Idrayivu yokuhlola i-Audi yethule isizukulwane esisha sezibani ze-laser

Ubuchwepheshe beMatrix laser bukhanyisa kahle umgwaqo, buvumela izinhlobo ezintsha zemisebenzi yokusiza ukukhanya futhi yathuthukiswa ngokubambisana no-Osram noBosch.

Ubuchwepheshe beMatrix laser bususelwa kubuchwepheshe beLaserSpot bemithombo emikhulu yokukhanya okwenziwe ngogongolo okwethulwe ngabakwa-Audi ekukhiqizeni kwi-Audi R8 LMX *. Ngokokuqala ngqa, ama-lasers akhanyayo avumele ubuchwepheshe be-projector ukuthi buhlanganiswe namalambu ahlanganisiwe futhi anamandla.

Ubuchwepheshe obusha bususelwa ku-micromirror ehambisa ngokushesha eqondisa kabusha i-laser beam. Ngezivinini zokuhamba eziphansi, umsebe okhanyayo usakazeka endaweni enkulu yokuqagela futhi umgwaqo ukhanyiswa ebangeni elibanzi kakhulu. Ngesivinini esikhulu, i-engeli yokuvula incane, futhi ukukhanya nobubanzi bokukhanya kukhuphuke kakhulu. Lokhu kuyinzuzo ebaluleke kakhulu lapho ushayela emgwaqeni omkhulu. Ngaphezu kwalokho, ugongolo lwalezi zibani lungasakazeka ngokunembile. Lokhu kusho ukuthi ukukhanya ezindaweni zokukhanyisa ezahlukahlukene kungashintshwa ngokulawula ngokunembile isikhathi sokufiphala nokukhanyisa kuzo.

Enye into entsha wukwenza kusebenze okukhaliphile nokusheshayo kanye nokuvalwa kwe-laser diode kuye ngokuthi isibuko simi kuphi. Lokhu kuvumela i-beam yokukhanya ukuthi inwebe futhi ifinyeze ngamandla futhi ngokushesha okukhulu. Njengama-LED amanje e-Audi Matrix, umgwaqo uhlezi ukhanya ngaphandle kokucwasa abanye abasebenzisi bomgwaqo. Umehluko obalulekile ukuthi ubuchwepheshe be-laser ye-matrix bunikeza ukulungiswa okunembe nakakhulu nokuhle kakhulu okuguquguqukayo ngakho-ke izinga eliphezulu lokusetshenziswa kokukhanya, okuthuthukisa ukuphepha emgwaqeni.

Kubuchwepheshe obusha, iphrojekthi ye-OSRAM eluhlaza okwesibhakabhaka ye-laser diode iphrojekthi ye-nanometer engu-450 kwisibuko esinyakazayo esisheshayo esingu-XNUMX millimeter. Lesi sibuko siqondisa kabusha ukukhanya kwe-laser eluhlaza okwesibhakabhaka ku-transducer, okukuguqula kube ukukhanya okumhlophe bese kukuqondisa emgwaqweni. Isibuko esisetshenziselwe le njongo, esinikezwe nguBosch, siyisistimu ye-micro-optical elawulwa nge-elektrikhi esebenzisa ubuchwepheshe be-silicon. Ihlala isikhathi eside ngokwedlulele futhi inempilo ende kakhulu. Izakhi ezifanayo zisetshenziselwa ama-accelerometer nezilawuli ezinhlelweni zokulawula ukuzinza kwe-elekthronikhi.

Kumklamo weminyaka emithathu we-iLaS, abakwa-Audi basebenzisana kakhulu neBosch, Osram kanye neLichttechnischen Institut (LTI), okuyingxenye yeKarlsruhe Institute of Technology (KIT). Le phrojekthi ixhaswe yi-German Federal Ministry of Education and Science.

I-Audi ibambe iqhaza elibalulekile kwezobuchwepheshe bokukhanyisa izimoto iminyaka eminingi. Eminye yemikhiqizo emisha eyisihluthulelo:

• 2003: I-Audi A8 * enamalambu ahambisanayo.

• 2004: I-Audi A8 W12 * enamalambu asebenza emini e-LED.

• 2008: I-Audi R8 * enamalambu agcwele e-LED

• 2010: I-Audi A8, lapho amalambu alawulwa khona kusetshenziswa idatha evela ku-navigation system.

• 2012: I-Audi R8 enezimpawu zamandla eziguqukayo

• 2013: I-Audi A8 enamalambu amalambu e-LED

• 2014: I-Audi R8 LMX enobuchwepheshe be-LaserSpot high beam
