Digital Sun Protection Nrog Ultra-me me Ambient Lub Teeb Sensor Nrog UVA Tshawb Pom

Ams Osram tau Lanuched ib puag ncig lub teeb sensor nrog lub tswv yim UV-A lub teeb pom kev ua haujlwm. Kev soj ntsuam cov cim tseem ceeb xws li mem tes lossis oxygen saturation hauv cov ntshav ntawm cov xov tooj smartphones thiab smartwatches tau muaj rau ntau xyoo.Qhov sib thooj UV channel ntawm TSL2585 ntawm ams OSRAM tuaj yeem kuaj xyuas tus nqi ntawm UV-A hluav taws xob hauv lub hnub ci ntuj. Qhov no ua rau cov neeg siv tau ceeb toom ntawm ntau dhau UV-A hluav taws xob. Ua tsaug rau nws qhov loj me me, lub sensor yog qhov tsim nyog rau qhov chaw txwv tsis pub hnav thiab lwm yam kev siv mobile.

Ntawm cov khoom zoo sib xws, lub compact TSL2585 ambient light sensor (ALS) yog thawj cov khoom los txhawb UV-A hluav taws xob nrhiav kom pom. Ua tsaug rau UV-A nrhiav pom ntawm ALS tshiab, cov neeg siv tuaj yeem tau txais kev ceeb toom ntxov ntawm kev raug UV-A ntau dhau. High-rhiab heev photopic thiab infrared raws tuaj yeem ua tiav qhov tseeb ntawm lub teeb pom kev zoo tom qab cov ntaub ntawv xa tawm qis thiab OLED cov lus.

Txawm hais tias UV-C ib feem ntawm lub hnub ci yog thaiv los ntawm lub ntiaj teb' qhov cua, UV-A thiab UV-B hluav taws xob tseem tuaj yeem ncav cuag lub ntiaj teb' qhov chaw. UV-B hluav taws xob tsuas yog nkag mus rau sab sauv ntawm daim tawv nqaij thiab ua rau tshav ntuj. UV-A hluav taws xob suav txog li 90% ntawm cov khoom siv ultraviolet uas ncav cuag lub ntiaj teb, tuaj yeem nkag mus tob rau hauv cov khaubncaws sab nraud povtseg ntawm daim tawv nqaij, thiab qee zaum tuaj yeem muaj kev cuam tshuam loj rau kev noj qab haus huv-los ntawm kev ua kom tsis muaj zog ntawm cov ntaub so ntswg. kom sai ntawm daim tawv nqaij laus, qhov ua tau ntawm daim tawv nqaij mob cancer kuj siab dua. Nrog ams OSRAM tus tshiab ambient light sensor, smartwatch cov neeg siv tam sim no tuaj yeem ceeb toom thaum UV-A koob tshuaj nyob hauv ib puag ncig siab dhau.

TSL2585 integrates optical flicker detection on-chip, thiab yog txawm peem rau nrog peb modulators nrog ib tug ceev sampling tus nqi txog li 14 kHz. Los ntawm muab cov ntaub ntawv illuminance thiab ambient lub teeb flicker cov ntaub ntawv rau lub xov tooj lub koob yees duab, nws txhawb lub ceev tsis siv neeg kis ntawm lub xov tooj lub koob yees duab ntse thiab tshem tawm cov banding nyhuv tshwm sim los ntawm lub ambient lub teeb flicker.

Lub compact loj ntawm ib lub pob loj heev ntawm tsuas yog 2.0 hli x 1.0 hli x 0.35 hli tso cai rau qhov chaw txuag qhov system tsim, pab cov tuam txhab ntawm cov khoom siv compact heev. Lub sensor tuaj yeem ua haujlwm ntawm 1.8V thiab haus tsuas yog 0.7µA thaum tsis ua haujlwm.
