Description

  The present invention relates to a lighting apparatus that suppresses insects from entering the apparatus.

  In a lighting fixture in which a glove can be attached to and detached from the fixture body, a gap is usually generated between the fixture body and the glove, and such a gap is a path when an insect attracted by the illumination light enters the fixture. It becomes. Insects that enter the interior of the instrument through such a path not only move around in the glove or become dead in the glove, detract from the aesthetics of the luminaire, but also come into contact with the high voltage part of the luminaire. There is a risk of overheating, malfunction or failure of the instrument. Therefore, in order to suppress the invasion of insects into the inside of such an instrument, an illumination in which the gap between the instrument body and the glove is filled with an elastic material and the instrument body and the glove are completely brought into close contact via the elastic body. An instrument is known (see, for example, Patent Document 1).

International Publication No. 2012/008280

  However, in the lighting fixture as described above, since an elastic body is provided in the gap between the fixture body and the globe, a large frictional force is generated between the fixture body and the globe when the globe is attached to the fixture body. This occurs and mounting operability is poor. In addition, since the fixture body and the globe are completely in contact with each other through the elastic body, when the fixture body and the globe are thermally expanded due to the heat accompanying lighting of the lighting fixture, or when the fixture body and the globe are turned off, When heat shrinks, abnormal noise may be generated due to the stress caused by the difference in thermal expansion coefficient between the instrument body and the globe and the difference in thermal shrinkage.

  The present invention solves the above-described problem, and suppresses the invasion of insects into the inside of the instrument, improves the operability of attaching the glove to the instrument body, and prevents the generation of abnormal noise during lighting or extinguishing. It is an object of the present invention to provide a lighting device that can be used.

  The lighting fixture of the present invention comprises a plate-like fixture body, a light source part attached to one surface of the fixture body, and a glove attached to the fixture body so as to cover the light source part, The globe includes a flange provided at a peripheral end thereof and extending in parallel with the instrument body, and an engagement part provided at a part of the flange and used to engage with the instrument body, The instrument body has a holding part that is used to hold the globe by engaging with the engaging part, and a relative surface of the flange that faces the instrument body and a relative face of the instrument body that faces the flange. A repellent holding layer containing an insect repellent is provided in at least one of the regions, and a gap is formed between the repellent holding layer and the flange or the instrument body or between the repellent holding layers. Yo In, characterized in that said engaging portion and the holding portion are engaged with each other.

  The light source unit includes an LED as a light source, and the LED emits light more than the flange when viewed from a direction orthogonal to the optical axis in a state where the optical axis is orthogonal to the instrument body. It is preferable to arrange at the same height as the direction side or the flange.

  The size of the gap is preferably 2 mm or less.

  The repellent holding layer is preferably disposed on the outer side of the instrument in the relative surface of the flange or the relative region of the instrument body.

  In the case where the repellent holding layer is provided in the instrument body, it is preferable that the repellent retention layer extends to a region of the relative region on the outer side of the instrument.

  It is preferable that the width of the repellent holding layer in the relative surface of the flange or the relative region of the instrument body is configured to be 2 mm or more in the direction from the outside of the instrument toward the inside of the instrument.

The insect repellent is preferably composed of a nonvolatile pyrethroid compound as a main component, and is preferably added at a concentration of 0.01 g / m ² or more to the repellent retention layer.

  The instrument body 2 is formed in a donut plate shape having a circular hole 21 at the center thereof, and has an adapter 22 that engages with the hole 21. The adapter 22 is attached to a hook ceiling C <b> 1 (see FIG. 1) provided on the ceiling C, whereby the instrument body 2 is fixed to the ceiling C. The adapter 22 has a circuit unit (not shown) that controls lighting of the light source unit 3. The circuit unit is connected to a commercial power source through the hook ceiling C1 when the adapter 22 is attached to the hook ceiling C1, and controls power supply from the commercial power source to the light source unit 3. In addition, the instrument body 2 has a peripheral frame 23 that is bent toward the globe 4 at a peripheral end portion thereof, and a holding portion 24 that is erected from the mounting surface 2A in the vicinity of the peripheral frame 23 and used to hold the globe 4. And having. The holding part 24 has a recessed part 24 a that engages with an engaging part 42 (see below) of the globe 4.

