JP 7-14410 A

  By the way, when attaching an illuminating device to a ceiling, it is often attached to the attachment port previously provided in the deepest part of the recessed part. This is for providing a reflecting plate in the recess to make it brighter than when using a lighting device having the same light amount. However, when a lighting fixture that has a reflector inside the frame and emits light from a light transmitting portion provided in the frame is not necessary, it is not necessary to dispose the reflector in a concave shape. In addition, the exposure of such a concave shape has a problem that the aesthetic appearance is not excellent.

  The present invention has been made in view of such a problem. For example, when a lighting device is attached to a concave portion provided on a ceiling or the like, the lighting device has a sense of unity with the ceiling surface without making the concave portion conspicuous. The main object is to provide an auxiliary device for lighting and a lighting device provided with the auxiliary tool for lighting.

  The present invention adopts the following means in order to achieve at least one of the above objects.

The auxiliary device for lighting device of the present invention comprises:
An auxiliary device for an illuminating device for an illuminating device attached to an attachment port provided in the deepest part of the recess,
A lid member that has a through-hole through which at least a part of the illumination device can pass, and covers the entire recess;
An urging member that is provided on one side of the lid member and urges the lid member in the direction of the attachment port;
It is a thing with.

  In this auxiliary device for lighting device, since at least a part of the lighting device has a through-hole through which the cover member covering the entire recess is urged to the surface side of the recess, the cover member does not make the recess conspicuous. Can be. For example, when the concave portion is provided on the ceiling, the lid portion is urged on the ceiling surface, so that a sense of unity with the ceiling surface is obtained and the appearance is excellent. At this time, since the cover member is provided with a through-hole through which the lighting device can pass, a sense of unity with the ceiling surface can be obtained without impairing the beauty of the lighting device itself.

  In the auxiliary tool for lighting device of the present invention, the one surface side may be the attachment port side of the lid member. In this case, since the biasing member is arranged at the attachment port side, that is, the position inside the recess and not visible from the outside, it is possible to reduce the possibility that the biasing member impairs the beauty. Can do. In other words, it is more aesthetically pleasing than when the urging member is disposed at a position where it can be seen from the outside.

  In the auxiliary tool for lighting device of the present invention, the lid member may be a reflecting surface on which the urging member is provided on the one surface side and the other surface side reflects light emitted from the lighting device. If it carries out like this, the light irradiated from the illuminating device which passed the through-hole will be reflected by the cover member, and light will be irradiated to a floor surface. Therefore, the design can be drawn on the floor surface by the light irradiated from the lighting device. For this reason, a design can be drawn on both a cover member and a floor surface by making the other surface side into a reflective surface, and it is more excellent in aesthetics.

  The auxiliary device for a lighting device according to the present invention includes a detachable member that is connected to the urging member and is attachable to and detachable from the lighting fixture from the direction of the attachment port, and the urging member includes the detachable member as the illuminating device. When attached to the lid, the lid member may be biased toward the attachment port. If it carries out like this, the auxiliary tool for lighting devices can be attached by simple operation of attaching a detachable member to a lighting fixture from an attachment port direction. In other words, it is possible to provide an illuminating device that is excellent in aesthetics with less effort compared to the case where no detachable member is provided.

  In the illumination device auxiliary tool of the present invention, the attachment / detachment member has an attachment / detachment hole having an inner diameter smaller than the outer diameter of the illumination device, and when a part of the illumination device is inserted into the attachment / detachment hole, The diameter is attached to the illuminating device by being caught in the attachment / detachment hole, and the urging member moves in the direction of the attaching port as the illuminating device moves when the illuminating device is attached to the attaching port. When the tip of the recess and the lid member come into contact with each other and the distance between the detachable member and the lid member is increased, the lid member and the detachable member are urged in a direction approaching the lid member. May be biased toward the mounting opening. In this way, when the attachment / detachment hole of the attachment / detachment member is fitted into the lighting device from the direction of the attachment port, the attachment / detachment hole is caught on the upper part of the illumination device. Can be attached. Thereafter, when the lighting device is attached to the attachment port, the illumination device moves in the direction of the attachment port, the tip of the recess comes into contact with the lid member, and the detachable member and the lid member are separated. At this time, since the lid member is urged by the urging member in a direction in which the lid member and the detachable member come closer, the lid member is urged toward the ceiling surface. Thus, the auxiliary tool for lighting device can be attached by a simple operation of attaching the detachable member to the lighting fixture from the direction of the mounting opening. In other words, it is possible to provide an illuminating device that is excellent in aesthetics with less effort compared to the case where no detachable member is provided.

