[0016] Hereinafter, an illumination device 1 according to an embodiment of the present invention will be described with reference to the drawings. The illumination device 1 of this embodiment includes a light-emitting unit that emits lighting light that is turned on at an output of 5% or more of the peak output in the entire region, and blinking light that blinks at a frequency of 100 Hz or more and 500 Hz or less in at least a part of the region.

[0017] FIG. 1 shows an example of a lighting device 1 according to the present embodiment.

[0018] The lighting device 1 of this embodiment includes a light-emitting unit 10 having a light source 10a that emits light, and a support unit 20 that supports the light-emitting unit 10. The light-emitting unit 10 includes a flashing unit 11 that irradiates flashing light in which the light source 10a flashes at a predetermined frequency when the switch is ON, and a lighting unit 12 that irradiates lighting light in which the light source 10a is constantly lit when the switch is ON. The light sources 10a of the flashing unit 11 and the lighting unit 12 are both preferably made of multiple red, green, and blue LEDs, but may be other light sources 10a.

[0019] The Electrical Appliance and Material Safety Law stipulates that when LEDs are used as the light source 10a for general lighting, the light output must not flicker. It is recommended that lighting that does not flicker is either one that has a flashing part 11 that flashes at a frequency of 100 Hz or more and a lighting part 12 with no loss in light output, or one that has only a flashing part 11 that flashes at a frequency of 500 Hz or more. The light-emitting part 10 of this embodiment does not flicker so that it can be used in places where the general public enters.

[0020] Fig. 2 shows the relationship between the frequency of blinking of the light and the number of captured insects. Fig. 3 shows an example of the output of the lighting device of this embodiment.

[0021] As shown in FIG. 2, insects tend to be attracted to light with a high frequency. Therefore, from the viewpoint of insect control that does not attract insects, it is preferable that the blinking unit 11 blinks at a low frequency. Therefore, the light-emitting unit 10 of this embodiment has the blinking unit 11 that blinks at a frequency of 100 Hz or more and 500 Hz or less, and the lighting unit 12 that has no loss in light output. Specifically, the light-emitting unit 10 has the blinking unit 11 that blinks at a frequency of 100 Hz or more and 500 Hz or less in at least a part of the region, and the lighting unit 12 that outputs at 5% or more of the peak value of the light output of the entire region of the light-emitting unit 10.

[0022] In this way, by setting the blinking frequency of the blinking portion 11 of the light-emitting portion 10 to 100 Hz or more and 500 Hz or less, people can avoid flickering and insects can be prevented from gathering. It is more preferable that the blinking portion 11 blinks at a frequency of 100 Hz or more and 150 Hz or less. In this way, by setting the frequency of the blinking portion 11 to 100 Hz or more and 150 Hz or less, insects can be further prevented from gathering.

[0023] In the lighting device 1 of this embodiment, the area of ​​the lighting section 12 is set to 5% or more of the total area of ​​the light-emitting section 10, which is the sum of the blinking section 11 and the lighting section 12 using multiple light sources 10a with the same output. For example, when LEDs with the same output are arranged at equal intervals as the light sources 10a, the number of LEDs in the lighting section 12 may be set to 5% or more of the total number of LEDs in the total area of ​​the light-emitting section 10, which is the sum of the blinking section 11 and the lighting section 12. By setting the areas of the blinking section 11 and the lighting section 12 in this manner, the output of the lighting section 12 can be set to 5% or more of the total output of the light-emitting section 10, which is the sum of the blinking section 11 and the lighting section 12.

[0024] The output may be adjusted so that the output of the lighting unit 12 is 5% or more of the output of the entire region of the light-emitting unit 10, which includes the flashing unit 11 and the lighting unit 12. Furthermore, the output may be adjusted by a filter or the like so that the output of the lighting unit 12 is 5% or more of the output of the entire region of the light-emitting unit 10, which includes the flashing unit 11 and the lighting unit 12.

[0025] 1, the lighting device 1 of this embodiment is provided with the lighting unit 12 surrounding the blinking unit 11. With this structure, the area illuminated only by the lighting unit 12 when the blinking unit 11 is turned off becomes large, and the lighting device 1 can effectively illuminate places where general public enters. In addition, since the light sources 10a of the lighting unit 12 are arranged adjacent to each other, the wiring work for the lighting unit 12 of the lighting device 1 becomes easy.

[0026] The lighting device 1 may have a structure other than that in which the lighting unit 12 surrounds the blinking unit 11. For example, the lighting unit 12 may be disposed in a part such as the center or a corner of the blinking unit 11. Furthermore, the light sources 10a of the lighting unit 12 may be disposed separately between the light sources 10a of the blinking unit 11 with intervals therebetween.

[0027] The support 20 of this embodiment is formed in a tripod shape. By forming it in this way, the lighting device 1 of this embodiment can be stably installed on a flat place such as the ground or a floor. In addition, by making the length of each leg of the tripod shape changeable, the lighting device 1 can be stably installed even on a place other than a flat place such as a slope.

