Abstract

PROBLEM TO BE SOLVED: To provide a lighting system having correlation with the change of the quantity of light of sunlight, capable of adjusting organism rhythm, and easily maintaining awakening. SOLUTION: A light receiving part 1 generates a voltage signal having correlation with (proportion to) the quality of light of sunlight. A comparison part 7 of a power control part 2 outputs a control signal of 'H' when reference voltage V0 of a reference wave form generating part 6 is higher than a voltage signal sent from the light receiving part 1. A lighting device 4 sets the lighting power (dimmer degree) of a luminescent load 5 according to the width of the control signal. The lighting device 4 sets lighting power supplied to the luminescent load 5 so that illuminance within a room which a luminescent object varies in proportion to the variation of the receiving quantity of light from sunlight (outside light) according to the width of the input control signal. Or, when the receiving quantity of light is decreased and the width of the control signal is increased, lighting power is decreased and brightness is decreased, and oppositely, when the receiving quantity of light is increased and the width of the control signal is decreased, lighting power is increased and brightness is increased.

Description

[0001]
BACKGROUND OF THE INVENTION
  The present inventionIndoorThe present invention relates to a lighting system.
[0002]
[Prior art]
  There are the following four fields that require illumination conditions that have a correlation with external light.
[0003]
  The first field is adjustment of biological rhythm (internal clock). It is known that the human body has a biological clock, and the natural period of the biological clock is about one hour longer than 24 hours a day. Thus, for example, a dark roomOrAlways under constant lightingandA human being who has no clue of time cannot adjust the time of the biological clock, and the time of the biological clock is delayed each time the day is compared with the time of the clock in actual life. In order to adjust the body clock to 24 hours a day, it is necessary to adjust the clock so that the clock is advanced for about 1 hour a day. It is known that stimulation of light (especially bright light) is effective in correcting the time of the body clock. In normal life according to the natural environment, humans mainly adjust the time of the biological clock by stimulating changes in sunlight.GoingIt is.
[0004]
  By the way, if the biological rhythm (internal clock) cannot be adjusted properly, various modulations are made to the mind and body.ComeIt is known. Understanding that many people experienceeasyAs an example, a jet lag symptom can be given as an abnormality caused by the difference between the time of the body clock and the time of actual life. In addition, the lack of light necessary to adjust the body clock causes abnormal biological rhythms.ComeSeasonal affective disorder (winter depression) may develop. There is also a theory that lack of light promotes weakening of biological rhythm due to aging, leading to sleep disorder and dementia symptoms of elderly people, day / night reversal abnormal behavior and nighttime habits. Can't get up in the morning,OrThere are reports that children who cannot attend school often have abnormal biological rhythms.
[0005]
  Eliminates such abnormal biological rhythm (internal clock)OrIt is known that a method using light (high illuminance light) is effective for prevention, and a device that illuminates the eyeball with light attached to the human body or a lighting fixture arranged in a panel shape, A device that provides a high-intensity light source for illuminating a light source has been developed. With low illuminationandPlaces where constant conditions are assumed include hospitals, nursing homes, underground malls, etc. In these places, bright light is necessary to adjust biological rhythms (internal clocks), and at the same time targeting a large number of people Dimming is considered necessary.Furthermore,When dimming for the purpose of biological rhythm adjustment in these places, it is considered effective to restore or maintain the natural rhythm if the dimming has a correlation with external light (sunlight).
[0006]
  The second area is the maintenance of arousal by bright light in the daytime.OrIt can be raised. In general, it is known that when a light stimulus is received by a retina, secretion of a hormone called melatonin, which is said to induce sleepiness, is suppressed. It is also known that the activity of the sympathetic nervous system is enhanced by light stimulation, and as a result, the arousal level is improved. Such awakening maintenance effect by light tends to increase as the illuminance increases.
[0007]
  stillIn the same way, even with bright light stimulation, the illuminance changes more than the constant illuminance continues for a long timeShakeIt is known that the effect of maintaining arousal is higher when there is a gap. In particular, it is more effective to reduce the change rate when the illuminance falls and increase the change rate when the illuminance rises.
[0008]
  Now, it is known that the degree of awakening during the day is usually maintained at a higher level than at night, but changes with time even during the day and shows several peaks and valleys. Among them, the decrease in arousal level during the day is significant in the first half of the afternoon (corresponding to the time zone after lunch), but it is known that the arousal level changes regardless of whether or not lunch is taken. . Although the degree of change in arousal level varies from person to person, if the decrease in arousal level during the day is large, it is considered that taking a rest once during the valley time will increase the work efficiency thereafter. . Offices, factories, schools, underground shopping areas, etc. are expected to be used for such awakening maintenance by light.AhI can get lost.
