Inzwa yezithombe

Inzwa ye-Photosensitive iyinzwa ye-elekthronikhi ekahle engakwazi ukulawula ukushintshwa okuzenzakalelayo kwesekhethi ngenxa yokushintsha kokukhanya ekuseni nokumnyama (ukuphuma nokushona kwelanga).Inzwa ye-photosensitive ingalawula ngokuzenzakalelayo ukuvulwa nokuvala kweIzibani zokukhanyisa ze-LEDngokwesimo sezulu, isikhathi nendawo.Ezinsukwini ezikhanyayo, ukusetshenziswa kwamandla kuncishiswa ngokunciphisa amandla awo okukhipha.Uma kuqhathaniswa nokusetshenziswa kwezibani ze-fluorescent, isitolo esinendawo engamamitha-skwele angama-200 singanciphisa ukusetshenziswa kwamandla ngo-53% kakhulu, futhi impilo yesevisi cishe amahora angama-50000 ~ 100000.Ngokuvamile, impilo yesevisi yezibani zokukhanyisa ze-LED cishe amahora angu-40000;Umbala wokukhanya ungashintshwa futhi ku-RGB ukuze wenze ukukhanya kube nemibala eminingi kanye nomkhathi usebenze kakhulu.

Inzwa ye-infrared

Inzwa ye-infrared isebenza ngokuthola i-infrared ekhishwa umzimba womuntu.Umgomo oyinhloko uthi: Izikhathi eziyi-10 zokuphuma komzimba womuntu μ Ireyi ye-infrared engaba ngu-M ithuthukiswa ilensi yesihlungi seFresnel futhi iqoqwe kumtshina we-PIR element ye-pyroelectric.Lapho abantu benyakaza, indawo yokukhishwa kwemisebe ye-infrared izoshintsha, isici sizolahlekelwa ibhalansi yokushaja, sikhiqize umphumela we-pyroelectric futhi sikhulule ukushaja ngaphandle.Inzwa ye-infrared izoguqula ukuguqulwa kwamandla emisebe ye-infrared ngokusebenzisa ilensi yesihlungi seFresnel ibe isignali kagesi, ukuguqulwa kwe-Thermoelectric.Uma ungekho umzimba womuntu onyakazayo endaweni yokutholwa komtshina we-infrared, inzwa ye-infrared izwa izinga lokushisa elingemuva kuphela.Lapho umzimba womuntu ungena endaweni yokuthola, nge-Fresnel lens, inzwa ye-infrared ye-pyroelectric izwa umehluko phakathi kwezinga lokushisa lomzimba womuntu kanye nezinga lokushisa elingemuva, Ngemva kokuba isignali iqoqwe, iqhathaniswa nedatha yokuthola ekhona ohlelweni ukuze ihlulele. noma ngabe othile kanye neminye imithombo ye-infrared ingena endaweni yokuthola.

Ukukhanya Kwenzwa Yokunyakaza kwe-LED

Inzwa ye-ultrasonic

Izinzwa ze-Ultrasonic, ezifana nezinzwa ze-infrared, ziye zasetshenziswa kakhulu ekutholeni ngokuzenzekelayo izinto ezihambayo eminyakeni yamuva.Inzwa ye-ultrasonic ikakhulukazi isebenzisa isimiso se-Doppler ukuze ikhiphe amagagasi e-ultrasonic anemvamisa ephezulu adlula umbono womzimba womuntu nge-crystal oscillator.Ngokuvamile, igagasi elingu-25 ~ 40KHz liyakhethwa, bese imojuli yokulawula ithola imvamisa yegagasi elibonisiwe.Uma kukhona ukunyakaza kwezinto endaweni, imvamisa yegagasi ebonisiwe izoguquguquka kancane, okungukuthi, umphumela we-Doppler, ukuze ihlulele ukunyakaza kwezinto endaweni yokukhanyisa, Ukuze ulawule ukushintshwa.

