본 고안은 LED 표시 장치의 전원공급 장치에 관한 것으로서, 특히 대형 LED 표시 장치에 LED밝기가 균일하게 점등되게 각 블록기판마다 일정한 전원을 공급할 수 있도록 한 대형 LED 표시 장치의 전원 분산 장치에 관한 것이다.The present invention relates to a power supply device for an LED display device, and more particularly, to a power distribution device for a large LED display device capable of supplying a constant power to each block substrate so that the LED brightness is uniformly lit on the large LED display device.
LED 표시장치의 대형화 추세에 따라 부하(LED)가 증가하게 되면 각 부하에 안정된 전원을 공급할 수 있는 장치가 필요하게 되며, 특히 대형 LED 표시 장치의 LED가 부착된 블록이 여러개로 연설되어 있어 블록기판이 많을 경우에는 더욱 전원 공급 장치가 절실하며, 만일 각 LED에 일정한 전원에 인가되지 못할 시에는 밝기가 균일하지 못하는 현상이 나타나게 된다.As the LEDs increase in size, as the load (LED) increases, a device capable of supplying stable power to each load is needed. In particular, a block board with a large number of LED-attached blocks on the large LED display is speeched. In many cases, the power supply is urgently needed, and if the LEDs are not applied to a constant power source, the brightness is not uniform.
따라서 각 블록 기판에 안정된 전원을 공급하기 위해서 여러가지 방식이 사용되었으나 그 중에도 제 2 도에서와 같이 전원에 많은 부하를 접속할 경우에는 I=I1+I2+I3+… In가 되어 각 부하의 전류 상태등이 서로 영향을 미치게 되어 안정된 전압 공급이 어려워지게 되며 또한 제 3 도에서는 각 부하에 전원선을 연결하여 동일한 전원이 인가될 수 있고 각 전류 통로가 별도이므로 각 부하간의 상호 영향은 없어지나 LED 표시 장치가 대혈화되면서 전원으로 부터 멀리 위치한 부하의 전압 제어가 힘들며 단일 전원의 과부하로 인한 방열 문제가 제기되고 또 전원선이 길어지면 전자기파 발생이 많아 타부품에 영향을 주며 도선의 길이에 따른 전력 전송 손실로 인한 전압 강하가 일어나는등 많은 문제점이 야기되었던 것이다.Therefore, in order to supply a stable power to each block substrate, but various methods are used during the connection if a heavy load on the power supply, as shown in FIG. 2 is I = I 1 + I 2 + I 3 + ... It becomes I n and the current state of each load affects each other, making it difficult to supply stable voltage. Also, in FIG. The mutual influence between the loads is eliminated, but as the LED display device becomes larger, it is difficult to control the voltage of the load located far from the power source, and the heat radiation problem is caused by the overload of a single power supply. Many problems have occurred such as voltage drop due to power transmission loss along the length of the wire.
그러므로 본 고안은 전술한 바와 같은 문제점을 해결하기 위하여 안출된 것으로 대형 전원을 여러개의 소형전원으로 분산시키고 각 부하 마다 소형전원이 인가되게 하여 종래의 결합을 완전히 해소하고 전원부의 이상발생시 위험을 분산시켜 LED 표시 장치의 신뢰성 향상에 기여하도록 하는데 본 고안의 목적이 있는 것이다.Therefore, the present invention was devised to solve the problems as described above. The large power is distributed to several small power supplies, and the small power is applied to each load, thereby completely eliminating the conventional coupling and distributing the risk when an abnormality of the power supply occurs It is an object of the present invention to contribute to improving the reliability of the LED display device.
이하 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.
제 1 도에서와 같이 제어회로(1)에 의해 동작하는 통상의 대형 LED 표시 장치에 있어서, LED가 연설된 각각의 블록기판(3-3-n)에 소형 전원부 (2-2-n)를 접속하여 블록기판(3-3-n)에 알맞는 전원이 인가되도록 하되, 각 블록기판(3-3-n)간에 전원의 극성을 동일 극성으로 엇갈려 연결하여서 된 것이다.In a typical large-size LED display device operated by the control circuit 1 as shown in FIG. 1, a small power supply unit 2-2-n is provided on each block substrate 3-3-n to which the LED is spoken. The power supply suitable for the block board 3-3-n is applied by being connected, and the polarities of the power supply are alternately connected between the block boards 3-3-n with the same polarity.
상기와 같은 구성으로 이루어진 본 고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention made of the above configuration as follows.
제어회로(1)에서 지시된 내용을 블록기판(3-3-n)에 나열되어 있는 LED의 점등에 의해 표시되는데 이러한 LED의 점등은 각 블록기판(3-3-n)마다 접속되어 있는 전원부(2-2-n)의해 독립적으로 전원이 인가됨으로서 타블록기판(3-3-n)의 각 점등에 따른 전류의 변화에 영향을 받지 않게 되므로 안정된 전류를 공급받아 항시 동일한 밝기로 LED가 점등된다.The contents indicated by the control circuit 1 are indicated by the lighting of the LEDs listed on the block board 3-3-n. The lighting of these LEDs is connected to each block board 3-3-n. As the power is applied independently by (2-2-n), it is not influenced by the change of current according to each lighting of other block board (3-3-n). do.
따라서 각 부하에 인가되는 전압 제어가 필요치 않으며 도선의 길이가 연장됨에 따라 발생되는 전자 기파의 발생을 제거하여 타부품에 영향을 주지 않고, 또한 블록기판(3-3-n)간에 전원부를 동일 극성을 엇갈리게 하여(-++--+…)타블록기판(3-3-n)으로 전원이 흐르지 못하게 하므로서 전압 변동을 극소화하여 전력 손실을 방지할 수 있도록 되어 있다.Therefore, it is not necessary to control the voltage applied to each load, and eliminate the generation of electromagnetic waves generated by the extension of the conductor length so as not to affect other parts, and also have the same polarity of power supply between the block boards (3-3-n). It is possible to prevent power loss by minimizing voltage fluctuations by staggering (-++-+…) to prevent power from flowing to the other block substrate (3-3-n).
이상에서 상술한 바와 같이 본 고안은 개개의 블록기판(3-3-n)에 소형 전원부(2-2-n)를 각각 접속하여 전원을 분산시킴으로서 각 블록기판(3-3-n)의 전류 상태에 따라 서로 영향을 주는 것을 배제하고 전자 기파발생의 억제로 인해 타부품에 간섭을 주지 않을 뿐만 아니라 각 블록기판(3-3-n)간에 전원을 동일 극성으로 연결됨에 따라 전압 강하를 극소화하여 각 블록기판(3-3-n)의 LED에 안정된 일정한 전원이 인가되어 항시 균일한 밝기로 점등될 수 있어 대형 LED 표시장치의 신뢰성을 높이는데 크게 기여할 수 있는 유용한 고안인 것이다.As described above, the present invention connects the small power supply units 2-2-n to the individual block substrates 3-3-n, respectively, and distributes power to each block substrate 3-3-n. By not affecting each other depending on the state, not only does not interfere with other parts by suppressing electromagnetic wave generation, but also minimizes the voltage drop by connecting the power with the same polarity between each block board (3-3-n). The stable constant power is applied to the LEDs of each of the block boards 3-3-n so that they can be always lit with uniform brightness, which is a useful design that can greatly contribute to increasing the reliability of large LED display devices.
