Description

Door trim face panel lighting device The present invention relates to a surface panel lighting device for a door trim, and more specifically, to a surface panel lighting device for a door trim that can be used by a vehicle occupant as a mood light or as a liquid crystal screen to receive visual information, thereby simultaneously satisfying the interior aspect of the vehicle and the functional aspect of providing various information. With the recent gradual increase in vehicle consumption and usage, drivers and passengers are spending more time inside vehicles; consequently, there is a growing trend of increasing importance placed on vehicle interiors and emotional quality. Automotive mood lamps are installed inside vehicles to enhance interior aesthetics or emotional quality as described above; they are used to illuminate the vehicle's interior through various colored lights, thereby enhancing the vehicle's interior design. The aforementioned vehicle mood lamps are installed on door trims or crash pads, and are composed of various colored lights, such as line or curved lights, and are used to create the interior atmosphere of the vehicle. In other words, the marketability of a vehicle is significantly influenced by its design, in addition to its mechanical performance. Recently, the importance of interior design has increased alongside exterior design; accordingly, various elements such as the shape, color, layout, and materials of interior components are varied and combined to express feelings of comfort, sophistication, and luxury. In addition, lighting cannot be overlooked as an element of interior design; typically, LED lighting is installed in areas such as the instrument cluster on the center console or the console between the driver and passenger seats to create a unique interior atmosphere depending on the color of the light. Meanwhile, generally, a car door consists of an outer panel forming the outer surface of the car body, an inner panel hemmed to the outer panel, and a door trim attached to the inner panel. Conventional LED lighting is also applied to door trims; for example, LED lamps are installed on one side of the armrest or on the center trim of the door, and are used as general mood lighting and dynamic lighting. However, conventional LED lighting installed on the door trim was used merely as general mood lighting or dynamic lighting, and since it lacked the function to provide visual information and notifications to passengers through various photos and videos, there was a problem with the functionality and efficiency of the lighting. Figure 1 shows the installation location within the door trim of the surface panel lighting device of the door trim according to the present embodiment. FIG. 2 is a drawing showing the side view of the surface panel lighting device of the door trim according to the present embodiment. FIG. 3 is a drawing showing a plan view of a surface panel lighting device of a door trim according to the present embodiment. 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 shows the installation location within the door trim of the surface panel lighting device (100) of the door trim according to the present embodiment, FIG. 2 is a drawing showing the side view of the surface panel lighting device (100) of the door trim according to the present embodiment, and FIG. 3 is a drawing showing the plan view of the surface panel lighting device (100) of the door trim according to the present embodiment. Referring to FIGS. 1 to 3, the surface panel lighting device (100) of the door trim will be described in detail. A door trim surface panel lighting device (100) installed on a center trim (11) located on a door trim (10) of a vehicle according to an embodiment of the present invention comprises: a display unit (110) for displaying visual information including a photograph or video to a vehicle occupant; a light-emitting module (120) installed on one side of the display unit (110) and electrically connected to the display unit (110) and emitting light into the interior of the vehicle; a housing (130) installed on one side of the center trim (11), having a front open and forming a receiving space inside to accommodate the display unit (110) and the light-emitting module (120); and a lens unit (140) installed on the front of the housing (130) and transmitting or diffusing light generated from the display unit (110) or the light-emitting module
