Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses a sensor that senses various fluctuation (1 / f) characteristics in the natural world, and has a light source having a light source that changes according to a change in an external signal sensed by the sensor. Regarding

[0002]

2. Description of the Related Art Illumination devices generally used in the past are those which are turned on by using a light source having a certain luminous intensity.
Alternatively, the user may turn on the light source by using a light source that has been dimmed to a desired light intensity, but the illumination by such a lighting device does not change and is monotonous. Therefore, an illumination device having a light source capable of automatically adjusting the light intensity is known. However, such automatic light adjustment may cause an uncomfortable feeling in the illumination, and a comfortable illumination cannot be obtained.

Therefore, as a means for providing comfortable illumination, there is known one that applies the fluctuation (1 / f) characteristic to illuminate (see Japanese Patent Laid-Open No. 2-44693). Further, as a means for obtaining the feeling of the atmosphere of candle lighting, a method of changing the lighting in accordance with a change in wind speed is known (Japanese Patent Laid-Open No. 3-4).
1440).

[0004]

However, in the former example, the specific configuration is not described, and the configuration of the current circuit having the fluctuation (1 / f) characteristic is not clear.
Further, it is not clear what range the illuminance range of the fluctuation should be set to. Further, even if the fluctuation current and fluctuation voltage have fluctuation (1 / f) characteristics, the light source that is normally turned on does not change its luminous intensity in proportion to the current and voltage. Does not always have a fluctuation (1 / f) characteristic.

In the latter example, the illumination is only changed by the change of the wind speed, and the change of the wind speed is small especially in the indoor space, and even if there is the wind speed, the wind speed is an artificial change by the air conditioner in the room. So, the only change is that we are using an external signal as the signal source,
It does not always have a fluctuation (1 / f) characteristic.

Further, as in the former example, the fluctuation (1 /
f) In the case of storing the data having the characteristic and obtaining the output, the change means that the stored content is read out, and if it is continuously used for a long time, the same change is repeated and becomes a periodic change. is there. According to the present invention, it is possible to eliminate the above-mentioned problems, and it is not necessary to always give a change having a fluctuation (1 / f) characteristic to a light source to obtain monotonous illumination.
Moreover, the purpose is to obtain comfortable lighting.

[0007]

An illumination device according to the present invention is for achieving the above object, and the invention of claim 1 is a change signal source for changing the light quantity in time series.

[0013]

Next, the operation of the lighting device according to the present invention will be described. The signal input by the wind speed sensor that detects the change in wind speed and outputs its strength is shaped by the waveform shaping unit, and the signal from the waveform shaping unit is converted to the dimming signal by the signal conversion unit. The light intensity of the light source is adjusted by the light control device that lights the light source of the light intensity according to the optical signal.

When, for example, an incandescent light bulb is used as the light source, the light intensity is changed so as to give an image of the fluctuation of the flame due to the surrounding wind, as in the case of a real candle, and an artificial light such as the interior of a room is used. Even in a room where air flow changes, comfortable lighting that has a fluctuation (1 / f) characteristic and changes in luminous intensity can be obtained.

Embodiments of the present invention will be specifically described below with reference to the drawings. FIG. 1 (A) is a block diagram of a first embodiment of an illuminating device according to the present invention, in which 1 is a wind speed sensor which detects a change in wind speed and outputs its strength, Reference numeral 2 denotes a waveform shaping unit having a function of shaping the signal input by the wind speed sensor 1, 3 is a signal conversion unit that converts the signal from the waveform shaping unit 2 into a dimming signal, and 4 is a signal conversion unit 3
The dimming device 5 for turning on the light source having the light intensity corresponding to the dimming signal converted by the above is a light source. The type and the number of the light sources 5 can be arbitrarily selected.

Further, FIG. 1B shows an operation diagram inside the waveform shaping section 2, but even if the input waveform from the wind velocity sensor 1 is an arbitrary waveform, it is passed through the fluctuation (1 / f) filter F. As a result, a fluctuation (1 / f) waveform output is obtained at the output side of the waveform shaping section 2. That is, the wind velocity sensor 1 is
The signal output from the waveform shaping section 2 is input to the waveform shaping section 2, and the waveform of the signal input to the waveform shaping section 2 has a fluctuation (1 /
f) The signal is shaped and output.

Considering that the wind speed sensor 1 obtains an analog output according to the strength of the wind, the relationship between the input and the output depending on the wind speed (m / s) is as shown in FIG. The relationship can be arbitrarily changed by setting the sensitivity. FIG. 3 shows a characteristic diagram of the fluctuation (1 / f) filter F in the waveform shaping section 2. The fluctuation (1 / f) filter F has, for example, a frequency characteristic of (-10 dB / oct). To use. In this way, the waveform shaping section 2 can output a signal having a fluctuation (1 / f) characteristic regardless of the strength of the signal from the wind speed sensor 1 according to the strength of the wind. The signal output from the waveform shaping unit 2 is input to the signal conversion unit 3. The signal conversion unit 3 is composed of, for example, a ROM, and the input signal has a dimming amount that has a light intensity corresponding to the signal. It has a function to convert to.

