Description

  The present invention relates to a lighting apparatus having a function of capturing insects such as insects in an illumination space.

  Conventionally, a general lighting device that illuminates a living room such as a house has a configuration as shown in FIG. The general lighting fixture 90 includes a light source 91 that emits light for illuminating a living room, and a translucent member 92 called a globe, a panel, or a cover disposed on a part or the entire surface of the light source 91. ing. The translucent member 92 is provided for protection of the light source 91, control of the direction and wavelength of light emitted from the light source 91, or decoration. As the material of the light transmitting member 92, acrylic resin, styrene resin, polycarbonate resin, glass, or the like is used.

  By the way, insects have the habit of being attracted to light. For this reason, the insect 99 may fly in the vicinity of the general lighting fixture 90, and may give an unpleasant feeling to the person in the lighting space. In addition, the insect 90 may enter the inside of the general lighting device 90, and the insect 99 that has entered the general lighting device 90 may adversely affect the electrical components, thereby hindering the operation of the general lighting device 90, or the general lighting device 90. There is a possibility that the dead bodies of the insects 99 that have entered the device 90 accumulate on the inner surface of the translucent member 92 and impair the appearance of the general lighting device 90.

  Therefore, devices such as electric shock killers and adhesive insect traps that kill insects having such habits attracted by light are known. These instruments attract insects with an attracting light source that emits light that easily attracts insects (light in the vicinity of a wavelength of 360 [nm]), and kill the insects that approach the attracting light source with electric shock or adhesive paper.

  In addition, the general lighting device 90 may enter a portion where the insect 99 may enter, for example, a gap 94 or the like at a portion where the lighting device main body 93 holding the light source 91 and the translucent member 92 are combined. Insect 99 is prevented from entering by making it narrower than the size of insect 99.

In addition, there is known a lighting apparatus with an insect capturing function in which insects gathered by a light source are sucked by a suction force of a motor-driven rotating fan and captured in a collection bag (see, for example, Patent Document 1). .
JP 2001-155509 A

  However, in the above-mentioned electric shock insecticidal device, when an insect is killed by electric shock, an electric shock sound called “beeps” is generated, or insect dead bodies are scattered by electric shock. It will be lost. For this reason, the electric shock insecticide is not suitable for combined use with general lighting equipment. Further, in the above-described adhesive insect trap, the attracting light source emits pale light, and therefore, there is a possibility that the atmosphere of the illumination space is impaired when used with a general lighting fixture. For this reason, in order to use an adhesive insect trap in combination with a general lighting fixture, place the adhesive insect trap so that the light from the insect light source is difficult to see, or place the adhesive insect trap in an inconspicuous place, Care must be taken not to impair the atmosphere.

  Further, in the above-described conventional general lighting apparatus 90, when the translucent member 92 is not properly attached, the gap 94 between the lighting apparatus main body 93 and the translucent member 92 is more than necessary or If the light transmitting member 92 expands and contracts due to a change in the instrument temperature or the ambient temperature and the gap 94 or the like becomes large, the insect 99 can enter.

  Moreover, in the lighting instrument with an insect trapping function described in Patent Document 1 described above, a fan and a motor for driving the fan are necessary. Therefore, the structure of the instrument is complicated and the outer shape of the instrument is increased, and the appearance of the instrument is increased. And the appearance will be impaired.

  The present invention has been made in order to solve the above-described problems, and adds a trapping function for trapping pests in the lighting space without impairing the appearance and changing the atmosphere of the lighting space. An object of the present invention is to provide a lighting apparatus that reduces the invasion of pests into a site that impairs the appearance and function.

  In order to achieve the above object, the invention of claim 1 includes a light source, a translucent member that transmits light from the light source, and an insect capturing part having an opening into which an insect attracted by the light from the light source enters. The insect catching component is higher in the attracting property of the light transmitted through the catching component than the attracting property of the light transmitted through the translucent member, and on the mounting surface side of the lighting device. It is provided.

