Ngaba ukhe waqaphela ukuba ngenye imini, umbala wokukhanya ukhupha Ngaba ukhe waqaphela ukuba ngenye imini,umbala wokukhanya okhutshwa sisibane sakho watshintsha ngesiquphe?
Lo ngumba oqhelekileyo odibana nabantu abaninzi.Njengabenzi bemveliso ye-LED, sihlala sibuzwa ngale ngxaki.
Lo mcimbi waziwa ngokubaukutenxa kombalaokanye ukugcinwa kombala kunye ne-chromaticity shift, eye yaba ngumba wexesha elide kwishishini lokukhanyisa.
Ukutenxa kombala akuyodwa kwimithombo yokukhanya ye-LED.Enyanisweni, inokwenzeka kuwo nawuphi na umthombo wokukhanya osebenzisa i-phosphors kunye / okanye imixube yegesi ukuvelisa ukukhanya okumhlophe, kubandakanywa izibane ze-fluorescent kunye nezibane ze-metal halide.
Ixesha elide, ukuphambuka kombala kuye kwaba yingxaki ephazamisa umbaneKangangexesha elide, ukuphambuka kombala kuye kwaba yingxaki ephazamisa ukukhanya kombane kunye nobuchwepheshe obuphelelwe lixesha obufana nezibane ze-metal halide kunye nezibane ze-fluorescent.
Kuqhelekile ukubona umqolo wezinto ezikhanyayo apho isixhobo ngasinye sivelisa imibala eyahlukileyo kancinane emva kokubaleka kumakhulu ambalwa eeyure.
Kule nqaku, siya kukuxelela malunga nezizathu zokuphambuka kombala kwizibane ze-LED kunye neendlela ezilula zokuziphepha.
Izinto ezibangela ukutenxa koMbala kwizibane ze-LED:
- Izibane ze-LED
- Inkqubo yokulawula kunye nomqhubi we-IC
- Inkqubo yeMveliso
- Ukusetyenziswa ngokungafanelekanga
Izibane ze-LED
(1) Iiparamitha ze-chip ezingahambelaniyo
Ukuba iiparamitha ze-chip yesibane se-LED azihambelani, kunokubangela ukungafani kombala kunye nokukhanya kokukhanya okukhutshiweyo.
(2) Iziphene kwizinto ze-encapsulant
Ukuba kukho iziphene kwizinto ze-encapsulant zesibane se-LED, kunokuchaphazela umphumo wokukhanyisa izibane zesibane, okukhokelela ekuphambukeni kombala kwisibane se-LED.
(3) Iimpazamo kwi-die bonding position
Ngexesha lokuveliswa kwezibane ze-LED, ukuba kukho iimpazamo ekubekweni kwe-die bonding, kunokuchaphazela ukuhanjiswa kwemitha yokukhanya, okubangela izibane ezinemibala eyahlukeneyo ekhutshwe sisibane se-LED.
(4) Iimpazamo kwinkqubo yokwahlula umbala
Kwinkqubo yokwahlula umbala, ukuba kukho iimpazamo, kunokubangela ukusabalalisa kombala ongalinganiyo wokukhanya okukhutshwa sisibane se-LED, okubangela ukuphambuka kombala.
(5) Imiba yokubonelela ngombane
Ngenxa yothintelo lobugcisa, abanye abavelisi banokuqikelela okanye bajongele phantsi unikezelo lwamandla kunye nokusetyenziswa kwamandla kwiimveliso zabo, okukhokelela ekuguquguqukeni okulambathayo kweemveliso eziveliswayo kunikezelo lombane.Oku kunokukhokelela kunikezelo lwamandla olungalinganiyo kwaye kubangele ukutenxa kombala.
(6) Umba wolungiselelo lwesibane
Ngaphambi kokuba ugcwalise imodyuli ye-LED ngeglue, ukuba umsebenzi wokulungelelaniswa uyenziwa, unokwenza ukucwangciswa kobuhlalu besibane ngokulandelelana.Nangona kunjalo, kunokubangela ukungalungelelani kakuhle kwamaso wesibane kunye nokuhanjiswa kombala ongalinganiyo, okukhokelela ekuphambukeni kombala kwimodyuli.
Inkqubo yokulawula kunye nomqhubi we-IC
Ukuba uyilo, uphuhliso, uvavanyo, kunye nezakhono zemveliso yenkqubo yokulawula okanye umqhubi we-IC awanelanga, kunokubangela utshintsho kumbala weskrini se-LED.
Inkqubo yeMveliso
Ngokomzekelo, imiba yomgangatho we-welding kunye neenkqubo zokuhlanganisana ezimbi zonke zinokukhokelela ekuphambukeni kombala kwiimodyuli zokubonisa i-LED.
Ukusetyenziswa ngokungafanelekanga
Xa izibane ze-LED zisebenza, iichips ze-LED zihlala zivelisa ubushushu.Izibane ezininzi ze-LED zifakwe kwisixhobo esincinci esisisigxina.Ukuba izibane zisebenza iiyure ezingama-24 ngosuku ngaphezu konyaka, ukusetyenziswa ngokugqithisileyo kunokuchaphazela ubushushu bombala wetshiphu.
Ukuphepha njani ukutenxa kombala we-LED?
Ukutenxa kombala yinto eqhelekileyo, kwaye sinokubonelela ngeendlela ezininzi ezilula zokuyinqanda:
1.Khetha iimveliso ze-LED ezikumgangatho ophezulu
Ngokuthenga iimveliso zokukhanyisa i-LED kubathengisi abathembekileyo okanye abo banezatifikethi ze-CCC okanye ze-CQC, unokunciphisa kakhulu utshintsho lobushushu bombala obangelwa yimiba yomgangatho.
2.Qwalasela ukusebenzisa izibane ezikrelekrele ezinobushushu obunokutshintsha umbala
Oku kukuvumela ukuba ulungelelanise ubushushu bombala kunye nokukhanya njengoko kufuneka.Ezinye izibane ze-LED kwiimarike zikwazi ukulungelelanisa ubushushu bombala, ngokuyila isekethe, ukushisa kombala wesibane kunokutshintsha kunye nokutshintsha kokukhanya okanye kuhlala kungatshintshi nangona kukho utshintsho ekukhanyeni.
3.Kuphephe ukusebenzisa amanqanaba okukhanya aphezulu kakhulu kangangexesha elide
Ukunciphisa ukuthotywa komthombo wokukhanya.Ngoko ke, sincoma abasebenzisi ukuba bakhethe amaqondo okushisa afanelekileyo kwiimeko ezifanelekileyo, ukuba abaqinisekanga malunga nendlela yokukhetha ubushushu bombala, banokubhekisela kumcimbi wangaphambili (Yintoni iqondo lobushushu elilungileyo lokukhanya kwe-LED).
4.Hlola rhoqo kwaye ulondoloze izibane ze-LED ukuqinisekisa ukusebenza kwazo ngokufanelekileyo.
Isishwankathelo
Sikholelwa ukuba uzuze ukuqonda ngokubanzi izizathu zokuphambuka kombala kwizibane ze-LED kunye neendlela ezilula zokuziphepha.
Ukuba ujonge ukuthenga izibane ze-LED ezikumgangatho ophezulu, iChiswear ihlala ikulungele ukukunceda.Cwangcisa ukubonisana kwakho ngezibane zasimahla namhlanje.
