Imiba Emithathu Engundoqo Yezibane ze-LED eneneni zichaphazela uMgangatho wezibane ze-LED

Izinto ezintathu ezibalulekileyo zezibane ze-LED ziye zachaphazela kakhulu umgangatho wezibane ze-LED. Makhe sijonge izizathu ezineenkcukacha kunye: idatha efunyenwe yintsimbi yesibane esisodwa se-LED kwibhodi yokuguga, kwaye yahlanganisa amaso isibane se-LED ibe yinto enye. . Ubungakanani balo mahluko buxhomekeke kwiiparamitha zombane kunye noyilo lwezibane ngexesha lomsebenzi we-LED, kunye nokusingqongileyo okusetyenziswe zizibane. 1. Umgangatho wezibane ze-LED zezibane zezibane ze-LED yinto ebalulekileyo. Ngokomzekelo, okufanayo kuboniswa yi-chip ye-chip ye-14mil ye-chip, kunye nezibane zesibane se-LED ezifakwe kwi-gum ephantsi kunye neglue emhlophe kunye neglue yokupakisha eyenziwe nge-epoxy resin eqhelekileyo, elayita enye kwindawo engama-30. izidanga. Emva kwamawaka eeyure, idatha encitshisiweyo yi-70% yokubola kwe-optical; ukuba i-D yohlobo lwe-D ephantsi-i-glue ebolileyo ifakwe kwi-encapsulated, kwindawo efanayo yokuguga, i-1,000-hour light decay yi-45%; , 1,000-iyure ukubola ukukhanya 12%; ukuba udidi lwe-B lufakwe kwi-glue ephantsi yokunciphisa, kwindawo efanayo yokuguga, amawaka eeyure zokubola kokukhanya kwe--3%; ukuba i-Class A i-low-declining glue, kwindawo efanayo yokuguga, amawaka eeyure zokukhanya kwindawo efanayo yokuguga, amawaka eeyure zokukhanya kwindawo efanayo yokuguga, amawaka eeyure zokukhanya kwindawo efanayo yokuguga, amawaka iiyure zokukhanya kwindawo efanayo yokwaluphala, amawaka eeyure zokukhanya ngamawaka eeyure zokukhanya. Uthini umahluko phakathi kokubola kwe -6%. Kutheni le nto inkqubo yokupakishwa eyahlukileyo ibangela umahluko omkhulu? Esinye sezizathu ezibalulekileyo kukuba i-chip ye-LED iyoyika ubushushu. Ngamanye amaxesha kushushu ngaphezu kwekhulu leedigri ngexesha elifutshane, kwaye impembelelo ayinkulu. Ndiyoyika ukuba kuya kuba kwiqondo lokushisa eliphezulu ixesha elide. Ingumonakalo omkhulu kwi-chip ye-LED. Ngokuqhelekileyo, i-thermal conductivity ye-epoxy resins eqhelekileyo incinci. Ke ngoko, xa iitshiphusi ze-LED zilayitiwe, iitshiphusi ze-LED kufuneka zikhuphe ubushushu, kwaye i-epoxy resin conductivity eqhelekileyo ye-thermal conductivity ilinganiselwe. Xa ubushushu besibiyeli se-LED bungama-45 degrees, ubushushu beziko le-chip kwi-bead yesibane se-LED linokugqithisa ama-80 degrees. Iqondo lokushisa le-LED liyi-80 degrees ngokwenene, ngoko xa i-chip ye-LED isebenza kwiqondo lokushisa lobushushu, ibuhlungu kakhulu, ekhawulezisa ukuguga kwemithombo yokukhanya ye-LED. Xa i-chip ye-LED isebenza, ubushushu beziko buvelisa ubushushu obuphezulu be-100 degrees. Ingasebenzisa ngokukhawuleza iphini yokuma ekushiseni ukunciphisa ubushushu, ngaloo ndlela inciphisa umonakalo kuyo. Ke ngoko, xa ubushushu besibane se-LED bungamadigri angama-60, ubushushu beziko le-chip lunokuba ngama-61 degrees nje. Njengoko kunokubonwa kwidatha engentla, izibane zesibane se-LED ezikhetha ukuba luhlobo luni lwenkqubo yokupakisha ekhethiweyo, kwaye isigqibo esikhanyayo sezibane ze-LED sinquma ngokuthe ngqo isigqibo sokukhanya kwezibane ze-LED. 2. Ubume kunye nobushushu bomsebenzi wokukhanya kwe-LED Ngokwedatha yomthombo omnye wokukhanya kwe-LED, ukuba umthombo wokukhanya we-LED unomsebenzi omnye wokukhanyisa, kwangaxeshanye, ubushushu bendalo obukhoyo bungama-30 degrees, ke i-LED enye. umsebenzi womthombo wokukhanya uyasebenza Ukushisa kweshelufu akuyi kudlula i-45 degrees. Ngeli xesha, ubomi bale LED buya kulunga. Ukuba kukho i-100 yemithombo yokukhanya ye-LED emsebenzini ngexesha elifanayo, ikhefu phakathi kwabo yi-11.4mm kuphela, ngoko ubushushu besibiyeli somthombo wokukhanya we-LED malunga nemfumba yesibane ayinakudlula i-45 degrees, kodwa ezo LED ziphakathi iimfumba zezibane aziyi Umthombo wokukhanya