The diode nyale - tsogolo la kuunikira?

Kuwala diodes - wozama voteji electroluminescent zipangizo zomwe zimatulutsa kuwala pamene ma elekitironi kudutsa pulayimale pn-zolumikizanazo. Kuwala umuna kumachitika pamene jekeseni kudzera pn-pamphambano ya onyamula ochepa. The diodes akhoza lotengeka DC, AC ndi zimachitika voteji.

Nyali diode zikuphatikizapo ndi anode ndi cathode. An anode kukopa ma elekitironi, amene allocates ndi cathode, ndi anode nthawi zonse ntchito voteji positive. Mwa kugwiritsa ntchito panopa magetsi kuti ojambula nyali pakati pa anode ndi cathode minda ya magetsi, izo kumathandiza ma elekitironi panamveka ku cathode ndi (zimenezi zimatchedwa ufulu ma elekitironi) kusuntha kwa anode lapansi. Panopa LED nyali - ndi kwambiri zingamuthandize malangizo a chitukuko cha kuyatsa ndi kuwala kochokera. Diode nyali m'malo incandescent ndi halogen, kuyamba kupanga mpikisano ngakhale magetsi.

Nyali diode ali yake ubwino ndi kuipa. mwayi waukulu ndi otsika mowa mphamvu. Ndi khumi nthawi poyerekeza wa nyali incandescent, ndipo watsala katatu poyerekeza wa fulorosenti lapansi. A yaing'ono magetsi mowa panopa chifukwa nyali mphamvu diode ndi otsika kwambiri.

The mwayi wachiwiri imatengedwa kuti ndi nthawi yaikulu - maola 100,000, kapena zaka 11 opareshoni mosalekeza. Kenako mwayi: LED kuwala pafupifupi vuto lililonse, liribe Mercury ndi yosavuta kutaya. Chifukwa chakuti mu ndondomeko ya diode nyali pafupifupi magetsi, iwo ndi moto abwino, iwo akhoza kugwiritsidwa ntchito mu malo ndi mpweya osauka, mwachitsanzo mu kudenga inaimitsidwa. Ubwino wa zipangizo ndi mkulu mawotchi mphamvu zawo, iwo siali choncho ngakhale mugwa kuchokera kumwamba, ndipo ndi mathokozo onse ndi zida kumene amapangidwira.

Kuperewera mu anatsogolera nyali kuposa phindu. The sangathe ndicho mtengo wapatali kwambiri. Mwachitsanzo, banja diode nyali ya 9-10 W ndalama mpaka 2000 rubles, ndi ofesi mtundu (denga "Armstrong") - kuchokera rubles 5000. Molakwika wachiwiri kwa Mlengi 100 000 maola ntchito yothandizira kuchita kusonyeza laling'ono kwambiri nthawi ya opaleshoni. Ichi ndi chifukwa pali galasi LED kudzitsitsa kwenikweni. Mlengi komanso imapereka chitsimikizo pa malonda awo zaka 3-5. Popeza kuti diode nyale malipira yokha mu zaka 5, mukhoza kutaya ndalama zanu. A sangathe zina ndi yopapatiza kuwala umuna sipekitiramu ndi zosasangalatsa.

nyali LED akhala ntchito ndi makampani magalimoto. Popeza mma 1990, galimoto opanga anayamba ntchito LEDs mu headlamps magalimoto mu nyali nanyema, malangizo zizindikiro, kukula, mu chipinda kuwala ndi lakutsogolo etc. The diode nyale galimoto ali osiyana luminescence sipekitiramu: .. Kuyambira wofiira buluu. Tsopano, opanga ambiri kubala magalimoto chifukwa zitsanzo zosiyanasiyana LEDs mkulu khalidwe, zimatipatsa mwayi wautali kwambiri kwa makina ikukonzekera.
