Kukhazikitsidwa kwa zowoneka bwino zopepuka

Kukhazikitsidwa kwa zowoneka bwino zopepuka

Mafuta owunikira (matikini, ndipo timatchulanso monga IR LED) ndi zida semiconduct zomwe zimapangitsa kuwala komwe kumapangitsa kuti zikhalepo. Izi zidapangitsa kuti kumenyedwa ndi kutsogozedwa kwakhala chinthu chofunikira kwambiri pamapulogalamu osiyanasiyana, kuphatikizapo zowongolera zakutali, machitidwe, zida zolumikizirana, ndi zida zamasiku onse. Tidzauza tanthauzo lake, kapangidwe kake, kuyeseza, machitidwe, ndi kugwiritsa ntchito kwa matikiti aboma mwatsatanetsatane.

Kutanthauzira kwa ma doodid owunikira (ma LED). Kutsogoleredwa kofikiridwa ndi mtundu wa dazi yowunikira yomwe imatulutsa kuwala kudera la infrared kuwonekera kwa electromagram. Wokondedwa wa infrarem umakhala ndi ma nanometers (nM) mpaka 1 millimeter (mm) ku Hufleth, kupitirira kumapeto kochepa kwa mawonekedwe owoneka. Maupangiri a matikidwe amapangidwa makamaka kuti atulutse kuwala m'njira izi, ndikuwapangitsa kukhala osawoneka ndi maso owoneka bwino koma odziwika ndi ma virus.

Kupanga kwa Maupangiri Osiyanasiyana

Ma LED A MALANGIZO OTHANDIZA (izi zikuphatikiza 940nm LED, 850nm LED, 730nm Drond ect ect. Zipangizo zomwe zimagwiritsidwa ntchito kwambiri semiconductor zomwe zimagwiritsidwa ntchito kwambiri m'magawo operewera ndi gallium arnide (Gaas), gallium arsenation phosphide (Gaasp), ndi gallium aluminiya (Gaalas). Zipangizozi zimasankhidwa kuti zizitha kuyatsa kuwala kwamomwe zimawonetsedwa ndi mawonekedwe awo opanga ma LED.Njira yomwe yaperekedwa imakhala ndi zigawo zingapo za semiconductor zida za semonictoctor. Kapangidwe koyambirira kamaphatikizira n-mtundu semiconductor yosanjikiza ndi mtundu wa p-mtundu wa p-squiconductor yosanjikiza, yolekanitsidwa ndi gawo lodziwika lomwe limadziwika kuti ndi dera logwira ntchito. Mphamvu yamphamvu ikagwiritsidwa ntchito kudutsa ma electrons, ma elekitoni ndi mabowo omwe amagwiranso ntchito kudera logwira, kumasulira mphamvu mu mawonekedwe a zithunzi. Mphamvu za zithunzizi zimagwirizana ndi mawonekedwe a mafunde a kuwala komwe adatulutsa, komwe momwe zimakhalira ndi marowa omwe aperekedwa mkati mwa infrarem.

Kugwira Mfundo Ya Ma LED

Mfundo yogwira ntchito ya kutsogoleredwa imachokera pazinthu za pa Eleomenon wa Elecroulumines, pomwe kutulutsa kumachitika chifukwa chakubwezeretsanso onyamula (ma electrons ndi mabowo). Pamene magetsi oyandikana nawo am'madzi akagwiritsidwa ntchito pa PNGRET a PNSCECE cha DED mawonekedwe a zithunzi. Mphamvu yazomwe zimapangitsa kuti Semicoctoct ya semiconductor ya zikuluzikulu zimazindikira kuwala kwa kuwala. Pankhani ya matopu operekedwa, bandgap yakonzedwa kuti ipange kuwala kwamomwe mwaonekera, komwe sikuwoneka kwa diso la munthu koma chitha kupezeka ndi masensa ophatikizika.

