DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotating warning light,
More specifically, the present invention relates to a structure of a rotation warning light capable of arbitrarily changing the angle of the rotation light constituting the rotation warning light.

[0002]

2. Description of the Related Art In recent years, a rotation warning light has been used as a means for notifying an abnormality of a process in a factory or the like, and to draw attention at an entrance or exit of a company or a parking lot, a factory site, or a gas station. Widely used as a means.

[0003] The structure of a generally used rotating warning light includes a light source, a rotating mirror provided to be rotatable around the light source in a fixed direction, and a globe surrounding the light source and the rotating mirror. The rotating lamp has a structure attached to a predetermined base.

Therefore, when the rotation warning light is mounted at a predetermined position, the plane of light formed by the light emitted from the light source reflected by the rotating mirror is along a plane in a certain direction. Therefore, in order to change the plane of the light formed by the light emitted from the light source, it is necessary to change the mounting of the rotation warning light itself or to use a plurality of rotation warning lights. Therefore, for example, when it is necessary to frequently change the direction of the plane formed by the light source, it is necessary to frequently change the position of the rotation warning light, which is very troublesome.

[0005] The present invention has been made to solve the above problems, and an object of the present invention is to provide a rotation warning lamp capable of easily changing the plane of light formed by a light source.

[0006]

According to a first aspect of the present invention, there is provided a rotating warning lamp according to the first aspect, comprising: a light source;
A rotating mirror provided so as to be rotatable around the light source in a fixed direction, a rotating light including a globe surrounding the light source and the rotating mirror, and a base supporting the rotating light, further comprising a base The first base and the second base are defined by a plane having a normal line where an angle between the rotation mirror and the rotation axis is an acute angle.
And the rotating light is fixed to the first base, and the second base is
It is supported rotatably along the plane.

According to a second aspect of the present invention, there is provided a rotation warning light according to the first aspect, wherein the base has a cylindrical shape, and a rotation axis of the rotating mirror is the base. And the base is divided into a first base and a second base by a plane having a normal with an angle of 45 ° with the axis.

According to the first aspect of the present invention, the rotating warning lamp is supported by the base, and the base has a normal line at which the angle between the rotating lamp and the rotation axis is acute. It is divided into a first base and a second base by a plane.

Therefore, even when the second base is fixed to the predetermined substrate, the first base rotates along the plane, and the light generated by the light emitted from the light source inside the rotary lamp is accordingly formed. Can be gradually changed. In addition, since this plane has a normal that forms an acute angle with the rotation axis of the rotating mirror, the trajectory of the light source of the rotating lamp varies in a substantially spiral shape with respect to the plane of the first base. By drawing a plane at an appropriate angle, it becomes possible to sufficiently attract the viewer's attention.

Therefore, it is possible to easily change the angle of the plane of the light formed by the light source without moving the rotation warning lamp itself as in the related art.

According to a second aspect of the present invention, there is provided a rotation warning lamp according to the first aspect, wherein the outer shape of the base is further cylindrical, and the base has a cylindrical shape. The base is divided into a first base and a second base by a plane having a normal line at an angle of 45 ° with the axis of the shape.

Therefore, when the first base is rotated by 180 ° with respect to the second base from the state where the first base and the second base form a cylindrical shape, for example, when the second base is fixed to a horizontal plane, The plane of light formed by the light source from the horizontal to the vertical
0 ° can be changed.

Further, according to the above-mentioned shape, it is possible to set the shape between the first base and the second base to a shape that is interesting from the viewpoint of interior as well as to an arbitrary angle.
