Description

Interior mood lighting of a vehicle The present invention relates to an interior mood lighting device for a vehicle, and more specifically, to an interior mood lighting device for a vehicle that includes a lens and a parabolic reflective surface to prevent color separation of a multi-color light source and can be installed in a narrow space. Lighting in automobiles includes exterior lighting such as headlights and interior lighting such as roof lamps. In recent automobiles, subtle mood lighting, known as ambient lighting, is installed on the instrument panel, various gauges and devices on the console, and cup holders to pursue a more sophisticated and luxurious interior design. Such mood lighting is widely applied to door trims, dashboards, glove boxes, armrests, etc., and the range and scope of its application are gradually diversifying. At this time, a method is used to refract light with directional properties through optical devices such as lenses so that mood lighting can be directed toward a suitable target surface inside the vehicle. However, in the case of lenses, color separation occurs in lighting using multi-color light sources due to differences in refractive index depending on the wavelength of light. Additionally, since lenses have limitations in refraction, a large space is required to project mood lighting onto a target surface; however, lighting design is restricted due to the spatial constraints of the interior trim where the mood lighting is installed.

FIG. 2 is a cross-sectional view schematically showing the coupling relationship between the light-emitting part and the base of an indoor mood lighting device according to one embodiment of the present invention. FIG. 3 is a cross-sectional view schematically showing the connection relationship between the base and the cover of an indoor mood lighting device according to one embodiment of the present invention. FIG. 4 is a cross-sectional view showing the installation of an indoor mood lighting device according to one embodiment of the present invention. FIG. 5 is a diagram showing the characteristics of a parabolic reflective surface according to one embodiment of the present invention. The following describes the embodiments of the present invention in detail with reference to the accompanying drawings. The following embodiments are presented to sufficiently convey the concept of the present invention to those skilled in the art to which the present invention pertains. The present invention is not limited to the embodiments presented herein and may be embodied in other forms. In order to clarify the present invention, the drawings may omit the illustration of parts unrelated to the description and may slightly exaggerate the size of components to aid understanding. FIG. 1 is a cross-sectional view schematically showing the installation of an indoor mood lighting device according to one embodiment of the present invention. Referring to FIG. 1, an indoor mood lighting device (10) according to one embodiment of the present invention is mounted on the interior trim (20) of a vehicle and can irradiate light onto the target surface (25) of the interior trim (20) of the vehicle. The interior trim (20) is an interior component placed in the interior space of the vehicle and is provided for the purpose of enhancing the decorative effect of the interior by covering the inner surface of the metal panel on the interior side of the panel provided to form the exterior of the vehicle, while also protecting passengers and luggage from external impacts applied to the vehicle. The interior mood lighting device (10) provides lighting and aesthetic functions for the interior of a vehicle. The interior mood lighting device (10) according to one embodiment of the present invention provides a sophisticated and luxurious interior design by irradiating light onto the target surface (25) of the interior trim (20) of the vehicle. The target surface (25) is the interior-facing (A) surface of the interior trim (20), and receives light irradiated from the interior mood lighting device (10), reflects it back, or shines softly, thereby providing an interior design. The interior mood lighting device (10) is mounted on the interior trim (20) and irradiates light onto the target surface (25). To this end, a protrusion (12), which is at least part of the interior mood lighting device (10), protrudes from the interior trim (20) of the vehicle in the interior direction (A).
