The world's leading optical solution vendor Amy Si Luram announced that a ambient light sensor using proprietary UV-A light detection technology - TSL2585. Amy Si Lurang's TSL2585 corresponds to the UV channel to detectThe UV-A radiation in the light will remind the user when UV-A is radiated excess. This sensor is extremely compact, so it is very suitable for space-limited wearable applications and other mobile applications.

Although the Earth atmosphere can block the UV-C portion of the sun, UV-A and UV-B radiation can reach the surface of the earth. The UV-A radiation accounts for about 90% of the ultraviolet components that arrive in the surface of the Earth, and can penetrate into the skin of the skin, and in some cases, it will have a serious impact on health, such as weakening connective tissue, accelerate skin aging, and increase Skin cancer chances, etc. By using Ai Mes Osram's new ambient light sensor, when the UV-A radiation value in the environment is too high, the smart watch user can immediately receive a warning.

Barry Guo, Amiis Osram, said: "The TSL2585 is short, the sensitivity is high, even if it is placed under the low transmittance material and the OLED screen, the ambient light can be reliably detected. The small size package and design are greatly improved. The manufacturer's industrial design freedom. "This ambient light sensor adopts the Advanced interference filter of Amiis Osram, which can be accurately deposited on each photodiode pixel to create a 315 nm-400 nm UV-A channel, Personal response to the visual channel and IR channel. They provide the necessary information for indoor and outdoor identification, UV index calculations, and ambient illumination detection. In addition, the photodiode of the TSL2585 uses a unique bias center to support the narrow border design.

The TSL2585 integrates the flash detection function and equipped with three modulators up to 14kHz. By providing illuminance and ambient optical flash information to the mobile phone camera, it supports the fast-automatic exposure of the smartphone camera and eliminates the corrugated effect of the environment lighting.

It uses super flat packages, compact dimensions, only 2.0 mm x 1.0 mm x 0.35 mm, which is suitable for space-saving system design, which helps manufacturers designed extremely compact equipment. The sensor's operating voltage is 1.8V, and the current at not working is only 0.7μA.

Since the integral time is extremely short, the sensor can reliably detect the ambient light even if it is installed under the OLED screen of the smart watch.
