Description

This disclosure relates to a lamp equipped with a repellent member that repels insects, a device to which the lamp is attached, and a lighting device equipped with the lamp and the device.

Illumination devices that are attached to a mounting portion such as a ceiling or a wall have been known for some time. For example, the lighting fixture disclosed in Patent Document 1 has a light source unit that irradiates light, and a fixture body that is fixed to a mounting portion such as a ceiling or a wall and to which the light source unit is attached. The light source unit has a mounting member formed in an elongated shape, a light source portion that is attached to the mounting member, and a translucent cover that is attached to the mounting member so as to cover the light source portion. The light source portion is disposed in an internal space surrounded by the cover and the mounting member.

In lighting devices, insects may get into the gap between the cover member and the mounting member, and may then accumulate in the internal space enclosed by the cover and mounting member. In lighting fixtures, if insects accumulate in the internal space enclosed by the mounting member and cover, the insects will be visible from the outside, significantly compromising the appearance. In addition, in lighting fixtures, the accumulated insects may block the light passing through the cover, reducing the transmittance. Furthermore, if insects attach to the light source section, etc., this may cause parts to deteriorate or malfunctions such as short circuits, compromising safety.

Therefore, in the lighting fixture of Patent Document 1, an elastic member is provided between the cover and the mounting member to tightly seal them together, preventing insects from getting in between the cover member and the mounting member.

Patent No. 6489469

However, in the lighting fixture disclosed in Patent Document 1, insects may elastically deform the elastic member to form a small gap and enter the internal space enclosed by the mounting member and the cover.

The present disclosure has been made to solve the above problems, and aims to provide a lamp, device, and lighting apparatus that can prevent insects from entering the space in which the light source unit is located.

The lighting fixture of the present disclosure comprises a long, box-shaped first outer casing having a translucent irradiation surface and an opening surface facing the irradiation surface, a second outer casing covering the opening surface of the first outer casing, a light source unit disposed in a first internal space formed by being surrounded by the first outer casing and the second outer casing and irradiating light toward the irradiation surface, and a repellent provided along the longitudinal direction of the first outer casing for repelling insects that have invaded or attempt to invade the first internal space, the repellent being provided on the first outer casing so as to fill the gap between the first outer casing and a base on which the light source unit is provided .

According to the present disclosure, a repellent that repels insects that have entered or are attempting to enter the internal space formed by being surrounded by the first outer casing and the second outer casing is provided, so that it is possible to prevent insects from entering the internal space in which the light source unit is provided.

(Lamp 101)
First, each component of the lamp 101 will be described with reference to Figures 1 to 4. The first outer shell 1 is made of a light-transmitting material and is a cover member that covers the periphery of the light source unit 3. Examples of light-transmitting materials include synthetic resins such as polycarbonate or acrylic, or glass. The first outer shell 1 is formed by injection molding, extrusion molding, three-dimensional additive manufacturing, or the like, depending on the material used.

As shown in Figs. 1 and 2, the first outer shell 1 is formed in a long box shape having a translucent irradiation surface and an opening surface facing the irradiation surface. Specifically, as shown in Fig. 3, the first outer shell 1 has a curved cover main part 10 provided on the side of the irradiation surface, cover ends 11 that close both end faces in the longitudinal direction X of the cover main part 10, cover wall parts 12 that rise from both end edges of the cover main part 10 in the lateral direction Y toward the attached part 103, and a pair of L-shaped pedestal attachment parts 13 that protrude from both end edges of the cover wall part 12 toward the inside of the opening.

The cover main part 10 is shown as having a curved cross section as an example, but it may be V-shaped, W-shaped, rectangular, or of other shapes. The cover end part 11 is attached integrally to the cover main part 10 by gluing or the like. As shown in FIG. 3, the cover wall part 12 is formed so that both end edges rising toward the attachment part 103 face the inside of the opening, and L-shaped pedestal attachment parts 13 are provided on both end edges.

As shown in FIG. 3, the base mounting portion 13 is formed along the longitudinal direction X of the first outer shell portion 1, and is provided for mounting the second outer shell portion 2 to the first outer shell portion 1. The base mounting portion 13 is formed in an L-shape with a cover support portion 13a that supports the second outer shell portion 2 and a cover locking portion 13b that locks the second outer shell portion 2.

