The present invention is a bird and beast repellent device including a plurality of laser light source devices installed at a predetermined distance. Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the bird and beast repellent device 1 includes two laser light source devices 2 installed at a predetermined distance from each other, and each laser light source device 2 has one laser light source 3 composed of a laser oscillator. It is configured in preparation.

Further, the two laser light source devices 2 are configured such that the laser light 7 emitted from each intersects with each other or intersects with each other in a plan view. Even if the laser beams 7 do not intersect each other but intersect each other in a plan view, the separation distance between the two laser beams 7 at the intersection is such that the two laser beams 7 separately irradiate both eyes or one eye of the bird or beast. It is a possible distance. As such a configuration, it is possible to use a configuration in which the two laser light source devices 2 are tilted in each direction so as to intersect each other on an extension line or intersect in a plan view, but the two laser light source devices 2 are respectively. The laser light source 3 provided is tilted in the direction of each other so as to intersect on an extension line or intersect in a plan view, and the respective laser light sources 3 are parallel to each other, but are shown on the laser light source device 2 of either or both. It is possible to adopt a configuration in which a laser light is refracted by installing a light source or a diffractive optical element (DOE).

With such a configuration, it is possible to irradiate one bird / beast 9 to be driven away with laser light from two directions, in other words, to irradiate the bird / beast with laser light from different angles. Since it is possible to irradiate the bird and beast 9 with laser light from two directions, both eyes 91 and 92 of the bird and beast to be driven away can be simultaneously irradiated with the laser light 7 to stimulate them, or one eye of the bird and beast can be simultaneously irradiated. Stimulating by irradiating with laser light from two directions, that is, irradiating both eyes or one eye of the bird or beast from different angles at the same time, and further, the bird or beast irradiates one eye of the bird or beast with the laser light from one side. Even if the eyes, head, and body are moved to avoid it, it is possible to irradiate the laser beam from the other to one or the other eye.

Birds often point only one eye in the direction of dazzling light such as the sun, and for birds and beasts, it is thought that the glare of laser light is buried in the brightness of dazzling light such as the sun. When the laser beam is applied to the eye 92 which is not directly exposed to the dazzling light such as the sunlight 50 of 5, or even the eye 91 which is directly exposed to the dazzling light such as sunlight is the sunlight.

This increases the effect of driving away the targeted birds and beasts. In the case of irradiation of laser light from one direction, even if it is diffused over a wide area or made into a sheet-like light, it is not possible to stimulate both eyes of birds and beasts at the same time, or to stimulate one eye of birds and beasts from two directions at the same time. Can not.

As long as the laser beam 7 can be irradiated from the light source, the arrangement thereof is not particularly limited. Two laser light sources so that each laser beam 7 from the two laser light source devices 2 can easily stimulate both eyes 91 and 92 of the bird and beast 9 simultaneously or one eye of the bird and beast from two directions at the same time. When each of the laser beams 7 from the device 2 is one, it is preferable to install two laser light source devices 2 so that the laser beams 7 are located on the same plane. As shown in FIG. 2, when there are a plurality of laser beams 7 from the two laser light source devices 2, the two laser light source devices 2 are arranged so that the bundle 70 of the laser light 7 intersects with each other. It is preferable to install it.

As described above, by stimulating both eyes 91 and 92 of one bird and beast 9 to be driven away by the laser light 7 emitted from each laser light source device 2 at the same time or one eye of the bird and beast at the same time from two directions. Since the effect of repelling is enhanced, the distance W that the two laser light source devices 2 are separated from each other is such that the laser light 7 emitted from the two laser light source devices 2 is directed from one bird and beast 9 to be driven away from two directions. The distance to be irradiated. Within such a range, the distance W between the two laser light source devices 2 is not limited, and can be determined according to the distance to the bird / beast 9 to be driven away.
