Abstract: A sensor device includes a sensor that transmits radio waves of a predetermined frequency and receives reflected waves of the transmitted radio waves. The sensor device detects presence of a moving body based on a difference between a frequency of the transmitted radio waves and a frequency of the reflected waves to activate a light source in accordance with the detection. A processor generates a sensor signal indicating the detection of the sensor. A determination unit determines whether or not the sensor signal has an intensity that is greater than a predetermined threshold. A controller controls activation of the light source when determined that the intensity of the signal is greater than the threshold. The controller restricts activation of the light source when determined that the intensity of the sensor signal is greater than the threshold until a first specified time elapses from the determination.

Abstract: A controller of a lighting fixture is configured to set a light modulation level of an LED to a first light modulation level in a period from a beginning of a night time slot until when a predetermined first time period elapses, regardless of a detection result of a human detecting sensor, and set the light modulation level of the LED to a second light modulation level that is lower than the first light modulation level when the first time period elapses. The controller is configured to set, when the human detecting sensor detects a person in a state where the light modulation level of the LED is set to the second light modulation level, the light modulation level of the LED to the first light modulation level for a predetermined time period.

In a first direction of the two-dimensional array, light sources having a uniform color temperature are successively arranged.

Abstract: 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.

Abstract: A lighting system includes a lighting apparatus provided along one side of an aisle and a specular reflection plate provided along the other side of the aisle to reflect the light emitted from the lighting apparatus toward a region where the lighting apparatus is provided. According to the above configuration, the lighting apparatus can illuminate the region where the lighting apparatus is provided. 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.