  The light source unit 3 includes a wiring board 31 attached to the mounting surface 2A of the instrument body 2, a plurality of LEDs 32 mounted on a surface opposite to the surface attached to the mounting surface 2A of the wiring board 31, and the LEDs 32. And a light distribution control unit 33 that controls the light distribution of the emitted light. The wiring board 31 is formed in a donut plate shape having a circular hole 31a larger than the hole 21 of the instrument body 2 at the center thereof, and the center of the hole 31a coincides with the center O of the hole 21 (see FIG. 2). And attached to the instrument body 2. The plurality of LEDs 32 serving as the light sources are arranged at equal intervals on two concentric circles centered on the center O in a state where the respective optical axes Ax are orthogonal to the instrument body 2. When the globe 4 is attached to the instrument body 2, the LED 32 is on the light emission direction side (lower side in FIG. 1) or the flange 41 than the flange 41 (see below) of the globe 4 when viewed from the direction orthogonal to the optical axis Ax. In the illustrated example, it is arranged on the light emission direction side with respect to the flange 41. The LED 32 includes, for example, a blue LED chip that emits blue light, a sealing material that seals the blue LED chip, and a phosphor that is dispersed in the sealing material and converts blue light into yellow light. Then, white light is emitted by mixing blue light and yellow light with each other. The light distribution control unit 33 includes a plurality of lenses 33a that cover the respective LEDs 32, and a connection unit 33b that connects the lenses 33a to each other, and is configured as a single member. The plurality of lenses 33a are each formed in a substantially hemispherical shape, and are disposed so as to house the LEDs 32 therein. The lens 33a refracts and emits the light emitted from the LED 32 in the direction of the optical axis Ax.

  The globe 4 is formed in a substantially spherical shape, and is attached to the instrument body 2 so as to accommodate the light source unit 3 therein. The globe 4 has a flange 41 extending from the peripheral end thereof toward the outside of the instrument in parallel with the instrument body 2 and an engaging portion 42 used for engaging with the instrument body 2 (see FIG. 1). . The engaging portion 42 is constituted by a claw formed so as to extend from a part of the base portion of the flange 41 toward the inside of the instrument, and engages with the recess 24 a of the instrument body 2. Thereby, the globe 4 is attached to the instrument main body 2. The globe 4 is made of, for example, a milky white translucent material, and diffuses light from the light source unit 3 and emits the light to the outside. This translucent material is made of, for example, a resin such as acrylic resin, polycarbonate resin, polystyrene resin, or polyethylene resin, or glass.

  As shown in FIG. 3, a repellent holding layer 5 for preventing insects from entering the inside of the device is provided in the relative region R facing the flange 41 of the globe 4 in the device body 2. At this time, the holding part 24 (not shown) of the instrument body 2 and the engaging part 42 (not shown) of the globe 4 are mutually connected so that a gap G is formed between the repellent holding layer 5 and the flange 41. Engage. In the illustrated example, the repellent holding layer 5 extends to a region outside the instrument in the relative region R. The size of the gap G is 2 mm or less, preferably 0.05 to 2 mm, more preferably 0.1 to 2 mm. The width of the repellent holding layer 5 in the relative region R is configured to be 2 mm or more in the direction from the outside of the device to the inside of the device. The repellent retention layer 5 has a thickness of 0.1 mm to 10 mm. In addition, the insects mentioned here refer to flying insects, dwarf insects and the like having a body length of about 1 mm to 20 mm that can enter the gap G. Flying insects include, for example, flies, chironomids, mosquitoes, leafhoppers, planthoppers, whiteflies, bees, and cockroaches. Dwarf insects include, for example, ants, termites, beetles, aphids, and worms. Examples of other insects include fleas, lices, mites, centipedes, and moths.

