Osram ams julkisti tänään TSL2585:n, ympäristön valoanturin, jossa on patentoitu UV-valontunnistustekniikka, joka havaitsee UV-säteilyn luonnollisessa valossa avaruusrajoitteisille puetettaville ja muille mobiilisovelluksille.
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.
Samanaikaisesti TSL2585:n valodiodi käyttää ainutlaatuista off-center-järjestelyä, jonka ansiosta se tukee kapeaa kehysrakennetta, integroi valonlähteen välkynnän havaitsemisen ja on varustettu kolmella modulaattorilla, joiden näytteenottotaajuus on suurempi. 14 kHz asti. Tarjoamalla valaistuksen ja ympäristön valon välähdystiedot puhelimen kameralle, se tukee nopeaa automaattista -valotusta älypuhelimen kameroille ja eliminoi ympäristön valaistuksen aiheuttamat värähtelyt.
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.
