Abstract
A lighting device controller includes a power supply, a switch, a battery, and a status indicator. The switch can be set to either an AC only or battery backup position, indicating whether the lighting device controller provides a battery backup signal to the lighted sign. When set to the battery backup position, the lighting device controller powers the lighted sign and charges the battery. If AC power is lost while in the battery backup mode, backup power is supplied from the battery to the lighted sign. The status indicators behavior changes as a function of the switch position to indicate whether AC power is present in the AC only mode or in the battery backup mode indicates one color for AC present and battery charging, and provides a second color to indicate battery not present or low.
