UVLEDs, ib pawg ntawm lub teeb-emitting diodes (LEDs), emit lub teeb nyob rau hauv lub ultraviolet spectrum es tsis txhob pom lub teeb zoo li ib txwm LEDs. Lub UV spectrum tau muab faib ua peb pawg tseem ceeb raws li lub wavelength: UVA, UVB, thiab UVC. Hauv qhov blog no, peb yuav tshawb txog lub luag haujlwm tseem ceeb ntawm Hlau Core Printed Circuit Board (MCPCB) hauv UVLED thev naus laus zis, qhia txog nws qhov tseem ceeb hauv kev txhim kho kev ua haujlwm, kev tswj kom sov, thiab tag nrho lub neej.
UVA (315-400nm):
UVA, tseem hu ua ze-ultraviolet, emits ntev-yoj ultraviolet lub teeb. Nws nyob ze rau qhov pom lub teeb pom kev zoo tshaj plaws thiab pom cov ntawv thov hauv UV kho, kev tshuaj ntsuam xyuas, kev tshawb pom cuav, tanning txaj, thiab lwm yam.
UVB (280-315 nm):
UVB emits nruab nrab-yoj ultraviolet lub teeb thiab muaj npe nrov rau nws cov teebmeem lom. Nws yog siv nyob rau hauv kev kho mob, phototherapy, kev siv tshuaj tua kab mob, thiab txawm rau inducing vitamin D synthesis nyob rau hauv daim tawv nqaij.
UVC (100-280 nm):
UVC emits luv-yoj ultraviolet lub teeb thiab muaj cov khoom muaj zog tua kab mob. Nws cov ntawv thov suav nrog kev lim dej, tshuaj tua kab mob hauv huab cua, ua kom tsis muaj menyuam, thiab tshem tawm cov kab mob, kab mob, thiab lwm yam kab mob.
UVLEDs feem ntau ua haujlwm nyob rau hauv qhov kub ntawm -40 ° C txog 100 ° C (-40 ° F txog 212 ° F). Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov kub ntau dhau tuaj yeem cuam tshuam rau kev ua haujlwm, kev ua haujlwm, thiab kev ua neej nyob ntawm UVLEDs. Yog li ntawd, cov txheej txheem kev tswj xyuas thermal tsim nyog xws li cov dab dej kub, cov ntaub qhwv thermal, thiab cov cua txaus txaus feem ntau yog ua haujlwm los ua kom cov cua sov thiab ua kom UVLEDs nyob rau hauv qhov ntsuas kub zoo.
Hauv kev xaus, MCPCB ua lub luag haujlwm tseem ceeb hauv UVLED thev naus laus zis, muab cov txiaj ntsig tseem ceeb xws li kev ua kom muaj cua sov zoo, txhim kho thermal conductivity, kev ntseeg siab hauv qhov chaw hnyav, thiab kev sib cais hluav taws xob. Cov khoom zoo no yog qhov tseem ceeb tshaj plaws rau kev ua haujlwm siab tshaj UVLED, ua kom lub neej ntev, thiab tswj kev ua haujlwm kom zoo. Qhov tseem ceeb ntawm MCPCB yog nyob rau hauv nws lub peev xwm los txhim kho kev ua tau zoo, txhim kho kev tswj kom sov, thiab muab lub hauv paus txhim khu kev qha rau UVLED systems. Yog tsis muaj MCPCB, UVLED daim ntawv thov yuav ntsib teeb meem hauv cov cua kub dissipation, kev ua haujlwm ruaj khov, thiab kev nyab xeeb tag nrho.
