Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a lighting fixture capable of exchanging a picture expressed on a light transmitting member and a material of the light transmitting member.

[0002]

[Prior art]

 Lighting fixtures, especially those that are installed indoors and have a high specific gravity relative to the decorativeness of the interior, are designed with a light-transmitting cover that surrounds the light source. There is an image in which light transmittance is changed and a pattern or the like is expressed by, for example, a “watermark”.

In the latter case, by attaching Japanese paper to the front part of the outer frame, which is known as a lantern, a lighting fixture of soft light utilizing the texture can be obtained. However, it was troublesome to attach Japanese paper etc. from the inside to the frontage of the outer frame once assembled, and it was not suitable for changing or replacing pictures later.

 In order to achieve the above object, the lighting fixture of the present invention is formed in a polygonal cylindrical shape by a plurality of columns erected in parallel with each other and beams connecting the columns, and a light source is provided at the center thereof. It is composed of a main body frame arranged, and a plurality of translucent panels arranged at a portion corresponding to a side surface of the polygonal tube of the main body frame. The translucent panel has an appropriate pattern at a central portion of an outer frame. And a pair of slits is formed along the longitudinal direction of the strut on the opposing side surfaces of the adjacent strut of the main body frame, and a pair of slits are formed on the opposing side strut of the main frame. The two side edges of the outer frame of the light-transmitting panel are supported by the slits in an inserted state, and one end of the pair of slits is opened so that the light-transmitting panel can be inserted and removed in the longitudinal direction of the column.

[0006]

[Embodiment of the invention]

 1 to 3 show a lighting apparatus 1 according to an embodiment of the present invention. In the figure, a lighting fixture 1 is formed in a square tubular shape by one main body frame 2 and four translucent panels 3.

In the main body frame 2, four columns 12 are erected in parallel on the upper surface side of the base plate 11, and adjacent columns are connected to each other by beams 13, 14, 15 consisting of three steps of upper, middle and lower. As shown in FIG. 3, the inside of the portion where the middle stage beam 14 is provided is connected in an X-shape by light source support plates 16 and 16 also serving as struts, and a light source is provided at the intersection of the light source support plates 16 and 16. A socket 18 of a certain bulb 17 is fixed.

As shown in FIG. 2, each of the beams 13, 14, 15 is fitted into a longitudinal groove 12a (or tenon) formed along the longitudinal direction on a side surface of each of the columns 12 with respect to the adjacent column 12. At the same time, the support plates 19 and 20 are fitted and fixed in the vertical grooves 12a over the entire length of the upper, middle and lower steps between the beams. Further, a rod-shaped support member 21 is fixed to the inner side surface of each column 12 along the longitudinal direction of the column 12, and two perpendicular side surfaces of the support member and an upper middle beam positioned parallel to both sides thereof. Slits 22 and 22 are formed between the support plates 19 and 19 between 13 and 14.

The translucent panel 3 has a translucent sheet member 32 stretched over an outer frame 31 having a thickness that can be inserted into the slits 22, 22, and an upper end surface of the outer frame 31 is provided with a translucent panel 3. A top plate 33 also serving as a lid closing the open end 22e of the slit 22 exposed at the upper end of the main body frame 2 is fixed in a state where is inserted into the main body frame 2. As shown in FIG. 2, both ends of the top plate 33 are slanted so that adjacent top plates 33 are combined with each other.

The translucent sheet material 32 is a thin translucent (diffuse translucent) sheet material such as paper, and is preferably made of Japanese paper in terms of decorativeness. In particular, white watermarks, black watermarks, etc., can be used to express an appropriate pattern by inserting, or a plastic surface, such as embossing or laser processing, to represent a pattern, and furthermore, a paper drawing process. It is preferable to use a material whose surface has been subjected to a texture treatment such as a texture or texture, or a material expressing a pattern or pattern on paper by coloring, but is not particularly limited.

As a method of stretching the translucent sheet material 32 on the outer frame 31, the light-transmitting sheet material 32 may be directly adhered by an adhesive means such as glue, an adhesive, a double-sided adhesive tape, or may be attached to the back surface of the outer frame 31. A fixing frame (not shown) whose outer periphery is slightly smaller than the outer frame 31 is fixed by means of screws or the like, and the translucent sheet material 32 is sandwiched between the fixing frame and the outer frame 31. At this time, the fixing frame may be independent for every four sides of the outer frame 31. The clamp may be formed by utilizing the elasticity of a spring or the like.

Then, the translucent panel 3 configured as described above is inserted from above into between the pair of slits 22 of the main frame 2 as shown in FIG. In this state, the open end 22 e of the slit 22 at the upper end of the main body frame 2 is closed by the top plate 33 of the translucent panel 3.

Since the translucent panel 3 is fixed only by being inserted into the slit 22 as described above, the translucent panel 3 can be easily removed by being pulled out above the main body frame 2, and the translucent sheet material 32 can also be replaced. Thus, the pattern and pattern expressed on the translucent sheet material 32 can be changed, so that the selection of the pattern and material suitable for the installation space and the selection according to the user's preference are possible.

In the above-described embodiment, the case where the main body frame 2 is in the shape of a square tube is shown. However, the present invention is not limited to this, and may be a polygonal tube such as a triangular tube, five, or hexagonal tube. can do. Also, each of the translucent panels 3 is rectangular, but may have a different width, that is, it does not have to be a regular polygonal cylinder. In this case, the shape of each translucent panel becomes the same, which is advantageous not only in terms of cost but also in that there is an advantage that the translucent panel 3 can be exchanged between the respective surfaces of one lighting fixture 1. Further, instead of forming the slit 22 by the support plates 19 and 20 and the support member 21, the slit 22 may be formed directly on each of the columns 12.
