OSRAM Opto Semiconductors tau hais tias nws yog thawj coj tsoomfwv pab pawg tshawb fawb los koom ua ke tsim lub zog loj, kev lag luam loj-taw qhia txog ultraviolet (UV) coj nti. Ultraviolet lub teeb tuaj yeem siv rau ntau yam kev siv, xws li kev kho (kev ziab), tshuaj tua kab mob, kev tsim khoom, tshuaj thiab kev ua neej nyob. Cov khoom siv tsis yog LED teeb, xws li mercury vapor teeb, muaj qee yam kev phom sij. Ntxiv mus, ntau UV LED chips ntawm kev ua lag luam tawm lub teeb ntawm qee qhov muaj txiaj ntsig wavelengths yam tsis muaj nqi kom zoo dua.OSRAM hais tias: "Lub hom phiaj ntawm peb txoj kev koom tes yog muab lub zog siab UV LEDs los npog ntau yam kev siv." cov LEDs no thaum kawg yuav hloov cov tsoos UV teeb qhov chaw uas muaj mercury. "OSRAM tau hais tias lub zog tshiab nti" kuj tseem tuaj yeem qhib cov ntawv thov tshiab."

UV yog qhov chaw tawm tshiab rau LED manufacturers. Cov neeg muab khoom muaj xws li rayvio, Nikkiso, tseem ceeb vio, sensor hluav taws xob tshuab, LG Innotek, thiab lwm yam.Cov kev tshawb fawb pab pawg coj los ntawm OSRAM yog nyiaj txiag los ntawm German Federal Ministry of Education thiab Research (BMBF). Nws vam tias yuav tsim cov qauv nrog lub wavelength ntawm 250nm txog 310nm los ntawm 2020, npog qee qhov UV-B thiab UV-C spectra. Feem ntau, qhov ntau ntawm lub teeb ultraviolet yog li 100 nm txog 380 lossis 400 nm. Nws yog qhov luv yoj tsis pom ib feem ntawm lub spectrum.

OSRAM tso tawm ib daim duab ntawm UV LED nti nyob rau hauv txoj kev loj hlob. Daim duab los ntawm Ferdinand Braun Institut, Leibniz Institut fur hochstfrequenztechnik (FBH) ntawm Leibniz Federation hauv lub teb chaws Yelemees.Ib qho kev sib tw yog los txhim kho kev ua tau zoo ntawm UV-B thiab UV-C spectra, uas yuav tsum tau ua kom tiav hauv cov ntaub ntawv thiab txuas ntxiv rau lwm yam. tshaj UV-A curing. OSRAM lub koom haum siv lub caij aluminium nitride (AlGaN). Phau Ntswv OSRAM, yog ib tug tub tswvyim: Ferdinand Braun Institut, Leibniz Institut fur hochstfrequenztechnik (FBH)); Berlin Institute of thetswv; LayTec AG; FBH uvphotonics NT GmbH.

OSRAM yog lub luag haujlwm rau thaj tsam ntawm 270-290-nm, FBH ua cov txheej txheem epitaxy nyob rau hauv thaj tsam ntawm 290-310nm, thiab ua cov txheej txheem epitaxial wafer rau hauv cov nti UV; Berlin Polytechnic University muaj kev txawj ntse hauv AlGaN teb, tsom rau thaj tsam ntawm 250-270 nm; Laytec muab thev naus laus zis los tswj cov kab mob epitaxial thiab ntshav etching; FBH optimized nti tsim, tsom rau siab tam sim no thiab txias txias. Tsis tas li ntawd, nws sau cov txheej txheem cov ntaub ntawv los ntawm lwm tus neeg koom tes thiab muab rau pab pawg tshawb fawb.OSRAM tau hais tias: "Lub teeb pom kev zoo ntawm LED tshiab yuav tsum tshaj 120 MW ntawm 300 ± 10 nm, 140 MW ntawm 280 ± 10nm thiab 80 MW ntawm 260 ± 10 nm. " pab pawg tshawb fawb tseem tab tom txhim kho qhov tseem ceeb rau kev laus tus cwj pwm ntawm LEDs kom lawv tuaj yeem ua haujlwm ntev thiab kev lag luam ntau dua. "