  In the auxiliary tool for lighting device of the present invention, the biasing member may be two or more coil springs. In this case, since the lid member is urged by a plurality of coil springs, the possibility that the lid member is inclined with respect to the ceiling surface is reduced compared to the case where the lid member is urged by one coil spring. can do. In other words, it is possible to reduce the possibility that a gap is generated between the lighting device and the ceiling surface and the aesthetic appearance is impaired. In addition, since the lighting device diffuses light, even a slight scratch greatly detracts from aesthetics, but the possibility that the lighting device and the urging member come into contact with each other to be damaged is also reduced.

  In the auxiliary tool for lighting device according to the present invention, the biasing member may be a conical coil spring whose diameter decreases as the distance from the lid member increases. If it carries out like this, the auxiliary tool for illuminating devices can be attached to an illuminating device by simple operation which covers a conical coil spring from the attachment opening direction of an illuminating device. In other words, it is possible to provide an illumination device that is excellent in aesthetics with less labor.

  In the auxiliary device for lighting device of the present invention, the lid member may be made of metal or resin. If it is made of metal, it has rigidity and is excellent in strength, so that it can be a lid member excellent in durability. Moreover, since it can be set as the cover member which has metallic luster, the illuminating device excellent in aesthetics can be provided. On the other hand, if it is made of resin, the weight can be further reduced as compared with the case where the lid member is made of metal. In other words, it is possible to provide an illumination device that is excellent in aesthetics while reducing labor during installation.

  The illumination device of the present invention includes a light source provided at a position closer to the attachment port than the lid member, and a light guide provided at a position farther from the attachment port than the lid member to diffuse light emitted from the light source. And a lighting device having a light section. In this way, the cords and the like necessary for connection to the light source can be stored in a position that cannot be seen from the outside by the lid member. In other words, it is possible to reduce the possibility that the aesthetics will be damaged by the cords connected to the light source.

  Here, based on the above-described drawings, the correspondence between the constituent elements of the present embodiment and the constituent elements of the present invention will be clarified in describing the embodiment for carrying out the present invention. The lighting device 10 of the present embodiment corresponds to the lighting device of the present invention, the lighting device auxiliary tool 20 corresponds to the lighting device auxiliary tool, the concave portion 100 corresponds to the concave portion, and the mounting port 102 corresponds to the mounting port.

An example of a method of using the lighting device and the lighting device auxiliary tool of the present invention is also described by explaining a method of mounting the lighting device auxiliary tool 20 to the lighting device 10 and a method of mounting the lighting device 10 to the ceiling surface. It is clear.

  Next, with reference to FIG. 1 and FIG. 2, configurations of the lighting device 10 and the lighting device auxiliary tool 20 which are examples of the lighting device auxiliary tool of the present invention will be described in detail. Here, FIG. 1 is a perspective view showing an outline of a configuration in a state in which the lighting device auxiliary tool 20 is attached to the lighting device 10, and FIG. 2 is a perspective view of the lighting device auxiliary tool 20. It is the perspective view which showed the outline of the structure of the state attached to the bottom from the bottom. For reference, FIGS. 3 to 5 show six views of the illumination device auxiliary tool 20. FIG. 3A is a plan view of the lighting device auxiliary tool 20, FIG. 3B is a front view of the lighting device auxiliary tool, and FIG. 4A is a lighting device auxiliary tool 20. 4B is a right side view of the auxiliary device 20 for lighting device, FIG. 5A is a bottom view of the auxiliary device 20 for lighting device, and FIG. ) Is a rear view of the auxiliary device 20 for lighting device. The lighting device auxiliary tool 20 includes a detachable ring 30 attached to the illuminating device 10, a resinous reflecting plate 40, and a coil spring 50 that connects the detachable ring 30 and the reflecting plate 40.

  The illuminating device 10 is an illuminating device that can be used in the same manner as a known incandescent bulb, and can be used by being inserted into an attachment port for the incandescent bulb. For example, when the attachment portion 12 is inserted into the attachment opening 102 provided at the deepest portion of the recess 100 provided on the ceiling, the lighting device 10 can be supplied with electric power. This illuminating device 10 has a plurality of LEDs 14 at the base near the mounting portion 12, and has a light guide plate 16 designed at a position facing the LEDs 14. The light emitted from the LED 14 is diffused in a desired direction by the light guide plate 16 and brightly illuminates the surroundings. At this time, by forming the light guide plate 16 in a desired shape, the pattern drawn by the diffused light can be changed to the desired pattern, so that the design of the light guide plate 16 and the light reflected by the light guide plate 16 An excellent aesthetic can be given by the pattern drawn.