[0009]
  As the third field, sunshine is not incorporatedOrA follow-up type device called “Himawari” is known as one that provides the same effects as sunshine in a deficient living environment. This device is intended to introduce sunlight into the living environment using an optical fiber.
[0010]
  As the fourth field, the use of light related to lighting at windows in stores, offices and factories is known. In the case of store lighting, it is generally said that it is effective to brighten the lighting at the window in the store when the outside light becomes strong. This is because if the difference in illuminance between the outside world and the window increases, the store will feel dark. To avoid this adverse effect, turn on many lights at the window when the outside is brightaboutIs lineNaIt has been broken. Also, if the side of the room is a large amount of light in a room where a normal person is present, such as an office or factory, the brightness contrast between the person or object in the room and the background window surface is large and appropriate in the daytime, especially in fine weather. Can't keep up. In order to avoid such adverse effects, it is said that it is effective to make the ceiling lighting near the window brighter than the ceiling lighting at the center of the room when the outside is bright.
[0011]
  Note that the illuminance measurement position is ideal for facial illuminance, but accurate measurement is difficult, so as a normal substitute characteristic, a point 1.2 m high from the floor (sitting on a chair)WhenThe vertical illuminance at the eyeball position) was used. The illuminance that appears in the following description is also measured at this position. The illuminance as a standard necessary for normal work or the like means horizontal illuminance on the desk surface (as a standard necessary for work or the like). In general, the relationship between both illuminances in a normal room is that the horizontal illuminance is about 1.5 times the vertical illuminance.
[0012]
[Problems to be solved by the invention]
  By the way, the above four fields generally have a problem that there is no lighting system that is automatically dimmed and controlled so as to have a correlation with outside light.
[0013]
  In other words, the existing lighting device that can be used in the first field is a small-sized one for personal use, and there is a problem that it is troublesome to attach / detach and control on / off.More, Low illuminance with respect to illuminance environmentandWhen trying to adjust biological rhythms in places such as hospitals, nursing homes, underground malls, etc. where constant conditions are assumed, many existing small devices require a large number of units.andA lot of manpower is required for attachment / detachment and on / off control, which is not practical.
[0014]
  Also, existing lighting devices that can be used in the second field have not yet been realized. In addition, the device called “Sunflower”, which is the prior art in the third field, has a very large facility, resulting in a large cost. However, there is a problem that the amount of light obtained by the optical fiber is less than that of general indoor lighting. there were.
[0015]
  In the fourth field, there is a problem that dimming cannot be performed automatically in multiple stages because light is dimmed by manually changing the number and types of lighting at the window.
[0016]
  Furthermore,In order to have practicality as indoor lighting, the problem of securing the minimum amount of power, the problem of preparing a separate power source to secure the minimum amount of power regardless of outside light, power Since the power having a correlation with the external light cannot be obtained if the power is always controlled to the setting level, the selection of the state in which the power is controlled to the setting level or the state having the correlation with the external light can be switched as necessary. The problem of making it possible to divide the lighting device that receives the supply of power having a correlation with the external light and the lighting device that receives the supply of the power not related to the external light, and has a correlation with the external light in a necessary part of the room Make it possible to set the brightness required for room lighting to different levels according to the time, such as darkening during nighttime sleep and brightening during daytime activities. There is a problem and so to say.
[0017]
  Practicality in such lighting systemsMoreIf you want, make your equipment smaller and provide a rational system so that you don't have to rely on commercial power using sunlight,OrThe problem of using sunlight to save commercial power consumption and making it a reasonable amount, the power correlated with outside light reacts directly to fine fluctuations in outside light, for example, clouds cross the sun If it changes, the brightness of the room lighting will frequentlyandThe problem is not to change with a small time constant so that there is no such problem, because it may not only affect the indoor life and adversely affect the eyes. There is.
[0018]
  Next, problems specific to each application field include the following.
[0019]
  In the first field of use for adjusting biological rhythms, the brightness is sharpened day and night so that it is bright during the day and dark at night, and the change in illuminance does not become abrupt when switching between day and night. There is a problem of using morning light with particular emphasis on illuminance changes that correlate with external light.
