Ziziphi izinto ezichaphazela i-AC-free LED Light Effective

1. Itekhnoloji yokutshatyalaliswa kobushushu Kwi-diode-emitting diode eyenziwe nge-PN, xa i-front current ihamba ukusuka kwi-PN, i-knot ye-PN inokulahleka kokufudumeza. Ezi khalori zisasazwa emoyeni ngokusebenzisa iglue edibeneyo, izinto zokunkcenkceshela, ukutshisa ukushisa, njl., kwaye zisasazwe emoyeni. Kule nkqubo, inxalenye nganye yezinto inokumelana nobushushu ukuthintela ukuhamba kobushushu, oko kukuthi, ukumelana nobushushu, i-AC -free LED ukumelana ne-thermal yixabiso elisisigxina elinqunywe ubungakanani besixhobo, isakhiwo kunye nezinto eziphathekayo. Ukuxhatshazwa kwe-thermal diode yokukhanya yi-RTH (/ w), kunye namandla okutshatyalaliswa kobushushu yiPD (W). Ngeli xesha, iqondo lokushisa le-PN le-knot elibangelwa ukulahleka kobushushu bexesha langoku liphakama ukuya: t () = Rth PD. Ubushushu be-PN knot yile: TJ = TARTH PD, apho i-TA bubushushu be-ambient. Njengoko ukushisa okunyukayo kweqhina kuya kunciphisa ithuba lokudibanisa i-PN, ukukhanya kweediode ezikhanyayo kuya kuncipha. Ngexesha elifanayo, ngenxa yokunyuka kweqondo lokushisa okubangelwa ukulahleka kwe-thermal, ukukhanya kwe-diode yokukhanya-emitting akusayi kuqhubeka nokunyuka kunye nomlinganiselo wangoku, oko kukuthi, i-phenomenon ye-thermal saturation. Ukongeza, ngokunyuka kweqondo lobushushu leqhina, i-wavelength ekhanyayo iya kukhukuliseka kwicala lamaza amade, malunga ne-0.2-0.3nm/, eyeye-LED emhlophe engena-AC yi-LED emhlophe engena-AC. ngokugquma i-YAG fluorescent powder nge-chip ye-Blu-ray. I-drift ye-Blu-ray wavelength iya kubangela umdlalo olahlekileyo kunye nomgubo we-fluorescent ukuvuselela ubude be-wavelength, ngaloo ndlela kuncitshiswe ukusebenza kakuhle kokukhanya kokukhanya okumhlophe kwe-LED, kunye nokutshintsha kobushushu bombala omhlophe wokukhanya. Kwi-diode yokukhupha amandla, umsinga wokuqhuba ngokuqhelekileyo ungaphezulu kwamakhulu eemilimitha. Ukuxinana kwangoku kweqhina le-PN kuphezulu kakhulu, ngoko ke ukunyuka kweqondo lokushisa kwe-PN knot kubonakala kakhulu. Ukupakishwa kunye nokusetyenziswa, indlela yokunciphisa ukuxhathisa kwe-thermal yemveliso, ukwenzela ukuba ubushushu obuvezwe ngeqhina le-PN bunokukhutshwa ngokukhawuleza, olungenakuphucula kuphela ukutshatyalaliswa kwangoku kwemveliso, ukuphucula ukukhanya kokukhanya. imveliso, kodwa nokuphucula ukuthembeka kunye nobomi bemveliso. Ukuze kuncitshiswe ukuxhathisa kwe-thermal yemveliso, ukukhethwa kwezinto zokupakisha kubaluleke kakhulu, kubandakanywa ukutshisa ukushisa, ukunamathela, njl. Ukumelana nokushisa kwempahla nganye kufuneka kube phantsi, oko kukuthi, ukusebenza kokushisa ukufudumala kulungile. Okwesibini, uyilo lwesakhiwo kufuneka lube nengqiqo. I-conductivity ye-thermal phakathi kwezinto nganye ihambelana ngokuqhubekayo, kwaye i-thermal conductivity phakathi kwezinto eziphathekayo ilungile ukuphepha ukuvelisa i-bottlenecks yokutshatyalaliswa kobushushu kwi-conductivity ye-thermal. Ngexesha elifanayo, kuyimfuneko ukuqinisekisa ukusuka kubugcisa, ukushisa kukhishwa ngexesha ngokuhambelana nomjelo owenziwe ngaphambili wokutshatyalaliswa kobushushu. 2. Ukhetho lokuzalisa iglue Ngokomthetho wokuchaswa, xa ukukhanya kusenzeka kwimidiya yokukhanya ukuya kukukhanya kwe-sparse medium, xa i-angle yesiganeko ifikelela kwixabiso elithile, oko kukuthi, xa i-angle ebaluleke kakhulu inkulu kune-angle ebalulekileyo, uphehlelelo olupheleleyo luya kwenzeka. Ngokubhekiselele kwi-chip ye-GAN eluhlaza okwesibhakabhaka, isalathisi se-refractive sezinto ze-GAN yi-2.3. Xa ukukhanya kudubula ukusuka kwikristale ukuya emoyeni, ngokomthetho wokuhlanjululwa, i-angle ebalulekileyo 0 = isono-(n2 / n1) yi-Index ye-refractive index, i-N1 yi-index refractive ye-GAN, ngaloo ndlela ibala i-angle ebalulekileyo 0. malunga nama-25.8 degrees. Kule meko, kuphela i-angle yesiganeko i-25.8 degrees kwikona ye-dimensional ye-three-dimensional yesithuba kwikona ye-three-dimensional ye-space ibikwa. Okwangoku, ukusebenza kwe-quantum yangaphandle ye-chip ye-GAN malunga ne-30% -40%. Ngoko