An emergency converter device for lighting applications provides a supply current to a load device such as a lighting module. The emergency converter device has a printed circuit board arranged within a housing. A control circuit such as a microcontroller and a non-volatile memory for storing log data are arranged on the printed circuit board. An interface is configured to connect mechanically and electrically at least one of a status indicator light a test switch or a duration link select switch. The interface has a first connecting element and a second connecting element. The emergency converter device has a connecting means for connecting a data output terminal (USART_TX) and a data input terminal (USART_RX) of the control circuit to the exterior of the housing.

Reading data from a log data storage in an emergency lighting converter

The invention relates to a driver () for emergency lighting means (), comprising output terminals (-) for electrically supplying at least one emergency lighting means (), and a test switch () for starting a test routine controlled by a controller () of the driver (), wherein the driver () is settable to a commissioning mode if the test switch () is activated according to a predefined operation pattern defined by time durations and/or repetition criteria of the operation pattern.

Driver for emergency lighting means

An emergency converter device provides an interface for selecting an operation parameter for an emergency operation mode of the emergency converter device. The emergency converter device provides a supply current Ito a load device, in particular to a lighting module including on or more light emitting diodes. The emergency converter device comprises a control circuit configured to set at least one operating parameter of the emergency converter device, an interface comprising a first terminal and a second terminal for connecting electrically a status indicator light emitting diode, and a detection circuit connected to the control circuit. The detection circuit is configured to detect a polarity of the status indicator light emitting diode connected to the first terminal and the second terminal, and the control circuit selects the at least one operating parameter of the emergency converter device based on the detected polarity.

Duration select switch for an emergency lighting converter

An emergency converter according to the invention is used in lighting applications for operation from an energy storage device in case of mains failure. The converter device comprises a charger circuit configured to charge the energy storage device and a microcontroller circuit configured to control the charger circuit. The driver circuit is preferably implemented in a coupled inductor boost circuit topology. The microcontroller circuit is further configured to control the switch based on a zero crossing of a measured inductor current.