  In this configuration, since the catching parts are provided on the mounting surface side (the ceiling side, the wall side, etc., mainly opposite to the direction of illumination) of the lighting fixture, the insect catching from the side mainly illuminated by the lighting fixture. It is difficult to see the parts, so that the appearance and appearance of the lighting apparatus are not impaired. In addition, since the insect attractivity of the light transmitted through the insect trapping component is higher than the insect attractivity of the light transmitted through the light transmitting member, the insect is attracted to the light transmitted through the insect trapping component rather than the light transmitted through the light transmitting member. Attracted to insect trapping parts. Therefore, it is reduced that insects are attracted to the translucent member and enter the lighting fixture through the gap of the translucent member. The insect attracted to the insect trapping part enters the insect trapping part from the opening of the trapping part and is captured in the trapping part.

  According to a second aspect of the present invention, in the lighting apparatus according to the first aspect, the optical property of the insect capturing component is that the average transmittance between a wavelength of 250 [nm] and 410 [nm] is that of the translucent member. It is higher than the average transmittance.

  In this configuration, the trapping component transmits more light having a wavelength between 250 [nm] and 410 [nm] than the light transmitting member. Light having a wavelength between 250 [nm] and 410 [nm] has a high insecticidal property. Therefore, the insect is attracted more strongly to the light that passes through the catching part than the light that passes through the light projecting member, and is attracted more strongly to the catching part.

  According to a third aspect of the present invention, in the lighting device according to the first or second aspect, the insect capturing part has a bag-like structure having the opening, and the opening faces the outside of the lighting device. It is what.

  In this configuration, light from the light source is transmitted from the bag-shaped bottom side (opposite side to the opening) of the insect trapping part toward the opening. Therefore, the insect which invaded from the opening part of the insect trapping part is attracted to the light from the bag-like bottom part side toward the opening part side, and is attracted to the bag-like bottom part side. The insect attracted to the bag-like bottom side cannot be returned to the opening because it is attracted by light, and cannot enter the lighting apparatus, and stays in the bag-like bottom and is captured.

  According to a fourth aspect of the present invention, in the lighting apparatus according to any one of the first to third aspects, at least a part of the insect capturing part emits light having a wavelength of 250 [nm] to 410 [nm]. It is covered with a light shielding member.

  In this configuration, the light from the light source passes through the part not covered by the light shielding member of the insect capturing part. For this reason, an insect is attracted to the site | part which is not covered with the member which shields an insect trapping part. Therefore, for example, the opening and bottom of the insect trapping part (the end opposite to the opening) are not covered with a light shielding member, and the other parts are covered with a light shielding member so that the opening of the insect trapping part is covered. Insects can be attracted intensively, and insects that have entered through the opening can be attracted to the bottom and retained.

  According to a fifth aspect of the present invention, in the lighting apparatus according to any one of the first to fourth aspects, the opening part of the insect catching part is emitted from the light source and guides the inside of the insect catching part. It is made into the shape which regulates the direction of the light radiated | emitted from.

  In this structure, the insect in the radiation direction of the light from the opening of the insect capturing part is attracted to the opening. Therefore, by restricting the direction of light emission from the opening so as to be a direction in which there is a high possibility that the insect will fly, it becomes possible to efficiently attract the insect to the opening.

  According to a sixth aspect of the present invention, in the lighting device according to any one of the first to fifth aspects, the bottom part of the insect catching part is killed by heat radiated from the light source. In this way, it is arranged in the vicinity of the light source.

  In this configuration, insects that enter from the opening of the insect trapping part and stay at the bottom of the insect trapping part are killed by the heat radiated from the light source.

  A seventh aspect of the present invention is the lighting fixture according to any one of the first to sixth aspects, wherein the insect catching part has a structure in which insects cannot pass through except for the opening and has air permeability. is there.

  In this configuration, if the suction port of a vacuum cleaner or the like is applied to the opening of the insect trapping part and sucked, the insect trapping part has air permeability, so that the insect dead bodies collected in the insect trapping part together with the air from the opening of the trapping part Absorbed by a vacuum cleaner.

  According to an eighth aspect of the present invention, in the lighting apparatus according to any one of the first to seventh aspects, the insect trapping part has a structure in which at least a portion where the captured insect stays is detachable.

  In this configuration, the insect captured by the insect capturing component is removed by removing the portion where the captured insect stays. The part where the trapped insect stays is mounted again after the insect is removed or replaced with a new one.

