A tarihin na yin amfani da semiconductors mazan fara amfani E-type fitilu. AS Popov, wanda yana dauke da kirkiro na rediyo, neman ta hanyar sauki semiconductor na'urar, gaban igiyoyin rediyo. Popov farko diode (injimin gano illa) an kafa daga semiconductor guntu gyarawa a wani mariƙin, da kuma bazara lamba na wani nuna tungsten, ko karfe. Wannan lamba da aka dogara a kan semiconductor yankin, da kuma dangane da lamba nufi da za a samu mafi bayyananne siginar transceiver.

Mene ne wani LED, hanyar shi ya dubi a kan ginshiƙi?

LED iri-iri kira semiconductor kashi ciwon singularity na crystal zuwa emit haske a ƙarƙashin rinjayar da lantarki wucewa therethrough. Wannan sakamako ne ba a duk semiconductors, amma waɗanda a wadda a aiwatar da recombination na electrons da ramuka a saki makamashi na faruwa a cikin Tantancewar kewayo. LED a matsayin al'ada diode, a pn-maha? Ar da ya wuce yanzu, a daya shugabanci kawai.

A fasalin da LEDs matsayin haske emitting na'urar shi ne cewa an saki kai tsaye haske kamfani mai suna Quanta. Wannan ya bambanta da shi daga Lagwani fitilu, wanda ya auku farko dumama karkace zuwa wasu zazzabi, ko halogen fitilu tare da wani ionization sakamako.

LED - polarity nadi

LED nadi a kan ginshiƙi sa shi sauki domin sanin polarity, amma domin sanin shi daga sabon sayi abu, kana bukatar ka dubi lamba. M anode m kullum yana da mafi tsawon fiye da cathode.

Idan LED da aka saka a kan jirgin, kuma ta, ga abin da dalilai, yana da wani alama abubuwa, da polarity na semiconductor za a iya ƙaddara, mukalli jikinsa. Daga gefe na cathode (korau m) a jiki da wani lebur siffar daraja. Har ila yau, da m yadi irin jagoranci gani ta ciki. Kama daga cikin kofin, cikinsa da semiconductor guntu aka located, yana da wani kai tsaye dangane da cathode.

A cikin akwati inda ba shi yiwuwa domin sanin polarity na sama hanyoyin, amma akwai gaban wani lantarki multimeter, za ka iya amfani da shi. Dauki al'ada diode na san polarity ba a ci gaba da aiki na'urar da haɗi zuwa semiconductor. Adanar da polarity lokacin da diode gudanar halin yanzu. LED da alaka da ma'auni schupam. Tabbatar da cewa shi gudanar halin yanzu, lura polarity.

A LED a kan jirgin
