Description

The present invention relates to a lighting device and a lighting method. More specifically, it relates to lighting devices and lighting methods that can create an appropriate lighting environment stepwise or steplessly according to changes in the surrounding conditions such as temperature and atmospheric pressure due to changes in the weather and the passage of time. is there.

By installing street lights along the road, the streets are illuminated at night, and the safety and comfort of road traffic are maintained. In addition, many of these street lights have a built-in timer, and since the time for turning on and off is set in advance, the lights are turned on and off automatically when the set time is reached.

However, the time suitable for turning on and off is not always constant, and even in the same place, the sunset time differs depending on the season and the longitude. If the lights are turned on and off uniformly at the same time without considering the current situation, it is safer to turn on the lights even if they are bright enough and do not need lighting, or the surroundings become dark and turn on. Nevertheless, there is an inconvenience that the light is not turned on.

Therefore, as shown in Patent Document 1, an "illumination device" that controls turning on and off of an illuminating body based on the output of a sunshine sensor has been proposed. As a result, when it is determined that the solar cell cannot receive sunlight, the illuminator is turned on and the light of the illuminator is received to generate power, and when it is determined that the solar cell can receive sunlight, the illuminator is turned off. It can be generated by sunlight.

JP-A-2017-111912

However, in the invention described in Patent Document 1, the illuminator is simply turned on and off depending on whether or not the output value of the sunshine sensor exceeds the threshold value. For example, the color temperature of the illumination or the intensity of the light depends on the season. It does not create an appropriate lighting environment stepwise or steplessly according to changes in the surrounding conditions such as temperature and pressure due to changes in the weather and the passage of time, such as gradually changing the temperature. ..

The present invention has been devised in view of the above points, and the appropriate lighting environment is stepwise or steplessly set according to changes in the surrounding conditions such as temperature and atmospheric pressure due to changes in the weather and the passage of time. It is an object of the present invention to provide a lighting device and a lighting method that can be produced.

In order to solve the above problems, the illuminating device of the present invention includes an illuminating body, an illuminating unit having an output regulator that adjusts the output of the illuminating body stepwise or steplessly, and a situation around the illuminating unit. A judgment unit that judges the surrounding situation based on the surrounding information about the surrounding situation of the lighting unit obtained by measuring the above, and a color temperature or dimming of the illuminating body based on the surrounding situation judged by the judgment unit. A control unit having an output determination unit that determines the output of the illuminator, and a transmission unit that transmits output information regarding the output of the illuminator to the output regulator in response to the determination of the output determination unit, the illuminator, and the illuminator. It is provided with a power supply unit that supplies power to the control unit.

Here, the control unit has a determination unit that determines the surrounding situation based on the ambient information about the surrounding condition of the lighting unit, which is obtained by measuring the surrounding condition of the lighting unit. From the surrounding information obtained by measuring the situation (for example, temperature, humidity, pressure, amount of light, or the amount of power generated when generating electricity using solar power generation), the surrounding situation of each lighting device is individually judged. can do.

For example, for two adjacent or adjacent luminaires, one luminaire is judged to be receiving sunlight because it has a sufficient amount of power generation, and the other luminaire has an insufficient amount of power generation (or the temperature is low). ) Therefore, it can be judged that it is in a slightly dark and cold state, such as being located behind a building.

Further, since the control unit has an output determination unit that determines the color temperature of the illuminating body or the output of dimming from the surrounding conditions determined by the determination unit, the surrounding conditions of each lighting device determined by the determination unit. It is possible to determine the color temperature of the illuminating body and the output of dimming so as to obtain an appropriate lighting environment according to the above.

The output is determined, for example, to determine the output such as the color temperature and dimming of the illuminator. Specifically, the appropriate color temperature (usually expressed in the unit of Kelvin) is determined. Alternatively, it means determining the dimming output (usually represented by "0 to 100%").

Further, the transmission unit that transmits output information regarding the output of the illuminator to the output regulator according to the determination of the output determination unit of the control unit, the illuminator, and the output of the illuminator are adjusted stepwise or steplessly. The illumination unit having an output regulator can adjust the output of the illuminating body stepwise or steplessly via the output regulator based on the output information transmitted from the transmission unit. That is, since the output can be controlled stepwise or steplessly with respect to the color temperature or dimming of the illuminator by the control unit, it responds to changes in the surrounding conditions such as temperature and atmospheric pressure due to changes in the weather and the passage of time. Can create an appropriate lighting environment step by step or steplessly

Note that "adjusting the output of the illuminating body stepwise or steplessly" means, for example, that the dimming output of the illuminating body is not only switched between turning on and off the illuminating body, but also dimming the illuminating body. It means adjusting the output so that the output of can be performed in various patterns. Specifically, the illuminator can provide a lighting environment between the lit state and the lit state such as "slightly dark state" and "slightly bright state" in addition to the lit state and the extinguished state in a stepwise or stepless manner. Adjusting the output.

