For example, the waterproof protective layer is applied to the front surface of the first circuit board 12 with a predetermined thickness after the first circuit board 12 and the second circuit board 13 are assembled from the front opening of the light emitting module cover 17. The electrical connection part between the LED element 11 and the LED element 11 is protected, and the gap between the first circuit board 12 and the light emitting module cover 17 is filled to ensure the waterproof property on the front side of the LED light emitting module 10. . Such a waterproof protective layer initially has fluidity that can be applied, and can be formed using a synthetic resin material such as urethane that is cured after application to become rubbery elastic.

Next, the coupling block 20 that couples the LED light emitting modules 10 will be described in detail with reference to FIGS. 3 and 4.

The coupling block 20 closes the connector opening 17a and couples the adjacent LED light emitting modules 10 to each other, and the first connection connector 22 connected to the output connector 15 of one adjacent LED light emitting module 10. And the second connection connector 23 connected to the input connector 14 of the other adjacent LED light emitting module 10 and the first connection connector 22 and the second connection connector 23 which are arranged inside the coupling block main body 21 and electrically And a connector connecting portion 24 to be connected.

The coupling block main body 21 has a front cover 21b having an accommodation space 21a for the first connection connector 22, the second connection connector 23, and the connector connecting portion 24, and a rear cover 21c that covers the accommodation space 21a. When the LED light emitting modules 10 are coupled, the LED light emitting modules 10 are fitted so as to straddle the coupling concave portions 17b of both adjacent LED light emitting modules 10.

The first connection connector 22 and the second connection connector 23 are exposed to the front through a connector opening 21d formed on the front side of the coupling block body 21, and the coupling block 20 to the coupling recess 17b of the LED light emitting module 10 is exposed. Are automatically connected to the input connector 14 and the output connector 15 on the LED light emitting module 10 side according to the fitting.

The coupling block 20 configured in this way not only couples the LED light emitting modules 10 to each other but also closes the connector opening 17a of the light emitting module cover 17 and closes the output connector 15 and the input connector 14 of the adjacent LED light emitting modules 10. Are electrically connected to each other, so that the waterproofness of the electrical connection portion between the LED light emitting modules 10 can be ensured without housing a plurality of combined LED light emitting modules 10 in a case as in the prior art. It becomes possible.

As shown in FIG. 4, it is preferable that the coupling recess 17b has a guide projection 17c along the fitting direction of the coupling block 20, and the coupling block 20 has a guide groove 21e corresponding to the guide projection 17c. The reason is that not only the fitting operation of the coupling block 20 to the coupling recess 17b becomes easy, but also the positional deviation between the LED light emitting module 10 and the coupling block 20 after the fitting can be regulated.

The guide protrusion 17c can have various shapes, and the guide groove 21e may have a shape corresponding to the guide protrusion 17c. For example, when the LED light emitting modules 10 to be coupled are arranged side by side, the guide protrusion 17c of the present embodiment is arranged so as to be in parallel with the adjacent LED light emitting modules 10, and in this state, both LED light emitting modules are arranged. When the coupling block 20 is fitted into the ten coupling recesses 17b, the guide grooves 21e of the coupling block 20 engage with the guide protrusions 17c of both the LED light emitting modules 10 so as to draw them both. As a result, even if there is a slight gap or misalignment between the adjacent LED light emitting modules 10, this can be corrected during the fitting process of the coupling block 20.

When fitting the coupling block 20 into the coupling recess 17b of the LED light emitting module 10, it is preferable to install a waterproof rubber packing 25 between the LED light emitting module 10 and the coupling block 20, as shown in FIG. . In this way, the waterproof rubber packing 25 sandwiched between the light emitting module cover 17 and the coupling block main body 21 can reliably prevent water from entering from the

connector openings

17a and 21d.

Are preferably fastened and fixed. In this way, not only the coupling strength of the LED light emitting module 10 can be increased, but also the

connector openings

17a and 21d can be reliably closed to improve the waterproof performance.

According to the present embodiment configured as described, the coupling block 20 not only couples the LED light emitting modules 10 to each other, but also closes the connector opening 17a of the light emitting module cover 17 and closes the adjacent LED light emitting modules 10. Since the output connector 15 and the input connector 14 are electrically connected, an electrical connection portion between the LED light emitting modules 10 can be obtained without housing a plurality of combined LED light emitting modules 10 in a case as in the prior art. Waterproofness can be ensured. As a result, the conventional case for housing a plurality of coupled LED light emitting modules 10 is not required, and not only can the number of parts and the manufacturing cost be reduced, but also the overall weight can be reduced and the installation work can be simplified. become.

For example, as shown in FIG. 5, the outdoor assembly-type light-emitting display system 1 of the present invention can be applied to a signboard 200 that is conventionally installed. Specifically, the conventional billboard 200 and the internal lighting housed in the external frame 201 of the signboard 200 are removed, and then the conventional external frame 201 is used as it is to form the plurality of LED light emitting modules 10 and the coupling block 20.
