Inkinga Yokushabalalisa Ukushisa Yokugqama Okuphakeme Kobuhlalu Belambu Le-LED

Ngokuqiniswa kokuntuleka kwamandla emhlabeni jikelele kanye nezindaba zokwenziwa zasemini, ukukhanya kwe-LED okonga amandla nokuvikelwa kwemvelo nokuthembeka okuphezulu kuya ngokuya kwaziswa inani elikhulu. Ngokuvamile, amalambu e-LED adalwe yimithombo yokukhanya ye-LED akhiwe nge-LED, isakhiwo sokushabalalisa ukushisa, umshayeli, namalensi. Njengamanje, ukuchithwa kokushisa kokukhanya okuphezulu kobuhlalu besibani se-LED emakethe kuvame ukusebenzisa ukuchithwa kokushisa kwemvelo ngemiphumela engagculisi. Umphumela awulungile. Ngokwezinga elithile, kuthinta nokuphila kwesibani. Ukwelashwa kokushisa kuyinkinga enkulu ekusetshenzisweni kokukhanya okuphezulu kwezibani ze-LED ubuhlalu. Ngenxa yokuthi i-nitrogen yesizwe esimise okwe-P ye-nitrogen yesizwe ikhawulelwe yizinga lokuncibilika le-MG namandla okuqalisa aphezulu ephuzu lokutshopa, ukushisa kulula kakhulu ukukhiqiza endaweni emise okwe-P. Indlela yokukhipha ukushisa yamadivayisi we-LED isibani ngokuyinhloko i-thermal conductivity kanye nokushisa -ukugeleza; izinga lomhlahlandlela wokushisa wezinto eziphansi kakhulu ze-substrate ye-SAPPHIRE izokwandisa ukumelana nokushisa kwedivayisi, ikhiqize umphumela omkhulu wokuzifudumeza. Umphumela wamakholori ekukhanyeni okuphezulu kwe-LED mkhulu kakhulu. Ama-calories agxilwe kuma-chips amancane. Izinga lokushisa le-chip liyakhuphuka, libangele ukusatshalaliswa okungajwayelekile kokucindezeleka okushisayo, ukusebenza kahle kokukhanyisa kwe-chip, kanye nokusebenza kahle kwe-fluorescent powder sprint; Uma inani elithile, ukuphazamiseka kwedivayisi kukhushulwa ngemithetho yenkomba. Izibalo zibonisa ukuthi izinga lokushisa lengxenye likhuphuka ngo-2 C, futhi ukwethembeka kunciphisa ngo-10%. Lapho amalungiselelo amaningi e-LED -dense enza uhlelo lokukhanyisa ukukhanya okumhlophe, inkinga yokuhlakazwa kwama-calories ibucayi kakhulu. Ukuxazulula inkinga yokuphathwa kokushisa sekuyisidingo sokuqala sokukhanya okuphezulu kwezicelo zobuhlalu besibani se-LED. Ubudlelwano phakathi kosayizi nokuchithwa kokushisa kwe-chip abukwazi ukuzitshwa. Indlela eqondile yokwandisa ukukhanya kwamandla e-LED ukukhulisa amandla okufaka. Ukuze uvimbele ukugcwaliswa kwesendlalelo somthombo, usayizi wefindo le-P-N kufanele ukhuliswe ngokufanele; ukwanda kwamandla okufaka kumele kwenze ifindo. Khulisa izinga lokushisa, bese wehlisa ukusebenza kahle kwe-quantum. Ukuthuthukiswa kwamandla epayipi elilodwa kuncike ekhonweni ledivayisi lokuqondisa ukushisa okuvela ku-P-N ukuze kugcinwe into ekhona ye-chip, isakhiwo, inqubo yokupakisha, ukuminyana kwamanje kwezimo zamanje, nezimo ezifanayo zokukhipha ukushisa. Izinga lokushisa lizoqhubeka nokukhuphuka. Inkinga yokushisa kokushisa kwezibani ze-LED ubuhlalu ihlobene eduze nezici eziningi. Ukuze kunwetshwe impilo yesevisi yobuhlalu besibani se-LED futhi kuthuthukiswe ukwethembeka, ukucatshangelwa okuphelele kuyadingeka. Ngaphansi kwesisekelo sokuqinisekisa ukukhanya kanye nemiphumela yokukhanyisa.