  According to the first aspect of the present invention, since the insect trapping part is provided on the mounting surface side of the lighting fixture, a trapping function can be added without impairing the appearance of the lighting fixture or the atmosphere of the lighting space. In addition, since the insect attractivity of the light transmitted through the trapping component is higher than the attractivity of the light transmitted through the translucent member, the insect is attracted to and captured by the trap capturing component, thereby improving the appearance and function of the lighting fixture. Invasion of insects to damaged sites can be reduced.

  According to the invention of claim 2, the optical characteristics of the insect trapping component are such that the average transmittance between wavelengths of 250 [nm] to 410 [nm] is higher than the average transmittance of the translucent member. Insects are attracted more strongly to the parts, so that it is possible to more reliably reduce the invasion of insects into parts that impair the appearance and function of the luminaire, and to efficiently capture insects.

  According to the invention of claim 3, since the insect trapping part has a bag-like structure having an opening, and the opening faces the outside of the lighting device, the insect trapping part is trapped in the trapping part and the insect is reliably captured. be able to.

  According to the invention of claim 4, it is possible to efficiently capture insects by covering at least a part of the insect trapping parts with a member that blocks light having a wavelength of 250 [nm] to 410 [nm]. It becomes possible.

  According to the invention of claim 5, since the opening of the insect trapping part has a shape that regulates the direction of the light emitted from the opening, it is possible to efficiently capture the insect.

  According to the invention of claim 6, since the bottom part of the insect trapping part is arranged in the vicinity of the light source, the insect that has entered through the opening of the insect trapping part is killed by the heat radiated from the light source. Can be captured.

  According to the invention of claim 7, since the insect catching part cannot pass through the insects except for the opening and is breathable, the insect catching part can be easily removed by using a vacuum cleaner or the like. I can clean it.

  According to the invention of claim 8, since the part where the captured insect stays is detachable, the insect trapping part can be removed easily by removing the part where the captured insect stays, Insect catching parts can be easily cleaned.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments of the invention will be described with reference to the drawings.
<First Embodiment>
First, a first embodiment will be described with reference to FIGS. 1 (a) and 1 (b), FIG. 2, and FIG. The ceiling light 1 illuminates a living room such as a house, and is a lighting fixture that is used by being attached to a ceiling. The ceiling light 1 includes an instrument body 2, a fluorescent lamp 3 as a light source, a globe 4 as a translucent member, and three insect trapping parts 5, and the upper surface portion of the instrument body 2 is attached to the ceiling. The surface 21 is attached to the ceiling.

  The instrument main body 2 stores a control unit (not shown) that controls the lighting and extinguishing of the fluorescent lamp 3 and supports the fluorescent lamp 3 and the globe 4. The fluorescent lamp 3 emits light for illumination, is supported by the instrument body 2, and is disposed below the instrument body 2. Therefore, the ceiling light 1 mainly illuminates the side opposite to the mounting surface 21 side (that is, the ceiling side) with the light from the fluorescent lamp 3. The globe 4 transmits light from the fluorescent lamp 3, and is provided for protection of the fluorescent lamp 3, control of the direction and wavelength of light emitted from the fluorescent lamp 3, and decoration. The globe 4 is detachably attached to the instrument body 2 so as to cover the periphery of the fluorescent lamp 3.

  The insect trapping part 5 attracts and captures insects and other harmful insects, and is inserted into insertion holes (not shown) provided at three positions on the upper surface side of the globe 4 (that is, the mounting surface 21 side of the ceiling light 1). It is inserted and attached to the globe 4. This insect trapping part 5 has translucency and transmits light from the fluorescent lamp 3.

  The insect trapping part 5 is configured as shown in FIG. 2 and has a substantially cylindrical bag shape having an opening 51 into which an insect enters and having a closed end (bottom) opposite to the opening 51. Has the structure. The dimensions of the insect trapping part 5 are designed such that the length is approximately 60 [mm] and the outer diameter is 10 [mm]. In addition, the insect capturing part 5 has a flange 52 formed around the opening 51. The outer diameter of the flange 52 is designed to be 14 [mm]. Further, inside the insect catching component 5, a withdrawal limiter 60 that restricts the exit of the invading insect to prevent the captured insect from escaping from the opening 51 is disposed.

