JP 2009-101840 A

  By the way, in the case of the technique described in Patent Document 1, it is said that the design pattern appearing on the trim surface can be changed by switching on / off the illumination unit. However, with this technique, the pattern of the skin material appears on the trim surface, and there is almost no sense of depth.

  An object of the present invention is to provide an interior part capable of making a design with a sense of depth appear on a design panel with a simple configuration.

The interior component for achieving the above object includes a dark design panel having translucency, a display unit arranged on the back surface side of the design panel and displaying a pattern on the surface facing the back surface, and the design panel And a lamp unit that is disposed between the display unit and emits light toward the display unit, and the pattern is formed of a color paint that reflects light emitted from the lamp unit. The lamp unit is capable of changing the color of light emitted toward the display unit, and the display unit displays a plurality of patterns respectively formed by paints of different colors, Each of the paints reflects light of a corresponding color among the light emitted from the lamp unit, and the lamp units are arranged to face each other and can emit a different color of light. Point light source and the pair of points The light guide disposed between the light sources and the light emission form of each of the point light sources are changed to change the portion of the light guide where light of one color is emitted and the light of the other color. And a control unit that changes a ratio of the light emitted from the portion of the pair of point light sources, and the control unit increases the amount of light emitted from one of the pair of point light sources and By reducing the light emission amount, the display unit increases the proportion of the pattern formed by the paint that reflects the color of the light emitted from one of the point light sources, and the light emitted from the other of the point light sources. The proportion of the pattern formed by the paint that reflects the color of is reduced.

  According to this configuration, the light emitted from the lamp unit is reflected by the pattern portion of the display unit and enters the back surface of the design panel. And when this light permeate | transmits a design panel, the shining pattern with a feeling of depth will appear in the design surface of a design panel. Therefore, a pattern with a sense of depth can be displayed on the design panel with a simple configuration.

  In addition, since the design panel has translucency but is dark, when the light is not emitted from the lamp unit, the presence of the lamp unit and the display unit arranged on the back side of the design panel is difficult to see. . Therefore, it can suppress that the designability of interior parts is impaired.

  When, for example, red light is emitted from the lamp unit, the red light is reflected from a plurality of patterns of the display unit, for example, a portion of a pattern formed in magenta if it is a CMYK paint. And when this red reflected light permeate | transmits a design panel, the pattern which shines in red will appear in a design panel.

  On the other hand, when, for example, blue light is emitted from the lamp unit, the blue light is reflected at a portion of a pattern formed of, for example, cyan among the plurality of patterns of the display unit. And when this blue reflected light permeate | transmits a design panel, the pattern which shines in blue will appear in a design panel.

  Thus, according to the said structure, the pattern and color which permeate | transmit and transmit a design panel are changed by changing the color of the light radiate | emitted from a lamp part. Therefore, the shining pattern and color can be changed with a simple configuration.

  By changing the light emission mode (color, light amount) from each of the point light sources, the ratio of the portion where one light is emitted and the portion where the other color light is emitted in the light guide is changed. By doing so, the pattern and color appearing on the design panel change. Therefore, with a simple configuration, the pattern appearing on the design panel can be moved and its color can be changed, and a visual effect can be effectively performed.

In this case , it is preferable that the background area of the pattern has a black color.
According to this configuration, since the background area of the pattern has a black color, light from the lamp part is absorbed in the background area, and the boundary between the pattern and the background becomes clear. For this reason, it is visually recognized as the pattern appearing on the design panel is floating. Therefore, visual presentation can be performed more effectively.

Further, it is preferable that the display unit is a color printed sheet.
According to this configuration, the display unit can be easily mass-produced by the printing machine.
Moreover, the structure that the said design panel is curving so that it may protrude toward the design surface side is preferable.

  According to this configuration, since the distance between the pattern of the display unit and the design panel changes according to the angle at which the design panel is visually recognized, the shining pattern appears to be deformed. Therefore, it is possible to further emphasize the sense of depth of the shining pattern.
