2. Description of the Related Art There is a conventional light license plate shown in FIG. In FIG. 7, reference numeral 1 denotes a case formed in the shape of a flat rectangular container. An illumination lamp 2 is arranged and fixed at a predetermined position in the case 1, and a rectangular shape is provided on the upper surface (front side) of the case 1. The mounting frame 3 is mounted so as to be openable and closable, and the license plate 4 for an ordinary vehicle is fixed to the mounting frame 3 with machine screws.

The license plate 4 is formed by forming a rectangular character board 5 covering the upper surface of the case 1 with a metal plate, and locally punching out the inner peripheral portion of the character board 5 to form a character corresponding to a predetermined character. Hole 6 is formed and surface (upper surface) 5a
A white paint is applied to and the meat character 7 formed of a light-transparent plastic material colored in green and having a predetermined thickness is fixed to the character hole 6.

The above-mentioned meat character 7 has a line width W1 of the character main body 7a slightly smaller than the line width W2 of the character hole 6 formed in the character substrate 5, and extends from the base (lower part) to the top (upper part). Is formed in a rectangular cross-section having an equal width, and a wide flange 7b is integrally formed on the base of the character main body 7a. The character main body 7a is fitted into the character hole 6 from the back side of the character substrate 5. The top portion is projected outward from the front surface 5a of the character substrate 5, and the flange 7b is brought into contact with the back surface 5b of the character substrate 5 and fixed by an adhesive material.

[0005]

In the above-mentioned conventional apparatus, when the illuminating lamp 2 is turned on at night or the like, the light beam is emitted from the character hole 6 to the outside through the meat character 7, and the meat character 7 turns green. It can shine and be easily recognized by a third party.
However, the conventional device described above has a drawback that when the illumination lamp 2 is turned off at night or the like, the meat characters 7 are not illuminated and it is difficult for a third person to recognize it. It is an object of the present invention to obtain a novel light-sensing license plate that overcomes the above drawbacks.

[0006]

Means for Solving the Problems The present invention has the following configuration to achieve the above object. That is,
An opaque character substrate is locally punched out to form a character hole corresponding to a predetermined character, and a meat character made of a translucent material having a predetermined thickness is protruded and fixed to the character hole. In the above-mentioned licensed light license plate, a retroreflector is provided at least on the top of the above-mentioned meat characters. In this case, it is preferable to form a concave portion on the back surface of the meat character. Further, it is preferable that the meat character is formed in a trapezoidal cross section in which the line width of the character gradually becomes narrower from the base to the top.
