Description

[Detailed description of the invention] The present invention relates to an automotive lamp equipped with a new display plate, and is intended to provide an automotive lamp that has particularly good visibility and a luxurious appearance. It is.

Conventional automotive lamps have the manufacturer's trademark etc. stamped directly on the lens surface.

In other words, the letters or symbols of the trademark were formed integrally in the center of the lens in a concave and convex shape during the process of forming the lens.

However, in the case of automobile lamps formed in this way, the trademark is made visible by the difference in the refraction of the light that passes through the part where the letters or symbols are displayed, so it is difficult to see the trademark from a slightly distant position. It was difficult to see and could only be confirmed by looking closely.

Furthermore, since the lens is made of a transparent material made of the same material as the lens, visibility is very poor not only at night but also in dimly lit places.

Therefore, some automobile lamps, such as fog lamps, which also have some decorative meaning, are made by printing trademark letters or symbols on metal tape or the like and adhering them to the lens.

However, these lamps do not have a good appearance, and after many years of use, dust and dirt accumulates on them, and some of them peel off while being washed off. Or it's missing! It had a lot of mold and was not durable.

Therefore, the present invention aims to provide an automobile lamp equipped with a new display plate, particularly an automobile lamp that has good visibility, has a three-dimensional appearance on the display plate, and has a luxurious appearance. A display plate is obtained by adding a display body such as a character or a symbol by printing or the like to the surface of an opaque substrate, covering the display body with a transparent layer, and fixing the display plate to the approximate center of the lens surface. It is characterized by becoming.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the embodiments will be described below with reference to the accompanying drawings showing examples.

FIGS. 1 and 2 show a display plate 1 used in the automotive lamp of the present invention. The display plate is a substrate made of an appropriate material such as an aluminum plate or an opaque synthetic resin plate and having a substantially oblong rectangular shape from the front. A display body 3 of letters or symbols, such as a manufacturer's trademark, is formed on the surface of the display panel 2 by printing or the like, an adhesive layer 4 is provided on the back surface, and the display body 3 is further covered with a transparent layer 5 made of transparent synthetic resin or the like. formed by

Here, the transparent layer 5 covering the display body 3 may be colorless and transparent, or may be colored to the extent that the visibility of characters, symbols, etc. on the display body 3 is not impaired, if necessary.

FIG. 3 shows an example of the implementation of the automotive lamp of the present invention, which is applied to a fog lamp mounted on the front bumper of an automobile.

In the figure, reference numeral 6 denotes a pale yellow letter lens attached to the front surface of the fog lamp 7. The display plate 1 described above is adhered to the lens 6 approximately in the center of its surface by an adhesive layer 4.

However, if you press the button on the invented car lamp as shown above,
Since the characters, symbols, etc. are displayed on the display plate rather than integrated with the lens, the display plate can give a three-dimensional effect and the overall appearance of the lamp can be made luxurious.

Further, since characters, symbols, etc. are provided on the substrate of the display plate by printing or the like, the degree of freedom in design increases.

In other words, when forming a display body by directly forming irregularities on a lens as in the past, it is extremely difficult to express particularly fine details such as complex characters and symbols, and it is time-consuming and costly. However, according to the present invention, even complex designs can be easily expressed, and the color scheme can also be freely expressed.

Furthermore, since the display is covered with a transparent layer, even if the display is peeled off, chipped, or discolored, and even if there is dust or dirt on the surface, it can be easily washed off with water. , helps improve durability.

Furthermore, since the substrate of the display plate is made of an opaque material, it is possible to block the emission of projected light when the lamp is turned on and the emission of natural light reflected by the reflector when the lamp is turned off. This also has the effect of making it easier to visually recognize displayed characters, symbols, etc.

Incidentally, when the display plate is bonded to the substantially central portion of the surface of the lens 7, the following method may be used.

That is, as shown in FIG. 4A, a trapezoidal convex portion 8 having a surface matching the bottom shape of the display plate 1 is integrally provided on the surface of the lens 6, and the display plate is bonded to the surface of the convex portion 8. This has the advantage that the location where the display plate is to be installed becomes clearer.

Further, as shown in FIG. 4B, a recess 9 having a size in which the display plate 1 fits is formed on the surface of the lens 60, and a protruding wall 10 is formed to surround the recess 9. When the projecting wall 10 is glued in the recess 9, if the tip of the projecting wall 10 is at least in front of the substrate 2, the position to attach the display plate will become clearer, and at the same time, the projecting wall 1
A part of the light from the lamp that is incident on the surface 11 of 0 at an incident angle equal to or greater than the critical angle is reflected in the direction of the arrow in the figure and illuminates the display, which has the effect of improving the visibility of the display. .

In the above embodiments of the present invention, the case where the display plate has a horizontally elongated rectangular shape from the front is explained, but if necessary, other shapes such as circular, elliptical, hexagonal, etc. may be used. Although the present invention has been described in the embodiments as applied to fog lamps, it is also possible to apply it to other automotive lighting equipment such as head lamps, rear combination lamps, front turn signal lamps, etc.
