Imiba emininzi ekufuneka uyiqaphele kuyilo lwezibane ze-LED zangaphandle
1.Abaqulunqi bezibane zangaphandle kufuneka baqwalasele indawo yokusebenza yezibane ze-LED zangaphandle
Ngenxa yendawo enzima yokusebenza, izibane ze-LED zangaphandle zichaphazeleka kwiimeko zendalo ezifana nokushisa, ukukhanya kwe-ultraviolet, umswakama, imvula, imvula, isanti, igesi yeekhemikhali, njl. Emva kwexesha, ingxaki yokubola kokukhanya kwe-LED inzulu. Ngoko ke, abaqulunqi bezibane zangaphandle kufuneka baqwalasele impembelelo yale miba yangaphandle yokusingqongileyo ekukhanyeni kwangaphandle kwe-LED xa kuyilwa.
2. Yintoni ekufuneka ihlawulwe ingqwalasela ekukhethweni kwezinto zokutshatyalaliswa kobushushu kwizibane ze-LED zangaphandle
I-casing yangaphandle kunye ne-heat sink yenzelwe ukudibanisa ukusombulula ingxaki yokuvelisa ukushisa kwe-LED. Le ndlela ikhethwayo, kwaye i-aluminium okanye i-aluminium alloy, i-copper okanye i-alloy yobhedu, kunye nezinye i-alloys ezine-conductivity efanelekileyo yokushisa zisetyenziswa ngokubanzi. Ukutshatyalaliswa kobushushu kunokutshatyalaliswa kobushushu be-air convection, umoya onamandla wokupholisa ubushushu kunye nokuchithwa kobushushu bombhobho wobushushu. (I-Jet yokupholisa ubushushu bokutshatyalaliswa luhlobo lokupholisa umbhobho wobushushu, kodwa isakhiwo sinzima ngakumbi.)
3. Iteknoloji yokupakisha i-chip ye-LED yangaphandle
Okwangoku, izibane ze-LED (ikakhulukazi izibane zesitalato) eziveliswe e-China zihlanganiswa kakhulu ngokusebenzisa ii-LED ze-1W kwiintambo ezininzi kunye nokuhambelana. Le ndlela inokumelana ne-thermal ephezulu kuneteknoloji yokupakisha ephezulu, kwaye akukho lula ukuvelisa izibane eziphezulu. Okanye inokuhlanganiswa kunye ne-30W, i-50W okanye iimodyuli ezinkulu ukufezekisa amandla afunekayo. Izinto zokupakisha zezi LED zifakwe kwi-epoxy resin kwaye zifakwe kwi-silicone. Umahluko phakathi kwezi zimbini kukuba iphakheji ye-epoxy resin inokumelana nobushushu obuphantsi kwaye ithanda ukuguga ngokuhamba kwexesha. Iphakheji ye-silicone ingcono ekuchaseni ukushisa kwaye kufuneka ikhethwe xa usebenzisa.
Kungcono ukusebenzisa i-multi-chip kunye nesinki yobushushu njengephakheji epheleleyo, okanye ukusebenzisa i-aluminium substrate multi-chip package kwaye emva koko udibanise izinto zokutshintsha isigaba okanye igrisi ekhupha ubushushu kwi-sinki yobushushu, kunye nokumelana nokushisa. imveliso iphezulu kunaleyo yemveliso edityaniswe nesixhobo se-LED. Ngaphantsi kweyodwa ukuya kweyesibini ukuxhathisa kwe-thermal, okulungele ngakumbi ukutshatyalaliswa kobushushu. Kwimodyuli ye-LED, i-modyuli yemodyuli ngokubanzi i-substrate yobhedu, kwaye uxhulumaniso kunye ne-sink yokushisa yangaphandle kukusebenzisa isixhobo esihle sokutshintsha isigaba, okanye igrisi elungileyo yokutshatyalaliswa kobushushu ukuqinisekisa ukuba ubushushu kwi-substrate yobhedu bunokudluliselwa ukutshona kobushushu bangaphandle ngexesha. Ukunyuka, ukuba ukucutshungulwa akulunganga, kuya kubangela ngokulula ukuqokelelwa kobushushu kubangele ukuba ubushushu bemodyuli chip bunyuke kakhulu, nto leyo eya kuchaphazela ukusebenza okuqhelekileyo kwe-chip ye-LED. Umbhali ukholelwa ukuba: iphakheji ye-multi-chip ifanelekile ukuveliswa kwezixhobo zokukhanyisa ngokubanzi, ukupakishwa kwemodyuli ifanelekile kwithuba elilinganiselweyo lokuvelisa izibane ezikhokelwayo (ezifana nezibane eziphambili zokukhanyisa iimoto, njl.).