  The retreat restricting tool 60 is configured as shown in FIG. 3, and includes an annular ring member 61 and a plurality of guide pieces 62 connected to the ring member 61. The diameter of the retreat restricting tool 60 gradually decreases toward the front end side of the guide piece 62 because the front end side of each guide piece 62 is inclined toward the center of the ring member 61. The dimensions of the retreat restricting tool 60 are as follows: the outer diameter of the ring member 61 is 8 [mm], the diameter of the ring member 61 (the diameter of the proximal end of the guide piece 62) is 6 [mm], and the width of the ring member 61 is 1. The diameter of the guide piece 62 is designed to be about 4 [mm]. Each guide piece 62 is designed to have a flexible wall thickness so that insects can easily pass from the ring-shaped member 61 toward the distal end side of the guide piece 62.

  The insect trapping part 5 having such a configuration is inserted into the insertion hole (not shown) of the globe 4 in an oblique direction from the outside of the globe 4 toward the fluorescent lamp 3 and attached to the globe 4 (FIG. 1). (See (a) and (b)). In a state where the insect trapping part 5 is attached to the globe 4, the flange 52 is exposed at the upper portion of the globe 4, and the opening 51 is directed above the globe 4 (that is, outside the ceiling light 1). Further, the bottom of the insect trapping part 5 is located in the vicinity of the fluorescent lamp 3 so that insects staying at the bottom of the insect trapping part 5 (the end portion opposite to the opening 51) can be killed by the heat emitted from the fluorescent lamp 3. Placed in. The insect trapping part 5 is formed so that the outer diameter of the flange 52 is larger than the diameter of the insertion hole, and the flange 52 is held around the insertion hole and held by the globe 4. The insect trapping part 5 can be removed from the globe 4 by picking and pulling the flange 52.

  Further, in a state where the insect trapping part 5 is attached to the globe 4, the light from the fluorescent lamp 3 is transmitted through the insect trapping part 5 and radiated from the opening 51, and is guided through the constituent members of the insect trapping part 5. Radiated from the flange 52. The flange 52 has a shape that regulates the direction of light emitted from the flange 52 to a direction in which insects are highly likely to fly. The flange 52 emits light over a wide range in a substantially horizontal direction. It is like that.

  In general, insects have the habit of being attracted to light. The insect trapping part 5 transmits light having a higher attracting property than the light passing through the globe 4, so that the insect flying near the ceiling light 1 is attracted to the trapping part 5 and captured. I have to.

Next, the material and optical characteristics of the globe 4 and the insect capturing part 5 will be described. Table 1 shows the materials and optical characteristics of the globe 4 and the insect trapping part 5.

  The globe 4 is formed of an acrylic resin and has an average transmittance of 5% between a wavelength of 250 [nm] and 410 [nm]. On the other hand, the insect trapping part 5 is made of polyethylene resin, and has an average light transmittance of 60% between wavelengths of 250 [nm] and 410 [nm]. As described above, in the optical characteristics of the insect capturing component 5, the average transmittance of light between wavelengths of 250 [nm] to 410 [nm] is higher than the average transmittance of the globe 4. The retreat restricting tool 60 is formed of the same polyethylene resin as the insect trapping part 5 and has an average light transmittance of about 60% between wavelengths of 250 [nm] and 410 [nm].

  The attracting property that insects are attracted to light has a correlation with the wavelength of light, and light of wavelengths from 250 [nm] to 410 [nm] is greatly involved in attracting property. When there is much radiation of light with a wavelength from 250 [nm] to 410 [nm], the attractivity is high, and conversely, when there is little radiation of light with a wavelength from 250 [nm] to 410 [nm], the attractivity is Lower.

  As described above, in the optical characteristics of the insect capturing component 5, the average transmittance of light between wavelengths of 250 [nm] to 410 [nm] is higher than the average transmittance of the globe 4. Accordingly, light having a wavelength from 250 [nm] to 410 [nm] is emitted from the insect capturing component 5 more than the globe 4, and the attracting property of the light transmitted through the insect capturing component 5 is greater than that of the globe 4. It is higher than the insect attractivity of light passing through.

