A data interface with overvoltage protection circuitry includes a bus interface and power rectification stage configured to provide supply and return voltages for the data interface and overvoltage protection circuitry, a first power level overvoltage protection circuit, a second power level overvoltage protection circuit, a DALI endpoint power output port, a power supply for a DALI endpoint device drawing current from the power output port, a receiver configured to receive signals on the DALI bus, and, a transmitter configured to send signals on the DALI bus.

Data interface with overvoltage protection for two-way digital control bus system

A power handling system of a digitally addressable lighting interface (DALI) system controls switches connected with a bus of the DALI system that powers lower power light sources. A power supply circuit receives energy conducted on the bus to the lower power light sources and conducts at least part of the energy to a capacitor. Electric energy is stored in the capacitor until the capacitor stores at least a designated threshold of input voltage of a controller. The capacitor powers the controller to close one or more switches using at least some of the stored electric energy.

Power handling system and method

A fluorescent lighting device includes a ballast and a tube. An amalgam is located within the tube. A resistive heater is operatively coupled with the ballast, to receive electrical power from the ballast while the fluorescent lighting device is in an OFF state. The resistive heater is mounted near the amalgam to transfer heat to the amalgam while the fluorescent lighting device is in the OFF state.
