1. Jajab buluug-LED ah + nooca fosfooraska jaalaha ah-cagaaran oo ay ku jiraan nooca fosfooraska ee midabyo badan leh

 Lakabka fosfooraska jaalaha ah ee cagaarka ah wuxuu nuugaa qayb ka mid ahiftiin buluug ahchip-ka LED-ka si loo soo saaro photoluminescence, qaybta kalena ee iftiinka buluugga ah ee ka imanaya chip-ka LED-ka ayaa laga gudbiyaa lakabka fosfooraska waxayna ku biirtaa iftiinka jaalaha ah-cagaaran ee fosfooraska uu ka soo daayo meelo kala duwan oo booska ah, iftiinka casaanka, cagaarka iyo buluugga ahna waa la isku daraa si loo sameeyo iftiin cad; Sidan, qiimaha aragtiyeed ee ugu sarreeya ee hufnaanta beddelka photoluminescence ee fosfooraska, kaas oo ah mid ka mid ah hufnaanta quantum ee dibadda, kama badnaan doono 75%; heerka ugu sarreeya ee soo saarista iftiinka ee chip-ka wuxuu gaari karaa oo keliya qiyaastii 70%, markaa aragti ahaan, iftiinka buluugga ah ee cad. Hufnaanta ugu sarreysa ee iftiinka LED-ka kama badnaan doonto 340 Lm/W, CREE-na waxay gaartay 303Lm/W sannadihii la soo dhaafay. Haddii natiijooyinka baaritaanku ay sax yihiin, waxaa mudan in la dabaaldego.

2. Isku-darka casaanka, cagaarka iyo buluuggaRGB LEDnooca waxaa ku jira nooca RGBW-LED, iwm.

 Saddexda diode ee iftiinka soo saara ee R-LED (casaan) + G-LED (cagaar) + B- LED (buluug) ayaa la isku daraa, saddexda midab ee aasaasiga ah ee casaanka, cagaarka iyo buluugga ayaa si toos ah loogu qasaa booska si ay u sameeyaan iftiin cad. Si loo soo saaro iftiin cad oo hufan sidan, marka hore, LED-yada midabada kala duwan leh, gaar ahaan LED-yada cagaaran, waa inay ahaadaan ilo iftiin oo hufan, kuwaas oo laga arki karo "iftiinka cad ee tamarta siman" kaas oo iftiinka cagaaran uu yahay qiyaastii 69%. Waqtigan xaadirka ah, waxtarka iftiinka ee LED-yada buluugga ah iyo kuwa cas aad ayuu u sarreeyay, iyadoo waxtarka gudaha ee kutaanta uu ka badan yahay 90% iyo 95%, siday u kala horreeyaan, laakiin waxtarka kutaanta gudaha ee LED-yada cagaaran aad ayuu uga dambeeyaa. Dhacdadan hufnaanta iftiinka cagaaran ee hooseeya ee LED-yada ku salaysan GaN waxaa loo yaqaan "farqiga iftiinka cagaaran." Sababta ugu weyn ayaa ah in LED-yada cagaaran aysan helin agabkooda epitaxial. Alaabada taxanaha fosfooraska ee arsenic nitride ee jira waxay leeyihiin hufnaan hoose oo ku jirta muuqaalka jaalaha-cagaaran. Agabka epitaxial-ka cas ama buluugga ah ayaa loo isticmaalaa in lagu sameeyo LED-yada cagaaran. Marka ay jirto cufnaanta hadda jirta oo hooseysa, sababtoo ah ma jiro luminta beddelka fosfooraska, LED-ka cagaaran wuxuu leeyahay hufnaan iftiin oo ka sarreeya iftiinka cagaaran ee nooca buluugga ah + fosfooraska. Waxaa la soo sheegay in hufnaantiisu ay gaarto 291Lm/W marka loo eego xaaladda hadda jirta ee 1mA. Si kastaba ha ahaatee, hoos u dhaca hufnaanta iftiinka ee iftiinka cagaaran ee uu keeno saameynta Droop ee hoos timaada hadda jirta oo weyn waa mid muhiim ah. Marka cufnaanta hadda jirta ay korodho, hufnaanta iftiinku si dhakhso ah ayay hoos ugu dhacdaa. Hadda oo ah 350mA, hufnaanta iftiinku waa 108Lm/W. Marka ay jirto xaaladda 1A, hufnaanta iftiinku way hoos u dhacdaa. Ilaa 66Lm/W.

