As one of the measures to revitalize towns and villages, a firefighting conservation movement is being implemented in various places with the cooperation of local governments. Genji fireflies and heike fireflies in particular are said to live only in clear streams, so the protection movement has the aspect of not only improving the image of towns and villages but also contributing greatly to environmental conservation. However, this approach involves various problems in environmental protection and securing a living base. As one of them, there have been reports of artificial lighting (mainly security lights) affecting firefly habitats. Firefly emission is essential for communication between fireflies,
The strong external light that obstructs and confuses the light emission directly affects the survival of fireflies. Artificial lighting, on the other hand, provides a safe and comfortable living environment for humans. There have been cases where fireflies disappeared after security lights were installed in firefly habitats. Therefore, we experimentally investigated the relationship between the intensity and color of the illumination light and the flying luminescence of the fireflies, and obtained one data in considering the symbiosis of artificial illumination light and fireflies as living light. Then, based on the results of this survey, model lights were manufactured.

板又は半透明クラフトシートを重ねて作り出した。An experimental booth was installed at one corner of the firefly habitat to experimentally investigate the effects of the luminance of the irradiation light source (or the illuminance on the horizontal surface of the illuminated surface) and the light color on the firefly flight luminescence. Then, at least 50 or more heike fireflies were released into the booth under conditions close to the natural environment, and the flying light emission status of the fireflies in the booth when the luminance (or illuminance) and color of the irradiation light were changed was investigated. The experimental booth has a cubic shape, and the upper part of the booth is covered with a plate for installing a light source. At the center of the upper part is a 17 cm × 30 cm square diffusing glass entrance window. The lower part is in contact with natural vegetation and the surrounding area is covered with a fine black mesh sheet so that the fireflies can be observed from outside. The luminance value (or the illuminance value of the illuminated surface) of the irradiation light source into the booth is variably set using two dimmers of three-wavelength fluorescent lamps (for daylight) in the light source booth. The light color of the irradiation light was produced by overlapping a translucent colored acrylic plate or a translucent kraft sheet on the entrance window.

FIG. 3 summarizes the relationship between the horizontal plane illuminance on the bottom of the booth immediately below the light source and the number of fireflies, and the number of fireflies decreases exponentially as the illuminated surface increases. The degree of the reduction is roughly classified into two groups, the light colors being orange (red, orange) and other (white, green, blue). When the illuminance of the illuminated surface was about 1 lux, the orange system decreased by about 25% from the non-lighting state, whereas the other color systems sharply decreased by 70% or more.

る。Fireflies also inhabit urban areas with relatively few houses. Security lights in this area are mainly equipped with security lights for the purpose of public safety at night. Security lights mainly use fluorescent lamps and mercury lamps as light sources. According to JIS road lighting standards, from the driver's point of view, when the traffic volume is low and the lighting environment around the road is dark,
The recommended value of the average road surface luminance of the road is 0.5 [cd / m 2 ]. From the pedestrian's point of view, the condition of the road surface is easily recognized, and the aim is to ensure the safety of walking and to help prevent crime.
It is recommended that the horizontal illuminance on the road be 0.3 to 3 [lx].

面から考えると次のようになる。The empirical fact that the fire emission of fireflies is reduced even on a full moon night (illuminance of about 0.2 lux), and the results of a survey conducted on the relationship between luminance (or horizontal illuminance), light color and the number of fireflies flying, According to road lighting standards, street lights including security lights in firefly habitats are considered as follows in terms of light color and brightness.
