DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric lighting apparatus for artificially expressing the flicker of a candle flame.
In particular, the present invention relates to a technique for adjusting a power supply amount when a normal lighting device is used.

[0002]

2. Description of the Related Art In various restaurants and stage lighting arts, it is sometimes desired to artificially produce fluctuations in candle flames. Fluctuation of the flame of the candle is visually a fluctuation of the amount of light with a reddish flicker, which has been widely used in the past since a light amount adjusting substrate using a filament material has been developed.

On the other hand, a lighting device using such a filament material has a short life (for example, about 140 to 300 hours), has a high running cost in a restaurant or the like, and has difficulty in producing a desired lighting effect. was there.

[0004] Therefore, ordinary lighting equipment (light bulb,
There has been a demand for a technique of expressing the fluctuation of a candle flame using a fluorescent light. As a basic technique for responding to such a request, there is, for example, the invention described in Japanese Patent Application Laid-Open No. 03-87524. This is a technique relating to a fireplace, in which a 1 / f fluctuation voltage is applied to an incandescent light bulb while a combustion device such as a gas burner is shielded with frosted glass to give a viewer a visual effect of the fluctuation. This technique is excellent in expressing fluctuation using frosted glass.

In addition, Japanese Unexamined Patent Publication No. 09-106890 discloses a technique for expressing fluctuations by adjusting the amount of power supplied to a lighting device. This generates a dimming signal based on a plurality of types of data stored in a memory.

Japanese Unexamined Patent Application Publication No. 09-326299 proposes using a noise source affected by wind from the outside, and generating fluctuations in the amount of illumination light based on the signal value of the noise source.

[0007]

The illuminating devices proposed in the past are common in that the fluctuation of the flame is created through some dimming means, but each has the following problems.

First, a technique using the 1 / f fluctuation voltage is as follows.
This is to generate a fluctuation signal that becomes 1 / f when the frequency is f, and utilizes the fact that the 1 / f spectrum matches the basic rhythm of the human body and provides comfort. By the way, in the embodiment described in Japanese Patent Application Laid-Open No. 03-87524, a DC voltage is applied to both ends of solid carbon, and a fine 1 / f fluctuation voltage is generated at both ends of solid carbon. It describes that this is used for amplification.

The problem with this method is that when the direct current applied to the solid carbon is constant, the generated fluctuation voltage tends to repeat the same pattern, and the fluctuation of the flame tends to be monotonous. It is conceivable to change the voltage on the power supply side in a predetermined pattern, but the device configuration becomes complicated, and the monotony of the generated rhythm cannot be basically eliminated.

Next, a method of changing the light amount of the illumination device based on a plurality of types of data stored in the memory (Japanese Patent Laid-Open No. H10-258, Japanese Patent Laid-open No.
No. 9-106890), it is difficult to create data for creating a change pattern. When a random number is used, the fluctuation of the flame cannot be approached, so that the present invention measures the amount of change in the flame of the candle and controls the amount of light based on the measured data (claim 3). .

However, in this method, practical problems remain, such as the trouble of actually measuring the amount of change in the flame over a long time, the trouble of storing the measured data in a memory, and the limited number of types of the measured data. . Especially when controlling a large number of lighting fixtures based on a limited number of measured data in a restaurant with a large floor area, the rhythm of fluctuations tends to be monotonous as a whole, and the real candles will naturally flicker naturally. I can't direct it.

On the other hand, in a system using a noise source affected by wind (Japanese Patent Laid-Open No. 09-326299), the change pattern is not limited and the device configuration can be simplified. It is described that the noise source is housed in a perforated housing, for example, and the fluctuation of the flame is controlled by the strength of the wind passing through the housing.

The problem in this case is that it is necessary to find a wind location that generates a natural and pleasant fluctuation rhythm for each facility, and it is necessary to arrange a plurality of noise sources so that the fluctuation does not become monotonous. For example, when the system is introduced, the arrangement number and positioning of the noise sources are complicated. The noise source may be arranged near a wall surface, a ceiling, or behind a ceiling, but it is difficult to change or add a position after the arrangement.

SUMMARY OF THE INVENTION An object of the present invention is to provide a dimming means which can freely generate more change patterns with a simple device configuration.

[0015]

In order to achieve the above object, a light source driving device according to the present invention includes an electric lighting device and a power supply device for supplying power to the lighting device. Light control means for randomly changing a power supply amount to the lighting equipment with time; the light control means includes a light control source including music data and a light amount corresponding to a volume output from the light control source; And a light receiving means for receiving a change in the amount of light of the light emitting means, and a power supply controller for adjusting and controlling the amount of power supply from the power supply to the lighting fixture based on the amount of light received by the light receiving means.