  The repellent holding layer 5 has a base material 51 and an insect repellent 52 contained in the base material 51. The base material 51 is comprised with an elastic member, a coating material, a film, resin, or glass, for example. In the case where the substrate 51 is made of an elastic member (urethane, polyethylene, rubber, foamable member, etc.), the repellent holding layer 5 is, for example, after the substrate 51 is soaked in a solvent containing the insect repellent 52, It is formed by volatilizing the solvent from the substrate 51 by drying. In addition, when the substrate 51 is made of paint (acrylic resin, fluorine resin, silicon resin, urethane resin, phenol resin, etc.), the repellent holding layer 5 is, for example, a paint and an insect repellent. It is formed by applying a mixture of 52 and 52. Further, when the substrate 51 is made of a film (acrylic resin, polycarbonate resin, polystyrene resin, polyester resin, cellulose resin, vinyl chloride resin, polyamide resin, glass, etc.), a repellent holding layer 5 is formed by sticking a film containing an insect repellent 52, for example. Further, when the substrate 51 is made of resin (acrylic resin, polycarbonate resin, polystyrene resin, polyethylene resin, etc.) or glass, the repellent holding layer 5 is made of insect repellent 52 on these resin or glass. It is formed by kneading.

The insect repellent 52 is mixed with a binder and added at a concentration of 0.01 g / m ² or more with respect to the substrate 51 (repellant holding layer 5). The binder is made of, for example, a resin such as acrylic resin, fluorine resin, silicon resin, urethane resin, or phenol resin, or a porous material such as pumice. By using such a binder, the adhesiveness of the insect repellent 52 to the base material 51 can be improved, and the durability of the insect repellent 52 can be improved and the life of the insect repellent 52 can be extended. The insect repellent 52 is preferably composed of a main component of a pyrethroid compound that has high safety for mammals and is non-volatile and highly durable. Such non-volatile pyrethroid compounds produce insect repellent effects by direct contact with insect tactile sensation and legs, such as pyrethrin, cineline, diathmorine, allethrin, phthalthrin, resmethrin, flamethrin, phenothrin, vermethrin, imibrothrin. , Ciphenothrin, tralomethrin, etofenprox, plaretrin, cyfluthrin, silafluophene, bifenthrin, flumethrin, fulvalinate, deltamethrin, empentrin, methfluthrin, transfluthrin. The insect repellent 52 is not limited to a pyrethroid compound, and may be composed of an organic phosphorus compound, a naturally derived plant essential oil, or the like.

  In the lighting fixture 1 configured as described above, consider a case where an insect tries to enter the inside of the fixture through the gap G. At this time, the size of the gap G is configured to be 2 mm or less, and the repellent holding layer 5 is extended to the region outside the instrument in the relative region R. The repellent holding layer 5 in the relative region R Since the width is 2 mm or more, insects can easily come into contact with the repellent holding layer 5. Insects that have come into contact with the repellent holding layer 5 escape to the outside of the instrument so as to avoid further contact with the repellent holding layer 5. As described above, in the lighting device 1, it is possible to suppress the invasion of insects from the gap G into the device while providing the space G between the device body 2 and the globe 4.

  On the other hand, by providing the gap G, the instrument body 2 and the globe 4 are not in direct contact when the holding part 24 of the instrument body 2 and the engaging part 42 of the globe 4 are engaged with each other. Therefore, a large frictional force does not work between the instrument main body 2 and the globe 4, and the globe 4 can be smoothly attached to the instrument main body 2 with a small force, and the mounting operability is good. In addition, since the gap G is provided, even if the instrument body 2 and the globe 4 are thermally expanded due to the heat accompanying the light emission of the LED 32, or the instrument body 2 and the globe 4 are thermally contracted by turning off the LED 32, The stress caused by the difference in thermal expansion coefficient and the difference in thermal contraction between the instrument body 2 and the globe 4 can be efficiently released. Thereby, generation | occurrence | production of the abnormal noise by the stress distortion in the instrument main body 2 and the globe 4 can be prevented.

  As described above, according to the lighting device 1, since the repellent holding layer 5 is provided with the gap G between the device body 2 and the globe 4, the insects can be prevented from entering the device. The operability of attaching the globe 4 to the instrument body 2 is good, and it is possible to prevent the generation of abnormal noise during lighting or extinguishing.

