Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device or a stair step or hand fold using a light source such as a light emitting diode and a light transmitting body such as an optical fiber.

[0002]

2. Description of the Related Art Hitherto, as a light source of an illuminating device, a light emitting diode has been frequently used in addition to a light bulb, a neon tube or a fluorescent lamp, and a light transmitting body such as an optical fiber for transmitting light from such a light source has been proposed. . Such an optical transmission body is formed into a rod shape with a resin, and when light emitted from a light source such as a light emitting diode enters from one end side, the light is transmitted in the length direction of the optical transmission body. However, a conventional optical fiber or the like cannot be used as a light source of a lighting device because the directivity of light is strong and the emissivity of light to the side surface is low. Therefore, a technique has been proposed in which light from a light source is emitted to the side surface by filling such an optical transmission body with a scattering material for scattering light or forming a reflecting material on the side surface. For example, JP-A-2000-39520 discloses that
A technique has been disclosed in which a reflective material is formed between a tubular glad and a core so that light is emitted from a side surface to effectively increase luminance. Therefore, by using such an optical transmission body together with a light source such as a light-emitting diode, it becomes possible to use the light transmission body as a step or a hand fold having a lighting device or a light-emitting portion.

[0003]

However, when the above-described optical fiber such as an optical fiber is actually used as a component of a lighting device or the like, it is necessary to support the optical fiber in a stable state. . In particular, when the rod-shaped optical transmission body is formed of resin, the smaller the outer diameter is, the more fragile it is, and the more likely it is to be easily damaged by an external force. In addition, stair steps or hand folding using the above-described optical transmission element as a constituent element require that a stable supporting state of the optical transmission element be sufficiently ensured.

Accordingly, the present invention has been proposed to solve the problems of the above-described lighting apparatus and stair steps or hand folds using an optical transmission body such as an optical fiber as a component. It is an object of the present invention to provide a lighting device or a stair step or a hand fold that can secure the most stable support state with a very low possibility that a transmission body is dropped or damaged.

[0005]

It is characterized in that a reflector for radiating light from the transmission body to the outside is provided.

In the first aspect of the present invention, the above-mentioned optical transmission body may have any name as long as it has at least optical characteristics for transmitting light from a light source from one end to the other end. Regardless. Further, this optical transmission body needs to be formed into a rod shape with resin. As the resin material, polystyrene, polycarbonate, acrylic resin, or the like can be used. Note that the outer shape of this optical transmission body does not necessarily need to be formed in a cylindrical shape,
For example, it may be shaped into a polygonal column such as a pentagonal column, a hexagonal column, or an elliptical column. The support for supporting the optical transmission body is required to be formed to be longer than the optical transmission body, and to be formed with a concave groove exposing one side of the optical transmission body. Since this concave groove supports the optical transmission body, it corresponds to the shape of the optical transmission body, but at least if the supported optical transmission body is formed so as to be exposed linearly. good. However, it is preferable that at least half of the optical transmission body is supported by the concave groove. Further, in the present invention, it is necessary that at least one of the back surface and the concave groove of the optical transmission body is provided with a reflecting material for radiating light from the optical transmission body to the outside. In the case where the reflecting member is provided on the light transmitting member, the reflecting member does not need to be provided on the support, and the light transmitting member which is formed into a rod shape with acrylic resin or the like is used. In this case, a reflecting material is attached or coated on the back surface of the optical transmission member (the surface opposite to the exposed surface of the optical transmission member supported by the support), or the concave groove formed on the support is formed.

As a result, since the stable supporting state is ensured, even when the outer diameter of the optical transmission body is small, it is possible to effectively avoid the risk of being damaged by an external force. In particular, when the support is extruded from aluminum or resin, not only the manufacturing cost is reduced, but also the optical transmission body can be supported in a more stable state.

Light from the diode is transmitted downward from above through the optical transmission body, and is radiated outside by being reflected by the reflector. In the present invention, since the optical transmission body is inserted and supported in the concave groove formed in the support, like the first and second inventions,
Even when an optical transmission body with a small outer diameter is used as a component,
A stable support state can be secured.

Since it is inserted and supported in a concave groove formed in either the upright plate portion or the horizontal plate portion constituting the step main body, even when a load of a person or an object acts on the optical transmission body, it is easy. It will not be damaged. In particular, when this concave groove is formed in the upright plate portion constituting the step main body, a rubber plate for preventing slippage is attached to the horizontal plate portion, or unevenness for preventing slippage is formed in the horizontal plate portion. In addition to this, the light radiated from the optical transmission body can be irradiated to the horizontal plate portion, and the risk of damage to the optical transmission body can be further avoided. In the fourth invention,
