Hereinafter, the lighting device 1 according to the present invention will be described with reference to the drawings. The lighting device 1 of the present embodiment emits light that irradiates lighting light that lights up at an output of 5% or more with respect to the peak output of 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. It has a part.

FIG. 1 shows an example of the lighting device 1 of the present embodiment.

The lighting device 1 of the present 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 blinking unit 11 that irradiates a blinking light in which the light source 10a blinks at a predetermined frequency when the switch is ON, and a lighting unit 12 that irradiates a lighting unit in which the light source 10a is constantly lit when the switch is ON. Have. As the light source 10a of the blinking unit 11 and the lighting unit 12, it is preferable to use a plurality of red, green, and blue LEDs, but other light sources 10a may be used.

The Electrical Appliance and Material Safety Law stipulates that the light output does not feel flicker when an LED is used as the light source 10a for general lighting. The lighting that does not make you feel flicker is either one that has a blinking unit 11 that blinks at a frequency of 100 Hz or higher and a lighting unit 12 that has no omission in the light output, or one that has only a blinking unit 11 that blinks at a frequency of 500 Hz or higher. Is recommended. The light emitting unit 10 of the present embodiment does not feel flicker so that it can be used even in a place where ordinary people enter.

FIG. 2 shows the relationship between the blinking frequency of the light and the number of insects caught. FIG. 3 shows an example of the output of the lighting device of the present embodiment.

As shown in FIG. 2, insects tend to collect in high frequency light. Therefore, from the viewpoint of insect repellent that does not collect insects, it is preferable that the blinking unit 11 blinks at a low frequency. Therefore, it is assumed that the light emitting unit 10 of the present embodiment has a blinking unit 11 that blinks at a frequency of 100 Hz or more and 500 Hz or less, and a lighting unit 12 that has no omission in the light output. Specifically, the light emitting unit 10 is a 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 a lighting unit that outputs 5% or more of the peak value of the optical output in the entire region of the light emitting unit 10. It has a part 12.

In this way, the light emitting unit 10 can prevent insects from gathering without making a person feel flicker by setting the blinking frequency of the blinking unit 11 to 100 Hz or more and 500 Hz or less. Further, it is more preferable that the blinking unit 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 unit 11 to 100 Hz or more and 150 Hz or less, it is possible to further prevent insects from gathering.

In the lighting device 1 of the present embodiment, the area of the lighting unit 12 is 5% or more of the total area of the light emitting unit 10 including the blinking unit 11 and the lighting unit 12 using a plurality of light sources 10a having the same output. do. For example, when LEDs having the same output are arranged at the same intervals as the light source 10a, the number of LEDs in the lighting unit 12 is 5% of the number of LEDs in the entire area of the light emitting unit 10 including the blinking unit 11 and the lighting unit 12. The above should be done. By setting the areas of the blinking unit 11 and the lighting unit 12 in this way, the output of the lighting unit 12 can be 5% or more of the output of the light emitting unit 10 including the blinking unit 11 and the lighting unit 12. ..

The output may be adjusted so that the output of the lighting unit 12 is 5% or more of the output of the entire area of the light emitting unit 10 including the blinking unit 11 and the lighting unit 12. Further, the output may be adjusted by a filter or the like, and the output of the lighting unit 12 may be 5% or more of the output of the entire area of the light emitting unit 10 including the blinking unit 11 and the lighting unit 12.

As shown in FIG. 1, the lighting device 1 of the present embodiment is provided with a lighting unit 12 so as to surround the blinking unit 11. With such a structure, the area illuminated only by the lighting unit 12 when the blinking unit 11 is off becomes large, and the lighting device 1 can effectively illuminate a place where ordinary people enter. can. Further, since the light sources 10a of the lighting unit 12 are arranged adjacent to each other, the wiring work of the lighting unit 12 of the lighting device 1 becomes easy.

