Cov yam ntxwv thiab kev siv ntawm Infrared LED hlaws

Infrared tej thaj chaw deb tswj tau siv dav hauv TV, suab tshuab, thiab ntau yam khoom siv hauv tsev. Kev tswj qhov deb ntawm cov chaw taws teeb tswj feem ntau tuaj yeem ncav cuag 6-8 meters, ua rau nws yooj yim heev rau siv. Vim yog kev siv loj ntawm infrared chaw taws teeb tswj, nws cov infrared kis tau tus mob thiab txais tos circuits yog nruab nrog tag nrho cov kev txhawb nqa Cheebtsam, uas tsis tsuas yog tus nqi-zoo tab sis kuj txhim khu kev qha, thiab lub Circuit Court yog heev yooj yim. Cov neeg nyiam siv hluav taws xob tuaj yeem yooj yim sib sau ua ke cov chaw taws teeb tswj rau ntau lub hom phiaj siv cov khoom siv no, uas tsis yog tsuas yog siv tau tab sis kuj ua rau lawv txaus siab rau ntau lawm.
Cov yam ntxwv ntawm infrared LED hlaws dai yog tias lub teeb infrared tsis pom thiab tsis tuaj yeem pom los ntawm tib neeg lub qhov muag. Feem ntau siv infrared LED hlaws dai muaj qhov zoo ib yam li cov hlaws LED zoo tib yam. Txo lub voj voog ua haujlwm mem tes kuj tseem tuaj yeem ua rau kom qhov emission nrug ntawm qis zog infrared teeb-emitting diodes. Lub teeb pom kev zoo ntawm lub teeb-emitting diodes tau muab faib ua peb pawg ntawm lub zog: qis zog (1mW ~ 10mW), lub zog nruab nrab (20mW ~ 50mW), thiab lub zog siab (50mW ~ 100mW lossis ntau dua). Thaum siv infrared lub teeb-emitting diodes nrog lub zog sib txawv, cov khoom siv hluav taws xob sib txuas yuav tsum tau teeb tsa. Txhawm rau tsim cov teeb pom kev zoo los ntawm infrared lub teeb-emitting diodes, tsuas yog siv cov mem tes voltage ntawm qee zaus rau lub raj tsav tsheb.
Thaum siv infrared lub teeb-emitting diodes kom emit infrared hluav taws xob los tswj cov cuab yeej tswj, muaj cov khoom sib xws infrared photoelectric hloov dua siab tshiab hauv cov khoom tswj, xws li infrared txais diodes, phototransistors, thiab lwm yam.
Muaj ob txoj hauv kev tawm thiab tau txais hluav taws xob infrared, ib qho yog hluav taws xob ncaj qha thiab lwm qhov yog kev xav. Hom ncaj qha yog hais txog qhov chaw ntawm lub teeb-emitting raj thiab lub raj tau txais ntawm qhov kawg ntawm cov khoom emitting thiab tswj, nrog rau qee qhov kev ncua deb ntawm; Reflective yog hais txog qhov xwm txheej uas lub teeb-emitting raj thiab lub raj txais tau muab tso rau ntawm ib sab, thiab lub raj tau txais ib txwm tsis muaj lub teeb. Nws tsuas yog ua haujlwm thaum lub teeb infrared emission los ntawm lub teeb-emitting raj ntsib lub reflector, thiab lub txais lub raj tau txais lub reflected infrared teeb.
