  The present invention relates to an illumination system and the like, and more particularly, to an illumination system and the like that can illuminate a predetermined position (region) of a room with a predetermined color.

Conventionally, fluorescent lamps and discharge lamps having different color rendering properties such as warm colors and cold colors are known. In addition, lighting devices that use these to switch color rendering properties are known. Specifically, the first and second discharge lamps having different light colors are connected to a common constant power type lighting device, and a switching means is interposed between each discharge lamp and the lighting device, so that any one of the discharge lamps. There is a technology that enables a light color variable discharge lamp lighting device, a luminaire, and a lighting system to be relatively economically provided so that both can be selectively and evenly lit (see Patent Document 1). Other similar techniques are disclosed in Patent Document 2, Patent Document 3, Patent Document 4, and the like.

  That is, when a large number of lighting fixtures are provided in the room and illumination is performed according to the purpose of use, it is necessary to appropriately set the luminous intensity of each lighting device, the illuminance at each position in the room, and the like. For example, in a meeting, lighting that induces a sense of tension is necessary. In addition, lighting is necessary so that all attendees can see their faces. In presentations, it may be required to brighten the vicinity of the podium and slightly darken the vicinity of the audience. On the other hand, when participants relax and talk to each other, it is preferable to illuminate in a warm mood, illuminate only around the participants and darken the rest. For this purpose, it is necessary to make it possible to easily and flexibly set and change the luminosity of a large number of lighting fixtures and the illuminance at each position. In addition, it is desired that the color of the light source can be switched to a warm color or a cold color, and that the intermediate color can be set flexibly from a warm color to a cold color.

(Embodiment 1)

In Embodiment 1, a lighting device in which a plurality of first lighting fixtures capable of changing color rendering properties are arranged in an illumination area, and information on the color rendering properties and luminous intensity of the plurality of first lighting fixtures (hereinafter referred to as a first lighting fixture). Color rendering light intensity information is stored, the color rendering light intensity information is supplied to the lighting device, and the lighting device is caused to perform a plurality of types of lighting having different light intensity distributions from the color rendering property distribution of the lighting area. An illumination system including an illumination control device will be described. The color rendering light intensity information is represented by a set of light intensity information of a plurality of light sources having different light emission spectrum distributions, or a set of information defining light emission spectra and light intensity of a plurality of light sources capable of changing the light emission spectrum distribution. Information. Light sources with different emission spectral distributions are different from light sources that have different color rendering properties due to different spectral envelopes, such as warm fluorescent lamps and cold fluorescent lamps that have been used for a long time. There is a fluorescent light source that causes a difference in sex, but the type of light source is not limited.
FIG. 1 shows a configuration block diagram of the illumination system according to Embodiment 1 of the present invention. The lighting system includes a lighting control device 100 and a lighting device 200.

  The lighting device 200 includes a plurality of lighting fixtures installed on the ceiling of the room and illuminates an illumination area around the lighting fixture group. The color rendering properties and light intensity of each lighting fixture are controlled by the lighting control device 100, and the lighting device 200 creates a color rendering property distribution and a light intensity distribution in the illumination area. The plurality of lighting fixtures Lij (i = 1 to 5, j = 1 to 3) in the present embodiment each include two fluorescent lamps, a warm color light source and a cold color light source, and the luminous intensity of each fluorescent lamp, that is, It is assumed that the intensity of warm color and the intensity of cold color can be adjusted. By changing the ratio of the warm color intensity to the cold color intensity, the color rendering can be changed between the warm color and the cold color. In order to control the luminous intensity of each fluorescent lamp, the inverter is turned on, and the lighting time rate may be controlled by the instructed luminous intensity value. Each lighting fixture Lij incorporates an inverter lighting circuit, and when the light intensity information is supplied to the inverter lighting circuit, the lighting time rate is controlled according to the light intensity information.

