Kodi Pali Kusiyana Kotani Pakati pa Guangmin Diode ndi Zowunikira Zachikhalidwe?

Poyerekeza ndi nyali yachikhalidwe ya incandescent, pali maubwino angapo a kuwala -sensitive diode. Choyamba, palibe filament ya diode ya Guangmin, yomwe imachotsa kuthekera koyaka, kotero moyo wautumiki ndi wautali. Kuonjezera apo, mababu apulasitiki ang'onoang'ono a diode ya Guangmin amapangitsa kuti kuwala kwa magetsi kukhale kolimba. Dera lamakono lamagetsi ndilosavuta kugwiritsa ntchito. Njira yowala ya nyali zamtundu wa incandescent imakhala ndi kutentha kwakukulu, komwe kumawononga mphamvu. Ngati simugwiritsa ntchito kuwala ngati chipangizo chotenthetsera, ndiye kuti mphamvu zambiri zamakono sizidzatulutsa mwachindunji kuwala kowonekera. Ma calories opangidwa ndi Guangmin diode ndi ochepa kwambiri. Kunena zoona, mphamvu zamagetsi zochulukirapo zimayaka mwachindunji kuti zichepetse kufunika kwa mphamvu zamagetsi kwambiri. Pakadali pano, chifukwa chogwiritsa ntchito zida zapamwamba za semiconductor, ma diode a Guangmin akadali okwera mtengo kwambiri pazowunikira zambiri. M'zaka 10 zapitazi, mtengo wa zida za semiconductor watsika kwambiri. Komabe, pansi pakugwiritsa ntchito mokulirapo, ma diode a Guangmin ndi njira yowunikira yotsika mtengo. Posachedwapa, ma diode a Guangmin atenga gawo lalikulu paukadaulo wapadziko lonse lapansi. LED imapangidwa ndi PN, ngati diode wamba, ndipo imakhala ndi njira imodzi yoyendetsera. Pambuyo powonjezera mpweya wabwino pa diode ya Guangmin, ma elekitironi mu nage m'dera la N kuchokera ku P ndi electron m'dera la P kuchokera ku dera la n, ndi zamagetsi ndi phanga lopanda kanthu m'dera la PN mu mfundo ya PN. mu ma microns angapo pafupi ndi mfundo ya PN, motsatira Compound, imapanga kuwala kodziwikiratu. Kutengera kusiyana kwa zida za semiconductor, mphamvu yamagetsi ndi ma cavities ndi yosiyananso. Ndi mphamvu zingati zomwe zimatulutsidwa pamene magetsi ndi mabowo akuphatikizidwa. Pamene imatulutsa mphamvu zambiri, imafupikitsa kutalika kwa mawonekedwe a kuwala. The ambiri ntchito diodes wofiira, wobiriwira kapena wachikasu.