Further, for example, the color temperature does not always output at the same color temperature, but adjusts the output of the illuminator so that various patterns of color temperature can be provided. Specifically, by providing illuminators with multiple color temperatures, it provides warm lighting in cold weather, and provides lighting that makes you feel cool in hot weather, and you can feel the heat and cold strongly. If there is no time, it means adjusting the output of the illuminator so that it can provide illumination with a neutral color between the two.

That is, it is possible to output in any of a plurality of output patterns according to the surrounding conditions, and it is possible to provide a lighting environment that more closely matches the surrounding conditions.

Further, the lighting unit and the control unit can be operated by electric power by the power supply unit that supplies electric power to the lighting unit and the control unit.

Further, the control unit has a surrounding information storage unit that stores surrounding information, and the determination unit determines the surrounding situation from the surrounding information stored in the surrounding information storage unit and the surrounding information stored before that. When doing so, not only the surrounding information acquired now, but also the difference in the surrounding information acquired before that is grasped as the amount of transition, and the change in the surrounding situation with the passage of time is recognized and the surroundings at the present time You can judge the situation.

Specifically, when the difference between the atmospheric pressure and the previous ambient information is grasped as the amount of transition, if the atmospheric pressure is gradually increasing, it is determined that the weather is recovering, and the output determination unit described later determines that the weather is recovering. , The output of the illuminating body corresponding to this (for example, since it is expected that the surroundings will be brightened soon, the dimming output is set to be slightly darker). In this way, an appropriate lighting environment can be created stepwise or steplessly according to changes in the surrounding conditions such as temperature and atmospheric pressure due to changes in the weather and the passage of time.

When the power supply unit has a photovoltaic power generation function, the power generated by the photovoltaic power generation function can be supplied to the lighting unit and the control unit. In addition, electric power can be supplied even when a commercial power source is not available.

In addition, when the ambient information is at least information on the temperature and the amount of power generation or the amount of light, the judgment unit may judge the surrounding situation based on the information on the temperature and the amount of power generation (or the amount of light) around the lighting device. it can. As a result, the temperature around the lighting device can be determined by the determination unit of the control unit from the information on the temperature. Further, the brightness around the lighting device can be determined by the determination unit of the control unit from the information on the amount of power generation (or the amount of light). As a result, the appropriate lighting environment can be stepwise or steplessly set according to changes in the weather, which is determined based on at least the temperature and the amount of power generation (or the amount of light), and changes in the surrounding conditions such as temperature and atmospheric pressure with the passage of time. Can be created as a target. It should be noted that the ambient information is not limited to the temperature and the amount of power generation (or the amount of light), and it is conceivable to judge including, for example, humidity, atmospheric pressure, wind speed, wind direction, amount of ultraviolet rays, and the like.

In addition, the transmitter, the illuminator, and the illuminator that transmit output information regarding the on / off time and color temperature of the illuminator at the current date and time or the output of dimming to the output adjuster according to the determination of the collation determination unit. An illuminator having an output regulator that adjusts the output stepwise or steplessly causes the transmitter to transmit output information to the output regulator, and the output regulator bases the illuminator on and off the time and color based on the output information. The temperature or dimming output can be adjusted stepwise or steplessly. That is, the output of the color temperature or dimming of the illuminator can be controlled stepwisely or steplessly by the control unit, and an appropriate lighting environment can be created according to changes in the surrounding conditions such as temperature and atmospheric pressure with the passage of time. It can be produced stepwise or steplessly.

Further, in the present embodiment, the storage battery 11 has a capacity capable of supplying electric power for 2 to 3 days in a non-charged state, and this capacity can be arbitrarily set.

[About containment unit 5]
The accommodating unit 5 houses a measuring unit 50 having various sensors and a control unit 51 that controls the lighting unit 2 described later by the measurement information sent from the measuring unit 50.

[About measurement unit 50]
The measuring unit 50 includes a temperature sensor 50a for measuring the ambient temperature of the illumination lamp 20, a humidity sensor 50b for measuring humidity, a barometric pressure sensor 50c for measuring atmospheric pressure, and a power generation sensor 50d for measuring the amount of power generated by the solar panel 10. It is provided. The sensor provided in the measuring unit 50 is not limited to the above-mentioned sensor, and any sensor may be used as long as the surrounding condition of the lighting device A can be grasped from the measured value. For example, an illuminance sensor or an ultraviolet sensor can be considered. .. Further, the lighting device A can also use a commercial power source, and in this case, an optical sensor (not shown) is provided in place of the power generation amount sensor 50d.