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 arranged at the center or a part of the corner of the blinking unit 11. Further, the light source 10a of the lighting unit 12 may be arranged separately with a space between the light source 10a of the blinking unit 11.

The support portion 20 of the present embodiment is formed in a tripod shape. By forming in this way, the lighting device 1 of the present embodiment can be stably installed on a flat place such as the ground or the floor. Further, by making it possible to change the length of each of the tripod-shaped legs, the lighting device 1 can be stably installed even in a place other than a flat place such as a slope.

The support portion 20 may be formed in a shape other than a tripod. For example, in the lighting device 1, a light emitting portion 10 may be attached to the tip of a support portion 20 formed in a columnar shape, like a street lamp. Further, the support portion 20 may be configured to suspend the light emitting portion 10 from above. Further, the support portion 20 may be attached to another member such as a clip.

FIG. 4 shows the relationship between the color of the illumination and the number of insects caught. Specifically, it shows the ratio of the number of individuals captured by the color-coded LED when the number of individuals attracted and captured by ultraviolet rays is 1. The longer the bar graph, the larger the number of individuals captured.

As shown in FIG. 4, lizards, kochu, moths, caddisflies, and flies are most often captured by the blue light source 10a, and stink bugs and bees are most often captured by the green light source 10a. .. And all insects are the least captured by the red light source 10a. As described above, it can be seen that insects generally have a strong habit of gathering against ultraviolet rays and blue light, and have a low habit of gathering against red light.

Therefore, the lighting device 1 of the present embodiment uses light with a reduced blue component. However, since the lighting device 1 of the present embodiment is used in a place where ordinary people enter, it is preferable to reduce the blue component to the extent that there is no visual or mood inconvenience. Further, it is more preferable to bring it closer to red.

FIG. 5 shows an example of the light spectrum of the lighting device of the present embodiment. The horizontal axis is the wavelength and the vertical axis is the light intensity. FIG. 6 shows an example of arrangement of LEDs constituting the light source 10a of the lighting device of the present embodiment.

White light can be formed by synthesizing light of a blue component, a green component, and a red component. 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 the present embodiment emits light having a reduced relative intensity of the blue component as compared with white light.

The light emitted from the light emitting unit 10 of the lighting device 1 of the present embodiment has a peak wavelength of 600 nm or more and 750 nm or less. Here, the peak wavelength is the wavelength at which the emission intensity of light is maximized. When the relative intensity of the blue component is reduced, the light approaches red from yellow and orange. As shown in FIG. 4, the red light repels insects, so that the number of flying insects can be further reduced.

Since the lighting device 1 of the present embodiment is used in a place where ordinary people enter, the ratio of the relative intensity of the blue component is higher than that in the case of white light to the extent that there is no visual or mood inconvenience due to the surrounding environment or the like. You can reduce it. For example, by reducing the relative intensity of the blue component of the lighting device 1 as compared with the case of white light, the number of flying insects can be significantly reduced.

White light can be produced using LEDs of red, green, and blue, which are the three primary colors of light. When the blue component shown in FIG. 5 is a two-dot chain line spectrum, general white light is output. As shown in FIG. 6, the number of blue LEDs 10B per unit area of each of the blinking unit 11 and the lighting unit 12 of the lighting device 1 of the present embodiment may be smaller than the number of each of the red LED 10R and the green LED 10G.

As shown by the solid line shown in FIG. 5, the light emitting unit 10 emits light having a reduced intensity of the blue component as compared with white light. Light with reduced intensity of the blue component approaches red. Therefore, the number of flying insects can be significantly reduced. Further, a configuration in which the number of blue LEDs 10B per unit area is smaller than the number of each of the red LED 10R and the green LED 10G can be easily created from an LED light emitting device that outputs white light.

The reduction in the intensity of the blue component may be realized by reducing the output of the blue LED 10B. For example, in each of the blinking unit 11 and the lighting unit 12, the total output of the blue LED 10B may be smaller than the total output of the red LED 10R and the total output of the green LED 10G. If the total output of the blue LED 10B is smaller 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 LED 10R and the green LED 10G.

