In meel ka mid ah "nal Ilyich" oo ay iftiinka ugu yimid keentay

Isha ugu iftiinka maalmahan, waxaan shaki ku jirin, noqon laambadihii LED. Waa a-teknoolojiyad sare saarka casriga ah, iftiinka LED si tartiib tartiib ah u yimaado si uu u bedelo nalka dhaqanka incandescent, iyo sidoo kale noocyo kala duwan oo qalab tamarta lagu badbaadinayo, taas oo suuqa gudaha kulan nalalka sidoo kale ahaayeen xad dhawaan.

A yar oo taariikh

warshadu hawada Light inta lagu guda jiro marinka ee hadda korontada iyada oo isgoyska pn a qalab Semiconductor ah ayaa loo yaqaan tan iyo bilowgii XX qarnigii. Sayidka, Henry Joseph kulminna, hindisa ee UK ee 1907, waxaa lagu tilmaamay saameyn electroluminescence maraya koronto iyada oo labo ka mid ah biraha - Karbid Kremniya, Ulasocto siyasad huruud ah, cagaaran iyo orange at cathode ah. tijaabo la mid ah ayaa fuliyay 1923 by cilmiga Soofiyeeti Olegom Losevym (jidka ag fadhida, tan iyo 70s hore 'by saynisyahano American LED ilayska si fiican loo magacaabay - «Losev Light», ka dib magacaaga la illoobay). Laakiin dhab ahaantii haddii aan helay this waxaa la siiyaa, oo sidaas daraaddeed ma baarayaa dhowr sano ee.

In 1961, waxaa la xiranayo been abuurtay waa infrared ah, iyo in 1962 - shaqeeyay kala duwan ee LED iftiinka (cas). Ka dibna, waxaa been abuurtay si joogto ah hagaagtay. Siday u kala horreeyaan, hoos iyo kharashka. Sidaas daraaddeed, 1968 on the nalalka LED, qiimaha ahaa oo ku saabsan $ 200, laakiin sababta oo ah isticmaalka wax ku ool ahaa mid aad u kooban.

Maanta, iyo laambadahoodii yaryaraa, kuwaas waxaa loo isticmaalaa ku dhowaad meel kasta. Si arrintan loo sameeyo, Kokes waxaa laga heli karaa dhammaan noocyada caanka ah ee u saftay: E27, E14, GU5.3, G53, GU10, G13.

Iftiinka LED ka khayr badan caadiga ah?

nalalka LED bixiyaan faa'iidooyinka soo socda:

• oolnimada sare u Yeelaa Eebe. tusaalooyin Modern kulan nalalka, kuwaas oo ku dhimaya this waa u dhigma halide biraha iyo sodium laambadihii dheecaan.
• isticmaalka awoodda Low. Waxaa dhowr jeer ka hooseeya ilo iftiin caadiga ah.
• Nolosha adeeg dheer. Iyada oo ku xidhan LED saaraha iyo technology laambadda socon karaa soddon mid ka mid boqol oo kun oo saacadood. Tirada wareegyada on-off, ma saameyn badan on nolosha Kokes.
• xoog High iyo gariirka. Taana waxaa lagu gaarayaa ay sabab u tahay xaqiiqada ah in aysan jirin xasaasi u ah qaybaha stress makaanikada.
• tiiro hoose. Si ka duwan laambadihii kale, LED dhow isla markiiba wuxuu bilaabaa inuu iftiimiyo at dhalaalka buuxa. Ka sokow, iyadu ma cabsato mawjadahaa awood.
• saaxiibnimo High deegaanka. Si ka duwan ugu nalalka tamarta lagu badbaadinayo, Kokes aan ku jira mercury ama waxyaabaha kale ee waxyeelada leh.

Waa wax aan macquul in aan ku xuso xaqiiqada ah in darawallada iyo aad u badan ay bilaabeen in ay codsan sanad kasta LED siraaddo gaariga. Lahaanshaha tayada la mid ah sida uu Kokes ee nalalka qoyska, waxay soo saartay la embodiments kala duwan ee u saftay (H1, H3, H7, H8, H10, iwm). Waxay rakiban yihiin in laydhkaaga gaari madaxa, iyo ma aha oo kaliya sida ceeryaanta, laakiin sidoo kale sida hooseeyo oo dogob sare.

Waxaa laga yaabaa in khasaare oo kaliya, taas oo uu leeyahay a nal LED - qiimaha sare. LED jaban (LL) kharash ah oo ku saabsan 500 rubles, iyo qiimaha ugu qaalisan (SPOT) gaari karaan 5000. Inkastoo oo dhan, sida ay iyagu yidhaahdaan, waa qaraabo. nolosha adeeg badan ee laambadihii LED, by tirada korontada baabbi'iyey bateen si fiican laga yaabaa in ka sii faa'iido badan isticmaalka nalalka caadiga ah.
