Digitally addressable lighting interface (DALI) compatible communication device and corresponding method for sending messages through the communication bus.

摘要

A DALI-compatible communication device for transmitting a message through a communication bus including two communication lines provides a switch connected between the two communication lines and a logical communication level for the communication bus. A controller configured to control the switch, an energy storage device connected in series with the switch and configured to store electrical energy flowing from the bus via the switch, and the energy storage device. It has a bypass circuit configured to bypass the energy storage device when the voltage exceeds a predetermined voltage threshold.
