摘要： An light source control unit controls the flashing of a light source and the light amount of a light source according to information to be transmitted. Thus, light, which is modulated according to the information to be transmitted, is emitted from the light source. The light emitted from the light source is made to enter an optical fiber to pass therethrough and enter a light-scattering body which scatters and radiates the modulated light incident from the optical fiber. The scattered light serves as illumination light as it is. Furthermore, if the illumination light is decoded by a decoding unit after being received by a photoreceptor unit of a receiving set, then information carried by the illumination light can be received.

摘要： A communications system implementing high-speed, high-quality communication in an oblong communication range such as mobile communication, and a leaky optical fiber preferably used in such communications system are provided. An optical fiber (2) is a GI-type optical fiber having a core structured such that the refractive index at the center is large, gradually decreasing as it approaches the periphery, and may have scatterers mixed therein. When modulated light enters the optical fiber (2) from a transmitter (1), the modulated light proceeds through the optical fiber (2) while a part of the light leaks from the side thereof. A receiver (3) receives this leaked light, and demodulates it so as to obtain data. Since the optical fiber (2) is a GI type, high-speed, high-quality mobile communication is possible with little waveform deformation.

摘要： In the case of performing communication by using illumination light when the illumination is on, switches are turned on, a signal modulated in an optical modulation part in accordance with information is superposed to a power waveform for the illumination with a power distributor and the illumination 16 is driven in a modulated state. When the illumination is off, the switches are turned off, a switch is turned on and a communication part is driven in a modulated state by the optical modulation part. The communication part can be constituted so as to include an infrared light emitting element part to perform infrared communication when the illumination is off. Consequently communication can be performed not only when the of illumination is on but also when the lighting is kept off. The communication device can be constituted of one element integrating the illumination part and the communication part, so that a compact system can be constituted.

摘要： The illuminating end communication device is equipped with an illuminating light source. An electric power fed to the light source is modulated with a modulating unit responding to transmission data, and the modulated light is sent out as illuminating light. The illumination light is received by the light receiving unit of a terminal end communication device to maintain a downlink. Light emitted from the light emitting unit of the terminal end communication device is received by the light receiving unit of the illuminating end communication device to keep an uplink. Or, illuminating light is modulated on the basis of data when it is reflected, whereby data can be transmitted to the illuminating end communication device. It is preferable that illuminating light is reflected by CCR. A high-quality communication is realized using illuminating light of high power.

摘要： Information received from a wired network terminal on the wall face, or the like, is delivered as a light signal from a light transmitting/receiving section of a light communication unit. A lighting fixture is provided with a light transmitting/receiving section where light is received from the light communication unit in order to acquire information, and a light emitting element emits illumination light modulated according to that information. A terminal can acquire the information by receiving the illumination light at a light transmitting/receiving section. Since communication is performed from the light communication unit to the terminal by irradiating light into the space, a convenient illumination light communication system requiring no communication cable or laying work of optical fibers can be constructed.

摘要： A data communication system capable of controlling the brightness of light sensed by the human eye and quality communication using an illuminative light is provided. A PWM circuit 11 adjusts pulse width in conformity with a light intensity control signal corresponding to a desired light intensity, resulting in a PWM signal. The PWM signal is then transmitted to a phase inverter 12. The phase inverter 12 outputs the PWM signal as is when a data signal to be transmitted is 0, for example, while it inverts the phase of the PWM signal and then outputs the resulting inverted PWM signal when the data signal is 1. A light source driver circuit 13 drives, a light source 14 such as an LED, organic electroluminescence, or the like in conformity with the phase inverted signal to emit light. In a data reception unit 2, an optical sensor 21 converts light emitted from an illuminating device 1 to an electric signal. A phase detection circuit 22 detects the phase of the signal and then outputs a received data signal.