The cover support portion 13a is formed by extending in the short-side direction Y of the first outer shell portion 1 so as to cover a part of the opening of the first outer shell portion 1. The second outer shell portion 2 is placed on the upper surface of the cover support portion 13a. The cover support portions 13a are formed in parallel on both sides along the longitudinal direction X of the first outer shell portion 1. The light source portion 3 is disposed between the parallel cover support portions 13a and 13a.

The cover locking portion 13b is formed by extending toward the mounting portion 103, and the tip edge of the cover wall portion 12 is connected at the middle portion. The cover locking portion 13b has a hook portion 13c formed at the upper end, and this hook portion 13c is configured to be hooked onto the second outer portion 2.

The second outer part 2 is formed of sheet metal and covers the opening surface of the first outer part 1 as shown in Figs. 3 and 4. The space surrounded by the first outer part 1 and the second outer part 2 becomes the first internal space S1. The second outer part 2 has a flat base part 20 extending along the longitudinal direction X of the first outer part 1, and a base side part 21 rising from both ends of the base part 20 in the lateral direction Y toward the attached part 103. The base part 20 of the second outer part 2 is supported by being placed on the cover support part 13a of the base attachment part 13, and the upper end part of the base side part 21 is hooked and fixed to the hook part 13c of the cover locking part 13b. The means for attaching the second outer part 2 to the first outer part 1 is not limited to the configuration shown in the figure. For example, the second outer shell part 2 may be attached by gluing it to the first outer shell part 1, or the second outer shell part 2 may be attached by sliding it relative to the first outer shell part 1, or some other configuration may be used.

The light source unit 3 is attached to the underside of the base 20, which faces the main cover portion 10. The control unit 4, the wire arrangement tool 40, the wire holder 41, and the mounting tool 5 that engages with the mounting spring 9 are provided on the upper surface of the base 20, which faces the opening side of the first outer shell 1. The base 20 has mounting holes for mounting the control unit 4, the wire arrangement tool 40, the wire holder 41, and the mounting spring 9.

3 and 4, the light source unit 3 has a long substrate 3a and a plurality of light-emitting elements 3b mounted on the surface of the substrate 3a. The substrate 3a is attached to the underside of the base 20 using, for example, an adhesive. The light-emitting elements 3b are, for example, light-emitting diode (Light Emitting Diode) elements. The plurality of light-emitting elements 3b are mounted in a straight line along the longitudinal direction X of the substrate 3a and face the cover main part 10 of the first outer part 1. The light source unit 3 receives power from the control part 4 to cause the light-emitting elements 3b to emit light. The light emitted from the light-emitting elements 3b is irradiated through the cover main part 10 to an illumination space such as an indoor space. The operating heat of the light source unit 3 is dissipated through the second outer part 2 toward a heat dissipation area such as the external space of the lamp 101.

The control unit 4 is configured with a control device provided inside a long protective case, and is attached to the upper surface of the base 20 using a joint member such as a screw. The control unit 4 is arranged at a position where the hanging bolt (not shown) used to attach the device 102 to the mounting portion 103 does not come into contact with the protective case, taking into consideration the position of the hanging bolt (not shown). The control unit has a board and electronic components mounted on the board. The control unit 4 is connected to the light source unit 3 by an electric wire 4a, and is connected to the terminal block 8 via an electric wire 4b. One end of the electric wire 4b is provided with a connector for connecting to the connector of the electric wire 8a connected to the terminal block 8. The control unit 4 has a function as a power source that supplies power supplied from the terminal block 8 to the light source unit 3, and a function to control the lighting power. The operating heat of the control unit 4 is dissipated through the second outer shell 2 toward a heat dissipation area such as the external space of the lamp 101.

The wire arrangement tool 40 is provided to wire the wires 4a and 4b so that they do not come into contact with the hanging bolt (not shown). The wire holder 41 is provided to prevent damage to the power supply part at one end of the wire 4a and to ensure an insulation distance between the power supply part and the base part 20.

As shown in FIG. 4, the mounting fixture 5 is provided to engage with the mounting spring 9 provided on the fixture body 7 to mount the lamp 101 to the fixture 102. The mounting fixtures 5 are provided at positions corresponding to the mounting springs 9, at both ends of the base 20 in the longitudinal direction X. The mounting fixtures 5 are provided at positions and in number as appropriate according to the shape and size of the lighting device 100. Although not shown in the figures, the mounting fixture 5 may be provided on the fixture 102 and the mounting springs 9 on the lamp 101.

