Iko kuiswa kwekusvitswa kwechiedza-kubereka diode

Infrared Light-Embiting Diodes (LED, uye isu titumidza zita seI LED) AS SEMICONDURIRA ANOGONESESA MUFANANIDZO ZVINOGONESA KUTI VAVANZE KUTI VAVANZE KUTI VAVANZE KUTI VAVANZE KUTI VAVANZE KUTI VANZVI PAMUSORO PAKUTI. Aya Smd anotungamirwa uye dip Tichataura kududzirwa, kuumbwa, basa rekushanda, hunhu, uye zvikumbiro zvevakanyorwa maLD zvakadzama zvakadzama.

Tsanangudzo ye infrared mwenje-inoburitsa diodes (LES). Chinyorwa chinotungamirwa ndirwo rudzi rwechiedza-inoburitsa diode inoburitsa mwenje munzvimbo infrared yeiyo electromagnetic spectrum. Iyo infrared spectrum kazhinji kubva pamativi emakore makumi manomwe nematanhatu Infrared L.ds yakagadzirirwa kunyatsojeka kuti ibvise mwenje mune izvi huwandu, uchiita kuti vasoneke pazana rakashama asi vanoona nevanonzi vanonzwa uye makamera.

Kuumbwa kweVanhu Vakasanganiswa

Infrared Lels (izvi zvinosanganisira 940nm inotungamirwa, 850nm inotungamirwa, 1050nm Loter, 1550nm LED, 1550nm LED, Izvo zvinonyanya kushandiswa Semiconductor zvinhu muInfrared LEDS are gallium Arsenide (Gallium Arsenide (Galasp), uye Gallium Aluminium Arsenide (Gallas). Izvi zvinhu zvinosarudzwa pakukwanisa kwavo kusimudzira chiedza muInfrared spectrum uye kuwirirana kwavo nemaitiro ekugadzira mitezo.Kugadzira kwezvinhu zvakatungamirwa kune zvikamu zvakati wandei zveMicononductor zvinhu. Chimiro chakanyanya kukosha chinosanganisira n-type semiconductor layer layer uye p-mhando semicononductor layer, yakaparadzaniswa nejhizha rinozivikanwa sedunhu rinoshanda. Kana iyo yekumberi voltage yakaiswa mhiri kwePN Junction, maElectrons uye maburi anodzoreredza munzvimbo inoshanda, kusunungura simba muchimiro chemapikicha. Simba remafananidzo aya anoenderana neyekuwona kweiyo yakabuda mwenje, iyo mune nyaya yemisangano yezvinhu inodonha mukati meiyo infrared spectrum.

Kushanda nheyo yekubvisirwa maLED

Nheyo yekushanda yakavanzika inotungamirwa kubva pane imwe nyaya yeiyo Electrouminescence, uko kubviswa kwechiedza kunoitika nekuda kwekudzorera kwemutakuri (elecrons nemakomba) mune semiconductor zvinhu. Kana chifambiso cheBasoas Voltage inoiswa kune iyo PN Junction yeiyo N-TELESS Dunhu reP-THE RINOGONESWA KUNYANYA KUNYANYA fomu yemapikicha. Iyo Energy Bandgap yeiyo Semiconductor zvinhu zvinosarudza iyo wavelength yeiyo yakabuda mwenje. Panyaya yemisangano yeLeds, iyo bandgap yakagadzirirwa kubuda pachena mune infrared spectrum, iyo isingaonekwi neziso remunhu asi rinogona kuonekwa nevanzwi nemasendas nekamera.