  With such a configuration, insects flying in the vicinity of the ceiling light 1 are attracted to the light transmitted through the insect capturing component 5 rather than the light transmitted through the globe 4 and are attracted to the opening 51 of the insect capturing component 5. At this time, since the light transmitted through the insect trapping part 5 is also emitted in the substantially horizontal direction from the flange 52 of the insect trapping part 5, the insect flying near the upper surface of the globe 4 is then emitted from the flange 52 in the substantially horizontal direction. The light is attracted to the opening 51 of the insect trapping part 5.

  Since the light transmitted through the insect trapping component 5 is emitted from the bottom side of the insect trapping component 5 (that is, the side where the fluorescent lamp 3 is located) toward the opening 51, the insect attracted to the opening 51 receives the light. It is attracted to enter the insect trapping part 5 from the opening 51 of the insect trapping part 5 and proceeds to the bottom side of the insect trapping part 5. Then, the insect passes through the retreat restricting device 60 and reaches the bottom of the insect capturing part 5 and is captured by the bottom of the insect capturing part 5. Insects captured at the bottom of the insect trapping part 5 are attracted by the light emitted from the bottom part side of the insect trapping part 5 toward the opening 51 side, and thus stay at the bottom part of the insect trapping part 5. Even after extinguishment, it is impossible to escape due to the retreat restricting tool 60, and eventually it is killed by the heat radiated from the fluorescent lamp 3.

  Insect carcasses captured by the insect catching component 5 are removed by removing the insect catching component 5 from the globe 4. At this time, the insect trapping part 5 is attached to the glove 4 again after removing and cleaning the insect carcasses, or is attached to the glove 4 by discarding the accumulated insect carcasses and replacing them with new ones. .

  According to the ceiling light 1 having such a configuration, since the insect catching component 5 is provided on the mounting surface 21 side (mainly opposite to the direction of illumination) of the ceiling light 1, the ceiling light 1 is mainly illuminated. The insect trapping part 5 is difficult to see from the side, and a trapping function can be added without impairing the appearance of the ceiling light 1 or the atmosphere of the illumination space. Moreover, since insects are attracted to and captured by the insect trapping part 5, it is possible to reduce the invasion of insects into sites that impair the appearance and function of the ceiling light 1, and by the insects entering the ceiling light 1. There is no hindrance to the operation, and insect dead bodies are accumulated on the inner surface of the globe 4 and the appearance of the ceiling light is not impaired.

  In addition, since the retraction restriction device 60 is provided inside the insect trapping part 5, it is difficult for the insects to escape, and the insects can be reliably captured. Moreover, the dead body of the insect captured by the insect trapping part 5 can be easily removed by removing the insect trapping part 5 from the globe 4 and the insect trapping part 5 can be easily cleaned.

<Second Embodiment>
Next, a second embodiment will be described with reference to FIGS. 4 (a) and 4 (b) and FIGS. 5 (a) and 5 (b). As in the first embodiment, the ceiling light 1 illuminates a living room such as a house, and is a lighting fixture that is used by being attached to a ceiling. The ceiling light 1 includes an instrument main body 2, two fluorescent lamps 3 as light sources, a globe 4 as a translucent member, and two insect capturing parts 5, and the first embodiment and Similarly, the upper surface portion of the instrument main body 2 is attached to the ceiling as the attachment surface 21 to the ceiling, and mainly illuminates the side opposite to the attachment surface 21 side (that is, the ceiling side).

  In the present embodiment, the insect catching component 5 is inserted into insertion holes (not shown) provided at two locations on the upper surface side of the instrument body 2 (that is, the attachment surface 21 side of the ceiling light 1). In the present embodiment, the structure of the insect trapping part 5 is different from that of the first embodiment. Furthermore, in this embodiment, the materials and optical characteristics of the globe 4 and the insect trapping part 5 are different from those of the first embodiment. Other configurations in the present embodiment are the same as those in the first embodiment.

