  In the above invention, the irradiation object is a book, which is a book end composed of the lighting device (invention of claim 5).

  According to the present invention, it is possible to provide an illuminating device that takes advantage of the technical features of the LED plate. For example, by combining a book end against which a book or the like is leaned with an LED plate, information on the back cover of the book or the like It is possible to provide an illumination device that can be easily viewed and searched.

The perspective view of the left book end as an illuminating device which concerns on this invention, A perspective view of the book end on the right, Front view of the bookend on the left, FIG. 3 is a cross-sectional view taken along the line AA shown in FIG. FIG. 3 is a cross-sectional view taken along the line BB shown in FIG. Detailed cross-sectional view of the light source section of the bookend on the left, Use state explanatory drawing of the lighting device, The perspective view of the center book end as an illuminating device which concerns on this invention, Front view of the bookend, FIG. 9 is a cross-sectional view taken along line AA shown in FIG. FIG. 9 is a cross-sectional view taken along the line BB in FIG. It is use condition explanatory drawing of the illumination device.

Embodiments of a lighting device according to the present invention will be described with reference to the drawings.
The lighting device according to the embodiment shown in FIGS. 1 and 2 includes left and right book ends 1 and 2 for stably standing a book B as an irradiation object, and includes a main body 3 and 4 and legs 5 and 6, respectively. It is configured in a substantially L shape.
Since the left and right book ends 1 and 2 are substantially the same, the same reference numerals are given, and the left book end 1 is represented by the right book end 2.

As shown in FIG. 1, a main body 3 of a left book end (hereinafter simply referred to as a book end) 1 includes an arc-shaped side, a vertical side W2, and a depth side W3 as a horizontal side W1, and the vertical side W2 and depth. The side surface 30 constituted by the side W3 is provided with an LED plate as the light source unit 7 arranged along the vertical side W2 and adjacent to the arcuate side W1.
When the book B is juxtaposed in parallel with the side surface 30, the LED plate 7 is at a position X intersecting the back surface B1 constituted by the horizontal side w1 and the vertical side w2 of the book B, and on the back surface B1. It is arranged to face.

That is, the size of the arc-shaped side W1 and the vertical side W2 of the main body 3 is substantially the same as that of the book B for the book B composed of the horizontal side w1, the vertical side w2, and the depth side w3. The size is larger than that of the book B, and the LED plate 7 is provided on the side surface 30 of the excess width W4 that exceeds the size. The LED plate 7 faces the spine as the back surface B1 of the book B at a substantially right angle, and the LED plate 7 faces the back surface B1 with the back surface B1 and the LED plate 7 intersecting. .
The light emitted from the LED plate 7 irradiates the spine B1 of the book B.

  The main body 3 is formed with an image that is shared with the outer shape of the book B, and the arc-shaped side W1 is formed in a round shape like the spine of the book B, and the heel also shines. It has a configuration like “Book”.

A concave portion 31 (see FIGS. 4 and 6) for attaching the LED plate 7 is formed on the side surface 30 of the main body 3, and the plate 7 is attached thereto with a double-sided tape, an adhesive, or the like.
Since the LED plate 7 is thin (for example, about 3 millimeters in thickness), the LED plate 7 may be attached to the main body 3 without providing the recess 31.
As shown in FIGS. 4 and 5, a space portion 32 is provided inside the main body 3, and a power supply portion such as a storage battery, a control portion for controlling the power supply portion, and the like are accommodated therein.

The foot 5 has a book B placed thereon and stably supports the main body 3 and is attached to a bottom surface 33 constituted by the arc side W1 and the depth side W3. It is extended to one end side.
The space portion 32 is opened on the bottom surface 33 side, and the foot 5 and a cover (not shown) serve as a lid for the space portion 32.

  The LED plate 7 is configured by directly mounting an LED bare chip on the substrate 70. More specifically, the bare plate 71 is connected to a wiring pattern (not shown) of the substrate 70, as shown in FIG. As described above, a lens-shaped coating layer 72 is formed on the bare chip 71.

  The switch for controlling the on / off of the LED plate 7 is not shown, but is disposed on the back side 34 formed by, for example, the arc side W1 and the vertical side W2 or the upper side of the depth side W3. It can also be a touch switch.

An example of using the bookend configured as described above will be described.
As shown in FIG. 7, the book B is leaned between the left and right book ends 1 and 2 and the LED plate 7 is turned on for use.

The operational effects of the lighting device configured as described above are as follows.
1. Since the light emitted from the LED plate 7 is configured to be diffused, it is uniformly incident on the entire spine B1 of the book B, and is reflected by the spine B1 according to the law of reflection.
That is, the light generated by the LED has a characteristic that directivity is good,
Since the lens-like coating layer 72 is provided to diffuse light, the light enters the back cover B1 of each book B.
As a result, it is possible to recognize the information on the spine cover B1 so that it is easy to see and search information on the spine cover of books and the like.
2. The LED plates 7 and 7 of the left and right bookends 1 and 2 are in opposing positions, and the emitted light interferes with each other, and light intensity can be formed.
Therefore, each spine cover B1 of each book B can be illuminated brightly, and information such as a spine cover of the book can be easily viewed and searched.
3. The main body 3 is formed so as to be in common with the outer shape of the book B, and the bag has a structure like a “shining book”.
4). Since the LED plate 7 is thin, it can be directly attached to the main body 3 and can be easily manufactured as a lighting device.
5. The bookends 1 and 2 can be placed on a desk and used as a book stand, as well as a desk lamp.

In the above embodiment, the book end is configured to lean against a book. However, the lighting device according to the present invention is not limited to this. The lighting device uses a CD case as a lighting object, and the product display shelf uses a product. It is good also as an illuminating device.
In such a case, it is good also as an illuminating device of an external shape so that it may match with an illumination target object.
Moreover, you may use for the illuminating device for showcases arrange | positioned at the shop front etc. of a bookstore.

Next, a configuration example of another example book end 1A will be described with reference to FIGS.
The configuration common to the book end 1A and the book end 1 will be denoted by the same reference numerals and the description thereof will be omitted, and a configuration in which both are different will be described.

As shown in FIGS. 8 to 11, the main body 3A of the book end 1A has left and right side surfaces 30A and 30A constituted by the vertical side W2 and the depth side W3 along the vertical side W2, and The left and right LED plates 7 are disposed adjacent to the arcuate side W1.
The legs 8 attached to the bottom surface 33 constituted by the arc side W1 and the depth side W3 extend outward from both ends of the side surfaces 30A and 30A.

With such a configuration, the book end 1A has a substantially inverted T shape with the main body 3A and the foot 8, and is used as follows.
The book B is leaned on the left and right sides of the book end 1A, and the LED plates 7 and 7 are lit.
When the amount of the book B is large, as shown in FIG.
Other configurations are the same as those of the above-described embodiment, and have the same effects.

  The present invention is not limited to the embodiments described above, and many variations can be made by those having ordinary knowledge in the art within the technical idea of the present invention.
