Description

Organic lighting system

The present invention relates to a lighting technology, in particular to an organic lighting system.

In today's society, a vehicle is not just a means of transportation, it is more likely to be another living area besides the office or home. Therefore, many people have bright needs for the space in the car, such as makeup, reading, and even socializing.

However, traditional interior lighting facilities often fail to meet these needs. Sometimes the brightness is not enough, and sometimes it is too dazzling. Therefore, it is necessary to propose a lighting system that can be used in a car, which can protect the eyes and have sufficient brightness.

The present invention provides an organic lighting system for a vehicle. The vehicle includes a vehicle body and a vehicle power supply. The organic light system may include an organic planar light source, which has a light-emitting surface and can emit light in the vehicle. The organic lighting system may further include a lamp body assembly surrounding the organic planar light source, wherein the lamp body assembly is connected to the vehicle body. The organic lighting system may further include a movable cover plate partially covering the organic planar light source and connected to the lamp body assembly.

The above-mentioned lamp body assembly does not require a space to house a plurality of lamp bodies of traditional point-shaped luminous bodies, but only needs to house an organic planar light source. The organic planar light source can have a continuous, soft and uniform light-emitting surface. The light emitted by the organic lighting system of the present invention is soft, not dazzling, and relatively uniform, so the brightness can be brighter than traditional light sources.

The organic lighting system of the present invention may further include a connector, so that the circuit assembly is electrically connected with the vehicle power supply. The organic light system of the present invention can be a makeup mirror light, a reading light, an atmosphere light, or a trunk light.

In this way, with the structure of the above-mentioned embodiment, the lamp body assembly of the organic lighting system does not need space to accommodate a plurality of lamp bodies of traditional point-shaped luminous bodies, but only needs to accommodate one organic planar light source. The organic planar light source can have a continuous, soft and uniform light-emitting surface. In addition, the light emitted by the organic lighting system is soft and not dazzling, and is relatively uniform, so the brightness can be brighter than traditional light sources.
