DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a firefly protection lamp having a fire-fighting function suitable for guiding and collecting fireflies which are said to inhabit a clear stream or the like.

[0002]

Conventionally, in order to provide a firefly protection light which does not adversely affect the fireflies' habitat, for example, Japanese Unexamined Patent Application Publication No. 11-25722 discloses a security light provided in an urban area or in a park. As an illumination lamp such as a general illumination lamp to be installed, a sodium lamp that emits orange color is provided above a pillar whose lower end is buried in the ground, and the upper and outer peripheral portions of the sodium lamp are surrounded by a lighting cover, and In addition to providing an opening capable of illuminating in the direction, and providing an illuminance adjustment mechanism made of an acrylic plate capable of adjusting the illuminance and adjusting the light color below the sodium lamp in the illumination cover, is disclosed. ing.

[0003] However, the purpose of such a firefly protection light is to prevent the emission of fireflies in the first place, and it is not that the fireflies are guided to the firefly protection light and actively collected. In addition, unless the illuminance adjustment mechanism is manually operated, the sodium lamp is continuously lit and the illuminance therefrom does not change. Therefore, there is a concern that fireflies that periodically emit light are less likely to be guided to the firefly protection light.

[0004] In addition, another Japanese Utility Model Application Laid-Open No. 63-1606.
No. 08 discloses a firefly model having a light emitting device which is blinked by a blinking device, which is arranged at an appropriate place of a garden light so as to create an atmosphere of a garden where a firefly is present.

[0005] However, this assumes a case where fireflies do not inhabit the garden, and even if there are fireflies in the garden, simply blinking a firefly model having a light-emitting device will cause fireflies in the surroundings. Does not come together.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a firefly protection lamp having a fire-fighting function capable of effectively guiding and collecting fireflies living in a clear stream or the like. .

[0007]

Means for Solving the Problems Claim 1 of the present invention
In order to achieve the above object, the firefly protection lamp having a fire-fighting function of the first illuminant that emits orange-based color,
Blinking means for blinking the brightness of the first illumination source in an approximate trapezoidal wave shape in accordance with the emission cycle of the fireflies.

[0008] According to the above configuration, the first illumination source illuminates in an orange system color suitable for gathering fireflies. At this time, the first illumination source does not merely continuously light or blink, but the flickering means changes its flickering in an approximate trapezoidal wave shape in accordance with the light emitting cycle of the fireflies. The flickering light generated in the orange system color is effectively gathered near the firefly protection light.

[0009] Further, since the orange light is directly radiated from the first illumination source, a filter member for obtaining a desired color is not required.

Further, the firefly protection lamp having a fire-fighting function according to a second aspect of the present invention includes a second illumination source which is continuously lit, a switching operation means, and the first illumination source which is operated by the switching operation means. Alternatively, there is provided an illumination switching unit for turning on one of the second illumination sources.

In this case, if the switching operation means is operated to continuously light the second illumination source, it can be used as an approach light or the like in a season other than the season when fireflies scatter. The utility value as a firefly protection light can be further enhanced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a firefly protection lamp having a fire-fighting function according to the present invention will be described below with reference to the accompanying drawings.

First, the external structure of a firefly protection lamp will be described with reference to FIGS. In FIG. 1, reference numeral 1 denotes a single or a plurality of protective lamp bodies provided at predetermined intervals along a clear stream where fireflies inhabit and along a sidewalk near the clear stream. The protective lamp body 1 has a lower part buried in the ground GL, a pole 3 which is a cylindrical pillar having a lighting part 2 described later built in the upper part, and is detachably provided on the upper part of the pole 3. A dome-shaped cover 4 having an open lower side surrounding the upper and outer peripheral portions.

The illuminating unit 2 includes a globe 5 having a translucent outer shell, a compact fluorescent lamp 6 installed substantially at the center of the globe 5, and a pair of light bulbs 7 provided on both sides of the fluorescent lamp 6. 8 is provided. A blinking unit 9 is provided below the globe 5 as blinking means for changing the brightness (illuminance) of the light bulbs 7 and 8 as illumination sources into an approximate trapezoidal waveform in accordance with the emission cycle of fireflies. Preheating the filament of the fluorescent lamp 6,
A glow starter 10 for applying a voltage to both electrodes of the fluorescent lamp 6 after a predetermined time and a ballast 11 for keeping a constant current after the fluorescent lamp 6 starts discharging are provided. Reference numeral 12 denotes a rod provided to prevent the protection lamp main body 1 from coming off. The power consumption of the fluorescent lamp 6 used in this embodiment is 13 W,
8 consumes 5 W each.

