Description

Lighting device

The present invention relates to a lighting device using an element that emits light with DC power, and more particularly to a communication device attached to the lighting device and its communication setting method.

Lighting devices using elements that emit light by supplying direct-current power, such as light-emitting diodes and laser diodes, to the light source have a longer life, smaller size, and lower power consumption than illumination light sources such as incandescent bulbs and fluorescent lamps. The amount of use is increasing. Light-emitting diodes do not require extra heat, have a fast response speed, and can be controlled to control blinking and light emission modulation by controlling the power supply. Suitable for Therefore, it has been proposed to use the light source of illumination light as a signal source as it is (see, for example, Patent Document 1).

In addition, it has been proposed to modulate the visible light for illumination for communication and separately modulate the infrared LED (Light Emitting Diode) when the visible light is extinguished (for example, patent document). 2 and 3). Patent Document 2 proposes supplying power to the visible LED of the illumination unit when the illumination is turned on and supplying power to the infrared LED when the illumination is turned off.

In addition, a communication data transmission unit and a light receiving element are provided in the visible light LED illuminating unit, and an optical wireless LAN can be configured between a slave unit having an infrared light transmission unit and a light receiving element connected to a personal computer or the like. It has been proposed (see, for example, Patent Document 4).

When communicating with the optical wireless LAN communication device on the master unit provided in the conventional LED lighting device and the optical wireless LAN slave device communication device on the slave unit provided in an external device separated from the master wireless device, Stable communication is difficult and communication setting is difficult in the boundary region where communication is possible when there is an obstacle or when it is predicted from the emission intensity and the attenuation of space. Stable communication and communication settings are difficult when there are obstacles because the light is straight and has less wraparound, so it is difficult to communicate with the communication device of the other party beyond the obstacle as seen from the light source. This is because of this.

In addition, stable communication and communication settings in the boundary area are difficult because the amount of light attenuation is relatively large, so what could be communicated due to slight changes in environmental conditions, etc. changed to impossible or vice versa. This is because there are changes. For example, when an optical wireless LAN is installed in an LED lighting device in a room of a large area such as a factory or an office, the range in which communication is possible between a parent device installed in one lighting and a plurality of child devices is as follows. It fluctuates depending on a plurality of conditions such as the installation height of the apparatus, presence / absence of facilities (partitions, racks, desks, equipment, etc.) that interfere with communication, and movement of the arrangement. Accordingly, the range that can be communicated with the optical wireless LAN varies depending on a slight change in the room interior or a change in arrangement, etc., and each time the optical wireless LAN communication device side of the slave unit is different from the base unit side (LED lighting device) Communication settings with the other side.

In addition, since the reach distance between the parent and child of the optical wireless LAN communication device is generally shorter than that of the wireless LAN communication device using radio waves, the range covered by the parent device of each optical wireless LAN communication device Is narrow and it is easy to create a boundary area in the room. In addition, when a room is illuminated with a plurality of lighting devices, the plurality of lighting devices may need to be provided with the function of the master unit of the optical wireless LAN communication device due to the short reach distance between the parent and the child.

For the above reasons, when installing a plurality of lighting devices in a room, which lighting device is provided with the optical wireless LAN communication device depends on the arrangement of the slave side communication device at the time of installation and the experience of the installer / It is determined by the skill, or when the installer has little experience / skill, it is determined by increasing the safety factor so that the number and arrangement of the slave side communication devices have a margin.

However, only the master unit of the optical wireless LAN communication device is installed in these lighting devices. When communication is impossible due to a boundary area or an obstacle, the slave unit side of the external device such as a personal computer is actually installed. The only way to find out where the communication can be done while trying to connect to the base unit every time after changing the arrangement of the surrounding equipment or changing the arrangement of the surrounding equipment is a complicated task, and it takes time and man-hours. It was hanging. In addition, when communication becomes impossible due to movement of an external device, rearrangement of surrounding equipment, and the like, addition of a new external device requires similar work, and complicated work is necessary.

In short, to increase the safety factor is to increase the number of optical wireless LAN communication devices installed in each of a plurality of lighting devices. For example, when the communication distance from the first optical wireless LAN communication device on the parent device side provided in the first LED lighting device to the communication device on the partner child device side is a boundary region, the communication device of the partner Does not set up communication with the first optical wireless LAN communication device, and does not communicate with the second optical wireless LAN communication device provided separately in the second LED lighting device having a shorter communication distance. Stable communication can be performed by setting communication. In this way, it is possible to increase the safety factor of communication by reducing the possibility of communication failure.

