A light-emitting diode (LED) inotungamira maviri-lead semiconductor mwenje sosi. Iyo pn-junction diode, iyo inoburitsa mwenje kana yaitwa.
Iwo anobatsira kwazvo kumabhenji ebasa, mapurojekiti ekuvaka mwenje, uye kunyangwe zvakananga pamidziyo yemagetsi nekuti vanoshandisa simba shoma uye vanoburitsa yakasimba uye yakagadzikana mwenje sosi.
Ndozvaunoda pakuvheneka purojekiti, mwenje usingabatike uye unogona kufambiswa nyore nyore, kubva kubhatiri kana chishandiso pachacho kunyange.
Kana magetsi akakodzera akaiswa kune anotungamira, maerekitironi anogona kubatanidzwa zvakare nemaburi eeelectron mukati memudziyo, achiburitsa simba muchimiro chephotons.
Mhedzisiro iyi inonzi electroluminescence, uye ruvara rwechiedza (rinoenderana nesimba reiyo photon) inotarwa neiyo simba bhendi gap reiyo semiconductor.
Iyo LED kazhinji idiki munzvimbo (isingasviki 1 mm2) uye yakasanganiswa yemaziso emukati inogona kushandiswa kuumba yayo mwaranzi maitiro.
Ichitaridza sezvinhu zvemagetsi zvinoshanda muna 1962, maLED ekutanga aiburitsa low-intensity infrared light.
MaInfrared LEDs achiri kushandiswa kazhinji sekufambisa zvinhu mumaseketi eremote-control, seaya ari muremote control kune akasiyana siyana emagetsi evatengi.
Iwo ekutanga anooneka-mwenje ma LED aivewo akaderera zvakanyanya, uye akaganhurirwa kune tsvuku. Ma LED emazuva ano anowanikwa pane inooneka, ultraviolet, uye infrared wavelengths, nekupenya kwakanyanya.
Ma LED ekutanga aiwanzo shandiswa semwenje mwenje wemidziyo yemagetsi, kutsiva madiki incandescent bulbs.
Nenguva isipi dzakaiswa mukuverenga nhamba muchimiro chezvikamu zvinomwe-zvikamu, uye dzaiwanzoonekwa mumawachi edhijitari.
Zvichangoburwa ma LEDs zvinovabvumidza kushandiswa muzvakatipoteredza uye mwenje webasa.
Ma LED ane akawanda mabhenefiti pane incandescent mwenje masosi anosanganisira kuderera kwesimba rekushandisa, hupenyu hurefu, kusimba kwemuviri, hukuru hudiki, uye nekukurumidza kushandura.
Mwenje-emitting diodes ave kushandiswa mumashandisirwo akasiyana semwenje wendege, marambi emota, kushambadzira, mwenje wakajairika, masaini emigwagwa, uye kupenya kwekamera.
Nekudaro, maLED ane simba rakakwana rekuvhenekesa mukamuri achiri kudhura, uye anoda kunyatsojeka ikozvino uye kupisa manejimendi pane compact fluorescent mwenje masosi ekuenzaniswa kwekubuda.
Ma LED akabvumira zvinyorwa zvitsva, mavhidhiyo ekuratidzira, uye masensa kuti agadziridzwe, nepo iwo masheji epamusoro anobatsirawo muhunyanzvi hwekufambiswa kwemashoko.
Ini ndini Joost Nusselder, muvambi weZvishandiso Chiremba, mushambadzi wemukati, uye baba. Ini ndinoda kuyedza michina mitsva, uye pamwe nechikwata changu ndanga ndichigadzira zvakadzama blog zvinyorwa kubva 2016 kubatsira vaverengi vakavimbika nematurusi & matipi ekugadzira.
