Laambadaha LED-ku waa laambadaha diode-ka ee bixiya iftiinka. Sida isha iftiinka dawladeed ee adag,Nalalka LED-kaway ka duwan yihiin ilaha iftiinka ee soo jireenka ah marka loo eego qiiqa sii daaya, waxaana loo tixgeliyaa sida nalalka iftiinka cagaaran. Nalalka LED-ka ayaa lagu dabaqay meelo kala duwan oo leh faa'iidooyinkooda waxtarka sare leh, badbaadinta tamarta iyo codsiga dabacsan, waxayna si tartiib tartiib ah u noqdaan badeecada ugu weyn ee suuqa iftiinka. Marka lagu daro iftiinka guriga,Nalalka warshadaha LEDNalalka LED-ka ayaa sidoo kale si weyn loogu isticmaalaa afarta qaybood ee soo socda:

1. Nalalka gaadiidka

Maaddaama nalalka LED-ku ay ka cimri dheer yihiin nalalka caadiga ah, nalalka calaamada taraafigga oo aad u badan ayaa dooranaya isticmaalka LED-ka. Iyadoo horumarinta warshaduhu ay sii kordhayaan oo aad u bislaaday, qiimaha iftiinka aadka u sarreeya ee AlGaInP cas, orange iyo LEDs jaalaha ah maaha mid aad u sarreeya. Si loo hubiyo badbaadada, qaybo ka kooban LEDs dhalaalaya oo aad u sarreeya ayaa loo isticmaalaa si loogu beddelo nalalka taraafigga ee shidan ee cas.

2. Iftiin otomaatig ah

Codsiga nalalka LED-ka ee awoodda sare leh ee goobta iftiinka baabuurta ayaa si joogto ah u koraya. Bartamihii 1980-meeyadii, LED waxa markii ugu horaysay loo adeegsaday nalalka biriiga. Hadda baabuurta intooda badani waxay dooran doonaan LED-ka wadista maalintii, iyo nalalka LED-ka ayaa sidoo kale beddelaya nalalka xenon sida doorashada guud ee nalka hore ee baabuurta.

3. Fosfoor oo tayo sare leh

Chip buluug ah oo lagu dahaadhay fosfoor cagaaran oo jaale ah ayaa ah tignoolajiyada codsiga fosfor cad ee inta badan la isticmaalo. Chipku waxa uu sii daayaa iftiin buluug ah, fosfoorkuna waxa uu sii daayaa iftiin huruud ah ka dib markii uu ku farxay iftiinka buluuga ah. Substrate-ka buluuga ah ee LED-ku wuxuu ku go'an yahay gunta oo lagu daboolay jel silica ah oo daboolan oo lagu daray fosfoor cagaaran oo jaale ah. Iftiinka buluugga ah ee ka soo baxa substrate-ka LED waxa qayb ka mid ah nuuga fosfoorka, halka qaybta kale ee nalka buluuga ah lagu dhex daraa iftiinka jaalaha ah ee fosfoorka si loo helo iftiin cad.

4. Nalalka qurxinta ee goobta dhismaha.

Sababtoo ah cabbirka yar ee LED, waxay ku habboon tahay in la xakameeyo dhalaalka firfircoon iyo midabka, sidaas darteed waxay ku habboon tahay dhismaha qurxinta, sababtoo ah dhalaalkeeda sare, ilaalinta tamarta iyo ilaalinta deegaanka, cabbir yar iyo isku-dhafka fudud ee dusha sare ee dhismaha.