In addition, with respect to the installation of the conventional optical wireless LAN base unit provided in the LED lighting device, the placement is fixed based on the placement of the optical wireless LAN communication device on the slave side expected when the LED lighting device is installed. It was decided. Therefore, there is a case where the base unit cannot cope with the change of the arrangement of the optical wireless LAN communication device on the side of the slave unit. In other words, when the arrangement of the optical wireless LAN communication device on the slave unit side is changed, it may become impossible to transmit and receive communication signals using light between the parent and the child. In that case, for example, “Which parent device should be selected from a plurality of existing parent devices for communication setting?”, “A new parent device is connected to an LED lighting device that is not currently installed. It is necessary to judge whether it should be installed.

Conventionally, when a communication signal due to light between the parent and child cannot be received on the side of the slave unit, as described above, search for a good arrangement while moving the slave unit side, or connect the master unit to an LED lighting device closer to the distance. There is no choice but to try installing and setting the function of the master unit, for example, on an external device such as a personal computer connected to the router via a wired LAN or other slave unit that can communicate well There has been no choice but to use an optical wireless LAN communication device and an external device connected thereto. Also, other external devices are required for processing such as transmitting optical signals from the parent device side for inspection to the optical wireless LAN communication device on the child device side, which is unable to transmit / receive between the parent and child. Therefore, it is a complicated process, requiring a lot of man-hours and time, and difficult to judge.

As for the communication setting of the optical wireless LAN communication device on the slave unit side, for example, when the distance to the master unit is the distance of the boundary area of communication, or a partial obstacle between the master unit If there is a problem with communication between the parent and child, etc., should the communication settings with the current parent device be continued as it is, or should the communication settings with other parent devices be changed? "?" Is also complicated with respect to the optical wireless LAN communication device on the side of the slave unit in which the problem has occurred, using the optical wireless LAN communication device on the other side of the slave unit that can communicate satisfactorily. It was necessary to make a judgment in the processing process, and it took a lot of man-hours and time.

In other words, when there is a problem in communication between the optical wireless LAN communication device and the parent and child, the optical wireless LAN communication device on one slave unit actually confirms the communication connection status with the parent device on site. In other words, it is necessary to use other slave units that cannot communicate with each other and cannot be set to adapt to them. Therefore, it is not easy to change the master unit of the optical wireless LAN to a master unit of another LED lighting device or to newly install a master unit in another LED lighting device.

Therefore, for example, when installing a master unit in a business office having a large area and having a plurality of LED lighting devices, a master unit of a wireless LAN is installed for each range narrower than the assumed wireless LAN communication range of each master unit. The equipment cost and construction cost of the main unit have increased. Further, even if an area in which a radio signal from the parent device cannot be received due to a change in location or the like, the parent device cannot be easily expanded / relocated.

It is also conceivable to use PLC (Power Line Communication: high-speed power line communication) instead of the optical wireless LAN communication device. Regarding the use of PLC, there is a possibility of using a power supply line from a switchboard or the like to LED lighting. However, since LAN wiring is also possible when wiring the power source in the wall or the ceiling, it may be selected when the power is already wired in the wall or the ceiling. However, when used between LAN base units and slave units, PLC is vulnerable to noise from power supply equipment and leakage of electromagnetic waves, and the communication speed is particularly low for tachometer wiring, which is much slower than the communication speed on the desk. Have a problem. Therefore, even if the PLC is used instead of the optical wireless LAN communication between the main unit on the LED illumination side and the slave unit on the external device side, there is little possibility of obtaining a sufficient communication speed and convenience. There are fewer effects and more problems.

Therefore, in order to solve the above-described problems, the present invention is not only for newly installing an optical wireless LAN, but also for changing the master unit of the optical wireless LAN provided in the lighting device, changing the arrangement of the slave units, and the optical wireless LAN. Provide lighting device and communication setting method that can respond to change with only one slave unit that is set to communicate with the master unit in response to the situation and changes in the field even when there is an obstacle arrangement change with respect to For the purpose.

In order to solve the above problems, one embodiment of a lighting device according to the present invention includes a lighting unit using an element that emits light when DC power is supplied, and a LAN router on the external communication line network side. A LAN line network side connection unit connected to the wireless LAN, a wireless LAN base unit side communication unit capable of communicating with a wireless LAN slave unit side communication device provided in an external device separated from the lighting device, and optical wireless of the external device An optical wireless LAN base unit communication unit capable of communicating with the LAN slave unit side communication device and an external device that communicates with the wireless LAN slave unit side communication device provided in the external device by the wireless LAN base unit side communication unit. When the optical signal is transmitted from the optical wireless LAN slave unit side communication device and the optical wireless LAN base unit side communication unit can receive the optical signal from the optical wireless LAN slave unit side communication device, Connect the wireless LAN base unit side communication unit Having at least a control unit for switching on al the optical wireless LAN base-side communication unit.

