Abstract
An emergency wayfinding device including a lighting controller, a lighting circuit, and a light emitting element. The emergency wayfinding device may draw electricity through a twist-lock plug or draw it from a power source such a battery or a photovoltaic cell. The wide-area communications device is in electrical communication with a connected lighting controller and is configured to send and receive signals or messages to and from a central broadcasting device as well as other emergency wayfinding devices. The lighting controller is configured to change a property of light emitted from a light emitting element based upon signals or messages received by a wide-area communications device. The wide-area communications device communicates a received message or signal to the lighting controller and the lighting controller generates a lighting control signal or message. The lighting controller communicates the generated lighting control signal or message to the lighting circuit, and in response, the lighting circuit changes a property of the light emitted from the light emitting element based upon the lighting control signal or message.
