Maboto a Potoloho a LED
Lefapheng la dieleketeroniki, phetoho ya theknoloji e lebisitse ho thehweng ha disebediswa tse ngata tsa elektroniki, ho kenyeletswa le di-PCB tse entsweng ka ho kgetheha bakeng sa tshebediso ya di-diode tse ntshang lesedi (di-LED). Diboto tsa potoloho ya LED di bontsha boqapi bona. Diboto tsena di bapala karolo ya bohlokwa maboneng a LED , moo chip ya LED e hokahaneng ka ho toba le boto ya potoloho, eo, ka lehlakoreng le leng, e hoketsweng sinkeng ya mocheso o futhumetseng bakeng sa ho qhala mocheso ka katleho.
Ho utloisisa Maboto a Potoloho ea LED
Li-LED ke li-semiconductor diode tse hlahisang leseli le bonahalang ha motlakase o feta ho tsona. Libotong tsa potoloho ea LED, chip ea LED e ikarabellang bakeng sa tlhahiso ea leseli e rekisoa holim'a boto, eo hangata e entsoeng ka aluminium, e tsejoang ka thepa ea eona e phahameng ea ho felisa mocheso. Lera le tšesaane la thepa e phahameng ea mocheso oa motlakase oa dielectric e sebelisoa ho boto ea potoloho ea aluminium, ho netefatsa hore mocheso o fetisoa hantle le ho qhalana.
Lilemong tsa morao tjena, ho paka ha disebediswa tse kenngwang hodima metsi ( SMD ) ho atile haholo theknolojing ya LED, e leng se dumellang ho kopanngwa ha di-module tse ngata tsa LED mohloding o le mong wa lesedi. Boto ya potoloho ya LED e sebetsa e le motheo wa motlakase le wa mechini bakeng sa disebediswa tsena tsa semiconductor.

Maboto a Potoloho a LED
Indasteri ea Boto ea Potoloho ea Lebone la Lebone la LED
Li-LED li ntse li tsebahala ka potlako indastering ea mabone ka lebaka la melemo ea tsona e mengata ho feta mabone a tloaelehileng a incandescent. Mabone a mabone a LED a sebelisa liboto tsa potoloho tsa LED ho matlafatsa le ho laola li-diode tse hlahisang leseli, tse nolofalletsang khanya e sebetsang le e tšoarellang nako e telele. Ha ho bapisoa le mabone a incandescent, mabone a LED a fana ka melemo e mengata:
- Ho sebetsa hantle ha motlakase: Mabone a LED a sebelisa matla a fokolang haholo ho feta mabone a tloaelehileng a incandescent, a bakang litšenyehelo tse tlase tsa matla le ho fokotsa tšusumetso ea tikoloho.
- Nako e telele ea Bophelo: Mabone a LED a na le nako e telele ea bophelo ho feta mabone a incandescent, a tšoarella ho fihlela makhetlo a 25 nako e telele. Sena se fokotsa khafetsa ea li-bulbs tse ncha, ho boloka nako le chelete.
- Phallo e Tlase ea Mocheso: Mabone a LED a ntša mocheso o fokolang ho feta mabone a incandescent, a etsa hore a sireletsehe le ho phutholoha ho sebelisoa, haholo-holo libakeng tse koetsoeng.
- Mefuta e fapaneng ea libopeho le boholo: Mabone a LED a fumaneha ka mefuta e mengata ea libopeho le boholo, e lumellang hore ho be le mekhoa e mengata ea mabone le lisebelisoa.
- Ntle le Mercury: Ho fapana le mabone a fluorescent, mabone a LED ha a na mercury, a etsa hore a sireletsehe bakeng sa tikoloho le ho lahla habonolo.
Indasteri ea boto ea lebone la lebone la lebone la LED e ntse e tsoela pele ho ntlafatsa ho ntlafatsa ts'ebetso, ts'ebetso, le litšenyehelo tse tlase tsa tharollo ea mabone a LED. Ka tsoelo-pele e tsoelang pele ea theknoloji ea LED le mekhoa ea tlhahiso, mabone a LED a mothating oa ho ba tharollo ea mabone bakeng sa lisebelisoa tsa bolulo, tsa khoebo le tsa indasteri.
Lintlha Tseo U Lokelang ho li Nahana ka Moralo oa Boto ea Potoloho ea Leseli la LED
Ho rala liboto tsa potoloho ea LED ho hloka ho shebisisa lintlha tse 'maloa ka hloko, ho kenyelletsa khetho ea thepa, taolo ea mocheso, mokhoa oa ho tsamaisa le ho qeta bokaholimo:
- thepa: Liboto tsa potoloho tsa LED hangata li na le setsi sa aluminium bakeng sa ho qhala mocheso hantle. Lera la dielectric, mask a solder, le lera la potoloho ea koporo li beiloe holim'a substrate ea aluminium.
- Taolo ea Thermal: Licheso tsa mocheso le li-cores tsa aluminium li bohlokoa bakeng sa ho qhala mocheso ka katleho libotong tsa potoloho tsa LED, ho netefatsa ts'ebetso e nepahetseng le bophelo bo bolelele.
- Trace Routing: Mesaletsa e entsoeng hantle e thibela lipotoloho tse khutšoane le tšitiso, ho netefatsa likhokahano tse sireletsehileng le ts'ebetso e tšepahalang.
- fihlela qetellong: Qetello ea bokaholimo ba liboto tsa potoloho ea LED e ama ho soasoa le ho kopanya, ka likhetho tse ngata tsa ho qetela tse fumanehang ho latela litlhoko tsa projeke le tekanyetso.
