Rashin gazawar gama gari guda uku na fitilun siginar LED da mafita

Wasu abokai suna tambayar dalilai na gama gari da hanyoyin magance fitilun siginar LED suna walƙiya, wasu kuma suna so su tambayi dalilin da yasa fitilun siginar LED ba sa haske.Me ke faruwa?A gaskiya ma, akwai kasawa guda uku na gama gari da mafita ga fitilun sigina.

Rashin gazawar gama gari guda uku na fitilun siginar LED da mafita:

Laifin gama gari shine gazawar gyarawa.Jeka birnin haske ka sayi daya ka maye gurbinsa.Gabaɗayan jagorar ba ta cika lalacewa ba.

Biyu.Abubuwan da ke haskaka hasken siginar Led:

1. Fitilar beads da ikon tafiyar da wutar lantarki ba su daidaita ba, daidaitattun beads ɗin fitila guda ɗaya na 1W na yau da kullun: 280-300 ma halin yanzu da: 3.0-3.4V ƙarfin lantarki, idan guntuwar fitilar ba ta da isasshen ƙarfi, zai haifar da tsayayyen tushen haske. al'amarin, idan na yanzu ya yi girma, beads na fitilu ba za su iya jure wa sauyawa ba.A lokuta masu tsanani, wayoyi na zinariya ko tagulla a cikin beads na iya ƙonewa, yana sa ƙullun su kasa aiki.

2. Na'urar wutar lantarki na iya lalacewa, muddin ka maye gurbinsa da wani ingantaccen wutar lantarki, ba zai kyalkyace ba.

3. Idan direban yana da aikin kariya na zafin jiki, aikin watsar da zafi na fitilun siginar LED ba zai iya cika buƙatun ba, kuma kariya ta zafin jiki na direba zai yi lumshe idan ya fara aiki.Misali, gidaje 20 w tsinkayar fitilar da aka yi amfani da ita don haɗa fitilun 30W baya yin kyakkyawan aiki na sanyaya.

4. Idan fitilu na waje kuma suna da abubuwan mamaki na stroboscopic, yana nufin cewa fitilu suna ambaliya.Sakamakon haka, idan ya lumshe ido, ba ya haske.An karye fitila da direba.Idan direba ya yi aiki mai kyau na hana ruwa, bead ɗin fitilar ya karye kuma ana iya canza tushen hasken.

Uku.Gudanar da hanyar walƙiya siginar jagora:

1. A cikin aikace-aikacen hasken wutar lantarki mara ƙarfi na kashe-kashe, babban ƙarfin wutar lantarki shine keɓewar topology.Green Dot, direban LED mai kashe layi na 8W, ya dace da ma'aunin hasken wutar lantarki na Star ƙarfi.A cikin yanayin ƙira, saboda jujjuyawar wutar lantarki ta sinusoidal murabba'in raƙuman raƙuman ruwa na mai sarrafa tashi baya ba ya samar da kuzari akai-akai don son rai na farko, da'irar mai ƙarfi mai ƙarfi na iya kunnawa da haifar da walƙiya haske.Don guje wa wannan matsala, ya zama dole a yi fitar da firikwensin kashe-kashe a kowane rabin zagaye.Sabili da haka, wajibi ne don zaɓar ƙimar ƙarfin ƙarfin da ƙimar juriya na fitilun siginar LED waɗanda ke zama kewaye.

2. A ka'ida idon dan adam yana iya gane fiskar haske a mitar 70 Hz, amma sama da haka ba zai iya ba.Sabili da haka, a aikace-aikacen hasken wuta, idan siginar bugun jini yana da ƙananan mitar mitar da ke ƙasa da 70 Hz, idon ɗan adam zai ji flicker.Tabbas, akwai abubuwa da yawa waɗanda zasu iya haifar da fitilun LED suyi ƙiftawa a cikin takamaiman aikace-aikacen.

3. Ana buƙatar masu tace Emi har ma a cikin aikace-aikacen tuƙi na jagoranci wanda ke ba da gyare-gyare mai kyau na ƙarfin wutar lantarki da kuma goyan bayan dimming na masu juyawa na SCR guda uku masu bi-directional.Matsakaicin halin yanzu da aka jawo ta matakin sauyin SCR na triterminal bidirectional yana faranta rai na inductor da capacitors a cikin tace emi.

Idan halayen haɓakawa ya sa shigar da halin yanzu ya zama ƙasa da riƙon halin yanzu na sassa na SCR mai kusurwa biyu na tasha, za a kashe kashi uku na SCR mai juyawa.Bayan ɗan gajeren jinkiri, ɓangaren juyawa na SCR na tasha uku zai sake kunnawa don faranta rai ɗaya.Ana iya maimaita wannan jerin abubuwan da suka faru sau da yawa a cikin rabin zagaye na ikon INPUT na madaidaicin LED, wanda ya haifar da firar LED mai gani.
