Description

本発明は、照明器具と光通信用照明器具とが設置された空間において、光通信の通信範囲を利用者に識別可能に視認させる光通信範囲識別方法に関するものである。   The present invention relates to an optical communication range identification method for allowing a user to visually recognize a communication range of optical communication in a space where a lighting fixture and a lighting fixture for optical communication are installed.

光無線通信技術により、例えば照明光を利用して無線通信を行うことが可能であり、現在、建物空間内での利用が期待されている(非特許文献1参照)。   With optical wireless communication technology, it is possible to perform wireless communication using, for example, illumination light, and is currently expected to be used in a building space (see Non-Patent Document 1).

Specifically, it is desirable that the user can visually distinguish the irradiation range of light emitted from the lighting fixture for optical communication and the irradiation range of light emitted from the lighting fixture.

そこで、光の色温度の違いや光の光量の強弱で光通信の通信範囲を利用者に視認させる方法が考えられる。これにより、光通信の通信範囲を利用者に視認させることができるのは勿論、同時に、建築空間の雰囲気や利用者の視環境も変えることができる。具体的には、光の色温度の差を大きくすれば、緊張や弛緩といった利用者の心理に影響を与えることができ、また、光の照度の差を大きくすれば、利用者の視力に影響を与えることができる。   Therefore, a method is conceivable in which the user can visually recognize the communication range of the optical communication with the difference in the color temperature of the light or the intensity of the light amount. As a result, the communication range of optical communication can be visually recognized by the user, and at the same time, the atmosphere of the building space and the user's visual environment can be changed. Specifically, increasing the difference in light color temperature can affect the user's psychology such as tension and relaxation, and increasing the difference in light illuminance affects the user's visual acuity.

It is possible to know the communication range of optical communication only by confirming whether or not.

以下に、本発明にかかる光通信範囲識別方法の実施例を図面に基づいて詳細に説明する。なお、この実施例によりこの発明が限定されるものではない。また、本明細書において、「光」とは、電磁波であり、可視光を含むすべての光(例えば、ラジオ波やマイクロ波、赤外線、紫外線、X線、ガンマ線など)を意味する。換言すると、「光」には、人間が眼で色として認識できる波長域の電磁波である可視光だけでなく、人間が眼で色として認識できない波長域の電磁波も含まれる。   Embodiments of an optical communication range identification method according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments. In this specification, “light” is an electromagnetic wave and means all light including visible light (for example, radio waves, microwaves, infrared rays, ultraviolet rays, X-rays, gamma rays, etc.). In other words, “light” includes not only visible light that is an electromagnetic wave in a wavelength range that a human can recognize as a color but also an electromagnetic wave in a wavelength range that cannot be recognized as a color by an eye.

まず、一般の照明器具である照明器具102と、可視光通信で情報を発信する機能を備えた照明器具である光通信用照明器具100とが設置された空間について、図1および図2を参照して説明する。図1および図2は照明器具102と光通信用照明器具100とが設置された空間の一例を示す図である。図1および図2に示すように、本実施例における空間は建物内の空間であり、3台の照明器具102と1台の光通信用照明器具100とが天井に設置されている。なお、光通信用照明器具100および照明器具102の設置台数はこれに限定しない。また、図1および図2では、光通信用照明器具100から発せられた光と照明器具102から発せられた光とを視覚的に区別できるように、光通信用照明器具100から発せられた光の照射範囲(光通信の通信エリア)を、照明器具102から発せられた光の照射範囲を示す色とは異なる色と模様との組み合わせで示している。しかし、実際の空間では、光通信用照明器具100から発せられた光と照明器具102から発せられた光とは視覚的に区別できなくてもよい。   First, see FIGS. 1 and 2 for a space where a lighting fixture 102 that is a general lighting fixture and a lighting fixture for optical communication 100 that is a lighting fixture having a function of transmitting information by visible light communication are installed. To explain. 1 and 2 are views showing an example of a space in which the lighting fixture 102 and the optical communication lighting fixture 100 are installed. As shown in FIGS. 1 and 2, the space in this embodiment is a space in a building, and three lighting fixtures 102 and one lighting fixture 100 for optical communication are installed on the ceiling. In addition, the installation number of the lighting fixture 100 for optical communication and the lighting fixture 102 is not limited to this. 1 and 2, the light emitted from the optical communication lighting device 100 is visually distinguishable from the light emitted from the optical communication lighting device 100 and the light emitted from the lighting device 102. The irradiation range (communication area for optical communication) is indicated by a combination of a color and a pattern different from the color indicating the irradiation range of the light emitted from the luminaire 102. However, in an actual space, the light emitted from the lighting device for optical communication 100 and the light emitted from the lighting device 102 may not be visually distinguishable.

