Isibani se-diode - ikusasa lokukhanyisa?

Ama-diode alula amashini aphansi-voltage electroluminescent avela ekukhanyeni njengoba ama-electron adlula ekhoneni lokuqala le-pn. Ukukhanya kwe-light kwenzeka uma ukujova ngokusebenzisa i-pn-junction yabathwali abancane. Ama-diode angase ajabule ngombane oqhubekayo, oguquguqukayo nomfutho.

Isibani se-diode siqukethe i- anode ne-cathode. I-anode iklanyelwe ukuheha ama-electron akhiphe i-cathode, i-voltage enhle isetshenziswa njalo kwi-anode. Uma umshini kagesi usetshenziselwa oxhumana nabo bokukhanya, insimu kagesi ikhiwa phakathi kwe-anode ne-cathode, isiza ama-electrons avela ku-cathode (ama-elektrononi anjengobizwa mahhala) ukuya ku-anode. Okwamanje, izibani ze-LED - lesi yisiqondiso esithembisayo kakhulu sokuthuthukiswa kwemishini yokukhanyisa nemithombo elula. Izibani ze-diode zithatha izibani ze-incandescent ne-halogen, ziqala ukudala ukuncintisana ngisho nokulondoloza amandla.

Isibani se-diode sinenzuzo nezinsalela zayo. Inzuzo yayo eyinhloko amandla aphansi okusetshenziswa. Ilinganiselwa izikhathi eziyishumi ephansi kunalesi sibani se- incandescent, futhi cishe izikhathi ezintathu ezingaphansi kwesibani se-fluorescent. Ukusetshenziswa okuncane kwamanje kagesi kungenxa yokuthi amandla okukhanya kwe-diode aphansi kakhulu.

Inzuzo yesibili yinto yokuphila ende yamahora angu-100 000, noma iminyaka engu-11 yokuqhutshwa okuqhubekayo. Inzuzo elandelayo: isibani se-diode cishe asilimazi, asiqukethe i-mercury futhi kulula ukuyilahleka. Ngenxa yokuthi ngesikhathi sokusebenza, izibani ze-diode cishe azifudumali, zibhekwa njengokungabi namlilo, ngakho-ke zingasetshenziswa ezindaweni ezinomoya ophuthumayo, njengesibonelo, esimweni sokumiswa okwesikhashana. Inzuzo yamadivaysi yizikhwepha zabo eziphezulu, azikho ngisho nokwesaba ukuwa kusukela ekuphakameni, futhi lokhu konke kungenxa yezinto ezenziwe kuzo.

Ukungahleleki kwezibani ze-LED kungaphezu kwezinzuzo. Ukungalungi okuyinhloko kuyinani eliphezulu kakhulu. Isibonelo, izibani ze-diode zasendlini enegunya lika-9-10 W zizobiza izindlu ezinama-ruble angu-2000, kanye nohlobo lwehhovisi (i-Armstrong eveyili) - kusuka kuma-ruble angu-5000. Okwesibini okungalungile: amahora angu-100 000 okuqhubekayo okushiwo ngabakhiqizi ekusebenzeni kubonisa impilo emfushane kakhulu yensizakalo. Lokhu kubangelwa ukuthi kukhona umphumela wokuchithwa kwamakristalu e-LED. Kodwa umkhiqizi unikeza isiqinisekiso semikhiqizo yayo eminyakeni engu-3-5. Njengoba unikezwe ukuthi isibani sesidingo sikhokhela ngeminyaka emihlanu, ungalahlekelwa yimali yakho. I-drawback elandelayo yukukhanya okuncane kwe-beam nokukhanya okungajabulisi kwe-luminescence.

Izibani ze-LED zithole isicelo sabo embonini yezimoto. Kusukela ngawo-1990, abakwa-automakers baqale ukusebenzisa ama-LED emakhanyeni omoto, izibani zokuyeka, izinkomba zokuqondisa, ubukhulu, ukukhanyisa kwangaphakathi nezinsimbi zethuluzi, njll. Izibani ze-diode zezimoto zinezinto ezihlukahlukene zokukhanya: kusuka ebomvu kuya eluhlaza okwesibhakabhaka. Manje abakhiqizi abaningi bakhiqiza i-LED ephezulu yezimoto zamamodeli ahlukene, lokhu kuvulwa amathuba amakhulu okulungisa imoto.
