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. The identifier compares a signal intensity of each of the frequency components with one or more signal intensities of other frequency components. When a signal intensity of a first frequency component is greater than signal intensities of one or more second frequency components located in the vicinity of the first frequency component by an extent exceeding a threshold range, the identifier determines the first frequency component as the noise component.

Sensor device and lighting device

Light control communication system includes first conversion unit, controller-side communication unit, device-side communication unit, and second conversion unit. First conversion unit converts an input signal in conformity with a first protocol used for controlling lighting device into a communication signal in conformity with a second protocol. Controller-side communication unit transmits the communication signal to device-side communication unit. Second conversion unit converts the communication signal into a control signal in conformity with the first protocol output to lighting device. First conversion unit extracts only data of a predetermined channel from channels of the input signal and converts the extracted data into the communication signal. Second conversion unit interpolates predetermined data in the communication signal to convert into the control signal.

Light control communication system, light control communication method and program

A luminaire includes a radio wave sensor and a luminaire body. The luminaire body includes a first plate to be attached to a building surface and a second plate facing each other forming an internal space. The luminaire body holds the radio wave sensor between the first plate and the second plate. The radio wave sensor includes an antenna for transmitting and receiving the radio waves. The luminaire body includes an opening and a limiter. The opening is formed in the second plate to allow radio waves transmitted from the antenna to exit to an outside of the luminaire body. The limiter is provided between the antenna and the opening to limit a radiation area of the radio waves transmitted from the antenna.

Luminaire

A radio wave sensor includes a transmitting antenna configured to radiate radio waves, a receiving antenna configured to receive incoming radio waves, and a housing that is composed of dielectric material and faces the transmitting and receiving antennas. The housing has a first part that faces the transmitting antenna, a second part that faces the receiving antenna, and a third part between the first and second parts. In a facing direction in which a bottom board of the housing faces the transmitting and receiving antennas, respective thickness of the first and second parts is thicker than thickness of the third part.

Radio wave sensor and luminaire

A lighting system includes: a radio remote controller including a command transmitter which transmits a command; a relay including a relay receiver which receives the command and a relay transmitter which wirelessly transmits the command received by the relay receiver; and a lighting device including a command receiver, a storage, and a control circuit which (a) controls a light source according to the instruction included in a received command and stores a command number included in the received command in the storage, if the command number included in the received command does not match a command number stored in the storage, and (b) discards the received command if the command number included in the received command matches the command number stored in the storage.

Lighting system, lighting device, and method of communication in lighting system

A lighting fixture includes a transceiver, a receiver, a storage, and a controller. The transceiver receives a radio command from a radio remote controller for operating the lighting fixture. The receiver receives an infrared command from an infrared remote controller for operating the lighting fixture. The storage stores identification information of the radio remote controller. The controller, if the identification information is stored in the storage, accepts a radio command that includes identification information same as the identification information stored in the storage, among radio commands received by the transceiver, and ignores the infrared command received by the receiver, and if no identification information is stored in the storage, accepts the infrared command received by the receiver.

Lighting fixture, lighting system, and method performed by the lighting fixture

A pairing method for causing lighting devices to store identification information of a radio remote controller serving as a master device is provided. The method includes: transmitting a pairing command including the identification information of the radio remote controller repeatedly on a temporary basis by the radio remote controller; determining, for each of the lighting devices, whether or not the lighting device is in an initial state in which identification information of a master device is not stored in the lighting device, at power on; storing the identification information included in the pairing command, if the paring command is received when it is determined that the lighting device is in the initial state in the determining; and causing the lighting device in which the identification information of the master device is stored to operate according to a radio command including the identification information of the master device.

Pairing method, lighting device, and lighting system

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.

Lighting system

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.

Sensor device for reducing erroneous activation of a light source

This lighting apparatus includes three or more LEDs arranged in a row. Each of the LEDs emits light of a color different from that of an LED adjacent to itself, and the LEDs include an LED having a relatively wide light distribution angle and others of the three or more LEDs each having a relatively narrow light distribution angle. The one LED is arranged in an inner portion in the row of the other LEDs. In this configuration, light emitted from the one LED is mixed well with lights emitted from the respective other LEDs adjacent to the one LED, and thus, color unevenness of illuminating light can be reduced.

Lighting apparatus

A lighting control system includes lighting devices arranged along a road for a moving body. Each lighting device includes a sensor that detects a moving body approaching the lighting device, a light source that emits light, a sensor that detects the moving body, a control unit connected to the sensor and the light source, and a communication unit. The sensor of the one of the lighting devices located in at least at one outermost position of the lighting devices has a higher detection frequency than the sensors of the other lighting devices.
