Tlhahlobo ea mokhoa o phahameng oa matla le mokhoa oa ho senya mocheso oa LED chip

Bakeng saLeseli la LED-emitting chips, ho sebelisa thekenoloji e tšoanang, matla a LED a le mong a phahame, a fokotsa matla a khanya, empa a ka fokotsa palo ea mabone a sebelisoang, e leng ho loketseng ho boloka litšenyehelo; Ha matla a LED e le 'ngoe a le manyenyane, a phahamisa katleho e khanyang. Leha ho le joalo, palo ea li-LED tse hlokehang ka lebone le leng le le leng lia eketseha, boholo ba 'mele oa lebone boa eketseha,' me bothata ba moralo oa lense ea optical bo eketseha, bo tla ba le phello e mpe holim'a lekhalo la kabo ea leseli. Ho ipapisitsoe le lintlha tse felletseng, hangata ho sebelisoa LED e nang le palo e le 'ngoe e sebetsang ea 350mA le matla a 1W.

Ka nako e ts'oanang, theknoloji ea ho paka le eona ke paramente ea bohlokoa e amang katleho ea leseli la li-chips tsa LED. Paramethara ea ho hanyetsa mocheso ea mohloli oa leseli la LED e bonahatsa ka ho toba boemo ba theknoloji ea ho paka. Theknoloji e ntlafetseng ea ho senya mocheso, e fokotsa ho hanyetsa mocheso, ho fokotsa khanya e nyenyane, ho khanya ho phahameng le ho phela nako e telele ea lebone.

Mabapi le katleho ea morao-rao ea theknoloji, haeba phallo e khanyang ea mohloli oa leseli la LED e batla ho finyella litlhoko tsa likete kapa esita le mashome a likete tsa lumens, chip e le 'ngoe ea LED e ke ke ea e finyella. E le ho finyella tlhokahalo ea khanya ea mabone, mohloli o khanyang oa lisebelisoa tse ngata tsa LED o kopantsoe ka lebone le le leng ho finyella mabone a phahameng a khanyang. Sepheo sa khanya e phahameng se ka finyelloa ka ho ntlafatsa katleho e khanyang ea LED, ho amohela liphutheloana tse khanyang tse khanyang le tse phahameng ka ho fetisisa ka li-multi-chips tse kholo.

Ho na le mekhoa e 'meli ea mantlha ea ho qhala mocheso bakeng sa li-chips tsa LED, e leng conduction ea mocheso le convection ea mocheso. Sebopeho sa ho qhala mocheso oaMabone a LEDe kenyelletsa sink ea mocheso oa motheo le radiator. The soaking plate ka hlokomela ultra-high heat flux heat transfer and solve the heat dissipation problem ofLED ea matla a phahameng. Letlapa le kolobisang ke sekoti se nang le micro-structure leboteng le ka hare. Ha mocheso o fetisoa ho tloha mohloling oa mocheso ho ea sebakeng sa mouoane, sebaka se sebetsang ka har'a cavity se tla hlahisa ketsahalo ea khase ea mokelikeli sebakeng se tlaase sa vacuum. Ka nako ena, mocheso o monya mocheso 'me molumo o atoloha ka potlako,' me karolo ea khase ea khase e tla tloha e tlatsa sekoti kaofela. Ha karolo ea khase ea khase e kopana le sebaka se batlang se bata, ho tla ba le condensation, ho lokolla mocheso o bokelitsoeng nakong ea mouoane, 'me mokelikeli o khutsitsoeng o tla khutlela mohloling oa mocheso oa mouoane ho tloha microstructure.

Mekhoa e sebelisoang hangata ea matla a phahameng ea li-chips tsa LED ke: katoloso ea chip, ntlafatso ea ts'ebetso e khanyang, ho paka ka bokhabane bo phahameng ba khanya, le hona joale e kholo. Le hoja palo ea luminescence ea hona joale e tla eketseha ka ho lekana, palo ea mocheso le eona e tla eketseha. Tšebeliso e phahameng ea mocheso oa mocheso oa ceramic kapa mohaho oa ho kenya resin ea tšepe o ka rarolla bothata ba ho senya mocheso le ho matlafatsa litšobotsi tsa pele tsa motlakase, optical le mocheso. E le ho ntlafatsa matla a mabone a LED, ho sebetsa ha lisebelisoa tsa LED ho ka eketseha. Tsela e tobileng ea ho eketsa ts'ebetso ea hona joale ke ho eketsa boholo ba lisebelisoa tsa LED. Leha ho le joalo, ka lebaka la ho eketseha ha hona joale ho sebetsa, ho senya mocheso ho fetohile bothata bo boholo. Ntlafatso ea mokhoa oa ho paka li-chips tsa LED e ka rarolla bothata ba ho felisa mocheso.
