A support rod mounting portion 12 is fixed to an outer end of the horizontal support shaft 10, and a plurality of pipe-shaped support rods 13 having different lengths are fixed to the support rod mount portion 12 around the horizontal support shaft 10. It is detachably attached by being shifted by each angle. Thus, the bevel gears 9, 11
The support rod mounting portion 12 pivotally supported by the horizontal support shaft 10 is rotated in a vertical plane within a predetermined angle range, and this constitutes a vertical swing mechanism according to the present embodiment.

For example, one support rod 13a has a disk 12a at its base end. , 12b are accommodated so as to be fitted into the grooves 12h, and are sandwiched and supported by the two disks 12a, 12b. Thereby, each support rod 13 can be expanded in a radial or fan shape by appropriately adjusting the angle of each support rod mounting portion 12a to 12f through the horizontal support shaft 10. In this way, by passing a desired number of the support rod mounting portions 12 through the horizontal support shaft 10, the number of the support rods 13 and the light emitting portions 14 can be made a desired number.

In FIG. 8, reference numeral 17 denotes a stand on which the housing 1 is placed and fixed, and reference numeral 18 denotes a plurality of, for example, four piles fixed to the bottom of the stand 17.

The operation of the firefly light emission reproducing device according to the present invention is as follows. First, the pile 18 is inserted into a predetermined ground, and the gantry 17 is fixed. Next, when the drive motor 2 is turned on by the power supply control unit 16, the small disk 3 rotates, and each gear unit 6 is swung within a predetermined angle range in a horizontal plane. At the same time, the support rod mounting portion 12 is also rotated through the bevel gears 9 and 11 in a vertical plane within a predetermined angle range. Further, the light emitting unit 14 attached to the tip of the support rod 13 together with these movements
Blinks under the control of the power supply control unit 16. In this way, it is realized that the plurality of light emitting units 14 move while blinking as if drawing a random and nonlinear trajectory. Looking at these under dark conditions, it is as if the fireflies flickering and flickering.

Further, in the present invention, the following items are realized in order to photograph the light emitting state of the fireflies with a video camera, analyze the details in detail, and specifically approach the natural light emitting state of the fireflies. 1. 1. The light emitting part flickers like a firefly. 2. The light-emitting part moves vertically and horizontally in the space. 3. The light-emitting unit moves irregularly. The moving speed of the light emitting unit is not constant

A specific example is as follows. First, in order to reproduce the flying state of the fireflies,
Was set to 8.3 rotations / minute. Further, in order to realize a state in which a plurality of fireflies emit light randomly at different heights, the length of the support rod 13 supporting the light emitting unit 14 is set to be 200 mm to 1000 mm and different from each other. Six were fixed every time.

Further, the gear unit 6 includes a bevel gear 9.
The bevel gear 11 and the bevel gear 11 have a gear ratio of 1: 2 and two movable angles of 45 degrees, and the bevel gear 9 and the bevel gear 11 have a gear ratio of 1: 1 and a movable angle of 90 degrees. Support rod 1
For No. 3, a 4 mm stainless steel hollow pipe was used in consideration of strength and bending during operation, and black coating was applied to the pipe to prevent reflection.

The light emitting section 14 uses an InGaAlP-based pure green light emitting diode. The light emitting section 14 is covered with a milky white cover 19 in order to reproduce the diffused light of fireflies. The tip is blackened.
Furthermore, a power control unit 1 for controlling light emission
6 has a pulse width of about 3 sec. And the voltage was 5 V. The blinking pattern of the light emitting section 14 was a combination of one light and one light and one light and three light as described above.

[0019]

As described above, according to the present invention, the light emitting portions are sequentially arranged within the movable range of the device of the present invention.
Since repetition of lighting, extinguishing, lighting, etc. is performed while being supported by support rods having different lengths and inclinations, it is possible to realize unpredictable irregular blinking and movement of firefly emission. In addition, since the lengths and inclinations of the plurality of support rods are different, the plurality of light emitting units can evenly fill the space, and at the same time, can change its movable range and speed, whereby a large number of fireflies are flying. The state can be reproduced. In the gear unit,
By using two types of bevel gears with different gear ratios, the movable range and moving speed of the light emitting unit can be made different, and a firefly light emission reproduction state can be realized in a more natural manner. Furthermore, by coloring the support bar black and making it thin,
In a dark place, only the light emitting portion can be made to appear to float in the space.