  The lighting control device 100 includes an operation unit 10, a control unit 11, a storage unit 12, and a luminous intensity information transmission unit 13, and selects a lighting mode, which will be described later, and warm and cold light intensity of each lighting fixture corresponding to the mode. In other words, the lighting control device 100 instructs the color rendering properties and the luminous intensity. The mode is information indicating the lighting status, and includes, for example, an energy saving mode, a presentation mode, a conference mode, and a conversation mode. The operation unit 10 includes, for example, an “energy saving mode” switch, a “presentation mode” switch, a “conference mode” switch, and a “discourse mode” switch. The operation unit 10 includes, for example, a touch panel for setting the above mode, a display, and an instruction receiving unit that receives an instruction from a user. The instruction receiving means receives a mode selection instruction from the user. The instruction reception is not limited to the touch on the touch panel, but various instructions such as an instruction by a mouse, an instruction by pressing a hardware button, and the like can be considered.

  The storage unit 12 stores color rendering light intensity information, which is information related to color rendering properties and light intensity corresponding to each mode. The color rendering light intensity information is, for example, a table composed of one or more records having “lighting fixture name”, “warm color light intensity”, and “cold light intensity”. “Lighting fixture name” is information for identifying a lighting fixture. “Warm color luminous intensity” is the luminous intensity of a fluorescent lamp of a warm color light source. The “cold luminosity” is the luminosity of a fluorescent light of a cold light source. However, the data structure of the color rendering light intensity information is not limited.

  The control unit 11 monitors ON / OFF of each switch, and when any mode switch is turned ON, the color rendering light intensity information corresponding to the corresponding mode stored in the storage unit 12 is read and the light intensity information is transmitted. The color rendering light intensity information is supplied to the lighting device 200 via the unit 13.

  An example of a table of color rendering luminous intensity information stored in the storage unit 12 is shown in FIG. The table stores the names of lighting fixtures to which the numbers (i, j) of the lighting fixtures Lij are assigned. Further, the color rendering light intensity information includes information regarding color rendering properties and light intensity (hereinafter referred to as first information). This first information is warm color luminous intensity information and cold color luminous intensity information. The warm color luminous intensity information is the luminous intensity of the fluorescent lamp of the warm color light source. The cold light intensity information is the light intensity of the fluorescent light of the cold light source. In the table of color rendering light intensity information in FIG. 2, warm color light intensity information and cold color light intensity information are stored as a pair of data corresponding to each lighting fixture name. Note that the format of the first information is not limited to this format, as will be described later.

  FIG. 2A is a table of color rendering light intensity information in the “conference mode”. Warm color luminous intensity information and cold color luminous intensity information for each lighting fixture Lij are stored as a pair of data. In the “conference mode”, only cold-colored lighting is used. FIG. 2B shows the case of the “Discourse mode” table, in which only warm color illumination is used, the warm color luminous intensity at a specific position is increased, and the warm color luminous intensity is reduced in the surrounding area. FIG. 2 (C) shows a case of a “presentation mode” table suitable for presentations and the like. Lighting fixtures L11, L12, and L13 close to the podium are set to 100% cold light intensity, and lighting fixtures L51, L52, and L53 close to the entrance are set. Illuminate dimly with a warm color intensity of 20%.

  The luminous intensity information sending unit 13 sends warm color luminous intensity information and cold luminous intensity information corresponding to each lighting fixture Lij of the lighting device 200. For transmission, for example, a separate transmission path is used for each of the warm fluorescent lamp and the cold fluorescent lamp of each lighting fixture Lij. Specifically, the warm-color light intensity information and the cold-color light intensity information may be sent from the light intensity information transmitting unit 13 to each lighting fixture Lij through 15 × 2 = 30 transmission lines. However, other methods may be used for transmitting the warm color light intensity information and the cold color light intensity information. For example, the luminous intensity information sending unit 13 transmits all warm color luminous intensity information and all cold luminous intensity information to all lighting fixtures Lij, and all the lighting fixtures Lij acquire only the warm coloring luminous intensity information and / or cold luminous intensity information addressed to themselves. But it ’s okay. In such a case, information (for example, ij) for identifying the luminaire Lij from which it is to be acquired is added to the warm color luminous intensity information and the cold color luminous intensity information transmitted by the luminous intensity information transmitting unit 13. The lighting fixture Lij stores information for identifying itself, and obtains warm color luminous intensity information and / or cold color luminous intensity information based on the identification information.

