  Certainly, both the lighting device disclosed in Japanese Patent Laid-Open No. 6-275115 and the lighting device disclosed in Japanese Patent Laid-Open No. 2000-268611 can be easily replaced with new ones because the caps are detachably attached to the main body. Alternatively, it is easy to change the color pattern or the like. However, even if the replacement of the umbrella is easy, the deterioration of the umbrella cannot be delayed.

  Therefore, the present invention solves the above-mentioned problems and can deal with exchanges and changes in color patterns, etc., accompanying deterioration, and with regard to deterioration, the progress of deterioration is delayed to maintain the beauty of the decoration or exchange. It is an object of the present invention to provide a lamp shade that can increase the time to the lamp and a lamp using the lamp shade.

  As a result of diligent research, the present inventor was able to obtain the knowledge that the deterioration of the lampshade is accelerated when the beautiful decorative part touches the air. The beautiful decorative part is near the light source, and the oxygen in the air that continues to be supplied to the decorative part promotes sunburn.

  That is, the above-mentioned problem is a translucent lampshade provided in the vicinity of a light emitting source, in which a decorative layer made of craft Japanese paper or the like is sandwiched between an inner layer and an outer layer. These three layers are all translucent, and the decorative layer is provided between the inner layer and the outer layer so as to be detachable and replaceable and sealable so as not to be exposed to the outside air. This is achieved by the characteristic lamp shade. In addition, the translucency here means that the material is transparent, the surface is provided with irregularities, a lot of lens-like things, a rubbed glass-like material, a material that is translucent, Although it is arbitrary, for example, a bubble or a substance having a different refractive index is put inside, it can be said that it is not opaque anyway and light from the light emitting source can pass therethrough.

  The three layers constituting this lamp shade, namely the inner layer and the outer layer, and the decorative layer made of craft Japanese paper or the like sandwiched between them have translucency, and thus serve as a lamp shade. Can be fulfilled. In particular, the presence of a decorative layer makes this lamp shade emit beautiful light. The decorative layer is sandwiched between originally clear materials such as glass and an acrylic plate to protect the surface. The decorative layer can be removed and replaced between the inner layer and the outer layer, but when the new decorative layer is sandwiched between the inner layer and the outer layer, the new decorative layer is connected to the inner layer and the outer layer. Since it can be sealed so that it is difficult to touch the outside air, it is possible to delay the progress of deterioration because the beautiful decoration layer is difficult to touch the air, to keep the decoration beautiful and to increase the time to exchange Has succeeded.

  Such a lamp shade can be mounted so as to surround the light source, or can be placed in front of the light source. In many cases, a so-called desk lamp or the like is configured as the former, and a wall lamp or the like is configured as the latter. In the former case, if it is assumed that a vent hole for venting air heated by the light emitting source is formed in the upper part, it is easy to vent the hot air inside the lamp shade upward.

  By the way, regarding the lamp shade according to the first aspect, the inner layer and the outer layer can be in close contact with each other at the engaging portion provided at the overlapping edge thereof. Since the inner layer and the outer layer are in close contact with each other at the engaging portion and the entire circumference is closed, it is difficult for air to enter between the inner layer and the outer layer. The progress of deterioration of the decorative layer sandwiched therebetween is delayed.

  The lamp with a lamp shade according to the present invention is provided with a lamp shade in the vicinity of the light source, and the lamp shade is formed by sandwiching a decoration layer between an inner layer and an outer layer. These three layers are all translucent, and the decorative layer is provided between the inner layer and the outer layer so as to be detachable and replaceable and sealable so as not to be exposed to the outside air. Features. With regard to such a lamp, the lamp shade can be mounted so as to surround the light source or can be placed in front of the light source. In the former case, if an air vent hole for venting air heated by the light emitting source is formed in the upper part, the hot air inside the lamp shade can be easily drawn upward.

  Further, the inner layer and the outer layer can be brought into close contact with each other at an engaging portion provided at the overlapping edge portion. The reason why the inner layer and the outer layer are kept airtight is that the inner layer and the outer layer are brought into close contact with each other by the engaging portion so that the entire circumference is closed.

