Iyo ambient light sensorinonyanya kuumbwa ne optical components.Photosensitive components dzakagadzirwa nekukurumidza, akawanda marudzi, uye anoshandiswa zvakanyanya.Iyo yemamiriro ekunze mwenje sensor inogona kuona yakatenderedza mwenje mamiriro uye kuzivisa iyo yekugadzirisa chip kuti igadzirise otomatiki backlight yemonitor kuderedza kushandiswa kwesimba kwechigadzirwa.Kune rimwe divi, ambient light sensor inobatsira chiratidziro chine mufananidzo wakapfava.Kana kupenya kwenzvimbo kwakakwira, iyo liquid crystal inoratidzira ichishandisa ambient light sensor inongogadzirisa kupenya kwakanyanya.Kana nzvimbo yekunze yakasviba, chiratidziro chichagadziriswa kuita kupenya kwakaderera.
Chirenga chinhambwe chiri padyo ne sensor chip -WH APS 4530A imhando yechiedza kudhijitari inoshandura.Iyo inosanganisa epamberi emwenje mwenje sensors, advanced sensors uye yakakwirira-inoshanda infrared LED mwenje.Sefa inovakwa -in sefa yekudzvanya infrared, uye inopa spectrum padyo nemaitiro emeso evanhu.ALS inogona kushanda pasi perima kusvika kuchiedza chezuva, uye iyo yakasarudzwa yekuona mhando inenge 40dB.Dual -channel output (ziso remunhu uye rakajeka), kuitira kuti ALS ive nechiyero chakanaka chechiedza pasi pemamiriro akasiyana echiedza.Iyo 940nm sefa inovakwa -in sensor (PS) yechiedza chezvakatipoteredza.Naizvozvo, PS inogona kuona reflex infrared mwenje, ine yakanyanya kurongeka uye yakanakisa kuramba.Iyo WH4530A ine programmable kukanganisa basa, uye ine pachikumbaridzo-yakavakirwa lag yeALS nePS.
Environmental light sensors ane diki dema ikozvino, yakaderera-inovhenekera mhinduro, yakakwirira senitivity, uye mutsara shanduko nekupenya kwechiedza chezvino;yakavakwa -in dual -sensitive element, automatic attenuation near infrared, spectral response pedyo nemeso evanhu basa rekuita curve (dema: ziso remunhu rinopindura curve curve , Bhuruu: Optical resistance response curve, green: ambient light response curve);Imwe kufunga kweimwe kufunga pakusarudza yakakodzera mwenje sensor ndeyekusarudza sensor ine yakanakira spectrum mhinduro.Yakajairwa PIN Photosami diode kana optical kuramba (passive kana inoshanda) pachayo ine yakakura kwazvo yekutarisa mhinduro renji, kusanganisira IR ranzi uye kunyange UV mwaranzi.
