Indoor pest repellent device, indoor pest elimination device, and method for repelling pests indoors
This indoor pest repellent device ( 10 ) is provided with: a light source ( 11 ); a light concentrating part (the first light concentrating part ( 13 )) which concentrates a portion of diffused light (LS) emitted from the light source ( 11 ); and a first displacement unit (the rotation mechanism ( 14 )) which changes the relative position of the first light concentrating part ( 13 ) relative to the light source ( 11 ), and which displaces the irradiation region (the light irradiation region (SP 1 )) of the light from the first light concentrating part ( 13 ), said irradiation region being formed on a floor. The light concentrating part is provided with a convex lens.
1. An indoor pest repellent device, comprising:
a light source;
a housing having two or more light concentrating parts, wherein light emitted from the light source is transmitted through each of the two or more light concentrating parts to be emitted to outside of the housing, and each of the two or more light concentrating parts concentrates a portion of the light emitted from the light source; and
a first displacement unit changing a relative position of each of the two or more light concentrating parts relative to the light source and displacing an irradiation region of light from each of the two or more light concentrating parts, which is formed on a floor,
wherein each of the two or more light concentrating parts comprises a convex lens,
the first displacement unit comprises a rotation mechanism, wherein the two or more light concentrating parts are rotationally moved by the rotation mechanism but the light source is not rotated by the rotation mechanism,
the two or more light concentrating parts are arranged apart from each other, and
the housing is configured such that the light from the light source is not emitted from portions other than the two or more light concentrating parts.
2. The indoor pest repellent device according to claim 1 , wherein a plurality of light sources are provided.
3. The indoor pest repellent device according to claim 2 , wherein at least one of the plurality of light sources is arranged at a position shifted from a rotation axis of the rotation mechanism.
4. The indoor pest repellent device according to claim 1 , wherein the light source blinks.
5. An indoor pest repelling method, comprising: attaching the indoor pest repellent device according to claim 1 to a ceiling, and displacing an irradiation region of light formed on a floor by the indoor pest repellent device.
6. An indoor pest repellent device, comprising:
a light source;
a housing having two or more light concentrating parts each concentrating a portion of light emitted from the light source; and
a first displacement unit changing a relative position of each of the two or more light concentrating parts relative to the light source and displacing an irradiation region of light from each of the two or more light concentrating parts, which is formed on a floor,
wherein each of the two or more light concentrating parts comprises a convex lens,
the first displacement unit comprises a rotation mechanism, wherein the two or more light concentrating parts are rotationally moved with the housing by the rotation mechanism but the light source is not rotated by the rotation mechanism,
the two or more light concentrating parts are arranged apart from each other, and
the housing is configured such that the light from the light source is not emitted from portions other than the two or more light concentrating parts.
7. The indoor pest repellent device according to claim 6 , wherein a plurality of light sources are provided.
8. The indoor pest repellent device according to claim 7 , wherein at least one of the plurality of light sources is arranged at a position shifted from a rotation axis of the rotation mechanism.
9. The indoor pest repellent device according to claim 6 , wherein the light source blinks.
10. An indoor pest repelling method, comprising: attaching the indoor pest repellent device according to claim 6 to a ceiling, and displacing an irradiation region of light formed on a floor by the indoor pest repellent device.
