図１および図２は、本発明の一実施例における、可視光通信システムの構成例を示す。
可視光通信システム１００は、レンズ２００、発光素子３００を有する送信基板４００、および、受光素子５００を有する受信基板６００を備え、外部の通信対象と通信を行う。 1 and 2 show a configuration example of a visible light communication system in an embodiment of the present invention.
The visible light communication system 100 includes a lens 200, a transmitting substrate 400 having a light emitting element 300, and a receiving substrate 600 having a light receiving element 500, and communicates with an external communication target.

受光素子５００はレンズ２００の焦点位置に実装されている。
送信基板４００は送信基板開口部４１０を有し、発光素子３００はレンズ２００の焦点位置の周囲に実装される。 The light receiving element 500 is mounted at the focal position of the lens 200.
The transmission substrate 400 has a transmission substrate opening 410, and the light emitting element 300 is mounted around the focal position of the lens 200.

本構成により、従来は送信用レンズおよび受信用レンズの２つのレンズが必要であったところ、送信用レンズが不要になり装置の小型化・低廉化が期待できる。特に大口径レンズを用いた長距離通信システムに用いる場合には、高価な大口径レンズが不要となり、コストを削減するとともに、軽量化を図ることも可能となる。
また、図２に記載のように、受信基板６００と送信基板４００との間に、放熱板４２０を有する構成とすることもできる。これにより、受光素子５００や発光素子３００に対して効率的に放熱を行うことができる。 With this configuration, conventionally, two lenses, a transmission lens and a reception lens, were required, but the transmission lens is not required, and the size and cost of the device can be expected to be reduced. Particularly when used in a long-distance communication system using a large-diameter lens, an expensive large-diameter lens is not required, which makes it possible to reduce the cost and reduce the weight.
Further, as shown in FIG. 2, the heat dissipation plate 420 may be provided between the receiving substrate 600 and the transmitting substrate 400. Thereby, heat can be efficiently radiated to the light receiving element 500 and the light emitting element 300.

図３は、本発明の一実施例における、可視光通信システム１００の構成例を示す。
本実施例においては、発光素子３００はレンズ２００の焦点位置方向に傾けて実装されている。この構成により、発光素子３００による光が、レンズ２００を通してより効率的に送信される。本実施例では、開口傾斜部４１１に配置された発光素子３００が、受光素子５００に近いため、受光素子の周囲に受光素子用遮蔽板６１０を設けているが、発光素子３００と受光素子５００の位置関係によっては、受光素子用遮蔽板６１０を用いない構成とすることもできる。
本実施例においては、送信基板４００における開口部４１０において、レンズ２００の焦点位置方向へ傾斜した開口傾斜部４１１を有する。これに代えて、送信基板４００は開口傾斜部を有さない構成とし、発光素子３００の台座を傾斜させる構成としてもよい。 FIG. 3 shows a configuration example of the visible light communication system 100 in the embodiment of the present invention.
In the present embodiment, the light emitting element 300 is mounted so as to be tilted in the focal position direction of the lens 200. With this configuration, the light emitted from the light emitting element 300 is more efficiently transmitted through the lens 200. In the present embodiment, since the light emitting element 300 arranged in the opening inclined portion 411 is close to the light receiving element 500, the light receiving element shielding plate 610 is provided around the light receiving element, but the light emitting element 300 and the light receiving element 500 have the same structure. Depending on the positional relationship, the light receiving element shield plate 610 may be omitted.
In this embodiment, the opening 410 in the transmission substrate 400 has an opening tilted portion 411 tilted in the focal position direction of the lens 200. Instead of this, the transmission substrate 400 may have a configuration that does not have an inclined opening portion, and the pedestal of the light emitting element 300 may be inclined.

