Description of the Related Art Generally, when illuminating an indoor space such as a house or an office or an outdoor space such as a road, a park or a sports facility, a lighting device selected according to the purpose of use is installed in each space. And lighting. Each of these lighting fixtures is equipped with a high-pressure discharge lamp such as a metal halide lamp or a high-pressure mercury lamp, or a light source lamp such as an electrodeless discharge lamp, a fluorescent lamp, an incandescent lamp, or the like that emits light by using electric energy.

[0003]

Since these lamps eventually deteriorate and no longer light up, it is necessary for the user to replace them with new ones each time. The work is often annoying to the user,
Especially, when replacing a light source lamp installed on a high ceiling or a streetlight, a considerably difficult work is involved.

Further, when a user illuminates a space used by a lighting device, there are cases where the user wants to change the lighting atmosphere. In particular, with respect to the lighting of the indoor space, there are many requests to change the lighting atmosphere. However, in a normal lighting fixture, the light color of the lighting cannot be changed unless the lamp itself is replaced. Therefore, it is practically difficult to change the lighting atmosphere variously according to the user's request.

In view of the above problems, the present invention provides an illumination light supply system capable of omitting the user's work of exchanging a light source lamp that has been turned off and allowing the user to obtain illumination light for a long period of time.

The illumination light supply system is managed by a “supplier” that supplies the illumination light to the user, and the supplier replaces the lamp used in the light source unit even when the lamp is not lit. Here, the “supplier” refers to a person, a municipality, a company, or the like that supplies illumination light to the user.

Therefore, even if the user does not replace the lamp of the light source section, the light source section outputs light for a long period of time.
The light transmitted from the light source unit to the user by the light transmitting unit is radiated into the space by the illumination light emitting unit. here,
It is also possible to provide each user with a charging means for requesting the illumination light usage fee. The charging means is provided with a light metering unit that measures the amount of light transmitted to each user by the transmitting unit and a storage unit that stores the cumulative amount of light amount measured by the light metering unit, and stores it in the storage device. An amount corresponding to the accumulated amount may be charged to each user as an illumination light usage fee. In this case, the supplier is paid a fee according to the cumulative amount of illumination light used by the user.

In order to achieve the above-mentioned object, the present invention provides, in an illumination light supply system, two or more light source units that respectively generate and output light of different colors, and each color output from each light source unit. A light mixing unit that mixes light, an adjusting unit that adjusts the amount of each color light supplied from each light source unit to the light mixing unit, and the light mixed by the light mixing unit is transmitted to one or more users.

phere) 12 and is configured. The integrating sphere is generally used to measure diffuse reflectance or transmittance of an object, but here, as described below,
Used to mix and split light.

Each of the light emitting parts 11 (11R, 11G, 11B), for example, as shown in FIG. 3, a light emitting lamp 111, a drive circuit 112 for driving the light emitting lamp 111, and light emission. It is composed of a condenser 113 that collects the light emitted from the lamp and sends it to the entrance window 13 of the integrating sphere 12. Here, as the condenser 113, a reflector (reflector) may be used as shown in FIG. 3, or a condenser may be combined with the reflector.
You may use only a condensing lens.

As the light emitting lamp 111, fluorescent lamps of R, G and B colors can be used. The integrating sphere 12 is
It is a hollow sphere whose inner surface is coated with a white diffusing material, and has a plurality of entrance window portions 13 and a plurality of exit window portions 14. Then, as shown in FIG. 2, the light emitting portions 11R, 11G, and 11B are attached to the three entrance window portions 13 of the integrating sphere 12.

In the above light source section 10, each light emitting section 11
The light generated by R, 11G, and 11B is incident on each incident window portion 13
Enters the integrating sphere 12 from and is diffused and mixed in the integrating sphere 12 to become white light, which is branched and emitted from each emission window portion 14 into the first optical transmission path and the second optical transmission path. Note that FIG.
Then, in the light source unit 10, the lights from the light emitting units of three colors are mixed, but the light emitting unit 11 of one color may be used alone, or a plurality of the light emitting units 11 of the same color may be used.
As the light emitting lamp, a high pressure discharge lamp such as a metal halide lamp or a high pressure mercury lamp, an electrodeless discharge lamp, or an incandescent lamp can be used.

When the light source section 10 is provided with a plurality of light emitting sections of the same color, the light output of the light source section 10 can be changed by changing the number of lights. Hereinafter, the optical cables 21 and 22, the illumination light emitting section 30,
The light metering device 40 and the like will be described. This description is common to the first optical transmission path and the second optical transmission path.

