Problems solved by technology

[0006] Therefore, vehicle panels are being developed that go beyond the limits of conventional simple linear lighting, but even in vehicle panels that include three-dimensional patterns, visibility is still low or the three-dimensional effect is still poor

Embodiment 1-1-1

[0090] (Three-dimensional pattern part) An opaque carbon dioxide containing 99.994% by weight of polycarbonate and 0.006% by weight of a carbon black-containing pigment was produced by mixing polycarbonate (PC) as a base material and a carbon black-containing pigment using a twin-screw extruder. Esters (gray 100%; SM100). At this time, the three-dimensional pattern part is composed of a plurality of unit parts with a thickness of 3.0 mm, and the shape of the three-dimensional pattern contained in the three-dimensional pattern part has a rhombus bottom surface, and the engraving depth is 0.2 mm to 0.8 mm.

[0091] (Coating part) A coating part is manufactured by mixing a light-transmitting black high-gloss paint as a colorless paint, and carbon black, an azo compound, and a phthalocyanine compound as a pigment, and then the manufactured coating part is exposed to UV light. The photocurable type is coated on the upper surface of the manufactured three-dimensional pattern portion...

Embodiment 1-1-2 and Embodiment 1-1-3

[0096] Compared with Example 1-1-1, a vehicle panel was produced in the same manner as in Example 1-1-1, except that the coating portion was produced with a thickness of 10 μm to 11 μm (50%), thereby producing a coating containing 2.5 % of the pigment coating part (Example 1-1-2), or to produce a coating part with a thickness of 14 μm to 15 μm (70%), thereby producing a coating part containing 3.5% of the pigment (Example 1-1 -3).

Embodiment 1-2-1 to Embodiment 1-2-3

[0098]Compared with Example 1-1-1 to Example 1-1-3, the vehicle panel was manufactured in the same manner as in Example 1-1-1 to Example 1-1-3, except that the 1.5mm A thickness of 3.0mm instead of a thickness of 3.0mm produces a three-dimensional pattern part.

Abstract

The present application relates to a vehicle panel emitting light in a three-dimensional gradient pattern, the vehicle panel comprising: a panel main body comprising a three-dimensional pattern portion and a coating portion, the three-dimensional pattern portion comprising a three-dimensional pattern engraved on a rear surface of the three-dimensional pattern portion, and a coating portion coated on an upper surface of the three-dimensional pattern portion, and an illumination portion provided so that light is emitted from an inner surface of the panel main body, in which the illumination portion includes: a diffusion plate provided to be spaced apart at a position corresponding to the panel main body, and a light source provided to emit light from the inner surface of the panel main body; the light source is located on the inner side of the diffusion plate and arranged to be separated from the diffusion plate.

Description

technical field [0001] The present application relates to vehicle panels that emit light in a three-dimensional gradient pattern. Background technique [0002] The statements in this section merely provide background information related to the present application and may not constitute prior art. [0003] In recent years, interior ambient lighting in vehicles has generally been applied to high-quality products. In general, linear lighting has been widely used around the world, and in order to apply the above-mentioned linear lighting, researches have been done on linear-structured light-emitting objects (such as light guides or light strings). In recent years, the European industry has mass-produced planar lighting decoration components using films, and when mainly producing films for in-mold labeling (IML) or in-mold decoration (IMD) methods, a selective shielding structure is formed, and by changing the film layer The number of printing colors in between to achieve the l...
