Ngokuphucuka kwemigangatho yokuphila yabantu, iintsapho ezininzi ziyaqala ukufakelwaukukhanya okukrelekreleiinkqubo ngexesha lokuhombisa ukubonelela ngeenkonzo ezikumgangatho ophezulu nezikhululekileyo. Iinkqubo zokukhanyisa ikhaya ezikrelekrele zinokuphucula umgangatho weendawo zokukhanyisa zokuhlala kwaye zijolise ngokupheleleyo ebantwini. Ukuqwalasela ngokupheleleyo iziphumo ezibonakalayo zabantu, kunye nokuqwalasela "ingxaki yokuphazamiseka kwexesha" ebangelwa kukuncipha kokukhanya kwexesha, ukudala indawo yokuhlala eyenzelwe wena, yobugcisa, ekhululekileyo nentle, kodwa inkqubo yokukhanyisa ibisoloko iyinto ebalulekileyo yokusetyenziswa kwamandla okwangoku inengxaki yokuchithakala okukhulu, ngoko ke uphuhliso lokukhanyisa okukrelekrele lubaluleke kakhulu.

Iiteknoloji ezine zolawuloukukhanya okukrelekrele:

Ukukhanya okulawulwa kude:Izixhobo zokukhanyisa zilawulwa ngemiqondiso yerediyo. Ungasebenzisa iklayenti yefowuni ephathwayo ukulawula iswitshi kude, kwaye ezinye zixhotyiswe ngeesokhethi zokutshintsha kunye neetransmitter xa uzithenga.

Ukuqonda nge-infrared:Ngokubamba imisebe ye-infrared yee-wavelengths ezithile ukulawula ukukhanya nokucima izibane, ukukhanya okulibazisekileyo kunokufezekisa isiphumo "sezibane ezikhanyayo xa abantu befika nokucima xa abantu bemka".

Izibane ezidibeneyo:Kule mihla, ukukhanya okudibeneyo okuqulunqwe yimithombo emininzi yokukhanya kuye kwakhula kakhulu, kwaye zombini izigcawu kunye nokukhanya kombala zinokudityaniswa ngokukhululekileyo.

Ukukhanya okuchukumisayo:Utshintsho kumthamo wezibane lubangelwa kukuchukumisa iminwe ukuze kulawulwe izibane. Ubushushu kunye neempawu zokuthintela amanzi zifanelekile kwigumbi lokuhlambela, iikhitshi kunye nezinye iindawo.

Imisebenzi emithandathu ephambili yeukukhanya okukrelekrele:

1. Umsebenzi wokulawula ixesha ukuvumela ukuba ulungise ngokukhululekileyo ixesha lesibane sokukhanyisa, njengoko ukhetha kwaye usisebenzisa, kwaye siya kukunceda ngalo lonke ixesha.

2. Ulawulo oluphakathi kunye nomsebenzi weendawo ezininzi: Isiphelo sendlela nakweyiphi na indawo sinokulawula izibane kwiindawo ezahlukeneyo; okanye isiphelo sendlela kwiindawo ezahlukeneyo sinokulawula ukukhanya okufanayo.

3. Imisebenzi yokukhanyisa ngokupheleleyo, ukucima ngokupheleleyo kunye nememori. Izibane zenkqubo yonke yokukhanyisa zinokuvulwa ngokupheleleyo kwaye zicinywe ngokucofa kanye. Akukho mfuneko yokucinezela amaqhosha ngamanye ukuze ucime okanye uvule izibane, ukunciphisa ingxaki engeyomfuneko.

4. Useto lwe-scene lubeka imo esisigxina, kwaye lunokulawulwa ngokucofa kube kanye emva kokwenza iprogram kube kanye. Okanye khetha useto lwasimahla, lunike imisebenzi engakumbi ngokweemfuno zakho, kwaye ulawule ikhaya lakho ngeengcinga zakho.

5. Umsebenzi wokuqalisa ngokuthambileyo: Xa ukukhanya kuvuliwe, ukukhanya kuyatshintsha kancinci ukusuka ebumnyameni ukuya ekukhanyeni. Xa ukukhanya kucinyiwe, ukukhanya kuyatshintsha kancinci ukusuka ekukhanyeni ukuya ebumnyameni. Oku kuthintela utshintsho olukhawulezileyo ekukhanyeni ukuba lungacaphukisi iliso lomntu, kubonelela nge-buffer yeliso lomntu kwaye kukhusele amehlo. Kwakhona kuthintela impembelelo yotshintsho olukhawulezileyo kumbane ophezulu kunye nobushushu obuphezulu kwi-filament, kukhusela ibhalbhu, kwaye kwandisa ubomi benkonzo. Ingakhanyisa ukukhanya kancinci kancinci xa abantu besondela kuyo, kwaye ifiphale kancinci njengoko umntu ehamba, okonga umbane ngempumelelo.