[0028] The support unit 20 may be in a shape other than a tripod. For example, the lighting device 1 may have the light-emitting unit 10 attached to the tip of the support unit 20 formed in a pillar shape, like a street lamp. The support unit 20 may also be configured to suspend the light-emitting unit 10 from above. Furthermore, the support unit 20 may be attached to another member, like a clip.

[0029] Figure 4 shows the relationship between lighting color and the number of insects captured. Specifically, it shows the ratio of the number of insects captured by different colored LEDs to the number of insects attracted and captured by UV light set at 1. The longer the bar, the more insects were captured.

[0030] 4, the number of mayflies, bumblebees, moths, caddisflies, and flies captured is greatest by the blue light source 10a, while the number of stink bugs and bees captured is greatest by the green light source 10a. And the number of all insects captured is least by the red light source 10a. Thus, it can be seen that, in general, insects have a strong tendency to be attracted to ultraviolet light and blue light, and are less likely to be attracted to red light.

[0031] Therefore, the lighting device 1 of this embodiment uses light with a reduced blue component. However, since the lighting device 1 of this embodiment is used in a place where general public enters, it is preferable to reduce the blue component to an extent that does not cause visual or emotional inconvenience. It is more preferable to make the color closer to red.

[0032] Fig. 5 shows an example of the spectrum of light from the lighting device of this embodiment. The horizontal axis represents wavelength, and the vertical axis represents light intensity. Fig. 6 shows an example of the arrangement of LEDs constituting the light source 10a of the lighting device of this embodiment.

[0033] White light can be formed by combining blue, green, and red light components. The wavelength of the blue component is about 450-480 nm, the wavelength of the green component is about 500-560 nm, and the wavelength of the red component is about 620-750 nm. The lighting device 1 of this embodiment emits light in which the relative intensity of the blue component is reduced compared to white light.

[0034] The light emitted from the light-emitting unit 10 of the lighting device 1 of this embodiment has a peak wavelength of 600 nm or more and 750 nm or less. Here, the peak wavelength refers to the wavelength at which the light emission intensity is maximum. When the relative intensity of the blue component is reduced, the light approaches red from yellow or orange. As shown in FIG. 4, red light does not attract insects, so the number of flying insects can be further reduced.

[0035] Since the lighting device 1 of the present embodiment is used in places where general public enters, it is sufficient to reduce the relative intensity of the blue component compared to that of white light to an extent that does not cause visual or emotional inconvenience depending on the surrounding environment, etc. For example, by reducing the relative intensity of the blue component of the lighting device 1 compared to that of white light, the number of flying insects can be significantly reduced.

[0036] White light can be created using red, green, and blue LEDs, which are the three primary colors of light. When the blue component shown in Fig. 5 has a spectrum of a two-dot chain line, general white light is output. The number of blue LEDs 10B per unit area of ​​each of the flashing section 11 and the lighting section 12 of the lighting device 1 of this embodiment should be less than the number of red LEDs 10R and green LEDs 10G, as shown in Fig. 6.

[0037] The light-emitting unit 10 emits light in which the intensity of the blue component is reduced compared to white light, as shown by the solid line in FIG. 5. Light in which the intensity of the blue component is reduced approaches red. Therefore, the number of flying insects can be significantly reduced. Also, a configuration in which the number of blue LEDs 10B per unit area is less than the number of red LEDs 10R and green LEDs 10G can be easily created from an LED light-emitting device that outputs white light.

[0038] The reduction in the intensity of the blue component may be realized by reducing the output of the blue LEDs 10B. For example, the total output of the blue LEDs 10B may be less than the total output of the red LEDs 10R and the total output of the green LEDs 10G in each of the flashing unit 11 and the lighting unit 12. If the total output of the blue LEDs 10B is less than the total output of each of the other colors, the number of blue LEDs 10B per unit area may be the same as that of the red LEDs 10R and the green LEDs 10G.

[0039] The reduction in the intensity of the blue component may be achieved by using a filter or the like. For example, the filter may be one that changes the wavelength of the light emitted by the blue LED 10B to a longer wavelength. By changing the wavelength of the light emitted by the blue LED 10B to a longer wavelength using a filter, the wavelength approaches red. Therefore, the number of flying insects can be significantly reduced.

[0040] Furthermore, the number of blue LEDs 10B and green LEDs 10 per unit area of ​​each of the flashing portion 11 and the lighting portion 12 of the lighting device 1 may be less than the number of red LEDs 10R. Furthermore, LEDs of other colors may be used.

[0041] Also, to realize white light, a blue LED 10B and a yellow phosphor may be used as the light source 10a. In this case, by reducing the output of the blue component or increasing the output of the yellow phosphor, at least one of the flashing unit 11 or the lighting unit 12 can emit light closer to red than white light. Therefore, the number of flying insects can be significantly reduced.

