Mokhoa oa ho lokisa lebone la LED? Zhuhai o ruta bohle ho ithuta ho e etsa. Liphoso tse bonolo tsa LED le tsona li ka itokisa. Mabone a LED a fapane le mabone a pele a incandescent. Mabone a incandescent ha e le hantle a robehile. Ha e le hantle, li-tungsten filaments li chesoa. Mabone a LED a fapane. Mabone a LED a entsoe ka li-circuits tsa LED le lifaha tsa lebone tsa LED. Boholo ba mabone a LED a ka lokisoa, empa theko ea mabone a LED ha e phahame. Likarolo tse ngata, kahoo ha ho motho ea khethehileng ho lokisa mabone a LED, theko e phahameng, ba bang ha ba ikemisetse ho lokisoa, theko e tlaase, litšenyehelo tsa basebetsi li tlaase haholo, kahoo li ka lokisoa feela ke basebelisi. Mokhoa oa ho lokisa mabone a LED joalo ka basebelisi ba kakaretso? Ho na le mabaka a mangata a ho hlōleha ha mabone a LED, empa ho na le mefokolo e batlang e le bonolo. Ho khothaletsoa hore basebelisi ba ka leka ho itokisa le ho itloaetsa ho itloaetsa. Hangata mabone a LED a bona liphoso le mekhoa ea tlhokomelo 1. Lifaha tsa lebone la LED li senyehile. Ena ke ho hloleha ho tloaelehileng haholo. Ka kakaretso, ha lifaha tsa lebone la LED li chesoa, ho tla ba le matheba a matšo holim'a metsi. Ho ka khetholloa ho shebella ka hloko. Bakeng sa ho lokisa phoso ena, o hloka ho hlomella tšepe ea lesole. Empa ho thoe'ng haeba ho se na lebone la lebone la LED? E ka sebelisoa 150
ωHo hanyetsa ka ho le letšehali le ho nepahetseng ho nkela sebaka, haeba mokhanni oa kamehla oa hona joale a ka kopanngoa ka ho toba. 2. Sefa capacitance hloleha. Leseli le bonolo la LED ka kakaretso le lokisa motlakase oa AC ka mamello le ho theola khatello, ebe le matlafatsa mabone a lebone la LED ka ho sefa capacitor. Haeba ho hloleha ha filthara ea capacitor ho tla etsa hore motlakase o se tsitse, motlakase oa DC o tlase, o etsang hore leseli la LED le be lefifi. Lekanya bokhoni ba filthara ea filthara ka faele ea multimeter capacitor. Haeba phoso e le kholo, phoso e kholo ho feta hoo e ka bang 30%. Ho bolela hore bokhoni bo fokotsehile. Fumana matla a ho hanyetsa le matla a maholo ho feta a lekanang le parameter ea capacitor. 3. The capacity resistance drop -down module e senyehile. Mojule oa ho theoha ha bokhoni o na le capacitor capacitor le resistance parallel. E ka sebelisoa ho lekanya hore na bokhoni ba eona le ho hanyetsa li ka senyeha. 4. Kgutla. Hlakola lebone la LED 'me u hlahlobe hore na ho na le ho khaoha ha mohala o kenang kahare le ho tsoa. Haeba ho joalo, sebelisa tšepe ea solder ea motlakase ho e lokisa. 5. Phoso ea ho lokisa diode. Ho na le liphoso tse kang ho bula litsela le li-circuits tse khutšoane, tse ka bakoang ke ho phalla, kapa ho ka bakoa ke tšebeliso ea nako e telele ea ho hlōleha. Fumana diode ea rectifier e nang le boleng bo hananang le voltage e ka morao e fetang 350V le ea hajoale e sebetsang e fetang 0.5A, joalo ka 1N4004 1N4007, joalo-joalo. 6. Ho hloleha ha potoloho ea ho khanna ha LED kamehla. Bakeng sa litsebi tse hlokang phihlelo e amanang le elektronike ka mofuta ona oa ho hlōleha ho lokisa, ba ka fumana basebetsi ba litsebi tsa baetsi ba Zhuhai bakeng sa tlhokomelo. Moetsi o sebetsa ka ho khetheha ho hlahiseng lifaha tsa lebone la LED. E na le phihlelo e ngata. Ho molemo ho nkela lebone le lecha la lebone la LED sebaka ka mor'a ho hloleha ho bonolo ka holimo.