As shown in Figures 3 and 4, the repellent 6 is disposed at a location facing the first internal space S1 formed by the first outer shell 1 and the second outer shell 2, and serves to repel insects that have entered or are attempting to enter the first internal space S1. The repellent 6 may be a liquid, a gel or paste-like semi-liquid, a solid, or a gas. The repellent 6 may also be of either a transdermal or oral type.

In the illustrated example, the repellent 6 is provided in a recess formed by the upper end of the cover wall portion 12 and the lower end of the base mounting portion 13. The repellent 6 may be provided continuously along the longitudinal direction X of the first outer shell portion 1 as illustrated, or may be provided in a plurality of dispersed locations at intervals, although this is not illustrated. The repellent 6 may be provided directly, for example, by coating, spraying, or pasting. Alternatively, the repellent 6 may be provided by impregnating a sponge-like porous material or fibrous material with a component that repels insects, or by coating or spraying the repellent component on the surface of a sheet-like member.

Here, insects include, for example, flying insects and wandering insects. Flying insects include, for example, flies, midges, mosquitoes, leafhoppers, planthoppers, whiteflies, bees, cockroaches, etc. Wandering insects include, for example, ants, termites, rove beetles, aphids, silverfish, fleas, lice, mites, centipedes, spiders, etc. Note that these insects are only examples.

If the repellent 6 becomes ineffective after long-term use, the first outer shell 1 is removed from the device 102 and maintenance is performed, such as filling with the repellent 6 or re-installing the repellent 6.

(Apparatus 102)
As shown in Figs. 1 and 2, the fixture main body 7 has a main body 7a extending along the longitudinal direction X and end plate portions 7b attached to both ends of the main body 7a. The main body 7a is formed by bending a metal plate. Specifically, as shown in Fig. 3, the main body 7a is formed by bending so that the cross-sectional shape in the lateral direction Y is concave, and has a recess 70 extending along the longitudinal direction X. The main body 7a is formed by bending obliquely upward from the opening edge of the recess 70 in the lateral direction Y toward the mounting portion 103, and has a slope portion 71 extending along the longitudinal direction X. The slope portion 71 is provided to reflect a part of the light irradiated from the lamp 101 and distribute the light to the side. The main body 7a may be formed using a material other than metal, for example, a resin material.

The recess 70 has a flat top surface 72 extending in the longitudinal direction X, and side surfaces 73 bent from both ends of the top surface 72 in the lateral direction Y toward the lamp 101. The edges of the side surfaces 73 form opening edges that form a rectangular opening.

The top surface portion 72 is formed with a plurality of mounting holes (not shown) through which joining members such as hanging bolts or screws pass in order to attach the fixture 102 to the mounting portion 103. The fixture 102 is attached to the mounting portion 103 by joining the top surface portion 72 to the mounting portion 103 with joining members such as hanging bolts or screws. The top surface portion 72 is also formed with wire passing holes through which external electric wires pass into the interior of the lighting device 100. The external electric wires are connected to the terminal block 8 inside the lighting device 100. The external electric wires include an external power supply line for receiving a supply of electric power. The external electric wires may also include a control line for communicating with the outside of the lighting device 100.

The end plate portion 7b is attached to both ends of the main body portion 7a in the longitudinal direction X so as to close both end faces of the main body portion 7a in the longitudinal direction X. Note that the end plate portion 7b may be provided with a knockout 7c that is opened to pass the power cable through when multiple lighting devices 100 are connected and installed in the longitudinal direction X. In addition, the lower end of the end plate portion 7b is formed with a lower surface portion that is bent toward the center of the main body portion 7a in the longitudinal direction X.

The portion of the fixture 102 surrounded by the recess 70 of the fixture body 7 and the end plate 7b is the lamp mounting portion 7d. The lamp 101 is removably mounted to the lamp mounting portion 7d. When the lamp 101 is mounted to the lamp mounting portion 7d, a portion of the lamp 101 is received through the opening. The interior of the lamp mounting portion 7d when the lamp 101 is mounted to the lamp mounting portion 7d is the second internal space S2.

As shown in FIG. 2, a terminal block 8 and a mounting spring 9 are provided inside the lamp mounting portion 7d. The terminal block 8 is fixed to the top surface 72 of the fixture body 7. The terminal block 8 is connected to fixed wiring (not shown) provided in a building or the like, and is provided to receive power from a commercial power source and to relay control communications. The terminal block 8 is connected to the control portion 4 via an electric wire 8a having a connector at one end.

