Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a collective type L for displaying information.
Regarding ED lamp.

[0002]

2. Description of the Related Art In recent years, large-sized information display boards using LED lamps have come into use. This information display board is a combination of a plurality of LEDs as if it were one L
A large-sized screen is constructed by arranging a large number of LED lamps formed like an ED as a one-dot display element in a two-dimensional manner.

FIG. 2 is a sectional view of a portion where a conventional collective LED lamp is attached to an information display plate. In FIG. 2, a plurality of LEDs 2 are arranged inside the outer shell 1 of the collective LED lamp and arranged on the printed wiring board 3, and a resin 4 is injected and cured. A power cable 5 for lighting the LED 2 is connected to the printed wiring board 3 from a collective LED lamp mounting housing 6. A large number of collective LED lamp bodies 7 are two-dimensionally mounted on the collective LED lamp mounting housing 6 using such a mounting structure to form the information display plate shown in FIG.

Here, an insert nut 8 for mounting to the collective LED lamp mounting housing 6 is incorporated in the collective LED lamp main body 7, and a screw 9 is used from the inside of the collective LED lamp mounting housing 6. Connection is fixed. Here, in order to prevent water from entering around the power cable 5, the O-ring 11 is provided so that the connecting portion between the collective LED lamp body 7 and the collective LED lamp mounting housing 6 surrounds the periphery of the power cable lead-out hole 10. Sandwiched between.

[0005]

In the conventional collective LED lamp, when the collective LED lamp mounting housing 6 is mounted, the mounting surface is fixed while the collective LED lamp is fixed to the collective LED lamp mounting housing 6. Must be screwed from the back side of. Also, when replacing the collective LED lamp,
Since the screws had to be removed from the inside of the collective LED lamp mounting housing 6, it was difficult to install and remove the collective LED lamps.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a collective LED lamp which can be easily attached and detached from the outside of the collective LED lamp mounting housing.

[0007]

SUMMARY OF THE INVENTION According to the present invention, a collective LED lamp body comprises an LED display section and a support base for the LED display section, and first connecting means for attaching and detaching the LED display section to the support base. A second connection means for mounting the support base on the collective LED lamp mounting housing is provided.

[0008]

According to the present invention, with the above-described structure, the support base can be first attached to the collective type LED lamp mounting case from the outside of the mounting case, and the LED display section can be further attached to the support base. The collective LED lamp can be attached and detached only from the outside of the collective LED lamp mounting housing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. FIG. 1 shows a collective LED lamp 2 of the present invention.
2 is a cross-sectional view when 1 is attached to a collective LED lamp mounting housing 22. FIG. As shown in the figure, the collective LED lamp 2
1 is composed of an LED display unit 23 and a support base 24. Inside the LED display unit 23, a plurality of LEDs 2
The printed wiring board 26 on which 5 is mounted is fixed, and the waterproof resin 27 is cured. The support base 24 is made of an elastic material having an appropriate hardness, and the power cable lead-out hole 2 is provided on the contact surface between the support base 24 and the collective LED lamp mounting housing 22.
A rib 29 for the purpose of waterproofing 8 is provided. Here, since the support base 24 is made of an elastic material and the ribs 29 are provided, the conventional O-ring 11 is unnecessary. The support base 24 is screwed to the collective LED lamp mounting housing 22. At this time, the ribs 29 are pressed against each other, and a waterproof effect is obtained between the support base 24 and the collective LED lamp mounting housing 22. Supporting base 24 is a collective LED lamp mounting housing 2
After connecting to 2, the LED display unit 23 is mounted on the support base 24. The LED display unit 23 and the support base 24 are connected by pressure bonding to obtain a waterproof effect. Especially the support base 24
Since is an elastic body, parts such as an O-ring and a waterproof seal for waterproofing the connecting portion are unnecessary. Also,
A hook 30 provided on one of the LED display unit 23 and the support base 24 has a detachable structure.

As described above, the collective LE according to the embodiment of the present invention
According to the D lamp 21, the collective LED lamp mounting housing 2
All mounting work to 2 is a collective type LED lamp mounting housing 22
Since the work can be performed from the outside, the work can be facilitated and the number of steps can be significantly reduced as compared with the case where the simultaneous work from the outside and the inside of the collective type LED lamp mounting housing 22 according to the conventional method is required. it can. Specifically, first, in the mounting operation, the support base 24 is screwed to the collective LED lamp mounting housing 22 from the outside of the collective LED lamp mounting housing 22. Since this mounting work can be performed independently of the rear surface of the collective LED lamp mounting housing 22, it does not require an auxiliary worker on the rear surface, the work is easy, and the work can be performed only from the outside regardless of the size of the screen. It is possible. This feature is particularly important for the collective LED lamp, because the mounting place is outdoors and there are many high places.

The collective LED lamp 21 can be replaced from the outside of the collective LED lamp mounting housing 22 since the LED display section 23 and the support base 24 can be attached and detached. This can be replaced in a short time, and at the same time, it can be easily replaced even by an unfamiliar worker by attaching and detaching the light bulb from the socket.

[0012]

As described above, the present invention includes an LED display section,
Since the support base, the first connecting means for attaching / detaching the LED display unit to / from the support base, and the second connecting means for mounting the support base on the collective LED lamp mounting housing are combined, It is possible to provide a collective LED lamp which can be mounted on the collective LED lamp mounting housing from the outside of the collective LED lamp mounting housing, which improves workability and can significantly reduce the number of steps.