[0020]
  In the second field of use that aims to maintain arousal with bright light,ShakeGigHoldingAs a result, the problem of improving the awakening maintenance effect more than just bright light, the problem of changing the illuminance change rate from light → dark to dark → less than light, the problem of preventing the illuminance change from becoming regular and monotonous The illumination control is divided into basic illumination and task illumination, and there is a problem of performing appropriate control according to the individual state by the task illumination.
[0021]
  In the third field of use for the purpose of supplementing the living environment, which tends to be lacking in sunlight, there is a problem of incorporating as much light as possible into the room in lighting having a correlation with outside light.
[0022]
  In the field of use aiming at illuminance correction in the fourth window-side illumination, an illumination having a correlation with outside light is arranged near the window to correct the room illuminance correction.DoHowever, there is a problem of having a correlation with external light incident from the window.
[0023]
  The present invention has been made for the purpose of solving the above-described problems., Can adjust the biological rhythm, and can maintain the wakefulness by suppressing the decline of wakefulness during the dayProvide lighting systemThere is.
[0024]

DETAILED DESCRIPTION OF THE INVENTION
(Basic form1)
  Figure 1 shows a bookBasic formIndicates a bookBasic formReceives solar light and outputs a signal having a correlation with the amount of light, for example, a solar cellOrA light receiving unit 1 composed of a light receiving element such as CdS, and a power control unit 2 that outputs a control signal for lighting the illumination load 5 with lighting power connected to the light receiving unit 1 and correlated with the output signal of the light receiving unit 1; The lighting device 6 includes a lighting device 6 for continuously dimming and lighting the lighting load 5 with lighting power corresponding to a control signal from the power control unit 2, and a power supply unit 3 that supplies power to the lighting load 5 through the lighting device 4.
[0032]
  Lighting load 5 is thisBasic form(Others described belowBasic formHowever, in the same manner, a discharge lamp load such as a fluorescent lamp is used, and in response to this, the lighting device 4 varies the oscillation frequency according to the width of the control signal from the outside to change the impedance for the ballast, and the lighting power An inverter device having a continuous dimming function for controlling (lamp current) is used. When the incandescent lamp or halogen lamp is an illumination load, a light control device is used that controls the lighting power by phase control or the like according to the width of the control signal from the outside.Of courseA lighting device other than such a method may be used. The power supply unit 3 uses a unit that supplies DC power to the lighting device 4 that is an inverter device.
[0033]
  Next bookBasic formWill be described in detail.
[0034]
  The light receiving unit 1 outputs a voltage signal having a correlation (proportionality) with the amount of sunlight, to the power control unit 2. The power control unit 2 includes a comparison unit 7 that compares a reference voltage signal having a triangular waveform with a predetermined frequency generated by the reference waveform generation unit 6 and a voltage signal from the light receiving unit 1, and the comparison unit 7 is shown in FIG. The reference voltage signal V of the reference waveform generator 6 shown in FIG.₀  Is the voltage signal V from the light receiving unit 1₁When it is higher than that, an "H" output is output as shown in FIG. 2B, and when it is opposite, an "L" output is output. That is, a control signal having a small signal width is generated when the amount of received light of sunlight is increased, and a control signal “H” having a large signal width is generated and output to the lighting device 4.
[0035]
  The lighting device 4 illuminates the room to be illuminated (for example, the illuminance on the desk surface) in proportion to the change in the amount of light received from the sun (external light) shown in FIG. Is set to the lighting power supplied to the illumination load 5 so as to change as shown in FIG. In other words, when the amount of received light decreases and the width of the control signal increases, the lighting device 4 decreases the lighting power accordingly to reduce the light output of the illumination load 5 and reduce the illuminance in the illumination area. Conversely, when the amount of received light increases and the width of the control signal decreases, the lighting power is increased to increase the light output of the illumination load 5 and increase the illuminance of the illumination area.
(Basic form2)
  Figure 4 shows the bookBasic formIndicates a bookBasic formAs shown in the figure, the light receiving unit 1 that receives sunlight and outputs a signal correlated with the amount of light, and the lighting load 5 connected to the light receiving unit 1 with lighting power correlated with the output signal of the light receiving unit 1. The power control unit 2 that outputs a control signal for lighting, the lighting device 4 that continuously dims the lighting load 5 with the lighting power corresponding to the control signal of the power control unit 2, and the lighting load 5 through the lighting device 4 And a power supply unit 3 for supplying power to the lighting load 5 and a power level setting unit 8 for presetting a lower limit level of the lighting power of the lighting load 5. BookBasic formThen, the light receiving unit 1, the lighting device 4, the illumination load 5, and the power supply unit 3 areBasic form1 is used.