The measurement data measured by the temperature sensor 50a, the humidity sensor 50b, the barometric pressure sensor 50c, and the power generation amount sensor 50d of the measuring unit 50 is sent to the control unit 51 as measurement information, and the output of the illumination lamp 20 is determined in the control unit 51. Used for. The measurement information is an example of surrounding information.

[About control unit 51]
The control unit 51 periodically receives measurement data regarding the surrounding conditions of the lighting device A obtained by the measuring unit 50 as measurement information, and the surroundings of the lighting device A from the measurement information received by the receiving unit 51a. The output determination unit 51b for determining the situation of the above, the output determination unit 51c for determining the output of the illuminating lamp 20 from the surrounding conditions of the lighting device A determined by the determination unit 51b, and the output adjustment according to the determination of the output determination unit 51c. Measurement information storage that stores the measurement information received by the transmission unit 51d that sends the output information related to the output of the illumination lamp 20 to the device 21 and the reception unit 51a, and also stores the difference between the measurement information acquired so far as a transfer amount. It has a part 51e.

Specifically, the receiving unit 51a receives the measurement information regarding the measurement data around the lighting device A measured by the sensors 50a to 50d of the measuring unit 50 at intervals of 30 minutes. The interval at which the receiving unit 51a receives the measurement information is not limited to this, and if the measurement information for each short time is required, the interval may be 1 second or 0.1 second, which is roughly defined. If it is sufficient to acquire the measurement information at various intervals, it can be arbitrarily determined such as receiving the measurement information at 10-minute intervals, 30-minute intervals, 1-hour intervals, or irregularly. In the present embodiment, the measurement information is transmitted from the measurement unit 50 to the reception unit 51a by wire communication.

Further, the determination unit 51b determines the surrounding situation of the lighting device A from the measurement information received by the reception unit 51a. For example, a case where the measurement data at a certain time point is a temperature of 5 ° C., a humidity of 80%, an atmospheric pressure of 1000 hPa, and a power generation amount of 45% will be described. Here, in the present embodiment, the rated capacity of the solar panel 10 is 50 W, and the set value of the power generation amount is set to 70% of the rated capacity. The set value of the amount of power generation is a threshold value when the lighting lamp 20 is turned on and off.

Further, when the determination unit 51b determines the surrounding situation of the lighting device A, the measurement information storage unit 51e saves the measurement information and calculates the transfer amount from the difference from the measurement information at the time of the previous acquisition. It is sent to the determination unit 51b. The determination unit 51b determines the surrounding condition of the lighting device A in consideration of this amount of variation. Thereby, the surrounding situation of the lighting device A can be determined not only from the surrounding information at a specific date and time but also from the previous surrounding information.

Specifically, when the difference between the atmospheric pressure and the previous ambient information is grasped as the amount of transition, if the atmospheric pressure is gradually increasing, it is determined that the weather is recovering, and the output determination unit 51c described later is determined. In, the color temperature of the illuminator or the dimming output (for example, since it is expected that the surroundings will be brightened soon, the output is set to a slightly darker dimming output) according to this is stepwise or absent. It can be done in stages. In this way, an appropriate lighting environment can be created stepwise or steplessly according to changes in the surrounding conditions such as temperature and atmospheric pressure due to changes in the weather and the passage of time.

The measuring unit 50 constantly measures the information around the lighting device A, and the measurement data is the time when the receiving unit 51a receives the measurement information from the measuring unit 50.

Below, as an example, an example in which the surrounding situation of the measuring device A is determined from the measurement data measured by the measuring unit 50 is shown.

Since the current temperature is 5 ° C and the amount of transition compared to the measurement information at the time of the previous acquisition is within the range of ± 5 ° C, the low temperature condition continues, and it took from November to March. Judge that it is a cold time. Further, the determination unit 51b determines that it is raining because the humidity is 80% and the amount of transition when compared with the measurement information at the time of the previous acquisition is not large.

In addition, it is judged that the atmospheric pressure will gradually recover in the future because the atmospheric pressure is 1000 hPa and the atmospheric pressure has begun to rise due to the amount of transition when compared with the measurement information at the time of the previous acquisition. Further, since the amount of power generation is 45%, which is less than 70% of the set value, it is judged that the state is dim.

From the above, in the judgment unit 51b, it is a cold season from November to March, it is raining, but it is about to stop and the weather is recovering in the future, and the amount of power generation is below the set value. It is determined that the periphery of the lighting device A is dim.