図４、図５は、本発明の一実施例における、送信基板を示す。
本実施例において、送信基板開口部４１０は送信基板４００に設けられた円形の穴であり、レンズ２００の焦点位置の周囲に、複数の発光素子３００が円の周囲に等間隔に配置されている。
発光素子３００は、図４では４つであるが、図５では３つであり、それ以外の複数の発光素子３００でも、単一の発光素子３００でもよい。回路の設計上、等間隔に配置しないものとしてもよく、この場合、発光素子３００の強度を均一にする代わりに、発光素子３００の光の送信方向や配置場所に応じて、発光素子３００の強度を個々に設定してもよい。 4 and 5 show a transmission board according to an embodiment of the present invention.
In this embodiment, the transmission substrate opening 410 is a circular hole provided in the transmission substrate 400, and a plurality of light emitting elements 300 are arranged around the focal position of the lens 200 at equal intervals around the circle. .
The number of light emitting elements 300 is four in FIG. 4, but is three in FIG. 5, and a plurality of other light emitting elements 300 or a single light emitting element 300 may be used. Due to the circuit design, the light emitting elements may not be arranged at equal intervals. In this case, instead of making the light emitting elements 300 uniform in intensity, the intensity of the light emitting elements 300 may be changed according to the light transmitting direction of the light emitting elements 300 and the arrangement location. May be set individually.

図６は、本発明の一実施例における、送信基板を示す。
本実施例において、送信基板開口部４１０は送信基板４００に設けられた正方形の穴であり、レンズ２００の焦点位置の周囲に、４つの発光素子３００が等間隔に配置されている。
送信基板開口部４１０の形状は、円形や正方形以外に、楕円形、長方形や多角形など、回路の設計などに応じて選択することができる。
また、送信基板開口部４１０は穴である必要はない。つまり、例えば図７に示すように、送信基板４００はコの字状であり、その中央に開口を有するものとしてもよい。 FIG. 6 shows a transmission board according to an embodiment of the present invention.
In the present embodiment, the transmission substrate opening 410 is a square hole provided in the transmission substrate 400, and four light emitting elements 300 are arranged at equal intervals around the focal position of the lens 200.
The shape of the transmission substrate opening 410 can be selected according to the design of the circuit, such as an ellipse, a rectangle, or a polygon, as well as a circle or a square.
Also, the transmission board opening 410 need not be a hole. That is, for example, as shown in FIG. 7, the transmission substrate 400 may be U-shaped and may have an opening at the center thereof.

図８は、本発明の一実施例における、送信基板を示す。
本実施例において、送信基板４００は２つの送信基板副部４０１、４０２から構成され、複数の送信基板副部（４０１、４０２）の間に送信基板開口部４１０が形成されている。個々の送信基板副部（４０１、４０２）は、それぞれ２つの発光素子３００を有する。
本構成により、送信基板４００に穴を設けることなく、複数の送信基板副部４０１、４０２を実装するだけで、送信基板開口部４１０を形成することができる。 FIG. 8 shows a transmission board according to an embodiment of the present invention.
In this embodiment, the transmission board 400 is composed of two transmission board sub-portions 401 and 402, and a transmission board opening 410 is formed between the plurality of transmission board sub-portions (401, 402). Each of the transmission board sub-portions (401, 402) has two light emitting elements 300.
With this configuration, the transmission board opening portion 410 can be formed by mounting the plurality of transmission board sub-portions 401 and 402 without providing a hole in the transmission board 400.