The mounting spring 9 is provided to mount the lighting device 101 to the fixture 102. As shown in FIG. 2, the mounting spring 9 is made of an elastic material such as stainless steel, and is a leaf spring formed by bending a strip-shaped plate material. The base end of the mounting spring 9 is attached to the top surface portion 72 and protrudes toward the opening side of the lighting device mounting portion 7d. In the illustrated example, the mounting spring 9 is provided at each end of the top surface portion 72 in the longitudinal direction X. Note that the number of mounting springs 9 is not limited to the two shown. For example, if the length of the longitudinal direction X of the lighting device 100 is short, the mounting spring 9 may be provided at one end in the longitudinal direction X and fixed to the other end in the longitudinal direction X by a hook or the like. Also, if the length of the longitudinal direction X of the lighting device 100 is long, the mounting springs 9 may be provided at both ends and the center in the longitudinal direction X. In short, the mounting springs 9 are provided at positions and in number as appropriate according to the shape and size of the lighting device 100.

Here, we will explain the main routes 1 to 3 by which insects invade the first internal space S1 and the second internal space S2. First, we will explain route 1. As shown in Figure 3, an insect in the external space, which is the lighting space, invades the second internal space S2 through a small gap between the upper end of the cover wall portion 12 of the lighting fixture 101 and the lower end of the side portion 73 of the device 102. An insect that invades the second internal space S2 enters the small gap between the upper end of the cover engagement portion 13b and the upper end of the base side portion 21, and then invades the first internal space S1 beyond through the small gap between the cover support portion 13a and the base portion 20.

Next, route 2 will be described. As shown in FIG. 3, an insect in the external space, which is the lighting space, enters the second internal space S2 through a small gap between the upper end of the cover wall portion 12 of the lighting fixture 101 and the lower end of the side portion 73 of the device 102. The insect that entered the second internal space S2 then enters the small gap between the cover support portion 13a and the base portion 20 through the mounting hole formed in the base portion 20, and enters the first internal space S1 beyond.

Next, we will explain route 3. As shown in Figures 1 and 2, insects in the external space, which is the lighting space, enter the second internal space S2 through a small gap between the cover end 11 of the lighting fixture 101 and the end plate portion 7b of the device 102. Then, insects that have entered the second internal space S2 enter the first internal space S1 beyond through small gaps between the cover end 11 and both end faces of the base portion 20 in the longitudinal direction X.

Here, the first internal space S1 is a space into which you do not want insects to enter. The second internal space S2 is a space that can be a route for insects to enter the first internal space S1. If insects enter the first internal space S1 of the lighting device 100 and accumulate in the cover main part 10, etc., the insects will be visible from the outside, significantly degrading the appearance. In addition, insects that accumulate in the first outer shell part 1 block the light that passes through the first outer shell part 1, which may reduce the transmittance. Furthermore, if insects attach to the light source part 3, etc., this may cause malfunctions such as deterioration of electronic components and short circuits, which may compromise safety.

The lighting fixture 101 according to the first embodiment includes a box-shaped first outer part 1 having a translucent irradiation surface and an opening surface facing the irradiation surface, a second outer part 2 covering the opening surface of the first outer part 1, a light source part 3 arranged in a first internal space S1 formed by being surrounded by the first outer part 1 and the second outer part 2 and irradiating light toward the irradiation surface, and a repellent 6 for repelling insects that have entered or are attempting to enter the first internal space S1. Specifically, the repellent 6 is arranged in a location facing the first internal space S1.

In other words, the lighting device 100 according to the first embodiment is provided with a repellent 6 that repels insects that have entered or are attempting to enter the first internal space S1 that is formed by being surrounded by the first outer casing 1 and the second outer casing 2, so that the insects tend to remain in an area in front of the first internal space S1. Therefore, the lighting device 100 can prevent insects from entering the first internal space S1 in which the light source unit 3 is provided. Even if an insect does enter the first internal space S1, the insect can be moved to the outside of the first internal space S1.

Figure 5 is a vertical cross-sectional view showing the main parts of a modified example of the lighting device according to the first embodiment. The lighting device 100A shown in Figure 5 has a configuration in which a repellent 6 is provided on the underside of the base 20 on the side of the cover main part 10. The repellent 6 is arranged along the side surface along the longitudinal direction X of the substrate 3a, and is provided so as to block the small gap between the inner end of the cover support part 13a and the underside of the base 20 placed on the upper surface of the cover support part 13a. In the lighting device 100A, the effect of the repellent 6 extends to the gap between the upper surface of the cover support part 13a and the underside of the base 20, so that insects tend to stay in front of the first internal space S1, and the intrusion of these insects into the first internal space S1 can be effectively suppressed.

