Osram ams je danas najavio TSL2585, senzor ambijentalnog svjetla sa vlasničkom UV-tehnologijom detekcije svjetla koja detektuje UV-zračenje u prirodnom svjetlu za-ograničene aplikacije za nošenje i druge mobilne aplikacije.
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.
U isto vrijeme, fotodioda TSL2585 usvaja jedinstveni -centralni raspored, što mu omogućava da podrži dizajn uskog okvira, integriše detekciju treperenja izvora svjetlosti i opremljena je sa tri modulatora sa stopom uzorkovanja od većeg do 14 kHz. Pružajući informacije o osvjetljenju i ambijentalnom svjetlu kameri telefona, podržava brzu automatsku{3}}ekspoziciju za kamere pametnog telefona i eliminiše efekat mreškanja uzrokovan strobovima ambijentalnog osvjetljenja.
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.
