Patent attributes
A plurality of networked lighting devices are deployed in a parking garage. The lighting devices each have a display, a controllable general illumination light source, and an occupancy sensor. When a user enters the parking garage in a vehicle, the display of lighting devices outputs directional arrows and communicates with other lighting devices to direct the user to a vacant parking space (e.g., displays green). In response to detecting that the vehicle has parked in a parking space, the display output is adjusted (e.g., displays red) and the general illumination light source is changed to a different lighting state. Hence, when the user pulls into the parking space, illumination lighting is activated to a brighter setting. The illumination lighting is adjusted to the brighter setting as the user approaches other lighting devices, for example, when approaching an elevator or later re-approaches the vehicle to provide a feeling of safety.