The repellent 6 may be provided continuously along the longitudinal direction X of the first outer shell 1, or may be provided in a number of locations at intervals. The lighting device 100A completely seals the gap between the cover support 13a and the base 20 with the repellent 6, physically blocking the path of intrusion, and thus reliably prevents insects from invading the first internal space S1.

The repellent 6 is not limited to being provided on the underside of the base 20 facing the cover main part 10, but may be provided across the cover support part 13a, base 20, and substrate 3a, for example. In this case, the repellent 6 is provided within a range that does not impair the optical properties such as light distribution and the design. The repellent 6 does not need to be provided in a location that blocks the gap between the cover support part 13a and base 20, but may be provided in the vicinity of the gap.

Embodiment 2.
Next, a lighting device 200 according to the second embodiment will be described with reference to Fig. 6. Fig. 6 is a vertical cross-sectional view showing a main part of the lighting device according to the second embodiment. Note that the same components as those in the lighting device described in the first embodiment are given the same reference numerals, and the description thereof will be omitted as appropriate.

As shown in FIG. 6, the lighting device 200 according to the second embodiment is characterized in that the repellent 6 is disposed in a location that does not face the first internal space S1 formed by the first outer portion 1 and the second outer portion 2. Specifically, the repellent 6 is disposed between the upper surface of the cover support portion 13a and the lower surface of the base portion 20. In the lighting device 200 according to the second embodiment, the effect of the repellent 6 extends to the gap between the cover support portion 13a and the base portion 20, and insects can be stopped just before the first internal space S1, so that the insects can be effectively prevented from entering the first internal space S1.

In addition, in the lighting device 200 according to the second embodiment, the repellent 6 is provided in the small gap formed between the upper surface of the cover support portion 13a and the lower surface of the base portion 20, and it is sufficient to fill only the gap with the components of the repellent 6, so that the effect of the repellent 6 is maintained for a long period of time. Therefore, the lighting device 200 is economical because it reduces the burden of maintenance such as refilling the repellent 6 or re-installing it.

The repellent 6 can be made of an elastically deformable porous or fibrous material impregnated with a component that repels insects, so that it can be attached closely to the upper surface of the cover support part 13a and the lower surface of the base part 20. Furthermore, the repellent 6 can be provided continuously along the longitudinal direction X of the first outer shell part 1, or can be provided dispersedly at multiple locations with intervals. The lighting device 200 can completely block the gap between the cover support part 13a and the base part 20 with the repellent 6, physically blocking the entry route, and reliably suppresses insects from entering the first internal space S1.

In addition, in the lighting device 200 according to the second embodiment, the repellent 6 is disposed only between the upper surface of the cover support portion 13a and the lower surface of the base portion 20. However, as shown in the first embodiment, the repellent 6 may be disposed at a location facing the first internal space S1 formed by the first outer portion 1 and the second outer portion 2.

Embodiment 3.
Next, a lighting device (300, 300A, 300B, 300C) according to the third embodiment will be described with reference to Figs. 7 to 10. Fig. 7 is a vertical cross-sectional view showing a main part of the lighting device according to the third embodiment. Note that the same components as those in the lighting devices described in the first and second embodiments are given the same reference numerals, and the description thereof will be omitted as appropriate.

The lighting device 300 according to the third embodiment is characterized in that, as shown in FIG. 7, the repellent 6 is disposed at a location that does not face the first internal space S1 formed by the first outer shell 1 and the second outer shell 2. Specifically, the repellent 6 is disposed on both sides of the control unit 4 disposed on the upper surface of the base 20 at approximately the center of the base 20, and disposed at a location that faces the second internal space S2. In the illustrated example, the repellent 6 is disposed continuously along the longitudinal direction X of the first outer shell 1. The repellent 6 may be disposed at multiple locations at intervals along the longitudinal direction X of the first outer shell 1. The repellent 6 may be disposed on the upper surface of the base 20, and is not limited to the location illustrated.

In the lighting device 300 according to the third embodiment, the repellent component of the repellent 6 fills the second internal space S2, preventing insects from entering the second internal space S2 through small gaps between the lamp 101 and the device 102, and through the mounting holes and wire holes formed in the top surface 72, and thus preventing insects from entering the first internal space S1.

