Description

  The present invention relates to an illuminating device installed on a desk or the like, and more particularly to an illuminating device capable of selecting an illumination light irradiation range by a simple operation.

  Conventionally, for reading on the desk and various work on the work table, in addition to room lights, stand-type lighting fixtures are used to locally illuminate to ensure a lighting environment with a predetermined brightness. Thus, the visibility of the object is enhanced so that various operations can be easily performed.

  As such lighting fixtures, for example, on a desk top surface, a spotlight directly attached in a state where it can be swung at a certain angle, a flexible light bent into a square shape, etc. are known, If such a lighting fixture is used, illumination light can be concentrated and projected toward a desired site.

  As an example of the above-mentioned lighting fixture, there exists a lighting fixture of patent document 1, for example. This luminaire includes a main body, an arm connected to the main body via a lower connecting portion, and a lamp portion connected to the arm via an upper connecting portion, and the arm is horizontal to the main body. Since the main body can be rotated in the direction and the vertical direction, the degree of freedom in selecting the illumination range can be ensured even if the main body does not rotate with respect to the installation surface.

Moreover, the protrusion part 105 is provided inside each side part 103 so that it may oppose. The protruding portion 105 is configured to abut the other end of the second arm 60 when the swinging portion 100 is swung vertically with the other end of the second arm 60 as a fulcrum. The movable range of the swing of the second arm 60 can be limited by the contact.

The sandwiching body 101 sandwiches the other end portion of the second arm 60 with each side surface portion 103.
The other end of the second arm 60 is disposed in the holding body 101, and the second arm 60 is inserted through the through hole 61 of the other end of the second arm 60 from the through hole 103a. The sandwiching body 101 can be fixed so that the head can be swung.

  The rotation unit 200 is provided on the bottom side of the sandwiching body 101, and includes an arm-side stopper 201, a rotating shaft 202, and an illumination-side stopper 203. The arm-side stopper 201 and the rotating shaft 202 are connected to the bottom 102 side of the sandwiching body 101, and a connecting blanket 83 constituting the illumination unit 80 is rotatably connected to the rotating shaft 202. Thereby, the illumination unit 80 main body can rotate around the axis of the second arm 60. The illumination side stopper 203 is fixed to the connection blanket 83. Then, the rotary shaft 202 is rotatably connected to the connection blanket 83 while being inserted into the illumination side stopper 203 through the washer 204. Thereby, the illumination unit 80 main body can be rotated around the axis of the second arm 60.

Next, the configuration of the rotating unit will be described in detail with reference to FIG.
FIG. 3A is a diagram showing the configuration of the arm-side stopper 201, and FIG. 3B is a diagram showing the configuration of the illumination-side stopper 203.
As shown in FIG. 3A, the arm-side stopper 201 is continuously provided integrally with the rotary shaft 202 on the back side of the bottom 102 of the sandwiching body 101 as described above. The arm-side stopper 201 is a flat plate-like member and has a protruding piece 201a having a polygonal shape and one side protruding. On the other hand, the illumination-side stopper 203 has a flat plate shape, has a rising piece 203a at the end, and has a through hole 203b in the approximate center. The illumination side stopper 203 is fixed to the connection blanket 83 with a screw or the like.
Note that the height of the rising piece 203a of the illumination side stopper 203 is substantially the same as the thickness of the protruding piece 201a of the arm side stopper 201. The arm-side stopper 201 and the illumination-side stopper 203 are assembled so as to overlap on the same axis. Accordingly, the rising piece 203a can come into contact with the protruding piece 201a when the illumination side stopper 203 is rotated.

Next, with reference to FIGS. 4A to 4D, the operation of the illumination unit using the rotating unit will be described.
4A is a diagram showing a state in which the illumination unit is facing downward, and FIG. 4B is a diagram showing a state in which the illumination unit is facing left, and FIG.

  As shown in FIG. 4C, the illumination unit 80 can be rotated 90 ° counterclockwise to change the illumination direction to the right. And as shown in FIG.4 (d), when the illumination part 80 is rotated 180 degrees counterclockwise from the state of Fig.4 (a), it will be in an upward state. In such a case, for example, since the ceiling of the room can be illuminated, the illumination device 1 can be used as indirect illumination. When the illumination unit 80 rotates 180 ° counterclockwise, the illumination side stopper 203 also rotates 180 ° counterclockwise, and the rising piece 203a contacts the protruding piece 201a of the arm side stopper 201. Thereby, it can restrict | limit that the illumination part 80 rotates 180 degrees or more counterclockwise.

Next, how the lighting device is used will be described.
FIGS. 5A to 5D are views showing examples of usage modes when the lighting device is installed on a desk.
As shown in FIG. 5A, the first arm 40 is held so as to be substantially perpendicular to the operation unit 20, and the second arm 60 is bent upward so that the first arm 40 is bent. And the illumination part 80 can be made into a high position by making it the 2nd arm 60 on a substantially straight line. And the ceiling part can be illuminated by directing the illumination part 80 upward by the swing mechanism 70, for example, it can be used as a night light.

  Further, as shown in FIG. 5B, the lighting device 1 is transported by bending the second arm 60 downward with the second connecting portion 50 as a fulcrum so as to be substantially parallel to the first arm 40. It can be made compact when storing and storing.

  Further, as shown in FIG. 5C, the lighting unit 80 is positioned under the desk by bending the first arm 40 with the first connecting unit 30 as a fulcrum so as to be substantially parallel to the installation surface. To do. Thereby, even the lighting device 1 installed on the desk can illuminate under the desk, and even when an object is dropped under the desk, the lighting device 1 can illuminate, so that the discovery can be accelerated.

  Further, as shown in FIG. 5 (d), the first arm 40 is bent forward at a predetermined angle with the first connecting portion 30 as a fulcrum, and the second arm 60 is supported with the second connecting portion 50 as a fulcrum. Bend downwards. Next, when the illumination unit 80 is rotated 180 ° counterclockwise, the illumination unit 80 facing upward is located at the user's hand. In such a case, when the user works at hand, the hand can be brightened, which is useful, for example, for viewing a photographic negative or stamp.
