[Parameters] Ob peb qhov tseem ceeb ntawm UVLED Lamp Beads

UVLED yog cov khoom siv hluav taws xob semiconductor luminous. Zoo li feem ntau siv teeb pom kev zoo LEDs, nws cov tub ntxhais yog PN knot. Lub ntsiab emitting mechanism yog hais tias thaum PN knot ntxiv nrog ib tug zoo voltage, lub peev xwm ntawm PN knot yuav txo. Lub sijhawm no, cov hluav taws xob hauv cheeb tsam N tau kis mus rau thaj tsam P, thiab lub qhov tsua hauv P cheeb tsam kis mus rau thaj tsam N, tab sis tus naj npawb ntawm yav dhau los nyob deb ntawm qhov kawg ntawm lub tom kawg. Nws yog qhov loj dua, yog li cov electrons yuav tsum sib xyaw ua ke hauv ntau qhov ntau, thiab lub zog tsim los ntawm cov khoom sib xyaw yog tso tawm hauv daim ntawv ntawm lub teeb. UVLED muaj cov yam ntxwv tseem ceeb hauv qab no: 1. Lub wavelength UVLED muaj ib lub ncov wavelength, UVA band yog 365nm, 385nm, 395nm, thiab lwm yam. Hauv qab no yog daim ntawv qhia 365nm wavelength. 365nm tsuas yog nws lub ncov wavelength xwb. Bandwidth, txog 360nm-370nm. Lub wavelength ntawm UVLED kuj yuav drifted los ntawm lwm yam hauv lub sij hawm luminous txheej txheem. Nws yog feem ntau yog ob yam: tam sim no thiab kub. Raws li pom hauv daim duab, peb tuaj yeem pom tias nrog qhov nce ntawm qhov tam sim no thiab qhov kub thiab txias, lub wavelength yuav maj mam loj dua. Yog li ntawd, thaum tsim cov txheej txheem, peb yuav tsum xav txog qhov tam sim no tus nqi thiab qhov kub thiab txias ntawm cov hlaws dai thaum lub sijhawm ua haujlwm. Feem ntau, peb ua haujlwm ze ntawm lub ncov wavelength. 2. Optical zog (irradiated zog) Optical zog hais txog lub teeb ntawm lub teeb hlaws dai. Qhov sib txawv wavelengths sib txawv vim qhov sib txawv ntawm qhov sib txawv ntawm electro-light conversion. Feem ntau, qhov luv luv lub wavelength nyob rau hauv cov cuab yeej siv tam sim no, qhov kev hloov pauv ntawm electro-optical qis dua. Lub sijhawm qis dua, qhov siab dua lwm qhov, qhov siab dua UVA's LED feem ntau luminous dua li ntawm UVC LED. Cov hauv qab no yog kev sib raug zoo ntawm optical hwj chim thiab tam sim no ntawm ib tug tej yam UVLED: 3. Lub ntsiab lus ntawm VFVF yog pem hauv ntej Voltage, uas yog, thaum lub diode yog tag nrho tsav, lub diode nws tus kheej PN knot yog IF. Qhov txawv voltage. Thaum VF ntawm UVLED feem ntau tshwm sim, thaum muab cov hlaws teeb hlaws nrog cov wavelengths sib txawv, UVA lub teeb hlaws feem ntau yog 3.5V-3.8V, thiab UVC lub teeb hlaws feem ntau yog 5V-7V. Thaum tib lub chaw tsim khoom tsim cov khoom qub, VF feem ntau tswj hwm VF, kom cov chaw tsim khoom siv cov cuab yeej yuav raug cais tawm thiab tswj xyuas thaum lub thaj. Tam sim no ntxiv rau lub teeb hlaws tsis yog tib lub sijhawm, thiab nws VF kuj hloov pauv. Feem ntau hais lus, qhov loj dua tam sim no, qhov loj dua VF, raws li qhia hauv daim duab hauv qab no: Tianhui's UVLED nto lub teeb qhov chaw siv cov khoom siv los ntawm UVLED cov hlaws dai, cov khoom siv hluav taws xob zoo tsis tu ncua, zoo heev thermal dissipation ua ke nrog zoo heev tshav kub dissipation tsim, nrog rau qhov zoo ntawm cov qauv compact, siab ntseeg siab, thiab siab stability. Cov khoom tau txais txiaj ntsig zoo los ntawm cov neeg siv khoom.
