FIG. 1 is a diagram showing an embodiment of a flickering insect repellent lighting device and an insect repelling method according to the present invention. FIG. 2 is an explanatory diagram of a blinking pattern according to the present embodiment. (1) is pattern 1, (2) is pattern 2, and (3) is pattern 3.

  Hereinafter, embodiments of a flicker-type insect repellent lighting device and an insect repellent method according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Blinking insect-proof lighting system)
First, an embodiment of a blinking insect repellent lighting device according to the present invention will be described.

  As shown in FIG. 1, a flickering insect repellent lighting device 10 according to the present embodiment is a device that irradiates a flickering light F having an effect of repelling insects to an insect repellent target area A. The flickering insect repellent lighting device 10 includes a light source support 16 provided at the tip of an arm 14 projecting obliquely upward from above the support 12, a plurality of light sources 18 supported by the light source support 16, and a support 12. And a light source control unit 20 (light source control means) provided below the light source.

  The light source support 16 is formed of a substrate whose upper part is covered with a protective cover. The substrate is provided on the lower surface of the light source support 16, and a plurality of light sources 18 are arranged on the substrate. As shown in FIG. 2A, the plurality of light sources 18 are arranged close to each other in the form of a lattice point in a front view (a bottom view). As shown in FIG. 1, each light source 18 is capable of irradiating the flickering light F at a predetermined frequency toward the insect-controlling target area A below.

  Each light source 18 is configured by an LED element (light emitting diode element). For this reason, irradiation of blinking light for a long time can be performed with power saving. In addition, the time and effort for replacement can be reduced as much as possible, and insects can be effectively repelled with a small amount of power consumption. Furthermore, by arranging a plurality of LED elements on a substrate and using it as a light source as an LED substrate, manufacturing and assembly can be easily performed. By arranging the LED elements collectively on the LED board, wiring and power supply can be facilitated, and the appearance can be improved.

  The light source control unit 20 changes the light emission state of each light source 18, and is connected to each light source 18 via a wired or wireless type input / output line (not shown). The light source control unit 20 includes an operation unit for setting a light emission state of each light source 18 and a circuit unit for outputting a signal input to the operation unit to each light source 18.

  The operation unit is provided with operation switches for controlling the blinking cycle (or frequency), the lighting time, and the light-off time of each light source 18. When the blinking cycle (or frequency), lighting time, and turning-off time of each light source 18 are set by the operation unit, a signal corresponding to the set value is generated, and this signal is output to each light source 18 via the circuit unit. The light emitting state (flashing state) of each light source 18 is controlled.

The operation and operation of the above configuration will be described.
The blinking light F is emitted from the plurality of light sources 18 so as to exert an effect of repelling insects such as night moths and the like that are present in the insect repellent target area A. More specifically, each light source 18 emits light having a predetermined light emission intensity so as to be repeatedly turned on and off at a predetermined blinking cycle. The flickering light F can confuse the insects and prevent attraction to the light source 18. Here, the light source control unit 20 controls the light sources 18 so that the plurality of light sources 18 as a whole are recognized as continuous light by human eyes by sequentially blinking the light sources 18 in a predetermined combination. In this way, even if the light from the light source 18 enters the eyes, the repelling effect by the blinking light F can be exerted without giving any discomfort to the person.

  The blinking frequency of each light source 18 is preferably 20 Hz or more. If the blinking frequency is smaller than this range, that is, if the blinking cycle is long, it is not preferable because a person may feel uncomfortable.

  The emission intensity of the light source 18 can be appropriately set to a value that can exert a repellent effect according to the type of insect to be controlled and the distance to the insect. Further, the emission wavelength of the light source 18 can be appropriately set according to the type of insect to be controlled, which exhibits phototacticity.

  The blinking light having a frequency of less than 20 Hz is generally light that may make a person feel uncomfortable. However, since the light source 18 as a whole is recognized as continuous light by the human eye, it is unpleasant to humans. It is not light that makes you feel. Therefore, the flickering light F emitted from the light source 18 does not make the person feel uncomfortable and confuses insects such as night moths and the like that are in the insect repellent target area A and intrudes into the light source 18 and attracts them to the light source 18. Can be prevented.

  Alternatively, as the plurality of light sources 18, light sources that blink at a predetermined frequency (for example, 70 Hz) may be arranged alternately, and the light sources may be controlled so that the blinking intervals are alternated. In this way, either light source is turned on, so it seems to the human eye to be lit continuously, but the insects are confused by the blinking light and are attracted to the light source Is gone.

  The blinking interval is recognized as continuous light by human eyes if, for example, the time from when one light source is turned off to when the other light source is turned on next time among the light sources arranged alternately is set to zero. However, the light may be turned on next after an interval shorter than 20 Hz that cannot be detected by humans. In this way, the repellent effect on insects can be enhanced without causing discomfort to humans.