図９は、本発明の一実施例における、送信基板を示す。
本実施例において、送信基板４００は４つの送信基板副部（４０３、４０４、４０５、４０６）から構成され、複数の送信基板副部（４０３、４０４、４０５、４０６）の間に送信基板開口部４１０が形成されている。そして、個々の送信基板副部（４０３、４０４、４０５、４０６）は、それぞれ１つの発光素子３００を有している。
送信基板副部（４０３、４０４、４０５、４０６）には、例えば、既成の、発光素子３００を有する発光ユニットを用いることができる。この場合、送信基板４００に穴を設けることなく、また、別途、複数の送信基板副部を製造する必要なく、複数の発光ユニットを実装するだけで、送信基板開口部（４０３、４０４、４０５、４０６）を形成することができる。 FIG. 9 shows a transmission board according to an embodiment of the present invention.
In this embodiment, the transmission board 400 is composed of four transmission board sub-portions (403, 404, 405, 406), and the transmission board openings are provided between the plurality of transmission board sub-portions (403, 404, 405, 406). 410 is formed. Each of the transmission board sub-portions (403, 404, 405, 406) has one light emitting element 300.
For the transmission board sub-portions (403, 404, 405, 406), for example, an existing light emitting unit having the light emitting element 300 can be used. In this case, the transmission board openings (403, 404, 405) can be formed by mounting a plurality of light emitting units without forming a hole in the transmission board 400 and separately manufacturing a plurality of transmission board sub-portions. 406) can be formed.

以上の例においては、受光素子５００がレンズ２００の焦点位置に、受光素子５００が焦点位置の周囲に配置されているため、受信信号の精度は１００％であるのに対し、送信信号の精度は受信信号の精度に比べると例えば７０％程度となる可能性がある。このため、例えば各センサからの信号を受信することがメインであり、必要に応じて各センサに信号を送信するような機器など、可視光信号の受信機能を主として利用し、発信機能を従として利用する場合にも、利用できる。   In the above example, since the light receiving element 500 is arranged at the focal position of the lens 200 and the light receiving element 500 is arranged around the focal position, the accuracy of the received signal is 100%, whereas the accuracy of the transmitted signal is Compared with the accuracy of the received signal, it may be about 70%, for example. Therefore, for example, the main purpose is to receive signals from each sensor, such as equipment that sends signals to each sensor as needed, mainly uses the visible light signal reception function, and the transmission function as a subordinate. It can also be used when using.

図１０は、本発明の一実施例における、可視光通信システム１００の構成例を示す。
本実施例においては、発光素子３００がレンズ２００の焦点位置に実装され、受光素子５００がレンズ２００の焦点位置の周囲に実装されている。この場合、図１に示される例における受信基板６００、発光基板、発光基板開口部を、それぞれ、発光基板、受信基板６００、受信基板６００開口部６１０として形成することもできる。
本構成により、高価な発光素子３００を用いる場合に、単一の発光素子３００で可視光通信システム固定部１００を形成することができ、コストを抑えることができる。 FIG. 10 shows a configuration example of the visible light communication system 100 in the embodiment of the present invention.
In this embodiment, the light emitting element 300 is mounted at the focal position of the lens 200, and the light receiving element 500 is mounted around the focal position of the lens 200. In this case, the receiving substrate 600, the light emitting substrate, and the light emitting substrate opening in the example shown in FIG. 1 can be formed as the light emitting substrate, the receiving substrate 600, and the receiving substrate 600 opening 610, respectively.
With this configuration, when the expensive light emitting element 300 is used, the visible light communication system fixing unit 100 can be formed with a single light emitting element 300, and the cost can be suppressed.

本構成においては、発光素子３００がレンズ２００の焦点位置に、受光素子５００が焦点位置の周囲に配置されているため、送信信号の精度は１００％であるのに対し、受信信号の精度は送信信号の精度に比べると例えば７０％程度となる可能性がある。このため、例えば通常は通信のハブとなる親機に測定信号を送信するのがメインであり、必要に応じて親機から信号を受信するようなセンサなど、可視光信号の発信機能を主として利用し、受信機能を従として利用する場合にも、利用できる。
別の実施例として、送信性能、つまり、発光性能が重視される場合には、発光素子３００を中心に配置する構成を採用し、受信性能、つまり、受光性能が重視される場合には、受光素子５００を中心に配置する構成を採用することができる。 In this configuration, since the light emitting element 300 is arranged at the focal position of the lens 200 and the light receiving element 500 is arranged around the focal position, the accuracy of the transmission signal is 100%, while the accuracy of the reception signal is the transmission. The accuracy of the signal may be about 70%, for example. Therefore, for example, the main function is to send measurement signals to the base unit, which normally serves as a communication hub, and it mainly uses visible light signal transmission functions such as sensors that receive signals from the base unit when necessary. However, it can also be used when the receiving function is used as a subordinate.
As another example, when the transmission performance, that is, the light emission performance is important, a configuration in which the light emitting element 300 is arranged in the center is adopted, and when the reception performance, that is, the light reception performance is important, the light reception is performed. A configuration in which the element 500 is arranged in the center can be adopted.

