Molao-motheo o Khanyang oa Lifaha tsa Lebone la LED tse mebala e 'meli

The light -emitting diode is usually referred to as LED lamp beads, which are made of compounds such as 镓 (GA), arsenic (AS), phosphorus (P), nitrogen (n). Ha electron le cavity li kopantsoe, li ka khantša leseli le bonahalang, kahoo li ka sebelisoa ho etsa diode e khanyang. Lifaha tsa lebone tsa LED li atisa ho sebelisoa lipotolohong le lisebelisoa e le mabone a bontšang, kapa sebopeho kapa pontšo ea digital. 'Mala o khanyang le bokhoni bo khanyang ba diode e khanyang ea LED e amana le lisebelisoa le mekhoa ea ho etsa li-LED. Hajoale, lifaha tsa lebone la LED tse nang le mebala e meraro ea khanya e khubelu, e tala, le boputsoa li sebelisoa haholo. Leqhubu la maqhubu a mebala e fapaneng le lona le fapane. Ka kakaretso, ho fokotseha ha khatello ea PN ho ka ikemisetsoa ho tseba 'mala oa wavelength oa diode tse khanyang. 1. Sebopeho sa encapsulation ea mebala e 'meli ea khanya ea LED -emitting diode ke efe? Lebaka leo ka lona mefuta e 'meli ea LED light -emitting diode e ka hlahisang mebala e' meli ea khanya ke haholo-holo ho paka mebala e 'meli e fapaneng ea li-chips ka har'a bracket e le' ngoe. Ka mantsoe a bonolo feela, sebopeho sa eona se haufi le "tube" ea "monochrome emitting diode" e tloaelehileng, ebe o kenya motsoako o mong oa 'mala. The two-color LED e ka aroloa ka maoto a mabeli ntle le polar two -color LED mabone lifaha, le two -legged co -yin -yang two -color LED mabone lifaha. Ea bobeli, molao-motheo o khanyang oa diode e khanyang ea tšusumetso ea tšusumetso ea mefuta e 'meli e sa fetoheng ea mebala ea LED e khanyang ke lipini tse peli. Mohlala, ho na le lithakhisa tse peli ho li-diode tse khanyang tsa LED tse khubelu le tse tala tse se nang polarized. Ho tjheseletsa ho fetelletseng le ho kgutshwane ka maoto, n pole le maoto a malelele. Ha motlakase o phalla ho tloha maotong a malelele ho ea maotong a makhutšoane, lifaha tsa lebone tsa LED tse khubelu le tse tala tse mebala e habeli li sebetsa ka mokhoa o tloaelehileng, 'me leseli le letala ha le sebetse hobane hona joale ho phalla ho tloha leotong le lekhutšoanyane ho ea leoto le lelelele, sefaha se khanyang se setala sa mabone a LED a se nang polar a khubelu le a botala a mabeli a mebala-bala a tloaelehile, leseli le letala le tloaelehile Mosebetsi, mabone a khubelu ha a sebetse, e le ho finyella morero oa ho laola phallo ea hona joale ea mebala e 'meli e khubelu le e tala. Three, three -legged co -yin -co -aode two -color LED lifaha tsa lebone tsa leseli, tse tharo -legged two -color LED light -emitting diode, mebala e 'meli e fapaneng ea li-tube cores e arolelana pole e le' ngoe. Lithako tse tharo li fapane, 'me leoto le lelelele ka ho fetisisa la sechaba bohareng ke qetello ea sechaba. Lifaha tsa lebone tsa LED tse tharo-maoto le tse peli li ka aroloa ka mefuta e 'meli: cathode e tloaelehileng le LED e tloaelehileng ea anode ho latela polarity e fapaneng ea lipini tsa ho qetela tsa sechaba. Kahoo. U ka khetholla joang pakeng tsa polarity ea maoto a mararo a mabeli a mebala ea LED e khanyang? Phapang lipakeng tsa Yin ea Bokomonisi le yang haholo-holo ke ho bona lipalo tse ntle le tse mpe tsa pina e telele ka ho fetisisa ea sechaba. Haeba pini ea sechaba e le mpe, ke "Gongchen pole LED LED light -emitting diode". LED ea hona joale ka kakaretso e phalla ho tloha ho electrode e ntle, 'me eleketrode e mpe e tsoa.
