Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the conventional pest repellent device described in Patent Document 1 is a simple device that emits high-intensity flashes by the light emitting device in a blinking manner, so there is a problem that the effect is reduced because the pests become intimidated.

[0006] Therefore, an object of the present invention is to provide a pest repellent device that can effectively suppress animal damage by suppressing the intimidation of pests.

Means for Solving the Problems

[0007] To achieve the above objective, the pest repellent device of the present invention comprises a display unit made of an LED vision, a control unit for controlling the image displayed on the display unit, and a power supply unit, wherein the control unit displays an image that pests will avoid on the display unit. [Effects of the Invention]

[0008] As described above, the pest repellent device of the present invention comprises a display unit made of an LED vision, a control unit that controls the image displayed on the display unit, and a power supply unit, wherein the control unit displays an image that pests will avoid on the display unit. With this configuration, the pest repellent device can effectively suppress animal damage by preventing pests from becoming accustomed to the intimidation. [Brief explanation of the drawing]

[Figure 3] This is a detailed diagram of the display unit. (a) is a type with a built-in circular UV-LED, and (b) is a type with a separate UV-LED. [Figure 4] This is a front view of the modified display unit. [Figure 5] These are explanatory diagrams of different types of unit LED sets. (a) shows the case where UV light also emits light B, and (b) shows the case where UV light alone emits light. [Modes for carrying out the invention]

[0010] Embodiments of the present invention will be described below with reference to the drawings. However, the components described in the following embodiments are illustrative and are not intended to limit the technical scope of the present invention to them alone. [Examples]

[0011] (composition) First, the overall configuration of the pest repellent device 1 of the present invention will be explained using the explanatory diagram in Figure 1. As shown in Figure 1, the pest repellent device 1 of the present invention comprises a display unit 2 made of an LED vision, a control unit 3 that controls the image displayed on the display unit 2, and a power supply unit 4 for supplying power to the display unit 2 and the control unit 3. In this embodiment, the control unit 3 displays an image that pests will avoid on the display unit 2. The form of the LED vision may be flat, curved, or spherical.

[0012] Furthermore, the pest repellent device 1 of this embodiment is further equipped with a sensor unit 5 for detecting pests as an input system to the control unit 3. The sensor unit 5 is preferably an optical sensor such as an infrared sensor or a CMOS sensor that reacts to the heat and movement of pests, and by passing near the sensor unit 5, it senses temperature changes and the movement of pests and sends an ON / OFF signal to the control unit 3.

[0013] As shown in Figure 2, the display unit 2 is composed of a frame 20 that forms the overall outer shape and six LED visions 21. Each LED vision 21 has multiple UV-LED-embedded unit LED sets 22 and 23 arranged at equal intervals vertically and horizontally, as shown in Figure 3(a). In addition, as unit LED sets, as shown in Figure 5, those that emit two wavelengths of light, B (blue) and UV (ultraviolet light), by utilizing UV-LEDs and fluorescent materials (see Figure 5(a)), or those composed only of UV-LEDs (see Figure 5(b)) can be used.

[0014] More specifically, the UV-LED-integrated unit LED sets 22 and 23 consist of a set of three LEDs that emit, for example, R (red), G (green), and B (blue), and a single LED that emits UV (ultraviolet light). In terms of external shape, a circular unit LED set 22 or a square unit LED unit 23 is preferred. The primary colors of the LED unit may be RBY (red, blue, yellow).

[0015] In another embodiment, the LED vision 21 shown in Figure 3(b) has a plurality of three primary color LED sets 24, ... arranged at equal intervals vertically and horizontally, and a plurality of UV-LEDs 25, ... arranged between these three primary color LED sets 24, ... That is, unlike Figure 3(a), in the case of an independent UV-LED type, a unit LED set (24, 25) consists of a three primary color LED set 24 and a UV-LED 25. A three primary color LED set 24 is, for example, a set of three LEDs that emit R (red), G (green), and B (blue). A UV-LED 25 is a single LED that emits UV (ultraviolet light). In addition, for B (blue), secondary emission using a fluorescent material may be used.

[0016] The control unit 3 is a controller that controls the image displayed on the display unit 2, and can use a general-purpose microcomputer (MC) or personal computer (PC). The control unit 3 is connected to the sensor unit 5 as an input system, and to the display unit 2, the sound unit 6, and the laser light emission unit 7 as output systems. The detailed functions of the control unit 3 will be described later. Therefore, when a pest detection signal is input to the control unit 3 from the sensor unit 5, an image that pests will avoid is displayed on the display unit 2, a roar or threatening sound is emitted from the sound unit 6, and laser light is emitted from the laser light emission unit 7. Note that the pest repellent device 1 does not necessarily require the laser light emission unit 7.

[0017] (Functions of the control unit) The control unit 3 is configured to display a moving image on the display unit 2 as an image that repels harmful animals. Furthermore, it is preferable that the control unit 3 is configured to display an image converted into a color space based on the color vision of the target harmful animal on the display unit 2. As this repelling image, not only a moving image (or a still image) of a natural enemy but also a moving image (or a still image) of an inorganic geometric pattern with a color scheme that gives a sense of threat may be used. That is, an efficient effect is obtained by changing the number of primary colors according to the color vision of the target harmful animal. For example, harmful animals with a 4-color type color vision (3-color type color vision + UV) (crows) or 2-color type color vision + UV (deer). By having color visions from type 1 to type 4, variations in the image can be provided. That is, showing an image with a color vision of R or G to a harmful animal that has only color vision of B is ineffective, so the device consumes wasted power and is inefficient. Power saving is possible by matching the visual sensitivity of the harmful animal.

