Litsela tsa ho rarolla mocheso oa mocheso oa LED
3. 1 Khetho ea substrate e nang le conductivity e ntle ea mocheso
Khetha li-substrates tse nang le conductivity e ntle ea mocheso, tse kang Al-based metal core printed circuit boards (MCPCBs), ceramics, le composite metal substrates, ho potlakisa ho qhala ha mocheso ho tloha epitaxial layer ho ea substrate ea mocheso oa mocheso. Ka ho ntlafatsa moralo oa mocheso oa boto ea MCPCB, kapa ho kopanya li-ceramics ka kotloloho ho karolo ea tšepe ea tšepe ho theha substrate e thehiloeng ka tšepe e nang le mocheso o tlase oa sintered ceramic (LTCC2M), substrate e nang le conductivity e ntle ea mocheso le coefficient e nyane ea katoloso ea mocheso e ka fumanoa. .
3.2 Ho lokolloa ha mocheso holim'a substrate
E le ho jala mocheso holim'a substrate ho tikoloho e potolohileng ka potlako, hona joale, lisebelisoa tsa tšepe tse nang le conductivity e ntle ea mocheso tse kang Al le Cu li atisa ho sebelisoa e le mocheso oa mocheso, 'me ho qobelloa ho pholisa ho kang li-fan le liphaephe tsa mocheso oa loop li kenngoa. Ho sa tsotellehe litšenyehelo kapa ponahalo, lisebelisoa tse pholileng tsa ka ntle ha lia lokela ho khantša LED. Ka hona, ho ea ka molao oa paballo ea matla, tšebeliso ea li-ceramics tsa piezoelectric e le sekoti sa mocheso ho fetola mocheso hore e be ho sisinyeha le ho sebelisa matla a mocheso ka kotloloho e tla fetoha e 'ngoe ea lintho tse tla tsepamisoa maikutlo liphuputsong tse tlang.
3.3 Mokhoa oa ho fokotsa ho hanyetsa mocheso
Bakeng sa lisebelisoa tsa LED tse nang le matla a phahameng, kakaretso ea ho hanyetsa mocheso ke kakaretso ea likhanyetso tsa mocheso oa lithapo tse 'maloa tsa mocheso tseleng ea mocheso ho tloha pn junction ho ea tikolohong e ka ntle, ho kenyelletsa le mocheso o ka hare oa mocheso oa mocheso oa mocheso oa LED ka boeona le mocheso o ka hare. teba ho boto ea PCB. Ho hanyetsa mocheso oa sekhomaretsi se tsamaisang mocheso, ho hanyetsa mocheso oa sekhomaretsi sa thermally conductive pakeng tsa PCB le sekoahelo sa mocheso se ka ntle, le ho hanyetsa mocheso oa mocheso o ka ntle oa mocheso, joalo-joalo, mocheso o mong le o mong oa mocheso oa potoloho o tla etsa hore ho be le tse itseng. litšitiso tsa phetiso ea mocheso. Ka lebaka leo, ho fokotsa palo ea ka hare mocheso sinks le ho sebelisa tshebetso tšesaane filimi ho hlahisa ka ho toba segokanyimmediamentsi sa sebolokigolo eleketrode sinks mocheso le dikarolo insulation ka tšepe mocheso teba ka haholo fokotsa kakaretso mogote ho hanyetsa. Theknoloji ena e ka fetoha LED e matla haholo nakong e tlang. Tsela e tloaelehileng ea sephutheloana sa ho senya mocheso.
3.4 Kamano pakeng tsa ho hanyetsa mocheso le mocha oa ho senya mocheso
Sebelisa mocha o mokhuts'oane oa ho qhala mocheso. Ha mocha oa ho qhala mocheso o lelelele, o na le matla a mangata a ho hanyetsa mocheso le monyetla o moholo oa ho thibela mocheso.