  The insect trapping part 5 is configured as shown in FIGS. 5 (a) and 5 (b), has an opening 51 through which insects enter, and has a substantially cylindrical bag-like structure bent halfway. . The dimensions of the insect trapping component 5 are approximately 170 [mm] in total length, approximately 90 [mm] from the opening 51 to the bent portion, and the length from the bent portion to the end (bottom) on the opposite side of the opening 51. The length is designed to be approximately 80 [mm] and the outer diameter is 16 [mm]. In addition, the insect trapping part 5 has a flange 52 formed around the opening 51 and a retreat restricting tool 60 is arranged inside the opening 51 as in the first embodiment. The outer diameter of the flange 52 is designed to be 22 [mm]. The retreat restriction tool 60 has the same configuration as that of the first embodiment.

  In addition, the insect trapping component 5 is a light shielding element in which the area from the portion of the opening 51 excluding the flange 52 to the middle of the distal end side through the bent portion shields light having a wavelength of 250 [nm] to 410 [nm]. Covered with a material 53. Methods for covering with the light shielding material 53 include aluminum deposition, coating with black paint, wrapping aluminum foil, and the like. In this embodiment, aluminum deposition is performed on the surface of the insect catching component 5. The light shielding material 53 by aluminum vapor deposition is applied from the bent part of the insect capturing part 5 to the point of 35 [mm] from the end side. Further, the insect trapping part 5 has an air permeability by forming an opening 54 at the end (bottom) opposite to the opening 51 and disposing a mesh 55 having air permeability in the opening 54. Yes. The size of the holes in the mesh 55 is set to approximately 0.3 [mm] so that insects cannot pass through.

  The insect trapping part 5 having such a configuration is inserted into the insertion hole (not shown) of the instrument main body 2 from the bent portion of the insect trapping part 5 into the inside of the fluorescent lamp 3 from the outer side of the instrument main body 2 substantially vertically downward. And attached to the instrument body 2 (see FIGS. 4A and 4B). In a state where the insect trapping part 5 is attached to the instrument body 2, the opening 51 side is exposed to the upper part of the instrument body 2 from the bent part of the insect trapping part 5 and is arranged substantially horizontally, and the opening 51 is arranged in the outer peripheral direction of the instrument body 2 ( That is, it is directed toward the outside of the ceiling light 1. Since the area from the part excluding the flange 52 of the insect trapping part 5 to the middle of the end side through the bent portion is covered with the light shielding material 53, the part exposed to the upper part from the instrument body 2 of the insect trapping part 5 is the flange. The light shielding material 53 is covered except for 52. The bottom of the insect trapping part 5 is arranged in the vicinity of the fluorescent lamp 3 so that the staying insect can be killed by the heat emitted from the fluorescent lamp 3. Further, the insect trapping part 5 can be removed from the instrument body 2 by picking and pulling the opening 51 side (the part exposed from the instrument body 2) from the bent part.

  Further, in a state where the insect trapping part 5 is attached to the instrument main body 2, the light from the fluorescent lamp 3 is radiated through the insect trapping part 5. At this time, since the portion of the insect trapping part 5 exposed from the instrument body 2 is covered with the light shielding material 53 except for the flange 52, the light from the fluorescent lamp 3 is covered with the light shielding material 53. It is not radiated from the place but radiated only from the opening 51 and the flange 52. The flange 52 has a shape that regulates the direction of light emitted from the flange 52 to a direction in which insects are highly likely to fly. The flange 52 emits light over a wide range in a substantially horizontal direction. It is like that.

Next, the material and optical characteristics of the globe 4 and the insect capturing part 5 will be described. Table 2 shows the materials and optical characteristics of the globe 4 and the insect trapping part 5.

  The globe 4 is formed of an acrylic resin, and has an average light transmittance of 2% when the wavelength is between 250 [nm] and 410 [nm]. On the other hand, the insect trapping part 5 is made of polypropylene resin, and has an average light transmittance of 72% between wavelengths of 250 [nm] and 410 [nm]. As described above, in the optical characteristics of the insect capturing component 5, the average transmittance of light between wavelengths of 250 [nm] to 410 [nm] is higher than the average transmittance of the globe 4. The retraction restrictor 60 is formed of the same polypropylene resin as the insect trapping part 5 and has an average transmittance of about 72% from a wavelength of 250 [nm] to 410 [nm].

