Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a display/lighting device that has a convenient curved shape, particularly for use on utility poles.

[Prior Art] Conventional display/lighting equipment includes billboards, advertising billboards, and the like. Among the signboards, there are many that are illuminated by a light source or the like provided inside. However, all of them are installed on flat areas or are used as stand types.
Also, when the surface area to be irradiated becomes larger, several places (several lines)
Providing a light source increases illuminance unevenness and increases cost.

In addition, some display and lighting equipment that can be attached to telephone poles is made by bending sheet metal into a cylindrical curved surface, but this is of no use at night.

Generally speaking, as an improvement on this, there is a method that uses light from outside to illuminate the screen, but in this case too, the illuminance is highly uneven and the view is not good.

[Problems to be Solved by the Invention] The present invention can be installed in a place that is not flat but has a cylindrical shape, specifically, a utility pole or the corner of a building.1. The purpose of the present invention is to provide display/lighting equipment that requires low maintenance costs.

[Means for Solving the Problems 1] The present invention provides a display/lighting device in which a display is formed on the surface of an exterior body, which includes: a surface of the exterior body having a curvature; a base plate having a curvature for holding the exterior body; , a sheet-shaped sheet in which a linear light source located between the exterior body and the base plate for illuminating the exterior body, and microprisms provided on the inner surfaces of the exterior body and the base plate are continuously formed on the surface; It has a structure characterized by being made of a transparent member.

[Example] FIG. 1 shows a display/lighting device 13 according to the present invention installed on a utility pole 6.
FIG. 2 is a cross-sectional view of an embodiment of the device mounted on the device, viewed from above.

The base plate 1 made of sheet metal is painted white or has a mirror surface in order to improve the reflectance of light, and on top of that is a linear light source 2 (in this case, a fluorescent lamp) and a reflective plate near the linear light source 2. 3 and a reflecting plate 4 is provided on the opposite side from the linear light source 2. In addition, Shinko iF! The reflective plate 4 provided on the opposite side to 2 may be omitted.
Another linear light source may be provided in place of the reflecting plate 4.

In addition, on the inner surface of the base plate 1 (the surface not facing the utility pole 6-), a large number of microprisms are arranged side by side on the front surface as shown in FIGS. Part 7
is attached with the prism surface 8 facing the telephone pole 6 (
(See Figure 4). An exterior body 5 made of a light diffusing material is fixed onto the base plate 1 so as to cover these. Further, a sheet-like transparent member 7 provided with microprisms is attached to the inside of the exterior body 5 with the prism surface 8 facing the exterior body 5. An arbitrary display is provided on the outside of the exterior body 5 using known means such as paint or a sheet.

FIG. 2 is a front view of the display/illumination fixture 13 mounted on the utility pole 6. Ballast 10 for line light source 2
etc. are provided inside the exterior body 5.

Next, the operation of the above embodiment will be described.

As shown in FIG. 6, the light emitted from the linear light source 2 (fluorescent lamp) is transmitted to the flat surface of a sheet-like transparent member 7 having a prism surface 8 pasted on the base plate 1 and on the inner surface of the exterior body 5. 11, some of it leaks out as it is, and the rest of it is reflected one after another, so that the light reaches the inside of the device uniformly. In this case, the sheet-like transparent member 7 is attached so that the ridge line of the apex angle of the prism is approximately perpendicular to the longitudinal direction of the linear light source 2, and the sheet-like transparent member 7 suppresses uneven illuminance to a small level. be able to.

Therefore, the linear light source 2 only needs to be provided at one location, or at most two locations, which reduces costs and maintenance costs.

In the above embodiments, the linear light source is not limited to a linear fluorescent lamp, but may also be a linear arrangement of point rays of natural light.

The telephone pole 6 usually does not have a uniform thickness, but has a certain taper, and becomes thinner toward the top. Therefore, when attaching the display/lighting equipment to such a telephone pole 6, as shown in Fig. 7, a spacer 12 such as rubber is inserted between the narrow part and the equipment to adjust the level. do.

FIG. 8 is a sectional view of the display/illumination fixture 13 attached to the corner of the building 14, viewed from above. The structure of the display/illumination fixture 13 is the same as that described in FIGS. 1 to 5 above, and the same members are given the same reference numerals. Thereby, the corners of the building 14, which can be called dead spaces, can be effectively utilized.

[Effects of the Invention] As described above, the display/lighting device of the present invention can not only display information, etc., but also be used as road lighting (street light) at night and as a sign for preventing danger. It is also possible to install it on utility poles or the corners of buildings.