The optical cables 21 and 22 and the illumination light emitting section 3
Regarding 0: As the optical cables 21 and 22, it is possible to use optical fiber cables in which a large number of optical fibers made of glass (for example, quartz glass) having high transmittance are bundled.
However, in addition to this, a hollow light pipe or a light duct may be used. FIG. 4 is a diagram showing a specific example of the illumination light emitting section 30.

The illumination light emitting section 30 includes an optical cable 22.
The light diffusing medium 31 and the reflecting mirror 32 are connected to the emission end of the. The light diffusion medium 31 is a semitransparent resin rod, receives light from the optical cable 22, and radiates it as illumination light to the surroundings. The reflecting mirror 32 reflects the illumination light emitted from the light diffusion medium 31 toward the room space. Thereby, the light transmitted via the optical cables 21 and 22 is efficiently radiated to the room space as illumination light.

Structure of Light Quantity Adjusting Section 60: FIG. 5 is a diagram showing the structure of the light quantity adjusting section 60. In this illumination light supply system, as shown in FIG. 5, the light quantity adjusting unit 60 is directly attached to the light source unit 10. That is, the light quantity adjusting units 60 are attached to the two emission window portions 14 of the integrating sphere 12, respectively.

In this light quantity adjusting section 60, the exit window section 1
4 and the incident end 21a of the optical cable 21 are opposed to each other with a gap 61 therebetween. Here, the tip portion 14a is provided with a condenser lens for condensing the light emitted from the emission window portion 14 to the incident end portion 21a, and the light flux emitted from the emission window portion 14 passes through the gap 61. After passing, it is taken into the optical cable 21.

In addition, the light quantity adjusting section 60 includes a shield reflector 6
2 and a drive unit 63 for inserting and withdrawing the shield reflection plate 62 into and from the gap 61. The extent to which the shield reflection plate 62 is inserted into the gap 61 is adjusted by the drive unit 63. It is possible. Further, the surface of the shield reflection plate 62 facing the tip portion 14a is mirror-finished.

In the light quantity adjusting section 60 shown in FIG. 5, only one shield reflection plate 62 is drawn for convenience, but a plurality of shield reflection plates are arranged in an annular shape like a diaphragm mechanism of a camera. It is desirable to configure the light quantity adjusting unit 60. In the light quantity adjusting unit 60, the degree of inserting the shield reflection plate 62 into the gap 61 is adjusted as described below so that the light flux emitted from the emission window portion 14 into the gap 61 is incident on the optical cable 21. It is possible to adjust the ratio (aperture) of the luminous flux that is generated.

That is, in the state where the shield reflection plate 62 is not inserted into the gap 61 at all (opening degree 100%), the entire light flux emitted from the emission window portion 14 into the gap 61 enters the optical cable 21. When the shield reflection plate 81 is completely inserted into the gap 61 (opening degree 0%), all the light flux emitted from the emission window portion 14 is reflected by the shield reflection plate 62 and returned to the inside of the integrating sphere 12 again. It is collected and used as the output of the light source unit 10.

Further, when the shield reflection plate 62 is partially inserted in the gap 61, a part of the light flux emitted from the emission window portion 14 is reflected by the shield reflection plate 62 and is directed toward the integrating sphere 12. And the rest is taken into the optical cable 21. The exit window portion 14 of the integrating sphere 12 and the light quantity adjusting portion 60
May be connected via an optical cable. However, when the light quantity adjusting unit 60 is directly attached to the emission window unit 14 as described above, the light from the light source unit 10 is reflected by the shielding reflection plate 62 and the integrating sphere. It is desirable in that the loss of light energy during returning to 12 is small.

The drive unit 63 operates by an ON / OFF signal sent from the input unit 70. When the signal is ON, the shield reflection plate 62 is inserted into the gap 61, and when the signal is OFF, the shield reflection plate 62 is inserted into the gap 61. Pull out from. As a result, the illumination light emitted from the illumination light emitting unit 30 is turned ON / OFF based on the ON / OFF instruction given to the input unit 70 by the user.

In addition, the amount of light emitted from the illumination light emitting section 30 can be adjusted (dimming) based on the user's request as follows. Illumination light providing device 10
The second input unit 70 allows not only ON / OFF but also the amount of light to be emitted from the illumination light emitting unit 30, and sends the instructed light amount value to the light amount adjusting unit 60.
Further, the light quantity measurement values measured by the light metering device 40 are sequentially transmitted to the light quantity adjustment unit 60, and the light quantity adjustment unit 60 matches the light quantity measurement values with the instruction light quantity values sent from the input unit 70. Control the aperture.

