Tshuab ir coj mus rau qhov teeb meem tshiab
Infrared lub raj (Ir LED) kuj tseem hu infrared emitting emitting diode, uas belongs rau qeb ntawm LED diodes. Nws yog lub teeb ci ntsa iab uas tuaj yeem hloov kho hluav taws xob hluav taws xob rau hauv cov teeb pom kev zoo nyob rau hauv ze-infrared teeb (pom lub teeb pom kev zoo (lub teeb pom kev) thiab ci ntsa iab rau nws. Nws yog tsuas yog siv nyob rau hauv ntau lub tshuab luam yeeb, kov cov ntxaij vab tshaus thiab chaw taws teeb tswj kev voj voog. Tus qauv thiab txoj ntsiab cai ntawm infrared raj yog zoo li cov ntawm lub teeb dived emitting, tab sis cov semiconductor ...
