Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-luminous sign such as a road sign or an aviation guide light using electroluminescence (hereinafter referred to as "EL"), which is particularly visible to a driver of a car at night. It relates to a self-luminous sign that is easy to do.

2. Description of the Related Art Conventionally, as a sign at night, a retroreflective type or a self-luminous type using a fluorescent lamp has been mainly used, but in the former case, it is difficult to see with a headlight. However, in the latter case, there is a problem that the size becomes large and the weight becomes heavy. Therefore, recently, as an alternative to these, a label composed of a luminescent material using EL has come to be seen.

The EL device using this EL is also a self-luminous type, but it can have both a light source and a marker.
Further, since the volume occupied by the light source itself is small, there are advantages that it is possible to reduce the weight and size. As an example of this type of marker, the technique disclosed in Japanese Utility Model Laid-Open No. 63-139699 discloses, as shown in FIG. 5, a light-emitting body using an EL that imitates a letter a or a figure b on a substrate d. Become a sign pattern c
Is attached, and an electric field is applied to the sign pattern c by a circuit from a dry battery via an inverter to cause the sign pattern c to emit light, and the sign pattern c can be visually recognized even in the dark.

[0004]

However, the EL itself,
There is a problem that it is weak against ultraviolet rays, especially sunlight, and is also inferior in water resistance and moisture resistance. The present invention has been made for the purpose of solving the above-mentioned problems of the prior art and providing an EL type self-luminous marker excellent in weather resistance, water resistance, moisture resistance and the like.

In the self-luminous marker having such a structure, the white light emitted from the entire surface of the substrate 13 by energization serves as a backlight.
Since the sign pattern 9'is illuminated, the sign pattern 9'is raised in the part where the light beam is blocked and the part where the light beam passes.

[0024]

The self-luminous marker according to the invention of claim 1
Since the surface plate made of a transparent material is arranged in front of the substrate formed of the EL light-emitting body or the marking pattern formed of the EL light-emitting body, the ultraviolet rays of sunlight are transparent to the transparent surface. It is absorbed or blocked by the face plate. Therefore, the weather resistance of the luminescent material composed of EL, and by extension, the sign is improved.

Further, since the substrate and the marking pattern formed of the EL luminous body are housed in the box portion, they are protected from rainwater, dust and the like, and air circulation holes are formed at the bottom of the peripheral wall. Therefore, the temperature and humidity inside the box will not rise abnormally. Therefore, a luminous body made of EL of a substrate or a marking pattern, or a marker itself having improved water resistance, dust resistance, heat resistance, and moisture resistance is obtained, and the marker generally lasts a long time.

The self-luminous sign according to the second aspect of the present invention has substantially the same structure as the self-luminous sign according to the first aspect of the present invention, except that the sign pattern is provided on the back side of the surface plate. As a result, the same or more effect as the above effect of the invention of claim 1 is exhibited.
