Architectural LED landscape rod installed on the exterior of an outdoor building {LED FRAME FOR ARCHITECTURE}

The present invention relates to an LED landscape rod for construction, and more particularly, while the outer housing is directly exposed to the outside, while the diffuser plate is mounted inside the outer housing, light passes through a through hole formed in the outer housing to the outside. By being configured to emit light, the diffusion plate is not directly exposed to direct sunlight or harsh external environment, so that deformation or yellowing does not occur, and furthermore, the exterior of the building can be decorated with various colors of the LED module at night, as well as the outer surface of the outer housing. It is about an architectural LED landscape rod that can create a conceptual building exterior even during the daytime because it can be implemented with paints of various colors instead of white.

In general, in buildings, a number of walls are formed between the ceiling slab and the floor slab to separate rooms and other spaces. installed so that

After the wall of such a building is constructed, the outer wall of the wall is decorated to increase the beauty of the exterior of the building and to protect the wall layer. It is designed to install finishing materials on various types of panels, such as panels, various wooden panels, aluminum panels, ALC, and EPS.

However, such a conventional exterior finishing material installation method has a problem in that it is difficult to provide identification to outsiders as well as a feeling of anti-aesthetic because it has a typical color due to the characteristic of the finishing material.

In order to solve this problem, various attempts have been made to decorate the exterior wall of the building by installing a landscape rod having a built-in LED module along the exterior wall of the building.

As can be seen in FIG. 5 , the conventional tube rod is configured such that a U-shaped PC is fitted to the open side of a U-shaped plastic housing, and the PC itself emits light by an inner LED module.

However, since the conventional landscape rod adopts a structure in which the PC is directly exposed to the outside, the PC is exposed to direct sunlight or a harsh external environment. There was a problem in that the appearance was damaged by staining when irradiated with light.

In addition, in the conventional landscape rod, since the PC itself is generally made of transparent or off-white color, the color of the landscape rod can only be composed of white color. Since only the scenery sticks are visible, it has a limitation in that it is not possible to produce a variety of colors exposed during the day.
