Osram ams kunngjorde i dag TSL2585, en omgivelseslyssensor med proprietær UV-En lysdeteksjonsteknologi som oppdager UV-A-stråling i naturlig lys for plass-begrensede bærbare og andre mobilapplikasjoner.
While Earth's atmosphere blocks the UV-C portion of sunlight, UV-A and UV-B radiation can reach the Earth's surface. Among them, UV-A radiation accounts for about 90 percent of the ultraviolet components reaching the earth's surface, and can penetrate deeply into the lower epidermis of the skin, causing serious health effects in some cases, such as weakening connective tissue, accelerating skin aging, increasing risk of skin cancer, etc.
Using ams Osram's new ambient light sensor, smartwatch users can receive immediate warnings when the UV-A radiation levels in the environment are too high.
Barry Guo, Marketing Manager at ams Osram, said that the TSL2585 has a short integration time and high sensitivity, and can reliably detect ambient light even under low transmittance materials and OLED screens. Its small size package and design greatly increase manufacturers' industrial design freedom.
According to reports, this ambient light sensor uses ams Osram's advanced interference filters, which can be precisely deposited on each photodiode pixel to create a 315nm-400nm UV-A channel, human eye responsive photopic vision channel and IR channels to provide necessary information for indoor and outdoor identification, UV index calculation and ambient illuminance detection.
Samtidig har fotodioden til TSL2585 et unikt off-arrangement som gjør at den støtter en smal rammedesign, integrerer lyskildeflimmerdeteksjon og er utstyrt med tre modulatorer med en samplingshastighet på opptil til 14 kHz. Ved å gi strobeinformasjon om belysningsstyrke og omgivelseslys til telefonkameraet, støtter det rask automatisk-eksponering for smarttelefonkameraer og eliminerer ringvirkningen forårsaket av strober fra omgivelseslys.
In addition, the TSL2585 is packaged in an ultra-flat package with a compact size of only 2.0 mm x 1.0 mm x 0.35 mm for space-saving system design, helping manufacturers design extremely compact devices; operating voltage of 1.8V, when not operating The current is only 0.7µA.