  With such a configuration, light having a wavelength of 250 [nm] to 410 [nm] is radiated more from the insect capturing component 5 than the globe 4. However, it is higher than the attractiveness of light transmitted through the globe 4. Therefore, insects flying in the vicinity of the ceiling light 1 are more attracted to light transmitted through the insect capturing component 5 than light transmitted through the globe 4. At this time, since the light transmitted through the insect trapping part 5 is emitted only from the opening 51 and the flange 52 as described above, insects flying in the vicinity of the ceiling light 1 are concentrated on the opening 51 of the insect trapping part 5. Be drawn to.

  The insect attracted to the insect trapping part 5 is captured at the bottom of the insect trapping part 5 and cannot stay out of the insect trapping part 5 and escapes from the fluorescent lamp 3 in the same manner as in the first embodiment. Die with heat.

  Insect carcasses captured by the insect trapping part 5 are removed, for example, by applying a suction port such as a vacuum cleaner to the opening 51 of the insect trapping part 5 while the insect trapping part 5 is attached to the instrument body 2 and sucking it. . When the suction port of a vacuum cleaner or the like is applied to the opening 51 and sucked, the mesh 55 at the bottom of the insect catching part 5 has air permeability, so that insect dead bodies collected in the insect catching part 5 are removed from the opening 51 together with air. Etc. Insect carcasses captured by the insect trapping part 5 may be removed by removing the insect trapping part 5 from the instrument body 2.

  According to the ceiling light 1 having such a configuration, the same operations and effects as those of the first embodiment can be obtained. Further, according to the ceiling light 1 having such a configuration, insects flying in the vicinity of the ceiling light 1 are intensively attracted to the opening 51 of the insect catching component 5, so that the insects can be efficiently captured. Insects captured by the insect trapping part 5 can be easily removed using a vacuum cleaner or the like without removing the insect trapping part 5 from the instrument body 2.

<Third Embodiment>
Next, a third embodiment will be described with reference to FIGS. 6 (a) and 6 (b) and FIG. The pendant light 1 illuminates a living room such as a house, and is a lighting fixture that is used by being attached to a ceiling. This pendant light 1 includes an instrument main body 2, a fluorescent lamp 3 as a light source, a panel 4 as a translucent member, and four insect capturing parts 5, and an upper surface portion of the instrument main body 2 is attached to the ceiling. The mounting surface 21 is suspended from the ceiling by a hanging tool (not shown).

  The instrument main body 2 stores a control unit (not shown) that controls the lighting and extinguishing of the fluorescent lamp 3, and supports the fluorescent lamp 3 and the panel 4. The fluorescent lamp 3 emits light for illuminating a living room such as a house, is supported by the instrument body 2, and is disposed below the instrument body 2. Therefore, the pendant light 1 mainly illuminates the side opposite to the mounting surface 21 side (that is, the ceiling side) with the light from the fluorescent lamp 3. Similar to the globes in the first and second embodiments, the panel 4 transmits light from the fluorescent lamp 3, protects the fluorescent lamp 3, and the direction and wavelength of the light emitted from the fluorescent lamp 3. Is provided for control and decoration. The lower side of the panel 4 is open.

  The insect trapping parts 5 are inserted into insertion holes (not shown) provided at four locations on the top plate 45 of the panel 4 (that is, the attachment surface 21 side of the pendant light 1). The insect trapping part 5 is configured as shown in FIG. 7, has an opening 51 into which an insect enters, and has a substantially cylindrical bag shape with a closed end (bottom) opposite to the opening 51. Has the structure. Further, the insect trapping part 5 has a fitting structure in which the insect retention part 56 on the end side can be attached and detached. In addition, the insect trapping part 5 has a flange 52 formed around the opening 51 and a retreat restricting tool 60 is arranged inside the opening 51 as in the first embodiment. The retreat restriction tool 60 has the same configuration as that of the first embodiment.