Based on the determination of the determination unit 51b, the output determination unit 51c determines that the output of the illumination lamp 20 is appropriate for the color temperature output of 3000 K, which is a warm color system, and the dimming output of 70% bright. .. Then, the transmission unit 51d sends output information to the output regulator 21 so that the output of the color temperature of the illumination lamp 20 is 3000 K (Kelvin) and the output of dimming is 70%. In this way, the illumination lamp 20 is controlled by the control unit 51.

Further, the output regulator 21 adjusts the output of the illuminating lamp 20 based on the output information to provide a warm and bright illuminating environment from the illuminating lamp 20. As a result, the person around the lighting device A can visually feel the warmth, and even if the surroundings are slightly dim, sufficient brightness can be obtained around the lighting device A.

The output setting of the illumination lamp 20 based on the above measurement data is an example and is not limited to this. For example, when the dimming output is set to 50% instead of 70%, or when the surroundings are dim. Can be set arbitrarily, such as shortening the lighting time.

The output of the illuminating body 20 determined by the output determination unit 51c is transmitted to the transmission unit 51d, is transmitted from the transmission unit 51d to the output regulator 21 as output information, and is transmitted to the cloud 7 via the communication unit 3. It will be saved. At this time, the measurement data stored in the measurement information storage unit 51e is also transmitted to the cloud 7.

Further, in the present embodiment, the lighting device A is described with the measuring unit 50 and the control unit 51 as separate bodies, but the present invention is not limited to this, and both are integrated such as including the measuring unit in the control unit. A lighting device is also conceivable.

As described above, the lighting device A can determine the surrounding situation from the measured data and provide an appropriate lighting environment stepwise or steplessly according to the surrounding situation.

[About lighting unit 2]
As shown in FIG. 3A, two types of LEDs 20a and 20b having different color temperatures are alternately arranged in row units in the illumination lamp 20 of the illumination unit 2. The LED 20a has a warm color temperature (3000K), and the LED 20b has a cold color temperature (5000K). It should be noted that the arrangement of LEDs is not limited to the arrangement of LEDs alternately in a row unit, and for example, as shown in FIGS. 3 (b) and 3 (c), the LEDs are individually arranged alternately. Is also possible. Further, the LED is not limited to the above two types of color temperatures, and can be set arbitrarily.

As for the LEDs 20a and 20b, the LED having one of the color temperatures is turned on by the control from the control unit 51, and the LED having the other color temperature is turned off during this period. By lighting only one of the LEDs in this way, the period until the cumulative lighting time of each LED reaches a predetermined time can be extended, so that the replacement period of the illumination lamp 20 can be set longer, which is economical. Is.

Further, the LEDs 20a and 20b of the illumination lamp 20 are turned on by the electricity generated by the solar panel 10 or the electricity supplied from the storage battery 11, and the dimming output can be set according to the output information from the control unit 51. it can.

Specifically, as described above, the output regulator 21 that has received the output information from the control unit 51 determines the color temperature and dimming output (light intensity) according to the surrounding conditions of the lighting device A. Can illuminate the surroundings. The lighting fixtures used for lighting lamps are not limited to LEDs.

[About communication unit 3]
The communication unit 3 includes a communication antenna 30, and the measurement data measured by each sensor of the measurement unit 50 by the communication antenna 30 is stored on the cloud 7 of the Internet. The data saved in the cloud 7 can be read from an external mobile terminal (not shown), and the mobile terminal can directly transmit output information or information to be displayed on the display panel 4 to each lighting device. .. Here, it is assumed that the mobile terminal stores application software that determines and transmits the output information of the lighting 20 from the measurement information. It should be noted that a person can determine the color temperature and dimming output of the lighting device A from the measurement information on the cloud 7 and transmit the output information to the output regulator 21.

Therefore, the judgment unit 51b sets the lighting for spring and summer (cold color temperature 5000K) and lights. It is determined that the surroundings of the device A have a certain brightness, and the dimming output is set to 30%. As a result, it is possible to provide a lighting environment for spring and summer around the lighting device A.

(ST6; Judgment process to judge the surrounding situation based on the setting condition 2)
In the present embodiment, the temperature is measured to be 5 ° C., the humidity is 80%, 1000 hPa, and the amount of power generation is 45% of the rated capacity, so the process proceeds to ST6. In ST6, it is determined whether or not the setting condition 2 (temperature less than 15 ° C., humidity 40% or more, atmospheric pressure 995 hPa or more, power generation amount less than 50%) is satisfied. In the present embodiment, it is determined from the above measurement data that the setting condition 2 is satisfied, and the process proceeds to ST7. If neither of the setting conditions 1 and 2 is satisfied, the process proceeds to ST8. The setting condition 2 is not limited to the above conditions, and can be arbitrarily set, and three or more setting conditions can be set.
