Osram ams ha annunciato oggi il TSL2585, un sensore di luce ambientale con tecnologia proprietaria di rilevamento della luce UV-che rileva i raggi UV-una radiazione nella luce naturale per dispositivi indossabili e altre applicazioni mobili limitate nello spazio-.
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.
Allo stesso tempo, il fotodiodo del TSL2585 adotta un'esclusiva disposizione fuori-centro, che gli consente di supportare un design a cornice stretta, integra il rilevamento dello sfarfallio della sorgente luminosa ed è dotato di tre modulatori con una frequenza di campionamento superiore a 14 kHz. Fornendo informazioni sull'illuminazione e sullo stroboscopio della luce ambientale alla fotocamera del telefono, supporta l'esposizione{3}}automatica rapida per le fotocamere degli smartphone ed elimina l'effetto a catena causato dai flash dell'illuminazione ambientale.
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.
