LED nti yog dab tsi|LED lub zog txuag hluav taws xob
LED nti yog ib qho khoom siv hluav taws xob semiconductor uas tuaj yeem hloov hluav taws xob ncaj qha rau hauv lub teeb. Lub plawv ntawm LED nti yog ib qho semiconductor wafer, ib kawg ntawm lub wafer txuas nrog lub bracket, ib kawg yog qhov tsis zoo electrode, thiab lwm qhov kawg yog txuas nrog qhov zoo electrode ntawm lub hwj huam mov, kom tag nrho LED nti. yog encapsulated los ntawm epoxy resin.
LED nti, tseem hu ua LED teeb-emitting nti, yog lub hauv paus tseem ceeb ntawm LED lub zog txuag teeb, uas tseem hu ua PN kev sib tshuam.
Nws lub luag haujlwm tseem ceeb yog hloov hluav taws xob rau hauv lub teeb lub zog, thiab cov khoom tseem ceeb ntawm cov nti yog monocrystalline silicon.
Lub semiconductor wafer muaj ob feem, ib feem yog P-hom semiconductor, nyob rau hauv uas lub qhov dominate, thiab lwm yam kawg yog N-hom semiconductor, qhov twg electrons feem ntau. Tab sis thaum ob lub semiconductors txuas nrog, PN kev sib tshuam yog tsim los ntawm lawv. Thaum cov tam sim no ua rau lub wafer los ntawm cov hlau, cov electrons yuav raug thawb mus rau P cheeb tsam, qhov twg cov electrons thiab qhov recombine, thiab ces emit zog nyob rau hauv daim ntawv ntawm photons, uas yog lub hauv paus ntsiab lus ntawm LED nti teeb-emitting.
Lub wavelength ntawm lub teeb, uas kuj yog xim ntawm lub teeb, yog txiav txim los ntawm cov khoom uas tsim PN hlws ris.