ke, ngenxa yokufakwa kwangaphakathi kwe-chip crystal absorption, Umlinganiselo wokukhanya ukuya ngaphandle kwe-crystal uncinci kakhulu. Ngokweengxelo, ukusebenza kwe-quantum yangaphandle ye-chip ye-GAN okwangoku ijikeleze i-30% -40%. Ngokufanayo, ukukhanya okukhutshwa yi-chip kufuneka kudluliselwe kwisithuba ngokusebenzisa izinto zokupakisha, kwaye umphumo wezinto eziphathekayo ekukhanyeni kokukhanya kwezinto kufuneka ziqwalaselwe. Ngoko ke, ukuze kuphuculwe ukukhanya kokukhanya kwe-AC-free LED iimveliso zokupakisha, ixabiso le-N2 kufuneka linyuswe, oko kukuthi, isalathiso se-refractive sezinto zokupakisha ukuphucula i-angle ebalulekileyo yemveliso, ngaloo ndlela kuphuculwe ukukhanya kwemveliso yokupakisha. ukusebenza kakuhle. Ngexesha elifanayo, ukuxutywa kwezinto zokukhanyisa izinto zokupakisha kufuneka kube kuncinci. Ukuze ukwandise umlinganiselo wokukhanya ngaphandle kokukhanya, imilo yokupakisha i-arched okanye i-hemispherical. Ngale ndlela, xa ukukhanya kudutyulwe ukusuka kwizinto zokupakisha ukuya emoyeni, kuphantse kwadutyulwa ngokuthe nkqo kwi-interface, ngoko ke akukho mbonakaliso ipheleleyo iya kuveliswa. 3. Kukho imiba emibini ephambili yonyango lokubonisa unyango. Enye ibonakaliso yonyango ngaphakathi kwe-chip, kwaye enye yimbonakaliso yezinto zokupakisha ekukhanyeni. Ngokubonakaliswa kwangaphakathi nangaphandle, kuya kwandisa umlinganiselo we-optical pass ukusuka ngaphakathi kwe-chip, ukunciphisa Ukufakwa kwangaphakathi kwe-chip, ukuphucula amandla e-AC-free LED egqityiweyo imveliso yokukhanyisa ukukhanya. Ngokuphathelele ukupakishwa, ii-LED zohlobo lwamandla zihlala zidibanisa amandla-uhlobo lwe-chip kwisibiyeli sesinyithi okanye i-substrate ene-cavity ekhanyayo. I-bracket-type reflex cavity ngokubanzi isebenzisa i-electroplating ukuphucula umphumo wokubonakalisa. Iindlela, unyango lwe-electroplating luyenziwa, kodwa ezi ndlela zimbini zingasentla zichaphazelekayo ngokuchaneka kwesikhunta kunye nenkqubo. Okwangoku, i-reflex cavity yasekhaya yohlobo lwe-sheet-type, ngenxa yokungachaneki ngokwaneleyo kokupolisha okanye i-oxidation ye-coating yesinyithi, umphumo we-reflex ubi kakhulu, obangele ukuba ukukhanya okuninzi kufakwe emva kokuba indawo yokubonisa ikhutshiwe, kwaye iyancipha. ayinakubonakaliswa kumgangatho wokukhanya kwithagethi elindelekileyo, nto leyo ekhokelela ekufikeleleni ekufikeleleni kwithagethi elindelekileyo, nto leyo ekhokelela ekufikeleleni ekufikeleleni kwithagethi elindelekileyo, nto leyo ekhokelela ekufikeleleni ekufikeleleni kwithagethi elindelekileyo. okukhokelela ekufikeleleni ekufikeleleni ekufikeleleni ekujoliswe kuko okulindelweyo, okukhokelela ekufikeleleni ekufikeleleni ekufikeleleni ekujoliswe kuyo, okukhokelela ekufikeleleni ekufikeleleni ekujoliswe kuyo, okukhokelela ekufikeleleni ekujoliswe kuyo. ekujoliswe kuko okulindelweyo, kuya kukhokelela ekufikeleleni ekufikeleleni ekufikeleleni ukufikelela Ukukhanya kokukhanyisa emva kokuba ukupakishwa kuphantsi. Siye saqulunqa inkqubo yonyango lwe-reflex kunye ne-organic material yokwambathisa ngamalungelo azimeleyo epropathi enomgangatho ophezulu wokuqonda kunye nepropathi ezimeleyo yengqondo emva kophando oluninzi kunye nemifuniselo. Ukukhanya okudutyulwe ngaphezulu kwayo kubonakalisa ukuphuma kokukhanya. Ukusebenza kakuhle kwemveliso emva kokulungiswa kunokunyuswa ngama-30% -50% xa kuthelekiswa nokusetyenzwa. Isiphumo sokukhanya kwe-1W yethu yangoku yamandla okukhanya okumhlophe kwe-LED inokufikelela kwi-40-50LM / W (iziphumo zovavanyo kumgama we-PMS-50 isixhobo sovavanyo lokuhlalutya i-spectrum), kwaye sifumene isiphumo esihle sokupakisha. 4. Ngokubhekiselele kumandla amhlophe i-AC-free LED, ukuphuculwa kwamandla okukhanya kwe-AC kuhambelana nokukhethwa kunye nokulungiswa kwenkqubo ye-fluorescent powder. Ukuze kuphuculwe ukusebenza kakuhle komgubo we-fluorescent ukuvuselela i-chip eluhlaza okwesibhakabhaka, okokuqala, ukhetho lwe-fluorescent powder kufuneka lufaneleke, kubandakanywa ubude be-wavelength, ubukhulu be-particle kunye nokusebenza kakuhle kokuphefumlelwa.
