Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a desk lamp, and particularly to a desk lamp that is most suitable for being placed on the floor.

[Prior art]

Desk lamps, especially so-called floor stands placed on the floor, have been commercialized in various shapes. Most of them have a configuration as shown in FIG. 1, for example. In other words, the base plate 1 placed on the floor etc.
00, a support 101 that extends vertically upward, and a shade 103 that covers the light source 102 at the upper end of this support 101. In a stand with such a configuration, the direction of illumination can be changed by tilting the shade 103, but it only illuminates the floor around the stand. It was not possible to change it at will.

Also, the one described in Japanese Utility Model Publication No. 12-5666 has basically the same structure as the one shown in Figure 1, but a ring is attached to the lampshade (globe), and the shade is tilted with respect to this ring. It was installed as possible. In the tilting means, one end of the continuous piece is rotatably attached to the ring body, the other end of the continuous piece is connected to the shade, an elastic clamping mechanism is attached to the ring body at a position opposite to this continuous piece, and the shade is attached to the mechanism. The shade is tilted by the length of the lifting rod. Therefore, the light cannot be distributed within the tilt range of the shade (up to an inclination of 45 degrees at most), and if the top and bottom ends of the shade are open, the downward light distribution will be diagonally downward. If so, the upward light distribution is coaxial with this ray and diagonally upward,
It has been impossible to distribute light in many different ways, such as only upwardly, only on one side, only on both sides, only downwardly, etc.

〔the purpose〕

The present invention has been made in view of the above-mentioned conventional circumstances, and an object of the present invention is to provide a desk lamp that can change the lighting direction or lighting mode in various ways.

〔composition〕

In order to achieve the above object, the present invention includes a base;
A support that is attached to the base, two support members that are spaced apart from each other at the upper end of the support, a light source that is provided between the support members, and a box that is open on at least one side that covers the light source. , at least two pieces are attached in pairs on both sides of the light source so as to be rotatable and fixable at a desired rotational position between the supporting members;
It consists of a cover whose inner surface is a reflective surface.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 2 shows a perspective view of a desk lamp 10 which is an embodiment of the present invention. The desk lamp 10 includes a triangular prism-shaped base 1 placed so that both sides are triangular, a support 2 integrally fixed to the upper end of the base 1, and a light source provided on the top of the support 2. ,
It is composed of covers 3 and 4 that cover the light source.
The support column 2 is a long plate-like member, and has upper side parts 20,
21 extends upward, and short cylindrical support members 5, 5' are fixed to the upper ends of both side parts 20, 21, respectively. Although various members are attached to the support members 5 and 5', the configuration on the support member 5' side is the same as the configuration on the support member 5 side, so the support member 5 side will be described below as an example. Explain. Support member 5
is opened inward, and a cylindrical fixing portion 50 is formed on the inner surface thereof. and a cover 3 attached between the fixed part 50 and the fixed part on the supporting member 5'side;
4 is a structure in which the bases of two right-angled triangular plates are integrally connected by a square plate, and a circular plate 30 having a diameter equal to or slightly smaller than the support members 5 and 5' is attached to the right-angled portion corresponding to the apex of the triangle. and 40 are fixed. As shown in FIG.
0 is adjacent to the fixed part 50, the disc 40 of the cover 4 is adjacent to this disc 30, and the rotary washer 6 is fitted into the insertion holes 31, 41 formed at the center of the discs 30 and 40. . The rotary washer 6 has a collar portion 60
and a shaft portion 61, into which the disks 30, 40 of the covers 3, 4 are rotatably fitted,
The rotary washer 6 is fixed to the fixed part 50 with a screw 62. Note that a spacer 32 is fixed around the insertion hole 31 of the disc 30, and the disc 30 and the disc 4 are
The distance from 0 is kept constant. Further, a corrugated washer is interposed between the collar portion 60 of the rotary washer 6 and the disc 40 of the cover 4, and the disc 30 of the covers 3, 4,
40 to the fixed part 50.
Therefore, the discs 30 and 40 are in close contact with each other, and the covers 3 and 4 are configured not to rotate unless a rotational force is applied from the outside. Furthermore, on the inner surface of the disc 40 of the cover 4,
A mounting member 42 having an L-shaped cross section is fixed, and a lamp 7 serving as a light source and a reflecting plate 8 are mounted to this mounting member 42. The lamp 7 is attached to one side of a disk 70 having a diameter equal to or slightly smaller than the disks 30, 40 of the covers 3, 4, and the other side of the disk 70 has a lamp as shown in FIG. A locking member 71 fixed to the mounting member 42 of the cover 4 with a screw or the like.
However, it is fixed. The end of the locking member 71 extends from the peripheral edge of the disk 70 toward the lamp 7 , and a reflecting plate 8 having an arcuate cross section that covers the lamp 7 is attached to this extended portion.
is fixed. The reflector plate 8 is installed so as to face the cover 4 with the lamp 7 in between, and prevents the light from the lamp 7 from directly irradiating the outside.
It is designed to provide indirect light that is reflected by the surrounding area.

In addition, the discs of the covers 3 and 4 on the support member 5' side are
A disc of the cover 3 is located inside the cover 4, and a lamp and a reflector are attached to the disc of the cover 3. Note that the other configurations are the same as the configuration shown in FIG. 3.

Next, the function of the desk lamp 10 will be explained. As can be seen from the above configuration, the desk lamp 1
The covers 3 and 4 of No. 0 can be freely rotated by external operation and can also be fixed in that position, so that the positions of the covers 3 and 4 can be changed in various ways. . It is therefore possible to provide a number of illumination configurations by varying the position of the covers 3, 4, as shown for example in FIGS. 5a to 5f. Further, the light from the lamp is not directly irradiated to the outside, but is reflected by the covers 3 and 4 as indirect illumination, so that a soft illumination effect can be provided.

In the above embodiment, the side shapes of the covers 3 and 4 are right triangles, but other shapes may be used.

〔effect〕

As explained above, according to the present invention, the two pairs of covers provided at least on both sides of the light source that cover the light source are configured to be rotatable and fixable at a desired rotational position, so that the position of the cover can be controlled. Since it can be varied in various ways, it is possible to provide a wide variety of illumination forms that were not available before. Therefore, it not only has the functionality of being able to change the lighting direction, but also
It can also be used as part of interior decoration.

Furthermore, by changing the opening surface of the box-shaped cover, or by having two or more opening surfaces, various types of light distribution are possible. moreover,
Since the inner surface of the cover is a reflective surface, various types of reflected light can be obtained in addition to direct light depending on the box shape of the cover.

In addition, in the case where the light source is provided with a reflector, all the light from the light source is reflected by the cover, and indirect illumination can be achieved using the cover as a medium, and soft light quality can be provided.
