Abstract: Embodiments of the present disclosure relate to an emergency inverter and an emergency lighting system. The emergency inverter comprises a power detecting module and a dimming signal generating module. The power detecting module is configured to detect an output power of the emergency inverter in an emergency state. The dimming signal generating module is coupled to the power detection module and configured to generate a dimming signal based on the output power of the emergency inverter in the emergency state.

Abstract: A tubular solid state lighting device has a pin safety circuit electrically connected to connection pins of the one end. The pin safety circuit comprises two protection components, of different types. In one set of examples, there is an electrically controlled isolation switch and an electronic switch which functions as a high voltage isolation barrier. The switch provides full galvanic contact separation, whereas the isolation barrier provides current protection if the isolation switch is not functional. In another set of examples, there is a mechanically controlled isolation switch and an electrical or electronic isolation barrier. This provides two levels of protection, but requiring only a single manual operation by the installer of the lighting device. It avoids end-of-life protection circuitry being triggered during the installation of the lighting device.
