Osram ams hnub no tau tshaj tawm TSL2585, lub teeb pom kev nyob nruab nrab nrog UV tus tswv-Lub teeb pom kev siv thev naus laus zis uas kuaj pom UV-Ib hluav taws xob hauv lub teeb ntuj rau qhov chaw- txwv tsis pub hnav thiab lwm yam kev siv mobile.
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.
Nyob rau tib lub sijhawm, lub photodiode ntawm TSL2585 tau txais qhov tshwj xeeb tawm - qhov chaw nruab nrab, uas ua rau nws txhawb nqa nqaim bezel tsim, sib koom ua ke lub teeb pom kev flicker, thiab tau nruab nrog peb lub modulators nrog tus nqi piv txwv ntawm nce. rau 14 kHz. Los ntawm muab illuminance thiab ambient lub teeb strobe cov ntaub ntawv rau lub xov tooj lub koob yees duab, nws txhawb ceev nws pib - raug rau smartphones lub koob yees duab thiab tshem tawm cov ripple nyhuv tshwm sim los ntawm ambient teeb pom kev zoo strobes.
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.
