Umzimba wesibane sokuhlobisa i-LED awuvelisi imisebe ye-ultraviolet

I-LED eyodwa yamandla ityhubhu i-0.03 ~ 0.06 watts, usebenzisa i-DC drive, i-tube eyodwa yokuqhuba i-voltage 1.5 ~ 3.5 volts, yangoku i-15 ~ 18 mA, impendulo ekhawulezayo, inokusebenza kwi-frequency ephezulu. Ngaphantsi kwemeko yokukhanya okufanayo kwezibane zokuhombisa ze-LED, ukusetyenziswa kwamandla kukwishumi lamawaka lee-incandescent bulbs, kunye nesiqingatha seso se-fluorescent tubes. Kuqikelelwa eJapan ukuba ii-LED ezinokukhanya okuphindwe kabini zisetyenziselwa ukubuyisela isiqingatha seebhalbhu zaseJapan. Izibane ze-incandescent kunye ne-fluorescent. Imali elingana ne-6 yeebhiliyoni zeelitha ze-oyile ekrwada inokongiwa ngonyaka. Kwimeko yezibane zokugada ibhulorho, isibane sefluorescent esinesiphumo esifanayo singaphezulu kwe-40 watts, ngelixa amandla e-LED nganye angama-watts ayi-8 kuphela, kwaye inokuba nemibala.

Izibane zokuhombisa ze-LED zeprojekthi yokuhlobisa umnyhadala zisebenzisa i-radiation ye-electronic light field lighting, kwaye iifilaments zineziphene ezifana nokutshisa okulula, ukufakwa kobushushu, kunye nokunciphisa ukukhanya. Isibane se-LED sincinci ngobukhulu kwaye silula ngobunzima, sifakwe kwi-epoxy resin, sinokumelana nokutshatyalaliswa komatshini kunye nokungcangcazela, kwaye akulula ukuphuka. Ubomi obuqhelekileyo ziiyure ezingama-100,000. Ubomi benkonzo yomthendeleko we-LED isibane sokuhlobisa umzimba unokufikelela kwi-5-10 iminyaka, enokunciphisa kakhulu iindleko zokugcinwa kwesibane kunye nokuphepha intlungu yokutshintshwa kwesibane rhoqo.

Umzimba weholide ye-LED ukukhanya okuhombisayo akuvelisi imitha ye-ultraviolet, ngoko ke akuyi kubakho iingcongconi ezininzi malunga nomthombo wokukhanya njengezibane zendabuko. Izibane zemveli zikhanyiswa yi-voltage ephezulu ekhutshwe yi-rectifier, kwaye ayikwazi ukukhanyiswa xa i-voltage iyancipha. Umzimba wesibane sokuhlobisa iholide unokukhanyiswa ngaphakathi koluhlu oluthile lombane, kwaye ukukhanya kunokulungiswa kwakhona.

Iichips ze-LED zeeholide ze-LED izibane zokuhombisa ziya kuguga ngokuqinisekileyo ngexesha lenkqubo yokukhanyisa, kwaye ke ukukhanya kuyabola. Ngokuqhelekileyo, emva kwexesha lokusetyenziswa, izibane ngokuqinisekileyo ziya kuba mnyama kancinci kunokuqala, kwaye ukubola kokukhanya okuphantsi kunokuqinisekisa ubomi obude. Kwiqondo lokushisa eliphezulu le-junction, ukubola kokukhanya kwe-LED kuya kukhula ngokuthe ngcembe njengoko ubushushu bunyuka. Nje ukuba ubushushu bangaphakathi be-LED bugqithise ubushushu besiphambuka, ukubola kokukhanya kuya kwanda kumgca othe ngqo.

Ukusebenza okuphezulu okukhanyayo kuya kunciphisa ukuveliswa kobushushu, kwaye ukunciphisa ukuveliswa kobushushu kunokunciphisa ukubola kokukhanya, kwaye ubushushu obuphezulu besiphambuka buya kunciphisa iimfuno zeeradiyetha. Ukukhetha iitshiphusi zodidi oluphezulu ngowona mnyhadala ubalaseleyo wokukhanya kwe-LED. Nangona kunjalo, izibane ezinama-American CREE chips azikwazi ukuthengwa kubuncwane obuthile, kuba zibiza kakhulu, kwaye isithuba phakathi kwee-chips zobukhulu obufanayo malunga namaxesha angama-10-100, kwaye umsantsa phakathi kweemveliso ezigqityiweyo ukhulu ngakumbi.
