Microlens Array (MLA): Nws yog tsim los ntawm ntau lub micro-optical ntsiab lus thiab tsim kom muaj txiaj ntsig kho qhov muag nrog LED. Los ntawm kev teeb tsa thiab npog cov micro-projectors ntawm cov khoom thauj khoom, cov duab meej tag nrho tuaj yeem tsim tau. Cov ntawv thov rau MLA (los yog cov tshuab kho qhov muag zoo sib xws) muaj xws li cov kab sib txuas hauv fiber ntau txuas mus rau laser homogenization thiab kev pom zoo ntawm cov diode pawg ntawm tib lub wavelength. Qhov loj ntawm MLA yog li ntawm 5 mus rau 50 hli, thiab cov qauv hauv cov qauv tsim muaj tsawg dua 1 hli.
Cov qauv ntawm MLA: Cov qauv tseem ceeb yog raws li qhia hauv daim duab hauv qab no, nrog rau lub teeb ci LED hla dhau lub lens collimating, nkag mus rau MLA pawg thawj coj saib, thiab raug tswj thiab tawm los ntawm MLA pawg thawj coj saib. Vim tias qhov projection lub teeb lub khob hliav qab tsis loj, nws yog ib qho tsim nyog yuav tsum qaij qhov projection kom elongate tus qauv projected. Cov ntsiab lus tseem ceeb yog lub rooj tsavxwm MLA no, thiab cov qauv tshwj xeeb los ntawm LED lub teeb qhov chaw rau sab qhov projection yog raws li hauv qab no:
01 Thawj txheej micro lens array (tsim micro lens)
02 Chromium daim npog qhov ncauj qauv
03 iav substrate
04 Ob txheej micro lens array (projection micro lens)
Lub hauv paus ntsiab lus ua haujlwm tuaj yeem piav qhia los ntawm kev siv daim duab hauv qab no:
LED lub teeb qhov chaw, tom qab dhau los ntawm lub lens collimating, emits tib lub teeb mus rau lub tsom micro lens, tsim ib lub teeb cone, illuminating lub etched micro qauv. Cov qauv micro yog nyob rau ntawm lub dav hlau focal ntawm qhov projection micro lens, thiab tau muab tso rau ntawm qhov projection screen los ntawm qhov projection micro lens, tsim cov qauv projected.
Lub luag haujlwm ntawm lub lens hauv qhov xwm txheej no:
01 Ua kom pom tseeb thiab pov lub teeb
Lub lens tuaj yeem ua kom pom tseeb thiab lub teeb pom kev zoo, kom ntseeg tau tias cov duab kos duab lossis cov qauv pom tau meej meej ntawm qhov deb thiab cov ces kaum. Qhov no yog qhov tseem ceeb heev rau kev teeb pom kev tsheb tsheb vim nws ua kom ntseeg tau tias cov qauv tsim los yog cov cim tsim kom pom tseeb thiab yooj yim txheeb xyuas cov lus pom ntawm txoj kev.
02 Txhim kho qhov ci thiab qhov sib txawv
Los ntawm cov nyhuv tsom ntawm lub lens, MLA tuaj yeem txhim kho qhov ci ntsa iab thiab qhov sib txawv ntawm cov duab projected. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau kev tsav tsheb hauv lub teeb qis lossis hmo ntuj, vim tias muaj qhov ci ntsa iab, qhov sib txawv ntawm cov duab pom zoo tuaj yeem txhim kho kev nyab xeeb ntawm kev tsav tsheb.
03 Ua tiav cov teeb pom kev zoo ntawm tus kheej
MLA tso cai rau automakers los kho cov teeb pom kev zoo tshwj xeeb raws li hom thiab cov tswv yim tsim. Kev tswj xyuas meej thiab kev hloov kho ntawm lub lens ua rau cov neeg tsim khoom lag luam tsim ntau yam kev ua haujlwm tshwj xeeb thiab cov teebmeem animation uas txhim kho kev lees paub thiab tus kheej ntawm lub tsheb.
04 Dynamic teeb hloov kho
Qhov yooj ntawm lub lens tso cai rau MLA kom ua tiav cov teeb pom kev zoo. Qhov no txhais tau hais tias cov duab lossis cov qauv tuaj yeem hloov pauv hauv lub sijhawm tiag tiag kom haum rau cov xwm txheej sib txawv thiab cov xwm txheej. Piv txwv li, thaum tsav tsheb ntawm txoj kev loj, cov kab npaj yuav ntev dua thiab ncaj dua kom coj tus neeg tsav tsheb lub qhov muag zoo dua, thaum tsav tsheb ntawm txoj kev hauv nroog, yuav xav tau luv dua, dav dua los coj tus neeg tsav tsheb lub qhov muag zoo dua. Kho kom haum rau qhov chaw khiav tsheb nyuaj.
05 Txhim kho teeb pom kev zoo
Lens tsim tuaj yeem txhim kho txoj kev nthuav dav thiab kev faib tawm ntawm lub teeb, yog li txhim kho teeb pom kev zoo. Qhov no txhais tau hais tias MLA tuaj yeem txo qhov tsis tsim nyog lub zog poob thiab lub teeb muaj kuab paug thaum ua kom muaj qhov ci txaus thiab pom tseeb, thiab ua tiav cov teeb pom kev zoo ib puag ncig thiab txuag hluav taws xob.
06 Txhim kho qhov pom kev pom
High-zoo projection teeb pom kev zoo tsis tsuas yog txhim kho kev nyab xeeb ntawm kev tsav tsheb, tab sis kuj txhim kho tus neeg tsav tsheb qhov pom kev. Kev tswj xyuas meej thiab kev ua kom zoo ntawm lub lens tuaj yeem ua kom ntseeg tau tias cov duab kos duab lossis qauv muaj qhov pom kev zoo dua thiab kev nplij siab, txo cov neeg tsav tsheb qaug zog thiab pom kev cuam tshuam.