  According to the present invention, since a beautiful decorative layer made of craft Japanese paper or the like can be exchanged, the mood can be changed by exchanging with a favorite one depending on the situation. In addition, since this decorative layer is sandwiched between the inner layer and the outer layer and hardly touches the outside air, it is difficult to deteriorate and can be made to last for a long time. The decorative layer is extremely resistant to dirt.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to these embodiments, and various variations can be given.

The shade 1 sandwiches a decorative outer tube 10 having a cylindrical shape with a closed top and a decorative tube 14 made of craft Japanese paper with flowers in the inner tube 12. It consists of. The shade 1 is obtained by setting the decorative cylinder 14 inside the outer cylinder portion 10 and setting the inner cylinder portion 12 further inside.

  At this time, the fitting edge 11 which is a recess formed over the entire circumference of the lower edge of the outer cylinder 10 is fitted into the fitting edge 11 which is a protrusion formed over the entire circumference of the lower edge of the inner cylinder 12. When the marginal part 13 is fitted, this part is in close contact, and the gap between the outer cylinder part 10 and the inner cylinder part 12 is sealed, and the decorative cylinder 14 contained in this gap is isolated from the outside air. (FIG. 2). Therefore, the decorative cylinder 14 is not easily deteriorated and has a long life.

  The decorative cylinder 14 seen through the light from the light bulb B is beautiful and has a unique atmosphere unique to craft Japanese paper. However, if you want to change it to another pattern or material, The fitting edge portion 13 of the cylinder portion 12 is removed from the fitting edge portion 11 of the outer cylinder portion 10 so as to float, and the inner cylinder portion 12 is pulled out from the outer cylinder portion 10 as it is. As a result, the decorative cylinder 14 can be taken out.

Second Embodiment A shade 3 according to this embodiment has a cylindrical shape with a top and bottom blow-off, and a cap 4 for keeping the gap between the outer cylinder portion 30 and the inner cylinder portion 31 airtight is crowned on the upper and lower edges. (Fig. 3).

  That is, the shade 3 has a craft Japanese paper decorative cylinder 34 (here, the craft Japanese paper is rolled up) by a transparent outer cylinder portion 30 and an inner cylinder portion 31 that are formed in a cylindrical shape and are opened at the top and bottom by an upper opening 32 and a lower opening 33. It is made up of sandwiched items). The shade 3 is obtained by setting the decorative cylinder 34 inside the outer cylinder part 30, setting the inner cylinder part 31 further inside, and fitting the cap 4 into the upper opening 32 and the lower opening 33. . The cap 4 is provided with a fitting recess 40 over the entire periphery, and is fitted into the upper and lower edges of the outer cylinder portion 30 and the inner cylinder portion 31 with the decorative cylinder 34 sandwiched in the fitting recess 40. is there.

It becomes. When it is desired to replace the decorative cylinder 34 with another one, the cap 4 is removed from the upper and lower edges of the shade 3 and the inner cylinder 31 is pulled out from the outer cylinder 30 and the decorative cylinder 34 is taken out.

Third Embodiment A shade 5 according to this embodiment is similar to the shade 3 according to the second embodiment described above, except for the outer cylinder portion in the following points. That is, the outer cylinder part is a cloth-made light-shielding body, but the central part of the light-shielding part 50 is opened and a window part 51 is provided. The inner cylinder is a transparent cylinder (FIG. 4).

  A decorative film 52 made of a color film on which a picture is baked is sandwiched between the inner cylinder part (not shown) and the outer cylinder part. In this way, the light from the light bulb shines brightly on the decorative film 52 to create a mood. Although the decorative film 52 is kept airtight and has a long life, it can be exchanged so that the mood can be changed by changing to a desired one depending on the situation.

  The lamp shade and the lamp of the present invention can be freely selected by the designer as to the material and shape of the components constituting the lamp shade and the lamp. Examples of configurations for maintaining the airtightness of the decorative layer include the above-described fitting between the fitting edges of the outer cylinder 10 and the inner cylinder 12, and the upper and lower edges of the outer cylinder 30 and the inner cylinder 31. In addition to the cap 4 having the fitting recess 40 to be fitted into the part, for example, as another configuration example of the third embodiment described above, a circular filling is provided on the back surface of the window part provided in the light shielding part 50 of the outer cylinder part.