<First Embodiment>
1st Embodiment of the illuminating device of this invention is a case where the removable communication part of an illuminating device communicates with the external apparatus in a building by radio | wireless. The outside of the external device is the outside that is separated from the lighting device and is the inside for the building. Hereinafter, the lighting apparatus according to the first embodiment will be described with reference to FIGS. 1 to 5 and further using FIG. 13 of the prior art for comparison.

(Power supply related)
The lighting devices 501 to 504 of the first embodiment are installed inside the building 100 and on the ceiling or the upper part of the wall surface. The building 100 may be a small building such as a house or an office, but is preferably a factory or office having a large area and a large number of lighting devices 501 to 504 installed therein. The building 100 is supplied with power from the commercial power line 200 through the pole transformer 210 and the like to the distribution board 230 in the room. Electric power is supplied from the distribution board 230 to each of the lighting devices 501 to 504 in the building 100 and each of the external devices 111 to 118 in the building 100 with AC 100 V or AC 200 V. Power supply power to each of the lighting devices 501 to 504 is supplied via the DC power supply devices 241 to 244.

The lighting devices 501 to 504 are connected to DC power supply devices 241 to 244. The DC power supply devices 241 to 244 are disposed on the ceiling or the like of the building 100 and supply power suitable for lighting the lighting units 510 in the lighting devices 501 to 504 from power such as AC100V or AC200V. In the case where the illumination unit 510 is an LED lighting device, the DC power supply devices 241 to 244 convert AC 100 V of commercial power into a DC voltage value and current value suitable for lighting the LED lighting device and supply them.

As described above, each illumination unit 510 for each illumination device 501 to 504 uses an LED element that emits light when DC power is supplied from the DC power supply device 241 to 244. Since the LED element is driven by direct current, noise can be prevented.

AC-DC converters (AC-DC converters) such as DC power supply devices 241 to 244 include (A) a method using a transformer and a rectifying / smoothing circuit, (B) a method using a series regulator, and (C) a switching power supply. Although there is a method to use, (A) and (B) are preferable in that high frequency noise such as switching is not basically generated. However, even the switching power supply system of (C) can be used if it is an AC-DC converter in which noise components affecting communication are sufficiently suppressed.

Further, as the DC power supply devices 241 to 244, a constant current circuit capable of efficiently lighting the LED is preferable because heat loss can be suppressed and influence due to voltage variation and temperature change can be reduced. In particular, in the case of high luminance (high output), a constant current circuit is essential. In FIG. 1, the DC power supply devices 241 to 244 are individually provided for the respective lighting devices 501 to 504. However, the DC power supply devices 241 to 244 may be combined into one or two, etc. The devices 501 to 504 may be incorporated.

When only the lighting devices 501 to 504 are provided with ON / OFF switches that are turned on / off, the optical wireless LAN base unit side communication unit 992 and the wireless LAN base unit side communication unit are connected from the DC power supply units 241 to 244. If the power supply path 552 to 1012 is made independent of the power supply path 551 from the DC power supply devices 241 to 244 to the illumination unit 510, the power supply to the communication devices 601 to 604 can be secured even when the light is turned off. .

In the case where an ON / OFF switch for lighting / extinguishing is provided in the middle of the wiring in the wall body separately from the main body of the lighting devices 501 to 504, first, the first connection to the lighting devices 501 to 504 is performed. 1 is connected to the DC power supply devices 241 to 244 from the distribution board 230 via the wall ON / OFF switches, and further from the DC power supply devices 241 to 244 to the DC power of the lighting devices 501 to 504. The first supply unit 541 is connected by a first wiring member 551 that conductively connects the first supply unit 541 and the illumination unit 510.

On the other hand, the power supply path to the general-purpose terminals 531 to 533 is an independent line in which the wiring from the distribution board 230 to the DC power supply devices 241 to 244 is connected at least to the power supply source side of the wall ON / OFF switch. And the second supply unit 542 and the optical wireless communication from the DC power supply devices 241 to 244 via the optical wireless LAN base unit side communication unit 992 and the DC power second supply unit 542 of the wireless LAN base unit side communication unit 1012. The LAN base unit side communication unit 992 and the wireless LAN base unit side communication unit 1012 are connected by a second wiring member 552 that is conductively connected. As a result, the wireless LAN base unit side communication unit 1012 and the optical wireless LAN base unit side communication unit 992 have power supply wiring connected to the source side of the power supply rather than the ON / OFF switch of the illumination unit 510.