Next, the electrical configuration will be described with reference to the block diagram in FIG. 3 and the waveform diagram showing the time change of the illuminance of the electric bulbs 7 and 8 in FIG. In FIG. 3, reference numeral 13 denotes a control circuit mounted on a printed circuit board (not shown) in the pole 3, which controls all operations of the protection lamp main body 1. The control circuit 13 provided inside the blinking unit 9 controls the brightness of the pair of bulbs 7 and 8 as the illumination source.
There is provided a blinking circuit 14 for changing the light emission cycle of the fireflies into an approximate trapezoidal waveform. Reference numeral 15 denotes a blinking cycle setting means for arbitrarily setting a blinking interval (corresponding to the cycle T in FIG. 4) of the light bulbs 7 and 8, and as a variable operation means capable of externally changing the blinking cycle T. Is connected to the control circuit 13. The blinking period T of the light bulbs 7, 8 is
Genji fireflies and Heike fireflies that live in Japan (Genji fireflies are 2 to 4 seconds, Heike fireflies are about 1 second) are compatible with fireflies other than fireflies. In consideration of this, it is preferable to set the time in the range of 0.5 to 5 seconds. By operating the variable resistor 16, the light bulb 7 can be turned on and off at an optimal blinking period T in accordance with the type and characteristics of the fireflies that live near the place where the protection lamp body 1 is installed.
8 can blink. In addition, the control circuit 13 is operated by a changeover switch 17 which is a changeover operation means.
An illumination switching circuit 18 is provided as illumination switching means for turning on either the fluorescent lamp 6 or the bulbs 7, 8.

The blinking circuit 14 sets the minimum light quantity Pmin to half or less of the maximum light quantity Pmax regardless of the blinking cycle T when the light bulbs 7 and 8 blink. This is to make it as close as possible to the actual flickering of the fireflies, which makes it easier for the fireflies to be guided around the protection lamp body 1. Further, in order to approximate the actual blinking of the fireflies, the blinking circuit 14 includes a CR integration circuit (not shown) having a resistor and a capacitor therein, and supplies power to the electric bulbs 7 and 8 with a sine waveform. Is converted into a CR integrated waveform, so that the flickering of the light bulbs 7 and 8 is changed to a gentle approximate trapezoidal waveform having no corners as shown in FIG.

In this embodiment, two light bulbs 7 and 8 are used, and one or both of them are colored light bulbs, so as to emit orange light. In this case, both bulbs 7 and 8 may be colored bulbs of the same color. However, 500 nm which is not preferable for collecting fireflies
The following frequency components are configured to be cut off. In this way, if the light bulbs 7, 8 themselves develop an orange-based color, not only can the fireflies be effectively guided to the protection lamp main body 1, but also a filter member for obtaining a desired color becomes unnecessary.
The illumination unit 2 and thus the protection lamp body 1 can be downsized.

Next, the operation of the above configuration will be described. Before installing the protection lamp body 1, the blinking period T of the electric bulbs 7 and 8 shown in FIG. 4 is adjusted by the variable resistor 16 in advance according to the type and characteristics of the fireflies growing in the installation place. For example, Genji firefly mainly inhabiting eastern Japan is said to have a light emission cycle of 2 to 4 seconds, and Heike firefly mainly inhabiting in western Japan is said to have a light emission cycle of approximately 1 second. Therefore, at the time of product shipment or installation, the variable resistor 16 is previously adjusted by operating the variable resistor 16 so that the blinking cycle of the light bulbs 7 and 8 substantially matches the light emission cycle of such fireflies.

In order to guide the fireflies to the protection light body 1 thus installed, the cover 4 is mounted on the pole 3 and the changeover switch 17 is operated to switch to the blinking operation mode by the light bulbs 7 and 8. Then, while the fluorescent lamp 6 is turned off, the blinking circuit 14 for blinking the light bulbs 7 and 8 is activated, and the light bulbs 7 and 8 are turned on and off at a predetermined blinking cycle set by the blinking cycle setting circuit 15 as shown in FIG. At T, the blinking operation in which the brightness changes in an approximate trapezoidal wave shape is repeated. In addition, orange light is radiated from the light bulbs 7 and 8 through the globe 5 and is irradiated on the ground GL around the lower part of the pole 3 within a relatively narrow range from the lower opening of the cover 4. You. In this way, the fireflies that live around the protection light main body 1 are guided by the flickering light that changes into an approximate trapezoidal wave color that has developed in the orange system color, and effectively gathers near the firefly protection light.

