Dialog adds ambient light, color sensing to SSL control
The development is the result of the recently announced joint venture with Dyna Image in Taiwan (see Dialog, Foxconn, Lite-On to form sensor joint venture).
In recent months, Dialog and Dyna Image have collaborated on a wearable reference design integrating Dyna Image’s all-in-one optical heart rate monitor and MEMS accelerometer sensors with Dialog’s SmartBond DA14580 Bluetooth System-on-Chip (SoC) and sensor fusion software to provide a complete turn-key reference design for wearable fitness bands.
Now the two companies have brought together technologies in solid-state lighting and optical sensing to deliver sensor-based control for LED lighting systems.
Integrating color sensing with Dialog’s tunable-white driver allows lamps to automatically change their color temperature from cold (blue-white) to warm (amber) in tune with the ambient environment. This sensing feature also facilitates automatic compensation for normal variations in color temperature between LED light fixtures. Other applications include the ability to sense color temperature outdoors and replicate it indoors. This creates a natural light experience to help stimulate the human body’s circadian rhythm, which is claimed to produce significant health and wellbeing benefits.
