A sensor device includes a radio wave sensor and a signal processor. The signal processor includes an identifier and a noise remover configured to remove, from a second sensor signal, at least one frequency component determined as a noise component by the identifier.

A lighting apparatus includes a plurality of LEDs arranged in a row on an elongated wiring board; and a lens covering all the LEDs and controlling distribution of light emitted from each LED. An optical axis of the light emitted from each LED is orthogonal to the wiring board. The lens has a light emitting surface that controls distribution of the light emitted from each LED. When the light emitting surface is divided into at least three regions, the lens performs light distribution such that light radiated from a region is distributed in a direction tilted with respect to the optical axis of the light emitted from the LED. Thus, asymmetric distribution of light is achieved when the optical axis of the light from the LED is the axis of symmetry, and further, the luminous flux in the direction tilted with respect to the optical axis is increased most.

Therefore, it is possible to effectively illuminate a cabin of an aircraft with less lighting apparatuses as compared to conventional lighting apparatuses which are provided along both sides of the aisle. Moreover, since the number of the lighting apparatuses can be reduced, it is possible to improve fuel efficiency of the aircraft by reducing the total weight of the aircraft.
