Infrared LED/Ambient Light Sensor

The Ambient Light Sensor (ALS) products from Luckylight provide measurements of ambient light intensity which match the human eye’s response to light under a variety of lighting conditions.

Each device has a specific operating range of performance, from very low light up to bright sunlight. High sensitivity coupled with wide dynamic range make these ALS products ideal for operation behind dark inked glass. They enable consumer electronics device manufacturers to implement display dimming and brightness control functions, helping to reduce power consumption and extend battery run-time.
