Laambad diode The - mustaqbalka nalalka?

dioska- Light - a qalabka electroluminescent low-danab oo dhaadheer iftiinka marka electrons iyada oo pn-Isgoyska hoose marayay. warshadu hawada Light waxay dhacdaa marka muday iyada oo pn-isgoyska of sidayaal laga tirada badan yahay. dioska- The lagu eryi karaa DC, AC iyo danab garaaca wadnaha.

laambad diode waxaa ka mid ah anode iyo cathode ah. anode An for electrons soo jiitay, taas oo u qoondaysaa cathode ah, anode waxaa had iyo jeer codsatay danab wanaagsan. By codsanaya hadda koronto in ay xiriirada laambad u dhexeeya anode iyo cathode garoonka koronto, waxa ka caawisaa electrons ka cathode ku timaada (waxaa loogu yeeraa electrons free) xagga anode ka guuraan. Currently, iyo laambadahoodii yaryaraa LED - waa jihada ugu wanaagsan ee horumarinta ilaha nalal iyo iftiin. laambadihii Diode bedeli incandescent iyo halogeen, bilaabaan qaadashada tartanka xataa tamarta.

laambad diode waxay leedahay u gaar ah oo ay faa'iidada iyo khasaaraha. Its faa'iido weyn waa isticmaalka awoodda yar yahay. Waa min toban ah oo ku saabsan ka hooseeya in laambad incandescent ah, oo wuxuu ku saabsan yahay saddex jeer ka hooseeya in of nalalka ku. A isticmaalka korontada yar hadda, sababtoo ah laambad diode xoogga waa wax yar yahay.

Faa'iidada labaad waxaa loo arkaa inay muddo weyn - 100,000 saacadood, ama 11 sano hawlgalka joogto ah. Faa'iidada Next: iftiinka LED shiidaa aan dhib lahayn, waxay ka kooban tahay mercury lahayn iyo waa u fududahay in la tuuro ah. Sababo la xaqiiqada ah in geeddi-socodka ah ee laambadihii diode shiidaa kulayl ma uu helin, iyagu waa dab-ammaan ah, si ay loo isticmaali karaa in meelaha la hawo, tusaale ahaan saqafka ganaax. Faa'iidada ay hindiseen xooggoodu waa farsamo sare, ma ay joogaan xitaa ka cabsan ka dhaca height a, iyo waxa oo dhan si qalabka ka, taas oo ay ka samaysan yihiin mahad.

Yaraanshaha ee LED laambadihiinnuna badan mudnaan. Faa'iida ugu weyn waa qiimaha aad u sarreeya. Tusaale ahaan, iyo laambadahoodii yaryaraa diode qoyska of 9-10 W kor u kici doonto 2000 rubles, iyo nooca xafiiska (saqafka "Armstrong") - laga bilaabo 5000 rubles. daymada labaad ee soo saaraha 100 000 saacadood oo shaqo joogto ah ku dhaqanka tusi muddo badan ka yar ee hawlgalka. Tani waa sababta uu jiro crystal LED saamayn nabaad-a. saaraha waxay kaloo bixisaa damaanad ah oo ku saabsan waxyaabaha ay 3-5 sano. Marka la eego in laambad diode bixinaya laftiisa for in 5 sano, waxaad ku waayi kartaa lacag. khasaaro A dheeraad ah waa spectrum warshadu hawada iftiin cidhiidhi ah oo aan fiicneyn.

laambadihii LED ayaa la dalbadaa oo suuqa baabuurta. Tan iyo 1990, shirkadaha baabuurta bilaabay isticmaalaya Kokes ku headlamps baabuurta ee nalalka kala jejebiyey, tilmaamayaasha jihada, in size, in qol iftiinka iyo muraayada iwm Ilayska diode for gaari ay leeyihiin qaybaha kala duwan luminescence: .. From cas buluug. Haddaba, saarayaasha badan soo saaro baabuur for moodooyinka kala duwan ee uu Kokes oo tayo sare leh, taas oo ka furmay fursadaha weyn for mashiinada daafigaw.
