For example, Japanese Patent Application Laid-Open No. 4-192202 proposes a small guide lamp using an FL in which the aspect ratio of the display panel is 1: 1. If it is small and can perform the same function as a guide light, it will be a great advantage in terms of scenery, and it will have high utility value for customer service facilities such as department stores.

[0003]

By the way, there are cases where it is desired to install this type of guide light not only on the ceiling surface but also on the wall surface depending on the installation location. However, conventional ones are not limited to those with an aspect ratio of 1: 3 or 1: 5, and even those with a 1: 1 aspect ratio are designed to be mounted on the ceiling surface. , A special mounting bracket such as an L-shaped bracket having a support portion extended to the upper part of the guide lamp is used, and the guide lamp newly designed for mounting on a wall is used, which lacks versatility.

[0004]

According to a first aspect of the present invention, a display panel having an aspect ratio of 1: 1 and a vertical orientation, and an opening for mounting the display panel have an aspect ratio of 1: 1. Lamp body formed in the shape of a rectangular frame and having a built-in light source, a mounting portion fixed to one side of the lamp outer surface and mounted on a ceiling surface or a wall surface, and a mounting direction of the display panel with respect to the lamp body is 90 degrees. It is composed of a panel holding portion which is freely rotatable in each direction.

In the second aspect of the invention, the aspect ratio is 1: 1.

It is configured by an attachment portion fixed to one side of the outer surface of the lamp body and attached to a ceiling surface or a wall surface.

In the invention according to claim 4, the aspect ratio is 1: 1.
The display panel having the vertical direction and the light diffusion property, the cylindrical body having the rectangular frame shape with the aspect ratio of 1: 1 having the opening for mounting the display panel, and the light source having the vertical direction are provided. A base body having an attached base portion and rotatable in two directions rotated 90 degrees in the cylinder body; a mounting portion fixed to one side of the outer surface of the cylinder body to be mounted on a ceiling surface or a wall surface; The display panel should be attached to the body at 90
It is composed of a panel holding part which can be freely rotated in each direction.

[0008]

In the case of the guide light having the display panel with the aspect ratio of 1: 3 or 1: 5, the installation is limited to the horizontally long state in consideration of its display directivity. Therefore, it may be installed on the ceiling surface or the wall surface. Therefore, it is difficult to have commonality. However, in the case of a guide light having a display panel with an aspect ratio of 1: 1, if display directionality of the display panel can be secured,
There is no problem even if the guide light main body is rotated 90 degrees, and the mounting on the ceiling surface and the mounting on the wall surface can have commonality.

Therefore, according to the invention of claim 1,
Since the display panel with an aspect ratio of 1: 1 can be attached to the lamp body by the panel holding portion so that the mounting direction can be freely rotated 90 degrees, it is displayed according to whether the lamp body is mounted on the ceiling surface or the wall surface by the mounting portion. It suffices to mount the panel in consideration of the directionality of the panel, and there is no mounting directionality for the ceiling surface and the wall surface without using a separate mounting bracket or the like.

In the second aspect of the invention as well, the light diffusing panel is provided on the back surface of the display panel, so that there is no mounting directionality and a display with uniform brightness can be obtained.

In particular, according to the third aspect of the invention, since the display panel and the light diffusing panel can be integrally mounted on the lamp body by the frame body, the mountability is good.

Further, in the invention according to claim 4,
Even if the light source itself has a vertical orientation due to the relationship with the display panel, the orientation of the light source is not limited to the orientation of the display panel depending on whether the cylinder is attached to the ceiling surface or the wall surface. Since it can be selected depending on the base body, it is possible to secure a display state with more uniform brightness regardless of whether it is attached to the ceiling surface or the wall surface. In particular, when the display panel is provided with a light diffusing property corresponding to the shape of the light source so that the shadow of the light source is not reflected, its directionality can always be maintained and the light diffusing property can be utilized to the maximum extent.
