厚みの薄いシート表面への加工は困難であつた。[Detailed Description of the Invention] This invention relates to a light-transmitting plate for lighting equipment that has a hairline and can be mass-produced. Conventionally,
Most of these types of translucent plates are made by forming concave stripes on the surface of the synthetic resin plate using a brush-like object, or by sandblasting, but these methods do not damage the plate surface. As a result, parallel grooves were formed, making the grooves uneven and causing diffuse reflection due to the different refraction directions of light.
It was difficult to process the surface of a thin sheet because it whitened the sheet surface and damaged the board surface.

成させるものである。 This invention aims to eliminate the drawbacks of the conventional methods described above, and includes a part in which a large number of parallel protrusions are formed in a desired direction on a mold prepared in advance, and a part in which a large number of parallel protrusions are formed in a different direction. The above-mentioned protrusions are placed on a synthetic resin plate placed on this mold by applying heat pressure using a heat press or the like to transfer the arrangement of the above-mentioned protrusions, thereby forming concave parts on the plate surface. This is what causes the formation of strips.
また、上記異る方向の多数の平行凸条の組の境
界により形成する輪郭線によつて、所望の模様形

じる照明器具用透光板とすることもできる。 In addition, a transparent plate for lighting equipment that forms a desired pattern shape by the contour lines formed by the boundaries of the sets of a large number of parallel protrusions in different directions, and allows the illumination light to pass through to create a beautiful pattern. It is also possible to do this.

ある。 Furthermore, the cross-sectional shape, thickness, and depth of the hairline groove can be changed, and it can be made opaque so that only transmitted light from a certain direction is transmitted.

のである。 To explain this with the examples shown in the drawings, Fig. 1 is a perspective view illustrating the manufacturing process of a transparent plate, and 1 is a mold, which is often made of stainless steel, brass, etc. On the surface of the mold 1, convex strips 3, 3', 3'', etc. corresponding to hair lines are formed. set of protrusions 3, 3',
3"... is formed on the mold 1 by an appropriate method (corrosion, cutting, etc.). 2 is a sheet made of synthetic resin (vinyl chloride, acrylic resin), and the thickness is determined according to the need. This idea is
It is also possible to form a thin sheet; in that case, the parallel protrusions are first copied from a mold onto an elastic plate, and then the sheet is placed on the elastic template and heated and pressed. to form the desired hairline. FIG. 2 shows another embodiment, in which numeral 4 has a pattern with a floral outline made of hair lines in different directions in the center, and at the same time, the other parts of the transparent plate 2 have parallel grooves. It is formed as follows.
上記の加熱加圧工程は、例えば、0.2mm厚の塩
化ビニールを用い、50〜80℃の温度において、５
秒程度加圧することにより容易に得られる。 The above heating and pressing process uses, for example, 0.2 mm thick vinyl chloride at a temperature of 50 to 80°C.
It can be easily obtained by applying pressure for about seconds.
以上のとおり構成されているので、金型上に正
確に刻まれているヘアーラインの凸条を転写する
だけで同一溝のヘアーラインを構成できるので、
従来のもののように白色乱反射を生じないばかり

めて効果のあるものである。 With the structure described above, hairlines with the same groove can be constructed simply by transferring the ridges of the hairline that are accurately carved on the mold.
Not only does it not cause white diffused reflection like conventional products, but it also produces a rainbow spectrum due to the light rays reflected in a certain direction, making it beautiful and extremely effective for lighting equipment.
その上、薄いシートにも加工ができ、量産も可

れた効果をもつものである。 Moreover, it can be processed into thin sheets and mass-produced.In addition, by combining parallel stripes in different directions as in the above example, different light reflections can be formed, and different patterns can be created. The result is an excellent effect that does not require complicated processing unlike conventional methods.