In addition, if the repellent 6 becomes ineffective due to long-term use of the lighting device 300, the lamp 101 is removed from the device 102 and maintenance such as refilling the repellent 6 or re-installing the repellent 6 can be performed. At this time, it is only necessary to remove the lamp 101 from the device 102, and there is no need to remove the second outer casing 2 from the first outer casing 1, which provides excellent workability.

Next, FIG. 8 is a vertical cross-sectional view showing the main parts of the lighting device according to the third embodiment. The lighting device 300A shown in FIG. 8 is also characterized by a configuration in which the repellent 6 is disposed in a location that does not face the first internal space S1 formed by the first outer casing 1 and the second outer casing 2. Specifically, the repellent 6 is provided on the top surface 72 that forms the recess 70 of the device body 7, and is disposed in a location that faces the second internal space S2. In the illustrated example, the repellent 6 is provided on both sides of the control unit 4 disposed approximately in the center of the base 20, and is provided continuously along the longitudinal direction X of the first outer casing 1. The repellent 6 may be provided in a plurality of locations at intervals along the longitudinal direction X of the first outer casing 1. The repellent 6 may be disposed on the top surface 72, and is not limited to the locations shown in the figure.

In the lighting device 300A, the repellent component of the repellent 6 fills the second internal space S2, preventing insects from entering the second internal space S2 through small gaps between the lamp 101 and the device 102, and through the mounting holes and wire holes formed in the top surface 72, and thus preventing insects from entering the first internal space S1.

In addition, if the repellent 6 becomes ineffective due to long-term use of the lighting device 300A, maintenance can be performed by removing the lamp 101 from the device 102 and refilling the repellent 6 or re-installing the repellent 6. At this time, it is only necessary to remove the lamp 101 from the device 102, and there is no need to remove the second outer casing 2 from the first outer casing 1, which provides excellent workability.

Next, FIG. 9 is a vertical cross-sectional view showing the main parts of the lighting device according to the third embodiment. The lighting device 300B shown in FIG. 9 is also characterized by a configuration in which the repellent 6 is disposed in a location that does not face the first internal space S1 formed by the first outer casing 1 and the second outer casing 2. Specifically, the repellent 6 is disposed on each of the left and right side surfaces 73 that form the recess 70 of the device body 7, and is disposed in a location that faces the second internal space S2. In the illustrated example, the repellent 6 is disposed near the opening edge of the recess 70 and is disposed continuously along the longitudinal direction X of the first outer casing 1. The repellent 6 may be disposed in a plurality of locations at intervals along the longitudinal direction X of the first outer casing 1. The repellent 6 may be disposed on the side surfaces 73, and is not limited to the locations shown in the figure.

In the lighting device 300B, the repellent component of the repellent 6 fills the second internal space S2, preventing insects from entering the second internal space S2 through small gaps between the lamp 101 and the device 102, and through the mounting holes and wire holes formed in the top surface 72, and thus preventing insects from entering the first internal space S1. In particular, in the lighting device 300B, the repellent 6 is disposed near the opening edge of the recess 70, effectively preventing insects from entering the second internal space S2.

In addition, if the repellent 6 becomes ineffective due to long-term use of the lighting device 300B, maintenance can be performed by removing the lamp 101 from the device 102 and refilling the repellent 6 or re-installing the repellent 6. At this time, it is only necessary to remove the lamp 101 from the device 102, and there is no need to remove the second outer casing 2 from the first outer casing 1, which provides excellent workability.

Next, FIG. 10 is a vertical cross-sectional view showing the main parts of the lighting device according to the third modified example of the third embodiment. The lighting device 300C shown in FIG. 10 is also characterized in that the repellent 6 is disposed in a location that does not face the first internal space S1 formed by the first outer shell 1 and the second outer shell 2.

In the lighting device 300C, the repellent component of the repellent 6 fills the second internal space S2, preventing insects from entering the second internal space S2 through small gaps between the lamp 101 and the device 102, and through the mounting holes and wire holes formed in the top surface 72, and thus preventing insects from entering the first internal space S1. In particular, the lighting device 300C can effectively prevent insects from entering the inside of the protective cover of the control unit 4, preventing insects from causing malfunctions of the control unit and ensuring stable operation of the control unit 4 over the long term.

In addition, if the repellent 6 becomes ineffective due to long-term use of the lighting device 300C, maintenance can be performed by removing the lamp 101 from the device 102 and refilling the repellent 6 or re-installing the repellent 6. At this time, it is only necessary to remove the lamp 101 from the device 102, and there is no need to remove the second outer casing 2 from the first outer casing 1, which provides excellent workability.