  As shown in FIG. 1, the attachment / detachment ring 30 is a stainless steel circular plate member having an attachment / detachment hole 32 at the center, and a coil spring 50 is attached thereto. The inner diameter of the attachment / detachment hole 32 is larger than the outer diameter of the mounting portion 12 and smaller than the outer diameter of the lighting device 10 as compared with the outer diameter of the lighting device 10. For this reason, when the lighting device 10 is inserted into the attachment / detachment hole 32 from the direction of the attachment portion 12, the outer surface of the illumination device 10 and the attachment / detachment hole 32 are caught and positioned. Further, the three coil springs 50 are respectively provided at positions where the angles formed by the respective intersections of the coil spring 50 and the detachable ring 30 and the virtual center point of the detachable ring 30 are approximately 120 degrees.

  As shown in FIG. 1, the reflection plate 40 is a metal circular plate-like member having an insertion hole 42 into which the illumination device 10 can be inserted at the center. The inner diameter of the insertion hole 42 is larger than the outer diameter of the illumination device 10. Is also big. For this reason, the illumination device 10 can pass through the insertion hole 42. Moreover, the attachment member 44 is attached to the one surface side of the reflecting plate 40 at a position where the angle formed by each attachment member 44 and the virtual center point of the detachable ring 30 is approximately 120 degrees. The other surface side of the reflecting plate 40 is a flat flat surface 41 made of metal, and the light irradiated from the lighting device 10 is reflected by the flat surface 41, whereby a desired pattern can be drawn by the lighting device 10. Furthermore, since the reflecting plate 40 has a circular shape, for example, when a plurality of lighting devices 10 are used side by side on a ceiling or the like, the aesthetic appearance is excellent. Further, for example, when the reflecting plate 40 is a quadrangle, if the directions of the vertices are not the same, a cluttered aesthetic appearance will be given. However, since the reflecting plate 40 is circular, a cluttered aesthetic appearance is given. The possibility can be reduced in advance. In other words, compared with the case where the reflecting plate 40 is a quadrangle, it is possible to give an excellent aesthetic appearance while reducing labor during installation.

  The coil spring 50 is made of metal, and various known coil springs can be used. The coil spring 50 is attached to an attachment member 44 having one end side attached to the attachment / detachment ring 30 and the other end attached to the reflection plate 40, respectively, and urges the attachment / detachment ring 30 and the reflection plate 40 to approach each other. ing. At this time, since the attachment member 44 and the attachment / detachment ring 30 are attached at a position where the angle formed by the virtual center point of the attachment / detachment ring 30 is approximately 120 degrees, the attachment member 44 and the attachment / detachment ring 30 are urged toward the approaching direction. At this time, it is possible to energize while maintaining the mutually parallel state. For this reason, when the reflecting plate 40 is biased in a tilted state, the possibility that the insertion hole 42 and the lighting device 10 come into contact with each other and the reflecting plate 40 or the lighting device 10 is damaged can be reduced. . For example, when the illuminating device 10 is attached to the recessed part provided in the ceiling, a space | gap arises between the reflecting plate 40 and a ceiling surface, and the possibility of impairing aesthetics can be reduced beforehand. In particular, since the light guide plate 16 is an optical path, there is a high possibility that even a slight scratch or light may impair the aesthetic appearance, so that it is significant to keep the reflecting plate 40 and the illumination device 10 from contacting each other.

  Next, the attachment method attached to the illuminating device 10 of this Embodiment comprised in this way and the auxiliary tool 20 for illuminating devices is demonstrated using FIG.6 and FIG.7. Here, FIG. 6 is a cross-sectional view showing the illumination device 10 and the illumination device auxiliary tool 20 in a state before the illumination device 10 is attached to the ceiling, and FIG. 7 is an illumination in a state where the illumination device 10 is attached to the ceiling. It is sectional drawing of the apparatus 10 and the auxiliary tool 20 for illuminating devices. When attaching the illuminating device 10 to the ceiling, as shown in FIG. 6, first, the illuminating device 10 is inserted into the attachment / detachment hole 32 and the insertion hole 42 from the attachment portion 12 side (downward direction in FIG. 6). By doing so, the attachment / detachment hole 32 is caught on the upper part of the illumination device 10, and the attachment / detachment ring 30 abuts on the upper part of the illumination device 10 by its own weight. In this state, the coil spring 50 is kept in a contracted state.

