Tsav los ntawm cov yas tshiab, Taobao thiab Jingdong twb muaj ntau yam khoom siv tshuaj tua kab mob UV.
Raws li pom hauv daim duab hauv qab no, kev lag luam feem ntau faib cov kab hluav taws xob ultraviolet ua peb pawg: A, B, thiab C, uas yog ze rau ultraviolet (UVA), ultraviolet (UVB) thiab ultra-luv ultraviolet / tob ultraviolet (UVC). Ntawm lawv, UVC muaj lub zog loj tshaj plaws thiab muaj kev phom sij rau cov kab mob. Kev puas tsuaj heev.
Piv nrog UVB thiab UVA, UVC yog thawj qhov kev xaiv rau lub teeb pom kev noj qab haus huv; piv nrog tshuaj sterilization, UVC muaj qhov zoo ntawm kev ua kom tsis muaj menyuam thiab tsis muaj lwm yam tshuaj lom neeg.
Tuam Tshoj muaj tag nrho UVC semiconductor kev lag luam saw. UVC semiconductor tso rau pem hauv ntej cov kev xav tau siab dua ntawm nti, ntim tshuab thiab cov khoom ua haujlwm. Chip technology yog tam sim no lub ntsiab bottleneck thiab kev sib tw tseem ceeb ntawm kev sib sib zog nqus ultraviolet semiconductor technology. Kev lag luam' cov tuam txhab ua lag luam thiab UV LED segmentation Kev nqis peev ntawm cov tuam txhab ua lag luam hauv thaj teb tau nce ntxiv.
Cov kab mob sib kis tau nrawm rau kev txhim kho ntawm UVC semiconductor kev lag luam saw. Kev lag luam UVC tau nce los ntawm US $ 20 lab hauv xyoo 2008 txog US $ 100 lab hauv xyoo 2015, thiab US $ 144 lab hauv 2019. Xyoo no, nws tau ncaj qha ob npaug rau US $ 308 lab. Raws li Yole Developpement tsab ntawv ceeb toom, tau tsav los ntawm tus kabmob coronavirus, UVC kev lag luam tuaj yeem ncav cuag US $ 2.5 nphom hauv 2025, nrog rau kev loj hlob txhua xyoo ntawm 61% los ntawm 2019 txog 2025.
Los ntawm kev xav hauv tsev, nws kwv yees tias txij xyoo 2020 txog 2024, kev lag luam loj ntawm UVC sterilization modules hauv tshuab ntxhua khaub ncaws, tub yees, cua txias hauv tsev, thiab UVC cov khoom siv me me yuav nce los ntawm 174 lab yuan, 185 lab yuan, 194 lab yuan, thiab 1.5 billion yuan raws li 8.538 billion yuan, 8.927 billion yuan, 9.736 billion yuan thiab 3.5 billion yuan. Nws kwv yees tias los ntawm 2024, kev lag luam loj ntawm UVC sterilization modules hauv tsheb yuav ncav cuag 13.459 billion yuan.
Yog tias muaj peev xwm ua tau raws li qhov xav tau, tus lej no yuav muaj ntau dua.
Piv nrog UVA thiab UVB, UVC yog thawj qhov kev xaiv rau kev ua kom tsis muaj menyuam
Tam sim no muaj ob txoj hauv kev tseem ceeb kom tau txais UVC rau kev ua kom tsis muaj menyuam thiab tua kab mob: tsoos mercury teeb thiab ultraviolet LEDs. Piv nrog rau cov teeb mercury ib txwm muaj, UVC semiconductors muaj qhov zoo tshaj plaws: miniaturization, tsis muaj tshuaj lom, thiab siv tau yooj yim.
Tsis tas li ntawd, kev txhim kho ntawm UVC semiconductor txheej txheem yog qhov tseeb, thiab cov teeb meem kev lag luam txuas ntxiv mus.