  The storage unit 12 is preferably realized by a non-volatile recording medium such as a hard disk, but may be realized by a volatile recording medium such as a RAM. The control unit 11 can be configured by an MPU and a memory, and can be realized by storing a processing program in the memory. However, the control unit 11 can also be realized by dedicated hardware (circuit).

  The color rendering light intensity information may be transmitted from the lighting control device 100 to the lighting device 200 via a LAN line. For this purpose, packet transmission can be applied. When packet transmission is applied, for example, a luminaire identification code storage area, a warm / cold color identification code area, and a luminous intensity information area are provided in each packet. The luminaire identification code storage area stores the luminaire identifier, for example, ij = 11 to 53, and “ij” in the case of the luminaire Lij. The warm color / cold color identification code area stores either “1” as the warm color identifier and “0” as the cold color identifier. A numerical value from 0% to 100% of the color rendering / lighting information table is stored in the luminous intensity information area. Each lighting fixture Lij of the lighting device 200 examines each identifier of the received packet, thereby obtaining warm color luminous intensity information and cold color luminous intensity information addressed to each of the lighting fixtures Lij (i = 1 to 5, j = 1 to 3). It is possible to acquire and control the warm color intensity of the warm color fluorescent lamp and the cold color intensity of the cold color fluorescent lamp. In addition, as a LAN line, you may connect each lighting fixture Lij and the luminous intensity information transmission part 13 with a wired LAN line. Further, each lighting fixture Lij is connected by a wired LAN line, and a wireless LAN terminal that performs wireless reception is further coupled to the wired LAN line, and a wireless LAN system is connected from the light intensity information transmitting unit 13 to the wireless LAN terminal. Thus, the color rendering light intensity information may be transmitted. If a communication system using a power line is applied as a wired LAN line, wiring work is simplified. Moreover, you may connect the luminous intensity information transmission part 13 and each of each lighting fixture Lij by a wireless LAN system. Alternatively, the lighting fixtures Lij may be sent in a time-division manner in a time slot of 15 × 2 = 30 lighting fixtures assigned to each warm color and cold color. A predetermined synchronization code is arranged at the head of the time slot. The lighting fixture Lij acquires information on its own time slot with reference to the synchronization signal.

  The luminous intensity information sending unit 13 transmits the packet to each lighting fixture Lij by a wireless method. The lighting fixture Lij has a built-in receiver, receives the packet by the receiver, and sends a packet addressed to the lighting fixture Lij itself. The warm color luminous intensity information and the cold color luminous intensity information are obtained and the luminous intensity of each of the warm fluorescent lamp and the cold fluorescent lamp may be controlled to the value described in the color rendering luminous intensity information table. That is, the information communication means of the luminous intensity information sending unit 13 may be a wired communication means, a wireless communication means, a broadcasting means, or the like.

Color rendering light intensity information may be set such that a part of the room is suitable for the conference mode and the other part is suitable for the discourse mode. Set some luminaires or all luminaires, not just warm colors or cold colors, to light intensity values for both warm and cold colors, so that the lighting is an intermediate color rendering with a mixture of warm and cold colors. Needless to say, it may be.
As described above, in the present embodiment, illumination having color rendering properties and luminous intensity suitable for each mode can be realized.

