Description

Lighting device for vehicle roof glass {LIGHTING DEVICE FOR ROOF GLASS OF VEHICLE} The present invention relates to a lighting device for a vehicle's roof glass, and more specifically, to a lighting device that directs output light onto the vehicle's roof glass through a transparent reflector integrally coupled to a light-emitting diode. Vehicles were traditionally regarded merely as a means of transportation, and because the number of manufacturers was limited, the aesthetic appeal of the interior was not a major consideration. However, recently, vehicles are being viewed not only as a means of transport but also as a way to express the user's status and individuality. With the increase in manufacturers creating a competitive market, there is growing interest in the aesthetic appeal of vehicle interiors. Mood lighting devices are installed in various locations both inside and outside the vehicle, such as the ceiling, door panels, dashboard, and footwells. These devices are designed to enhance the driver's senses and improve the atmosphere inside the vehicle while driving or stopped. Among them, the mood lamp of the loop glass irradiates light from the side of the glass processed with a fine ceramic pattern, and the irradiated light is incident on the glass and reflected by the ceramic pattern to form a lighting pattern. However, conventional roof glass mood lamps had a problem in that noise or sounds were generated due to vehicle vibration in relation to the roof glass or other components of the vehicle. Conventional technology refers to technical information that the inventor possessed for the derivation of the present invention or acquired during the process of deriving the present invention, and it cannot necessarily be considered publicly known technology disclosed to the general public prior to the filing of the present invention. FIG. 1 is a downward perspective view of a lighting device for a roof glass of a vehicle according to an embodiment of the present invention. FIG. 2 is an enlarged view in direction A of FIG. 1 of a lighting device with the first glass removed according to an embodiment of the present invention. FIG. 3 is a schematic cross-sectional view of a lighting device for a roof glass of a vehicle according to an embodiment of the present invention. FIG. 4 is a light pattern formed on a loop glass according to an embodiment of the present invention. FIG. 5 is a diagram showing the state in which a lighting device for the roof glass of a vehicle is installed according to an embodiment of the present invention. In the present invention, the attached drawings may be illustrated with exaggerated expressions to distinguish it from the prior art, ensure clarity, and facilitate the understanding of the technology. Furthermore, the terms described below are defined considering their functions in the present invention; since these terms may vary depending on the intentions or conventions of the user or operator, their definitions should be based on the technical content throughout this specification. Meanwhile, the embodiments are merely exemplary details of the components presented in the claims of the present invention and do not limit the scope of the rights of the present invention; the scope of rights should be interpreted based on the technical concept throughout the specification of the present invention. Throughout the specification, when a configuration is described as "including" a configuration, this means that, unless specifically stated otherwise, it does not exclude other configurations but may include additional configurations. Furthermore, when it is said that one configuration is "connected," "connected," or "combined" with another configuration, this means that it is not only "directly connected," "directly connected," or "directly combined," but also that there may be cases where it is "connected with another configuration interposed," "connected with another configuration interposed," or "combined with another configuration interposed." On the other hand, when it is said that one configuration is "directly connected," "directly connected," or "directly combined" with another configuration, it should be understood that there is no other configuration in between. In addition, when directional terms such as "front," "back," "up," "down," "left," "right," "first end," "other end," and "both ends" are used, they are used exemplarily in relation to the orientation of the disclosed drawings and should not be interpreted restrictively, and when terms such as "first" and "second" are used, they are terms used to distinguish each configuration and should not be interpreted restrictively.
