An aircraft emergency lighting system is disclosed. This emergency lighting system may include interior emergency lighting, interior ambient light sensors, exterior emergency lighting, and exterior ambient light sensors. The interior emergency lighting, the exterior emergency lighting, or both, may be controlled based upon an input of the interior ambient light condition (e.g., using an output from at least one of the interior ambient light sensors) and based upon an input from at least one of the exterior ambient light sensors.

An integrated guidance system of a vehicle, may include a sensor configured to collect vehicle information of the vehicle; a lamp configured to selectively light a point including a door or a seat in an internal space of the vehicle when emitting the light; a projector configured to display guidance information on a projection surface of the internal space of the vehicle; and a controller connected to the sensor, the lamp and the projector and configured to control whether the lamp emits the light and the lighting point according to the vehicle information, generate the guidance information for guiding a passenger of the vehicle, and provide the guidance information to the projector, and a method for controlling the same.

A vehicle roof lighting unit for illuminating an interior compartment of the vehicle. The unit includes one or more direct light emitting elements, wherein each of the direct light emitting elements are configured to illuminate a portion of the interior compartment, and wherein the one or more direct light emitting elements are located on the exterior of the vehicle roof lighting unit. The unit also includes one or more indirect light emitting elements for providing general lighting for the entire interior compartment, wherein the one or more indirect light emitting elements are concealed from view and the light from the one or more indirect light emitting elements reflects off a curved reflective structure. The unit further includes a control panel, wherein the control panel is located on the exterior of the vehicle roof lighting unit.