In the light quantity adjusting unit 60, the gap 61
Even if an ND filter (Neutral Density Filter) is inserted in the above, dimming is possible. However, when the shield reflection plate 62 is inserted as described above, the reflected light can be collected and used, whereas when the ND filter is inserted, the light is absorbed and not collected and used.

Structure of light metering device 40: Light metering device 40
Measures the amount of light (luminous flux amount) supplied to the illumination light emitting unit 30 in real time, and stores the cumulative amount of light in the storage device 50. As shown in FIG. 6, in the light metering device 40, the emitting end 21b of the optical cable 21 and the incident end 22a of the optical cable 22 are arranged opposite to each other with a gap 41 therebetween. Here, the emission end 21b has a condenser lens that condenses the light beam emitted from the optical cable 21 on the incident end 22a, and the light beam emitted from the optical cable 21 has a gap 41.
After passing through, the optical cable 21 is taken in.

A half mirror 42 is provided in the gap 41 so that only a part of the light flux passing through the gap 41 is reflected and made incident on an illuminance meter 43. Generally speaking, a half mirror often refers to one in which light is split so that transmitted light and reflected light are substantially equal to each other. However, as the half mirror 42, transmitted light is more important than reflected light. It is preferable to use the one that splits the light so that a large amount of the light is split, because loss can be reduced.

Illuminance (lx) measured by the illuminance meter 43
Is proportional to the luminous flux amount (lm) sent from the optical cable 21 to the optical cable 22, it is possible to calculate the luminous flux amount from the measurement value of the illuminometer 43. Further, the light metering device 40 is also provided with a timer circuit (not shown) for measuring time, and the illuminance measured by the illuminometer 43 in real time and the integrated value by the illumination light usage time (seconds) measured by the timer circuit. Is stored in the storage device 50. This integrated value corresponds to the cumulative light amount supplied from the light supply device 101 to the illumination light supply device 102.

In the light metering device 40, it is also possible to measure the luminance in real time by using a luminance meter instead of the illuminance meter and measure the luminous flux amount (lm) from the luminance value (cd / m ² ). Is. (Operation of Illumination Light Supply System) In the illumination light supply system, the light source unit 10 of the light supply device 101 constantly generates light. The generated light is ready to be supplied to each illumination light emitting unit 30 via the first optical transmission path and the second optical transmission path.

On the other hand, each user instructs the input unit 70 of the illumination light providing device 102 to turn on when the illumination light is needed, and turns it off when the illumination light is not needed. As a result, the time the user requested
(Until the instruction is made), the light quantity adjusting unit 60 is opened, and accordingly, the illumination light emitting unit 30 emits the illumination light.

The amount of illumination light used by each user is measured by the light metering device 40 corresponding to each user, and the accumulated amount is stored in the storage device 50. The case where one supplier supplies illumination light to two users has been described above with reference to FIGS. 1 and 2. However, one supplier illuminates one user or three or more users respectively. It is also possible to supply light.

(Regarding output control in the light source section 10)
Regarding the amount of light output from the light source unit 10 in the light supply device 101, the output is always constant regardless of the variation in the number of lighting requests (the number of the input units 70 of the entire system that are instructed to be turned on). However, in that case, since a loss occurs, the output of the light source unit 10 is made variable, the number of lighting requests is checked, and the output of the light source unit is increased as the number of lighting requests increases in accordance with the number of lighting requests. You may adjust.

FIG. 7 is a diagram showing an example of an output control method in the light source section 10. In the light source unit 10, 10 light emitting units 11 are provided, and 100 illumination light emitting units 30 are provided in the entire illumination light supply system. To turn on all the 100 illumination light emitting units 30, It is assumed that 10 light emitting units need to be turned on. In this case, the number of lighting requests fluctuates between 0 and 100.

Here, if the output of the light source unit 10 is always kept constant, it is necessary to always turn on 10 light emitting units so as to cover the required light quantity when the number of lighting requests is 100. Therefore, a loss occurs when the number of lighting requests is small. On the other hand, the number of light emitting units in the light source unit 10 can be changed between 1 and 10, and as shown in FIG. 7, when the number of lighting requests is 0 to 9, the number of light emitting units to be lighted is set. 1, when the number of lighting requests is 10 to 19, the number of light emitting units to be turned on is 2, ..., The number of lighting requests is 90 to
When the number of light emitting parts to be turned on is controlled to 10 at 100, it is possible to cover the required light amount at each time, and as compared with the case where the output of the light source part 10 is constant as described above, The loss can be significantly reduced.

