Selelekela

Mabone a khabiso a LED a tumme haholo lilemong tsa morao tjena, a tlisa sebaka se makatsang le se setle libakeng tse fapaneng. Ho tloha lipontšong tsa matsatsi a phomolo ho ea ho meralo ea sejoale-joale ea kahare, mabone ana a fetotse mohopolo oa mabone a khabisitsoeng. Empa ke eng e etsang hore mabone a khabiso a LED a be a ikhethang hakaale? Sehloohong sena, re kenella ka har'a mahlale a khanya ka mor'a limakatso tsena tse khantšang, re manolla theknoloji le melao-motheo e etsang hore li khanye. Eba le rona ha re ntse re hlahloba lefatše le khahlang la mabone a khabiso a LED le ho utloisisa ka ho teba khanya ea ona e hapang maikutlo.

Mabone a Khabiso a LED ke afe?

Mabone a khabisitsoeng a LED, kapa mabone a khabisitsoeng a Light Emitting Diode, ke mofuta oa lisebelisoa tsa mabone tse sebelisang boits'oaro ba lielektrone ho hlahisa leseli le bonahalang. Ho fapana le mabone a tloaelehileng a incandescent kapa fluorescent, a itšetlehileng ka mocheso le khase e tsoang ka ho latellana, mabone a LED a sebetsa ho latela melao-motheo ea mabone a boemo bo tiileng. Ka ho romela hona joale ka thepa ea semiconductor, mabone a LED a hlahisa khanya ka katleho, a fana ka nako e telele ea bophelo le matla a ikhethang a matla.

Fisiks e ka morao ho mabone a LED

Mabone a LED a sebetsa ka molao-motheo oa electroluminescence, mokhoa oa ho hlahisa leseli ka ho fetisa motlakase ka thepa. Ka har'a lebone la khabiso la LED, ho sebelisoa thepa ea semiconductor, eo hangata e entsoeng ka motsoako oa lintho tse kang gallium, arsenic le phosphorous. Ha motlakase o sebelisoa ho semiconductor, o hlasimolla lielektrone tse ka har'a lintho tse bonahalang, e leng se etsang hore li qhomele maemong a phahameng a matla. Ha lielektrone li khutlela libakeng tsa tsona tsa pele, li ntša matla ka sebōpeho sa photon, tse hlahisang khanya e bonahalang.

Color Spectrum le Lebone la LED

E 'ngoe ea litšobotsi tse khahlang ka ho fetesisa tsa mabone a khabiso a LED ke bokhoni ba bona ba ho hlahisa leseli ka mebala e fapaneng. Ka ho fetola sebopeho sa lisebelisoa tsa semiconductor, mabone a LED a ka etsoa hore a ntše maqhubu a itseng a khanya. Mabone a mebala a mabone a LED a ipapisitse le lekhalo la sehlopha sa matla sa semiconductor, ho khetholla matla a li-photon tse hlahisitsoeng. Mohlala, LED e khubelu e na le lekhalo le leholoanyane la sehlopha sa matla, athe LED e putsoa e na le lekhalo le lenyane la sehlopha sa matla. Ka ho kopanya mebala ena, mabone a LED a ka etsa mefuta e mengata ea mebala, e fana ka menyetla e sa feleng ea lisebelisoa tsa mabone a khabisitsoeng.

Melemo ea Leseli la Khabiso ea LED

Mabone a khabiso a LED a fana ka melemo e mengata ho feta likhetho tsa mabone a setso, a etsa hore li tuma le ho feta malapeng, likhoebong le libakeng tsa sechaba. Taba ea pele, mabone a LED a sebetsa hantle haholo, a sebelisa matla a fokolang haholo ho feta mabone a incandescent kapa a fluorescent. Ts'ebetso ena ha e thuse feela ho fokotsa tšebeliso ea matla empa hape e fetolela ho boloka litšenyehelo ka nako e telele.

Taba ea bobeli, mabone a LED a phela nako e telele haholo ha a bapisoa le mabone a setso. Li ka tšoarella nako e telele ho fihlela makhetlo a 25, ho fokotsa bothata ba ho nkela sebaka khafetsa. Ho feta moo, mabone a LED a tšoarella ka nako e telele 'me ha a na tšusumetso, e leng se etsang hore e be khetho e nepahetseng bakeng sa mekhabiso ea kantle kapa libaka tse tloaetseng ho thothomela.

Ho feta moo, mabone a khabisitsoeng a LED a na le tikoloho, kaha ha a na lintho tse kotsi tse kang mercury, tse atisang ho fumanoa ka mabone a fluorescent. Sena se etsa hore mabone a LED a be bonolo ho lahla le ho fokotsa tšusumetso ea tikoloho e amanang le likhetho tsa mabone a setso.

Lisebelisoa tsa Leseli tsa Khabiso tsa LED

Mabone a khabiso a LED a fana ka mefuta-futa ea likopo tsa bona, a eketsa botle le boselamose ho litlhophiso tse fapaneng. Li sebelisoa haholo linakong tsa mekete, li ntlafatsa botle ba lifate tsa Keresemese, li khantša lipontšo tsa ka ntle, le ho etsa hore ho be le moea oa boselamose. Ho feta moo, mabone a LED a kenyelelitsoe haholo meahong ea mabone a meralo, a totobatsa likarolo tse ntle tsa meaho, marokho le matšoao.

Lilemong tsa morao tjena, mabone a marang-rang a LED a fumane botumo bakeng sa ho fetoha ha bona le bokhoni ba ho fetola libaka. Li-LED tsena tse tšesaane, tse tšehelitsoeng ka sekhomaretsi li ka kenngoa habonolo ka tlas'a likhabinete, haufi le siling, kapa litepising, tse fanang ka mabone a poteletseng le a tebileng. Mabone a lithapo tsa LED a boetse a sebelisoa haholo bakeng sa lintlha-khōlō, litsela tse hlalosang, le ho etsa libopeho tse khabisitsoeng ka bobeli ka hare le ka ntle.

Qetello

Ho tloha ho khanya ea bona e makatsang ho isa ho matla a bona a matla a ikhethang, mabone a khabiso a LED a fetotse lefatše la mabone. Ho utloisisa saense ka mor'a limakatso tsena tse khanyang ho re lumella ho ananela melemo ea bona le ho hlahloba menyetla ea bona e se nang moeli. Ha theknoloji e ntse e tsoela pele, mabone a khabiso a LED a tla tsoela pele ho fetoha, a fana ka likhetho tse ncha le tse hohelang bakeng sa ho theha tikoloho e makatsang. Kahoo, nakong e tlang ha u bona khanya e tsotehang ea mabone a khabiso a LED, hopola saense e tsotehang e etsang hore ba phele. Khantša sebaka sa hau 'me u amohele limakatso tsa mabone a LED!