I-4.Uphando malunga noyilo lwe-radiator yesibane se-LED yangaphandle yinxalenye ebalulekileyo yesibane se-LED. Ubume bayo, umthamo kunye nommandla wokutshatyalaliswa kobushushu kufuneka ulungiselelwe ukuba ube luncedo. I-radiator incinci kakhulu, ubushushu obusebenzayo besibane se-LED buphezulu kakhulu, buchaphazela ukusebenza kakuhle okuLuminous kunye nokuphila ixesha elide, ukuba i-radiator inkulu kakhulu, ukusetyenziswa kwezixhobo kuya kwandisa iindleko kunye nobunzima bemveliso, kunye nokukhuphisana kwemveliso nciphisa. Kubalulekile ukuyila i-radiator yokukhanya kwe-LED efanelekileyo. Uyilo lwesitya sokushisa sinezi ndawo zilandelayo:
1.Ukuchaza amandla ukuba izibane ze-LED kufuneka zichithe ubushushu.
I-2.Yila ezinye iiparitha zokushisa ukushisa: ukushisa okuthe ngqo kwetsimbi, i-thermal conductivity yensimbi, ukuchasana kwe-thermal ye-chip, ukunyanzeliswa kwe-thermal ye-heat sink, kunye nokuxhatshazwa kwe-thermal yomoya ojikelezayo.
3.Qinisekisa uhlobo lokusasazwa, (ukupholisa i-convection yendalo, ukupholisa umoya onamandla, ukupholisa umbhobho wobushushu, kunye nezinye iindlela zokutshatyalaliswa kobushushu.) Ukususela kuthelekiso lweendleko: i-convection yendalo yokupholisa indleko ephantsi, isithuba sokupholisa umoya onamandla, iindleko zokupholisa umbhobho wobushushu ziphezulu. , ixabiso lokupholisa ijethi liphezulu .
4. Qinisekisa ubushushu obuphezulu bokusebenza obuvunyelweyo kwizibane ze-LED (ubushushu be-ambient kunye nokunyuka kobushushu obuvunyiweyo be-luminaire)
5.Bala umthamo kunye nokushisa kwendawo yokutshatyalaliswa kobushushu. Kwaye unqume ubume be-heat sink.
6. Hlanganisa i-radiator kunye nesibane se-LED kwi-luminaire epheleleyo, kwaye usebenze kuyo ngaphezu kweeyure ezisibhozo. Jonga iqondo lobushushu le-luminaire kwiqondo lobushushu legumbi le-39 °C - 40 °C ukubona ukuba iimfuno zokuphelisa ubushushu ziyafezekiswa na ukuqinisekisa ukuba ubalo luchanekile. Imiqathango, emva koko ubale kwakhona kwaye ulungelelanise iiparamitha.
7.Itywina leradiyetha kunye nesibane kufuneka zingangeni manzi kwaye zikhuseleke nothuli. I-pad yerabha echasene nokuguga okanye i-silicone yerabha yerabha kufuneka ifakwe phakathi kwesibane sesibane kunye ne-heat sink. Kufuneka ibotshelelwe ngeebholiti zensimbi ezingenasici ukuze kuqinisekiswe ukungenwa kwamanzi kunye nothuli. Imicimbi, ngokubhekiselele kubugcisa obukhanyisayo bangaphandle obubhengezwe yi-China, kunye nemigangatho yoyilo lwezibane zendlela yasezidolophini, olu lulwazi olubalulekileyo lwabayili bezibane zangaphandle.