Further, in this embodiment, the lighting fixture Lij can control the color rendering properties from warm to cold as the lighting fixture Lij by controlling the luminous intensity of the warm fluorescent lamp and the cold fluorescent lamp to a predetermined luminous intensity as the lighting fixture Lij. It was used. As the luminaire Lij, a light source whose color rendering property can be changed by one light source itself may be used. When such a light source is used, the first information may be information representing color rendering properties by a combination of warm color luminous intensity information and cold color luminous intensity information, but information representing the color rendering properties themselves and the luminous intensity of the color. You may make it control light emission of the lighting fixture Lij by making the combination of two information into the format of 1st information. In such a case, each table of FIG. 2 is provided with columns of color rendering property information and light intensity information instead of the values of warm color light intensity and cold color light intensity, and is stored as first information for each lighting fixture Lij. What should I do? That is, the first information in the color rendering light intensity information is information in a form adapted to the method for controlling the color rendering properties and the light intensity in the lighting fixture Lij.
A plurality of mode tables may be provided for each of the conference mode and the talk mode, and one of the plurality of mode tables may be selected and used.

Color rendering light intensity information for each mode is created in a memory card, and the information in the memory card is read out by a memory card reader provided in the illumination control device 100 and supplied to the control unit 11. It may be copied to a memory card table in the section 12 and used as color rendering light intensity information. When the memory card is inserted into the memory card reader, the control unit 11 may receive the color rendering light intensity information of the memory card and send it to the illumination device 100 for illumination. In such a case, the operation of a mode selection button or the like becomes unnecessary.
(Embodiment 2)

  In general meeting rooms, the same type of lighting fixtures are often placed on the ceiling as in Embodiment 1. However, in multi-purpose halls, some lighting fixtures are dedicated to warm colors or indirect lighting. There is also a case. The embodiment thus configured will be described.

  In the second embodiment, one or more first lighting fixtures capable of changing the color rendering properties and a plurality of second lighting fixtures that do not control the color rendering properties are provided, and the first lighting fixture and the second lighting fixture are provided. Illumination apparatus in which the lighting fixtures are arranged in a lighting area, first information on the color rendering properties and luminous intensity of the first lighting fixtures, and second information on the luminous intensity of the second lighting fixtures. And an illumination control device that supplies the color rendering light intensity information to the illumination device and causes the illumination device to perform a plurality of types of illumination having different light intensity distributions from the color rendering properties distribution of the illumination area. To do. As a specific example, another lighting fixture is added to the lighting fixture Lij that can control color rendering properties and luminous intensity.

  In FIG. 3, in addition to the lighting fixture Lij, the lighting device 200a installs 16 lighting fixtures Lwk (k = 1 to 16) for indirect lighting on the wall surface of the room. The color rendering property of the lighting fixture Lwk is fixed, and only the light intensity can be controlled. By setting the color rendering properties and luminous intensity of the 15 lighting fixtures Lij and the luminous intensity of the 16 lighting fixtures Lwk to desired values, the illumination area is controlled to various color rendering properties and luminous intensity distributions.

FIG. 4 is an example of color rendering light intensity information stored in the storage unit 12. In the color rendering light intensity information of the “conference mode” in FIG. 4A, the light intensity value in the warm color light intensity column of the lighting fixture Lwk is set to 0%. Since the luminaire Lwk is dedicated to warm color illumination, data in the cold color intensity column is not necessary. Since the lighting fixtures Lij are all cold-colored illumination, the entire illumination area has a color rendering distribution suitable for a conference. In the color rendering light intensity information of “Discourse mode” in FIG. 4B, the light intensity value in the warm color light intensity column of the lighting fixture Lwk is set to a value of 40% to 80%. Data in the cold light intensity column is not necessary. As for the lighting fixture Lij, only the vicinity of the lighting fixture L32 in the center of the room is 80% warm color lighting, and the others are 0%. Such color rendering and light intensity distribution create a warm atmosphere and facilitate conversations with a small number of people.
In this embodiment, in addition to a lighting fixture having a specific color rendering property and its spatial distribution, for example, a spotlight, the luminous intensity information of the lighting fixture may be added to the color rendering luminance information.
Further, the illumination control device in the present embodiment is the same as the illumination control device in the first embodiment.
(Embodiment 3)
In the present embodiment, a lighting system capable of performing a plurality of types of lighting with different color rendering properties and luminous intensity distributions in a lighting area even when the color rendering properties of the lighting fixture alone cannot be changed will be described.

