Yadda za a Bambance Daban-daban Patch LED Positive da Korau Sanduna?

Na farko, ko da wane launi ne tabbatacce kuma an gyara shi mara kyau. Matsayin tabbatacce da mara kyau na facin LED: Yi la'akari da gaske a gaban facin LED. Akwai kwana a cikin murabba'i ko murabba'i. Akwai kusurwar kusurwa, kuma ɗayan gefen shine mummunan lantarki. Ingantattun sanduna mara kyau da mara kyau na beads na fitilar LED: Yi la'akari da gaske a gaban beads ɗin fitilar LED. A bangarorin biyu na fitilun fitilar LED, akwai ƙaramin kusurwa a ƙarshen ɗigon fitilar LED, kuma ƙarshen kusurwar yana da kyau kuma ɗayan ƙarshen shine mummunan electrode. LED bambaro hat fitilu suna bambanta da tabbatacce kuma korau electrodes na LED bambaro hat: Sabuwar LED ba a yanke, dogon kafar ne tabbatacce, sauran karshen ne korau electrode, kowane manufacturer zai bambanta. Idan an kunshe shi da patch 2512 Ko kuma ɗayan launuka shine na'urar lantarki mara kyau, ƙasa tana bayyana ta triangle, babban kai yana da kyau, ƙananan kai shine mummunan electrode, kuma babban kunshin yana da kyau da kuma korau. Na biyu, zaka iya amfani da agogon multimeter Ohm. Don bugun kira-style multimeter, daidaita zuwa “Om X1 ”Lokacin da diode ke haskakawa, ana haɗa agogon ja zuwa kyakkyawan ƙarshen SMDLED, kuma baƙar agogon yana haɗi zuwa ƙarshen SMDLED mara kyau. Na uku, saboda iyakokin buɗewar LED kusan 1.5-1.8V ne. Mai yiyuwa ne irin ƙarfin lantarki da multimeter na dijital ya bayar ba zai iya farawa ba. Don haka dubi alamar. Faci emitting dilate (SMDLED) yana da mummunan sandar sanda mai koren dige kuma yana da inganci. LED makamashi-ceton haske tabbatacce kuma korau Hanyar gane sandarka: Hanyar da aka fi amfani da ita ita ce hanyar gano multimeter. Lokacin amfani da multimeter don gano diode mai haske, dole ne ka yi amfani da shi “R ×L0K ”fayiloli. Matsin bututun diode mai wahala yana kusan 3V, kuma agogon duniya yana cikin “R ×Kulle ”Kuma lokacin da aka toshe juriya mai zuwa. Batirin da ke cikin tebur shine kawai 1.5V. Ƙarƙashin raguwar bugun bututu. Ko da kuwa tabbataccen damar da baya, ba za a iya kunna diode mai haske ba, kuma ba za a iya gano shi ba. “R ×1 ”A lokacin teburin fayil, 9V (ko 15V) manyan batura suna haɗawa, wanda ya fi girma fiye da raguwa, don haka ana iya amfani da shi don gano haske-emitting diode. A lokacin gwajin, allunan biyu suna haɗa su zuwa jagorar guda biyu na diodes masu fitar da haske. An haɗa madaidaicin sanda) zuwa sanda mai kyau;. Sannan haɗa allunan biyu da diodes masu haske.