図１１は、本発明の一実施例における、可視光通信システム１００の構成例を示す。本実施例においては、監視カメラ７１１とモニタ７１２において、光通信が用いられている。
一般に、監視カメラ７１１からモニタシステム７１０へ送信されるデータ量は、モニタシステム７１０から監視カメラ７１１へ送信されるデータ量より多く、有線回線などであれば太い回線が必要であり、無線回線などであれば広い帯域が必要である。
本実施例においても、矢印Ｍで示される、監視カメラ７１１からモニタシステム７１０へ送信されるデータ量は、矢印Ｓで示される、モニタシステム７１０から監視カメラ７１１へ送信されるデータ量より多く、例えば１０倍から１０００倍、またはそれ以上である。
監視カメラ７１１からは主にデータの送信が行われるため、発光素子３００を中心に配置する構成を採用している。他方、モニタシステム７１０では主にデータの受信が行われるため、受光素子５００を中心に配置する構成を採用している。 FIG. 11 shows a configuration example of the visible light communication system 100 in the embodiment of the present invention. In this embodiment, optical communication is used in the monitoring camera 711 and the monitor 712.
Generally, the amount of data transmitted from the monitoring camera 711 to the monitor system 710 is larger than the amount of data transmitted from the monitor system 710 to the monitoring camera 711, and if a wired line or the like requires a thick line, a wireless line or the like is required. If so, a wide band is required.
Also in this embodiment, the amount of data transmitted from the monitoring camera 711 to the monitor system 710, which is indicated by the arrow M, is larger than the amount of data transmitted from the monitor system 710 to the monitoring camera 711, which is indicated by the arrow S, for example, It is 10 to 1000 times or more.
Since data is mainly transmitted from the surveillance camera 711, the light emitting element 300 is arranged in the center. On the other hand, since the monitor system 710 mainly receives data, the light receiving element 500 is arranged in the center.

The visible light communication system 100 is connected and fixed to the moving body 720 by the visible light system fixing portions (102, 103).

可視光通信システム固定部１００を備えた移動体は、例えば車両であり、車両の左右前方に２つ、後方に１つの可視光通信システム１００を有する。これにより、前方、左右、後方のいずれとも通信を行うことができる。
本実施例においては、可視光通信システム１００が小型化され軽量化が図られているため、車両自体も軽量化できる。 The moving body provided with the visible light communication system fixing unit 100 is, for example, a vehicle, and has two visible light communication systems 100 on the left and right sides of the vehicle and one visible light communication system 100 on the rear side. As a result, it is possible to communicate with the front, the left and the right, and the rear.
In the present embodiment, the visible light communication system 100 is made smaller and lighter, so that the vehicle itself can be made lighter.

本発明は以上の実施例に限定されることなく、本発明の趣旨を逸脱しない範囲で様々な実施例を含むことは言うまでもない。
例えば、霧など光通信が困難となる状況に備えて、電波通信システムを別途設け、可視光通信システムと電波通信システムを併用する構成とすることもできる。
It is needless to say that the present invention is not limited to the above embodiments and includes various embodiments without departing from the spirit of the present invention.
For example, in preparation for a situation where optical communication such as fog becomes difficult, a radio communication system may be separately provided and the visible light communication system and the radio communication system may be used together.