  Subsequently, as shown in FIG. 6, when the lighting device 10 is brought close to the attachment port 102 provided at the deepest portion of the recess 100, the reflector 40 comes into contact with the ceiling surface (the tip position of the recess 100). When the mounting portion 12 of the lighting device 10 is attached closer, the attachment / detachment ring 30 also moves along with the movement of the lighting device 10, but moves because the reflector 40 is in contact with the ceiling surface. I can't. For this reason, the coil spring 50 that connects the detachable ring 30 and the reflecting plate 40 extends, and is urged in a direction in which the distance between the detachable ring 30 and the reflecting plate 40 becomes shorter, and the reflecting plate 40 is applied to the ceiling surface. It will be energized (see FIG. 7). At this time, since the reflecting plate 40 is large enough to cover the entire concave portion, the concave portion cannot be visually recognized by attaching the auxiliary device 20 for the illuminating device to the illuminating device 10 and thus has an excellent aesthetic appearance.

  According to the lighting device auxiliary tool 20 of the present embodiment described in detail above, since the reflecting plate 40 that can cover the entire recess is biased to the ceiling surface, a sense of unity with the ceiling surface can be obtained and excellent. Have a good aesthetic. At this time, since the insertion hole 42 through which the illuminating device 10 can penetrate is provided at the center of the reflecting plate 40, there is no possibility that the aesthetic appearance of the illuminating device 10 itself is impaired.

  Moreover, since the attachment member 44 which connects the reflecting plate 40 and the coil spring 50 is provided on the attachment portion 12 side, it cannot be seen from the outside of the recess. For this reason, possibility that an aesthetics will be impaired by the attaching part 12 or the coil spring 50 connected can be reduced beforehand.

  Further, the lower surface of the reflection plate 40 (the surface located on the side opposite to the detachable ring 30) is a flat surface that can reflect the light emitted from the illumination device 10, and therefore is the light emitted from the illumination device 10. A desired design can be drawn. In other words, the lower surface side of the reflecting plate 40 can have a better aesthetics as compared to a case where light cannot be reflected.

  Furthermore, the attachment / detachment ring 30 that can be attached from above the illumination device 10 is provided, and the reflection plate 40 is biased in a direction approaching the attachment / detachment ring 30 by a coil spring 50 connected to the attachment / detachment ring 30, so that the attachment / detachment ring is provided. By attaching 30 from above the illumination device 10, the illumination device auxiliary tool 20 can be easily attached to the illumination device 10.

  Since the attaching / detaching hole 32 has an inner diameter smaller than the outer diameter of the lighting device 10, when a part of the lighting device 10 is inserted into the attaching / detaching hole 32, the outer diameter of the lighting device 10 is caught by the attaching / detaching hole 32. It is attached to the device 10. At this time, when the coil spring 50 moves in the direction of the mounting portion 12 as the attachment / detachment ring 30 moves and the reflection plate 40 comes into contact with the ceiling surface and the distance between the attachment / detachment ring 30 and the reflection plate 40 increases, the attachment / detachment ring By biasing 30 and the reflecting plate 40 toward each other, the reflecting plate 40 is biased toward the ceiling surface. For this reason, the auxiliary | assistant tool 20 for illuminating devices can be attached to the illuminating device 10 by simple operation of inserting the illuminating device 10 in the attachment / detachment hole 32.

  Further, since the three coil springs 50 that urge the reflecting plate 40 and the detachable ring 30 are arranged at positions where the respective forces are uniform, the reflecting plate 40 is attached in a direction approaching the detachable ring 30. When energizing, it is possible to reduce the possibility that the reflector 40 is inclined more than when energizing with one coil spring. In other words, it is possible to reduce the possibility that the reflecting plate 40 and the lighting device 10 are damaged due to contact, or that a gap is generated between the ceiling surface and the reflecting plate 40 and the aesthetic appearance is impaired.

  In addition, since the LED 14 is provided on the side closer to the mounting portion 12 than the reflection plate 40, and the light emitted from the LED 14 is diffused by the light guide plate 16, the connection for supplying power to the LED 14 and the LED 14 that are light sources It is possible to reduce the possibility that the aesthetics will be impaired by these codes without being visible from the outside.