Inzwa yezinga lokushisa

Inzwa yokushisa ye-NTC isetshenziswa kabanzi njengokuvikela izinga lokushisa elingaphezulu kweI-LEDizibani.Uma umthombo wokukhanya we-LED wamandla aphezulu wamukelwa kumalambu e-LED, kufanele kwamukelwe irediyetha ye-aluminium enamaphiko amaningi.Ngenxa yesikhala esincane sezibani ze-LED zokukhanyisa kwangaphakathi, inkinga yokukhishwa kokushisa isengenye yezinkinga ezinkulu zobuchwepheshe okwamanje.

Ukungashisi kahle kwezibani ze-LED kuzoholela ekuhlulekeni kokukhanya kwangaphambi kwesikhathi komthombo wokukhanya we-LED ngenxa yokushisa ngokweqile.Ngemuva kokuba isibani se-LED sivuliwe, ukushisa kuzocetshiswa ku-cap yesibani ngenxa yokukhuphuka okuzenzakalelayo komoya oshisayo, okuzothinta impilo yesevisi yokunikezwa kwamandla.Ngakho-ke, lapho uklama izibani ze-LED, i-NTC ingaba seduze nerediyetha ye-aluminium eduze nomthombo wokukhanya we-LED ukuze iqoqe izinga lokushisa lezibani ngesikhathi sangempela.Lapho izinga lokushisa le-radiator ye-aluminium yenkomishi yesibani likhuphuka, lesi sifunda singasetshenziswa ukunciphisa ngokuzenzakalelayo ukukhishwa kwamanje komthombo wamanje wamanje ukupholisa izibani;Lapho izinga lokushisa le-radiator ye-aluminium yenkomishi yesibani likhuphuka linani lokusetha umkhawulo, ukunikezwa kwamandla kwe-LED kuyavalwa ngokuzenzakalelayo ukuze kubonakale ukuvikelwa kwezinga lokushisa ngaphezulu kwesibani.Lapho izinga lokushisa lehla, isibani sivulwa ngokuzenzakalelayo futhi.

Inzwa yezwi

Inzwa yokulawula umsindo iqukethe inzwa yokulawula umsindo, i-amplifier yomsindo, isifunda sokukhetha isiteshi, ukulibaziseka kokuvula isifunda kanye nesifunda sokulawula i-thyristor.Yahlulela ukuthi ungaqala yini ukujikeleza kokulawula ngokusekelwe emiphumeleni yokuqhathanisa yomsindo, futhi usethe inani langempela lenzwa yokulawula umsindo ngesilawuli.Inzwa yokulawula umsindo ihlale iqhathanisa ukushuba komsindo wangaphandle nenani langempela, futhi idlulisela isignali "yomsindo" esikhungweni sokulawula lapho idlula inani lokuqala.Inzwa yokulawula umsindo isetshenziswa kakhulu emaphasishi nasezindaweni zokukhanyisa zomphakathi.

Inzwa yokungeniswa kwe-microwave

Inzwa yokungeniswa kwe-Microwave ingumtshina wezinto ezihambayo oklanywe ngokusekelwe kumgomo womphumela we-Doppler.Ithola ukuthi indawo yento ihamba ngendlela okungeyona yokuxhumana, bese ikhiqiza ukusebenza kweswishi okuhambisanayo.Lapho othile engena endaweni yezinzwa futhi efinyelela isidingo sokukhanyisa, iswishi yezinzwa izovuleka ngokuzenzakalelayo, into esetshenziswayo yokulayisha izoqala ukusebenza, futhi uhlelo lokulibaziseka luzoqalwa.Uma nje umzimba womuntu ungashiyi indawo yokuzwa, into esetshenziswayo yokulayisha izoqhubeka nokusebenza.Lapho umzimba womuntu ushiya indawo yezinzwa, inzwa iqala ukubala ukubambezeleka.Ekupheleni kokulibaziseka, iswishi yenzwa ivaleka ngokuzenzakalelayo futhi into esetshenziswayo iyayeka ukusebenza.Iphephe ngempela, ilula, ihlakaniphile futhi yonga amandla.
