Dareemiyaha LED-ka Cusub ee Iftiinka Iftiinka Wacan

Nidaamyada dareenka garaadka

Iyada oo ku saleysan mabda'a shaqada ee dareenka shucaaca infrared jirka bini'aadamka, naqshadeynta gaarka ah iyo shaqada iftiinka dareenka LED ayaa soo jiidatay dareen badan tan iyo markii la bilaabay.Iftiinka dareemayaasha LED wuxuu isticmaalaa shucaaca infrared-kuleylka ee ka soo baxa jidhka bini'aadamka, iyo iyada oo loo marayo saameynta isku-dhafka ah ee dareenka jirka bini'aadamka ee qaybta madaxa laambada iyo filter Fresnel, waxay gartaa dareenka iyo ka jawaabista hawlaha jidhka bini'aadamka.

Iftiinka dareemayaasha LED wuxuu leeyahay saddex qaybood oo gudaha ah, kuwaas oo kala ah moduleka dareenka kulaylka, moduleka beddelka wakhtiga dib-u-dhaca iyo module-dareenka iftiinka.Qaybta dareemida kulaylka ayaa mas'uul ka ah ogaanshaha fallaadhaha infrared kulaylka ah ee jidhka bini'aadamka, moduleka beddelka wakhtiga dib u dhaca ayaa mas'uul ka ah xakamaynta tirada wakhtiga iftiinka iyo daminta, iyo module-dareenka iftiinka ayaa loo isticmaalaa si loo ogaado xoogga iftiinka deegaanka.

Bey'ad iftiin xoog leh, moduleka dareenka iftiinka ayaa xiri doona dhammaan xaaladda iftiinka, xitaa haddii qof ku dhex gudbo inta u dhexeysa iftiinka dareenka LED, ma kicin doono iftiinka.Xaaladda iftiinka hooseeya, moduleka dareenka iftiinka wuxuu gelin doonaa iftiinka dareenka LED-ka ee heeganka wuxuuna dhaqaajin doonaa moduleka dareenka kulaylka infrared ee bini'aadamka iyadoo loo eegayo qiimaha waxtarka iftiinka ee la ogaaday.

Marka qaybta dareemada kulaylka infrared ee bini'aadamka ay dareemaan in qof firfircoon yahay inta u dhaxaysa, waxay dhalin doontaa calaamad koronto, taas oo kicin doonta moduleka beddelka wakhtiga dib u dhigista si uu u shido, iyo tusaha iftiinka LED-ka ayaa la kicin karaa si ay u iftiimiyaan.Habka daahitaanka wakhtiga daahitaanka wuxuu leeyahay waqti go'an, badanaa 60 ilbiriqsi gudahood.Haddii jidhka bini'aadamku ku sii socdo in uu ku dhex socdo qiyaasta dareenka, iftiinka dareenka LED wuu sii jirayaa.Marka uu jidhka bini'aadmiga ka baxo, qaybta dareemada jidhka bini'aadamku ma awoodo inay ogaato fallaadhaha infrared ee jidhka bini'aadamka, mana awoodo inay u soo dirto signalka moduleka beddelka wakhtiga, iftiinka dareenka LED wuxuu si toos ah u dami doonaa qiyaastii 60. ilbiriqsiWaqtigan xaadirka ah, cutub kastaa wuxuu geli doonaa gobolka heeganka, isagoo diyaar u ah wareegga shaqada ee xiga.

Hawlaha

Shaqada ugu dareen badan ee iftiinka dareemayaasha LED-ka waa in si caqli-gal ah loo hagaajiyo iftiinka iyadoo loo eegayo iftiinka iftiinka iftiinka iyo xaaladda dhaqdhaqaaqa aadanaha.Marka iftiinka deegaanku uu xoog badan yahay, iftiinka dareemayaasha LED ma iftiimi doono si uu tamarta u badbaadiyo.Marka iftiinku hooseeyo, iftiinka dareeraha LED-ku wuxuu geli doonaa heerka heeganka ah, marka jidhka bini'aadamku galo qiyaasta dareenka, iftiinku si toos ah ayuu u shidmi doonaa.Haddii jidhka bini'aadamku sii wado firfircoonida, iftiinku wuu shid doonaa ilaa uu si toos ah u damiyo qiyaastii 60 ilbiriqsi ka dib marka jidhka bini'aadamku baxo

Daahfurka nalalka dareemayaasha LED ma aha oo kaliya inay bixiyaan xalal iftiin caqli-gal ah, laakiin sidoo kale waxay si wax ku ool ah u yareeyaan isticmaalka tamarta.Waxaa si weyn loogu isticmaalaa meelaha dadweynaha, waddooyinka, baarkinnada baabuurta iyo meelaha kale, taas oo aan hagaajinaynin saamaynta iftiinka, laakiin sidoo kale waxay dadka u keentaa khibrad nololeed oo ku habboon oo raaxo leh.Horumarka joogtada ah ee sayniska iyo tignoolajiyada, rajada codsiga ee iftiinka dareemayaasha LED wuxuu noqon doonaa mid aad u ballaaran, taasoo keenaysa ku habboonaansho iyo khibrad caqli badan nolosheenna.