[0036]
  Next bookBasic formWill be described in detail.
[0037]
  The light receiving unit 1Basic formSimilar to 1, a voltage signal having a correlation (proportional) with the amount of sunlight is generated. The power control unit 2 includes a comparison unit 7 that compares a reference voltage signal having a predetermined triangular waveform generated by the reference waveform generation unit 6 and a voltage signal from the light receiving unit 1, and the comparison unit 7 includes the reference waveform generation unit. 6 reference voltage V₀  Is the voltage signal V from the light receiving unit 1₁When it is higher than that, the comparison section 7 outputs an “H” output, and when it is the opposite, outputs an “L” output (see FIGS. 2A and 2B). The control signal constituted by “H” output is input to the AND circuit 9 together with the setting signal output from the power level setting unit 8 and the logical product is obtained.TakeIt is done.
[0038]
  The power level setting unit 8 includes a reference waveform generation unit 10, a setting unit 11 including, for example, a volume 12 and a reference voltage source 13 for setting a lower limit power level, and a comparison unit 14. Similar to the reference waveform generation unit 6 of the control unit 2, a reference voltage signal having a triangular waveform is output. The comparison unit 14 compares the reference voltage signal with the output voltage of the setting unit 11, and the reference waveform generation unit 10 reference voltage signal is obtained. When the output voltage of the setting unit 11 is exceeded, an “H” signal is output. It is assumed that the reference waveform generators 6 and 10 are synchronized and output a reference voltage signal having the same waveform.
[0039]
  Therefore, when the width of the output signal of the comparison unit 7 is smaller than the width of the output signal of the comparison unit 14, the output signal of the comparison unit 7 is output to the lighting device 4 as a control signal, and the width of the output signal of the comparison unit 7 is When it becomes larger than the width of the output signal of the comparison unit 14, the output signal of the comparison unit 14 is output to the lighting device 4 as a control signal. That is, when the amount of light received by the light receiving unit 1 decreases and the width of the output signal of the comparison unit 7 becomes larger than the width of the output signal of the comparison unit 14, the width of the control signal is fixed to the width of the output signal of the comparison unit 14. . Therefore, the lower limit level of the lighting power is set by the width of the output signal of the comparison unit 14.
[0040]
  BookBasic formIn the lighting device 4, the illuminance in the room to be illuminated (for example, the illuminance on the desk surface) in proportion to the change in the amount of light received from the sun (external light) shown in FIG. Is set to the lighting power supplied to the illumination load 5 so as to change as shown in FIG. That is, when the amount of received light is small, the lighting power is reduced to lower the illuminance, and conversely, when the amount of received light is increased, the lighting power is increased to increase the illuminance. If the amount of light received by the light receiving unit 1 is below a certain level, the minimum required illuminance is secured by fixing the illuminance at a preset lower limit level.
(Basic form3)
  Figure 6 shows the bookBasic formShows the book as shownBasic formThen, as a power supply source for supplying lighting power to the lighting load 5 through the lighting device 4, a backflow prevention diode D is used.₂A power supply unit 3 composed of a solar cell having an output terminal connected to the power input terminal of the lighting device 4, a current limiting circuit 16, and a backflow prevention diode D₁And a standby power supply unit 15 composed of a rectifier and a commercial power source having an output terminal connected to a power source input terminal of the lighting device 4.
[0041]
  Also, the power input terminal of the lighting device 4VoltageIs provided with a power level setting unit 20 including a level adjuster 17, a reference waveform generation unit 18, and a comparison unit 19. The lighting device 4 receives the control signals from the power level setting unit 20 and the power control unit 2 and controls the lighting power of the lighting load 5 so that the lighting load 5 is dimmed.
[0042]
  The power control unit 2Basic formLike the ones 1 and 2, the output of the light receiving unit 1 is received and a control signal having a width correlated with the amount of sunlight is output, and the internal configuration is omitted in FIG.
[0043]
  The reference waveform generator 18 of the power level setting unit 20 outputs a reference voltage having a triangular waveform similar to that of the reference waveform generator 6 of the power controller 2.
[0044]
  Next bookBasic formWill be described in detail.
