanuka kubisubizo byubushyuhe bwo hasi no kongera LED ikora. Flicker nayo ikurwaho niyi ngamba.
Ariko, uzirikane ko gukoresha ubu buryo bwo gucana bitwara akaga ko guhindura ibara rya LED risohoka, cyane cyane kurwego rwo hasi.

Kubona LED idashobora gutwara bizagufasha kubona byinshi mumatara yawe ya LED. Koresha umudendezo wo guhindura urumuri rwa LED yawe kugirango uzigame ingufu kandi ufite amatara meza murugo rwawe.
Twandikireukeneye amatara amwe ya LED hamwe na dimmer / dimmer dirver cyangwa ibindi bikoresho.