Fosfiinnada III, sii deynta iftiinka ee ku socota xarigga cagaaran ayaa noqotay caqabad aasaasi ah oo ku wajahan nidaamka maaddada. Beddelidda qaab-dhismeedka AlInGaP si ay uga dhigto mid soo saarta iftiin cagaaran halkii ay ka ahaan lahayd casaan, oranji ama jaalle - taasoo keenta xaddidaad aan ku filnayn oo sideyaasha ah ayaa sabab u ah farqiga tamarta ee hooseeya ee nidaamka maaddada, kaas oo ka reebaya isku-darka shucaaca wax ku oolka ah.

Sidaa darteed, habka loo hagaajiyo hufnaanta iftiinka ee LED-yada cagaaran: dhinaca kale, baro sida loo yareeyo saamaynta Droop iyadoo la raacayo xaaladaha walxaha epitaxial ee jira si loo hagaajiyo hufnaanta iftiinka; dhinaca labaad, isticmaal beddelka photoluminescence ee LED-yada buluugga ah iyo fosfoorasyada cagaaran si aad u soo saarto iftiin cagaaran. Habkani wuxuu heli karaa hufnaan iftiin sare leh oo iftiin cagaaran, kaas oo aragti ahaan gaari kara hufnaan iftiin ka sarreeya iftiinka cad ee hadda jira. Waxay ka tirsan tahay iftiinka cagaaran ee aan iskeed u dhicin. Ma jirto wax dhibaato ah oo ku saabsan iftiiminta. Saamaynta iftiinka cagaaran ee habkan laga helo waxay ka badnaan kartaa 340 Lm/W, laakiin weli ma dhaafi doonto 340 Lm/W ka dib marka la isku daro iftiinka cad; saddexaad, sii wad cilmi-baarista oo hel walxahaaga epitaxial, kaliya Sidan, waxaa jira rajo yar oo ah in ka dib marka la helo iftiin cagaaran oo aad uga sarreeya 340 Lm/w, iftiinka cad oo ay weheliso saddexda midab ee aasaasiga ah ee LED-yada casaanka, cagaarka iyo buluugga ah ay ka sarreyn karaan xadka hufnaanta iftiinka ee LED-yada cad ee buluugga ah ee 340 Lm/W.

3. Nalalka Ultraviolet-kajajab + saddex fosfooraska midabka aasaasiga ah ayaa iftiimiya iftiin 

Cilladda ugu weyn ee labada nooc ee LED-yada cad ee kor ku xusan waa qaybinta aan sinnayn ee booska ee iftiinka iyo midabka. Iftiinka ultraviolet-ka ma arki karo isha aadanaha. Sidaa darteed, ka dib marka iftiinka ultraviolet-ku ka baxo jajabka, waxaa nuuga saddexda fosfooraska midabka aasaasiga ah ee lakabka daboolista, oo loo beddelo iftiin cad iyadoo la adeegsanayo iftiinka fosfooraska, ka dibna loo sii daayo booska. Tani waa faa'iidadiisa ugu weyn, sida laambadaha iftiinka ee dhaqameed, ma laha sinnaan la'aanta midabka booska. Si kastaba ha ahaatee, waxtarka iftiinka aragtiyeed ee LED-ka iftiinka cad ee nooca jajabka ultraviolet-ka ma noqon karo mid ka sarreeya qiimaha aragtiyeed ee iftiinka cad ee nooca jajabka buluugga ah, iska daa qiimaha aragtiyeed ee iftiinka cad ee nooca RGB-ka ah. Si kastaba ha ahaatee, iyada oo loo marayo horumarinta fosfooraska saddex-asal ah ee waxtarka sare leh ee ku habboon kicinta iftiinka ultraviolet-ka ayaa suurtagal ah in la helo LED-yada iftiinka cad ee ultraviolet-ka ah ee u dhow ama xitaa ka sarreeya labada LED-yada iftiinka cad ee kor ku xusan marxaladdan. Inta ugu dhow ee LED-ka iftiinka ultraviolet-ka buluugga ah, suurtagalnimada. Weynaanta LED-ka iftiinka cad ee hirarka dhexdhexaadka ah iyo nooca ultraviolet-ka hirarka gaaban waa wax aan macquul ahayn.