Tsoelo-pele ho Moralo oa Boto ea Potoloho ea Aluminium-LED
Likhatelo-pele tsa morao-rao tsa moralo oa boto ea potoloho ea LED, haholo-holo tse kenyelletsang li-cores tsa aluminium, li fetotse matla a taolo ea mocheso le matla a ho felisa mocheso a lisebelisoa tsa mabone a LED. Likhatelo-pele tsena li nolofalelitse ho kopanngoa ha li-LED tse ngata ho boto e le 'ngoe ea potoloho, e leng se lebisang ho khanya le katleho e ntlafetseng. Ntle le moo, lintlafatso tsena li ntlafalitse taolo ea mocheso, ho netefatsa ts'ebetso e tsitsitseng le nako e telele ea lisebelisoa tsa mabone a LED.
Taolo e Ntlafetseng ea Thermal
Tšebeliso ea li-cores tsa aluminium ho liboto tsa potoloho ea LED e ntlafalitse haholo tsamaiso ea mocheso. Aluminium ke conductor e babatsehang ea mocheso, e lumellang ho qhala hantle ha mocheso o hlahisoang ke li-LED. Sena se thibela ho futhumala ho feteletseng le ho netefatsa ts'ebetso e nepahetseng ea li-LED ka nako e telele.
Phallo ea Mocheso e Matlafalitsoeng
Liboto tsa potoloho tsa LED tse nang le li-cores tsa aluminium li etselitsoe ho felisa mocheso ka katleho ho feta mapolanka a tloaelehileng a potoloho. Sena se finyelloa ka tšebeliso ea lisebelisoa tse khethehileng tsa mocheso le lisebelisoa tse tsamaisang mocheso tse thusang ho fetisetsa mocheso ho tloha ho li-LED le ho ea tikolohong e potolohileng. Sena se fella ka lithempereichara tse pholileng tsa ts'ebetso le ts'ebetso e ntlafetseng.
Ho kopanngoa ha li-LED tse ngata
Matla a ntlafetseng a ho laola mocheso le ho senya mocheso oa liboto tsa potoloho tsa aluminium-LED li entse hore ho khonehe ho kopanya li-LED tse ngata ka boto e le 'ngoe. Sena se lumella maemo a phahameng a khanya le ho ntlafatsa khanya ea leseli, ho etsa hore lisebelisoa tsa mabone a LED li be le mekhoa e mengata le tse sebetsang ka mokhoa o fapaneng oa lisebelisoa.
Tshebetso e tsitsitseng le ho phela halelele
Ka ho laola mocheso ka katleho le ho netefatsa hore mocheso o tsitsitseng oa ts'ebetso, liboto tsa potoloho tsa aluminium-LED li ka fana ka ts'ebetso e tsitsitseng ka nako e telele. Sena se thusa ho eketsa nako ea bophelo ba li-LED le ho fokotsa tlhoko ea tlhokomelo le ho nkeloa sebaka, e leng se fellang ka ho boloka litšenyehelo bakeng sa basebelisi.
Ka kakaretso, tsoelo-pele moralong oa boto ea potoloho ea aluminium-LED e bile le tšusumetso e kholo ho katleho, ts'ebetso le bophelo bo bolelele ba litsamaiso tsa mabone a LED. Tsoelo-pele ena e entse hore mabone a LED a be le mekhoa e mengata, a boloke matla, 'me a be le litšenyehelo tse tlase, e leng se etsang hore e be khetho e ntle bakeng sa mefuta e mengata ea lits'ebetso tsa mabone.

Melemo ea Aluminium Circuit Boards bakeng sa li-LED
Liboto tsa potoloho tsa LED, likarolo tsa bohlokoa tsa mabone a LED, li na le boto ea aluminium e nang le lesela le phahameng la mocheso oa dielectric. Liboto tsena li senya mocheso ka katleho, li netefatsa hore LED e phela nako e telele le ts'ebetso. Li kopane, li bobebe ebile lia tšoarella, 'me li fana ka likhetho tsa ho iketsetsa likopo tse fapaneng. Tsoelo-pele ea liboto tsa potoloho tsa LED tse thehiloeng ka aluminium li ntlafalitse tsamaiso ea mocheso, e leng se etsang hore li be le litšenyehelo tse ngata le ho boloka tikoloho.
Liboto tsena li fumana lits'ebetso ho liindasteri tsa mehala, likoloi, likhomphutha le indastering ea bongaka. Liphephetso tse kang taolo ea mocheso le botsitso ba mebala li teng, tse hlokang ho nahanoa ka mokhoa o hlokolosi oa moralo. Lintlha tse kang khetho ea thepa, tsamaiso ea mocheso, litsela tsa morao-rao, le qetello ea bokaholimo li bohlokoa moralong oa boto ea potoloho ea LED. Ka kakaretso, liboto tsa potoloho tsa LED tse thehiloeng ka aluminium li fana ka phetisetso e phahameng ea mocheso le nako e telele, e leng se etsang hore e be tse loketseng bakeng sa tharollo ea mabone ea kajeno ea LED.
fihlela qeto e
Ka kakaretso, liboto tsa potoloho ea LED li bapala karolo ea bohlokoa ho ntšetseng pele theknoloji ea mabone a LED. Ho ba bonolo ha tsona, bokhoni ba tsona le ho tenyetseha ha tsona li etsa hore li be ntle bakeng sa mefuta e mengata ea lits'ebetso ho pholletsa le liindasteri tse fapaneng. Ha theknoloji e ntse e tsoela pele ho fetoha, liboto tsa potoloho ea LED li ka 'na tsa sebetsa hantle le ho feta le ho boloka litšenyehelo, e leng se tla etsa hore ho amoheloe litharollo tsa mabone a LED.
