Description

  The present invention relates to a wooden lighting fixture shade that can be used for various lighting fixtures, and a lighting fixture using the same.

Conventionally, various types of shades for lighting fixtures used in lighting fixtures have been provided,
In particular, there is an indirect lighting device that gives a soft impression. In particular, a thin wood sheet pasted on a resin sheet is known, but such a shade for lighting equipment has a problem that the resin sheet and the wood sheet are peeled off due to heat from the light source. Become. As a countermeasure, for example, in Patent Document 1, a non-woven fabric that escapes the effect of heat is pasted on the surface of sliced wood to form a wood grain sheet, and a transparent plastic plate is provided on the surface of the wood grain sheet on the nonwoven fabric side, so It is a wood-coated decorative board.

JP 2002-144383 A

  The translucent grained decorative board of Patent Document 1 is manufactured by pressing a wood grain sheet on the outer periphery of a cylindrical transparent acrylic board by a roll press. Further, the same document describes that when the transparent acrylic plate has a complicated shape with irregularities, it may be manufactured using a vacuum press. However, even if a vacuum press is used, in order to prevent wrinkles and the like, it is necessary to use a considerably thin wood grain sheet. If the wood grain sheet is too thin, the texture of light transmitted through the wood is lowered, and there is a disadvantage that good design properties cannot be obtained. Furthermore, since it is necessary to manufacture using a press, there also exists a problem that manufacturing cost increases.

  Therefore, in view of the above-mentioned problems of the prior art, the present invention provides a lighting fixture shade capable of obtaining a good design property even with a complicated shape and suppressing the manufacturing cost, and a lighting fixture using the same. The purpose is to provide.

In order to achieve the above object, the following technical measures were taken.
That is, the shade for lighting fixtures of the present invention is a shade for lighting fixtures including a shade body surrounding a light source, and the shade body is formed of wood adjusted to a thickness having translucency. It is what.
If it is the shade for lighting fixtures of the said invention, since a shade main body is formed with the timber adjusted to the thickness which has translucency, it manufactures without taking the conventional manufacturing method using a roll press or a vacuum press. be able to. Thereby, even if it is a complicated shape, it is not necessary to make a wood part thin, and the texture of the light which permeate | transmitted the wood is not reduced. Further, since it is only necessary to form the wood into a required shape, the production cost can be reduced as compared with the conventional case.

  Various kinds of wood can be used as the wood, and among them, old pine is preferable, and preferably has a thickness of 1.6 mm to 2.2 mm. By using an old pine material having a thickness of 1.6 mm to 2.2 mm, it is possible to improve the texture of light transmitted through the wood.

  The shade body is preferably formed so as to surround substantially the entire light source. If the shade body has such a shape, the light source cannot be seen from the outside, and the design can be improved.

  The shade body can be formed into a light bulb shape along the shape of the light source by, for example, a first member having a bowl shape and a second member having a cylindrical shape combined with the first member. In this case, an impression can be given as if a wooden light bulb is emitting light.

The luminaire of the present invention is a luminaire including a light source and a luminaire shade surrounding the light source, and the luminaire shade is the luminaire shade described above. is there.
According to the lighting apparatus of the present invention, the shade main body is formed of wood adjusted to a light-transmitting thickness, so that it can be manufactured without using a conventional manufacturing method using a roll press or a vacuum press. it can. As a result, the texture of light transmitted through the wood is not reduced. In addition, since it is only necessary to form the wood into the required shape, the production cost can be reduced compared to the conventional method.

  As described above, according to the present invention, since it is manufactured without using a conventional manufacturing method using a roll press or a vacuum press, the texture of light transmitted through the wood is not lowered, and a good design property is achieved. Obtainable. Further, since it is only necessary to form the wood into a required shape, the production cost can be reduced as compared with the conventional case.

It is a front view which shows the lighting fixture which concerns on the 1st Embodiment of this invention. It is a longitudinal cross-sectional view of a lighting fixture. It is a front view of the shade for lighting fixtures of a lighting fixture. (A) is a top view of the shade for lighting fixtures, (b) is a bottom view of the shade for lighting fixtures. It is explanatory drawing which shows the state which installs the shade for lighting fixtures in a light bulb part.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing a lighting fixture 1 according to the first embodiment of the present invention, and FIG. 2 is a longitudinal sectional view of the lighting fixture 1. The luminaire 1 includes a light bulb portion 2 as a light source and a luminaire shade 3 provided in the light bulb portion 2. The light bulb portion 2 includes an LED type light bulb 4 and a socket 5 to which the light bulb 4 is connected. Electric power is supplied through the socket 5 and the light bulb 4 is turned on.

