Esikhundleni "isibani Ilyich" weza LED

Umthombo ethembisayo yokukhanya kulezi zinsuku, akungabazeki, babe izibani LED. Ingabe zobuchwepheshe umkhiqizo yesimanje, ukukhanya LED kancane kancane kuza esikhundleni bendabuko esikhipha isibani, kanye izinhlobo ezahlukene kumadivayisi energy esisindisa, okuyinto emakethe yasekhaya yokukhanyisa zalapho kade futhi esanda kutholakala.

Umlando omncane

ekushayweni ngesikhathi ukudlula kagesi ngokusebenzisa okuhlangana PN Khanyisa sedivayisi Semiconductor yaziwa kusukela ekuqaleni XX leminyaka. Ngakho, uHenry Joseph uphetha, umsunguli we-UK ngo-1907, kwachazwa electroluminescence umphumela bedlula i kagesi ngokusebenzisa pair of metal - Karbid Kremniya, ephelezelwa kukhanya ophuzi, oluhlaza okotshani futhi orange ngesikhathi cathode. Ekuhloleni okufanayo Kwakuseshwa 1923 by usosayensi Soviet Olegom Losevym (endleleni, kwaze kwaba sekuqaleni kwawo-'70 ososayensi American LED isibani ubizwa kufanele ngokuthi - «Losev Khanyisa», kamuva igama kwaba ukhohliwe). Kodwa ngempela lutho uma lokhu okutholakele alinikwa, futhi ngenxa yalokho akubona uphenyo amashumi eminyaka.

Ngo-1961, kwathiwa lobunikazi okusunguliwe infrared, futhi ngo-1962 - wasebenza ekukhanyeni (obomvu) ububanzi LED. Ngemva kwalokho, lo mshini ngokuqhubekayo ngcono. Ngokulandelana, kwehle futhi izindleko zawo. Ngakho, ngo-1968 ku-ama LED, inani lase cishe u- $ 200, kodwa ngenxa ukusetshenziswa kwabo okuwusizo wawumncane kakhulu.

Namuhla, lezi izibani zisetshenziswa cishe yonke indawo. Ukuze wenze lokhu, LED ayatholakala nge zonke izinhlobo ezidumile ofeleba: E27, E14, GU5.3, G53, GU10, g13.

I LED ukukhanya kangcono kunokuvamile?

Izibani LED ukunikeza izinzuzo ezilandelayo:

• High kahle elikhanyayo. izibonelo Modern yalezi zalapho ukukhanyisa kule ipharamitha kukhona ufana halide metal kanye sodium nezibani khulula.
• Low power ukusetshenziswa. Kuyinto izikhathi eziningana ngaphansana ukukhanya imithombo ezivamile.
• ukuphila isikhathi eside. Kuye nomkhiqizi futhi isibani ubuchwepheshe LED ingahlala kusukela kwabaneminyaka engamashumi amathathu kuya ayizinkulungwane eziyikhulu amahora. Isibalo ku-off imijikelezo, hhayi umthelela kakhulu empilweni LED.
• Izikhwepha High vibration. Lokhu kufezwa ngenxa yokuthi ayikho nozwelo mechanical izingxenye ukucindezeleka.
• I inertia ongaphakeme. Ngokungafani nezinye izibani, LED cishe ngokushesha uqala kukhanye at ukugqama egcwele. Ngaphandle kwalokho, yena akesabi amandla yokwanda kwama.
• nobungane High kwemvelo. Ngokungafani izibani energy-saving, LED baye ukuqukatha mercury noma ezinye izinto ezilimazayo.

Akunakwenzeka ingasaphathwa yokuthi abashayeli abaningi baqala ukusebenzisa njalo ngonyaka LED izibani ukuze imoto. Ukuba zimfanelo njengoba LED abendlu ukukhanyisa, basuke wakhipha ne embodiments ezihlukahlukene caps (h1, h3, H7, H8, h10, njll). Basuke efakwe ekhanda imoto izibani, hhayi kuphela njengoba inkungu, kodwa futhi njengoba ongaphakeme futhi uvumelanise okusezingeni eliphezulu.

Mhlawumbe ethile kuphela, okuyinto has a LED isibani - zibiza. LED Eshibhe (LL) kubiza ruble mayelana 500, futhi izindleko eqolo (Spot) ongafinyelela 5000. Nakuba zonke, njengoba besho, lilinganiselwe. inkonzo nokuphila enkulu izibani LED, siphindwe ngesibalo kagesi kudliwe kube kuhle ngisho inzuzo engaphezu kuka-ukusetshenziswa ezivamile ukukhanya ama.
