Description

[Detailed description of the invention] This release F! A relates to a method of manufacturing a lighting fixture shade, and its purpose is to create a fine pattern with high precision on the transparent surface material that constitutes the side plate of the shade, and also to improve the strength of the transparent curved material.

An embodiment of this invention will be explained using FIG. 1.

In other words, the manufacturing method of this lighting fixture shade is as shown in FIG. A decorative veneer 1 having a thickness of 0.2 to 0.sm as shown in (a) is obtained. Then, a colored resin sheet 2, if necessary, is laminated onto one side of the decorative veneer 1 via an adhesive. Thereafter, as shown in FIG. 1(b), a colored or transparent resin 3 such as cretan, polyester, or amino is sprayed onto the other surface of the decorative veneer 1 to form three coating layers 4.

Next, as shown in FIG. 1(C), a laser beam 5 is irradiated from the side of the coating layer 4 to form a pattern 6, thereby obtaining a transparent curved material 7. Finally, as shown in FIG. 1(d), the light-transmitting curved material 7 is stretched around the circumferential surface of the prismatic stand frame to form the shade 8 of the lighting stand.

When this shade 8 is turned on with a power source inside, the pattern 6 of the translucent surface material 7 is thinner than the other parts, so the pattern 6 shines more strongly than the other parts and stands out. visible and exhibits excellent design effects.

In this way, since the pattern 6 is engraved by irradiating the coating layer 4 with the laser beam 5, in other words, it is not necessary to directly etch the decorative veneer 1 with the laser beam 5 in order to form the pattern 6. Even if the decorative veneer 1 is carved, the depth of the groove will be very small, so the decorative veneer 1
The tension of the light-transmitting surface material 7 hardly decreases, and therefore the strength of the light-transmitting surface material 7 can be set high despite having the pattern 6.

Further, the coating layer 4 of the transparent surface material 7 and the resin sheet 2 prevent the decorative veneer 1 from cracking. Furthermore, since the pattern 6 is formed on the coating layer 4, it is possible to form the fine pattern 6 without causing partial loss of the pattern as would be the case when the pattern is formed on the decorative veneer 1. Furthermore, the edges of pattern 6 are finished sharply. Moreover, the coating layer 4 is made of colored paint.
When a pattern 6 is formed, the color of the pattern 6 stands out and the lighting effect becomes great, and it is also possible to express colors according to the pattern 6. Moreover, since the decorative veneer 1 and the resin sheet 2 are laminated before the laser treatment, poor adhesion between the two and misalignment of the pattern 6 can be prevented.

The specific conditions in the above embodiment of the method for manufacturing this lighting fixture shade are listed below.

Example 1 (1) Decorative veneer l...Rose board pattern using Wawa wood, 0
．． 3fi thick decorative veneer.

(2) Resin sheet 2: A transparent sheet made of polypropylene and having a thickness of 0.511 m1.

(3) Paint layer 4: Colored paint layer made of Frethane resin.

(4) Laser treatment...Creating a human figure on the coating layer.

According to this Example 1, the strength of the light-transmitting surface material 7 was strong, and the fine parts of the human image could be formed sharply, making it possible to manufacture a shade in which the human figure appeared to stand out.

Example 2 (1) Decorative veneer 1: Decorative veneer with teak grain pattern and 0.4-inch thickness using jelutong material.

(2) Resin sheet 2: Made of polypropylene. , s si thick transparent sheet.

(3) Paint layer 4: Colored paint layer made of amino resin.

(4) Laser treatment...Flower patterns are formed on the coating layer.

According to this Example 2, the strength of the translucent surface material 7 was strong, and the fine parts of the floral pattern could be formed sharply, making it possible to manufacture a shade in which the floral pattern stood out.

Another embodiment of the invention will be described with reference to FIG. This lighting fixture manufacturing method involves laminating a resin sheet 10 on both sides or one side of a decorative veneer 90 shown in FIG. As shown in Figure 2(b), the laser beam 1
1 is irradiated to form a pattern 12 to form a transparent surface material 13,
A shade 14 shown in FIG. 2(C) is formed by combining the light-transmitting surface material 13 and the light-transmitting surface material 13. That is, compared to the above embodiment described using FIG.
The only difference is that a pattern 12 is formed in accordance with No. 1, and the rest is the same as that of the above-mentioned embodiment, and the same effects as those of the above-mentioned embodiment can be achieved.

The specific conditions in the above embodiment of the method for manufacturing this lighting fixture shade are listed below.

Example 3 (1) Decorative veneer 9: Decorative veneer with teak straight-grain pattern and 0.3sI thickness using Ickx wood.

(2) Resin sheet 10--A colored sheet made of polypropylene and having a thickness of 0.5 fi.

(3) Laser processing: engraving a floral pattern on a resin sheet.

According to this Example 3, the strength of the light-transmitting surface material 13 was strong, and even the minute parts of the flower pattern could be formed sharply, making it possible to form a shade in which the flower pattern appeared to stand out.

Example 4 (1) Decorative veneer 9: Decorative veneer made of agathis wood with a cypress board grain pattern and 0.3 cod thickness.

(2) Resin sheet 10: 0.5 tm thick colored sheet made of polyethylene sheet.

(3) Laser treatment: Creates a floral pattern on a resin sheet.

In this Example 4 as well, the strength of the translucent surface material was strong, and even the minute parts of the floral pattern could be formed sharply, making it possible to form a shade that made the floral pattern stand out.

As described above, the method for manufacturing a lighting fixture shade of the present invention involves irradiating a laser beam onto a transparent resin layer such as a coating layer or a resin sheet laminated on one surface of a decorative veneer to create a patterned transparent shade. By shaping the face material and combining this translucent face material to form a shade, it is possible to accurately engrave fine patterns on the translucent face material, and it also has the effect of improving the strength of the translucent face material. be.