  As shown in FIG. 2, the socket 5 has a cylindrical portion 6 formed with a required thickness and depth to which the light bulb 4 is connected and into which the shade 3 for a lighting fixture is fitted. The lighting fixture shade 3 includes a shade body 7 that surrounds the light bulb 4. As shown in FIGS. 3, 4 (a) and 4 (b), the shade body 7 includes a first member 8 having a bowl shape and a second cylindrical member that is combined with the first member 8 and is narrowed to one side. 9 is formed into a light bulb shape along the shape of the light bulb 4.

  A step portion 11 having an inner peripheral wall portion 10 is provided on an edge portion 9a on the large diameter side (upper side in FIG. 2) of the second member 9, and the edge portion 8a of the first member 8 is provided on the step portion 11. The first member 8 and the second member 9 are combined with each other. The outer diameter of the inner peripheral wall portion 10 of the step portion 11 of the second member 9 is slightly larger than the inner diameter of the edge portion 8a of the first member 8, and the first member 8 and the second member 8 combined with each other are combined. The member 9 is not easily detached.

  A cylindrical fitting portion 12 is formed on the small diameter side (the lower side in FIG. 2) of the second member 9, and this fitting portion 12 is fitted into the cylindrical portion 6 of the socket 5. The outer diameter of the fitting portion 12 is slightly larger than the inner diameter of the cylindrical portion 6 so that the fitted shade body 7 is not easily detached from the socket 5. With the configuration as described above, the shade body 7 (shade 3 for lighting fixture) surrounds substantially the entire bulb 4, and when the lighting fixture 1 is viewed, the bulb 4 cannot be seen at all. ing. Thereby, the impression as if a wooden light bulb is emitting light can be given, and the design of the lighting fixture 1 can be improved.

  The shade body 7 is made of wood adjusted to a thickness having translucency. This wood is made of old pine wood. The thickness of the wood forming the shade body 7 in the present embodiment is 1.6 mm to 2.2 mm, and the upper limit is more preferably 1.8 mm. If the lower limit value of the thickness is smaller than 1.6 mm, the strength of the shade body 7 is reduced, so that the luminaire shade 3 is easily broken and the light from the light bulb 4 is excessively transmitted, so that a good light texture can be obtained. Absent. If the upper limit value of the thickness exceeds 2.2 mm, the light from the light bulb 4 is hardly transmitted, and a good light texture cannot be obtained. That is, by setting the thickness of the wood as described above, the strength resistance of the lighting fixture shade 3 can be maintained, and a good light texture can be obtained.

  The wood to be used is not limited, and various kinds of wood such as cedar, cypress, zelkova, tochi, camphor, beech can be used. In particular, the texture of light transmitted through the wood can be remarkably improved by using an old pine material having a thickness of 1.6 mm to 2.2 mm as in the present embodiment. The thickness of the shade body 7 is adjusted according to the type of wood. FIG. 5 is an explanatory view showing a state in which the lighting fixture shade 3 is installed in the light bulb portion 2. As shown in this figure, after the second member 9 is provided in the light bulb part 2, the shade member 7 (lighting device shade 3) is attached to the light bulb part 2 by combining the first member 8 with the second member 9. Install.

  If it is set as the lighting fixture 1 of this embodiment, and the shade 3 for lighting fixtures, since the shade main body 7 is formed with the timber adjusted to the thickness which has translucency, conventional manufacture using a roll press or a vacuum press It can be produced without taking a method. Thereby, even if it is a light bulb type like this embodiment or other complicated shapes, it is not necessary to make the wood part thin, so that the texture of light transmitted through the wood is not lowered and is good. Design properties can be obtained. Furthermore, since it is only necessary to form the wood into a required shape, the production cost can be reduced as compared with the conventional case.

  The above embodiment is illustrative and not restrictive. For example, the texture of the light transmitted through the shade body may be partially changed by partially changing the thickness of the wood forming the shade body. Further, the thickness of the wood may be further reduced according to the strength required for the lighting fixture and the light texture required for the lighting fixture. You may change the texture of the light which permeate | transmitted by forming an uneven | corrugated pattern in a shade main body. Further, the shade main body may be elongated according to the elongated fluorescent lamp, or may be other shapes such as a square shape. As the light source, an LED type is used in the present embodiment, but an incandescent lamp type or a fluorescent lamp type may be used.

  When the shade main body is formed so as to surround the light source as in the present embodiment, a heat radiating hole penetrating the front and back for releasing heat generated from the light source may be provided in the shade main body. The position of the heat radiating hole is changed depending on the position of the shade body or the light source. In the present embodiment, the heat radiating effect is particularly high if provided near the edge of the second member on the large diameter side. The scope of the present invention is not limited to the above-described embodiment, but is indicated by the scope of the utility model registration request, and includes all modifications within the meaning and scope equivalent to the scope of the utility model registration request. .