つぎに、光通信用照明器具100を含む光通信照明システムの構成について図3を参照して説明する。図3は光通信用照明器具100を含む光通信照明システムの構成の一例を示す図である。図3に示すように、光通信照明システムは光通信用照明器具100と受信器104とで構成されている。光通信用照明器具100は発光部100aと変調部100bと記憶部100cとを備えている。発光部100aは、可視光を発する可視光通信用の光源(通信用光源)であり、可視光で照明を行う。ここで、発光部100aおよび照明器具102に取り付ける照明光源として、発光部100aの分光強度分布(通信分光強度分布)における光強度から照明光源の分光強度分布(照明分光強度分布)における光強度を減算した値のうち少なくとも1つが所定値A(当該Aは、通信分光強度分布と照明分光強度分布とに基づいて決定された値である。)以上であるものを用いてもよい。また、後述する蛍光物質が吸収する短波長成分を含む光源を通信用光源として用い、その波長成分を少量しか含まない光源を照明光源として用いてもよい。なお、「少量」とは両光源の分光強度分布(後述する図4参照)の特定の波長領域内での光強度の積算値により相対的に決定されるものである。変調部100bは発光部100a(通信用光源)を変調して可視光通信で情報を発信する。記憶部100cは可視光通信で発信する情報を記憶する。受信器104は光通信用照明器具100から発信された情報を受信する機能を備えた携帯端末である。なお、本実施例では、受信器104に、後述する蛍光物質が塗られている。   Next, the configuration of an optical communication lighting system including the optical communication lighting device 100 will be described with reference to FIG. FIG. 3 is a diagram illustrating an example of a configuration of an optical communication lighting system including the optical communication lighting device 100. As shown in FIG. 3, the optical communication lighting system includes an optical communication lighting device 100 and a receiver 104. The optical communication lighting device 100 includes a light emitting unit 100a, a modulation unit 100b, and a storage unit 100c. The light emitting unit 100a is a light source for visible light communication (communication light source) that emits visible light, and performs illumination with visible light. Here, as an illumination light source attached to the light emitting unit 100a and the lighting fixture 102, the light intensity in the spectral intensity distribution (illumination spectral intensity distribution) of the illumination light source is subtracted from the light intensity in the spectral intensity distribution (communication spectral intensity distribution) of the light emitting unit 100a. At least one of the obtained values may be equal to or greater than a predetermined value A (the A is a value determined based on the communication spectral intensity distribution and the illumination spectral intensity distribution). Further, a light source including a short wavelength component absorbed by a fluorescent material to be described later may be used as a communication light source, and a light source including only a small amount of the wavelength component may be used as an illumination light source. The “small amount” is relatively determined by the integrated value of the light intensity in a specific wavelength region of the spectral intensity distribution (see FIG. 4 described later) of both light sources. The modulation unit 100b modulates the light emitting unit 100a (communication light source) and transmits information by visible light communication. The memory | storage part 100c memorize | stores the information transmitted by visible light communication. The receiver 104 is a portable terminal having a function of receiving information transmitted from the optical communication lighting device 100. In this embodiment, the receiver 104 is coated with a fluorescent material to be described later.

つぎに、光通信の通信範囲を利用者に識別可能に視認させるために用いる本発明の特徴である蛍光物質について図4から図6を参照して説明する。蛍光物質(具体的には蛍光塗料や蛍光材料や蛍光体など)は通信用光源から発せられた光に反応して蛍光を発する。具体的には、蛍光物質は、通信用光源に含まれており且つ照明光源に少量しか含まれていない短波長成分を可視波長域へ励起するものである。なお、「少量」とは両光源の分光強度分布(図4参照)の特定の波長領域内での光強度の積算値により相対的に決定されるものである。   Next, a fluorescent material that is a feature of the present invention and is used to make a user visually recognize a communication range of optical communication will be described with reference to FIGS. A fluorescent substance (specifically, a fluorescent paint, a fluorescent material, or a phosphor) emits fluorescence in response to light emitted from a communication light source. Specifically, the fluorescent substance excites a short wavelength component contained in the communication light source and a small amount in the illumination light source to the visible wavelength range. The “small amount” is relatively determined by the integrated value of the light intensity within a specific wavelength region of the spectral intensity distribution (see FIG. 4) of both light sources.