[0045]
  Thus, during operation of the system, power is supplied from the power supply unit 3 and the standby power supply unit 15 to the lighting device 4.NaHowever, when the lighting power increases, the burden on the standby power supply unit 15 also increases.
[0046]
  Since the standby power supply unit 15 has an auxiliary role of the power control unit 2 and its power capacity is small and the lighting power of the lighting device 4 increases and the burden increases, the output current increases, but the current limit The circuit 16 receives the current limit. As a result, the burden on the power supply unit 3 side increases, but the power that can be supplied by the power supply unit 3 is limited.WhenWhen the lighting power is larger than the power combined with the power that can be supplied by the reserve power supply unit 15, the input voltage of the lighting device 4 that is a load is lowered due to an overload state.
[0047]
  On the other hand, the power level setting unit 20 inputs the input voltage of the lighting device 4 to the level adjuster 17 to generate a voltage corresponding to the voltage level corresponding to the voltage, and this voltage and the reference voltage output from the reference waveform generating unit 18. And the comparison unit 19 outputs a control signal similar to that of the power control unit 2, and when the input voltage of the lighting device 4 decreases as described above, the control signal is accordingly accompanied. The width of becomes larger.
[0048]
  The control signal of the power level setting unit 20 is logically ORed with the control signal from the power control unit 2 by the OR circuit 48 and is input to the lighting device 4. Even when the width of the control signal output from the power control unit 2 increases and the input voltage of the lighting device 4 decreases due to an overload as described above, the width of the control signal of the power level setting unit 20 Becomes larger than the width of the control signal output from the power control unit 2, and the lighting device 4 operates in a direction to reduce the lighting power in response to the control signal. That is, the lighting power is controlled so that the lighting load 5 is turned on with the lighting power corresponding to the maximum power that can be supplied by the power supply unit 3 and the standby power supply unit 15 at present.
(Basic form4)
  Figure 7 shows a bookBasic formShows the bookBasic formAs shown in the drawing, the light receiving unit 1 receives sunlight and outputs a signal correlated with the amount of light, and the lighting load 5 is connected to the light receiving unit 1 and the lighting power is correlated with the output signal of the light receiving unit 1. A power control unit 2 that outputs a control signal for lighting, a lighting device 4 such as a dimming lighting device that lights the lighting load 5 with lighting power corresponding to the control signal of the power control unit 2, and the lighting device 4 And a power supply unit 3 for supplying power to the lighting load 5 through, and a backup power supply unit 15, and the output of the backup power supply unit 15 is connected to a backflow prevention diode D.₁And switch SW₁To the power input terminal of the lighting device 4 and the output of the power supply unit 3 to the backflow prevention diode D₂Is connected to the power input terminal of the lighting device 4.
[0049]
  Here, the configuration of the light receiving unit 1, the lighting device 4, the illumination load 5, and the power supply unit 3 is as follows.Basic form1 and the configuration of the standby power supply unit 15 is as follows.Basic form3 is assumed. The power control unit 2 connects the output terminal of the comparison unit 7 to the two-contact changeover switch SW.₂Is connected to one fixed contact a of the switch SW₂When the movable contact is connected to the fixed contact a, the control signal output from the comparison unit 7 is input to the signal input terminal of the lighting device 4 and the changeover switch SW.₂When the movable contact is connected to the fixed contact b, the control signal output from the comparison unit 7 is not output to the lighting device 4, and the signal input terminal of the lighting device 4 is connected to the ground.
[0050]
  Switch SW₁And selector switch SW₂Is linked to the switch SW₁When the switch is on, the selector switch SW₂The movable contact is connected to the fixed contact b side and the switch SW₁When the switch is off, the changeover switch SW₂The movable contact is connected to the fixed contact a side.
[0051]
  Next bookBasic formWill be described in detail.
[0052]
  First switch SW₁When is turned off, the output terminal of the power control unit 2 is connected to the signal input terminal of the lighting device 4. in this caseBasic formThe circuit configuration is the same as 1 and the same operation is performed. The operation explanation in this case isBasic formSince it is the same as 1, description is abbreviate | omitted.
[0053]
  Then switch SW₁When is turned on, the changeover switch SW is interlocked₂The movable contact is connected to the fixed contact b side, so that the signal input terminal of the lighting device 4 is at the “L” level. That is, the width of the control signal becomes zero, and the lighting device 4 turns on the illumination load 5 completely. In this case, power is supplied from the power supply unit 3 and the standby power supply unit 15, and the lighting load 5 is fully lit.sufficientPower supply will be made.
