Ngokuthuthuka kwezinga lokuphila kwabantu, imindeni eminingi isiqala ukufakwaukukhanya okuhlakaniphileamasistimu ngesikhathi sokuhlobisa ukunikeza izinsizakalo ezisezingeni eliphezulu nezinethezekile.Amasistimu okukhanyisa asekhaya ahlakaniphile angathuthukisa ikhwalithi yezindawo zokukhanyisa ezihlala futhi agxile ngokuphelele kubantu.Kucatshangelwa ngokugcwele imiphumela ebonwayo yabantu, futhi kucatshangelwa "isifo sonyaka" esibangelwa ukuncishiswa kokukhanya kwesizini, ukuze kwakhiwe indawo yokuhlala yomuntu siqu, yobuciko, entofontofo nenhle, kodwa uhlelo lokukhanyisa belulokhu luyisimo esivamile. Izinto ezibalulekile zokusebenzisa amandla njengamanje zihlushwa imfucuza engathi sína, ngakho-ke ukuthuthukiswa kokukhanyisa okuhlakaniphile kubaluleke kakhulu.

Ubuchwepheshe obune bokulawula beukukhanya okuhlakaniphile:

Ukukhanyisa kwesilawuli kude:Izinto zokukhanyisa zilawulwa ngamasignali omsakazo.Ungasebenzisa iklayenti leselula ukulawula ukude iswishi, futhi ezinye zifakwe amasokhethi nama-transmitter uma uzithenga.

Inzwa ye-infrared:Ngokuthwebula imisebe ye-infrared yamaza obude obuthile ukuze ulawule ukukhanya nokucisha izibani, ukukhanya okubambezelekile kungafinyelela umphumela "wokukhanyisa uma abantu beza futhi kukhanye lapho abantu behamba".

Ukukhanyisa okuhlanganisiwe:Namuhla, ukukhanya okuhlanganisiwe okuhlanganiswe nemithombo eminingi yokukhanya sekuthuthuke ngokuvuthwa kakhulu, futhi zombili izigcawu nokukhanya kombala kungahlanganiswa ngokukhululekile.

Ukukhanya kokuthinta:Ukushintsha kwamandla kubangelwa ukuthinta kweminwe ukulawula amalambu.I-insulation kanye nezici ezingangeni manzi zifanele izindlu zokugezela, amakhishi nezinye izindawo.

Imisebenzi eyisithupha emikhulu yeukukhanya okuhlakaniphile:

1. Umsebenzi wokulawula isikhathi ikuvumela ukuba ulungise ngokukhululekile isikhathi sokushintsha ukukhanya, njengoba ukhetha futhi usisebenzisa, futhi kuzokusebenzela ngaso sonke isikhathi.

2. Ukulawula okuphakathi nendawo nokusebenza kwamaphuzu amaningi: Itheminali kunoma iyiphi indawo ingalawula izibani ezindaweni ezahlukene;noma amatheminali ezindaweni ezahlukene angalawula ukukhanya okufanayo.

3. Isebenza ngokugcwele, icishiwe futhi inkumbulo.Izibani zalo lonke uhlelo lokukhanyisa zingavulwa futhi zicishwe ngokugcwele ngokuchofoza okukodwa.Asikho isidingo sokucindezela izinkinobho ngayinye ngayinye ukuze ucime noma ukhanyise izibani, unciphise izinkinga ezingadingekile.

4. Izilungiselelo zesigcawu zisetha imodi ehleliwe, futhi zingalawulwa ngokuchofoza okukodwa ngemva kokuhlela kanye.Noma khetha izilungiselelo zamahhala, zinikeze imisebenzi eyengeziwe ngokwezidingo zakho siqu, futhi ulawule ikhaya lakho ngemibono yakho.

5. Umsebenzi wokuqalisa othambile: Lapho ukukhanya kukhanyisiwe, ukukhanya kushintsha kancane kancane kusuka kokumnyama kuye kokukhanyayo.Lapho ukukhanya kucishiwe, ukukhanya kushintsha kancane kancane kusuka kokukhanyayo kuye kokumnyama.Lokhu kuvimbela izinguquko ezingazelelwe ekukhanyeni ekucasuleni iso lomuntu, kunikeze isivimbeli seso lomuntu nokuvikela amehlo.Iphinde igweme umthelela wokushintsha okungazelelwe kumazinga okushisa aphezulu amanje kanye naphezulu kumcu, ivikele isibani, futhi inwebe impilo yesevisi.Kungakhanyisa kancane ukukhanya lapho abantu besondela kuyo, futhi kufiphale kancane kancane njengoba umuntu ehamba, okonga ugesi ngempumelelo.

