Isesengura ryumubano uri hagati yubwiza bwamatara ya LED nimbaraga zo gutwara

LED yateye imbere byihuse mubice bitandukanye byo gusaba mumyaka yashize, kubera ko idafite ibintu byuburozi, byangiza ibidukikije, bifite ubuzima burebure bwa serivisi, kandi bifite optique nziza.Mubyigisho, ubuzima bwa serivisi ya LED ni amasaha agera ku 100.000, ariko muburyo bwose bwo gusaba, bamwe mubashushanya amatara LELED ntibazi bihagije kubyerekeranye no gutwara amashanyarazi ya LED cyangwa kuyakoresha bidafite ishingiro, kandi umwanzuro ugabanya cyane ubuzima bwa serivisi yo kumurika LED ibicuruzwa.

Bitewe numwihariko wibikorwa bya LED, gutunganya no kubyaza umusaruro, ibiranga ingufu za voltage zigezweho nizikora za LED zakozwe nababikora batandukanye ndetse nabakora uruganda rumwe mugice kimwe cyibicuruzwa bifite itandukaniro rinini kubantu.Dufashe urumuri rusanzwe rwa 1W rwera LED ibisobanuro hamwe na moderi nkurugero, ukurikije ihinduka ryimihindagurikire yumuriro wa LED na voltage ikora, birasobanurwa muri make ko urumuri rwera 1W rusanzwe rukoresha imbaraga zumurimo zingana na 3.0-3.6V.Kugirango ubuzima bwa serivisi bube 1WLED, uruganda rusanzwe rwa LED rusaba ko uruganda rumurika rukoresha amashanyarazi ya 350mA kugirango utware.Iyo umuyoboro wimbere kumpande zombi za LED ugeze kuri 350mah, imbaraga zakazi zikora kumpande zombi za LED ntiziyongera cyane, ibyo bikazamura cyane imbere yimbere ya LED kugirango yongere amatara ya LED, bigatuma ubushyuhe bwibidukikije bwa LED bwinjira umurongo ugereranije, bityo byihutisha urumuri rwa LED.ibyangiritse, kugabanya ubuzima bwa serivisi ya LED.Bitewe numwihariko wa LED ikora ya voltage ikora nimpinduka zubu, amashanyarazi yo guhinduranya atwara LED aracungwa neza.

LED Drive yo guhinduranya amashanyarazi niyo shingiro ryamatara ya LED.Nubwonko bwumuntu.Kugirango ukore amatara yo mu rwego rwohejuru ya LED, uburyo bwo guhora-voltage bwo gutwara LED bigomba gutereranwa.
Kuri iki cyiciro, kubicuruzwa byoroheje bya LED byakozwe nababikora benshi (nk'uruzitiro rukingira, ibikombe by'amatara, amatara ya projection, amatara ya nyakatsi, nibindi), hitamo abarwanya, kugabanya umuvuduko wamaraso, hanyuma wongereho umuyoboro wa Zener diode Zener mumashanyarazi ya LED. sisitemu yo gutanga, kugirango uteze imbere LED Uburyo bufite ingaruka mbi, mbere ya byose, ntabwo bukora neza, bukoresha ingufu za electromagnetique nyinshi kumurwanya wamanutse, ndetse birashobora no kurenga ingufu za electronique zikoreshwa na LED, kandi ntizishobora gutwara amashanyarazi manini.Kuberako urwego ruri hejuru, imbaraga ninshi zikwirakwizwa kumurongo wamanutse, nta cyemeza ko LED itazarenga imikorere isanzwe.Mugihe utegura ibicuruzwa, guhitamo kugabanya ingufu za DC ebyiri za LED kugirango utware sisitemu yo gutanga amashanyarazi ninyungu nini yo kureka LED chromaticity.Hitamo kurwanywa, uburyo bwo kugabanya umuvuduko wamaraso kugirango usunike LED, urumuri rwa ecran ya LED ntishobora guhagarara neza.Iyo amashanyarazi yo gutanga amashanyarazi ya sisitemu yo gutanga amashanyarazi ari make, chromaticité ya LED iba yijimye, kandi iyo amashanyarazi yumuriro wa sisitemu yo gutanga amashanyarazi ari menshi, chromaticitike ya LED iba myinshi, kandi chromaticity ya LED ni muremure.Mubisanzwe, uburyo bwo kugabanya umuvuduko wamaraso ninyungu nini yo kugabanya igiciro.
