Sidee bay LED u soo saartaa iftiinka?

Electroluminescence waa habka ay LED-yadu (Light Emitting Diodes) u dhaliyaan iftiin. Tani waa sida ay u shaqeyso:

1-Semiconductor Material: Walxaha semiconductor, sida caadiga ah isku dhafka walxaha sida fosfooraska, arsenic, ama gallium, ayaa loo isticmaalaa in lagu sameeyo LED. Labada aagga n-nooca (negative), kaas oo leh xad-dhaaf ah oo elektaroonik ah, iyo nooca p-nooca (positive), kaas oo leh la'aanta elektarooniga (godadka), ayaa la soo saaraa marka semiconductor lagu daro wasakh.

2-Electron-Hole Dib-u-habaynta: Electrons-ka aagga n-nooca waxaa lagu qasbayaa dhinaca gobolka-nooca marka koronto la dhigo LED-ga. Electrons-yadani waxay dib ula midoobaan godadka gobolka nooca p.

3-Sawir sii daaya: Tamartu waxay u soo baxaysaa iftiin ahaan (sawiro) inta lagu jiro habka dib-u-habaynta. Farsamaynta tamarta ee walxaha semiconductor ee la adeegsaday ayaa go'aamiya midabka iftiinka la sii daayo. Iftiinku wuxuu ku yimaadaa midabyo kala duwan iyadoo ku xiran walxaha.

4-Wax-ku-oolnimada: Maadaama inta badan tamarta LED-yada loo beddelo iftiin halkii ay ka ahaan lahayd kulayl-dhibaatada caadiga ah ee nalalka caadiga ah - LEDs ayaa si cajiib ah waxtar u leh.

5-Xoojinta: Marka laydhka lagu dhejiyo resin ama lens cad, iftiinka uu sii daayo ayaa badanaa la hagaajiyaa. Tani waxay sidoo kale gacan ka geysan kartaa in la faafiyo iftiinka oo laga dhigo mid ka sii wanaagsan.

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

In kasta oo ay cimri dheer yihiin iyo waxtarkooda, nalalka LED waxay yeelan karaan dhowr arrimood oo caadi ah, sida:
1) Kala duwanaanta heerkulka midabka: Iftiinka aan isku midka ahayn ee aaggu wuxuu ka dhalan karaa isbeddelka heerkulka midabka ee u dhexeeya qaybaha nalalka LED.

2) Flickering: Marka loo isticmaalo shideeyaha dimmer-ka ee aan ku habboonayn ama marka ay jiraan dhibaatooyin xagga korontada ah, nalalka LED-yada qaarkood ayaa lilli kara.

3) Kuleyl badan: LED-yadu waxay soo saaraan kulayl ka yar nalalka caadiga ah, laakiin kulaylka aan ku filnayn wuxuu keeni karaa kulayl, taas oo yareyn karta nolosha nalalka.

4) Dhibaatooyinka Darawalka: Si loo xakameeyo awoodda, nalalka LED waxay u baahan yihiin darawallo. Iftiinku waxa laga yaabaa inuu libido, bakhtiimo, ama gabi ahaanba joojiyo shaqada haddii darawalku xumaado ama uu tayadiisu hoosayso.

5) Waafaqsanaanta Dimming: Dhibaatooyinka waxqabadka ayaa laga yaabaa inay soo baxaan sababtoo ah nalalka LED-yada qaarkood ayaan la socon karin furayaasha hadda jira.

6) Xagalka Beam ee xaddidan: Nalalka aan sinnayn waxay ka dhalan karaan nalalka LED-ka oo leh xagal xaddidan, oo laga yaabo inaysan ku habboonayn codsiyo badan.

7) Qiimaha ugu horeeya: Inkastoo nalalka LED ay lacag badbaadiyaan waqti ka dib, waxay ku kici karaan wax ka badan iibsashada marka hore marka loo eego nalalka caadiga ah.

8) Walaaca deegaanka: Haddii aan si habboon loo tuurin, heerarka raadraaca walxaha khatarta ah sida sunta rasaasta ama arsenic ee laga helo nalalka LED-yada qaarkood waxay khatar gelin karaan deegaanka.

9) Kala duwanaanshaha tayada: Waxaa jira alaabooyin badan oo kala duwan oo LED ah oo suuqa yaal, dhammaantoodna maaha kuwo la soo saaray si isku mid ah, taas oo keenta kala duwanaansho cimri dherer iyo waxqabad.

10) La jaanqaadi la'aanta Qalabka qaarkood: Nalalka LED-yada qaarkood, gaar ahaan kuwa loo sameeyay nalalka caadiga ah, si fiican uma shaqayn karaan qalabyo gaar ah.

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

Waxaa jira xariijin iftiin badan oo laga dooran karo suuqa hadda, sidaXariijimaha COBXarigga CSP, oo ka duwan kanxariijin SMD, nala soo xidhiidh haddii aad u baahan tahay muunado tijaabo ah.