  In addition, since the LED 14 is used as a light source, the light can be radiated in a straight line on the light guide plate 16 without light diffusing around like an incandescent bulb. For this reason, it is brighter compared with the case where an incandescent lamp having the same luminous intensity is used.

  It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that the present invention can be implemented in various modes as long as it belongs to the technical scope of the present invention.

  For example, in the above-described embodiment, the attachment / detachment ring 30 is attached to the lighting device 10, and the attachment / detachment ring 30 and the reflection plate 40 are connected by the three coil springs 50 to bias the reflection plate 40. The number is not limited to three coil springs 50, and the number may be any number. Preferably, when the lighting device 10 is attached to the recess 100, if the plurality of coil springs 50 are arranged so that the force is evenly applied, the possibility that the reflecting plate 40 is inclined can be reduced. It is possible to reduce the possibility that the device 10 is damaged due to contact, or that a gap is generated between the ceiling surface and the reflection plate 40 and the aesthetic appearance is impaired.

  In the above-described embodiment, the detachable ring 30 is attached to the lighting device 10, and the reflective plate 40 is biased by connecting the detachable ring 30 and the reflective plate 40 with the coil spring 50. As shown in FIG. 8A, a plurality of coil springs 50 connected in series may be used. Even in such a case, it has the same effect as one case. Further, as shown in FIG. 8B, an additional ring 60 may be further provided between the directly connected coil spring 50a and the coil spring 50b, that is, between the detachable ring 30 and the reflecting plate 40. . In this way, the lengths of the coil spring 50a and the coil spring 50b can be shortened as compared with the case where one coil spring is used, so that the possibility that the coil spring contacts and breaks the lighting device 10 is reduced. be able to.

  In the above-described embodiment, the attachment / detachment ring 30 is attached to the lighting device 10, and the attachment / detachment ring 30 and the reflection plate 40 are connected by the coil spring 50 to urge the reflection plate 40. It is good also as what urges the reflecting plate 40 using. In this case, since it is not necessary to provide the detachable ring 30, it is possible to reduce the number of parts and reduce the labor during production while having the effects of the above-described embodiment. Here, FIG. 9 is a perspective view showing an outline of the configuration of the illumination device auxiliary tool 120 that urges the reflector 40 using the conical coil spring 150. For reference, FIGS. 10 to 12 show six views of the illumination device auxiliary tool 120. FIG. 10A is a plan view of the lighting device auxiliary tool 120, FIG. 10B is a front view of the lighting device auxiliary tool 120, and FIG. 11A is a lighting device auxiliary tool. FIG. 11B is a right side view of the lighting device auxiliary tool 120, and FIG. 12A is a bottom view of the lighting device auxiliary tool 120. FIG. B) is a rear view of the auxiliary device 120 for lighting device.

  In the embodiment described above, the reflecting plate 40 is circular. However, the reflecting plate 40 is not limited to a circular shape, and may be a polygonal shape such as a hexagon or an octagon. If it is such a case, even if it is a case where the auxiliary | assistant tool 20 for illuminating devices is attached to the illuminating device arranged in a line, possibility that a complicated image will be given by the direction of a reflecting plate and a beauty | look may be spoiled can be reduced. .

  In the embodiment described above, the lighting device 10 is attached to the recessed portion embedded in the ceiling. However, the installation location of the lighting device 10 is not limited to the ceiling. For example, a known desk lamp or a known stained plate is used. Any lighting fixture can be used as long as it has a portion corresponding to a concave portion such as a downlight such as a glass. In any case, the same effect as that of the above-described embodiment can be obtained.

  In the above-described embodiment, the reflecting plate 40 is made of stainless steel. However, the invention is not limited to this, and other metal plates such as an iron plate and an aluminum plate may be used. A resin-made one may be used instead of the one made of one. If a resin reflector is used, the same effects as those of the above-described embodiment can be obtained while further reducing the weight as compared with a metal reflector.

  In the embodiment described above, the other surface side of the reflecting plate 40 is a flat flat surface 41 made of metal, but the manner of finishing on the other surface of the reflecting plate 40 is not particularly limited. For example, a mirror finish that almost completely reflects the light emitted from the illumination device 10 may be used, or a hairline finish that has thin lines such as hair on the surface may be used. Furthermore, the matte finish which the light irradiated from the illuminating device 10 does not reflect may be sufficient.

  As shown in the above-described embodiments, the present invention can be used as an auxiliary tool attached to the lighting field, particularly to a lighting fixture.
