Ka kholo e potlakileng ea mabone a LED ho elektronike ea likoloi, mathata a macha a LED a hlahile.Sengoliloeng sena se hlalosa litšitiso tsa mantlha tseo baetsi ba matla a mabone ba tobaneng le tsona le ho hlahloba hore na li ka rarolloa joang ka module e ncha ea MPS ea koloi ea MPS - MPM6010-AEC1 3.
Melemo ea bophelo bo bolelele, boholo bo bonyenyane, le tšebeliso e tlase ea matla a li-LED li lumellana hantle le litlhoko tsa likoloi tsa kajeno tse baballang tikoloho 'me li tlatselitse ho tuma ha li-LED tsa mabone a likoloi.Ho tloha ho mabone a potolohileng, matšoao a matšoao, le khanya ea skrine ea digital ka hare ho koloi ho fetola matšoao, mabone a marang-rang, mabone a fog, le mabone a motšehare ka ntle ho koloi, li-LED li se li sebelisoa hohle ka hare le ka ntle.Haufinyane, li-LED li lebelletsoe ho nkela sebaka sa halogen kapa xenon-based high-powered lightlights.
Baenjineri ba kajeno ba mabone a likoloi ba tobane le liphephetso tse 'maloa tsa tekheniki ho rala li-LED hore li be nyane hape li ikhethile, ha ka nako e ts'oanang li ntlafatsa ts'epahalo, ho itšireletsa khahlanong le tšitiso ea motlakase, le ho ntlafatsa ts'ebetso ea mocheso.
Ho tšepahala ho phahameng ho bohlokoa ho boenjiniere ba likoloi, 'me sena ke sa bohlokoa ka ho khetheha maboneng a koloi a ka ntle, moo boemo ba koloi (ho reteleha, ho emisa, li-alarm, joalo-joalo) bo itšetlehileng ka eona.Molao-motheo o akaretsang oa ho eketsa ho tšepahala ke ho fokotsa palo ea likarolo tse ka har'a boto: likarolo tse fokolang, lintlha tse fokolang tse ka 'nang tsa hlōleha, le lisebelisoa tse fokolang tse hlokahalang.Ha moralo o le bonolo, ho bonolo ho o laela le ho o tlisa 'marakeng.
Ntle le moo, ha litsamaiso tsa LED li ntse li fokotseha, lisebelisoa tsa elektroniki tse amanang le tsona le tsona li tlameha ho fokotseha.Tsela e 'ngoe e tloaelehileng ea ho finyella meralo e menyenyane ea boto ke ho eketsa lebelo la ho fetola mokhanni, kahoo ho fokotsa boholo ba li-inductors le li-capacitor tse amanang.Leha ho le joalo, maqhubu a phahameng a ho fetoha a baka keketseho e matla ea tšitiso ea motlakase;kamano e sekoere lipakeng tsa tšitiso ea makenete ea motlakase le maqhubu a switjha e bolela hore ho imena habeli ha maqhubu a switjha ho eketsa tšitiso ea motlakase ka makhetlo a mane.Ho rarolla bothata bona, baqapi ba tlameha ho ntlafatsa sebopeho sa potoloho mme ba khethe likarolo tsa tahlehelo e tlase ha ba ntse ba fokotsa li-loops tse hlokolosi moo maqhubu a nakoana a sebetsang;Litsela tsena tse hlokolosi hangata li na le li-switches, li-inductors tsa polokelo ea matla, le li-decoupling capacitor.Tsela e 'ngoe ea ho fokotsa EMI ke ho eketsa tšireletso ea tšepe, eo ka sebele e tlang le keketseho e kholo ea litšenyehelo, e sa amoheleheng bakeng sa' maraka oa mabone o sa tsotelleng theko.
Ho feta moo, le hoja li-LED li se na matla a fokolang ho feta mabone a halogen kapa a incandescent, tsamaiso ea mocheso e ntse e le taba e kholo kaha e amana ka ho toba le nako ea bophelo ea LED.Li-LED li tsejoa ka lihora tse makholo a likete tsa ho sebetsa, empa mocheso o phahameng oa mateano a ka etsa hore bophelo ba tsona bo theohe, 'me maemo a leholimo a thata ao likoloi li ka sebetsang ho tsona li ka fokotsa bophelo ba LED.
