Yuav ua li cas paub qhov txawv Patch LED Positive thiab Negative Ncej?

Ua ntej, tsis muaj teeb meem dab tsi xim yog qhov zoo thiab qhov tsis zoo yog kho. Qhov zoo thiab qhov tsis zoo ntawm thaj LED: Ua tib zoo saib ntawm sab xub ntiag ntawm thaj LED. Muaj ib lub kaum sab xis nyob rau hauv ib lub square lossis ib lub duab plaub. Muaj lub kaum sab xis ntawm lub kaum sab xis, thiab sab nraud yog qhov tsis zoo electrode. Qhov zoo thiab qhov tsis zoo ntawm LED teeb hlaws dai: Ua tib zoo saib ntawm lub hauv ntej ntawm LED teeb hlaws. Ntawm ob qhov kawg ntawm LED teeb hlaws, muaj lub kaum me me ntawm qhov kawg ntawm LED teeb hlaws, thiab qhov kawg ntawm lub kaum sab xis yog qhov zoo thiab lwm qhov kawg yog qhov tsis zoo electrode. LED straw kaus mom teeb yog qhov txawv ntawm qhov zoo thiab tsis zoo electrodes ntawm LED straw kaus mom: LED tshiab tsis tau txiav, ntev taw yog qhov zoo, lwm qhov kawg yog qhov tsis zoo electrode, txhua qhov chaw tsim khoom yuav txawv. Yog tias nws tau ntim los ntawm thaj 2512 Los yog ib qho ntawm cov xim yog qhov tsis zoo electrode, hauv qab yog qhia los ntawm daim duab peb sab, lub taub hau loj yog qhov zoo, lub taub hau me yog qhov tsis zoo electrode, thiab cov pob loj yog qhov zoo thiab qhov tsis zoo. Qhov thib ob, koj tuaj yeem siv lub multimeter Ohm saib. Rau dial-style multimeter, kho rau “Om X1 ”Thaum lub diode ci ntsa iab, lub moos liab txuas nrog qhov kawg ntawm SMDLED, thiab lub moos dub txuas nrog qhov tsis zoo kawg ntawm SMDLED. Qhov thib peb, vim hais tias LED qhib txwv yog li 1.5-1.8V. Nws yog qhov ua tau tias qhov hluav taws xob muab los ntawm digital multimeter tsis tuaj yeem pib nws. Yog li saib lub cim. Lub thaj emitting dilate (SMDLED) muaj ib tug tsis zoo ncej nrog ntsuab dots thiab kuj zoo. LED lub zog-txuag lub teeb pom kev zoo thiab tsis zoo ntawm txoj kev paub: Txoj kev siv ntau tshaj plaws yog txoj kev tshawb nrhiav multimeter. Thaum siv multimeter los ntsuas lub teeb-emitting diode, koj yuav tsum siv nws “R ×L0K ”cov ntaub ntawv. Cov yeeb nkab siab ntawm lub siab phem diode yog hais txog 3V, thiab lub universal saib nyob rau hauv “R ×Xauv ”Thiab thaum qhov kev tawm tsam hauv qab no raug thaiv. Lub roj teeb hauv lub rooj tsuas yog 1.5V. Hauv qab cov yeeb nkab siab poob. Txawm hais tias qhov zoo thiab rov qab nkag mus, lub teeb emitting diode tsis tuaj yeem qhib, thiab tsis tuaj yeem kuaj pom. “R ×1 ”Thaum lub sij hawm cov ntaub ntawv rooj, 9V (los yog 15V) high-pressure batteries txuas nrog, uas yog siab tshaj qhov poob siab, yog li nws tuaj yeem siv los ntes lub teeb-emitting diode. Thaum lub sij hawm kuaj, ob lub ntsiav tshuaj txuas nrog ob lub taub hau ntawm lub teeb-emitting diodes. Tus ncej zoo txuas nrog) rau tus ncej zoo;. Tom qab ntawd txuas ob lub ntsiav tshuaj thiab lub teeb ci diodes. Lub sijhawm no, nws yog rov qab nkag. Yog tias qhov acupuncture tig los yog tsis txav, lub diodes ci ntsa iab tau raug puas tsuaj txawm tias lawv tig mus rau lub taub hau lossis thim rov qab. Txiav txim siab lub kaus mom straw LED zoo thiab tsis zoo ncej: sab hauv LED, cov pins txuas nrog lub bracket yog qhov tsis zoo electrodes, thiab cov pins ntawm cov hlua txuas me me yog qhov kev txiav txim zoo ncej 5050 thaj LED zoo ncej: tag nrho 5050 thaj LED yog square, nyob rau hauv plaub txoj cai ces kaum muaj ib tug me me scarce kaum, uas yog qhov chaw ntawm lub voj voog me me. Lwm lub kaum sab xis tsis muaj lub kaum sab xis me. Qhov kawg ntawm lub kaum sab xis me me yog qhov tsis zoo electrode, thiab lwm qhov kawg yog tus ncej zoo. Zhuhai TIANHUI Optoelectronics Technology Co., Ltd. yog txoj kev loj hlob ntawm LED teeb-emitting diode series ntawm cov khoom tsim, thaj LED ntau lawm ua, kev muag khoom thiab kev pab cuam -oriented ntiav lag luam. Cov khoom siv dav siv hauv computer, khoom siv sib txuas lus, khoom siv hluav taws xob thiab hluav taws xob, khoom siv hauv tsev thiab teeb pom kev zoo, automotive electronics, khoom siv kho mob thiab ntau qhov chaw tsim khoom.
