Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light emitting display panel in which a large number of light emitting diode lamps are assembled to form a collective light emitting lamp, and a plurality of the collective light emitting lamps are mounted side by side on a support panel. , A device for mounting each of the collective light-emitting lamps on the support panel.

[0002]

2. Description of the Related Art Generally, in this type of light emitting display panel, as shown in FIGS. 4 and 5, for example, a substrate 3 is fixed in a cylindrical case 2 having a diameter of about 30 mm or 50 mm.
By mounting a large number of light emitting diode lamps 4 on the substrate 3 side by side in the vertical and horizontal directions, a collective light emitting lamp 1 is constructed, and a plurality of the collective light emitting lamps 1 are attached to a building or the like. Pitch P on the front of 5
Are mounted side by side at intervals of, and any of the collective light emitting lamps 1 is lighted.

When the collective type light-emitting lamp 1 is attached to the support panel 5, conventionally, as shown in FIG. 5, a boss portion 7 having a female screw hole 6 is provided on the back side of the cylindrical case 2. Is integrally formed, and the mounting bolt 8 inserted so as to be screwed into the female screw hole 6 in the boss portion 7 is tightened from the back surface side of the support panel 5, or as shown in FIG. In a collective type light emitting lamp 1a having a large number of light emitting diode lamps 4a mounted in a cylindrical case 2a, at least a pair of left and right mounting pieces 2a 'are integrally formed on the outer peripheral surface of the cylindrical case 2a. Then, each of the mounting pieces 2a 'is configured to be fastened to the support panel 5a by a mounting bolt 8a screwed to the support panel 5a.

[0004]

However, as in the former case, the collective type light-emitting lamp 1 is attached to the support panel 5 by the attachment bolts 8 inserted from the rear surface of the support panel 5. In this case, since there are no protrusions on the outer peripheral surface of the tubular case 2, the pitch interval P between the collective light emitting lamps 1 can be narrowed to achieve the miniaturization of the light emitting display panel. On the other hand, it is necessary to mount and dismount the collective light-emitting lamps 1 on and from the support panel 5 from the back side of the support panel 5, so that each of the collective panels should be assembled with the support panel 5 mounted on a building or the like. It is extremely difficult or impossible to mount or remove the type light emitting lamp 1, and it takes a lot of time to replace, check and repair the collective type light emitting lamp 1. Was Tsu.

On the other hand, like the latter, mounting pieces 2a 'are integrally formed on the outer peripheral surface of the cylindrical case 2a of the collective light-emitting lamp 1a, and the mounting pieces 2a' are mounted on the mounting bolts 8a. In the configuration of fastening the support panel 5a to the support panel 5a, the mounting and dismounting of each collective light emitting lamp 1a with respect to the support panel 5a is performed by the support panel 5a.
However, since the mounting piece 2a 'projects from the outer peripheral surface of the cylindrical case 2a, the pitch interval P between the collective light emitting lamps 1a must be widened. Therefore, there is a problem in that the light emitting display panel becomes large.

SUMMARY OF THE INVENTION The present invention has a technical object to provide a mounting device capable of solving the above-mentioned conventional problems.

[0007]

In order to achieve this technical object, the present invention provides a "collective light-emitting lamp in which a large number of light-emitting diode lamps are mounted side by side on a substrate fixed in a cylindrical case, In a light emitting display panel in which a plurality of the collective type light emitting lamps are mounted side by side on a support panel, a bolt hole penetrating from the front surface of the substrate toward the rear surface side of the cylindrical case is formed, and the bolt hole is formed. The mounting bolt is inserted from the front side such that the tip of the mounting bolt is screwed into the female screw hole formed in the support panel. "

[0008]

[Operation] By configuring in this way, mounting and dismounting of each collective type light-emitting lamp with respect to the support panel,
Since it can be done by screwing in and loosening the mounting bolt from the front side, it is extremely easy to install and remove each collective lamp with the support panel still attached to the building. You can do it.

Moreover, by mounting each collective light emitting lamp on the support panel in the cylindrical case of the collective light emitting lamp, the pitch interval between the collective light emitting lamps can be narrowed. Of.

[0010]

Therefore, according to the present invention, the number of steps required for replacement, inspection and repair of each collective type light emitting lamp mounted on the support panel leads to an increase in the size of the light emitting display panel and a decrease in luminous intensity. It has the effect that it can be significantly reduced.
