LED (Lub Teeb Emitting Diode) Lub teeb emitting diode yog ib hom khoom siv hluav taws xob semiconductor, uas tuaj yeem hloov hluav taws xob ncaj qha rau hauv lub teeb. Lub plawv ntawm LED yog semiconductor nti. Ib qho kawg ntawm cov nti yog txuas nrog lub bracket, ib qho kawg yog tus ncej tsis zoo, thiab lwm qhov kawg yog txuas nrog tus ncej zoo ntawm lub zog, kom tag nrho cov nti yog encapsulated los ntawm epoxy resin.
Semiconductor chips yog tsim los ntawm peb qhov chaw, ib qho yog p-hom semiconductor, nyob rau hauv uas lub qhov dominates, thiab lwm yam kawg yog n-hom semiconductor. Nyob rau sab no, nws feem ntau yog hluav taws xob, thiab qhov nruab nrab feem ntau yog quantum zoo nrog lub sij hawm ntawm 1 mus rau 5 cycles.Thaum tam sim no ua rau lub nti los ntawm cov hlau, cov electrons thiab qhov yuav raug thawb mus rau quantum zoo.
Nyob rau hauv lub quantum zoo, cov electrons thiab qhov compound thiab ces emit zog nyob rau hauv daim ntawv ntawm photons. Qhov no yog lub hauv paus ntsiab lus ntawm LED luminescence.Lub wavelength ntawm lub teeb, uas yog, xim ntawm lub teeb, yog txiav txim los ntawm cov khoom uas tsim pn hlws ris.