ここで、通信用光源および照明光源として、通信用光源の分光強度分布(通信分光強度分布)における光強度から照明光源の分光強度分布(照明分光強度分布)における光強度を減算した値のうち少なくとも1つが所定値A以上であるものを用いた場合、蛍光物質として、所定値A以上である値を算出した際の光強度に対応する波長を含む波長領域のうち、通信分光強度分布におけるその波長領域内の光強度の積算値から照明分光強度分布における当該その波長領域内の光強度の積算値を減算した値が最大または所定値B(当該Bは、通信分光強度分布と照明分光強度分布とに基づいて決定された値である。)以上となる波長領域内の光に反応して蛍光を発するものを用いてもよい。具体的には、照明光源の波長分布が図4のaに示すものであり且つ通信用光源の波長分布が図4のbに示すものである場合、蛍光物質として図4のcに示す波長分布のものを用いてもよい。また、具体的には、蛍光物質として、図5に示す化学構造を有し紫外線を当てると緑色の光を放つ特徴を持つ色素であるフルオレセイン(fluorescein)や、図6に示す化学構造を有する蛍光染料であるスチルベン系蛍光漂白剤を用いてもよい。   Here, as the communication light source and the illumination light source, at least of the values obtained by subtracting the light intensity in the spectral intensity distribution (illumination spectral intensity distribution) of the illumination light source from the light intensity in the spectral intensity distribution (communication spectral intensity distribution) of the communication light source. When one of which has a predetermined value A or more is used, the wavelength in the communication spectral intensity distribution in the wavelength region including the wavelength corresponding to the light intensity when the value of the predetermined value A or more is calculated as the fluorescent material. A value obtained by subtracting the integrated value of the light intensity in the wavelength region in the illumination spectral intensity distribution from the integrated value of the light intensity in the region is a maximum or a predetermined value B (B is a communication spectral intensity distribution, an illumination spectral intensity distribution, and It is a value determined based on the above.) A substance that emits fluorescence in response to light in the above wavelength region may be used. Specifically, when the wavelength distribution of the illumination light source is as shown in FIG. 4a and the wavelength distribution of the communication light source is as shown in FIG. 4b, the wavelength distribution shown in FIG. May be used. Specifically, as a fluorescent substance, fluorescein, which is a dye having a chemical structure shown in FIG. 5 and emits green light when irradiated with ultraviolet rays, or a fluorescent substance having a chemical structure shown in FIG. A stilbene fluorescent bleaching agent that is a dye may be used.

そして、光通信の通信範囲を利用者に識別可能に視認させるために、上述した蛍光物質を、利用者の身体の所定の部分、利用者が携帯する物、所定の場所などに塗布する。具体的には、利用者の手や腕に蛍光物質を塗ってもよい。また、蛍光物質が塗られた紙を利用者に携帯させてもよい。また、空間内の室内構成要素(具体的には床面(床材)や内装材、什器など)に蛍光物質を塗ってもよい。ここで、本実施例では、蛍光物質を受信器104に予め塗布しているので、図3に示すように、受信器104は、光通信範囲内でのみ発光し、光通信範囲外では発光しない。   Then, in order to allow the user to visually recognize the communication range of optical communication, the above-described fluorescent material is applied to a predetermined part of the user's body, an object carried by the user, a predetermined place, and the like. Specifically, a fluorescent material may be applied to the user's hand or arm. In addition, a user may carry paper coated with a fluorescent material. Moreover, you may apply a fluorescent substance to the indoor component in a space (specifically floor surface (floor material), interior material, furniture, etc.). Here, in this embodiment, since the fluorescent material is preliminarily applied to the receiver 104, as shown in FIG. 3, the receiver 104 emits light only within the optical communication range and does not emit light outside the optical communication range. .

