[UVLED Feature] UVLED muaj cov yam ntxwv no

UVLED (UV lub teeb diode) luminous mechanism, efficiency, thiab cov yam ntxwv yog tam sim no tsis txwv rau high-pressure mercury teeb thiab halogen teeb. Kev kawm txuj ci ntawm semiconductors tau tso cai ultraviolet lub teeb diode rau lub teeb xim hauv ntau yam lag luam. Thiab raws li cov yam ntxwv ntawm kev siv hluav taws xob tsawg ntawm ultraviolet lub teeb diode nws tus kheej, nws ua rau cov txheej txheem uas tsis haum rau ultraviolet curing, thiab nws kuj tau los ua tshwj xeeb yog yooj yim thiab siv tau. Txawm li cas los xij, koj puas to taub qhov no ultraviolet lub teeb emitting diode? Cia peb saib nws: UVLED yog lub teeb ci ultraviolet emitting diode, uas kuj yog hom LED. , Tib 365-405. UVLED lub teeb emitting mechanism: Qhov kawg voltage ntawm PN knot ua ib qho teeb meem muaj peev xwm. Thaum qhov zoo tsis zoo voltage txo, feem ntau cov cab kuj nyob rau hauv P 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. UVLED luminous efficiency: Thaum ntxov tivthaiv kev loj hlob yog concentrated nyob rau hauv kev txhim kho nws internal quantum efficiency. Txoj hauv kev tseem ceeb yog txhawm rau txhim kho qhov zoo ntawm qhov barrier siv lead ua thiab hloov cov qauv ntawm barrier siv lead ua, kom lub zog hluav taws xob tsis yooj yim hloov mus rau thermal zog, thiab UVLED luminous efficiency yog indirectly txhim kho, kom lub luminous efficiency. ntawm UVLED tuaj yeem tau txais. Txog 70% ntawm qhov theoretical internal quantum efficiency, tab sis xws li internal quantum efficiency yuav luag ze rau theoretical txwv. UVLED cov yam ntxwv hluav taws xob: UVLED cov yam ntxwv hluav taws xob --- Kev sib raug zoo ntawm tam sim no thiab voltage UVLED cov yam ntxwv hluav taws xob --- UVLED voltage thiab kub kev sib raug zoo UVLED cov yam ntxwv hluav taws xob --- UVLED lub teeb-emitting lub kaum ntse ntse tswj tam sim no, cov yam ntxwv thauj khoom zoo ib yam li PN PN. UI nkhaus ntawm lub pob caus, qhov kev hloov me me ntawm qhov kev taw qhia zoo voltage yuav ua rau muaj kev hloov pauv ntau ntawm qhov zoo tam sim no (qib ntsuas), qhov rov qab xau tam sim no me me, thiab muaj qhov rov qab tawg voltage. Hauv kev siv tiag tiag, koj yuav tsum xaiv. UVLED qhov zoo voltage ua me me nrog qhov kub nce, nrog qhov kub tsis zoo coefficients. UVLED siv lub zog, ib feem ntawm kev hloov pauv mus rau lub teeb lub zog, qhov no yog qhov peb xav tau. Tus so yuav hloov mus rau hauv lub zog cua sov, kom lub pob caus kub nce. UVLED cov yam ntxwv kho qhov muag: UVLED muab lub teeb pom kev loj loj nrog lub teeb loj semi-dav. Vim hais tias lub zog sib txawv ntawm lub semiconductor txo qis nrog qhov kub thiab txias, lub ncov wavelength nws emits nce nrog qhov kub thiab txias, uas yog, spectrum liab hloov, uas yog, spectrum liab hloov, uas yog, spectrum liab hloov. Qhov kub coefficient yog 23. UVLED luminous brightness L thiab xa mus rau tam sim no. Tam sim no nce thiab lub teeb ci yog kwv yees li nce. Tsis tas li ntawd, qhov ci ci ci kuj muaj feem xyuam rau qhov kub ntawm ib puag ncig. Thaum qhov kub ntawm ib puag ncig yog siab, qhov sib xyaw ua haujlwm tau txo qis, thiab lub teeb emitting siv txo qis. UV LED thermal science yam ntxwv: UV LED thermal yam ntxwv --- Nyob rau hauv me me tam sim no ntawm UVLED wavelength thiab kub, UVLED kub nce yog tsis pom tseeb. Yog hais tias ib puag ncig kub siab, lub ntsiab wavelength ntawm UVLED yuav liab, lub brightness yuav txo, thiab luminous uniformity thiab sib xws yuav ua tsis zoo. Hauv particular, qhov kub thiab kev ruaj ntseg ntawm kev ntseeg siab thiab kev ruaj ntseg ntawm LEDs ntawm LEDs yog qhov tseem ceeb dua. Yog li kev tsim kom txias yog qhov tseem ceeb. Tianhui Technology Development Co., Ltd. siv cov thawj coj teeb hlaws hlaws, uas muaj kev cuam tshuam me me rau qhov kub thiab txias ib puag ncig thiab cov khoom zoo. Cov cuab yeej siv kho mob feem ntau suav nrog UVLED hlau qhov chaw teeb pom kev zoo, UVLED lub ntsej muag lub teeb qhov chaw, thiab UVLED dot teeb qhov chaw. Nws daim ntawv thov suav nrog UV kho tshuab ntawm ntau yam kev lag luam. Yog tias koj tsuas yog xav tau kho koj lub tshuab UV kho, koj tuaj yeem xav tiv tauj Tianhui. Kuv ntseeg tias yuav muaj qhov sib txawv! http:///list-19-1.html
