US 2020/0028378 A1 · EMERGENCY LIGHTING CONVERTER

Abstract

The invention is in the field of emergency lighting devices and power supply of emergency lighting devices. A LED converter for an emergency lighting unit comprises a LED driver for supplying a current to a LED lighting device, an energy storage interface for connecting an energy storage device, a charging circuit for charging the energy storage, and a control circuit. The energy storage interface is configured to connect at least two different types of energy storage devices. The charging circuit sets at least one energy storage management parameter according to the type of energy storage device connected by the energy storage interface. The control circuit determines the type of energy storage device connected by the energy storage interface and controls the charging circuit to set the energy storage management parameter according to the determined type of energy storage device.