The lighting device (300, 300A, 300B, 300C) according to the third embodiment has a configuration in which the repellent 6 is disposed only at the portion facing the second internal space S2, but as shown in the first embodiment, a configuration in which the repellent 6 is disposed at the portion facing the first internal space S1 formed by the first outer portion 1 and the second outer portion 2 may also be used. The lighting device (300, 300A, 300B, 300C) according to the third embodiment may also be used in a configuration in which the repellent 6 is disposed between the upper surface of the cover support portion 13a and the lower surface of the base portion 20, as shown in the second embodiment.

Embodiment 4.
Next, a lighting device 400 according to a fourth embodiment will be described with reference to Fig. 11. Fig. 11 is a vertical cross-sectional view showing a main part of a lighting device according to the fourth embodiment. Note that the same components as those in the lighting devices described in the first to third embodiments are given the same reference numerals, and the description thereof will be omitted as appropriate.

In the lighting device 400 according to the fourth embodiment, the repellent 6 is composed of a first repellent 60 installed at a location facing the first internal space S1 formed by the first outer shell 1 and the second outer shell 2, and a second repellent 61 installed at a location not facing the first internal space S1. Specifically, the first repellent 60 is provided in a recess formed by the upper end of the cover wall portion 12 and the lower end of the base mounting portion 13. The second repellent 61 is provided on the upper surface of the base portion 20 on both sides of the control unit 4, and is arranged at a location facing the second internal space S2. The first repellent 60 may be provided continuously along the longitudinal direction X of the first outer shell 1, or may be provided in a plurality of locations at intervals. The second repellent 61 may be provided continuously along the longitudinal direction X of the protective cover, or may be provided in a plurality of locations at intervals.

In the lighting device 400 shown in FIG. 11, a configuration in which the first repellent 60 and the second repellent 61 are provided is shown, but the second repellent 61 may be omitted and only the first repellent 60 may be provided, or the first repellent 60 may be omitted and only the second repellent 61 may be provided. In addition, the first repellent 60 and the second repellent 61 are not limited to being provided at the locations shown in the figure, and may be provided at the locations described in the first to third embodiments.

In the lighting device 400 according to the fourth embodiment, through holes 73a are formed in the left and right side portions 73 forming the recess 70 to allow insects that have entered the second internal space S2 to escape to the third internal space S3 surrounded by the fixture 102 and the mounting portion 103. The number of through holes 73a may be one or more. The size of the through holes 73a is appropriately changed depending on the size and shape of the lighting device 400 or the installation location. If a hole for heat dissipation or wiring is formed in the side portion 73, the hole may be used as a through hole to allow insects to escape to the third internal space S3.

In the illustrated example, the third internal space S3 is a space surrounded by the inclined surface portion 71, side surface portion 73, and end plate portion 7b of the device 102, and the mounting portion 103. The third internal space S3 is formed on both the left and right sides of the recess 70. The third internal space S3 is connected to the second internal space S2 through the through hole 73a.

In the third internal space S3, an attractant 74 for attracting insects is provided near the through hole 73a. In the illustrated example, the attractant 74 is provided by utilizing a depression formed by the lower part of the inclined surface portion 71 and the lower part of the side surface portion 73. The attractant 74 contains a component that insects like, and may be any of liquid, gel or paste-like semi-liquid, solid, and gas. The attractant 74 may be provided continuously along the longitudinal direction X of the device 102, or may be provided in a plurality of locations at intervals. The attractant 74 may be either a transdermal or oral type. The attractant 74 may also contain a component that kills insects. The attractant 74 may be directly provided by, for example, coating, spraying, or pasting, or may be provided by impregnating a sponge-like porous material or fibrous material with a component that attracts insects, or by coating or spraying the attractant component on the surface of a sheet-like member.

As shown in the figure, the location where the attractant 74 is provided is preferably near the through hole 73a facing the third internal space S3, but it may be provided in another location within the third internal space S3 or in a location facing the second internal space S2. In short, the attractant 74 may be provided anywhere as long as it can attract insects from the second internal space S2 to the third internal space S3.

In addition, if the attractant 74 no longer exerts its effect due to long-term use of the lighting device 400, maintenance can be performed by removing the fixture 102 from the mounting portion 103 and filling it with the attractant 74 or re-installing the attractant 74.