Nyob rau hauv keeb kwm yav dhau no, tsoos ultraviolet mercury teeb tshuaj tua kab mob thiab cov khoom ua kom tsis muaj menyuam yuav raug hloov sai sai los ntawm UV LEDs.
Raws li Yole tsab ntawv ceeb toom, UV LED kev lag luam feem ntau yog tsav los ntawm UV curing daim ntaub ntawv. Txawm li cas los xij, tsis ntev los no Taiwan thiab cov tuam txhab loj loj tau nkag mus rau UVA LED kev lag luam hauv cov lej loj, ua rau muaj zog tus nqi siab, uas txwv kev loj hlob ntawm UVA LED kev lag luam.
UVC sterilization txoj cai
Ntawm qhov tod tes, raws li cov nqi khoom siv ($ / mW) pib mus txog qhov kev thov ntxov, UVC LED kev lag luam pib tshwm sim. Yole Développement' lub teeb pom kev zoo hauv lub xeev thiab cov chaw ua lag luam tus thawj coj Pars Mukish tau taw qhia, "Qhov tseeb, tus nqi ntawm UVC LEDs tau dhau los ntawm US $ 100 / mW hauv 2015 txog US $ 0.3-2 / mW hauv 2019. Qhov no yog qhov teeb meem loj rau feem ntau cov neeg muaj peev xwm ua ke nrog cov khoom lag luam siab. Hais txog nws, qhov no yog qhov pib tiag tiag."
2020 COVID-19 kev kis thoob qhov txhia chaw tau ua lub luag haujlwm ua lub luag haujlwm, tsim qee qhov kev siv zoo meej rau kev siv thev naus laus zis kom txhim kho nyob rau lub sijhawm luv luv.
Piv nrog UVA thiab UVB, UVC muaj zog nkag mus rau hauv lub cev tsis muaj zog thiab yuav tsis ua mob rau tib neeg lub cev, tab sis kev ua kom tsis muaj menyuam yuav luag zoo ib yam, yog li UVC tau dhau los ua thawj qhov kev xaiv rau kev ua kom tsis muaj menyuam thiab tshuaj tua kab mob.
Xyoo 2020, muaj qhov tsis txaus ntawm tag nrho UVC cov saw hlau, thiab tam sim no kev lag luam tab tom nrhiav txoj hauv kev los ua kom muaj peev xwm ntau lawm.
Cov txheej txheem ntawm kev sib sib zog nqus-ultraviolet semiconductors yog kwv yees tib yam li cov LEDs zoo tib yam, tab sis vim tias cov ntaub ntawv luminescent ntawm UV-LEDs txawv, cov khoom siv luminescent xaiv thiab cov ntawv ntim yuav txawv.
UVC semiconductor chips tuaj yeem muab faib ua ob ntu: substrate thiab epitaxial txheej: lub substrate feem ntau ua raws cov sapphire substrate siv xiav LED chips. Cov txheej txheej epitaxial suav nrog AIN template txheej, N-hom AIGaN txheej, ntau quantum zoo lub teeb-emitting txheej, electron thaiv txheej thiab P-hom GaN tiv tauj txheej.
Hauv cov txheej txheem nti, N-hom txheej txheej tau xau los ntawm lithography thiab etching, thiab N-hom thiab P-hom tau tsim rau hauv ohmic kev sib cuag nrog cov electrode los ntawm evaporation thiab alloying, thiab tom qab ntawd cov tub ntxhais me me yog txheeb los ntawm thinning thiab splitting, thiab ces tig mus rau Insulating silicon nti.
Tom qab ntau tshaj 10 xyoo ntawm kev tshawb fawb thiab kev loj hlob, lub sab nraud quantum efficiency ntawm sib sib zog nqus ultraviolet semiconductors hauv qab no 280nm tau tshaj 5%, cov coj luminous hwj chim yog ntau tshaj 5mW, thiab lub neej yog 5000h.