It is desirable that the music data stored in the dimming source include at least one or more music data organized as one music piece.

[0017]

The light source driving device according to the present invention controls the light amount of the lighting device based on the pattern of the sound generated by the music data. Music data is usually composed of musical instrument performance and / or vocal music, and rhythm and strength are almost infinite. In particular, the rhythms and dynamics of famous music often take a change pattern that ordinary humans feel comfortable, and when this is used for fluctuations in lighting,
Very similar to the pattern of fluctuations in a candle flame.

Moreover, the fluctuation pattern differs for each music. Even for the same song, the dynamic pattern of the sound differs depending on the musical instrument, singer, and player used. It should be noted that the skill of the performer has little effect on the effect of fluctuation.

The music data includes, for example, classical music, jazz music, musical, rock, enka, pops, etc. for each genre. When a natural fluctuation of a candle is produced,
In many cases, a song in which a loose melody and a melody with a rapid tempo are mixed in a short time, for example, a movie music or a march is preferable. It should be noted that the upper limit and the lower limit of the power supply value can be freely set by adjusting the filter as needed. Classical music is excellent for producing large flame changing patterns such as torches rather than fluctuations in candle flames, depending on the author and playing habits, such as suddenly changing from long lasting melody to rapid melody. . For example, nursery rhymes, folk songs, and enka songs with a certain sense of melody are good for the production of flames on a summer night without wind.

In the music data according to the present invention, since the intensity pattern of the sound is transferred between the light emitting element and the light receiving element, and the power supply voltage to the lighting apparatus is controlled on the light receiving side, the fluctuation pattern of the fluctuation in each lighting apparatus is provided. Can be easily exchanged by changing the music data that drives it. Data exchange is easy, regardless of location.

Since the music data shows a complicated melody change within a short time of about three minutes, even if the same music is repeated, the viewer does not notice that the same pattern is repeated within a fixed time. You can cut and combine the songs in the middle, but it is not necessary for the production of fluctuation, and there is a concern that the artificially edited change pattern will hinder the comfort of nature, so repeat the same song or at most a few songs Is desirably used as a change pattern of one lighting device.

[0022]

FIG. 1 shows an example of a light source driving device according to the present invention. This light source driving device surrounds an electric lighting device 11 such as a light bulb or a fluorescent lamp with a light-transmitting shielding member 12 such as frosted glass, and a reading unit 22 from a music data memory 21 storing preferable music data. The music data is read out over time through the device, and the light emitting device 23 is driven according to the volume. The light of the light emitting device 23 is
And applies a voltage corresponding to the amount of received light to the lighting device 11. 25 is a voltage controller and 26 is a power supply.

The lighting device 11 may be of any type as long as it is an electrically driven light source, but is most preferably a light bulb in view of equipment costs and lighting effects. Since the shielding member 12 causes the flame of the candle to fluctuate, it is preferable to use white or colored frosted glass, stained glass with decorative design, or the like.

As the music data memory 21, it is easiest to use, for example, an IC memory. However, any device can be used as long as it can extract and reproduce music data as an electric signal, such as a CD player device, a magnetic tape device, and a DV device.
A music signal generated by a D player device or a computer terminal device may be used. Since there is no need to reproduce sound due to changes in air vibration, a device for sound reproduction such as a speaker is not required.

The light-emitting device 23 and the light-receiving device 24 can be constituted in principle by, for example, a light-emitting diode and a photodiode, respectively, and the voltage controller 25 can be constituted by an amplifying transistor circuit. This is performed by a phototransistor or a photocoupler in which a light emitting unit and a light receiving unit are integrated. The structure of the members for transmitting and receiving light can be appropriately designed as long as the device is compact.

Therefore, according to this device configuration, for example, the lighting device 1 is based on music data stored in an IC memory.
It is possible to control the power supply amount to 1 with an infinite change pattern, and even in an environment where many lighting devices fluctuate simultaneously, it is possible to reliably prevent fluctuation tuning.
It is possible to produce the fluctuation of the flame in a natural environment. Further, since the fluctuation pattern can be freely changed according to the season and the difference in atmosphere, a wide use can be created.

[0027]

As described above, according to the light source driving device of the present invention, more change patterns can be freely generated with a simple device configuration.
