ams OSRAM OSIRE® E3731i RGB LEDs
Specifically designed for automotive interior applications
The ams OSRAM OSIRE® E3731i RGB LED is especially designed for automotive interior applications requesting high dynamic RGB lighting scenarios.
The E3731i is an intelligent RGB device, incorporating besides R/G/B LEDs an IC from ams OSRAM. This embedded IC integrates the drivers for the three R/G/B LEDs.
The embedded IC includes the optical measurement data of the three R/G/B LEDs as well. An external micro controller can address and control each device in a daisy chain architecture via an open system protocol. The open protocol allows the micro controller to read back these data and to run any color algorithm. It also allows to read back a temperature value to optimize this color algorithm.