  Further, since the optical axis Ax of the LED 32 is orthogonal to the instrument main body 2 and the LED 32 is arranged on the light emission direction side or at the same height as the flange 41 with respect to the flange 41 of the globe 4, the light emitted from the LED 32 It is difficult to leak from the gap G to the outside of the instrument (see FIG. 1). Thereby, even if it is a case where a high-intensity light source like LED32 is used, the trigger of the insect by the light which leaked out of the instrument from the clearance gap G can be suppressed. Even if insects are attracted to the lighting device 1 by light leaking outside the device, such insects are unlikely to enter the device because the repellent holding layer 5 is provided. Furthermore, by using the LED 32 including a blue LED chip and a phosphor as a light source, it is possible to reduce ultraviolet radiation from the light source as compared with the case where a fluorescent lamp is used as the light source, thereby suppressing insect incentives due to ultraviolet rays. be able to.

  Next, a first modification of the above embodiment will be described with reference to FIG. The lighting fixture of the present modification is based on the lighting fixture 1 described above, and the repellent holding layer 5 is disposed only on the outer side of the fixture in the relative region R. By doing in this way, insects entering the gap G come into contact with the repellent holding layer 5 at an early stage and it is difficult to stay around the gap G. Therefore, a smaller amount of the repellent holding layer than the lighting fixture 1 5 can also prevent insects from entering the instrument.

  Next, a second modification of the above embodiment will be described with reference to FIGS. The lighting fixture shown in FIG. 5A is obtained by extending the repellent holding layer 5 to the inner peripheral surface of the peripheral frame 23 of the fixture body 2 based on the lighting fixture 1 described above. Moreover, the lighting fixture shown in FIG.5 (b) is what extended the repellent holding layer 5 to the surface facing the globe 4 in the surrounding frame 23 based on the lighting fixture 1 shown in Fig.5 (a). It is. By doing in this way, since the opportunity for an insect to contact the repellent holding layer 5 can be increased, it is possible to more reliably suppress the insect from entering the instrument.

  Next, a third modification of the above embodiment will be described with reference to FIGS. The luminaire shown in FIG. 6A is based on the luminaire 1 described above, and is provided with the repellent holding layer 5 on the relative surface 41a of the flange 41 of the globe 4 facing the fixture body 2. Moreover, the lighting fixture shown in FIG. 6 (b) is based on the lighting fixture shown in FIG. 6 (a), and the repellent holding layer 5 on the side of the fixture main body 2 is replaced with the repellent holding layer 5 that does not contain the insect repellent 52. (That is, only the base material 51). Furthermore, the lighting fixture shown in FIG. 6 (c) is provided with the repellent holding layer 5 on the globe 4 up to the location facing the peripheral frame 23 of the fixture body 2 in the globe 4 based on the lighting fixture shown in FIG. 6 (a). It is extended along the outer side surface. By doing so, the gap G is reduced, so that the chance of insects coming into contact with the repellent holding layer 5 is increased, and insects can be more reliably prevented from entering the device.

  Next, the 4th modification of the said embodiment is demonstrated with reference to Fig.7 (a) (b). The luminaire shown in FIG. 7A is provided with a concavo-convex structure 53 on the surface of the repellent holding layer 5 based on the luminaire 1 described above. The height of the concavo-convex structure 53 is about 1 mm. Moreover, the lighting fixture shown in FIG.7 (b) forms the uneven structure 53 with the fibrous material based on the lighting fixture shown in Fig.7 (a). Such a fibrous substance is composed of, for example, brushed fibers or planted fibers, and includes animal and plant fibers such as cotton, hemp, silk, and chemical fibers such as rayon, nylon, polyester, acrylic, polyvinyl chloride, and glass. It is configured by braiding (French pile), non-woven fabric, flocking, and felt. The insect repellent 52 is added to the fibrous material by, for example, applying the insect repellent 52 to the fibrous material using a brush or a sponge. By providing such a concavo-convex structure 53, the surface area of the repellent holding layer 5 is increased and the chance of insects coming into contact with the repellent holding layer 5 is increased, so that insects can be more reliably prevented from entering the inside of the instrument. be able to.

(Example)
The lighting fixture of the present invention was produced based on a Panasonic ceiling light (model number: HH-LC762A), and the operability of attaching the globe 4 to the fixture body 2 and the ease of insects entering the fixture were evaluated. Insects can easily enter the interior of the fixture by illuminating the lighting fixture 1 in which the light source 3 is turned on in a state in which the electric wire hole and the fixture mounting hole of the lighting fixture are closed so that insects can enter the appliance only from the gap G. Was evaluated outdoors by measuring the number of insects that had invaded the instrument two nights later.

