Dooro ishan laydhka ee isku dhafan ee jeermis dilay. Isha iftiinka COB waa tignoolajiyada isha iftiinka ee isku-dhafan ee-iftiinka sare leh kaas oo si toos ah ugu xidhan substrate birta muraayada ah ee chip LED si toos ah heerka iftiinka sare ee-rogista. Farsamadani waxay meesha ka saaraysaa fikradda bracket-ka. Isha iftiinka LED-ka oo leh tamar iftiin badan ayaa la soo saaray, moduleka kaliya ayaa looga baahan yahay inuu yeesho cufnaanta koronto iyo koronto sare. Tignoolajiyada gaarka ah ee isha iftiinka LED waxay bilaabatay qiyaastii 2000, horumarkeeduna wuxuu ahaa mid gaabis ah. Shirkadaha guduhu ma lahayn wax soo saar, halka wadamada shisheeye, Osram iyo Langamas, USA, ay bixin karaan. Midabka iftiimiya iftiinka iyo waxtarka iftiinka iftiinka iftiinka iftiinka ee isku-dhafan ee LED waxay la xiriiraan qalabka iyo hababka samaynta LEDs. Hadda, waxaa jira saddex nooc oo casaan, cagaar, buluug ah (R, G, B). Sababtoo ah korantada shaqada ee hooseysa ee LED (kaliya 1.5-3V), waxay si firfircoon u ifin kartaa oo yeelan kartaa iftiin gaar ah, iftiinka waxaa lagu hagaajin karaa danab (ama hadda). Qalabka bandhiga, ma jiro qaab kale oo soo bandhig ah hadda iyo qaabka bandhiga LED. Ma jiro koronto-dhal, dib-u-dhac ma leh, ma jiro hab-raac balastar ah, markaa habka waxaa la dhimay ku dhawaad ​​​​saddex-meelood meel, kharashka sidoo kale waxaa lagu badbaadiyay saddex meelood meel. Waa maxay isha iftiinka LED? Asxaabta aan aqoon su'aashan waxay inta badan weydiiyaan saaxiibo aqoon u leh mashruuca. Marka la barbardhigo ilaha iftiinka dhaqameed, mugga ilaha iftiinka LED waa yar yahay. Sidaa darteed, waxaa jira saadaal yar oo caqli badan oo suuqa hadda jira. Naqshadeynta iftiinka dariiqa LED-ka waa qaabka naqshadeynta indhaha ee labaad. Waxaan ku tooganaa iftiinka nalalka waddooyinka ee LED-ka meesha iftiinka looga baahan yahay, taas oo ka dhigi karta mid waxtar leh. Nalalka LED-yada waxay leeyihiin nolol adeeg oo dheer. Ka dib 10 sano oo la isticmaalay, nalalka LED-yada ayaa weli leh qiime isticmaalka sare. Uma fiicna 3% habka isticmaalka joogtada ah ee hal sano. Nalalka laydhka ee laydhka LED-ku waa qalab korantada hooseeya, kaas oo badbaado u ah isticmaalka danabka. Sida casriga casriga ah, gaar ahaan qaybta xudunta u ah muraayadaha isku dhafan, garaaca garaaca tayada sare leh iyo ilaha iftiinka laysarka ee la xidhiidha ayaa had iyo jeer ahaa diiradda muhiimka ah ee wareegyada tacliinta iyo warshadaha. Fasalka B ee Sayniska iyo Tignoolajiyada Gaarka ah ee Hormoodka Istaraatiijiyadeed ee Heerka B ee Akadeemiyada Sayniska Shiinaha “Chip isku-dhafan oo cabbir weyn leh ”Iyada oo taageero laga helayo, dhawaan, kooxda isku dhafan ee micro-nainer iyo photon ee Xi'an Optical Machine. Isha iftiinka isku dhafan ayaa dhab ahaantii sababtoo ah isha iftiinka LED waa la qaatay. Sidaa darteed, waxaa jiri kara faa'iido mug leh. Isha iftiinka guluubka dhaqameed wuxuu u baahan yahay meel weyn si uu u baabi'iyo kulaylka. Marka laga hadlayo ilaha iftiinka LED-ka ee bilaashka ah, LED pan-light light waa il dhibic oo si siman loogu iftiimin karo dhammaan jihooyinka. Xajmiga shucaaca waxa loo hagaajin karaa si aan loo kala sanayn. Alaabooyinka ay shirkaddu soo saarto ayaa ah mid si weyn loogu isticmaalo nalalka cadceedda, nalalka dawladda hoose, qalabka isgaadhsiinta, badbaadada gaadiidka iyo qaybaha kale, iwm. Alaabooyinka ugu muhiimsan ee la soo saaro waa: nalalka waddooyinka, nalalka waddooyinka, nalalka barxadda, nidaamyada tamarta tamarta qoraxda, nalalka LED, koontaroolka LED, nalalka muuqaalka LED, nalalka aluminiumka ah ee dhinta, kontaroolayaasha tamarta dabaysha, kontaroolayaasha tamarta qoraxda iyo awood kale qalabka qaybinta. Sababta ugu weyn ee fashilka weyni waa jaalaha ama yaraynta silikoonka ama hoos u dhigista. LED-yada rasmiga ah ee P iyo N waxay ku yaalaan isla dhinaca LED-ka. Hadda waa in uu u gudbaa lakabka N-GAN si siman, taaso keeneysa hadda ciriiri ah, kulayl sare oo maxalli ah, iyo xaddidaya socodka hadda. Qarsoon Habka isticmaalka muddada dheer, heerkulka sare ee uu keeno kuleylka liidata wuxuu saameeyaa waxqabadka iyo gudbinta silikoon, taas oo keenta koronto koronto oo iftiin leh. Isha iftiinka isku-dhafan ee digsiga-iftiinku waa ilayska ugu badan ee la isticmaalo marka la bixinayo. Nalalka caadiga ah ee digsiga-iftiinka ayaa loo isticmaalaa in lagu iftiimiyo goobta oo dhan. Waxaad isticmaali kartaa nalal badan oo digsi-iftiin ah goobta si aad u soo saarto natiijooyin wanaagsan.
