Yintoni ebangela ukuba i-chip emhlophe ye-LED isweleke?

Abavelisi abaninzi basebenzisa nje izinto ezingabizi kakhulu nezikumgangatho ophantsi ukuthoba amaxabiso ezibane ukuze bahende abathengi. Izinga lezikhalazo ezisemgangathweni malunga nezibane zepaneli ze-LED eziMHLOPHE zinyukile kule minyaka mibini idlulileyo ngenxa yoku. Umbala otyheli wendawo yokukhanya yenye yazo, kwaye imbi kakhulu. Siza kuthetha ngezizathu zokuba kutheni Mhlophe itshiphu ye-LED emhlophe  fa. Ngaphandle kokuqhubeka, masingene kanye.

Yintoni i itshiphu ye-LED emhlophe ?

Ukuveliswa kokukhanya okuMhlophe nge-LED EMHLOPHE kunokufezekiswa ngeendlela ezimbini ezahlukeneyo. Indlela ye-RGB yeyokuqala, kwaye indlela ye-phosphor yeyesibini. Indlela ye-phosphor yeyona nto isetyenziswa rhoqo kwicandelo lokukhanyisa. Ubuchwephesha be-phosphor benza ipakethe ye-LED EMHLOPHE eyenza ukukhanya okumhlophe ngokugquma iblue itshiphu ye-LED emhlophe ngephosphor etyheli.

Ngokudibanisa nje izibane ezibomvu, eziluhlaza, neziluhlaza ngokwemilinganiselo efanelekileyo, ukukhanya okumhlophe kuveliswa kusetyenziswa ubuchule beRGB.

Ubuchwephesha be-phosphor benza ipakethe ye-LED EMHLOPHE eyenza ukukhanya okumhlophe ngokugquma iblue itshiphu ye-LED emhlophe  ngephosphor etyheli. Umaleko wefluorescent omthubi uvumela ukukhanya okuluhlaza okwesibhakabhaka oveliswe yi itshiphu ye-LED emhlophe  ukudlula, ukudala ukukhanya okumhlophe ngomxube weblues kunye neefotoni ezityheli.

Kwinqanaba le-chip, i-diode ye-light-emitting (LED) iqulethwe ngezinto ze-semiconductor ezenziwe nge-doped ukwenza i-p-n junction. Ngokusebenzisa i-bias yangoku ehamba phambili kwi-junction, umntu unokunyanzela ii-electrons ukuba zihambe ukusuka kwi-n-type conduction band ukuya kwi-p-type conduction band. Oku kuhlanganiswa kwakhona yinkqubo yokukhanya, kuninzi lweziganeko, kubangela ukuveliswa kwefoton ene-wavelength egqitywe yi-bandgap yezinto eziphathekayo.

Emva kwepateni ye-LED EMHLOPHE  I-wafer, iyasikwa ngokulandelayo, kwaye umntu ofileyo owenza i-wafer iyadityaniswa kwaye ipakishwe. Kuyimfuneko ukudibanisa i-LED EMHLOPHE  ukuya kukhokelela usebenzisa iingcingo ezicikizeke kakhulu, eziqhele ukwenziwa ngegolide, ukuze kuveliswe umsinga oya phambili oyimfuneko ekufumaneni ukukhanya kwi-LED EMHLOPHE.

Ngoba itshiphu ye-LED emhlophe s Ukufa?

I-LED OMHLOPHE idla ngokufumana enye yeentlobo ezimbini eziphambili zokusilela: ukuqhubela phambili okanye intlekele. Ukusilela kwe-LED EMHLOPHE  kusenokwenzeka ukuba ibangelwe kukuwohloka okucothayo ekuhambeni kwexesha ngokuchasene nokuguqulwa kwequbuliso, ngaphandle kwezinto ezimbalwa kakhulu. Ukungaphumeleli, emehlweni abathengisi, akusiyo imeko yombuso-mbini kodwa kunokuba inqaku elicacileyo ekuqhubekeni kwamanqanaba okusebenza. Ngokophando, iliso lomntu likwazi ukubona utshintsho ukuya kuthi ga kwi-30 yepesenti kwi-flux ekhanyayo ngaphambi kokuba ukukhutshwa kwesibane kwehle ngolo hlobo. Njengesiphumo soku, uninzi lwabavelisi bachaza umjikelo wobomi besixhobo njengendawo apho isiphumo saso esikhanyayo siwela ngaphantsi kweepesenti ezingama-70 exabiso ebesinalo ekuqaleni.

