LCD displays with LED backlights can have their brightness adjusted using ambient light sensor (ALS) ICs. This brightness is determined by ambient light availability, display visibility brightness, and energy efficiency.
The Ambient Light Sensor (ALS) products from ams offer ambient light intensity measurements that correspond to the eye’s reaction to light in a range of lighting conditions.
Each gadget operates within a particular performance range, from very low light to direct sThe lux is the accepted international unit for measuring ambient light illuminance.
An ambient light sensor’s performance ranges from less than 50 lux in low light to more than 10,000 lux at midday.
Phototransistors, photodiodes, and photonic integrated circuits which combine a photodetector and an amplifier in a single component are the three most prevalent forms of ambient light sensors.
The global ambient light sensor IC market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Innovative ambient light sensors (ALS) from ST provide precise data on ambient light, such as the Illuminance (lux) level, the color temperature, or the frequency of light flickering, in an optimized package size.
In addition to the new VD6283TX, a tiny full-color sensor with sophisticated light flicker frequency extraction, ST also offers the VL6180X, which integrates ambient light sensing (ALS), a Time-of-Flight (ToF) range sensor, and an IR emitter in a single module.
The Silicon Labs Si1133 Ambient Light Sensor ICs feature a digital signal processor, a high-sensitivity array of UV, visible, and infrared photodiodes, and twin 23-bit analog-to-digital converters.
The 10-lead 2x2mm DFN packaging of the Silicon Labs Si1133 allows it to function between 1.62 and 3.6V throughout a temperature range of -40 to +85°C.
