Description

Wireless control type media facade < RTI ID = 0.0 >

[0001] The present invention relates to a media facade, and more particularly, it relates to a media facade which stores a designated pattern to be produced in each smart LED module constituting an LED display that directs a building outside in a desired pattern, To a radio controlled type media facade in which a corresponding pattern is stored by a synchronization frame signal for giving a corresponding control pattern.

Recently, media façade is attracting attention as the interest in urban design is increasing.

Here, the media facade is a compound word of 'Facade' which refers to the center of the exterior of the building and 'Media' which is media art which means media art. It is a combination of LED (Light Emitting Diode) It is a form of digital signage because it uses not only the visual beauty but also the information as a medium to convey information. It is a new type of 21st century architecture combining lighting, image and information technology. It is becoming a trend.

These media facades are characterized by the independence of the envelope from the architectural structure.

The skin of the building is the same as a person 's costume, but it can not easily be taken off or worn once it is worn. As the architectural technology develops, the appearance of the building becomes independent from the structure and the media facade plays a role of catalyst. Due to the expression of digital media, the building envelope can be an independent skin, not a simple building, so the flexibility and autonomy of the building envelope can be amplified and freely designed and expressed, making it an important element to convey the message of the building. have.

And the media facade is characterized by giving emotion to the building.

As the atmosphere changes according to the lighting even in the same space, for example, when the internet and sensors are used, it becomes possible to express mutual connection with human emotions, and thus the building with such sensitivity develops into an organism which communicates with human.

The media facade also has the characteristic of giving stories to buildings.

Media art gives changeable and sustainable stories to architecture. If previous architecture can not communicate directly with human beings, it can be said that messages are implemented with colors, deformed forms, and characters with the help of media art.

As shown in FIG. 1, the media facade has LEDs that replace conventional lighting and display devices in various forms, which are generally longer in life, less power consumption, and easier to control than other lighting means, And an LED display (22) for arranging a plurality of LED lighting devices provided in a bar shape in a large number on a substrate, and controlling the R, G, B values in each LED module (10) However, since it is installed in the form of a large display outside the building, it is necessary to comprehensively consider ease of installation and ease of maintenance after installation.

2A, on the LED module 10 constituting the LED display 22, LEDs 12, which embody R, G and B colors, are provided and connected by a connection wiring 14. The connection wiring 14 includes a power supply line for driving the LED and a signal line for controlling the LED driving.

That is, as shown in FIG. 2B, the conventional method of configuring an LED module requires five wires in order to drive one LED module. In order to supply the VCC power, The DC power supply unit must be supplied with the AC power supply line, so that the number of the connection wiring, the construction installation, and the safety of the AC and DC power supply may be mixed.

Therefore, in the wiring structure of the conventional LED module as described above, it takes a lot of time and cost to install the LED module, and in addition, it is difficult to maintain and manage the LED module unless it is an expert in the aftermath.

In particular, it is necessary to reset the ID or code for the entire LED module in connection with the installation or control of the connection wiring, and moreover, at least several thousands of LED modules are installed outside one building. There is no other choice.

In addition, the LED display configured by arranging the conventional bar-shaped LED modules is disadvantageous in terms of price because all the LED cells are required even when only the characteristic shape is formed as a rectangular structure, and a separate communication channel is connected. There is.

In general, since the multiplexer is used, when the LED cell defect occurs, the cell unit replacement is performed and the A / S cost becomes excessive.

In order to drive the LED module, it is necessary to drive the LED in a state in which the SMPS is built in the module in order to drive one LED module and to control the LED drive wirelessly so that only the AC power line is used as the connection wiring , Construction and installation period was short, post management was easy, and safety problem was solved.