  The insect trapping part 5 having such a configuration is inserted into the insertion hole (not shown) of the top plate portion 45 of the panel 4 from the outside of the top plate portion 45 vertically downward to the inside of the fluorescent lamp 3, and the top plate portion 45 (see FIGS. 6A and 6B). In a state where the insect trapping part 5 is attached to the top plate portion 45, the flange 52 is exposed to the upper portion of the top plate portion 45, and the opening 51 is directed above the top plate portion 45 (that is, outside the pendant light 1). The bottom of the insect trapping part 5 is arranged in the vicinity of the fluorescent lamp 3 so that the staying insect can be killed by the heat emitted from the fluorescent lamp 3. The insect catching component 5 is formed such that the outer diameter of the flange 52 is larger than the diameter of the insertion hole, and the flange 52 is held around the insertion hole and held by the top plate portion 45. Further, the insect catching component 5 can be removed from the top plate portion 45 by picking and pulling the flange 52.

Further, in a state where the insect trapping part 5 is attached to the top plate part 45, the light from the fluorescent lamp 3 is radiated from the opening 51 and the flange 52. The flange 52 has a shape that regulates the direction of light emitted from the flange 52 to a direction in which insects are highly likely to fly. The flange 52 emits light over a wide range in a substantially horizontal direction. It is like that.

Next, the material and optical characteristics of the panel 4 and the insect trap 5 will be described. Table 3 shows the material and optical characteristics of the panel 4 and the insect trapping part 5.

  The panel 4 is formed of an acrylic resin, and has an average light transmittance of 2% between a wavelength of 250 [nm] and 410 [nm]. On the other hand, the insect trapping part 5 is formed of a material obtained by adding a white pigment to polypropylene resin, and has an average light transmittance of 53% from a wavelength of 250 [nm] to 410 [nm]. As described above, in the optical characteristics of the insect capturing component 5, the average transmittance of light between wavelengths of 250 [nm] to 410 [nm] is higher than the average transmittance of the panel 4.

  The insect trapping part 5 is made white by molding with a material in which a white pigment is added to polypropylene resin so that the inside of the insect trapping part 5 is not seen through. As the white pigment, silicon powder, glass powder, or the like having low ultraviolet absorption performance can be used. In this embodiment, silicon powder is added at 10 wt% with respect to the polypropylene resin. In addition, the retreat restricting tool 60 is formed of the same polypropylene resin as the insect trapping part 5 and has an average light transmittance of about 53% between wavelengths of 250 [nm] and 410 [nm].

  With such a configuration, light having a wavelength of 250 [nm] to 410 [nm] is radiated more from the insect capturing component 5 than the panel 4, and the light attracting light transmitted through the insect capturing component 5 is more attractive. However, it is higher than the attractiveness of the light transmitted through the panel 4. Therefore, insects flying in the vicinity of the pendant light 1 are attracted to the light that passes through the insect capturing component 5 rather than the light that passes through the panel 4. The insect attracted to the insect trapping part 5 is captured at the bottom of the insect trapping part 5 and cannot stay out of the insect trapping part 5 and escapes from the fluorescent lamp 3 in the same manner as in the first embodiment. Die with heat.

  Insect carcasses captured by the insect trapping part 5 are removed, for example, by removing the insect retention part 56 of the insect trapping part 5 while the insect trapping part 5 is attached to the instrument body 2. At this time, the insect retention part 56 of the insect trapping part 5 is attached to the insect trapping part 5 again after removing and cleaning the insect dead bodies, or discarding the accumulated insect dead bodies and replacing them with new ones. To be attached to the insect catching part 5. Insect carcasses captured by the insect trapping part 5 may be removed by removing the insect trapping part 5 from the top plate portion 452.

  According to the pendant light 1 having such a configuration, the same operations and effects as those of the first embodiment can be obtained. In addition, according to the pendant light 1 having such a configuration, the insect captured by the insect catching component 5 can be simply removed by removing the insect retaining portion 56 of the insect catching component 5 without removing the insect catching component 5 from the instrument body 2. Can be removed. In addition, since the lower side of the panel 4 is open, the insect catching component 5 can be seen from the lower side of the panel 4, but since the insect catching component 5 is white and the inside cannot be seen through, the insect catching component 5 is seen from the lower side of the panel 4. The captured insects cannot be seen, and the appearance of the pendant light 1 and the atmosphere of the lighting space are not impaired.
