Description

Lamp apparatus for vehicle The present invention relates to a vehicle lighting device, and more specifically, to a vehicle lighting device capable of implementing a lighting pattern that emits light while varying three-dimensionally. Recently, lighting devices have been evolving from point, line, and plane forms into three-dimensional lighting. For example, research and development is underway on three-dimensional lighting, such as fluorescent lamps that are coiled and twisted in three dimensions or 3D lighting in which multiple LED light sources are arranged in a three-dimensional structure, following point light source incandescent lamps, line light source fluorescent lamps, and plane light source LED flat lighting. 3D stereoscopic lighting typically refers to arranging multiple light sources in a three-dimensional structure and illuminating the arranged light sources in various forms. Such 3D stereoscopic lighting is applied to building exteriors and vehicle lighting devices. A vehicle 3D lighting device applied to some high-end car models is configured to provide 3D lighting by arranging multiple LED light sources in a 3D structure, such as a stepped structure installed along the curved surface of the vehicle, and reflecting light through a mirror formed on the inner surface of the 3D structure. However, conventional stereoscopic lighting devices for vehicles have the disadvantage of increasing costs because they require the use of a large number of LED light sources to cover a wide light-emitting area of the stereoscopic lighting device with LED light sources that have a narrow beam angle to meet the illuminance required for the vehicle. In addition, conventional vehicle 3D lighting devices install 3D lighting based on 3D structures, so in order to create natural 3D lighting, complex structures and control processes are required, such as densely arranging multiple LED lights between 3D structures or gradually controlling the brightness of multiple LED lights to be brighter or darker, and this environment has the disadvantage of ultimately causing increased costs.
