1. Pakali pano/voltage magawo a ma LED oyera (zabwino ndi zobwerera)
LED yoyera imakhala ndi mawonekedwe a PN junction volt-ampere. Zamakono zimakhudza mwachindunji kuwunikira kwa LED yoyera ndi kulumikizana kwa chingwe cha PN. Makhalidwe a ma LED oyera oyenera ayenera kufananizidwa. Mu mawonekedwe a AC, chosinthira chiyeneranso kuganiziridwa. Makhalidwe amagetsi. Chifukwa chake, amayenera kuyesedwa kutsika kwamagetsi akutsogolo komanso kutsogolo kwamagetsi pamalo opangira, komanso magawo monga reverse leakage current ndi reverse breakdown voltage.
2. Kuwala kowala ndi kuwala kowala kwa LED yoyera
Mphamvu yonse yamagetsi yamagetsi yotulutsidwa ndi LED yoyera mu gawo la nthawi imatchedwa kuwala kowala, komwe ndi mphamvu ya kuwala (W). Kwa gwero loyera la kuwala kwa LED kuti liwunikire, chodetsa nkhawa kwambiri ndi mawonekedwe a kuwala, ndiko kuti, kuchuluka kwa kuwala kochokera ku gwero la kuwala komwe kungapangitse diso la munthu kuzindikira, lotchedwa luminous flux. Chiŵerengero cha kuwala kowala ku mphamvu yamagetsi ya chipangizochi chikuyimira kuwala kwa kuwala kwa LED yoyera.
3. Kuwala kwamphamvu kugawa kopindika kwa LED yoyera
Mphepete mwa kugawa kwamphamvu kwa kuwala kumagwiritsidwa ntchito kusonyeza kugawa kwa kuwala komwe kumachokera ku LED kumbali zonse za danga. Mu ntchito zowunikira, kugawa kwamphamvu ya kuwala ndi data yofunikira kwambiri powerengera kufanana kwa kuwala kwa malo ogwirira ntchito ndi makonzedwe a malo a ma LED. Kwa LED yomwe mtengo wake wa malo ndi wozungulira mozungulira, ukhoza kuimiridwa ndi mapindikidwe a ndege ya axis yamtengo; kwa LED yokhala ndi mtengo wa elliptical, mapindikidwe a ndege ziwiri zowongoka za axis ndi elliptical axis amagwiritsidwa ntchito. Kuyimira chithunzi chovuta cha asymmetrical, nthawi zambiri chimayimiridwa ndi mapindikidwe a ndege a magawo opitilira 6 a axis.
4, kugawa mphamvu zowonera zoyera za LED
Kugawa kwamagetsi kwa LED yoyera kumayimira ntchito ya mphamvu yowunikira ngati ntchito ya kutalika kwa mawonekedwe. Imatsimikizira mtundu wa luminescence ndi kusinthasintha kwake kowoneka bwino komanso index yowonetsa mtundu. Nthawi zambiri, kugawa mphamvu zowoneka bwino kumayimiridwa ndi mawu S(λ). Mphamvu yowoneka bwino ikatsikira ku 50% ya mtengo wake mbali zonse za pachimake, kusiyana pakati pa mafunde awiriwa (Δλ=λ2-λ1) ndi gulu lowonera.
5, kutentha kwamtundu ndi mtundu wopereka index wa LED yoyera
Kwa gwero la kuwala monga kuwala kwa LED komwe kumatulutsa kuwala koyera kwambiri, ma chromaticity coordinates amatha kufotokoza bwino mtundu wa gwero la kuwala, koma mtengo wake ndi wovuta kugwirizanitsa ndi maonekedwe a mtundu wa kuwala. Anthu nthawi zambiri amatchula mtundu wofiira wa lalanje ngati "mtundu wofunda", ndipo zotentha kwambiri kapena zamtundu wa buluu zimatchedwa "cold color". Choncho, ndizomveka kugwiritsa ntchito kutentha kwamtundu kusonyeza mtundu wowala wa gwero la kuwala.
7, kutentha kwa LED koyera
Kusintha kwa kuwala kwa LED ndi mphamvu zowunikira ndi imodzi mwazinthu zofunika kwambiri pakukula kwamakampani a LED. Panthawi imodzimodziyo, kutentha kwa PN kwa LED ndi vuto la kutentha kwa nyumba ndizofunikira kwambiri, ndipo nthawi zambiri zimasonyezedwa ndi magawo monga kukana kutentha, kutentha kwa kutentha, ndi kutentha kwa mphambano.
8, chitetezo cha radiation cha LED yoyera
Pakadali pano, International Electrotechnical Commission (IEC) ikufananiza zinthu za LED ndi zofunikira za semiconductor lasers pakuyesa chitetezo cha radiation ndikuwonetsa. Chifukwa LED ndi mtengo wopapatiza, chipangizo chowala kwambiri chotulutsa kuwala, poganizira kuti kuwala kwake kungakhale kovulaza diso la munthu, muyezo wapadziko lonse lapansi umatchula malire ndi njira zoyesera zama radiation ogwira ntchito a LED omwe amagwiritsidwa ntchito nthawi zosiyanasiyana. Chitetezo cha radiation pakuwunikira zinthu za LED pano chikugwiritsidwa ntchito ngati chofunikira pachitetezo ku European Union ndi United States.
9, kudalirika ndi moyo wa LED yoyera
Ma metric odalirika amagwiritsidwa ntchito kuyeza kuthekera kwa ma LED kuti agwire bwino ntchito m'malo osiyanasiyana. Moyo wonse ndi muyeso wa moyo wothandiza wa chinthu cha LED ndipo nthawi zambiri umawonetsedwa ndi moyo wothandiza kapena kutha kwa moyo. Mu ntchito zowunikira, moyo wogwira ntchito ndi nthawi yomwe imatengera kuti LED iwonongeke ku chiwerengero cha mtengo woyamba (mtengo wotchulidwa) pa mphamvu yovotera.
(1) Avereji ya moyo: Nthawi yotengedwa kuti gulu la ma LED liwunikire nthawi imodzi, pamene gawo la ma LED osawala limafika 50% pakapita nthawi.
(2) Moyo Wachuma: Poganizira zonse zowonongeka kwa LED ndi kuchepetsedwa kwa kuwala kwa kuwala, kutulutsa kophatikizana kumachepetsedwa mpaka nthawi inayake, yomwe ndi 70% ya magetsi akunja ndi 80% ya magetsi amkati.