  In other words, this lighting system includes a plurality of lighting fixtures having light sources having different color rendering properties, distributed in an illumination area, and information having luminous intensity information corresponding to each color rendering property of each lighting device. A lighting control device for storing color rendering light intensity information, supplying the color rendering light intensity information to the lighting device, and causing the lighting device to perform a plurality of types of lighting having different light intensity distributions from the color rendering property distribution of the lighting area; It is a lighting system. The illumination area is an area where illumination is performed, and includes, for example, a conference room, a hall, a general household room, and an outdoor room.

  FIG. 5 shows an example in which a plurality of types of lighting fixtures having different color rendering properties are used, although the color rendering properties cannot be changed. In the lighting device 200b of FIG. 5, 20 lighting fixtures having a warm color light source and 20 lighting fixtures having a cold color light source are alternately arranged.

FIG. 6 shows an example of color rendering light intensity information for the lighting device 200b. In the color rendering light intensity information of the “conference mode” in FIG. 6A, only the luminaire having the cold light source has the light intensity value information of 100%. In the color rendering light intensity information of “Discourse mode” in FIG. 6B, the light intensity information of the lighting apparatus having the warm color light source located in the center of the room is increased to 100%, and the lighting apparatus having the warm color light source in the periphery of the room The luminous intensity information is as small as 20%.
The operation unit 10 of the illumination control apparatus 100 receives a mode selection. Next, the control unit 11 reads the color rendering light intensity information corresponding to the mode. Next, the luminous intensity information sending unit 13 sends the color rendering luminous intensity information to the lighting device 200.
Next, each lighting fixture of the lighting device 200b emits light at a light intensity corresponding to the received color rendering light intensity information. In addition, since the lighting fixture which emits light with the instruct | indicated luminous intensity is well-known, detailed description is abbreviate | omitted.
As described above, according to the present embodiment, it is possible to provide an illumination system capable of performing a plurality of types of illumination in which the color rendering property distribution and the luminous intensity distribution of the illumination area are different even when the color rendering property cannot be changed by the lighting fixture alone. .
In the present embodiment, if the arrangement density of the lighting fixtures is made dense, a plurality of types of color rendering illumination are mixed well, and intermediate color rendering properties can be easily obtained.
(Embodiment 4)

  For home lighting, it is better to use cold-colored lighting in the morning to get healthy, and warm-colored lighting from evening to night. In this way, the comfort of lighting increases, and lighting that matches human sensitivity can be realized. In the present embodiment, the ratio of the warm color intensity to the cold color intensity is changed according to the transition of time of day. For this purpose, as the color rendering light intensity information shown in FIGS. 2, 4 and 6, three color rendering light intensity information of morning color rendering light information, afternoon color rendering light intensity information, and night color rendering light intensity information are stored. In addition, if the control unit 11 switches the color rendering light intensity information to be selected in the morning, afternoon and evening, illumination suitable for the time zone can be automatically realized. That is, the control unit 11 further includes time acquisition means. And the control part 11 performs the illumination control which changes a color rendering property based on the information of the time which the time acquisition means acquired. The time acquisition unit may acquire the time from a clock built in the lighting control device, or may acquire the time from an external clock or the like.

Specifically, the storage unit 12 includes color rendering light intensity information for morning (for example, from 5:00 to 11:59) and color rendering light intensity information for the afternoon (for example, from 12:00 to 16:59). And color rendering light intensity information for the night (for example, from 17:00 to 4:59) is stored. Here, the color rendering light intensity information for morning use is usually information that gives a cold-colored illumination. On the other hand, normally, the color rendering luminous intensity information for the afternoon is information that gives a warm color-centered illumination.
And the time acquisition means of the control part 11 acquires time, and based on this time, the control part 11 selects and acquires color rendering light intensity information.
Next, the luminous intensity information sending unit 13 sends the color rendering luminous intensity information acquired by the control unit 11 to each lighting device 200.