以上、説明したように、本実施例によれば、照明器具102と光通信用照明器具100とが設置された空間において、光通信の通信範囲を利用者に識別可能に視認させるにあたって、通信用光源から発せられた光に反応して蛍光を発する蛍光物質を、利用者の身体の所定の部分、利用者が携帯する物および所定の場所のうち少なくとも1つに塗布する(練りこむ、貼り付ける)ので、照明器具102と光通信用照明器具100とが設置された空間において、建築空間の雰囲気や利用者の視環境を変えることなく光通信の通信範囲を利用者に識別可能に視認させることができる。具体的には、空間内で、利用者は、蛍光物質を塗った手を照明にかざし、手が発光しているかを確認するだけで、光通信の通信範囲を知ることができる。換言すると、利用者の手に蛍光物質を予め塗っておき、利用者がその手を照明にかざせば、通信用照明器具の下でのみ利用者の手が発光するので、利用者は、手が発光しているかを確認するだけで、光通信の通信範囲を知ることができる。また、空間内で、利用者は、予め渡された蛍光物質が塗られた紙を照明にかざし、紙が発光しているかを確認するだけで、光通信の通信範囲を知ることができる。換言すると、蛍光物質を塗った紙を利用者に予め渡しておき、利用者がその紙を照明にかざせば、通信用照明器具の下でのみ紙が発光するので、利用者は、紙が発光しているかを確認するだけで、光通信の通信範囲を知ることができる。また、空間内の室内構成要素(具体的には床面(床材)や内装材、什器など)に蛍光物質を予め塗っておけば、通信用照明器具の下の床面(床材)や内装材、什器などが特定の色や輝度で発光するので、利用者は、床面(床材)や内装材、什器などが発光しているかを確認するだけで、光通信の通信範囲を知ることができる。   As described above, according to the present embodiment, in the space where the luminaire 102 and the luminaire for optical communication 100 are installed, the communication range for optical communication can be visually recognized by the user in an identifiable manner. A fluorescent substance that emits fluorescence in response to light emitted from a light source is applied (kneaded or pasted) to at least one of a predetermined part of the user's body, an object carried by the user, and a predetermined place. Therefore, in the space where the lighting fixture 102 and the lighting fixture for optical communication 100 are installed, the user can visually recognize the communication range of the optical communication without changing the atmosphere of the architectural space and the viewing environment of the user. Can do. Specifically, in the space, the user can know the communication range of optical communication simply by holding a hand coated with a fluorescent material over illumination and checking whether the hand emits light. In other words, if the user's hand is preliminarily coated with a fluorescent material and the user holds the hand over lighting, the user's hand emits light only under the communication lighting device. It is possible to know the communication range of optical communication simply by confirming whether light is emitted. Further, in the space, the user can know the communication range of the optical communication simply by holding the paper coated with the fluorescent material delivered in advance to the illumination and confirming whether the paper emits light. In other words, if the paper coated with the fluorescent material is handed over to the user in advance, and the user holds the paper over the illumination, the paper emits light only under the communication lighting device. It is possible to know the communication range of optical communication simply by confirming whether or not the communication is being performed. In addition, if fluorescent materials are applied in advance to indoor components in the space (specifically, the floor surface (floor material), interior materials, furniture, etc.), the floor surface (floor material) under the communication lighting fixture or Since interior materials and fixtures emit light with a specific color and brightness, users can know the communication range of optical communications simply by checking whether the floor (floor material), interior materials, and fixtures are emitting light. be able to.

