Sidee bay LED-ku u soo saaraan iftiin?

Koronto-dhalinta (Electroluminescence) waa habka ay LED-yada (Nalalka Soo Saaraya Iftiinka) u dhaliyaan iftiin. Sidan ayay u shaqeysaa:

1-Qalabka Semiconductor-ka: Walax semiconductor ah, oo badanaa isku dar ah walxo sida fosfooraska, arsenic, ama gallium, ayaa loo isticmaalaa in lagu sameeyo LED. Labada qaybood ee nooca n-nooca (negative), oo leh elektaroono xad dhaaf ah, iyo gobolka nooca p-nooca (positive), oo leh la'aanta elektaroono (godad), waxaa la soo saaraa marka semiconductor-ku uu ku jiro wasakh.

Isu-dubaridka 2-Elektaroonka-Godadka: Elektaroonada ka soo jeeda aagga nooca n-ka ayaa lagu qasbayaa inay u gudbaan gobolka nooca p marka danab la dhigo LED-ka. Elektaroonadani waxay dib ugu biiraan godadka gobolka nooca p-ka.

3-Footanta Sawir-qaadista: Tamarta waxaa lagu soo saaraa iftiin ahaan (fotoonno) inta lagu jiro habkan isku-dhafka ah. Kala-goynta tamarta ee walxaha semiconductor-ka ee la isticmaalo waxay go'aamisaa midabka iftiinka la sii daayo. Iftiinku wuxuu ku yimaadaa midabyo kala duwan iyadoo ku xiran maaddada.

4-Hufnaan: Maadaama inta badan tamarta ku jirta LED-yada loo beddelo iftiin halkii laga isticmaali lahaa kulayl—dhibaato caadi ah oo ku timaadda nalalka caadiga ah ee ololka—LED-yadu aad bay waxtar u leeyihiin.

5-Ku-xidhnaan: Marka LED-ka lagu xidho resin ama muraayad cad, iftiinka uu soo saaro si joogto ah ayaa loo hagaajiyaa. Tani waxay sidoo kale gacan ka geysan kartaa in la kala furfuro iftiinka oo uu ka dhigo mid si fiican u muuqda.

Marka la barbardhigo hababka iftiinka caadiga ah, habkani wuxuu awood u siinayaa LED-yada inay bixiyaan iftiin xooggan oo xooggan iyadoo la isticmaalayo tamar aad u yar.

Iyadoo ay dheer yihiin cimri dheer iyo hufnaantooda, nalalka LED waxay yeelan karaan dhowr arrimood oo caadi ah, sida:
1) Kala duwanaanshaha Heerkulka Midabka: Iftiinka aan isku mid ahayn ee meel ayaa ka dhalan kara isbeddellada heerkulka midabka ee u dhexeeya dufcadaha nalalka LED-ka.

2) Dabacsanaan: Marka loo isticmaalo badhanka dimmer-ka ee aan iswaafaqsanayn ama marka ay jiraan dhibaatooyin ku saabsan korontada, nalalka LED-ka qaarkood ayaa laga yaabaa inay dabacsanaadaan.

3) Kulayl xad dhaaf ah: Nalalka LED-ku waxay soo saaraan kulayl ka yar nalalka caadiga ah, laakiin kulaylka oo aan ku filnayn ayaa sababi kara kulayl xad dhaaf ah, taasoo yarayn karta cimriga nalalka.

4) Dhibaatooyinka Darawalada: Si loo xakameeyo korontada, nalalka LED-ka waxay u baahan yihiin darawallo. Iftiinku wuu libdhi karaa, madoobaan karaa, ama gebi ahaanba wuu joojin karaa shaqada haddii darawalku cilladoobo ama uu tayo hooseeyo.

5) Iswaafajinta Hoos u Dhigista: Dhibaatooyinka waxqabadka ayaa laga yaabaa inay soo baxaan sababtoo ah qaar ka mid ah nalalka LED-ka ayaa aan la jaan qaadi karin badhanka hoos u dhigista ee hadda jira.

6) Xagasha Iftiinka Xaddidan: Iftiin aan sinnayn ayaa ka dhalan kara nalalka LED-ka oo leh xagal iftiin oo xaddidan, taas oo laga yaabo inaysan ku habboonayn codsiyo badan.

7) Qiimaha Bilowga ah: Inkasta oo nalalka LED-ku ay lacag kaydsadaan waqti ka dib, haddana waxay ku kici karaan qiimo ka badan inta lagu iibsado marka loo eego nalalka caadiga ah.

8) Walaacyada Deegaanka: Haddii aan si habboon loo tuurin, heerarka raadadka walxaha khatarta ah sida rasaasta ama arsenic ee laga helo qaar ka mid ah nalalka LED-ka ayaa khatar gelin kara deegaanka.

9) Isbeddelka Tayada: Waxaa jira alaabooyin badan oo kala duwan oo LED ah oo suuqa yaal, dhammaantoodna laguma sameeyo heer isku mid ah, taasoo keenta isbeddelo ku yimaada cimriga iyo waxqabadka.

10) La'aanta Qalabka qaarkood: Nalalka LED qaarkood, gaar ahaan kuwa loo sameeyay nalalka caadiga ah ee dhalaalaya, si fiican uma shaqeyn karaan qalabka gaarka ah.

Doorashada alaab tayo sare leh, hubinta inay la shaqeeyaan nidaamyada hadda jira, iyo sida ku cad tilmaamaha rakibidda ayaa badanaa lagama maarmaan u ah xallinta dhibaatooyinkan.

Waxaa jira xariijimo badan oo nalalka ah oo laga dooran karo suuqa hadda, sidaXarigga COBXarriiqda CSP, way ka duwan tahayXarig SMD ah, nala soo xiriir haddii aad u baahan tahay muunado baaritaan ah.
