Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an optical license plate in which characters are formed using a translucent resin material in cut-out characters formed on a substrate.

Conventional technology Conventionally, optical license plates have used lamps, electroluminescent lighting panels, etc. as light sources to illuminate translucent characters cut out on the plate body. The structure of the translucent character part to be formed is generally such that a translucent resin material 3 is molded from above and below on the cutout character part 2 of the plate body 1, as shown in FIGS. 6 and 7. (See Special Publication No. 46-4316).

Further, a light source such as a lamp or an electroluminescent lighting panel is arranged behind the substrate 4 configured in this way,
Each character is transparently illuminated (see U.S. Pat. No. 48-67669 and U.S. Pat. No. 58-41641).

Problems to be Solved by the Invention However, since the board 4 of the conventional license plate has a transparent resin material 3 molded in the shape of letters on both the front and back sides, the individual letters are covered with gold in the form of letters on both the top and bottom. It requires a mold, and depending on the position of the light source behind it, the brightness of each character will vary, and furthermore, due to the prism effect of the light entering from the corners of the resin material 3 on the back side, some parts will become too bright. There are other problems.

Furthermore, electroluminescence type lighting panel lighting is known from Japanese Utility Model Publication No. 37-25741, Japanese Patent Application Laid-Open No. 11526-1982, Japanese Unexamined Utility Model Publication No. 41642-1982, etc., but all of them have the above-mentioned character form. Located behind the resin material,
Alternatively, it is disposed behind the cut-out characters on the license plate body, and from a mounting point of view, it is desirable to have a structure that effectively illuminates the characters with the light from the electroluminescent lighting panel.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention forms predetermined cut-out characters on the non-transparent license plate body, and injects a translucent resin material into the cut-out character portions. In a light-type license plate which is provided with a transparent display using a light source disposed behind the license plate, a character shape is formed using the resin material on the surface side of the cut-out character part of the license plate body, and The invention is characterized in that on the back side, a light-transmitting plate portion that extends over the entire cut-out character portion is integrally formed of the resin material, and further, an electroluminescent lighting panel is arranged facing the light-transmitting plate portion.

Effects According to the present invention, a light-transmitting plate section is provided with resin on the back side of the license plate body, and an electroluminescent lighting panel is placed facing it, so that the light guided inside the plate section can be effectively used to illuminate the characters. To illuminate a part, enable efficient illumination, and ensure the arrangement of a lighting panel.

Embodiment FIG. 1 is a plan view of a license plate according to an embodiment of the present invention, FIG. 2 is a back view of the license plate of FIG. 1, and FIG. 3 is a sectional view of the license plate of FIG. License plate body 5 shown in Figure 1
The surface of the license plate body 5 has a resin material 6 raised up over the cutout letters 8 of the substrate 7, and the back side of the license plate body 5 shown in FIG. do. Note that this configuration can be formed by injecting a resin material into a letter-shaped mold from the front surface of the license plate body 5 and a plate-shaped mold from the back surface with the substrate 7 in between.

As shown in FIG. 4, an electroluminescent lighting panel 10 is mounted on the back side of the license plate body 5,
A back cover 11 is provided to protect the plate portion 9 of the license plate body 5 and the electroluminescent lighting panel 10.

Since this embodiment is configured in this way, the plate-shaped portion 9
The text portion can be efficiently illuminated by the light emitted from the electroluminescent lighting panel 10 and the guided light. Note that if the back surface of the plate-like portion 9 is made finely uneven, the light emitted from the electroluminescent lighting panel 10 will be diffused, and more uniform illumination can be achieved.

FIG. 5 is a sectional view of a license plate according to another embodiment of the present invention and a rear view of the license plate body, where 5 is the license plate body, 6 is a resin material, and 7 is a back view of the license plate body.
8 is a board, 8 is a cut-out character, 9 is a plate-like part made of a translucent resin, 10 is an electroluminescent lighting panel, and 11 is a back cover, and these structures are almost the same as those of the above embodiment, but this embodiment In the embodiment, ribs 12 are formed by extending the sides of the plate-shaped portion 9, and the electroluminescent lighting panel 10 is sandwiched between the ribs 12. Note that 13 is a mounting hole.

In this embodiment configured in this manner, the same effects as in the above embodiment can be obtained.

Effects of the invention As is clear from the above explanation, the present invention has a resin material raised on the front side in the form of cut-out characters on the board, and a resin material integrally formed on the back side as a plate-like part where all the characters are connected. By arranging the electroluminescent lighting panel facing the plate, the text area can be efficiently illuminated by the light emitted from the electroluminescent lighting panel that passes through the plate and the guided light, reducing waste. It has the advantage of being able to provide illumination.