[0054]
  That is, bookBasic formAccording to the switch SW₁Can be realized by turning off the switch SW₁By turning on, it is possible to configure a system in which the user can select the full lighting mode regardless of outside light.

  Therefore, the bookBasic formThen, the illuminance correlated with the amount of sunlight obtained by the system of the frame X is superimposed on the basis of the constant illuminance due to the lighting of the illumination load 5 ′ of the frame Y. System in frame XofThe arrangement of the illumination load 5 that is lit by the lighting device 4 and the illumination load 5 ′ that is lit by the constant illuminance lighting device 47 in the frame Y can be separated.

To do.
[0127]
  Simultaneously with the above dimming control, the remote control signal light receiving unit 72a sends the irradiation direction information determined from the reception channel to the corresponding local illumination direction control unit 55a of the local lighting fixture 50a, and the local illumination irradiation direction control unit 55a Based on the irradiation direction information from the remote control signal light receiving unit 72a, the rotation direction of the motors MT1 and MT2 is controlled so as to irradiate the illumination user M with the required illuminance to change the irradiation direction of the local lighting fixture 50a.
[0128]
  As the local lighting fixtures 50a used in the present embodiment, downlight type lighting fixtures shown in FIGS. 37A to 37D having substantially the same configuration as that of FIG. 34 are used. 34 is different from the local lighting fixture 50a of FIG. 34 in that a remote control light receiving portion 72 is provided in the housing 66, and a signal line 73 from the remote control light receiving portion 72 is provided. Is led out from the upper part of the external fixture holding unit 64 so as to be sent to the corresponding local illumination irradiation direction control unit 63. Since the other configuration is the same as the configuration of FIG. 34, the same components are denoted by the same numbers and symbols, and description thereof is omitted.
[0129]
  Then, the local illumination irradiation direction control unit 55a, which has received the irradiation direction information from the remote control signal light receiving units 54a, performs rotation control of the motors MT1, MT2 to determine the direction and irradiation angle of the lamp 67.Embodiment 5As in the case of, variably set. As described above, in the present embodiment, the illumination user M himself selects the irradiation direction so as to irradiate only the field of view of the illumination user M who is working, and changes the irradiation direction of the local lighting fixtures 50a. By doing so, even if the lighting user M is working at a position different from the previous one, the brightness (illuminance) in the visual field of the lighting user M is changed in the amount of sunlight from sunrise to sunset. While changing so as to correspond to the transition, it is possible to set the illuminance to be higher than the average illuminance in the morning or afternoon at least during a predetermined period after noon.
[0130]
  In the above configuration, the information transmitted from the remote control transmitter 71 is irradiation direction information indicating a preset irradiation direction, but an operation signal for remotely operating the movement of the local lighting device 50a...

Is transmitted from the remote control transmitter 71 as irradiation direction information, the irradiation direction can be set in an optimum direction by the operation of the illumination user M itself.
(Embodiment7)
  This embodiment is used between awakening in the morning and going out for the purpose of work, etc., and a washroom or dining room that is required to wake up a person to use so that it becomes active immediately after going out A space that is required to adjust the biological rhythm of the person to be used according to the purpose, such as a living room where the person to be used is in a relaxed state before falling asleep. It is a lighting system suitable for residential lighting.
[0131]
  As shown in FIG. 38, the lighting system of the present embodiment includes one or more lighting fixtures 80 that can irradiate the visual field of a lighting user M installed in a washroom 74, and dimming those lighting fixtures 80. A lighting device 51 having a function to control, a timer for creating data for changing the light amount of the lighting fixture 80 so as to correspond to the change in the light amount of sunlight from sunrise to sunset, or the brightness of external light A light amount change information generating unit 56 that outputs light amount change information that correlates with changes in the amount of sunlight light, and generates light control data by receiving the light amount change information as control data A control unit 54 that sends the lighting device 51 and a power supply unit 55 are included.
[0132]
  In this embodiment, when the lighting switch SW is turned on, the control unit 54 sends control data to the lighting device 51 based on the light amount change information obtained from the light amount change information generating unit 56, and the lighting device 51 uses the control data as the control data. Based on this, light control is performed so that the light quantity of the luminaire 80 becomes the target light quantity, and the human field of view to be used is irradiated with the illumination light of the luminaire 80. However, the luminaire 80 of the present embodiment covers the light source with a milky panel that diffuses light so that unpleasant glare is not felt even when the luminaire 80 is directly viewed in a state where the maximum amount of light is irradiated.
