Ibibi byo gucana

Kuva amatara yinjira mugihe cyamatara ya fluorescent, amatara aherekejwe n'amatara yagiye yuzuza ibidukikije. Ukurikije ihame rimurika ryamatara ya fluorescent, ikibazo cya flicker nticyakemutse neza. Uyu munsi, twinjiye mugihe cyo kumurika LED, ariko ikibazo cyo gucana urumuri kiracyahari.

Ni iki gihindagurika

Flicker ni ihinduka ryumucyo cyangwa umucyo mugihe runaka. Amatara yo kumurika aboneka mubikorwa byinshi byo kumurika, harimo kurasa gahoro kuri TV, kumurika umuhanda, imirima itandukanye yumucyo rusange hamwe n’aho ukorera ukoresheje imashini zizunguruka vuba. Flicker izagira ingaruka kubuzima bwabantu, kandi urugero rwingaruka ziterwa ninshuro za flicker hamwe no kwiyumvisha umuntu kuri flicker. Umuvuduko mwinshi wa flicker ntabwo uzagira ingaruka zikomeye kumubiri wumuntu, ariko flicker nkeya iri munsi ya Hz 120 biroroshye kubangamira ubuzima bwabantu.

Imikorere yo gupima amaso yumuntu yunvikana kuri flicker

Ibibi byo gucana

Inkomoko yumucyo ifitanye isano rya hafi na migraine, kubabara umutwe, autism, umunaniro wamaso, kutabona neza nizindi ndwara zifata ubwonko. Ubushakashatsi bwerekanye ko inshuro nke, intera ya 3-70Hz yumucyo utanga urumuri rushobora gutera igicuri gifotora kubantu bamwe bumva; 100Hz flicker frequency yagaragaye kugirango itere umutwe na migraine; 120Hz itanga urumuri rushobora kugira ingaruka kumyumvire yabantu, nko kurambirwa no guhangayika. Kwibeshya kugaragara biterwa n'ingaruka za flicker hamwe no gukanika imashini ni bibi cyane mubikorwa byinganda. Kubwibyo, gupima neza no gusuzuma ibimenyetso biranga ibicuruzwa bimurika bifitanye isano itaziguye nubuzima bwabantu, nikibazo cyihutirwa gukemurwa.

Impamvu zitera

Impamvu zitera amatara ya LED ntabwo zirimo ibintu bitanga amashanyarazi gusa, ahubwo nibintu byerekana imikorere ya tekiniki yumucyo hamwe nigishushanyo mbonera kidafite ishingiro. Umuyoboro wa Ripple nimwe mumpamvu zingenzi zitera guhindagurika mumashanyarazi yamatara menshi. Umuyoboro wa Ripple ni AC igizwe na nyuma yo gukosorwa no kuyungurura. Umuyoboro wa Ripple urenze kuri DC kandi ufite imirongo myinshi n'imirongo. Ibigize AC bituma imbaraga za LED module ihindagurika, nayo igahindura umucyo. Ingano ninshuro za AC zirenze urugero nibintu byingenzi bya flicker.

Igishushanyo cyo gusobanura indangagaciro na flicker

Nigute ushobora gukuraho flicker

Usibye umurimo wo gukuraho umwijima no kumurikira ibidukikije, itara rigomba kuzirikana imikorere yubuzima bwibicuruzwa. Kugirira nabi abantu ni igice cyimikorere yamatara atagomba kwirengagizwa.

Bitewe no gukosora amashanyarazi yatanzwe (50Hz mubipimo byuburayi), inshuro zumuvuduko mwinshi mugice kinini cya disiki ya LED ikubye kabiri amashanyarazi, ni hafi 100Hz. Byongeye kandi, ugereranije numucyo gakondo, LED irashobora guhita ihindura imikorere ikora mumucyo. Kugirango ugere kumucyo usohoka nta flicker ishoboka, umushoferi wo murwego rwohejuru wa LED hamwe no guhuza abashoferi, dimmer na LED module ni ngombwa. Ishusho ikurikira nuburyo busanzwe bwo gusuzuma igikoresho cyo kugenzura ukoresheje "ibisohoka muri ripple" cyangwa "AC superimposed AC". Mubisanzwe, agaciro kerekanwe ni 100Hz. Hasi agaciro, niko ibyago byo guhindagurika.

IEEE Yasabwe Amashusho yo Guhindura Ibiri muri LED-Yaka cyane yo kugabanya ingaruka zubuzima kubareba

Amatara ya LED ya Wellway hamwe na lghtings, yaba amatara adafite amazi, amatara yinyuguti, panne hamwe namatara adakoresha umukungugu, harimo moderi yibanze hamwe nuburyo bwo gutabaza byihutirwa, byose bimenya imikorere nta guhindagurika. Amashanyarazi yo mu rwego rwohejuru akoreshwa n’itara arashobora kugabanya ibisohoka kandi akamenya guhuza neza nibigize itara.

(Amashusho amwe ava kuri enterineti. Niba hari ihohoterwa, nyamuneka twandikire uhite uyisiba ako kanya)
