Lub Cheebtsam ntawm LED teeb: semiconductor khoom nti, dawb kua nplaum, Circuit Court board, epoxy resin, tub ntxhais hlau, plhaub.Lub teeb LED yog cov khoom siv hluav taws xob electroluminescent semiconductor nti, uas yog kho ntawm lub bracket nrog cov kua nplaum nyiaj los yog cov kua nplaum dawb, thiab tom qab ntawd txuas cov nti thiab lub rooj sib tham nrog cov nyiaj hlau los yog cov hlau kub.Ib puag ncig yog kaw nrog epoxy resin los tiv thaiv cov tub ntxhais hauv cov hlau.Kev ua haujlwm, thaum kawg nruab lub plhaub, yog li LED teeb muaj kev ua haujlwm zoo seismic.

LED teeb-emitting diode yog ib qho khoom siv hluav taws xob semiconductor uas tuaj yeem hloov hluav taws xob hluav taws xob mus rau qhov pom pom.Nws tuaj yeem hloov hluav taws xob ncaj qha rau hauv lub teeb.Lub plawv ntawm LED yog semiconductor nti, ib qho kawg ntawm nti yog txuas nrog rau kev txhawb nqa, ib qho kawg yog tus ncej tsis zoo, thiab lwm qhov kawg yog txuas nrog tus ncej zoo ntawm lub hwj chim, kom tag nrho cov nti yog encapsulated. los ntawm epoxy resin.

Lub teeb-emitting txoj cai ntawm LED teeb

Thaum cov tam sim no dhau los ntawm lub wafer, cov electrons nyob rau hauv N-hom semiconductor thiab lub qhov nyob rau hauv lub P-hom semiconductor hnyav sib tsoo thiab recombine nyob rau hauv lub teeb-emitting txheej los tsim photons, uas emit zog nyob rau hauv daim ntawv ntawm photons (uas yog. , lub teeb uas sawv daws pom).Semiconductors ntawm cov khoom sib txawv yuav tsim cov xim sib txawv ntawm lub teeb, xws li lub teeb liab, lub teeb ntsuab, lub teeb xiav thiab lwm yam.

Nruab nrab ntawm ob txheej ntawm semiconductors, electrons thiab qhov sib tsoo thiab recombine thiab tsim xiav photons nyob rau hauv lub teeb-emitting txheej.Ib feem ntawm lub teeb xiav tsim yuav raug tso tawm ncaj qha los ntawm txheej fluorescent;qhov seem seem yuav ntaus cov fluorescent txheej thiab cuam tshuam nrog nws los tsim cov duab daj.Cov photon xiav thiab daj photon ua haujlwm ua ke (sib xyaw) los tsim lub teeb dawb
