  • Publication number: 20140042915
    Abstract: Plural luminaires are installed in a lighting space surrounded by a wall part. A sensor equipment detects existence or nonexistence of a person in the lighting space. If existence of a person in the lighting space is detected, the sensor equipment detects a direction of the person. The sensor equipment detects a distance between the wall part positioned in front of the direction of the person and the person. A lighting control unit selectively switches between a first control for performing lighting control of the luminaires to illuminate the wall part positioned in front of the direction of the person if the detected distance is a specified distance or less, and a second control for performing lighting control of the luminaires to reduce brightness at a place as the place becomes farther from a position of the person if the detected distance is larger than the specified distance.

  • Patent number: 8638036
    Abstract: A wireless light sensor, being part of a lighting system, has a sensor element generating a light measuring signal, a microcontroller coupled to the sensor element, and a radio communication device coupled to the microcontroller. The microcontroller has an active mode and a sleeping mode. The light sensor further has a wake-up circuit which determines a rate of change of the light measuring signal, when the microcontroller is in the sleeping mode. The wake-up circuit brings the microcontroller from the sleeping mode into the active mode, when the rate of change of the light measuring signal exceeds a predetermined threshold.

  • Patent number: 8587415
    Abstract: A wall switch motion sensor detects motion using a lens and an infrared detector, and in response performs a function (for example, turns on a light). The motion sensor is also adapted to respond to IR remote control signals of the type customarily used to control electronic consumer devices in the home. In one example, a user uses an ordinary remote control device to transmit a sequence of IR control signals and dead times toward the motion sensor. The detector in the motion sensor detects each IR control signal as an increased amount of IR energy, whereas it detects a dead time as a period of less IR energy. If the periodicity of the sequence is appropriate, then the wall switch motion sensor determines that the sequence is an instruction. In one example, the instruction is to turn on/off the light controlled by the wall switch motion sensor.

  • Publication number: 20130278423
    Abstract: A detecting device includes at least one transmitter and plural receivers. After the at least one transmitter emits plural incident light beams to a detection zone, plural reflected light beams reflected from the detection zone are received by the plural receivers. If no object is moved within the detection zone, the plural reflected light beams strike a first part of the plural receivers, so that the plural receivers are in an initial reception configuration. If an object is moved within the detection zone, the plural reflected light beams are disturbed by the object and deflected to a second part of the plural receivers, so that the plural receivers are in a disturbed reception configuration. According to the reception configuration change, a moving direction of the object within the detection zone is determined. Consequently, the detecting range is largely enhanced, and the cost is reduced.

The camera may capture an image having a configuration code associated with the network and the CPU may analyze the image to determine the existence of the configuration code. The CPU may then configure the network interface to connect the luminaire to the network so that the luminaire may be operated or monitored through the network.

  • Patent number: 8154207
    Abstract: A control unit determines whether a vehicle has entered an area under a covering object that covers the upper side of the vehicle. In the case where the control unit determines that the vehicle has entered the area under the covering object, the control unit turns on light apparatus when both of a measurement of an upper light intensity, which is measured with an upper light intensity sensor, and a measurement of a front light intensity, which is measured with a front light intensity sensor, require turning on of the light apparatus.

  • Publication number: 20110221350
    Abstract: A lighting system includes a master that controls a plurality of light fixtures via wireless RF communications. An ambient light sensor in the master is used to monitor total ambient light and to prevent excessive illumination. In an auto-calibration process, the master makes ambient light measurements A, B and C when the light fixtures are illuminating an area at a minimum setting, at a maximum setting, and at an intermediate setting, respectively. A first threshold is set to be approximately (B?A). A second threshold is set to be slightly larger than (B?A)+(B?C). In normal system operation, total ambient light measurements are taken and compared to the two thresholds. In one example, if detected brightness is lower than the first threshold then the system is set at its maximum illumination setting, whereas if detected brightness is greater than the second threshold then the system is set at its intermediate illumination setting.

  • Patent number: 7965050
    Abstract: In an arrangement of lighting devices (10), a remote control device (30) and a central control device (20), a particular lighting device to be controlled by means of the remote control device may be selected by a user transmitting a selecting command (42, 43). When the central control device receives the selecting command (44), it carries out a selection sequence (45) during which it controls the lighting devices in one or the other sequence so as to have their output change temporarily (45, 46, 47). If the remote control device, which is directed to the particular lighting device (41), senses such an output change (50), it transmits data representing such an event (51) to the central control device. When the central control device receives such event data (52), it determines the particular lighting device as that to which the remote control device is directed (53) for subsequent control (54) of this particular lighting device.

    Abstract: A flat display device is adapted for human eye observation with or without applying a NVIS (Night Vision Imaging System). The flat display device includes a display panel, a backlight module and a backlight driving unit. The backlight module includes multiple red light LEDs (Light Emitting Diodes), green light LEDs and blue light LEDs that form together a light source array, so as to generate a backlight by mixing and projecting the red light, green light and blue light to the display panel. The backlight driving unit is electrically connected with the light source array and used to drive and control the red light LEDs, green light LEDs and blue light LEDs. At a night-vision mode, the backlight driving unit may, upon actuation of a actuating signal, adjust or disable the red light LED by for example decreasing or turning off the driving electricity sent to the red light LED, thereby achieving the requirements for nigh vision purposes.
