Description

Vehicle lighting fixtures and vehicles including the same {Vehicle lighting fixtures and vehicle include the same}

The present invention relates to a vehicle lighting device and a vehicle including the same, and more particularly, to a vehicle lighting device provided in a vehicle and capable of generating various types of images by irradiating light into the vehicle interior, and to a vehicle including the same. will be.

In recent years, as the standard of living has improved and the importance of leisure activities has increased, cases of traveling away from the main living space are increasing. For a more convenient and enjoyable trip, it is common to use private vehicles rather than public transportation.

In addition, as is well known through the mass media, so-called "chabak", which is accommodation in a vehicle rather than a traditional type of accommodation, is gaining sensational popularity. That is, the time spent in the interior space of the vehicle is increasing compared to the past, and the demand for the environment of the interior space of the vehicle, that is, the interior, is also increasing.

Accordingly, vehicle manufacturers are developing various attempts to change the interior space of a vehicle into a space where you can feel comfort and pleasure, rather than a space where you simply stay while moving.

Among these various attempts, improvements to indoor lighting referred to as mood lamps can be cited. In the past, it was common to perform only simple tasks or identification of an object by irradiating light into an indoor space using a room lamp or the like. Recently, however, as the time spent in the interior space of a vehicle increases as described above, the demand for lighting is also diversified.

However, it is not easy to provide various types of lighting inside the vehicle. Vehicles are subject to many restrictions on their physical or electrical structures due to safety issues. For example, the interior space of a vehicle must be surrounded by a soft protective function material to prevent injuries to occupants even if they collide.

Furthermore, various devices such as a large number of lamps, a wiring structure for supplying power to the lamps, and a power source are required to form various types of lighting in the interior space of a vehicle. Due to these limitations, it is difficult to secure a variety of interior lighting provided in a vehicle.

Accordingly, techniques for solving the above problems have been introduced.

Korean Patent Registration No. 10-1684122 discloses a headlining hidden lighting device. Specifically, a lighting device installed in a headlining inside a vehicle and realizing lighting that is not exposed to the outside by inserting a lighting source between a headlining fabric and a substrate is disclosed.

However, the headlining hidden lighting device disclosed in the prior art document has a limitation in occupying excessive space. That is, the headlining hidden lighting device disclosed in the prior art document has a structure in which a PCB for controlling the headlining is also mounted on the headlining, and there is a possibility of increasing the thickness of the headlining. Accordingly, when the occupant is tall, the head of the occupant may come into contact with the headlining to cause discomfort.

Even if the PCB is accommodated while maintaining the height of the headlining, it is also difficult to rule out the concern of excessively occupying the space between the upper side of the headlining and the outer frame.

In addition, since the conventional polyimide film material for FPCB having flexibility disclosed in the prior literature contains a conductive thin film, the manufacturing process for configuring the circuit pattern is difficult and complicated, and heat forming is difficult, resulting in various designs and curvatures. It is difficult to maintain and implement this small corner shape.

Korean Patent Registration No. 10-1519757 discloses a vehicle mood light and a lighting method using the same. Specifically, a vehicle mood lamp for realizing mood lighting in the interior of a vehicle by inserting an electroluminescent sheet inside the skin of a headlining surrounding an interior space and a lighting method using the same are disclosed.

However, it is difficult to implement various types of design shapes in the vehicle mood lamp and the lighting method using the vehicle mood lamp disclosed in the prior literature. That is, the vehicle mood lamp disclosed in the prior literature can change its color, but cannot suggest a method for changing the image formed by light without changing the shape of the polyurethane foam supporting the light source.