Example 1 corresponds to the luminaire 1 shown in FIG. 3, and the width of the repellent holding layer 5 in the relative region R was 6 mm. Example 2 corresponds to the lighting apparatus shown in FIG. 4, and the width of the repellent holding layer 5 in the relative region R was 3 mm. Example 3 corresponds to the lighting apparatus shown in FIG. In Examples 1 to 3, the repellent holding layer 5 was configured by applying an acrylic paint mixed with the nonvolatile insect repellent 52 to the instrument body 2. Example 4 corresponds to the lighting apparatus shown in FIG. 7 (a), and uses urethane paint having a concavo-convex structure 53 as a base 51, and an acrylic paint in which an insect repellent 52 is mixed on the surface of this urethane. The repellent holding layer 5 was formed by coating. Example 5 corresponds to the lighting apparatus shown in FIG. 7B, and nylon was used as the base material 51, and the repellent holding layer 5 was configured by impregnating the insect repellent 52 into this nylon. In all of Examples 1 to 5, the insect repellent 52 was added to the substrate 51 at a concentration of 10 g / m ² .

  On the other hand, as shown in FIG. 8A, in Conventional Example 1, the repellent holding layer 5 in Example 1 is replaced with the repellent holding layer 5 that does not include the insect repellent 52 (that is, only the base material 51). It was assumed. Further, as shown in FIG. 8B, Conventional Example 2 is based on Conventional Example 1 in which gap G is completely closed with base material 51.

Table 1 below shows the mounting operability of the glove 4 to the instrument body 2 and the number of insects invading into the instrument in Examples 1 to 5 and Conventional Examples 1 and 2 described above. In Example 1, the mounting operability was good, and the number of insects that entered the inside of the instrument was “1”. Here, the number of insects that have entered the instrument is expressed as a relative ratio when the number of insects that have entered the instrument is “10” in Conventional Example 1. In Example 2, the mounting operability was good, but since the width of the repellent holding layer 5 was narrower than that in Example 1, the number of insects that entered the instrument increased to “3”. In Example 3, since the repellent holding layer 5 is extended to the surface facing the globe 4 in the device body 2, the device body 2 and the globe 4 are easily brought into contact with each other, and the mounting operability is slightly deteriorated. However, the number of insects that entered the instrument was “0”. In Examples 4 and 5, the mounting operability was good, and the number of insects that entered the instrument was “0”. On the other hand, in the conventional example 1, although the mounting operability is good, many insects have entered the inside of the instrument. In Conventional Example 2, although the number of insects that entered the instrument was “0”, the mounting operability was very poor.

Table 2 below shows the effect of the concentration of the insect repellent 52 on the number of insects that have entered the device. In Example 5 described above, the insect repellent 52 was added at a concentration of 10 g / m ² with respect to the base material 51, and the number of insects that entered the instrument was “0”. When the concentration of the insect repellent 52 was gradually decreased from this concentration, the number of insects that entered the device increased as the concentration of the insect repellent 52 decreased. However, even at a concentration of 0.01 g / m ² , The number of insects that invade the plant can be significantly reduced.

  In addition, the lighting fixture which concerns on this invention is not limited to the said embodiment and its modification, A various deformation | transformation is possible. For example, the repellent holding layer may be provided only on the relative surface of the flange. In this case, the width of the repellent holding layer is configured to be 2 mm or more in the direction from the outside of the device to the inside of the device. It is preferable. Moreover, the repellent holding layer provided in the instrument body does not necessarily extend to the area outside the instrument in the relative area, and may be provided so as to occupy only the relative area. Further, the light source is not limited to the LED, and may be configured by a fluorescent lamp or an HID lamp. The lighting fixture is not limited to a ceiling light, and may be configured as a floodlight that projects a street lamp or a ground installed in a park, for example. Moreover, the shape of the lighting fixture is not limited to a circular shape in plan view, and may be, for example, a rectangular shape in plan view.
