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.

[0002]

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. 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,
It is weak against sunlight, especially ultraviolet rays, and very thin and
Due to its flexibility, it is not affected by mechanical external force such as vibration.
There was a problem that it was easily broken and easily deformed, and it was also inferior in water resistance and moisture resistance. The present invention is described above to solve the prior art problems, weather resistance, water resistance, excellent and vibration to the moisture resistance
Even if mechanical external force such as acts, it is hard to break and deforms
The present invention has been made for the purpose of providing an EL type self-luminous label in which the above phenomenon is prevented .
