Oremark UV Bead Structure

Puas yuav muaj coob tus neeg xav paub cov qauv sab hauv ntawm lub teeb diode teeb hlaws? Tib yam muaj tseeb rau Xiaobian, yog li kuv tshwj xeeb kom cov kws tshaj lij sau cov ntaub ntawv no rau koj siv. UV teeb diode hais txog. Lub teeb ultraviolet feem ntau yog siv los txheeb xyuas seb puas yog daim ntawv foos cuav, thiab qee cov khoom siv hluav taws xob ultraviolet teeb pom kev zoo yog nrov heev ntawm cov koom haum hmo ntuj thiab tog. Lawv yog siv los ua cov tshuaj fluorescent emit ntau lub teeb ci. Nws cov qauv yooj yim yog cov khoom siv semiconductor ntawm electrostatic glowing, muab tso rau ntawm lub txee ua, thiab tom qab ntawd muab khi nrog epoxy resin nyob ib puag ncig nws los tiv thaiv cov tub ntxhais hauv cov hlau. Yog li ntawd. Qhov tseem ceeb ntawm lub emitting diode yog ib nti uas muaj P-type semiconductor thiab N-type semiconductor. Muaj cov txheej txheem hloov pauv ntawm P-type semiconductor thiab N-type semiconductor, hu ua PN knot. Hauv PN knot ntawm qee yam khoom siv semiconductor, cov khoom me me - hauv -load thiab feem ntau cov cab kuj raug tso tawm thaum cov cab kuj raug tso tawm hauv daim ntawv ntawm lub teeb, kom lub zog hluav taws xob ncaj qha hloov mus rau lub teeb lub zog rau lub teeb lub zog. Pn knot ntxiv rau qhov hluav taws xob rov qab, ob peb lub cab kuj nyuaj rau txhaj, yog li nws tsis tawm lub teeb. Qhov no diode ua los ntawm kev txhaj tshuaj electrophoretic teeb pom kev zoo yog hu ua luminous diode, uas feem ntau hu ua LED. Thaum nws nyob hauv lub xeev ua haujlwm zoo (uas yog, ob qhov kawg ntxiv rau qhov zoo voltage), tam sim no ntws los ntawm LED anode mus rau cathode, semiconductor crystals emit lub teeb ntawm ultraviolet mus rau infrared xim. Cov yam ntxwv ntawm ultraviolet lub teeb diode; 1) 5 hli liab qab lub teeb siv iav ntim thiab npib tsib xee-plated alloy plhaub, uas ntxiv txhim kho lub teeb pom kev zoo ntawm lub teeb liab, txo qhov lwj ntawm lub teeb liab, ncua kev pab cuam lub neej ntawm kev pabcuam, thiab txuas ntxiv lub neej kev pabcuam. 2) Ob tus pins siv cov tshuab kub-plated. 3) Siab siab lub zog. 4) ruaj khov thiab txhim khu kev qha zoo.
