Abstract

<P>PROBLEM TO BE SOLVED: To provide a lighting system whereby two kinds of illumination service can be selected. <P>SOLUTION: This lighting system is equipped with an emitter 3 provided with a cylindrical body 2 having a light source 1 such as a light emitting diode in it with an opening at its one end, and a light guiding body 4 which can be inserted in the opening and can emit light from the light source 4 to the outside after bringing the light into it, and use of direct light from the emitter 3 (refer to figure 2) or use of the light by combination of the emitter 3 and the light guiding body 4 (refer to figure 1) can be selected in this lighting system. The light guiding body 4 has an almost C-shaped cross section so as to be able to emit light brought in from its end part from its side, and the almost C-shaped surface 5 is made to carry a light scattering and reflecting function. For example, well known measures such as forming microscopic rugged parts on the almost C-shaped surface 5 or sticking a reflector capable of scattering light may be taken. In addition, when the combination of the emitter 3 and the light guiding body 4 is used, an almost cylindrical body 7 capable of holding the light guiding body 4 such as a transparent cylinder or an opaque cylinder having a notch 6 for exposure is provided, and such almost cylindrical body 7 may be fixed to a surface 9 to be mounted such as a bedside or a wall surface by a fixing means such as a screw 8. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device capable of selecting two kinds of lighting applications.

[0002]

2. Description of the Related Art The use of a light emitting device having a light source such as a light emitting diode is known to be used for direct light and for controlling light from a light source through a light guide.

[0003]

[Problems to be Solved by the Invention] However, no proposal has been made yet to selectively utilize both of them. The present invention has been made in view of such problems to be solved, and an object thereof is to provide a lighting device capable of selecting two types of lighting applications.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described, but it is merely an exemplary embodiment adopted based on the present invention, and the present invention is based on matters peculiar to the embodiment. However, the technical scope of the present invention should be determined based on the matters shown in the claims and the matters substantially equivalent to the matters.

In the illustrated embodiment, a light-emitting body 3 having a cylindrical body 2 having one end opening having a light source 1 such as a light-emitting diode therein, and a light-emitting body 3 which can be inserted into the opening of the cylindrical body 2 of the light-source 1 at the time of insertion. The use of direct light from the light emitting body 3 provided with a light guide body 4 capable of emitting light to the outside after introducing the light (see FIG. 2).
And a combination of the light emitter 3 and the light guide 4 (see FIG. 1). The light guide 4 has a substantially C-shaped cross section so that the light introduced from the end can be emitted from the side surface, and the substantially C surface 5 has a light scattering reflection function. For example, well-known means such as forming fine irregularities on the substantially C surface 5 or attaching a reflecting material capable of scattering light may be arbitrarily implemented. In addition, the luminous body 3
When used in combination with the light guide 4, a substantially cylindrical body 7 such as a transparent cylinder capable of holding the light guide 4 and an opaque cylinder having a notch 6 for exposure is provided. It is advisable to fix 7 to a mounting surface 9 such as a bedside or a wall surface by a fixing means such as a screw 8.

Further, it is preferable that the light emitting body 3 is provided with a reflecting mirror 10 such as a paraboloid surrounding the light source 1. The light guide 4 is formed of a transparent acrylic resin, etc., and an elastic body 12 such as rubber is wound around the outer periphery of the medium diameter portion 11 near the base portion. When the medium diameter portion 11 is pushed into the opening of the tubular body 2, the light guiding body 4 is guided. The body 4 is inserted and fixed in the tubular body 2. Then, at the time of insertion and fixing, the inner end of the small-diameter portion 13 of the base is brought close to the light source 1 to introduce light into the light guide 4. The introduced light is emitted in the side direction by the light scattering reflection function of the substantially C surface 5 as shown by the dotted line in FIG.

When the light emitting body 3 and the light guiding body 4 are used in combination as shown in FIG. 1, it is clear from the above description.
When using the direct light of the light emitting body 3, the light guide 4 may be removed from the light emitting body 3. Further, in order to use it as a desk lamp, the light emitting body 3 may be supported by the arm device 14 or the like as shown in FIG.

Thus, it is possible to provide a lighting device which can select two kinds of lighting applications.