Hunhu hwezvinyorwa zvisingabvumirwe

Infrared Lels inoratidza zvakati wandei maitiro anovaita kuti vakwanise kukwana kune dzakasiyana siyana dzekushandisa. Mamwe maitiro akakosha ezvinyorwa zvisingaverengeki zvinosanganisira: 1. Wavelength Bhuronzi: Infrared Lels Bvisa Chiedza muInfrared Spectrum, kazhinji kubva ku700 nanometers kusvika 1 millimeter mune wavelength. Iyo yakasarudzika wavelength yakavezwa neiyo infrared inotungamirwa zvinoenderana neyeMiconductor zvinhu zvinoshandiswa mukuvaka kwayo.2. Kubudirira: Infrared LEDs inoshanda zvakanyanya mukushandura simba remagetsi kuita simba renje. Kubudirira uku kwakakosha kune zvekushandisa uko kushandiswa kwesimba kunonetsa, senge mune zvinotakurirwa zvishandiso kana bhatiri-inoshanda system.3. LikeSpan: Infrared LEDs ane hupenyu hwakareba, kazhinji kubva pamakumi mashanu kusvika maawa kusvika zviuru zana ekuenderera mberi kushanda. Iyi longevity inovaita inokodzera kuti inyatsoita magadzirirwo aunogadziriswa kana kutsiva kwakaoma kana kunodhura.4. Kupindirana kwepamhepo: Infrared LED ane nguva yekukurumidza kupindura, zvichireva kuti vanokwanisa kuvhura uye kubva kunenge pakarepo. Hunhu uhwu hunokosha kuti zvikumbiro zvinoda kukurumidza kujaira kana kuchinjika kweiyo mwenje wechiedza.5. Kutungamira: Infrared Lels Erump Chiedza mugwara redanda, zvichiita kuti vakwanise kunyatsoita kuti zvibodzwa zvinofanirwa kuve neyakagadziriswa kwechiedza chinodiwa. Iyi nzira yekuburitsa inogona kuwedzeredzwa nekushandiswa kwemashoko ezvinyorwa kana zviratidzo.

Zvikumbiro zveVanonzi LeDs

Infrared LESS inowana yakasarudzika kushandiswa mune dzakasiyana-siyana zvikumbiro pamisango yakasiyana. Zvimwe zvezvakakosha zvekushandisa zvevanonzi maLed zvinosanganisira: 1. Remote Control: Infrared LDS inowanzo shandiswa mumidziyo yekudzora terevhizheni, mhepo inogadzira, uye mamwe magetsi emidziyo. Iyo infrared mwenje yakapihwa neiyo LED inotorwa neiyo sensor mune yekugamuchira chishandiso, ichibvumira kutaurirana isina waya uye kudzora.2. Systems Systems: Infrared LDS chikamu chakakosha chehurongwa hwekuchengetedza, sekuti semakamera ekuongorora uye kufamba sensors. Infrared mwenje usingaonekwe neziso remunhu asi inogona kuwonekwa nemakamera akavezwa nevanonzi vanonzwika sensors, inogonesa usiku maonero ekugona.3. Misangano yekutaurirana: Infrared LEDs inoshandiswa mune Optical kutaurirana masisitimu ekuendesa data isina waya pane pfupi marefu. Infrared mwenje inogona kutakura masaini e data idzo dzisingadzivisiki dzekuvhiringidza kubva kuRadio Frequency masaini, zvichiita kuti zviite zvakaringana zvekutaurirana kwekutaurirana.4. Zvekushandisa Zvemotokari: Infrared LEDs inowedzera inoshandiswa mune zvemotokari zvinoshandiswa, sekusangana kwepfungwa, brake mwenje, uye mwenje wemukati. Infrared sensors inogona kuona zvinhu zviri mumotokari dzakapoteredzwa uye dzinobatsira mukupaka rubatsiro systems.5. Zvishandiso zvekurapa: Infrared LEDs anoshandirwa mune zvishandiso zvekushandisa zvekushandisa senge PhotoTherapy, kuongororwa kweropa kweropa, uye kufungidzira kwekufungidzira. Kugona kweiyo infrared mwenje kuti ive mitezo inopinda inoita kuti ive yakakosha kune isiri-inosanganisa maitiro.6. Industrial auto: Infrared LEDs inoshandiswa muindasitiriti emaindasitiriti emaindasitiriti emabasa akadai sekuona kwechinhu, chinzvimbo chekunzwa, uye barcode kuongorora. Kuvimbika uye kumhanya kwekusanzwisiswa sensors kunovaita vakanyatsokodzera kuti vagadzire uye vaone zvinhu.

Mhedziso

Infrared Light-Embiting Diodes (LEDS) AS SEMICONDURActor zvishandiso zvinosimbisa muvhenekeri muNefrared spectations Kuumbwa, hunhu hwekushanda, hunhu, uye zvekushandisa zvevhu zvakashata zvinoita kuti vave nenhandare dzakasiyana siyana, kusanganisira zvemagetsi, uye kuchengetedzeka. Semukati marobvu mafero anotarisirwa kukura. Nekunzwisisa nheyo dzakakosha uye mainjiniya maLeds, mainjiniya uye vatsvagiri vanogona kuramba vachikura uye kugadzira matekinoroji matsva ekuti zvinhu zvakasarudzika zvechiitiko chakabatanidzwa nekuda kwekushandisa kwakasiyana siyana.