6. Umsebenzi wokulungisa ukukhanya kokukhanyisa Kungakhathaliseki ukuthi wenza siphi isigcawu, ungakwazi ukulungisa imodi yesehlakalo nokukhanya kokukhanyisa okufunayo ngokuya ngesibhedlela sakho.Ukukhanya okuhlukile kungalungiselwa ukwamukela izivakashi, amaphathi, amamuvi, nokufunda.Ukukhanya okuncane nokumnyama kukusiza ukuthi ucabange, kuyilapho ukukhanya okuningi nokugqamayo kwenza umkhathi ube nomdlandla kakhulu.Le misebenzi ilula kakhulu.Ungacindezela futhi ubambe iswishi yasendaweni ukuze ukhanyise futhi ufiphaze ukukhanya, noma ungasebenzisa isilawuli esiphakathi nendawo noma isilawuli kude ukuze ulungise ukukhanya kokukhanya ngokucindezela nje inkinobho eyodwa.

Izinzwa zokukhanya kwe-ambient ikakhulukazi zakhiwe ama-elementi e-photosensitive.Izingxenye ze-Photosensitive zikhula ngokushesha, ngezinhlobonhlobo ezihlukahlukene kanye nokusetshenziswa okubanzi.Inzwa yokukhanya kwe-ambient ingakwazi ukuzwa izimo zokukhanya ezizungezile futhi itshele i-chip yokucubungula ukuthi ilungise ngokuzenzakalelayo ukukhanya kokukhanya kwangemuva ukuze kwehlise ukusetshenziswa kwamandla omkhiqizo.Isibonelo, ezinhlelweni zeselula ezifana nomakhalekhukhwini, izincwadi zokubhalela, namathebulethi, isibonisi sisebenzisa kufika ku-30% wawo wonke amandla ebhethri.Ukusetshenziswa kwezinzwa zokukhanya kwe-ambient kungandisa isikhathi sokusebenza sebhethri.Ngakolunye uhlangothi, inzwa yokukhanya kwe-ambient isiza isibonisi ukuletha isithombe esithambile.Uma ukukhanya kwe-ambient kuphezulu, isibonisi se-LCD sisebenzisa inzwa yokukhanya kwe-ambient sizozivumelanisa ngokuzenzakalelayo nokukhanya okuphezulu.Uma indawo yangaphandle imnyama, isibonisi sizolungiselelwa ekukhanyeni okuphansi.Inzwa yokukhanya kwe-ambient idinga ifilimu enqanyuliwe ye-infrared ku-chip, noma ngisho nefilimu enephethini yokusika kwe-infrared enamathiselwe ngokuqondile ku-wafer ye-silicon.

I-WH4530A eyethulwe yi-Taiwan Wanghong iyinzwa yebanga elilula ehlanganisa inzwa yokukhanya okuzungezile (ALS), inzwa ye-proximity (PS) kanye nokukhanya okuphezulu kwe-infrared LED ibe yinye;ububanzi bungalinganiswa kusuka ku-0-100cm;Isebenzisa isixhumi esibonakalayo se-I2C, ingafinyelela imisebenzi efana nokuzwela okuphezulu kakhulu, ububanzi obunembayo kanye nobubanzi bokutholwa okubanzi.

Le chip ixazulula ukushiyeka kwezinzwa eziseduze ze-infrared, i-ultrasonic nefrikhwensi yomsakazo njengokuzwela okuphansi, isivinini sokuphendula esinensayo, ukwethembeka okuphansi, kanye nokusetshenziswa kwamandla okuphezulu.Yamukela ukwakheka kwekhwalithi ephezulu, okwenza inzwa yokusondela ibencane ngosayizi, imvamisa yokulinganisa ephezulu, futhi ithembeke.Iphezulu, inikeza i-spectrum eseduze nokusabela kwamehlo omuntu, ingasebenza ebumnyameni ukuqondisa ukukhanya kwelanga;ikwazi ukubona ukukhanya kwe-infrared, ngokunemba okuphezulu nokuvikeleka okuhle kakhulu.

I-proximity sensor (PS) inesihlungi esakhelwe ngaphakathi esingu-940nm sokuvikeleka kokukhanya kwe-ambient.Ngakho-ke, i-PS ingakwazi ukubona ukukhanya kwe-infrared okubonisiwe ngokunemba okuphezulu nokuvikeleka okuhle kakhulu;ingase futhi ibekwe ezingeni elihle, futhi i-current yayo emnyama incane., impendulo yokukhanya ephansi kanye nokuzwela okuphezulu;njengoba ukukhanya kwanda, okwamanje kushintsha ngokulandelana;ukuhlangabezana nezidingo zezimo ezihlukahlukene zezicelo.