Noko ke, oku akuthethi ukuba ukusilela okuyintlekele akunakuze kwenzeke. Ngokwenyani, amathuba okuba esinye sezixhobo zakho siyeke ukusebenza ngokufanelekileyo ngaxa lithile anyuka ngokulinganayo kunye nobunzima beemeko zokusebenza. Kukho, nangona kunjalo, amanyathelo onokuthi uwathathe ukunciphisa ifuthe lezinto ezininzi kwaye wandise amathuba okuba isicelo sakho samkelwe.

Ukusilela kwezinto

WHITE LED  ukusebenza kunye nobomi buxhomekeke kumgangatho wezinto eziphathekayo. Ukudityaniswa komngxuma we-Electron kuya kubangela ukubola kwe-nonradiative ukuba izinto zineziphene ezininzi. Uninzi olumhlophe-okukhanya EMHLOPHE ii-LED zenziwa kwisapphire substrates egqunywe ngeGaN. Uxinzelelo olusuka kwilathisi engahambelaniyo lubangela ukutsalwa kwemisonto. Iintanda ezintle zisasaza ngokuthe nkqo ukusuka kwifilimu ye-GaN ukuya kwindawo esebenzayo, kubange ukubola okungeyomfuneko. Imveliso yesibane iyancipha njengoko ukubola okungabonakaliyo kunyuka. I-Thermocycling inokusasaza ezi ziphene.

Ukuvuza kwangoku kwiimpazamo zesakhiwo kuvumele umva-umtyalo wokuhamba ngoku. Inaliti yomthwali ngendawo esebenzayo inokudala okanye isasaze iziphene. Ukuxinana kwesiphene kwehlisa amandla ombane, okuchaphazela ukusebenza.

Umsinga ophezulu unokubangela iziphene kwicala le-p lesiphambuka. Uxinzelelo lombane lonakalise i-ultraviolet EMHLOPHE LED s ngaphezu koxinzelelo lobushushu. Zhuhai Tianhui Electronic Co., Ltd.   I-LED epholileyo emhlophe ilungele ukusetyenziswa kwe-ultra-bright. Umphezulu - isixhobo esixhonyiweyo sinokubamba i-2.8 A yangoku yangoku kwimveliso ye-900 lm.

Ukuqhuba ngaphezulu kwe-LED EMHLOPHE

Ukuqhuba ngaphezulu kwe-LED EMHLOPHE  inokonakalisa imveliso kunye nobomi. Ukusetyenziswa kokukhanya okuphezulu, khankanya isixhobo esinje nge-LED emhlophe epholileyo, enokukhupha i-900 lm kwi-2.8 A.

WHITE LED  iimpazamo aziphelelanga kwimidiya esebenzayo. I-epoxy encapsulate ikhusela ukufa, kodwa inokubangela iingxaki. Izinto ezifunxayo zinokudlulisela ukufuma okanye iikhemikhali ze-caustic ekufeni kwindawo efumileyo okanye eyonakalisayo. Abafowunelwa be-Corrod banokwenza iifutshane okanye i-overvoltage. I-passivation inokunciphisa le mpembelelo, kodwa izixhobo kufuneka zikhuselwe kwiimeko ezishushu, ezinomswakama.

Iimpazamo zombane

I-Electromigration, inkqubo ezenzekelayo ephuculwa kukufuma okanye iimeko ezifumileyo, inokuvelisa ngokuzenzekelayo imicu ukusuka kwisinyithi njengesilivere efakwe kwintlama esetyenziselwa ukuncamathela ii-LED ezingaphezulu kwiibhodi. Ziphephe ii-LED ezingafakwanga.

WHITE LE D Ukuvezwa kwi-high-voltage electrostatic discharge inokusilela ngokwentlekele. I-Ultra-high-voltage spikes ixhaphakile. Ukuhamba kwigumbi elinekhaphethi kunokukuhlawulisa ukuya kuthi ga kwi-1.5 kV, kuxhomekeke kubumanzi kunye nezihlangu. Olo sothuko lunokoyisa ukuxhathisa kwe-electrostatic imathiriyeli ye-semiconductor xa kusiwa ekufeni. Ukufudumeza okugqithisileyo kwendawo ukusuka ekukhupheni kunokugqobhoza imidiya esebenzayo, kubangele ukusilela kwesekethe emfutshane.

Apho Ukuthenga Mhlophe itshiphu ye-LED emhlophe  Oko Kuhlala Ixesha Elide

Zhuhai Tianhui Electronic Co., Ltd.  ngumgangatho ophezulu UV Abavelisi be-LED  ngokukhethekileyo kwi-UV EMHLOPHE ye-LED yokucoca umoya, i-UV EMHLOPHE yokucoca i-LED yokucocwa kwamanzi, i-UV EMHLOPHE yokuprinta i-LED yokuprinta, UV White LED diode , uv   Ikhokela Imodyuli , kunye nezinye izinto.
