Description

  The present invention relates to the illumination of the main tree. More specifically, the present invention is a book that enhances its decoration effect by installing an EL as a light source on the inner side of a decorative plate of a main tree decoration part such as an automobile part and shining the grain. Concerning wood illumination.

  Conventionally, in automobile interiors, there are parts for decoration purposes in addition to functional parts. Some of them are decorated with decorative and decorative parts that represent wooden patterns, and the ones that represent the patterns using real trees are simulated with the grain of wood, film, etc. Is said to be woodgrain. And these parts are used for an instrument panel and a door trim as a center cluster, a handle, or an ornament.

In recent years, many lamps with decorative elements have been incorporated in the company. The foot lighting under the instrument panel and indirect lighting to the center cluster and pillars have the role of creating the mood in addition to the lighting function of illuminating. In addition, lighting is used as illumination, for example, with a variety of colorful colors.
As the degree of importance of decorative parts increases in this way, as shown in Japanese Patent Application Laid-Open No. 2002-205500, a natural grain is lit by an LED to enhance the decorative effect of the handle, and the effect can be achieved even at night or in the absence of external lighting. There is a technique for shining the fabric in a space-saving manner by electroluminescence (hereinafter referred to as LE) as shown in Japanese Patent Publication No. 2003-523891.

  FIG. 4 is a diagram for explaining the technique described in Japanese Patent Laid-Open No. 2002-205500. The light guide 3 is disposed on the back surface of the plate 1 through the phosphor 2, and the light source 5 in which a large number of LEDs 4 are arranged facing the back surface or side surface of the light guide 3 is emitted. It constitutes a decoration device. When the main wooden decoration part of a vehicle is manufactured using such a technique of Japanese Patent Application Laid-Open No. 2002-205500, the LED 4 and the light guide 3 which are light sources are added to the conventional one, so that the part becomes thicker. It is inevitable that it will end up. This has a great influence on the mounting structure of the conventional decorative parts of the main wood, and it is expected that the structure will be forced to change significantly.

In an automobile internal structure, there are many cases where space is limited for mounting, and door trims and head liners that are expected to be equipped with parts by this technology have a narrow space between the vehicle outer plate, and this case is particularly applicable.
In addition, when there are a large number of light sources, unevenness in light emission always occurs. In this technique, this is solved by interposing a phosphor layer, but it is impossible to completely eliminate light emission unevenness. Since the light is emitted from the component side, when the main tree area is large, it becomes difficult for light to reach the center, which is particularly disadvantageous.

A technique for saving space is described in JP 2003-523891 A. As shown in FIG. 5, this comprises a fabric 8 applied to either or both of a substrate 6 and a foam layer 7, and the EL panel 9 comprises the fabric 8 and the substrate 6 and / or the foam layer 7. The fabric 8 can be illuminated by the light emission of the EL panel 9. However, this technique can also save space, but when the EL panel 9 is not lit, the fabric 8 remains as it is, and it is difficult to say that it is excellent in decorative and aesthetics.

An object of the present invention is to solve the problems of the conventional techniques as described above.
The object of the present invention is to install an EL that emits surface light on the inner side of the decorative board of the main wooden decorative part, thereby suppressing a significant increase in thickness from existing products and making the wood grain pattern shine evenly. It is to provide Motoki decoration parts with high decorativeness and aesthetics.
These and other objects of the present invention will be readily understood from the following detailed description.

  The first aspect of the present invention is characterized in that an EL layer 21, an adhesive layer 22, a glue plate layer 23 having a grain pattern, and a clear layer 24 are sequentially laminated on a base material 20. Further, in claim 2, the EL part 25 in which the EL layer 21 is laminated on the base material 27, and the main wood part 26 in which the attaching plate layer 23 and the clear layer 24 are sequentially laminated on the light transmissive base material 27. And the main tree part 26 is assembled on the EL part 25. The third aspect is characterized in that an EL layer 21, an adhesive layer 22, a film layer 29 having a wood grain pattern, and a clear layer 24 are sequentially laminated on a base material 20.

  According to the present invention, as will be understood from the following detailed description, the EL pattern serving as the light source is installed inside the decorative plate of the main wood decoration parts such as automobile parts, so that the wood grain pattern can be illuminated uniformly. It is possible to prevent the effect from changing over the entire area even for a wide light emitting area. Moreover, since the thickness of EL is thin, it is possible to suppress a significant increase in thickness from existing products. This leads to avoiding a significant increase in the space required for mounting the parts on the vehicle, and the design change accompanying the addition of functions can be minimized. As described above, the present invention can also provide merit in both decorativeness and design.

Subsequently, the present invention will be described with reference to examples thereof. Needless to say, the present invention is not limited to these examples.
