Koj paub ntau npaum li cas txog glowing diodes? Niaj hnub no lub teeb-emitting diode kev lag luam xav tau yog dav. Cov uas siv rau hauv txoj kev teeb pom kev zoo, cov khoom siv kho mob, lub teeb tsheb, lub koob yees duab, lub teeb qhia lub zog thiab lwm yam kev lag luam tau koom nrog. Niaj hnub no, tus editor feem ntau xav piav qhia yuav ua li cas teeb lub teeb-emitting diodes. Coj lub teeb qhia ua piv txwv; Thaum peb lub luminous diode txuas nrog AC 220V, nws yog siv los ua lub zog ntsuas, thiab txoj kev yooj yim tshaj plaws yog txuas rau tam sim no -limiting resistor. Raws li hom teeb emitting diodes qhov loj ntawm. Lub teeb-emitting diode dav dav yog 2.8-3.4V, cov ntaub ntawv rau ntau yam xim txawv, thiab qhov voltage txawv. Tam sim no lub high brightness lub teeb emitting raj, tam sim no 10mA twb ci txaus. Rau lub teeb emitting diode, tus nqi tam sim no ua haujlwm yog 1mA-15mA. Qhov tshwj xeeb ci ci tuaj yeem hloov pauv los ntawm kev kho qhov loj ntawm qhov kev txwv tam sim no. Lub hauv paus ntsiab lus tseem ceeb ntawm lub teeb emitting diode yog tiag tiag los tsim ib qho kev cuam tshuam los ntawm qhov kawg voltage ntawm PN knot. Thaum txoj hauj lwm ntawm qhov zoo tsis zoo voltage txo, feem ntau ntawm cov cab kuj nyob rau hauv P cheeb tsam thiab N cheeb tsam kis mus rau lwm tus. Vim tias tus nqi hluav taws xob tsiv teb tsaws chaw muaj ntau dua li huab cua acupoint tsiv teb tsaws, ntau cov hluav taws xob kis mus rau thaj tsam P, tsim kev txhaj tshuaj ntawm cov neeg nqa khoom tsawg ntawm P cheeb tsam. Cov electrons no yog compounded los ntawm lub qhov tsua ntawm tus nqi, thiab lub zog tau txais thaum lub sij hawm composite yog tso tawm nyob rau hauv daim ntawv ntawm lub teeb lub zog. Qhov no yog lub hauv paus ntsiab lus ntawm PN knot glow. Cov saum toj no yog qee qhov kev piav qhia ntawm lub teeb pom kev zoo txog lub teeb emitting diode hnub no, uas yog cov ntsiab lus los ntawm tus editor. Yog tias koj xav paub ntau ntxiv txog lub teeb-emitting diode lossis yuav khoom, koj tuaj yeem tiv tauj ncaj qha rau cov neeg siv khoom hauv online, lossis hu xov tooj rau kev sab laj.
