"Piv nrog cov teeb pom kev zoo thiab cov teeb txuag hluav taws xob, cov yam ntxwv ntawm LED tuaj yeem cuam tshuam tag nrho nws cov nqi tsuas yog los ntawm kev txawj ntse." Nrog kev xav ntawm ntau tus kws tshaj lij, kab lus no tau maj mam nkag mus rau theem ntawm kev coj ua los ntawm lub tswv yim. Txij li thaum xyoo no, cov tuam ntxhab tau pib them nyiaj rau kev txawj ntse ntawm lawv cov khoom. Txawm hais tias kev txawj ntse tau muaj kev kub ntxhov hauv kev lag luam ua ntej, txij li cov teeb pom kev ntse nkag mus hauv Suav lag luam hauv xyoo 1990, nws tau nyob rau hauv kev txhim kho qeeb vim muaj kev txwv ntawm kev lag luam kev paub, kev lag luam ib puag ncig, khoom lag luam, nce qib thiab lwm yam. yam.

LED teeb pom kev zoo

Txawb xov tooj ncaj qha chaw taws teeb tswjLED teeb; Los ntawm kev teeb tsa kev teeb tsa thiab txawm tias lub cim xeeb muaj nuj nqi, lub teeb pom kev tuaj yeem hloov kho ntawm lub sijhawm sib txawv thiab cov xwm txheej, kom tsev neeg teeb pom kev zoo tuaj yeem hloov pauv ntawm qhov xav tau; Los ntawm cov teeb pom kev zoo sab hauv mus rau kev ntse tswj cov teeb pom kev sab nraum zoov… Raws li qhov txiaj ntsig zoo ntawm LED, lub teeb pom kev ntse yog suav tias yog qhov tseem ceeb ntawm kev loj hlob ntxiv kom muaj nuj nqis ntxiv ntawm semiconductor teeb pom kev zoo, thiab tau nyiam ntau lub lag luam tuaj koom. LED ntse teeb pom kev zoo tau dhau los ua ib qho tseem ceeb ntawm kev txhim kho cov lus qhia ntawm semiconductor teeb pom kev lag luam.

Piv txwv li, LED kub tswj thiab ntse txoj kev teeb pom kev zoo yog siv nyob rau hauv cov khoom tam sim no. Tab sisLED ntse teeb pom kev zooyuav ntau dua li ntawd, Silvia L Mioc ib zaug tau hais tias lub teeb pom kev ntse tau hloov pauv kev lag luam teeb pom kev zoo los ntawm cov cuab yeej siv peev rau hom kev pabcuam, ua kom cov khoom muaj nqis ntxiv. Tig lub neej yav tom ntej, qhov kev tawm tswv yim zoo tshaj plaws yog saib yuav ua li cas hloov lub teeb pom kev zoo rau hauv ib feem tseem ceeb ntawm Is Taws Nem thiab koom ua ke kev kho mob, lub zog, kev pabcuam, video, kev sib txuas lus thiab lwm yam.

Txawj ntseLED teeb pom kev zoosystem thiab sensing technology

Feem ntau, tib neeg feem ntau hais tias lub teeb pom kev ntse tswj qhov system hais txog lub teeb pom kev hauv tsev. "Sensor yog qhov txuas tseem ceeb kom paub lub teeb pom kev zoo". Hauv tsab ntawv tshaj tawm, nws tau sau tseg cov txheej txheem ntawm kev tswj lub teeb pom kev ntse, uas yog sensor + MCU + tswj kev ua tiav + LED = lub teeb pom kev ntse. Daim ntawv no tsuas yog piav qhia txog lub tswv yim, kev ua haujlwm thiab kev faib tawm ntawm cov sensors, nrog rau lawv daim ntawv thov thiab piv txwv hauv kev teeb pom kev ntse. Xib fwb Yan Chongguang faib cov sensors ua plaub pawg: pyroelectric infrared sensors, ultrasonic sensors, Hall sensors thiab photosensitive sensors.

Led xav tau kev koom tes ntawm kev txawj ntse system los rhuav tshem lub tswv yim teeb pom kev zoo

LED teeb ua rau peb lub ntiaj teb txuag hluav taws xob ntau dua. Nyob rau tib lub sijhawm, kev sib txuas ntawm LED teeb kev sib txuas lus thiab kev tswj hom yuav yooj yim dua thiab ntsuab. LED teeb tuaj yeem xa cov teeb liab network thiab tswj cov teeb liab los ntawm lub teeb, xa cov teeb liab modulated, thiab ua kom tiav kev xa cov ntaub ntawv thiab cov lus qhia. Ntxiv nrog rau kev sib txuas ntawm lub network, LED teeb tseem tuaj yeem ua tus thawj coj ntawm ntau yam khoom siv hauv tsev. Tshwj xeeb, lub tsev teeb pom kev zoo yog qhov tseem ceeb tshaj plaws ntawm daim ntawv thov kev lag luam; Nws hais tias kev siv hluav taws xob ntawm cov tsev yog siab heev. Qee lub tebchaws nyob sab Europe thiab Asmeskas tau tsim cov teeb pom kev zoo rau lub hom phiaj no. Kev siv lub teeb pom kev zoo tuaj yeem cuam tshuam nws qhov zoo ntawm kev txuag hluav taws xob thiab kev tswj hwm.
