IR LED yog dab tsi?
IR LED yog infrared teeb pom kev zoo emitting diode.
Dab tsi yog qhov txawv ntawm LED thiab IR LED?
LED yog luv luv rau lub teeb emitting diode, txhais tau tias lub diode yog nrog teeb pom kev zoo emitting fuction thaum hluav taws xob dhau.
IR LED yog lub teeb emitting diode, tab sis lub teeb hre nws' lub teeb infrared uas tsis pom.
IR LED siv rau dab tsi?
Peb tuaj yeem pom cov IR LED siv zoo li cov chaw taws teeb tswj, xa cov teeb liab programmed rau TV teeb.
Los yog ntawm CCTV koob yees duab thaum hmo ntuj illumination, Thaum muaj' tsis pom lub teeb nyob rau hauv qhov tsaus ntuj, IR LED muab
hmo ntuj pom kev rau CCTV.
Dab tsi yog qhov txawv ntawm 850nm IR LED thiab 940nm IR LED?
Pom pom wavelength yog kwv yees li ntawm 400nm (ze rau ntshav thiab xiav) txog 700nm (ze rau liab)
Tshaj 700nm ib txwm peb tuaj yeem hais nws' s infrared lossis luv rau IR.
850nm IR LED yog zoo li tus qauv wavelength rau CCTV, nws muab illumination zoo nyob rau hauv qhov tsaus ntuj nti.
Txawm li cas los xij, txij li nws' lub wavelength tseem nyob ze rau tib neeg' qhov pom ntau yam, peb tseem tuaj yeem pom me ntsis liab ci thaum
saib ntawm IR LEDs.
940nm LED nws' ntau deb ntawm tib neeg' qhov pom ntau yam piv rau 850nm IR LED, yog li nws tuaj yeem pom tag nrho rau
tib neeg ob lub qhov muag thiab nws' zoo rau daim ntawv thov zoo li npog lub koob yees duab. Tsis tas li ntawd, nws tuaj yeem yog qhov kev xaiv zoo rau kev tswj chaw taws teeb
daim ntawv thov. Txij li nws' nyob deb ntawm qhov pom lub teeb, nws tuaj yeem zam lub suab nrov thaum ua ke nrog 940nmIR receiver.