  Next, each lighting device 200 receives the color rendering light intensity information, determines the light intensity based on its own information, and emits light corresponding to the light intensity. Note that the operation of the illumination control device and the illumination device after acquiring the color rendering light intensity information is the same as the operation of each device in the above embodiment.

  Note that the control unit 11 of the lighting control device may gradually change the value of the light intensity included in the color rendering light intensity information and supply it to the lighting device 200 as time elapses. As a result, the color rendering property distribution and the luminous intensity distribution change smoothly. For example, the storage unit 12 holds different color rendering light intensity information every time the time is different by 10 minutes, the control unit 11 reads different color rendering light intensity information every 10 minutes, and the light intensity information transmission unit 13 The read color rendering light intensity information is transmitted, and the lighting device 200 emits light based on the color rendering light intensity information.

Color rendering property information and luminous intensity information of each lighting fixture Lij, lighting fixture Lwk, etc. are stored as color rendering luminous intensity information in the storage unit 12 in the form of a time change characteristic of the day, and the control unit 11 reads the color rendering luminous intensity information. Then, it may be supplied to each lighting fixture. As described in the first embodiment, when the lighting fixture Lij includes the warm color fluorescent lamp and the cold color fluorescent lamp, the warming light intensity information and the cold color light intensity information are stored in the storage unit 12 as time variation characteristics of one day. That's fine. In addition, information such as color rendering property information, light intensity information, warm color light intensity information, and cold color light intensity information of each lighting fixture, which is element information of the color rendering light intensity information, is represented as a function of time, and this function generation is performed inside the control unit 11. In this case, the color rendering light intensity information may be acquired and supplied to the lighting device 200 via the light intensity information transmission unit 13. Function generation can be performed by a program. In this case, a table of color rendering light intensity information is not required in the storage unit 12. Instead, the function unit information and the parameter information for function calculation may be stored in the storage unit 12. One or both of the function expression information and the function parameter information corresponds to the color rendering light intensity information.
(Other embodiments and supplements)

  When the color rendering properties and luminous intensity are controlled by three light sources that emit three primary colors of light as the lighting fixture Lij, three light sources corresponding to the three light sources are displayed in the color rendering light intensity information table shown in FIGS. It is only necessary to provide a column for storing the light intensity value. When using a lighting fixture that uses three light sources of red, green, and blue light-emitting diodes with remarkable improvement in luminous efficiency, the R, G, and B luminous intensity values, the ratio of luminous time, and the like are the color rendering luminous intensity information. Further, it may be represented by three pieces of information, ie, two color difference information and luminance information used in television technology. In the case of a warm light source and a cold light source, the light intensity ratio and the average light intensity of both light sources may be used. In the case of a light source whose color rendering property can be changed with a single light source, the color rendering parameter and luminous intensity value of a format matching the light source are applied as the color rendering luminance information, and the color rendering parameter and luminous intensity value are set and stored. You can do it.

  In the case of using a light source whose color rendering properties also change when the luminous intensity changes, only the luminous intensity information is sufficient instead of the color rendering information and luminous intensity information of a predetermined lighting fixture constituting the color rendering luminance information. This light intensity information is first information that bears both information of light intensity and color rendering properties, and constitutes color rendering light intensity information.

  In each of the above embodiments, a lighting fixture with a fixed luminous intensity may be added. Such a luminaire may be considered an incidental or additional lighting environment for the lighting system of the present invention, or may be considered part of the lighting system of the present invention.

You may make it do. Further, the illumination control device 100 can be configured on a portable information device such as a PDA, a personal computer, a cellular phone, etc., and the illumination can be easily controlled.
