Implementing all HW functions for fully SW defined lighting applications, the ISELED/ILaS technology provides manufacturer-calibrated ISELED Smart RGB LEDs for automotive grade RGB or tunable white LED applications. The user simply sends a digital color value to the addressable LEDs, which autonomously performs all color mixing and temperature compensation. Cabled connectivity between lighting boards or directly cabled single ILaS LEDs are supported by the ILaS transceiver, including very power efficient DC/DC conversion from 12V battery voltage as well as communication resilience to board power failures. Synchronized streaming of lighting information from a central ECU is supported via software free Ethernet bridges.
