Abstract:
A lighting device includes: a receiving circuit which obtains a first image including a subject; a memory which obtains depth information indicating a depth of the subject in the first image; an image processor which converts the first image obtained, into a second image in which the subject in the first image is represented by gradation of a single color, the gradation being different according to the depth indicted by the depth information; a light source; a light modulator which modulates light emitted from the light source, according to the second image; and a light emitter which emits the modulated light.
Abstract:
A lighting control device which controls a lighting device, and includes: a feature quantity calculator which calculates a feature quantity of image content to be reproduced and projected by an image reproducing device; and a lighting controller which controls light emission of the lighting device based on the feature quantity calculated by the feature quantity calculator.
Abstract:
Illumination control system 1 includes illumination apparatuses 10 and control apparatus 20 for controlling them. Each illumination apparatus 10 includes: communication unit 101 that performs wireless communication with control apparatus 20; and controller 102 that receives from control apparatus 20 instruction on operation and causes illumination apparatus 10 to perform the instructed operation. Control apparatus 20 includes: communication unit 201 that establishes connection to perform wireless communication with illumination apparatuses 10; display unit 202 that displays an icon representing target illumination apparatus 10; second controller 203 that transmits instruction on operation of target illumination apparatus 10 to enable a user to visually confirm target illumination apparatus 10; receiver 204 that receives from the user an identifier identifying a group of target illumination apparatus 10 in association with the icon; and registration unit 205 that registers group information indicating the identified group and connection information in association with each other.
Abstract:
A lighting system includes: a first wireless communication unit configured to wirelessly transmit, to a lighting device, a control signal for controlling the lighting device, and to obtain a reception state of a radio wave at one of the first wireless communication unit and the lighting device which is transmitted by the other of the first wireless communication unit and the lighting device; and a determination unit configured to determine whether a person is present in a space in which the lighting device is installed, based on the reception state obtained.
Abstract:
A light fixture includes: a board including a first insertion portion; a plurality of light-emitting elements mounted on a mounting surface of the board; a metal case on which the board is positioned; and an antenna that is housed in the metal case and wirelessly communicates with an external device. The metal case includes a second insertion portion at a position overlapping with the first insertion portion in a plan view of the metal case and the board. The antenna extends through the first insertion portion and the second insertion portion.
Abstract:
A lighting system includes a first luminaire and a second luminaire which are arranged in an illumination area, and a controller. The first luminaire is connected to a first receiver which receives a signal from a transmission tag, and has a first lighting lamp. The second luminaire is connected to a second receiver which receives a signal from the transmission tag, and has a second lighting lamp. The controller turns on the first lighting lamp when the first receiver receives the signal from the transmission tag, then, turns on the second lighting lamp when the second receiver receives the signal from the transmission tag, and notifies that an abnormal situation has occurred when no signal from the transmission tag is received by the first receiver within a predetermined time period from the turning on of the second lighting lamp.
Abstract:
A lighting system includes: a plurality of luminaires; a camera which captures an image of an area illuminated by the plurality of luminaires; a sound collector including at least two microphones; and a controller which determines whether or not a sound collected by the sound collector while the plurality of luminaires are off is a sound from a predetermined direction relative to the sound collector. The controller causes at least one of the plurality of luminaires to emit light of a predetermined brightness and activates the camera when the sound collected by the sound collector is determined to be the sound from the predetermined direction, and does not cause the plurality of luminaires to emit light of the predetermined brightness or activate the camera when the sound collected by the sound collector is determined not to be the sound from the predetermined direction.
Abstract:
A lighting apparatus which is one of a plurality of lighting apparatuses each capable of performing wireless communication with a control device. The lighting apparatus includes: a light emitting unit; a controller which controls turn-on of the light emitting unit; and a communication unit configured to perform wireless communication with the control device to obtain correction time from the control device, the correction time being based on communication delay between the control device and each lighting apparatus. The communication unit further obtains a turn-on instruction for turning on the light emitting unit from the control device, and transmits a response to the turn-on instruction to the control device upon obtainment of the turn-on instruction. The controller turns on the light emitting unit after passage of a time period from when the response is transmitted to the device, the time period being calculated by subtracting communication latency from the correction time.
Abstract:
A luminaire includes: a power circuit that supplies power to a light source; an antenna that at least one of transmits and receives a wireless signal; and a metal housing that contains the antenna and the power circuit, wherein the metal housing has an opening, and the antenna and the opening are arranged to cause a polarization plane of an electric wave most strongly radiated from the antenna and a polarization plane of an electric wave most strongly radiated from the opening to substantially coincide with each other.
Abstract:
A luminaire includes a light source; a storage for storing sound wave data which is predetermined; a microphone that detects sound; a communication circuit that communicates with a master controller; and a controller that performs pairing of the luminaire with the master controller via the communication circuit. The controller obtains sound wave data from the sound detected by the microphone, and performs the pairing when the sound wave data obtained matches the sound wave data stored in the storage.
