Referring to FIG. 2, the LED lighting apparatus according to the present invention supplies power to the LED assembly 100, the LED board 300 to which the LED assembly 100 is inserted and electrically connected, and the LED board 300. It includes a power supply unit 400.

LED assembly 100 is formed in a specific letter shape, for example 'L' serves to generate light. To this end, the printed circuit board 140 of the LED assembly 100 may be formed in a specific shape desired by the user, and a plurality of LEDs 120 may be mounted on the PCB 140. By doing so, the LED assembly 100 can be configured. Thus, the LED assembly 100 may generate light in a particular shape, for example, the shape of "L", which may imprint the letter 'L'.

Of course, the LED assembly 100 may be formed of letters or numbers, such as 'L', '1', as well as the 'L' shape, to form a specific word 'kim', 'yi', 'bak' as one. It may be. In addition, combining multiple LED assemblies 100 can produce longer words or sentences.

As shown in FIG. 3, as the LED 120, an LED 120 capable of implementing colors of R 122, G 124, and B 126 may be used, and the LED 120 may include a plurality of LEDs 120. Lines For example, four lines 128 may be connected. In the above, although LEDs that can implement R, G, and B are used, LEDs having a single color or two colors may be used.

A connection terminal 200 is formed at one side of the LED assembly 100, and the connection terminal 200 may be formed of a conductor to allow electricity to flow. More specifically, as shown in Figure 4, the connection terminal 200 may be composed of three terminals (R, G, B) to drive the LED consisting of R, G, B, for this purpose The conductive layer 220 and the insulating layer 240 may be sequentially formed to have three conductive layers. Of course, if the LED is composed of any one of R, G, B may be formed of one conductive layer.

The LED board 300 is provided under the LED assembly 100 so that the LED assembly 100 is fitted and electrically connected thereto. The LED board 300 is formed in a plate shape having a plurality of connection portions 320 formed thereon, and the frame 340 made of a plastic or wooden material is coupled to prevent electricity from flowing around the LED board 300.

The connection part 320 may be formed in a circular hole shape to allow the LED assembly 310 to be fitted. When the connection terminal 200 of the LED assembly 100 is fitted to the connection part 320, the connection part 320 may be connected to the LED assembly 100. The LED board 300 is electrically connected. Of course, the shape of the connection unit 320 is not limited thereto, and may be formed in a polygonal shape such as a triangle or a square.

As shown in FIG. 4, the connection part 320 may be formed to have three conductive layers 324 such that three terminals are formed, and an insulating layer 326 is formed between each conductive layer 324. Can be. Here, the conductive layer 324 and the insulating layer 326 of the connecting portion 320 is preferably formed at a position corresponding to the connecting terminal 200 of the LED assembly 100 fitted to the connecting portion 320.

Therefore, as shown in FIG. 5, when the connection terminal 200 of the LED assembly 100 is fitted and coupled to the LED board 300, each terminal of the connection terminal 200 of the LED assembly 100 is connected to the LED board ( It is positioned to correspond to the terminal of the connection part 320 of the 300, and thus the LED assembly 100 and the LED board 300 is electrically connected.

Here, the connection terminal 200 and the connection portion 320 may be formed in a variety of shapes to facilitate the attachment and detachment of each other. In addition, the connection part 320 may be formed by forming a conductive layer only in a part of the region in which the hole is formed, and the connection part 320 may be formed by forming the hole as a whole and forming the hole. .

On the other hand, the LED board 300 is connected to the power supply unit 400 for applying power to the LED board 300. As the power supply unit 400, it is preferable that a small and high-efficiency SMPS is used. Power is applied to the LED board 300 by one SMPS 400, and light is generated in the LED assembly 100 coupled to the LED board 300 to produce a specific word or sentence.

Here, the SMPS 400 is a circuit for switching the electronic devices to each other to make DC to AC, convert it to a desired voltage, and then rectify again to form DC. Such SMPS prevents heat generation and improves power supply. Play a role in achieving this.

In addition, a controller 500 may be further connected between the LED board 300 and the SMPS 400. When power is applied from the SMPS 400, the controller 500 may control the lighting time intervals and R, G, and B of the LED assembly 100 connected to the LED board 300 to be sequentially turned on. The assembly 100 may produce the effect of flickering to make the general public feel aesthetics.

In addition, the controller 500 may be further connected to the sensor unit 600 for detecting sound. The sensor unit 600 may detect a sound by an external sound or a clapping sound, and control the lighting of the SMPS 400 based on the detected sensor information. As a result, the LED assembly 100 may be directed to be turned on by sound, thereby maximizing convenience and beauty. Here, of course, the sensor unit 600 may be installed inside the controller 500 or separately from the controller 500.

As described above, the LED lighting device according to the present invention does not directly connect the SMPS 400 to the LED assembly 100, the LED assembly by connecting the SMPS 400 to a separate plate-shaped LED board 300 By applying power to the 100, it is easy to replace the LED assembly 100 having a specific shape, there is an effect that can easily produce words and sentences of various shapes.

In the above, the LED board of the LED lighting apparatus is formed as one, but may be configured as shown in FIGS. 6 and 7.

As shown in FIG. 6, the LED board 300 is divided into a plurality of left and right spaced apart from each other, and the divided LED boards 300a, 300b, 300c, and 300d are fixed by the outer frame 340. One controller 500 is connected to the divided LED boards 300a, 300b, 300c, and 300d, and the controller 500 is an LED board 300a, 300b, 300c, and 300d in which a plurality of channels 360 are divided. Is connected to each. Here, the number of channels 360 is not limited and may be changed according to the number of divided LED boards 300.

In addition, the controller 500 may be connected to the SMPS 400 for applying power to the divided LED boards 300a, 300b, 300c, and 300d, and the sensor unit 600 may be further connected to the controller 500.

Such a configuration has an effect of simultaneously controlling the divided LED boards 300a, 300b, 300c, and 300d by providing a plurality of channels in one controller 500. Of course, if the channels of the controller 500 are respectively controlled, each of the LED boards 300a, 300b, 300c, and 300d may be individually controlled.

In addition, as illustrated in FIG. 7, the LED board 300 of the LED lighting apparatus is divided into a plurality of parts and fixed to an outer frame, and a plurality of controllers 500 are connected to the divided LED boards 300, respectively. . In addition, a sensor unit is connected to each controller 500, and one SMPS 400 is connected to apply power to the plurality of controllers 500.

In the above, one SMPS 400 is connected to the plurality of controllers 500, but the present invention is not limited thereto, and a plurality of SMPSs 400 may be provided and connected to each controller 500.

In the above configuration, since the controllers 500 are provided on the divided LED boards 300, the direction of the LED boards 300 may be individually controlled. For example, the first LED assembly 100 is configured to be red, the second LED assembly 100 is green, the third LED assembly 100 is blue, and the fourth LED assembly 100 is red and blue at the same time. The lighting time of the LED assembly 100 can be configured differently, such a directing effect has an effect that can increase the aesthetics for the general public.

The invention as described above, with the advantage that can be produced in a variety of ways, even if one of the plurality of controllers fail, the remaining LED board is normally operated can be eliminated that the LED lighting device is not turned on or visually uncomfortable as a whole.