(Maintenance of Light Source Section) The maintenance of the light supply device 101 including the light source section 10 is performed by the supplier who manages it. For example, if the light emitting lamp goes out, the supplier repairs or replaces it.
Therefore, the user does not need to perform the troublesome work of replacing the unlit lamp, and can obtain the illumination light for a long time (semi-permanently) and for a necessary time when necessary.

(Charging) Although not shown, the present illumination light supply system is provided with a charging means for periodically charging each user for the usage fee of the illumination light. This charge is performed according to the cumulative amount of illumination light amount stored in the storage device 50 corresponding to each user.

That is, the depreciation of the equipment of the illumination light supply system and the total cost required for operation, maintenance, etc.
It is distributed to each user. In this distribution, the charging amount of each user increases as the cumulative amount of illumination light increases. FIG. 8 shows some specific examples of the charging amount setting method. In the example shown in (a), the billing amount continuously increases in proportion to the cumulative amount of illumination light.

The examples shown in (b) to (d) are common in that a fixed basic fee and a pay-per-use fee that increases according to the cumulative amount of illumination light are added. However, the calculation method of the usage-based usage fee differs as follows. In (b), the pay-per-use fee continuously increases in proportion to the cumulative amount of illumination light. In (c), the amount-of-use fee increases stepwise in proportion to the cumulative amount of illumination light.

In (d), as the cumulative amount of illumination light increases, the usage fee also increases, but the rate of increase decreases. In (e), as the cumulative amount of illumination light increases, the usage fee also increases, and the rate of increase also increases. Each user charged as described above pays the supplier a fee corresponding to the charge amount.

Generally, it is considered desirable to charge according to the cumulative amount of illumination light as described above, but a fixed amount may be charged for each user. [Second Embodiment] FIG. 9 is a block diagram of an illumination light supply system according to the present embodiment. In addition, FIG. 10 is a diagram illustrating a configuration of the illumination light supply system.

In the figure, the same components as those in the first embodiment are designated by the same reference numerals. Also, in FIG.
In FIG. 10, for simplification, it is shown that light is supplied only to the house (illumination light providing device 102) managed by one user. As shown in FIG. 9, the illumination light supply system is
Three light source units 10R, 10G, and 10B that generate and output lights of different colors (R, G, and B) are provided. From each of these light source units 10R, 10G, and 10B, a first optical transmission path and a second optical transmission path are provided. An illumination light is supplied to each room space by being branched into an optical transmission path.

However, the first optical transmission path and the second optical transmission path reach each room provided in one residence owned by one user. That is, the two illumination light providing devices 102 shown in FIG. 9 are provided in a house managed by one user. In the first optical transmission path and the second optical transmission path, a light amount adjusting unit 60 (60R, 6) for adjusting the light amount of each color light output from the light source units 10R, 10G, 10B, respectively.
0G, 60B), a light measuring device 40 for measuring the amount of light
(40R, 40G, 40B), optical cables 21 and 22 as an optical transmission means for transmitting each color light, and each light quantity adjusting unit 60
A light mixing means 80 for mixing the light of which the light amount has been adjusted by, and an optical cable 23 for transmitting the mixed light are provided, and the optical cable 23 reaches an illumination light emitting section 30 which emits light to a room space managed by the user. ing.

In this embodiment, the light transmitted through the first optical transmission path and the second optical transmission path as described above is
Since it is used by one user, the cumulative amount of illumination light measured by the light metering devices 40R, 40G, 40B of the first optical transmission path and the second optical transmission path is stored in one storage device 50. ing. Further, in the present embodiment, as shown in FIG. 9, in addition to the light source units 10R, 10G and 10B, the light amount adjusting units 60R, 60G and 60B, the light metering device 40R,
40G, 40B and the light mixing means 80 are also incorporated in the light supply device 101.

Each of the light source sections 10R, 10G, and 10B is constructed by attaching a light emitting section to the entrance window section of the integrating sphere, like the light source section 10 described in FIG. 2 of the first embodiment. However, only the red light emitting portion is attached to the red light source portion (R), only the green light emitting portion is attached to the green light source portion (G), and only the blue light emitting portion is attached to the blue light source portion (B). . The light mixing means 80 is the integrating sphere 1 described in the first embodiment.
The same integrating sphere as 2 can be used.

