OSRAM Opto Semiconductors e boletse hore e etelletse pele sehlopha sa lipatlisiso se tšehelitsoeng ka lichelete ke mmuso ho nts'etsapele chip e etelletseng pele ea matla a phahameng, e shebaneng le 'maraka oa ultraviolet (UV). Leseli la Ultraviolet le ka sebelisoa lits'ebetsong tse fapaneng, joalo ka ho phekola (ho omisa), ho bolaea likokoana-hloko, tlhahiso, meriana le saense ea bophelo. Mehloli ea mabone a khale ao e seng a LED, joalo ka mabone a mercury vapor, a na le likotsi tse itseng tse ka bang teng. Ho feta moo, li-chips tse ngata tsa UV LED 'marakeng li hlahisa leseli ka maqhubu a mang a bohlokoa ntle le litšenyehelo tse ntle.OSRAM e itse: "sepheo sa tšebelisano ea rona ke ho fana ka li-LED tsa mahlaseli a phahameng a matla ho koahela lits'ebetso tse fapaneng." li-LED tsena qetellong li tla nka sebaka sa mohloli oa khanya oa UV oa setso o nang le mercury. "OSRAM e boletse hore chip e ncha e nang le matla a phahameng" e ka boela ea bula libaka tse ncha tsa kopo.

UV ke sebaka se hlahang bakeng sa bahlahisi ba LED. Bafani ba thepa ba kenyeletsa rayvio, Nikkiso, vital vio, sensor electronic technology, LG Innotek, joalo-joaloSehlopha sa lipatlisiso se etelletsoeng pele ke OSRAM se tšehetsoa ka lichelete ke Lekala la Federale la thuto le Lipatlisiso la Jeremane (BMBF). E tšepa ho hlahisa prototype e nang le leqhubu la bolelele ba hoo e ka bang 250nm ho 310nm ka 2020, e koahelang mahlaseli a mang a UV-B le UV-C. Ke leqhubu le lekhutšoane le sa bonahaleng karolo ea spectrum.

OSRAM e lokolotse foto ea chip ea UV LED e ntseng e ntlafatsoa. Senepe se tsoa ho Ferdinand Braun Institut, Leibniz Institut fur hochstfrequenztechnik (FBH) of Leibniz Federation in Germany.E 'ngoe ea liqholotso ke ho ntlafatsa ts'ebetso ea UV-B le UV-C spectra, e hlokang katleho ea lisebelisoa le ho atolosa lisebelisoa tse ling. ho feta UV-A pheko. The team led by OSRAM is using gallium aluminum nitride (AlGaN) material system.In addition to OSRAM, the other four research groups are: Ferdinand Braun Institut, Leibniz Institut fur hochstfrequenztechnik (FBH)); Berlin Institute of technology; LayTec AG； And FBH split uvphotonics NT GmbH.

OSRAM e ikarabella bakeng sa mefuta e mengata ea 270-290-nm, FBH e sebetsana le epitaxy ka har'a mefuta e mengata ea 290-310nm, 'me e sebetsana le epitaxial wafer ka har'a chip ea UV; Univesithi ea Berlin Polytechnic e na le boiphihlelo tšimong ea AlGaN, e shebaneng le mefuta ea 250-270 nm; Laytec e fana ka theknoloji ea ho laola litsamaiso tsa epitaxial le plasma etching; Moralo oa chip o ntlafalitsoeng oa FBH, o tsepamisitse maikutlo ho pholiso e phahameng ea hajoale le e sebetsang hantle. Ho feta moo, e bokella lintlha tsa ts'ebetso ho tsoa ho balekane ba bang mme e fana ka eona ho sehlopha sa lipatlisiso.OSRAM e itse: "khanya ea LED e ncha e lebelletsoe ho feta 120 MW 300 ± 10 nm, 140 MW ho 280 ± 10 nm le 80 MW ho 260 ± 10 nm." sehlopha sa bafuputsi se boetse se etsa lintlafatso tse kholo boitšoarong ba botsofali ba li-LED e le hore li ka sebetsa nako e telele le moruo.
