  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated, referring attached drawing.

[Lighting Device According to Embodiment 1 of the Present Invention]
1A and 1B are schematic perspective views of a lighting apparatus according to Embodiment 1 of the present invention, in which FIG. 1A shows a state during use, and FIG. 1B shows a state when not in use.

  As shown in FIG. 1, the lighting device according to Embodiment 1 of the present invention is a lighting device including a base 30 and a plurality of light emitting devices 20 attached in the length direction of the base 30. The base 30 is a belt-like member having flexibility, and is suspended in a spiral shape with one end in the length direction located inside the spiral or the other end in the length direction located outside the spiral as a fulcrum. It is a lighting device. Note that FIG. 1 shows an example in which the base 30 is hung in a spiral shape with one end 32 in the length direction located inside the helix as a fulcrum.

  Hereinafter, it demonstrates in order.

(Light Emitting Device 20)
The plurality of light emitting devices 20 are attached in the length direction of the base 30. The interval (pitch) X along the base 30 to which the plurality of light emitting devices 20 are attached may be uniform or non-uniform. However, if it is uniform, the surroundings can be illuminated evenly. Although the space | interval (pitch) X along the base 30 is not specifically limited, As an example, 9.2 mm etc. can be mentioned.

  For the light emitting device 20, a light emitting diode, a light emitting diode chip, or the like can be used. The light emitting diode is packaged, and the light emitting diode chip is not packaged.

  The plurality of light emitting devices 20 may be directly attached to the base 30, but may be attached to the base 30 using the substrate 10. In this case, the plurality of light emitting devices 20 are mounted in the length direction of the substrate 10.

  A flexible member is used for the substrate 10. Examples of the member having flexibility include a flexible flat cable (FFC) and a flexible substrate (FPC).

  A strip-shaped member is used for the substrate 10. As an example of the band-shaped member, a member having a thickness of 0.1 mm, a width of 15 mm, and a length of 1100 mm can be given. In FIG. 1 (a), the width of the substrate 10 seems to be different in the length direction of the substrate 10. This is because FIG. 1 is a perspective view. In Embodiment 1 of the present invention, the width of the substrate 10 is uniform in the length direction of the substrate 10.

  The substrate 10 is attached to the base 30 using an adhesive or a double-sided tape.

(Base 30)
A member having flexibility is used for the base 30. As an example of the member having flexibility, a resinous molded product such as ABS resin and a metal product cut with a punching die can be cited. Due to the flexibility of the base 30, when the base 30 is suspended, the plurality of light emitting devices 20 attached to the base 30 are separated from each other, and buffering of the plurality of light emitting devices 20 is suppressed (FIG. 1 ( a)).

  For the base 30, a band-shaped member having a front surface and a back surface is used. As an example of the band-shaped member, a member having a thickness of 1 mm, a width of 20 mm, and a length of 1300 mm can be given. In FIG. 1A, the width Z of the base 30 seems to be different in the length direction of the base 30, and this is because FIG. 1 is a perspective view. In Embodiment 1 of the present invention, the width Z of the base 30 is equal in the length direction of the base 30.

  The base 30 is, for example, arranged so that its front surface 30a faces the outside of the helix and its back surface 30b faces the inside of the helix, or its front surface 30a faces the upper side of the helix, and its back surface 30b faces the lower side of the helix. It can be arranged so that it faces. However, as shown in FIG. 1, when the base 30 is arranged so that the front surface 30a faces the outside of the spiral and the back surface 30b faces the inside of the spiral, the lighting device is not made bulky in the lateral direction. It can be downsized.

  The substrate 10 is attached to the front surface 30a and the back surface 30b of the base 30, for example. However, when attached to the front surface 30a of the base 30, the periphery of the lighting device can be illuminated more easily than when attached to the back surface 30b of the base 30.

  The base 30 is suspended in a spiral shape with one end 32 in the longitudinal direction positioned inside the spiral or the other end 34 in the longitudinal direction positioned outside the spiral as a fulcrum. That is, one end 32 and the other end 34 in the length direction of the base 30 are respectively located on the inner side or the outer side of the spiral, and one of them is used as a fulcrum for suspension.

  However, since the radius of the helix becomes larger toward the outside of the helix, the base 30 has a higher spring constant in the vertical direction in the portion located inside the helix than the portion located outside the helix. It has the property that it is difficult to stretch. On the other hand, the gravity due to the weight of the base 30 itself is smaller for the part closer to the fulcrum located above than for the part farther than the fulcrum located below, so the base 30 is closer to the part closer to the fulcrum. It has the property that it is easier to extend in the vertical direction than the portion farther from the fulcrum. Therefore, when the base 30 is suspended with the longitudinal end 32 positioned inside the helix as a fulcrum, the height of the spring constant and the magnitude of gravity work in a direction that cancels out the difference in ease of extension in the vertical direction. In other words, the difference in the distance Y between the plurality of light emitting devices 20 in the vertical direction is smaller than when the base 30 is hung from the other end 34 in the length direction positioned outside the spiral.

  The base 30 is wound spirally when not in use. Thereby, a lighting device can be stored compactly when not in use. That is, the thickness of the lighting device when housed is the width Z of the base 30 in the length direction, and can be very small. In addition, when the base 30 is suspended in a spiral shape with the end 32 in the length direction positioned inside the spiral as a fulcrum (see FIG. 1A), the length direction one end 32 positioned inside the spiral. Is taken up with the inside (see FIG. 1B).

  As described above, according to the first embodiment of the present invention, the versatile lighting device that can be used for various purposes without being light and bulky by the base 30 using the strip-shaped member having flexibility. Can be provided. Therefore, according to Embodiment 1 of the present invention, it is possible to easily use the lighting apparatus not only indoors but also outdoors such as a restaurant eaves or a construction site on a road.

  In addition, according to the first embodiment of the present invention, the lighting device can be compactly stored when not in use, so that it can be used not only indoors but also outdoors such as on the eaves of restaurants and on construction roads. It becomes possible to use the lighting device easily.

  In addition, according to Embodiment 1 of the present invention, an illumination device that is long in the lengthwise direction can be configured, so that it has a large light emitting area when in use, but is not spirally wound up when not in use. The device can be realized, and it is possible to provide a lighting device that is larger than a conventional lighting device and can illuminate a wide area only when in use.