Makhalidwe a matikiti am'maso

Ziwonetsero zamitundu yodziwikiratu zimawonetsa mikhalidwe ingapo yomwe imawapangitsa kukhala oyenera pakugwiritsa ntchito mitundu yambiri. Zina mwazofunikira za marongo a marongo omwe aperekedwe: 1. Mitundu ya Hiplength: Mautsowa a Enterrated Enter Etwala kuwala komwe kumachitika, kuyambira 700 nanometers mpaka 1 millimeter kuvelength. Mphepo inayake yomwe idatulutsidwa ndi yofinya imatengera semicotoctor zinthu zomwe zimagwiritsidwa ntchito pomanga .2. Kuchita bwino: Madambo ofala amakhala othandiza kwambiri kutembenukira mphamvu zamagetsi kukhala mphamvu zopepuka. Kuchita bwino kumeneku ndikofunikira kwambiri pakugwiritsa ntchito komwe kumwa mphamvu ndi nkhawa, monga zida zonyamula kapena ma stript.3. Lifeispan: matikiti ophatikizika amakhala ndi moyo wautali, kuyambira maola 50,000 mpaka 100,000 akupitiliza kugwira ntchito. Mphamvu yokhotayi imawapangitsa kukhala abwino pazogwiritsa ntchito komwe kukonza kapena kubwezeretsa kumakhala kovuta kapena kovuta.4. Ntchito yomweyo: Maupangiri ophatikizika amakhala ndi nthawi yoyankha mwachangu, kutanthauza kuti amatha kuyaka ndikuwasiya nthawi yomweyo. Khalidwe ili ndiyofunikira pakugwiritsa ntchito yomwe imafuna kusinthasintha kapena kusintha kwa magetsi. Malangizo: Maupangiri a Maumenti adawala bwino pamtengo wowongolera, ndikuwapangitsa kukhala oyenera pakugwiritsa ntchito pomwe kulongosoka kolondola kwa gwero lopepuka ndikofunikira. Kutulutsa kumeneku kungakulimbikitsenso kugwiritsa ntchito mandala owala kapena owonetsera.

Mapulogalamu a ma LED

Maupangiri operekedwa amapezeka kuti amagwiritsa ntchito pogwiritsa ntchito magawo osiyanasiyana pamakampani osiyanasiyana. Ena mwa mapulogalamu ofunikira a marontrared amaphatikizapo: 1. Zowongolera zakutali: matikiti aboma amagwiritsidwa ntchito poyendetsa ma TV, zowongolera mpweya, ndi zida zina zamagetsi. Kuwala kotulutsidwa ndi LED kumanyamulidwa ndi sensor mu chipangizocho, kulola kulumikizana mwa zingwe ndi kuwongolera.2. Njira Zotetezera: Zigawo zamitundu zomwe zili ndi gawo limodzi la machitidwe otetezeka, monga makamera owunikira ndi masensa. Kuwala kopanda tanthauzo sikuwoneka kwa diso la munthu koma kumatha kupezeka ndi makamera okhala ndi ma seyrared eyrant, kupangitsa chidwi cha masomphenya usiku .3. Zipangizo zolankhulirana: Zida zolumikizirana zimagwiritsidwa ntchito polumikizirana kwa maoneke potumiza zingwe zopanda zingwe zapafupi. Kuwala kwa infrated kumatha kunyamula zizindikiro zomwe zimasokoneza zizindikiro za ailesi yazinsinsi, kupangitsa kukhala koyenera kulumikizana kwamapulogalamu.4. Ntchito zamagetsi: Maupangiri ophatikizidwa amagwiritsidwa ntchito kwambiri pamapulogalamu agalimoto, monga ma sensor oyandikira, magetsi, ndi kuyatsa kwamkati. Ma sensore ophatikizika amatha kudziwa zinthu zomwe zili mgalimoto ndikuthandizira pakuthandizira poimikapo makina .5. Zipangizo zamankhwala: Madambo ofala amagwiritsidwa ntchito m'magawo azachipatala pazogwiritsa ntchito monga Phototherapy, mafuta okometsera mafuta, ndi maganizidwe. Kutha kwa kuwala kolowera minofu kumapangitsa kuti ikhale yofunika kwambiri kwa njira zosagwiritsidwira ntchito zachipatala .6. Makina Othandizira: Madambo ophatikizidwa amagwiritsidwa ntchito mu makina opanga mafakitale a ntchito monga kuwonekera kwa chinthu, udindo wa kumverera, komanso kusanthula barcode. Kudalirika ndi kuthamanga kwa masensa operewera kuwapangitsa kukhala oyenera kupanga ndi mapulogalamu ndi mapulogalamu.

Mapeto

Zowonjezera zopepuka (ma LED) ndi zida semiconduct zomwe zimapangitsa kuwala kwamomwe kumapangitsa kuti akhale owoneka bwino, kuwapangitsa kukhala ofunika kwa mapulogalamu osiyanasiyana omwe amafunikira magwero osawoneka bwino. Kuphatikizidwa, mfundo zogwirira ntchito, zomwe zimagwiritsidwa ntchito, ndipo kugwiritsa ntchito madambo a infrared zimawapangitsa kukhala chinthu chosasinthika komanso chothandiza, kugwiritsa ntchito ukadaulo, zomwe zimapangitsa kuti magwero azikhala oyenera komanso odalirika Monga ma forod a ma LED akuyembekezeka kukula. Mwa kumvetsetsa mfundo zofunika kwambiri za matikidwe a infrared, mainjiniya ndi ofufuza atha kupitiliza kupanga matekinoloje atsopano omwe amawunikira zowunikira zingapo.