ここで、光通信用照明器具が空間内の通常の照明器具と混ざって設置されている場合、例えば利用者が天井を見上げて光通信用照明器具を視覚的に判別することで、利用者が光通信用照明器具を確認する状況が考えられる。しかし、そのような状況は稀であり、さらに普通の利用者はどの照明器具が光通信用のものであるかをその外観から判別することは困難である。そして、仮に利用者が光通信用照明器具を確認することができたとしても、利用者の手元では光通信用照明器具から発せられた光が例えばその隣の通常の照明器具から発せられた光と混ざってしまうので、利用者は光通信用照明器具から発せられた光がどこまで届いているのかを知ることが困難である。つまり、利用者にとって、光通信の通信範囲(情報の受信エリア)を知ることが困難である。そこで、本発明を実施すれば、通常の照明器具と光通信用照明器具とが設置された空間において、利用者は光通信の通信範囲を容易に知ることができ、利用者の混乱を防ぐことができる。しかも、本発明を実施しても建築空間の雰囲気や利用者の視環境が変わることはないので、光通信を実現する際、本発明を手軽に導入することができる。また、本発明は通信技術に依存しない方法であるので、通信時間の遅れが生じず、高速移動中でも利用可能である。また、光通信用照明器具の位置が頻繁に変更されるような場所で本発明を適用しても通信エリアを説明する案内表示などを変更する作業は不要であるので、このような場所でも本発明を手軽に導入することができる。   Here, when the optical communication lighting device is installed in a mixture with a normal lighting device in the space, for example, the user looks up at the ceiling and visually identifies the optical communication lighting device, so that the user can A situation where the lighting equipment for optical communication is confirmed can be considered. However, such a situation is rare, and it is difficult for ordinary users to determine from the appearance which lighting apparatus is for optical communication. Even if the user can confirm the lighting fixture for optical communication, the light emitted from the lighting fixture for optical communication is, for example, light emitted from the adjacent normal lighting fixture at the user's hand. It is difficult for the user to know how far the light emitted from the lighting device for optical communication has reached. That is, it is difficult for the user to know the communication range (information reception area) of optical communication. Therefore, if the present invention is implemented, the user can easily know the communication range of the optical communication in the space where the normal lighting fixture and the lighting fixture for optical communication are installed, and prevent confusion of the user. Can do. Moreover, even if the present invention is implemented, the atmosphere of the building space and the user's visual environment do not change, so that the present invention can be easily introduced when realizing optical communication. Further, since the present invention is a method that does not depend on communication technology, there is no delay in communication time, and it can be used even during high-speed movement. Further, even if the present invention is applied in a place where the position of the lighting fixture for optical communication is frequently changed, there is no need to change the guidance display for explaining the communication area. The invention can be easily introduced.

また、本実施例によれば、通信用光源および照明光源において、通信分光強度分布における光強度から照明分光強度分布における光強度を減算した値のうち少なくとも1つは所定値A以上であり、蛍光物質は、所定値A以上である値を算出した際の光強度に対応する波長を含む波長領域のうち、通信分光強度分布におけるその波長領域内の光強度の積算値から照明分光強度分布における当該その波長領域内の光強度の積算値を減算した値が最大または所定値B以上となる波長領域内の光に反応して蛍光を発するものであるので、光通信の通信範囲をより一層識別し易くすることができる。   According to the present embodiment, in the communication light source and the illumination light source, at least one of the values obtained by subtracting the light intensity in the illumination spectral intensity distribution from the light intensity in the communication spectral intensity distribution is equal to or greater than the predetermined value A, and the fluorescence Of the wavelength region including a wavelength corresponding to the light intensity when a value equal to or greater than the predetermined value A is calculated, the substance in the illumination spectral intensity distribution corresponds to the integrated value of the light intensity in the wavelength region in the communication spectral intensity distribution. Since the fluorescent light is emitted in response to the light in the wavelength region where the value obtained by subtracting the integrated value of the light intensity in the wavelength region is the maximum or the predetermined value B or more, the communication range of the optical communication is further identified. Can be made easier.

また、本実施例によれば、物は、光通信用照明器具100から発信された情報を受信する機能を備えた携帯端末であるので、利用者は、蛍光物質が塗られた携帯端末が発光しているかを確認するだけで、光通信の通信範囲を知ることができる。換言すると、蛍光物質が塗られた専用の携帯端末を利用者に予め渡しておき、利用者は当該携帯端末を光に当たるように持っていれば、通信用照明器具の下でのみ携帯端末が発光するので、利用者は、携帯端末が発光しているかを確認するだけで、光通信の通信範囲を知ることができる。   In addition, according to the present embodiment, since the object is a portable terminal having a function of receiving information transmitted from the lighting device for optical communication 100, the user emits light from the portable terminal coated with the fluorescent material. It is possible to know the communication range of optical communication simply by confirming whether or not the communication is being performed. In other words, if a dedicated portable terminal coated with a fluorescent material is handed over to the user in advance and the user holds the portable terminal so that it is exposed to light, the portable terminal emits light only under a communication lighting fixture. Therefore, the user can know the communication range of optical communication only by confirming whether the portable terminal emits light.

以上のように、本発明にかかる光通信範囲識別方法は、建築空間の雰囲気や利用者の視環境を変えることなく光通信の通信範囲を利用者に識別可能に視認させることができ、特に建築空間において可視光通信を実施する場合に好適である。   As described above, the optical communication range identification method according to the present invention allows the user to visually recognize the communication range of optical communication without changing the atmosphere of the building space or the visual environment of the user, This is suitable for performing visible light communication in a space.
