Cov khoom siv hauv semiconductor uas siv hauv lub raj xa hluav taws xob feem ntau yog gallium arsenide (GaAs), gallium arsenide (GaAlAs), thiab lwm yam., Thiab tau ntim rau hauv pob tshab los yog xim dub, xim dub. Tam sim no, daim ntawv thov infrared emission tube yog qhov teeb meem ntawm ntau yam kev teeb tsa photoelectric, uas yog siv rau hauv chaw taws teeb tswj, tswb thiab kev sib txuas lus wireless, xws li tsaus nti red translucent kheej peb pom nyob rau pem hauv ntej kawg ntawm cov khoom siv kis kab mob xws li TV chaw taws teeb tswj. Tus ntaus ntawv yog ib qho hluav taws xob hluav taws xob hluav taws xob hluav taws xob.
Thaum siv, lub qhov hluav taws xob ntawm qhov hluav taws xob ntawm lub taub hau yuav tsum tau ceev faj, thiab sab nrauv yuav tsum tsis txhob muab pov tseg thiab puas ntsoog. Txwv tsis pub, lub teeb ntaiv ntawm lub teeb ci tuaj yeem yuav pom los yog tawg, uas cuam tshuam ncaj qha rau kev siv cov nyhuv. Qhov no kuj yog peb txoj haujlwm thiab siv. .
Cov teeb meem hluav taws xob hauv hluav taws xob (LED infrared emission tube) yuav tsum tau siv nrog cov taws teeb taws taub hau taub hau. Vim li no, thaum xaiv hom, them nyiaj tshwj xeeb seb puas muaj qhov tsis muaj teeb meem ntawm qhov teeb meem ntawm lub teeb ci ntsa iab uas lawv tau ua kom sib haum xeeb (dua li tau txiav txim los ntawm tib lub chaw tsim hluav taws xob), txwv tsis pub lub siab txais tos.
Kev ua haujlwm ntawm infrared ua hauj lwm
Nws kuj muaj ntau ntau hom LED infrared receivers. Nws muaj feem ntau peb lub pins, nrog rau lub hwj huam fais fab, lub hauv av thiab cov zis teeb tawm. Feem ntau, cov khw muab cov khoom siv hluav taws xob sib txuas ua ke rau hauv ib qho kev tivthaiv rau kev sib txuas ua ke. Lub voj voog xws li cov infrared receivers, amplifiers, limiters, bandpass lim, kev sib txuas ntawm circuits thiab sib piv. LED infrared txais taub hau tau lub teeb liab infrared, thiab mam li xa lub teeb liab mus rau lub zog thiab tus limiter. Lub limiter tso cai rau lub plhaub taum plawv ntawm qhov chaw siab (vim tias qhov sib txawv ntawm qhov teeb meem ntawm infrared transmitter xa tub tsis meej), AC lub teeb liab ces nkag mus rau lub hnab lim (dhau ntawm 30khz mus rau 60khz), ces nkag mus rau tus piv los ntawm txoj kev sib cog lus ntawm kev sib txuas lus thiab cov kev sib tos ua ke, thiab lub teeb liab tawm ntawm lub tso tawm cov zis yog txo kom mus rau lub transmitter.
Cov chaw taws teeb tswj hluav taws xob hauv cov cuab yeej hluav taws xob yog cov niaj hnub siv daim duab hluav taws xob hluav taws xob hluav taws xob thiab lub taub hau. Nws qhov zoo yog qhov zoo los cuam tshuam, yooj yim thiab yooj yim rau kev siv hluav taws xob, kev siv hluav taws xob tsawg tsawg thiab pheej yig, thiab tam sim no yuav luag tag nrho cov khoom siv hluav taws xob hauv tsev uas siv cov cuab yeej no.