As the light source 5, it is assumed that the input and the output have a relationship as shown in FIG. 4 in order to generate the image of the fluctuation of the flame due to the wind like a real candle. With such a relationship, when the wind becomes strong, the light intensity of the light source 1 becomes small and dark, and conversely when the wind becomes weak, the light intensity of the light source 1 becomes large and bright, and it is as if the candle fluctuates due to the wind. Of.

Here, consider the case where an incandescent lamp is used as the light source 5. Phase control by a triac is generally performed for dimming control, but for that purpose, it is necessary to control the triac at a certain phase angle, and it is necessary for the signal converter 3 to generate a signal therefor. There is. Fig. 5 shows the relationship between the phase angle at which the triac is turned on and the dimming amount.
As shown in FIG. 5A, the conversion table of the signal conversion unit 3 needs to be data as shown in FIG.

As described above, the incandescent light bulb as the light source 5 can be changed in luminous intensity so as to give an image of the fluctuation of the flame due to the surrounding wind, as in a real candle. Even in a room where an artificial airflow change occurs, it is possible to obtain comfortable lighting that has a fluctuation (1 / f) characteristic and changes the luminous intensity. Further, for example, when the input by the wind speed is shown in FIG.
Suppose (B). At this time, an input voltage comparison circuit H as shown in FIG. 6D is provided between the wind speed sensor 1 and the waveform shaping section 2 so that the output becomes zero when the wind speed becomes higher than a certain level. Set. Assuming that the wind speed is set to the level a in FIG. 6A, when the wind speed becomes equal to or higher than the level a, the transistor T is turned on by the output of the rack circuit R in the comparison circuit H to shape the waveform. The input voltage to the part 2 is set to be the same as in the case where the wind speed is the strongest, and
The output of the light source 1 is set to zero as shown in (C). In this way, the incandescent light bulb as the light source 5 has a function of disappearing when the wind blows, like a real candle.

In the above example, an incandescent light bulb is used as the light source 5, but for example, a fluorescent lamp,
The same applies when a high pressure discharge lamp is used. In this case, a dimming circuit according to the type of each light source 5 may be used.
FIG. 7 (A) shows a block diagram of a second embodiment of the illuminating device according to the present invention, in which 1 is a wind speed sensor for detecting a change in wind speed and outputting its strength, Reference numeral 2 denotes an arithmetic unit having a function of making a similar change with respect to a signal input by the wind speed sensor 1, 3 a signal converter for converting a signal from the arithmetic unit 2 into a dimming signal, and 4 a signal converter 3 A light control device for turning on a light source according to the light control signal converted by
Reference numeral 5 is a light source, 6 is a fluctuation signal generation unit that naturally generates a signal having a fluctuation (1 / f) characteristic, 7 is a change detection unit in the calculation unit 2, 8 is a waveform shaping unit in the calculation unit 2, and 9 is a calculation unit. 2 is an input switching unit. Note that, as a specific configuration of the fluctuation signal generator 6, R that can sequentially read data is used.
OM (data for changing 1 / f is written in advance) or a white noise generating circuit and a 1 / f filter, and always output a signal having a fluctuation (1 / f) characteristic. You can Then, the signal from the fluctuation signal generator 6 is input to the calculator 2.

When the signal input by the wind speed sensor 1 is changing, a signal corresponding to the sensor signal is output from the arithmetic unit 2. However, when the sensor signal does not change, the output of the lighting device also changes. It becomes a monotonous device that lights up in a constant state without any problem. Therefore, when the sensor signal does not change, the change detection unit 7 detects it and switches the signal from the fluctuation signal generation unit 6 by the input switching unit 9 in the calculation unit 2 so that constantly changing illumination is performed. [Refer to FIG. 7 (B) input change switching information diagram].

As shown in FIG. 8, for example, let A be the section in which the change in the sensor signal is used and B be the section in which the signal of the fluctuation signal generator 6 is used. Then, the section B having a small change is changed. Further, not only the signal input by the wind speed sensor 1 and the signal of the fluctuation signal generator 6 may be switched, but two signals may be processed and output at the same time. In other words, the fluctuation signal generator 6 is normally operated, and when the signal from the sensor is input, the signal may be processed and output. In this case, FIG. 7 (A)
The function of the input switching unit 9 in the arithmetic unit 2 is not limited to the function of switching only, but the arithmetic function is provided. In this way, even if there is no change in the detection function of the sensor, it is possible to perform illumination that has a fluctuation (1 / f) characteristic that does not have periodicity and always changes, and it is possible to obtain illumination that does not have periodicity and always changes. It can be carried out.

Note that the human sensor 1c can detect the amount of people by using a sensor that can detect the population density at the location by installing a plurality of sensors and calculating the detection amount of each sensor. Further, the sensor 1 can be set to various types such as other temperature sensors and color sensors, and many types can be set. FIG. 9B shows the wind speed sensor 1a,
An example of control operation by each sensor of the illuminance sensor 1b, the human sensor 1c, and the room temperature sensor 1d is shown. For example, if the change in the output of the wind speed sensor 1a becomes small, the output of the human sensor 1c, which is another sensor, is switched to obtain a constantly changing output. Another control example is not to use one sensor output but to combine and output a plurality of sensors that change at that time. This will be described with reference to FIG. 9B.