Further, the reduction in the intensity of the blue component may be realized by using a filter or the like. For example, the filter may change the wavelength of the light emitted by the blue LED 10B for a long time. By changing the wavelength of the light emitted by the blue LED 10B to a longer wavelength with a filter, it approaches red. Therefore, the number of flying insects can be significantly reduced.

Further, the number of each of the blue LED 10B and the green LED 10 per unit area of the blinking unit 11 and the lighting unit 12 of the lighting device 1 may be smaller than that of the red LED 10R. In addition, LEDs of other colors may be used.

Further, in order to realize white light, a blue LED 10B and a yellow phosphor may be used as the light source 10a. In this case, if the output of the blue component is reduced or the output of the yellow phosphor is increased, at least one of the blinking unit 11 or the lighting unit 12 emits light closer to red as compared with white light. can do. Therefore, the number of flying insects can be significantly reduced.

In the lighting device 1 of the present embodiment, the lighting unit 12 that is always lit is set to light in which the relative intensity of the blue component is reduced as compared with the white light, and the blinking unit 11 is appropriately set to light according to the surrounding environment. May be good. For example, the peak wavelength of the lighting unit 12 may be red of 600 nm or more and 750 nm or less, and white light or light having a peak wavelength of less than 600 nm and larger than 750 nm may be applied to the blinking unit 11. 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 with respect to the light emitting unit 10.

In this way, the user sets the blinking portion 11 having a large area having an influence on the surroundings to the light suitable for the surrounding environment, and reduces the relative intensity of the blue component in the lighting portion 12 as compared with the white light. Can be set to light. Therefore, the amount of insect attracted can be reduced while ensuring the color rendering property to the surroundings.

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

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

In this way, by making the lighting unit 12 light in which the relative intensity of the blue component is reduced as compared with the white light, it is possible to further suppress the arrival of insects.

Further, the light emitting unit 10 of the lighting device 1 of the present embodiment does not need to clearly separate the locations of the blinking unit 11 and the lighting unit 12. For example, the entire region 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 region may be irradiated with blinking light. When the blinking light is emitted by at least a part of the light source 10a of the light emitting unit 10, the light source 10a to irradiate the blinking light may be set in advance or may be controlled so as to be randomly selected each time the light is emitted. ..

For example, the light emitting unit 10 may output the entire region in a sine and cosine shape between an output of 5% or more and an output of 100% with respect to the peak output. That is, the light emitting unit 10 constantly irradiates the lighting light at an output of 5% or more with respect to the peak output in the entire region, and blinks a sine-shaped output between the output of 5% or more with respect to the peak output and the output of 100%. Irradiate. The current of the light source 10a is controlled by a capacitor, and the output may be adjusted.

Further, the light emitting unit 10 of the present embodiment adjusts the duty ratio of each light source 10a so that the lighting light is lit at an output of 5% or more with respect to the peak output of the entire region and 100 Hz or more and 500 Hz or less in at least a part region. You may irradiate a blinking light that blinks at the frequency of.

For example, the light emitted by the light source 10a in the light emitting unit 10 may be output with a constant peak value in the entire region. In this case, the lighting time of each of the light sources 10a is controlled, and the output per unit time is adjusted. The light source 10a that irradiates the lighting light or the blinking light may be set in advance, or may be controlled so that it can be randomly selected each time the light is emitted.

As described above, the lighting device 1 of the present embodiment irradiates the lighting light that lights up at an output of 5% or more with respect to the peak output of the entire region and the 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. It is provided with a light emitting unit. Therefore, it is possible to reduce the number of flying insects without causing discomfort to humans.

Further, 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 smaller output than the red LED 10R and the green LED 10G, respectively. Therefore, it is energy-saving, has a long life, and can reduce the number of flying insects.

Further, in the lighting device 1 of the present 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.