[0018] Furthermore, as a countermeasure against generalization (habituation due to the learning effect of harmful animals), it is preferable that the video content can be replaced. In addition, it is also possible to sustain the repelling effect by changing the color vision of a moving image of the three primary colors that a normal person is watching. Additionally, it is also preferable to add to the moving image by using, for example, an image that evokes natural disasters (fire, lightning strike) through production or an image generated by AI based on an image of a natural enemy. Furthermore, in order to continue the repelling effect, it is also possible to improve the visibility by deliberately changing the resolution of the image by changing the number of pixels in which the LED vision operates.

[0019] Also, the luminance and the lighting / extinguishing timing of a single LED or UV-LED 25 that emits UV (ultraviolet light) and is arranged in the plurality of unit LED sets 22, 23 can be operated in联动 with the luminance and the lighting / extinguishing timing of any color of the plurality of unit LED units of the three primary colors.

[0020] Alternatively, the brightness and lighting / extinguishing timing of a single LED or UV-LED 25 that emits UV (ultraviolet light) and is arranged in a plurality of unit LED sets 22, 23 may operate independently of the brightness and lighting / extinguishing timing of the plurality of three-color LEDs.

[0021] And, as shown in FIG. 1, the pest repellent device 1 of the present embodiment further includes an amplifier unit 61 and a speaker unit 62 as the acoustic unit 6. From the acoustic unit 6, a growl or a threatening sound is emitted in conjunction with the moving image at the timing of detecting a pest.

[0022] And, as shown in FIG. 1, the pest repellent device 1 of the present embodiment further includes a laser light emitting unit 7. The laser light emitting unit 7 may emit laser light in conjunction with the moving image at the timing of detecting a pest.

[0023] (Effect) Next, the effects exhibited by the pest repellent device 1 of the present embodiment will be listed and explained.

[0024] (1) As described above, the pest repellent device 1 includes a display unit 2 composed of a plurality of LED visions 21, a control unit 3 that controls the image projected on the display unit 2, and a power supply unit 4. This control unit 3 projects an image that pests avoid onto the display unit 2. Therefore, the pest repellent device 1 can effectively suppress pest damage by preventing pests from being intimidated.

[0025] (2) Further, since the display unit 2 is composed of a plurality of LEDs (R, G, B) of the three primary colors of light and a plurality of UV-LEDs (22, 23, 25) in the ultraviolet light region, pests can be effectively repelled by using light in the ultraviolet light region. In addition, as a unit LED set, as shown in FIG. 5, those that emit two wavelengths of B (blue) and UV (ultraviolet light) by using a UV-LED and a fluorescent material, or those composed only of UV-LEDs can also be used.

[0026] (3) In this case, the brightness and on / off timing of the multiple UV-LEDs (22, 23, 25) in the ultraviolet light range are set to operate in conjunction with the brightness and on / off timing of any of the multiple primary color LEDs (R, G, B), so that the control unit 3 can easily control the image while repelling pests.

[0027] (4) Alternatively, the brightness and on / off timing of multiple UV-LEDs (22, 23, 25) in the ultraviolet light range can be controlled independently of the brightness and on / off timing of multiple primary color LEDs (R, G, B), allowing the control unit 3 to set effective brightness and timing.

[0028] (5) Furthermore, since the control unit 3 displays video footage on the display unit 2 as images that repel pests, it is possible to repel pests more effectively than with still images. In addition, it is possible to suppress the pests becoming accustomed to the images.

[0029] (6) Furthermore, the control unit 3 displays images converted to a color space based on the color vision of the target pest on the display unit 2, which allows for more effective deterrence of the pest, and also suppresses the pest's habituation by changing the color space over time.

[0030] (7) In addition, the pest repellent device 1 further comprises an amplifier unit 61 and a speaker unit 62, and the control unit 3 is configured to emit a roar or intimidating sound from the speaker unit 62 in conjunction with the video, thereby further improving the repellent effect through the hearing of the pests.

[0031] (8) Furthermore, the pest repellent device 1 is further equipped with a laser light emitting unit 7, and the control unit 3 is configured to emit laser light from the laser light emitting unit 7 in conjunction with the video, thereby further improving the repellent effect through the pest's vision.

[0032] (9) Furthermore, the pest repellent device 1 is further equipped with a sensor unit 5 for detecting pests, and the control unit 3 displays an image on the display unit 2 in conjunction with the detection of pests by the sensor unit 5, thereby reducing power consumption. Moreover, since the image is displayed to the pests suddenly, the repellent effect can be further enhanced.

[0033] Although embodiments of the present invention have been described in detail above with reference to the drawings, the specific configuration is not limited to these embodiments, and any design modifications that do not depart from the spirit of the present invention are included in the present invention.

[0034] For example, in the embodiment, the sensor unit 5 was described as detecting pests, but it is not limited to this, and the video can be started at any time, or a switch can be provided to manually start the video.

[0035] Furthermore, although the embodiment was described as a pest repellent device 1 in the sense that it has the effect of repelling pests, it is not limited to this, and it is also possible to consider that a normal LED display has a configuration that repels pests. Alternatively, the present invention could be called a pest avoidance guidance device. In addition, in recent years, consideration has been required for collision accidents with wind turbine blades and windows of high-rise buildings (bird strikes), and the present invention is also effective as a bird strike countermeasure.

[0036] Furthermore, as shown in the modified example in Figure 4, the display unit 2A can also have multiple UV-LEDs 25, ... arranged on the outer frame (frame body 20) of the image area. In other words, instead of the UV-LEDs being arranged close to the primary color LED unit as in the embodiment, it is also possible to arrange multiple UV-LEDs 25, ... on the outer frame.

[0037] Although not explained in the examples, it is also possible to place a UV-reflective material in the same position as the UV-LED. [Explanation of Symbols]
