Qhia Koj Yuav Paub Qhov txawv Infrared Transmitted Tubes thiab Infrared Txais

Lub tshuab tso tawm ntawm infrared LED teeb hlaws thiab lub raj tau txais ntawm infrared LED teeb hlaws yog hu ua infrared LED teeb hlaws. Cov duab ntawm lub teeb infrared LED hlaws dai zoo ib yam li qhov zoo tib yam puag ncig LED teeb hlaws. Thaum koj thawj zaug hu rau infrared LED teeb hlaws dai, nws yog qhov nyuaj rau kev paub qhov txawv ntawm cov emitter ntawm infrared LED teeb hlaws thiab lub raj tau txais ntawm infrared LED teeb hlaws. R & D cov neeg ua haujlwm tau hais tias txoj kev txiav txim siab tuaj yeem siv los ua qhov txawv: siv multimeter los ntsuas kev txheeb xyuas los ntsuas qhov polar resistance ntawm infrared LED teeb hlaws nrog multimeter los txiav txim seb nws puas yog infrared LED teeb hlaws. Txiav txim siab 1: Thaum lub sij hawm infrared LED teeb hlaws dai, qhov ntsuas qhov ntsuas tau txo qis nyob rau hauv qhov xwm txheej ntawm lub teeb irradiation, qhov kev tiv thaiv rau pem hauv ntej ntawm lub raj xa tawm me me, qhov rov qab tsis kam yog qhov loj, thiab lub rooj xim dub yog qhov zoo (ntev pins), Qhov kev tiv thaiv yog txuas nrog lub resistor, thiab tus resistor Me (1K —20K) yog lub raj xa hluav taws xob ntawm infrared LED teeb hlaws. Qhov loj thiab rov qab tsis kam yog lub raj tau txais ntawm infrared LED teeb hlaws. Kev Txiav Txim 2: Thaum lub rooj dub txuas nrog tus ncej tsis zoo yog qhov loj tsis kam ntawm infrared LED teeb hlaws dai. Thaum qhov kev tiv thaiv me me thiab peb lub hom phiaj ntsuas ntsuas qhov ntsuas hloov nrog lub teeb thiab tsis muaj zog ntawm lub teeb, lub pointer yog viav vias lub infrared LED teeb hlaws txais lub raj. Fais fab-powered xeem txiav txim ntawm infrared LED teeb hlaws Peb tuaj yeem siv thawj lub teeb ci LED hlaws thiab —Qhov kev tiv thaiv no thiab kev sim infrared LED teeb hlaws dai txuas nrog hauv series, thiab LED teeb hlaws yog siv los tso saib cov xwm txheej ua haujlwm ntawm lub raj infrared raj. Siv cov chaw taws teeb tswj (DVD cov chaw taws teeb tswj, thiab lwm yam) txhawm rau nias tus yuam sij ntawm cov chaw taws teeb tswj mus rau lub raj ntsuas. Thaum lub teeb ci ci, lub raj yog lub raj tau txais ntawm infrared LED teeb hlaws. Yog tias nws tsis ci, nws yog lub raj xa hluav taws xob ntawm infrared LED teeb hlaws. Ntsuas qhov ua hauj lwm tam sim no ntawm kev ua hauj lwm voltage ntawm infrared LED teeb hlaws ntawm lub transmitter circuit, uas tuaj yeem txiav txim siab seb nws ua haujlwm li cas. Thaum ntsuas qhov ua haujlwm voltage ntawm ob qho kawg ntawm lub raj, nws feem ntau yog xoom nyob rau hauv zoo li qub (uas yog, thaum lub pob tsis nias), thiab qhov dynamic (thaum koj nias ib lub pob) yuav dhia mus rau qhov nqi hluav taws xob me me, vim tias lub encoding ntawm cov chaw taws teeb tswj system yuav yog Cov qauv ntawm txoj kev, cov qauv ntawm cov tsav Circuit Court thiab qhov voltage ntawm kev ua hauj lwm fais fab mov, tus nqi voltage feem ntau yog nyob nruab nrab ntawm 0.1 thiab 0.85V. Yog tias tus nqi tsis dhau los yog qhov sib txawv ntau dhau lawm, koj tuaj yeem txiav txim siab tias lub teeb infrared LED hlaws hlaws ua haujlwm txawv txav. Lub infrared LED teeb hlaws yuav tsum tau khaws cia kom huv si thiab zoo, tshwj xeeb tshaj yog cov kab sib txuas ntawm qhov kawg ntawm lub hauv ntej kawg tsis tuaj yeem muaj cov pa phem xws li av, tsis muaj kev sib txhuam. Qhov tshwm sim ntawm kev tawg ncaj qha cuam tshuam rau kev sib kis ntawm lub teeb infrared. Lub teeb tuaj yeem txo qhov rhiab heev ntawm cov chaw taws teeb tswj thiab txo qhov kev tswj qhov deb. Nyob rau hauv tus txheej txheem ntawm kev ua hauj lwm nyob rau hauv tus txheej txheem ntawm infrared LED teeb hlaws dai, lawv tsis yuav tsum tsis txhob tshaj qhov txwv. Yog li ntawd, thaum hloov cov qauv xaiv, them sai sai rau cov qauv thiab cov yam ntxwv ntawm tus thawj raj. Tsis tas li ntawd, koj yuav tsum tsis txhob hloov qhov tam sim no ntawm infrared LED teeb hlaws ntawm lub siab nyiam. Vim hais tias qhov ntau ntawm infrared lub teeb wavelengths yog dav heev, infrared LED teeb hlaws yuav tsum tau ua ke nrog infrared diode, txwv tsis pub nws yuav cuam tshuam qhov rhiab heev ntawm cov chaw taws teeb tswj thiab txawm ua rau tsis muaj kev tswj hwm. Yog li ntawd, thaum hloov hom xaiv, nco ntsoov them sai sai rau lub wavelength tsis tau ntawm lub teeb infrared teeb liab uas radiated lub teeb infrared. Infrared LED teeb hlaws muaj qhov hardness tsawg, thiab lawv qhov kub thiab txias ua haujlwm tsis zoo. Txhawm rau kom tsis txhob muaj kev puas tsuaj, qhov taw tes solder yuav tsum nyob deb ntawm lub hauv paus ntawm cov pins, thiab qhov vuam kub yuav tsum tsis txhob siab dhau. Lub sijhawm vuam yuav tsum tsis txhob ntev dhau. Nws yog qhov zoo tshaj los siv nws. Hlau gardenia pinch lub hauv paus ntawm pins los pab kom sov dissipation. Kev kho ntawm tus pinwing hloov yuav tsum ua kom tiav ua ntej vuam, thiab lub raj thiab tus pin yuav tsum tsis txhob ntxhov siab thaum lub vuam. Hais txog kev paub txog infrared LED teeb hlaws, kuv yuav piav qhia hnub no. Tom qab xav txog ntau cov ntaub ntawv LED teeb hlaws, thov ua tib zoo saib rau Xiaobian. Yog tias koj xav tau LED teeb hlaws, koj tuaj yeem tiv tauj peb cov neeg ua haujlwm pabcuam cov neeg siv khoom!