On the other hand, when the protection lamp body 1 is used as an approach light, the cover 4 is removed from the upper part of the pole 3 and the changeover switch 17 is operated to switch to the continuous lighting mode by the fluorescent lamp 6. Then, while the light bulbs 7 and 8 are turned off, the fluorescent lamp 6 is continuously turned on, and light having a constant illuminance is radiated from the fluorescent lamp 6 to the outside through the globe 5. At this time, since the cover 4 is not provided on the protection lamp main body 1, the illumination unit 2 is not provided.
The light from the fluorescent lamp 6 is radiated in a relatively wide range in the downward and peripheral directions.

Table 1 below shows the experimental results of the effects of fireflies induced by different illumination sources. This experiment is about 10m from a dense area of fireflies (type of fireflies)
A lamp was installed at a distant point, and the number of fireflies flying and emitting in a circle having a radius of about 1 m around the lamp was examined. The lighting fixtures shown in Table 1 were attached to the lamps. The observation time is 10 minutes per pattern.
The blinking cycle of blinking light in each of the patterns (1) to (5) was 2.5 seconds (indicated by, does not blink by continuous lighting). The experiment was performed between 20:00 and 21:30 in an environment of fine weather, a temperature of 15 ° C, and a humidity of 90%. Both the temperature and the humidity are suitable for the firefly growing environment. Also, the surrounding situation was fairly bright with a half-moon, and there were few stagnant fireflies and most were flying around.

[0022]

[Table 1]

According to Table 1 above, it was confirmed that the number of fireflies emitted by the firefly was greater when the illumination source was flickered than when it was continuously lit. As the flickering light color, yellow + yellow was the most able to induce fireflies. Conversely, green + green has a small amount of light and a light color of blue, so it was judged that the color was not very desirable for fireflies. In this experiment, because the surroundings were bright due to the effect of the moon, the number of flying luminescence was small and it could not be said that the conditions were good. Nevertheless, each of the patterns (1) to (4) could induce some fireflies.

As described above, according to the present embodiment, the light bulbs 7 and 8 as the first illumination sources that emit orange-colored colors are provided.
And a blinking unit 9 as blinking means for blinking the light bulbs 7 and 8 in an approximate trapezoidal wave shape in accordance with the emission cycle of the fireflies.

In this case, the light bulbs 7 and 8 illuminate in an orange color suitable for gathering fireflies. At this time, the light bulbs 7 and 8 do not simply light continuously or blink, but instead blink. The flickering circuit 14 makes the brightness change in an approximate trapezoidal waveform in accordance with the light emission cycle of the fireflies, so that fireflies that live in the vicinity are guided by this orange-colored flickering light and firefly protection lights Effectively gather in the vicinity of. In addition, since orange light is directly radiated from the light bulbs 7 and 8, a filter member for obtaining a desired color is not required.

Further, in the present embodiment, there are provided the bulbs 7 and 8 as the first illumination source and the fluorescent lamp 6 which is continuously illuminated as the second illumination source. An illumination switching circuit 18 as illumination switching means for lighting one of the fluorescent lamp 6 and the bulbs 7 and 8 by operation.
Is provided. As described above, by operating the changeover switch 17 to continuously light the fluorescent lamp 6, the fluorescent lamp 6 can be used as an approach light or the like in a season other than the season when fireflies are scattered. Can be further enhanced.

In addition, in the present embodiment, in this embodiment, the blink cycle setting circuit 15 as a blink cycle setting means for setting the blink cycle T of the light bulbs 7 and 8, and the set blink cycle T Variable resistor 16 as variable operating means
Is provided. In this case, when the variable resistor 16 is operated, the blinking period T of the light bulbs 7 and 8 set by the blinking period setting circuit 15 can be varied, so that the type and characteristics of the fireflies that live near the installation of the protection lamp body 1 can be adjusted. The light bulbs 7 and 8 can be flickered at the optimal flicker cycle T.

In this embodiment, since the cover 4 for projecting the light from the lighting unit 2 onto the ground GL is detachably provided so as to cover the periphery of the lighting unit 2, when guiding fireflies, , The light bulbs 7, 8 are blinked by the changeover switch 17,
In addition, if the cover 4 is attached to irradiate the flickering light to the ground, the fireflies repeatedly emit light in synchronization with the flicker on the ground GL within the range of the flickering light. When using as the above approach light, changeover switch
If the fluorescent lamp 6 is continuously turned on by operating the lamp 17 and the cover 4 is removed from the illumination unit 2, continuous light having a constant illuminance can be emitted in the peripheral direction of the illumination unit 2.

The present invention is not limited to the above embodiment, and various modifications can be made. For example, the illumination source is not limited to the combination of the two bulbs 7 and 8 in the embodiment, and various types can be used.