Here, we will explain the main routes 1 to 3 that attract insects into the third internal space S3. First, we will explain route 1. Insects in the external space, which is the lighting space, enter the second internal space S2 through a small gap between the upper end of the cover wall portion 12 of the lighting fixture 101 and the lower end of the side portion 73 of the device 102. The insects are then attracted by the attractant 74 and enter the third internal space S3 through the through hole 73a of the side portion 73.

Next, route 2 will be described. When the mounting portion 103 is a ceiling, insects in the space above the ceiling enter the second internal space S2 through holes for mounting or electrical wires formed in the mounting portion 103 and the top surface portion 72 of the device 102. The insects are then attracted by the attractant 74 and enter the third internal space S3 through the through hole 73a in the side surface portion 73. Next, route 3 will be described. Insects in the space above the ceiling enter directly into the third internal space S3 through holes for mounting or electrical wires formed in the mounting portion 103.

As described above, the lighting device 400 according to the fourth embodiment has a through hole 73a formed in the lamp mounting portion 7d that communicates with the outside. An attractant 74 is provided near the through hole 73a to attract insects that have invaded the second internal space S2 to the outside through the through hole 73a. Therefore, the lighting device 400 can attract insects that have invaded the second internal space S2 to the outside through the through hole 73a, thereby preventing insects from invading the first internal space S1 in which the light source unit 3 is provided.

Embodiment 5.
Next, a lighting device 500 according to a fifth embodiment will be described with reference to Figs. 12 and 13. Fig. 12 is a vertical cross-sectional view showing a main part of the lighting device according to the fifth embodiment. Note that the same components as those in the lighting devices described in the first to fourth embodiments are given the same reference numerals, and the description thereof will be omitted as appropriate.

As shown in FIG. 12, the lighting device 500 according to the fifth embodiment is characterized by a configuration in which the lighting device 500 can be freely inserted and removed from the second internal space S2 to the third internal space S3 through the through hole 73a and includes a capture member 75 provided near the through hole 73a. The other configurations are basically the same as those of the fourth embodiment.

The capture member 75 has a groove 75a that is installed in a recess formed by the lower part of the sloped surface 71 and the lower part of the side surface 73, and a hook 75b that is provided at one end edge of the groove 75a and hooks onto the opening edge of the through hole 73a, and is detachably attached to the side surface 73 of the device 102. An attractant 74 is provided in the groove 75a. The capture member 75 is configured to be large enough to be inserted and removed from the second internal space S2 through the through hole 73a into the third internal space S3. The capture member 75 may be configured as a single unit having a predetermined length along the longitudinal direction X of the device 102, or may be configured as multiple members arranged at predetermined intervals along the longitudinal direction X of the device 102.

The capturing member 75 hooks the latch portion 75b onto the opening edge of the through hole 73a, so that the capturing member 75 cannot be easily removed when the lamp 101 is attached to the device 102. In other words, the capturing member 75 cannot be easily removed even if the lighting device 500 is subjected to vibration or impact. Although not shown in the figures, the capturing member 75 may be configured to be removable from the device 102 when the lamp 101 is attached to the device 102.

Figure 13 is an explanatory diagram showing the procedure for removing the capture member of the lighting device according to embodiment 5. Figure 13 (A) shows the state in which the capture member 75 is installed in the third internal space S3 by hooking the hook portion 75b onto the opening edge of the through hole 73a of the side portion 73. Figure 13 (B) shows the state in which the capture member 75 has been lifted up to a position where it can be removed from the through hole 73a. Figure 13 (C) shows the state in which the groove portion 75a has been moved from the third internal space S3 to the second internal space S2.

When the attractant 74 is no longer effective due to long-term use of the lighting device 500, the trapping member 75 is removed from the opening edge of the through-hole 73a of the side portion 73 as shown in Figs. 13(A) to (C), and maintenance such as filling with the attractant 74 or re-installing the attractant 74 is performed. In addition, dead insects that were attracted by the attractant 74 may be captured in the groove portion 75a of the trapping member 75. In this case, by removing the trapping member 75, the insects can be removed while performing maintenance on the attractant 74, so the device 102 can be kept clean.

Although the lighting device has been described above based on the embodiment, the lighting device is not limited to the configuration of the above-mentioned embodiment. The configuration of the lighting device described above is one example, and may include other components. Also, while an example has been shown in which the first outer casing 1 and the second outer casing 2 are configured as separate members, they may be configured to be integrally formed as a cylindrical member, for example. In short, the lighting device includes the range of design modifications and application variations that are normally made by a person skilled in the art, within the scope of the technical concept.
