Lub hauv paus ua haujlwm ntawm lub tsheb LED teeb
Lub tsheb LED teeb, tseem hu ua lub teeb -emitting diode teeb, yog cov khoom siv teeb pom kev zoo uas hloov hluav taws xob hluav taws xob mus rau lub teeb hluav taws xob siv cov khoom siv semiconductor. LED teeb muaj qhov zoo xws li kev ua haujlwm siab, kev ua neej ntev, kev siv hluav taws xob tsawg, thiab ib puag ncig tus phooj ywg, thiab yog li ntawd tau siv dav hauv cov tsheb teeb pom kev zoo niaj hnub no.
Lub hauv paus ntsiab lus ua haujlwm ntawm LED teeb yog raws li lub teeb -emitting nyhuv ntawm PN junction. Thaum tam sim no dhau los ntawm PN kev sib tshuam, electrons thiab qhov recombine, tso lub zog thiab emitting lub teeb, yog li ua tiav cov teeb pom kev zoo.
Cov cuab yeej thiab cov khoom siv yuav tsum tau kho lub tsheb LED teeb
Kev kho tsheb LED teeb yuav tsum muaj qee yam khoom siv thiab cov khoom tsim nyog. Ua ntej, koj yuav xav tau qee yam cuab yeej yooj yim, xws li cov ntsia hlau ntsia hlau, multimeters, soldering hlau, thiab cua kub ntsws tubing. Cov cuab yeej no yuav raug siv rau kev tshem tawm lub teeb taws, ntsuas lub voj voog, thiab hloov cov chips LED.
Qhov thib ob, nyob ntawm qhov ua txhaum tshwj xeeb, koj yuav tsum tau npaj cov chips LED tshiab, cov tsav tsheb, fuses, thiab lwm yam khoom siv. Piv txwv li, yog tias lub teeb puas lawm, koj yuav tsum tau yuav lub siab - zoo LED qhov muag teev uas phim tus qauv qub rau lub tsheb. Thaum hloov lub teeb, nco ntsoov xyuas kom lub tsheb raug kaw kom tsis txhob muaj kev pheej hmoo ntawm hluav taws xob poob.