6. Umsebenzi wokulungisa ukukhanya kwezibane Nokuba wenza yiphi na indawo, ungayilungisa imo yesiganeko kunye nokukhanya okufunayo ngokwesibhedlele sakho. Ukukhanya okuhlukeneyo kokukhanya kunokulungiswa ukuze kwamkelwe iindwendwe, amatheko, iimuvi, kunye nokufunda. Ukukhanya okuncinci nokumnyama kukunceda ucinge, ngelixa ukukhanya okungaphezulu nokukhanyayo kwenza umoya ube nomdla ngakumbi. Le misebenzi ilula kakhulu. Ungacinezela kwaye ubambe iswitshi yendawo ukuze ukhanyise kwaye unciphise ukukhanya, okanye ungasebenzisa isilawuli esiphakathi okanye ulawulo olukude ukuze ulungise ukukhanya kokukhanya ngokucinezela iqhosha kube kanye.

Izinzwa zokukhanya ezikufutshane zenziwe ikakhulu zizinto ezibonisa ukukhanya. Izinto ezibonisa ukukhanya ziyakhula ngokukhawuleza, zineentlobo ngeentlobo kunye nezicelo ezibanzi. Inzwa yokukhanya ekufutshane inokuyiqonda imeko yokukhanya ejikelezileyo kwaye ixelele itshiphu yokucubungula ukuba ilungise ngokuzenzekelayo ukukhanya kwesibane esingasemva ukuze inciphise ukusetyenziswa kwamandla kwemveliso. Umzekelo, kwizicelo zeselula ezifana neefowuni eziphathwayo, iincwadana, kunye neethebhulethi, isibonisi sisebenzisa ukuya kuthi ga kwi-30% yamandla ebhetri iyonke. Ukusetyenziswa kwezinzwa zokukhanya ezikufutshane kunokwandisa ixesha lokusebenza kwebhetri. Kwelinye icala, isinzwa sokukhanya esikufutshane sinceda isibonisi ukuba sinikeze umfanekiso othambileyo. Xa ukukhanya okukufutshane kuphezulu, isibonisi se-LCD esisebenzisa isinzwa sokukhanya esikufutshane siya kuzilungisa ngokuzenzekelayo ukukhanya okuphezulu. Xa imeko yangaphandle imnyama, isibonisi siya kulungiswa ukukhanya okuphantsi. Inzwa yokukhanya ekufutshane ifuna ifilimu yokusika i-infrared kwitshiphu, okanye ifilimu yokusika i-infrared enepatheni efakwe ngqo kwi-silicon wafer.

I-WH4530A eyasungulwa yiTaiwan Wanghong sisivamvo somgama ophantsi esidibanisa isivamvo sokukhanya esingqongileyo (ALS), isivamvo sokusondela (PS) kunye nesibane se-infrared LED esisebenza kakuhle kakhulu sibe yinto enye; uluhlu lungalinganiswa ukusuka kwi-0 ukuya kwi-100cm; Isebenzisa i-interface ye-I2C, inokufezekisa imisebenzi efana novakalelo oluphezulu kakhulu, uluhlu oluchanekileyo kunye noluhlu olubanzi lokufumanisa.

Le chip isombulula iingxaki zezixhobo zemveli zokusondela kwi-infrared, ultrasonic kunye nerediyo ezifana novakalelo oluphantsi, isantya sokuphendula kancinci, ukuthembeka okuphantsi, kunye nokusetyenziswa kwamandla aphezulu. Isebenzisa uyilo lwe-optical olukumgangatho ophezulu, yenza i-proximity sensor ibe ncinci ngobukhulu, i-frequency ephezulu yokulinganisa, kwaye ithembeke. Iphezulu, inika i-spectrum esondele kwimpendulo yamehlo omntu, inokusebenza ebumnyameni ukuya elangeni ngqo; inokubona ukukhanya kwe-infrared okubonisiweyo, ngokuchaneka okuphezulu kunye nokuzikhusela okuhle kakhulu.

I-proximity sensor (PS) inesihluzo se-940nm esakhelwe ngaphakathi sokukhusela ukukhanya okungqongileyo. Ke ngoko, i-PS inokubhaqa ukukhanya kwe-infrared okubonakalisiweyo ngocoselelo oluphezulu kunye nokukhusela okugqwesileyo; isenokumiselwa kwinqanaba elincinci, kwaye umsinga wayo omnyama umncinci. , impendulo yokukhanya okuphantsi kunye novakalelo oluphezulu; njengoko ukukhanya kusanda, umsinga utshintsha ngokuthe ngqo; ukuhlangabezana neemfuno zeemeko ezahlukeneyo zokusetyenziswa.