unokufikelela kuma-degrees angama-65 aphezulu. Ngeli xesha, umthombo wokukhanya kwe-LED luvavanyo. Emva koko, loo mithombo yokukhanya ye-LED iqokelelwe embindini iya kuthiyori ngokukhawuleza, kwaye imithombo yokukhanya ye-LED ejikeleze imfumba yesibane iya kucotha. Kodwa ukuba izibane zesibane se-LED zingaphezulu kwe-25mm ngaphandle, ke iikhalori abaziphambukisayo aziyi kuqokelelwa kakhulu. Ngeli xesha, ubushushu bezibane ze-LED nganye kufuneka zibe ngaphantsi kwama-degrees angama-50, nto leyo ehambelana nomsebenzi oqhelekileyo we-LED. Ukuba indawo yomsebenzi we-LED ikwindawo ebanda kakhulu, ubushushu obuqhelekileyo bonyaka wonke bunokuba malunga nama-degrees angama-15 okanye amancinci, ngoko kwi-LED, ixesha lokuphila lide. Okanye, xa i-LED isebenza, kukho ifeni encinci ecaleni kwayo kwaye iyincede ukususa ubushushu. Oku kuya kunceda kwakhona ubomi be-LED. Wonke umntu kufuneka azi ukuba izibane ze-LED zoyika ubushushu. Ukuphakama kweqondo lobushushu, bufutshane ubomi be-LED, iyancipha iqondo lobushushu, kwaye ubude be-LED ubomi. Ubushushu obusebenzayo be-LED efanelekileyo buphakathi kwe-5 okanye i-zero degrees negative. Kodwa oku akunakwenzeka. Ngoko ke, emva kokuba siqonde iiparamitha ezifanelekileyo zokusebenza kwezibane zesibane se-LED, kufuneka someleze umsebenzi wokuqhuba ubushushu kunye nokutshatyalaliswa kobushushu xa kuyilwa izibane kangangoko kunokwenzeka xa kuyilwa izibane kangangoko kunokwenzeka. Ngapha koko, okukhona iqondo lobushushu lisezantsi, kokukhona ubude bobomi be-LED. Okwesithathu, uyilo olusebenzayo lweparamitha yombane yeentsimbi zesibane se-LED Ngokweziphumo zovavanyo, ukuthoba ukukhanya okumhlophe kwe-LED, kuncinci ubushushu obuphumayo, ngokuqinisekileyo, buncinci ukuqaqamba. Ngokutsho kophando, ukuyila kwesiphaluka sokukhanyisa ukukhanya kwe-LED, umqhubi wangoku we-LED ngokuqhelekileyo ngu-5-10mA kuphela; inani elikhulu izibane ezisetyenziswa izibane, ezifana ngaphezu 500 okanye ngaphezulu Kwaye ngokubanzi ethandwa LED izibane isicelo isibane sokuqhuba langoku kuphela 15-18mA, kwaye abantu abambalwa bayilwe yangoku ukuya ngaphezu 20mA. Iziphumo zovavanyo zibonise kwakhona ukuba phantsi komqhubi wangoku we-14mA, kwaye isiciko asizange singene umoya, ubushushu bomoya kuyo bufikelele kwi-71 degrees, iimveliso eziphantsi zokwehla, i-1,000 yeyure yokubola kokukhanya, iiyure ezingama-2000 zokubola kokukhanya kwe-3% ukuya kwi-3% , 3% ukubola yi-3%. Oku kubonisa ukuba oku kuphantsi-kwehla ukukhanya okumhlophe kwe-LED kufikelele ekusetyenzisweni kwayo okuphezulu kwindawo enjalo. Nokuba ingakanani na, ingumonakalo kuyo. Ngenxa yokuba ibhodi yokuguga esetyenzisiweyo ayinawo umsebenzi wokutshatyalaliswa kobushushu, ukushisa okwenziwa ngexesha le-LED ngokusisiseko akukwazi ukuyihambisa ngaphandle. Uvavanyo lwabonisa oku. Ubushushu bomoya kwiphaneli endala ifikelele kwiqondo lokushisa eliphezulu le-101 degrees. Ubushushu obuphezulu besiciko kwipaneli endala ngama-degrees angama-53 kuphela, ngamaqondo amaninzi. Oku kubonisa ukuba isiciko seplastiki esenziwe ngokusisiseko asinawo umsebenzi wokuqhuba ubushushu kunye nokuchithwa kobushushu. Kodwa kuyilo lwesibane ngokubanzi, ngokuqwalasela umsebenzi wokuqhuba ukushisa nokushisa. Ngoko ke, isishwankathelo, ukuyila kweeparamitha zombane ezisebenzayo zezibane ze-LED kufuneka zisekelwe kwimeko yangempela. Ukuba ubushushu -ukuqhuba umsebenzi wokutshatyalaliswa kwesibane kulungile kakhulu, kulungile ukunyusa ukuqhubela phambili kwezibane ezimhlophe ze-LED, kuba amaso wesibane se-LED asebenza ukuvelisa. Ubushushu bunokuthunyelwa ngaphandle kwexesha, kwaye akukho monakalo kwi-LED, eyona nto ilungileyo yokunyamekela kwe-LED. Ngokuchasene noko, ukuba umsebenzi wokufudumeza kunye nokushisa kwesibane u-sloppy, kungcono ukuyila isekethe encinci kwaye uyivumele ibeke ubushushu.