In this case, the three incident window portions of the integrating sphere and the light measuring devices 40R, 40G and 40B are connected to the optical cable 22.
Connect with. Then, the exit window of the integrating sphere and the illumination light emitting section 30 are connected by the optical cable 23. With the above configuration, the color lights from the light source units 10R, 10G, and 10B are mixed by the light mixing unit 80, reach the illumination light emitting unit 30 via the optical cable 23, and are emitted to the room space.

Here, as described below, by adjusting the light quantity of each color light sent to the light mixing means 80 by the light quantity adjusting section 60, the illumination light emitted from the illumination light emitting section 30 can be adjusted in color. It is like this. (Regarding color adjustment of illumination light) The light amount adjustment of each color light in the light amount adjustment unit 60 is performed as follows according to the "illumination environment" required by the user.

Generally, the "lighting environment" is a color temperature,
There are light intensity, average color rendering index (Ra), and the like, but here, the case of adjusting the illumination environment to the color temperature desired by the user will be described. In the input unit 70, the user turns ON /
It is assumed that the "color temperature" can be instructed as the lighting environment together with turning off.

The input section 70 is an information transmission means (for the information transmission means described in the first embodiment) for transmitting the "illumination environment information" together with the ON / OFF signal based on the instruction from the user. Similarly, it is transmitted to the light supply device 101 via a dedicated wiring, wireless, telephone line, Internet, etc. The light supply device 101 includes the light amount adjusting units 60R and 60R.
A calculation unit 71 that calculates a light amount instruction value used when the G and 60B adjust the light amount is provided. This calculator 71
On the basis of the illumination environment information sent from the input unit 70, the light mixing units 80 from the light source units 10R, 10G, and 10B.
Calculate the amount of light to be sent to. This light amount calculation is performed, for example,
From the three light source units 10R, 10G, 10B to the light mixing unit 80
If the relationship between the ratio of the amount of light to be sent to and the illumination environment obtained at that time is investigated and stored in the calculation unit 71 as a correspondence table, the correspondence table can be referred to.

Then, the light quantity calculated by the calculation unit 71 is
Each light quantity adjusting unit 60R, 60G, 60B as a light quantity instruction value
Sent to. In the light amount adjusting units 60R, 60G, 60B,
It opens and closes based on the ON / OFF signal from the input unit 70, and the light amount sent from each of the light source units 10R, 10G, and 10B to the light mixing unit 80 matches the light amount instruction value sent from the calculation unit 71. Adjust the aperture.

Hereinafter, the calculation section 71 and the light quantity adjusting section 60R,
The dimming operation in 60G and 60B will be specifically described. In the input unit 70, as the “lighting environment”, 3
It is assumed that the color temperature of 000K, 5000K, or 6700K can be designated. Table 1 below
Is an example of a correspondence table showing a relationship between a light amount ratio of RGB color lights and a color temperature.

[0057]

[Table 1] In Table 1, if the amount of light sent from the light source units 10R, 10G, and 10B to the light mixing unit 80 is set to the ratio shown in this table, each color temperature (3000K, 5000K, 6700K) is obtained.
Is obtained and is stored in the calculation unit 71.

The calculator 71 calculates the illumination environment information (3000K, 5000K, 6700K) sent from the input unit 70.
Based on either of the above), the light amount ratio to be sent from the light source units 10R, 10G, and 10B to the light mixing unit 80 is calculated by referring to the corresponding table. For example, when the illumination environment information sent from the input unit 70 is “5000K”, the calculation unit 71 refers to Table 1 and refers to the light amount adjustment unit 60.
“Light amount instruction value = 0.27” for R, light amount adjusting unit 60
“Light amount instruction value = 0.61” for G, light amount adjusting unit 60
"Instruction value of light amount = 0.12" is sent to G.

In the light quantity adjusting units 60R, 60G and 60B, the light mixing units 8 are connected from the light source units 10R, 10G and 10B.
The amount of light sent to 0 is set to each light amount instruction value (0.27, 0.61,
0.12). As a result, the light mixing unit 80 generates light whose color temperature is adjusted to 5000K. The toned light is sent to the illumination light providing device 102 via the optical cable 23, and the illumination light emitting unit 30
Will be emitted from.

It should be noted that the above-mentioned light amount instruction value is obtained by each light source unit 10.
Although the total amount of light sent from the R, 10G, and 10B to the light mixing unit 80 is set to 1, the light emitted from the illuminating light emitting unit 30 together with the color temperature is set as follows. The amount of illumination light will also be adjusted. Input section 7
In 0, as the "illumination environment information", in addition to the "color temperature", the required "illumination light amount X" can be designated.
