1. An emergency battery converter system, comprising:
- an emergency battery pack comprising;
a storage device that stores power; and
a step-up converter that converts a direct current (DC) output voltage of the storage device to a stepped-up DC output voltage that corresponds to a rectified voltage potential of a standard alternating current (AC) line voltage;
a lighting driver that is adapted for an input of the standard AC line voltage, the lighting driver comprising;
a rectifier circuit coupled to an output of the step-up converter to receive the stepped-up DC output voltage from the step-up converter as the input and responsively output a DC voltage;
a step-down converter coupled to an output of the rectifier circuit, wherein the step-down converter converts the DC output voltage of the rectifier circuit to a stepped-down DC output voltage; and
a regulator circuit coupled to the step-down converter to regulate the stepped-down DC output voltage to a regulated voltage; and
an emergency luminaire that receives the regulated voltage.

Abstract
An emergency battery converter system provides a low-cost emergency battery converter and lighting system. The battery converter system includes an emergency battery pack, a lighting driver, and an emergency luminaire. In certain example embodiments, the emergency battery pack is coupled to a power delivery system and is charged by the power delivery system. The lighting driver receives power from the battery pack and steps up and regulates the power to be suitable for use by the emergency luminaire. In certain example embodiments, the emergency luminaire illuminates an egress area.
