Iyo luminous nheyo yeiyo LED

ZveseChiedza chebasa rechirungu, Inotakurika Camping ChiedzauyeMultifuntional headlampShandisa iyo yakatungamirwa Bulb mhando. Kuti unzwisise iyo nheyo ye diode yakatungamirwa, kutanga kunzwisisa ruzivo rwepamhepo rwepamilonductors. Iyo yekugadzirisa zvinhu zveMiconondductor zvinhu zviri pakati pevatengesi uye kusimbisa. Zvimiro zvaro zvakasarudzika ndezvekuti: Kana Semiconductor inokurudzirwa neyekunze kwechiedza uye kupisa kwemamiriro, kugona kwayo kunoita kuchachinja zvakanyanya; Kuwedzera zvidiki zvidiki zvekusvibiswa kune yakachena semiconductor zvakanyanya kuwedzera kugona kwayo kuitisa magetsi. Silishon (si) neGermium (GE) ndiyo inonyanya kushandiswa semiconductive muzvemagetsi zvemazuva ano, uye magetsi azvo ekunze ane mana. Silishon kana maatomu echiGerman achiumba kristaro, maatomu akavakidzana anobata mumwe nemumwe, zvekuti emagetsi ekunze anofanirwa kugoverwa nematomu maviri, ayo anoumba chisungo chekristaro, chinogadzira chimiro chemanyorerwo chine hunyanzvi hwekumanikidza. Pamhepo tembiricha (300k), kufararira kwemhepo kuchaita kuti mamwe magetsi ekunze awane simba rakaringana kuti abvise chisungo chevhu uye ikaita ma elekitori emahara, maitiro aya anonzi intrinic kuenderana. Pashure pokunge magetsi asinga zivikanwe kuve yemagetsi emahara, basa rinosara muchisungo chinobatanidza. Uku kuzorora kunodaidzwa kuti gomba. Kuonekwa kwegomba chinhu chakakosha chinosiyanisa semiconductor kubva kuConstit.

Kana huwandu hushoma hwekusachena kwezvinhu zvakadai se phosphorus yakawedzerwa kune iyo Instrinsic Semiconductor, ichave neyakawedzera elekroni mushure mekugadzira chisungo chinobatanidza neimwe semiconductor maatomu emakesi. Iyi yakawedzera elektron chete inoda simba diki kwazvo kuti ubvise chisungo uye azova yemahara elektroni. Rudzi urwu rwekusachena semiconductor inonzi Electronic Semiconductor (N-TYPE SEMICODONONTURA). Nekudaro, kuwedzera huwandu hushoma hwelement almental Rudzi urwu rwekusachena semiconductor inonzi gomba semicononductor (P-mhando semicononductor). Kana n-mhando uye p-mhando semiconducuctors yakasanganiswa, pane mutsauko mukusangana kwemagetsi emagetsi emahara uye maburi pakubata kwavo. Electrons ese nemakomba akasiyana pakusangana kwepasi, kusiya basa rekupomera Iyi yepeperi yakabhadharwa manhamba anowanzodaidzwa kunzi nzvimbo yekubhadhara, uye ivo vanoomeswa padyo neyakajairwa n uye matunhu kuumba dunhu rakatetepa renzvimbo, rinozivikanwa sePN JN.

Kana chibviri Basas voltage inoiswa kumagumo ePN Junction Makomba achangobva kutsvaira anozodzorera nemagetsi emagetsi emahara, dzimwe nguva kusunungura simba rakawandisa muchimiro chemapikicha, icho chiri chiedza chatinoona chakabikwa neLDS. Spectrum akadaro yakamanikana, uye kubva pane chimwe nechimwe chinyorwa chine chakasiyana bhendi gakava, iyo wavelengths yemapikicha yakapihwa akasiyana, saka mavara emakororo anotarwa nezvinhu zvekutanga zvinoshandiswa.
