In addition, a separate bracket (not shown) is detachably assembled at the rear of the cover body 21, and is fixedly installed on an outer wall or handrail through such a bracket.

In addition, a sealing member is installed between the first flange 11A of the housing body 11 and the flange 21A of the housing cover 20, and the airtightness of the internal accommodation space of the housing body 11 through this sealing member is Make sure it is secured.

The LED matrix board 30 is installed in the front receiving space among both receiving spaces divided through the partition plate 12 and outputs a graphic such as a character or figure input to the light-transmitting cover 40 to be described later.

This LED matrix board 30 is a board having a predetermined size, a plurality of LEDs are arranged at predetermined intervals, as shown in Figs. 4 and 5, the main board 31 having a predetermined length having a predetermined width vertically. ), and a pair of sub-boards 32 whose one end is connected to the upper and lower sides of the main board 31 and the other end is formed to be inclined at a predetermined angle.

At this time, the pair of sub-boards 32 are formed to be inclined at the same angle as the seating plate 13 of the main housing 10, and through this, the upper and lower ends of the sub-board 32 are in close contact with the seating plate 13 It is fixed through fastening members such as screws.

And the control device installed in the accommodation space of the housing body 11, the main board 31 and the sub board 32 are interconnected through a control line and a power line, through which the main board 31 and the sub board 32 ), the output operation is controlled.

As shown in Fig. 6 (a, b) through the LED matrix board 30 as described above, relatively large characters or figures are output through the main board 31 to guide the operation state of the facility, etc. A simple figure or color (e.g., red during operation, green when stopped) is output through the board 32, so that the LED matrix board 30 is relatively higher or lower than the main board 31. It makes it easy to recognize the contents of the graphic that is output through.

The light-transmitting cover 40 is installed to cover the other open side (front side) of the main housing 10 so that the graph output through the LED matrix board 30 is transmitted to the outside.

As shown in FIG. 1, the transparent cover 40 is made of a transparent material and is made of a square or rectangular plate, and a sealing member G is installed between the main housing 10 and the transparent cover 40. In this way, the internal airtightness of the housing body 11 is secured.

Through the configuration of the light-transmitting cover 40 as described above, the graphic output from the main board 31 side of the LED matrix board 30 is transmitted to the front side of the light-transmitting cover 40 and exposed to the outside as shown in FIG. Then, the graphic output from the sub-board 32 is transmitted to the upper and lower portions of the transparent cover 40 in a diagonal direction through the expansion part 11C to be exposed to the outside.

On the other hand, in the above, the light transmitting cover 40 is shown and described only as consisting of a square or rectangular plate having a predetermined width and length, but unlike this, as shown in FIG. 8, the upper and lower sides of the light transmitting cover 30 The inclined protrusion 41 protruding obliquely at a predetermined angle toward the subboard 32 of the LED matrix board 30 is formed, and a predetermined thickness is formed between the light transmitting cover 40 and the second flange 11B of the housing body 11. A light-transmitting block 43 having a rectangular cross-sectional shape is further installed, and a graphic (shape or color, etc.) output from the sub-board 32 through the inclined protrusion 41 and the light-transmitting block 43 is in the vertical direction. It can be configured to be delivered more reliably.

At this time, the inclined protrusion 41 induces the graphic output in the upper and lower diagonal directions through the sub-board 32 to be refracted toward the light-transmitting block 43. For this purpose, the inclined surface of the inclined protrusion 41 is opaque or translucent. Alternatively, the inclined surface of the inclined protrusion 41 may be painted in a color that is easy to reflect light.

In addition, a chrome-coated reflector 42 may be separately attached to the inclined surface of the inclined protrusion 41 as shown in FIG. 8.

In addition to this, the seating plate 13 and the sub-board 32 are shown and described as being inclined at a predetermined angle, but unlike this, the seating plate 13 and the sub-board 32 are light-transmitting, as shown in FIG. 9. It is configured by changing to an LED matrix board 30' formed parallel to the surface of the cover 40, and the graphic output from the sub-board 32 through the inclined protrusion 41 of the light-transmitting cover 40 is transmitted to the light-transmitting block 43 ) Can be changed to be refracted and transmitted.

The human body detection sensor 50 is installed on the front side of the housing body 11 to detect a moving object adjacent to the LED display board 1, and the control device provided inside the housing body 11 is a human body detection sensor 50 ) May be controlled to change the graphic output through the LED matrix board 30 or to change the graphic or color output through the sub-board 32 according to whether or not a moving object is detected.

Alternatively, the graphic output through the sub-board 32 may be controlled to blink for a predetermined time.

The LED display panel 1 of the present invention constructed as described above is installed adjacent to major facilities of various industrial facilities and is installed to inform the operator of the operation state of the facility. As shown in FIG. It is installed at predetermined intervals along the moving passage, so that when the operator moves along the moving passage to check the conveyor, whether or not the conveyor is in operation, etc. can be easily recognized through the LED billboard 1.

In addition, as the LED display panel 1 detected by the operator through the human body detection sensor 50 performs a different operation from the other adjacent LED display panel 1, it is possible to easily identify the location of the operator as well as the presence of the operator from the outside.

On the other hand, from the top, only the expansion part 11C is located above and below the housing body 11, and the subboard 32 of the LED matrix board 30 is located above and below the main board 31. Although shown and described, unlike this, expansion portions 11C are formed on both left and right sides of the housing body 11, and sub-boards 32 are formed on both left and right sides of the main board 31, respectively, The content of the graphic output from the side can be changed to make it easier to recognize.

As described above, in the present invention, the LED matrix board is divided into a main board and a sub board, the sub board is formed to be inclined at a predetermined angle with respect to the main board, and the upper and lower surfaces of the housing body are formed to be inclined to the outside, and output from the main board. The resulting graphic is checked at a similar height to the LED signboard, and the graphic output from the subboard is checked at a higher or lower position than the LED signboard, so that the graphic output through the LED signboard is delivered to the operator more reliably.

In the above, for the convenience of explanation, the drawings showing the preferred embodiments and the configurations shown in the drawings have been described with reference numerals and names, but this is an embodiment according to the present invention and is It is limited and the scope of the rights should not be interpreted, and the simple substitution with a configuration that has the same effect as a change to a variety of predictable shapes from the description of the invention is within the range that can be changed for easy implementation by a skilled person. You will see it extremely self-evident.