[0133]
  Usually, the washroom 74 is in a position where it is difficult for sunlight to enter in the house, so there is not enough light to raise the awakening level. Therefore, even if it enters the washroom 74 for washing the face, adjusting the hair, etc., the awakening level is almost the same as the state after the occurrence.
[0134]
  However, in the lighting system of the present embodiment in the washroom 74, for example, the light quantity of the target lighting fixture 80 is changed by the light quantity change correlated with the light quantity change of outside light. I did an act such as washing my face with 74 or straightening my hair.WhenEven if the wakefulness level is lowered because the lighting fixture 8 is dimmed and controlled to irradiate the field of view of the illumination user M so that the amount of light giving the wakefulness effect is obtained. The lighting user M can be awakened, and the effect of increasing the activity efficiency in the future can be given to the lighting user M.
[0135]
  On the other hand, when you go home and wash your hands in the washroom 74, or gargle, you can control the light so that the light intensity of the lighting fixture 80 is irradiated at a lower illuminance level than in the morning or daytime. When you come home after going home, you don't give glare to your eyes when you walk home in the dark at sunset It can reduce the awakening level of the person who wants to go to the desired state of relaxation before going to sleep.
[0136]
  Also, for those who are required to raise their arousal level during normal work hours such as night shifts and to bring them to an active state, increase their awakening level at night when they go out to work, etc. By adjusting the light intensity of the lighting fixtures by changing the light intensity of the lighting fixture by changing the light intensity of the lighting fixture by changing the light intensity of the lighting equipment in the morning to lower the arousal level on the morning to go home, it is possible to adjust the biological rhythm of the person to use at night it can.
[0137]
  As described above, in the illumination system of the present embodiment, the light amount change according to the purpose is changed.DoThus, the biological rhythm of the lighting user M can be adjusted to match the target biological rhythm.
(Embodiment8)
  As shown in FIG. 39, the lighting system of the present embodiment includes a human sensor unit 62 that senses the presence of the lighting user M, and there is a lighting user M output from the human sensor unit 62. Detection information on whether or not there is a lighting user M based on the detection informationWhenIs provided with a control unit 54 having a function of turning on a target lighting fixture 80 by a lighting device 51 having a dimming function.
[0138]
  Thus, in the present embodiment, when the presence sensor unit 62 such as infrared detection detects that the person M exists in the irradiation area of the lighting fixture 80 installed at the entrance 75, the control unit 54 detects the detection information. Detected that person M existsWhenThe embodiment5Based on the light amount change information obtained from the light amount change information generation unit 56 configured in the same manner as described above, the control unit 54 creates control data and sends it to the lighting device 51. Based on the control data received by the lighting device 51, the lighting fixture 80 is dimmed and controlled to irradiate the field of view of the illumination user M with a desired amount of light. On the other hand, when it is detected that there is no illumination user M, the control unit 54 sends a turn-off signal to the lighting device 51, and the lighting device 54 that has received the turn-off signal turns off the lighting fixture 80.
[0139]
  By the way, the entrance 75 is usually in a position where it is difficult for sunlight to enter in the house.AboutThere is not enough light. Therefore, even when entering the entrance 75 for going out in the morning, the arousal level could not be expected to rise.
[0140]
  However, in the illumination system according to the present embodiment, for example, light amount change information correlated with the light amount change of external light is given from the light amount change information generation unit 56 to the control unit 54.,There is a lighting user M at the entrance 75 for going out in the morningWhenIn the case of irradiating the field of view of the person M who uses the dimming control of the light amount of the target lighting fixture 80 so that the light amount gives a wakefulness effect, the wakefulness level is lowered immediately after waking up. The lighting user M can be awakened, and the lighting user can be given an effect of increasing the activity efficiency after going out.
[0141]
  On the other hand, go home and enter the entranceWhenFor example, the lighting device 80 is dimmed and controlled so that the amount of light is irradiated at a lower illuminance level than in the morning or daytime, so that the eye adapts to a dark state such as walking home in the dark at sunset.DazzlingIt is possible to reduce the awakening level of the lighting user M between going home and going to sleep, such as not giving extra light and not giving the extra awakening effect that is not needed when going home, and bringing it to the desired relaxing state before going to sleep. it can.
