Kodi mfundo yowunikira magetsi a LED ndi iti?

Kodi mfundo yowunikira magetsi a LED ndi iti? Nyali ya LED ndi electroluminescent semiconductor material chip, yomwe imachiritsidwa pa bulaketi ndi guluu siliva kapena guluu woyera, ndiyeno olumikizidwa kwa Chip ndi bolodi dera ndi mawaya siliva kapena golide, ndi losindikizidwa ndi epoxy utomoni mozungulira kuteteza wamkati pachimake waya. Kugwira ntchito, chipolopolocho chimayikidwa komaliza, kotero kukana kwamphamvu kwa nyali ya LED ndikwabwino. 1. Kapangidwe ka mikanda ya nyali Chimodzi mwazinthu zofunika kwambiri zopangira kuwala kwa nyali za LED (Light Emitting Diode) ndi mkanda wa nyali wa kukula kwa nyemba za mung mkati mwa nyaliyo. Ngakhale kukula kwake kuli kochepa, ntchito yake si yaying'ono.

Titayang'ana pa kapangidwe ka mkanda wa nyali ya LED, tipeza chophatikizira chofanana ndi njere ya sesame. Mapangidwe a chip ndi ovuta kwambiri, ndipo amagawidwa m'magulu angapo: chapamwamba cha Z chimatchedwa P-mtundu wa semiconductor wosanjikiza, chapakati ndi chotulutsa kuwala, ndipo chapansi cha Z chimatchedwa N-mtundu wa semiconductor wosanjikiza. Ndiye, kodi kuwala kwa LED kumatulutsidwa bwanji? 2. Mfundo ya kutulutsa kuwala Kuchokera pamalingaliro a thupi: pamene magetsi akudutsa mu chowotcha, ma electron mu semiconductor ya mtundu wa N ndi mabowo a semiconductor amtundu wa P amawombana mwamphamvu ndikuphatikizananso muzitsulo zotulutsa kuwala kuti apange ma photons, omwe amatulutsa mphamvu mu mawonekedwe a photons (ndiko kuti, kuwala komwe mukuwona).

LED LED imatchedwanso kuwala emitting diode, voliyumu yake ndi yaying'ono kwambiri komanso yosalimba kwambiri, sikoyenera kugwiritsa ntchito mwachindunji. Choncho mlengiyo anawonjezera chigoba chodzitetezera n’kuchisindikiza mkati, motero n’kupanga mkanda wosavuta kugwiritsa ntchito nyali ya LED. Mukalumikiza mikanda yambiri ya nyali ya LED palimodzi, nyali zingapo za LED zitha kupangidwa.

3. Magetsi a LED a mitundu yosiyanasiyana Ma semiconductors a zipangizo zosiyanasiyana adzatulutsa mitundu yosiyanasiyana ya kuwala, monga kuwala kofiira, kuwala kobiriwira, kuwala kwa buluu ndi zina zotero. Komabe, palibe zida za semiconductor zomwe zimatha kutulutsa kuwala koyera mpaka pano. Koma kodi mikanda yoyera ya LED yomwe timagwiritsa ntchito nthawi zambiri imapangidwa bwanji? 4. Mbadwo wa nyali zoyera za LED Pano tiyenera kutchula wopambana wa Nobel - Dr. Shuji Nakamura.

Anapanga LED ya buluu, yomwe inayalanso maziko ena a LED yoyera. Malingana ndi chothandizira chachikulu ichi, adapatsidwa mphoto ya Nobel mu Physics mu 2014. Ponena za momwe ma LED a buluu amasinthidwa kukhala ma LED oyera, chifukwa chachikulu ndikuti pali phosphor yowonjezera mu chip.

Mfundo yayikulu yotulutsa kuwala sikunasinthe kwambiri: Pakati pa zigawo ziwiri za semiconductor, ma elekitironi ndi mabowo amawombana ndikuphatikizananso kuti apange mafotoni abuluu pagawo lotulutsa kuwala. Gawo la kuwala kwa buluu komwe kumapangidwa kumadutsa mu zokutira fulorosenti ndi kutulutsidwa mwachindunji; gawo lotsala lidzagunda chophimba cha fulorosenti ndikulumikizana nacho kuti apange mafotoni achikasu. Kuwala koyera kumapangidwa pophatikiza (kusakaniza) mafotoni abuluu ndi mafotoni achikasu.

Pakalipano, mitundu yogwiritsira ntchito nyali za LED ndizofala kwambiri. Kutengera chitsanzo cha Xinshengkai Optoelectronics, mizere yowunikira ya LED yomwe imapangidwa ndi iyo imagwiritsidwa ntchito kwambiri pakukongoletsa m'nyumba ndi kunja, mawonekedwe amisewu, zowerengera zodzikongoletsera, minda, magalimoto, maiwe, zikwangwani zotsatsa, mahotela, malo ogulitsira, KTV, malo opumira, ndi zina zambiri.
