Osram ams hari ini mengumumkan TSL2585, sensor cahaya sekitar dengan UV eksklusif-Teknologi deteksi cahaya yang mendeteksi radiasi UV-A dalam cahaya alami untuk ruang-terbatas pada perangkat wearable dan aplikasi seluler lainnya.
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.
Pada saat yang sama, fotodioda TSL2585 mengadopsi pengaturan -tengah yang unik, yang memungkinkannya mendukung desain bezel yang sempit, mengintegrasikan deteksi kedipan sumber cahaya, dan dilengkapi dengan tiga modulator dengan laju pengambilan sampel hingga hingga 14kHz. Dengan memberikan penerangan dan informasi strobo cahaya sekitar ke kamera ponsel, kamera ini mendukung eksposur-otomatis cepat untuk kamera ponsel cerdas dan menghilangkan efek riak yang disebabkan oleh sorot pencahayaan sekitar.
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.
