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 portion to be formed is generally such that a translucent resin material 3 is formed from above and below on the cutout character portion 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 Utility Model Application Publication No. 48-67669 and Utility Model Application No. 58-41641).

Problems to be Solved by the Invention However, since the board 4 of the conventional number plate is molded with a transparent resin material 3 in the shape of letters on both the front and back sides, it is difficult for each character to have the shape of the letters on both the top and bottom. It requires a mold, and depending on the placement of the light source behind it, the brightness of each character may vary.
Furthermore, there is a problem that light entering from the corners of the resin material 3 on the back side is polarized or diffused due to the prism effect, making some parts too bright.

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 fills the cut-out character portion with a translucent resin material. 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 On the back side, a translucent plate part that extends over the entire punched character part is integrally formed with the resin material, and a rib that rises toward the rear is formed on the outer periphery of the translucent plate part, and the rib extends approximately along the inner periphery of the rib. It is characterized by a shaped electroluminescent lighting panel.

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. A rib 12 rising rearward is integrally formed on the outer periphery of the plate-shaped portion 9. 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 having ribs from the back surface with the substrate 7 in between.

A plate-shaped portion 9 on the back side of this license plate body 5
The shape of can be set freely depending on the forming position of the punched characters 8, and in mounting, as shown in FIG. Alternatively, the space surrounded by the ribs 12 is used as a storage room for the lighting panel 10. Then, a back cover 11 is provided to protect the ribs 12 of the plate-shaped portion 9 and the electroluminescent lighting panel 10. Note that the board 7 is provided with a mounting hole 13 for attaching to the vehicle body.

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 cross-sectional view of a license plate according to another embodiment of the present invention, in which 6 is a resin material, 7 is a substrate, 8 is a cutout, 9 is a plate-shaped portion made of a translucent resin, and 10 is an electroluminescent plate. The mold lighting panel, 11 is a back cover, and 12 is a rib, and these structures are almost the same as in the above embodiment, but in this embodiment, a hook-shaped portion 14 is formed at the end of the rib 12.

In the license plate of this embodiment configured as described above, if the electroluminescent lighting panel 10 is formed of a flexible sheet, the electroluminescent lighting panel 10 can be inserted into the hook-shaped portion 14 around the entire circumference of the rib 12. The electroluminescent lighting panel 10 can be fitted and fixed by its elastic repulsive force. In addition, when the electroluminescent lighting panel 10 is sealed with a glass plate or the like, the hook-shaped portions 14 are formed at the ends of the ribs 12 on the three sides of the solid periphery of the plate portion 9, and the electric field is applied from the other side. By sliding and inserting the light-emitting lighting panel 10, it can be fixedly held.

The license plate configured in this way has the 6th
As shown in the figure, the board 7 of the license plate body 5
Insert the bolt 16 into the mounting hole 13 through the washer 15.
A spacer 1 is provided between the substrate 7 and the bumper 18 so that the substrate 7 of the license plate 5 does not press the plate portion 9 and the electroluminescent lighting panel 10.
7 and insert the bolt 16 into the hole 19 of the bumper 18.
Pass it through and secure with a nut. Further, as shown in FIG. 7, the spacer 17 may be extended to form a cover 20 to protect the electroluminescent lighting panel 11.

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 shape 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 forming a rib on the outer periphery of the plate-shaped part and arranging the electroluminescent lighting panel along the inner periphery of the rib, the light emitted from the electroluminescent lighting panel that has passed through the plate-shaped part and the light that has been guided can be There are advantages in that the character portion can be efficiently illuminated, efficient illumination can be obtained, and the ribs can ensure the placement of the illumination panel.
