STLUXTM turns on your innovative ideas

STLUXTM digital controllers are the world’s first programmable controllers specifically optimized for lighting applications.

The innovative SMED (state machine, event-driven) digital technology and the integrated microcontroller make STLUXTM easily programmable and versatile. It can be configured with application-specific algorithms to optimize the overall system efficiency, enabling high-performance and cost-effective lighting design.

SMED is a hardware state machine triggered by internal or external events. In power-supply applications, for example, a SMED can close the regulation loop and automatically switch off the circuit when it detects an overcurrent or a short circuit, so protecting the circuit. Since SMEDs are embedded, they guarantee an event reaction time shorter than that provided by standard interrupt-driven microprocessors.

The first member of the family, STLUX385A, also integrates DALI (digital addressable lighting interface) for remote control and monitoring.