[0042] In the lighting device 1 of this embodiment, the constantly lit lighting section 12 may be set to light with a reduced relative intensity of the blue component compared to white light, and the flashing section 11 may be set to light according to the surrounding environment. For example, the lighting section 12 may be set to red with a peak wavelength of 600 nm or more and 750 nm or less, and the flashing section 11 may be set to white light or light with a peak wavelength of less than 600 nm and more than 750 nm. The method of reducing the relative intensity of the blue component may be the same as the method of reducing the relative intensity of the blue component for the light-emitting section 10.

[0043] In this way, the user can set the flashing section 11, which has a large area that affects the surroundings, to a light that is suitable for the surrounding environment, and set the lighting section 12 to a light that has a reduced relative intensity of blue components compared to white light. Therefore, the amount of insects attracted can be reduced while maintaining color rendering for the surroundings.

[0044] For example, Table 1 shows the results of an insect attraction test when the flashing section 11 is white light and the lighting section 12 is white light or red light with a peak wavelength of 600 nm or more and 750 nm or less. In the insect attraction test, adhesive paper was attached to the entire surface of the light-emitting section 10 shown in Figure 1, the light-emitting section 10 was turned on outdoors, and the number of insects captured by the adhesive paper was counted. [Table 1]

[0045] As shown in Table 1, in all three tests, the number of insects captured was smaller when the lighting portion 12 was red.

[0046] In this way, by using light having a reduced relative intensity of blue components compared to white light from the lighting section 12, it is possible to further suppress the influx of flying insects.

[0047] Furthermore, the light-emitting unit 10 of the lighting device 1 of this embodiment does not need to clearly separate the locations of the flashing unit 11 and the lighting unit 12. For example, the entire area of ​​the light-emitting unit 10 may be constantly irradiated with lighting light of 5% or more of the peak output, and at least a part of the area may be irradiated with flashing light. When flashing light is irradiated from at least a part of the light sources 10a of the light-emitting unit 10, the light sources 10a that irradiate the flashing light may be set in advance, or may be controlled so as to be selected randomly each time light is emitted.

[0048] For example, the light-emitting unit 10 may output a sine wave between 5% or more of the peak output and 100% of the peak output in the entire region. In other words, the light-emitting unit 10 constantly emits a lighting light with an output of 5% or more of the peak output in the entire region, and emits a blinking light with a sine wave output between 5% or more of the peak output and 100% of the peak output. The light source 10a may have a current controlled by a capacitor to adjust the output.

[0049] In addition, the light-emitting unit 10 of this embodiment may adjust the duty ratio of each light source 10a to emit a lighting light that is lit at an output of 5% or more of the peak output in the entire region and a flashing light that flashes at a frequency of 100 Hz or more and 500 Hz or less in at least some regions.

[0050] For example, the light emitted by the light source 10a in the light-emitting unit 10 may be output at a constant peak value in all regions. In this case, the light source 10a is controlled for its lighting time, and the output per unit time is adjusted. The light source 10a that emits lighting light or blinking light may be set in advance, or may be controlled so as to be randomly selected each time light is emitted.

[0051] As described above, the lighting device 1 of the present embodiment includes a light-emitting unit that emits lighting light with an output of 5% or more of the peak output in the entire region and flashing light with a frequency of 100 Hz to 500 Hz in at least a part of the region. Therefore, the number of flying insects can be reduced without causing discomfort to people.

[0052] In the lighting device 1 according to the present invention, the lighting light is light in which the relative intensity of the blue component is reduced compared to white light, which can further inhibit the influx of flying insects.

[0053] Furthermore, in the lighting device 1 of this embodiment, the peak wavelength of the illumination light is not less than 600 nm and not more than 750 nm, which can further reduce the number of flying insects.

[0054] In addition, in the lighting device 1 of the present embodiment, the light source 10a of the light-emitting unit 10 includes a red LED 10R, a green LED 10G, and a blue LED 10B, and the blue LED 10B has a lower output than the red LED 10R and the green LED 10G. Therefore, it is energy-efficient, has a long life, and can reduce the number of flying insects.

[0055] In addition, in the lighting device 1 of this embodiment, the light-emitting unit 10 has a blinking unit 11 that blinks at a specific frequency and a lighting unit 12 that is constantly lit. Therefore, the lighting device 1 can be realized at low cost with a simple structure.

[0056] In addition, in the lighting device 1 of this embodiment, the lighting unit 12 is formed around the flashing unit 11. Therefore, the area illuminated only by the lighting unit 12 when the flashing unit 11 is turned off becomes large, and the lighting device 1 can effectively illuminate places where general public enters. In addition, since the light sources 10a of the lighting unit 12 are arranged adjacent to each other, the wiring work for the lighting unit 12 of the lighting device 1 becomes easy.

[0057] Furthermore, in the lighting device 1 of this embodiment, the blinking light is adjusted by the duty ratio. Therefore, the lighting device 1 can efficiently use the power supply components and reduce the waste of electricity.

[0058] Furthermore, in the lighting device 1 of this embodiment, the steady light and blinking light are output at a constant peak value, so the lighting device 1 can be easily controlled.

[0059] It should be noted that the present invention is not limited to the embodiments, and that although many specific details are included for illustrative purposes in the description of the embodiments, those skilled in the art may make various variations and modifications to these details.
