Umushoferi wa LED Dimmer ni iki?

Kubera ko LED zisaba umuriro utaziguye n'amashanyarazi make kugira ngo zikore, igikoresho gitwara urumuri (driver) cya LED kigomba guhindurwa kugira ngo kigenzure ingano y'amashanyarazi yinjira muri LED.
Umushoferi wa LED ni igice cy'amashanyarazi kigenzura voltage n'amashanyarazi biva mu muyoboro w'amashanyarazi kugira ngo LED zikore neza kandi mu mutekano. Umushoferi wa LED ahindura umuyoboro wa alternating current (AC) uva mu muyoboro w'amashanyarazi ukajya mu muyoboro w'amashanyarazi (DC) kuko ingufu nyinshi zikorera ku muyoboro w'amashanyarazi.
LED ishobora guhindurwamo umushoferi wa LED, ushinzwe kugenzura ingano y'amashanyarazi yinjira muri LED. Iyi shoferi ya LED yihariye, rimwe na rimwe yitwa umushoferi wa LED dimmer, ihindura ubwiza bwa LED.
Ni ngombwa kuzirikana uburyo bworoshye bwo gukoresha umushoferi wa LED dimmer mu gihe ugura. Umushoferi wa LED dimmer ufite paki ebyiri (DIP) imbere yorohereza abakoresha guhindura amashanyarazi asohoka, ibyo bigatuma urumuri rwa LED ruhinduka.
Uburyo umushoferi wa LED dimmer akoresha Triode for Alternating Current (TRIAC) hamwe n'amashanyarazi ni ikindi kintu ugomba kugenzura. Ibi byemeza ko ushobora kugenzura umuvuduko w'amashanyarazi wihuta winjira muri LED kandi ko dimmer yawe izakorera umushinga uwo ari wo wose wifuza.

Uburyo bubiri cyangwa imiterere ikoreshwa n'abashoferi ba LED ba dimmer kugira ngo bagenzure amashanyarazi yinjira muri LED: modulation ya amplitude na modulation ya pulse width.

Intego ya PWM ni ukugabanya ingano y'umuyoboro w'amashanyarazi unyura muri LED.
Umushoferi afungura, agafunga, agasubiza inyuma kugira ngo agenzure ingano y'amashanyarazi akoresha LED, nubwo umuriro winjira muri LED waba uhoraho. Kubera uku guhererekanya igihe gito cyane, urumuri rugenda rugabanuka kandi rukazima vuba cyane ku buryo umuntu atabona.

Kugabanya ingano y'amashanyarazi yinjira muri LED bizwi nka amplitude modulation, cyangwa AM. Amatara agabanya urumuri aturuka ku gukoresha ingufu nke. Mu buryo nk'ubwo, kugabanuka k'amashanyarazi bigabanya ubushyuhe kandi bigatuma imikorere ya LED irushaho kwiyongera. Flicker nayo ikurwaho hakoreshejwe iyi ngamba.
Ariko, ibuka ko gukoresha ubu buryo bwo gupima urumuri bigira ingaruka mbi zo guhindura ibara ry'urumuri rwa LED, cyane cyane ku rwego rwo hasi.

Kugura amatara ya LED agabanya urumuri bizagufasha kubona umusaruro mwinshi mu matara yawe ya LED. Koresha neza ubwisanzure bwo guhindura urugero rw'urumuri rwa LED zawe kugira ngo uzigame ingufu kandi ugire urumuri rwiza mu nzu yawe.
TwandikireEse ukeneye amatara ya LED afite dimmer/dimmer diver cyangwa ibindi bikoresho?
