Electro-optical conversion thiab xyuas txoj kev ntawm LED teeb hlaws
Electro-optical hloov dua siab tshiab yog kev sib raug zoo nkhaus ntawm lub teeb tso zis hluav taws xob ntawm LED teeb hlaws thiab kev txhaj tshuaj tam sim no, uas yog, PI nkhaus. Vim tias nws yog hluav taws xob tshwm sim, cov kab ntau ntawm PI nkhaus yog qhov loj. Cov zis hluav taws xob kho qhov muag ntawm LED yog ib qho tseem ceeb ntawm LED, uas tau muab faib ua DC tso zis hluav taws xob Po thiab mem tes tso zis zog. Lub npe hu ua DC tso zis hluav taws xob yog hais txog lub zog kho qhov muag tawm los ntawm LED nyob rau hauv cov lus teev tseg rau pem hauv ntej DC ua haujlwm tam sim no. Thaum lub sij hawm xeem, muab lub teeb LED thiab lub receiver nyob rau hauv tib lub cassette, thiaj li hais tias lub teeb-emitting nto thiab qhov chaw tau txais yog sib npaug zos rau ib leeg thiab ze li sai tau. Kho qhov chaw tam sim no tas li kom qhov tam sim no rau pem hauv ntej IF yog tus nqi teev, thiab kev nyeem ntawv ntawm qhov taw qhia yog DC tso zis hluav taws xob kho qhov muag ntawm LED hauv kev sim. Lub thiaj li hu ua pulse output optical power yog hais txog lub zog kho qhov muag tawm los ntawm LED lub teeb-emitting nto nyob rau hauv lub voj voog pulse tam sim no ua haujlwm ntawm qhov teev amplitude, zaus thiab lub voj voog ua haujlwm.
Benwei Teeb pom kev zoo yog LED Tube, LED dej nyab teeb, LED Vaj Huam Sib Luag Teeb, LED High Bay, LED chaw tsim tshuaj paus nrog 12 xyoo kev paub. Yog tias koj xav yuav lub teeb zoo LED dej nyab lub teeb lossis muaj kev nkag siab ntau ntxiv ntawm daim ntawv thov ntawm LED dej nyab teeb, thov hu rau peb nug, peb lub vev xaib:
