Zusammenfassung:	Emergency lighting devices and methods are disclosed. An emergency lighting device includes a first group of solid state emitters configured to emit light of a first color. The emergency lighting device also includes a second group connected in series to the first group and configured to emit a second color. The groups are configured to receive a normal operation current from an LED driver at the input end of the first group and output the normal operation current at the output end of the second group. In an emergency, the first group receives an emergency operation current from an emergency LED driver at an emergency input and outputs the emergency operation current at an emergency output located.