  In this manner, the time interval between turning off one set of light sources 18 arbitrarily set out of the plurality of light sources 18 and turning on the other combination of light sources 18 next time is zero or a time interval of 20 Hz or more. If the lights are sequentially turned on and off, the time interval between turning off the light and turning on the light next time is so short that a person does not feel discomfort. For this reason, an excellent insect repellent effect can be exhibited without causing a person to feel discomfort.

(Example)
Next, an embodiment of the present invention will be described with reference to FIG. FIG. 2 shows an example of a blinking pattern by the light source control unit 20. It should be noted that what is shown in the figure is merely an example, and does not limit the combination of blinking lights that does not cause discomfort to a person.

  The pattern 1 in FIG. 2A repeats the ON state of 1, the OFF state of 2, the ON state of 3, and the ON state of 3 in this order. Adjacent light sources 18 alternately flash with the two OFF states (all unlit). For example, 1 (ON state) at a flash start time (0 second), 2 (OFF state) at a predetermined time (for example, after 0.07 seconds), and further time (e.g., 0.14 seconds after) ), The lighting state of each light source 18 is switched to 3 (ON state), and so on. In this case, the blinking cycle is 0.21 seconds (lighting time 0.07 seconds, light-off time 0.14 seconds). With this configuration, the entire light source can be recognized as continuous light by human eyes. Therefore, the insect repellent effect can be exhibited without giving any discomfort to the person.

  The pattern 2 in FIG. 2B is a pattern in which the adjacent light sources 18 are alternately turned on and off, and the states 1 to 3 are repeated. For example, a state of 1 at the start of blinking (0 second), a state of 2 at a predetermined time (eg, after 0.07 seconds), and a state of 3 at a predetermined time (eg, 0.14 seconds). The lighting state of each light source 18 is switched in a state (the same state as 1),... In this case, the blinking period is 0.14 seconds (lighting time 0.07 seconds, light-off time 0.07 seconds). With this configuration, the entire light source can be recognized as continuous light by human eyes. Therefore, the insect repellent effect can be exhibited without giving any discomfort to the person.

  Pattern 3 in FIG. 2 (3) is one in which all the light sources 18 are turned on and off at the same time, and the states 1 to 3 are repeated. For example, at the start of blinking (0 second), the ON state of 1 (all lights up), at the time of a predetermined time (for example, after 0.07 seconds), at the state of 2 (all light off), and at the time of a further predetermined time (eg, At 0.14 seconds), the lighting state of each light source 18 is switched, for example, the ON state of 3 (all lighting),. In this case, the blinking cycle is 0.14 seconds (lighting time 0.07 seconds, light-off time 0.07 seconds). Even with such a blinking pattern, if the entire light source can be recognized as continuous light by human eyes, the insect repellent effect can be exerted without giving any discomfort to the human.

  The number of the light sources 18, the arrangement positions of the light sources 18, the blinking patterns, and the like described in the above embodiment are merely examples, and the present invention is not limited to this example and can be set arbitrarily. The LED elements used for the light source 18 do not necessarily need to be arranged in the form of lattice points on the substrate of the light source support 16 and can be arranged in any shape. Further, the light source 18 is not limited to the LED element, but may use other types of light sources such as a fluorescent lamp or a combination of a plurality of types of light sources.

  In the above-described embodiment, the directivity is provided so that the light emitted from the light source 18 is directed downward. However, the connection between the arm 14 and the light source support 16 may have a rotatable joint structure. . By doing so, the direction of the light emitted from the light source 18 can be changed by adjusting the angle of the light source support 16.

  Further, in the above-described embodiment, the case where the insect-controlling target area A is set below the light source support 16 has been described as an example. However, the present invention is not limited to this. , Or on the side. When the insect repellent target area A is set above the light source support part 16, the direction of the light source support part 16 is set so that the light emitted from the light source 18 is directed upward, and the insect repellent target area A is set next to the light source support part 16. When set to the side, the direction of the light source support 16 may be set such that the light emitted from the light source 18 is oriented horizontally.

  Further, in the above embodiment, the lower surface side of the substrate of the light source support 15 may be covered with a light-transmitting and weather-resistant cover such as acrylic. The cover may be made of a material capable of diffusing the light from the light source 18 or may be formed of a material capable of diffusing the light.

  Further, in the above embodiment, when each of the light sources 18 is controlled to blink, it is not necessary to create a completely unlit state. The light emission luminance of the light source 18 may be periodically increased or decreased to control as if it were blinking. Even in this case, the same operation and effect as described above can be obtained.

(Insect control method)
Next, an embodiment of the insect control method according to the present invention will be described.

  As shown in FIG. 1, the insect repelling method according to the present embodiment is a method for irradiating the insect repelling target area A with a flickering light F having an effect of repelling the insects. The plurality of light sources 18 that emit the blinking light F at a predetermined frequency toward the insect repellent target area A are sequentially blinked in a predetermined combination, so that the plurality of light sources 18 as a whole are recognized as continuous light by human eyes. . According to the present embodiment, it is possible to obtain the same operation and effect as those of the above-mentioned blinking insect repellent lighting device 10. In other words, even if the light from the light source 18 enters the eyes, the insect repellent effect can be exhibited without giving any discomfort to the person.
