Gukoraho urumuri rwa LED urumuri
Ihame rya LED dimmer
LED dimmer nigice cyingenzi cyamatara agezweho, ni muguhindura ingano yumuriro wamashanyarazi, kugirango uhindure urumuri rwamatara ya LED. Hamwe niterambere ridahwema no kunoza ikoranabuhanga rya LED, amatara ya LED yabaye ibicuruzwa byingenzi mubijyanye no kumurika mu nzu no hanze, bityo ikoreshwa rya dimimeri LED ryashyize imbere ibisabwa byinshi. Iyi ngingo izerekana ihame rya LED dimmer nuburyo ikora ifatanije namatara ya LED kugirango wumve neza kandi ukoreshe iki gikoresho.
Ihame rya LED dimmer
Ihame rya LED dimmer nuguhindura urumuri rwibisohoka muguhindura amashanyarazi ya DC yumuriro wamatara. Kubera ko itara rya LED ari isoko yumucyo itaziguye, birakenewe guhindura voltage yumuriro wamashanyarazi mugihe cyo gukoresha kugirango ugenzure urumuri rwumucyo wa LED.
Umuzunguruko waAmataraikubiyemo ibice bitatu byingenzi, aribyo gutanga amashanyarazi, isoko ihoraho hamwe na LED yumucyo ubwayo. Amashanyarazi atanga voltage ijyanye no gutwara urumuri rwa LED, mugihe isoko ihoraho itanga ituze ryumucyo urumuri rwa LED mugukomeza amashanyarazi anyuze muri LED idahindutse. Kubwibyo, umurimo wingenzi wa dimmer nuguhindura amashanyarazi yumuriro, bigira ingaruka kumucyo wumucyo wa LED. Dimmer muri rusange binyuze muburyo butatu kugirango ugere kuri LED itanga amashanyarazi: modulisiyo ya PWM, modulisiyo ya voltage hamwe na modulasiyo ihoraho.
1. Guhindura PWM
Guhindura PWM ni bumwe mu buryo bukoreshwa cyane bwa LED dimmer. Ubu buryo bwo guhindura ibintu buhindura amashanyarazi kumashanyarazi kumurongo runaka kandi bugenzura igipimo cyakazi cyumuriro wamashanyarazi muri buri cyiciro, bityo bikagira ingaruka kumurika ryitara rya LED. Dynamic dimming irashobora kugerwaho binyuze muri modulisiyo ya PWM, kimwe no guhuza amatara atandukanye.
2. Uburyo bwo gukora bwa koperative hagatiLED dimmer hamwe n'amatara ya LED
Uburyo bwa koperative ikora hagati ya LED dimmer nu mucyo wa LED ni ukumenya ihinduka ryumucyo urumuri rwa LED binyuze mubikorwa. Ibikurikira nintangiriro ngufi yimikoranire hagati ya LED dimmer nu mucyo wa LED.
1. Guhindura PWM
Muburyo bwo guhindura moderi ya PWM, urumuri rwurumuri rwa LED rugenzurwa no guhindura urwego rwinshingano zumuriro w'amashanyarazi. Dimmer yohereza ibimenyetso byo guhinduranya urumuri rwa LED, kandi urumuri rwa LED rusohora urumuri rutandukanye ukurikije urumuri rutandukanye rwikimenyetso. Ikimenyetso cyo guhinduranya hagati yibi byombi gishingiye ku kimenyetso cya digitale, gishobora kumenya kugenzura kure no kugabanuka.
2. Guhindura amashanyarazi
Muburyo bwo guhinduranya imbaraga za voltage, LED dimmer igenzura itara rya LED mugutwara ingufu zumucyo wa LED.
Amatara yaka LED Amatara-Igicucu
GUSOBANURA Gufi:
Wonled Pleated Shade, yishyurwaitara ryameza. Ongeraho gukoraho elegance kumwanya uwo ariwo wose hamwe niri tara ridasanzwe ryerekana igicucu cyiza kandi gihindagurika. Hamwe na bateri yubatswe yuzuye, urashobora kwishimira portableitara ridafiteudafite ikibazo cyinsinga. Igicucu kizinga gihuza imikorere, ubwiza nuburyo bworoshye, bigatuma biba byiza lgukemura fcyangwa imibereho igezweho.
