Description

Electronic display board {LED DISPLAY PANEL}

The present invention relates to an electronic display panel which is arranged to allow a plurality of LED panels in which the LEDs are arranged to be spaced apart from each other by a predetermined distance so as to secure a wider advertising area using fewer LEDs, and to easily maintain and repair the LEDs. will be.

Advertisement signage is generally used to advertise a business name or handling product name in a store, etc., and is classified in various ways according to its structure or material, and also classified into a signboard, a wallboard, etc. according to an installation method.

The advertising signboard is installed in a place where people can easily see the advertisement text provided through the panel to realize the advertising effect by allowing people to be visually recognized.

In this case, the panel is usually made of an acrylic resin, etc., the form of ad text on the front panel. Thus, there is a disadvantage in that only one ad text attached to the panel is advertised.

In addition, the panel is configured to emit light by installing a plurality of fluorescent lamps inside the panel to enhance the advertising effect even at night. Therefore, a large amount of power consumption is required to drive a large number of fluorescent lamps. In addition, when a state of a specific fluorescent lamp of the plurality of fluorescent lamps is poor, there is a problem in that the ad text displayed on the outside of the electronic display board is stained.

Therefore, recently, an advertisement signboard using LEDs that can provide various advertisement information by changing has been proposed.

In general, the electronic display board is arranged to provide a number of LEDs on a single panel, by providing the LED control information corresponding to the advertising text in the control device to the LED, to provide a variety of advertising text through each LED drive.

On the other hand, in recent years, chip type LEDs have been developed. That is, as shown in FIG. 1, the phosphor 2 is coupled to the upper side of the surface emitting LED chip 1, and the lower side of the LED chip 1 protrudes through the board 3 so that an external power source is provided. Configured to receive (Vcc). The transparent cover 4 is coupled to the outside of the substrate 3 to surround the LED chip 1 and the phosphor 2.

Here, the LED chip 1 is configured in the form of a rectangular chip, as shown in Figure 2a is to control the light emitting the desired color by emitting the phosphor 2 as the power is applied from the outside, the LED chip (1) Since the chip type LED using a general configuration, its detailed description is omitted.
