Description

TECHNICAL FIELD

[0001] The utility model belongs to LED module technical field, specifically, it is waterproof type LED module. BACKGROUND

[0002] At present, the production process of the graphic type LED variable information sign on the road is as follows:

[0003] Firstly, the LED module (usually only with front waterproof function) is fixed on the inner waterproof sheet metal box body through the bolt and waterproof rubber ring. This step ensures the basic waterproof performance of the LED module, but also increases the overall assembly complexity.

[0004] Next, the inner waterproof sheet metal box body is firmly installed on the back of the outer aluminum plate of the road sign through the fixing feet and bolts.

[0005] This layer upon layer of fixing method, although it improves the stability of the structure, but also brings the weight problem that can not be ignored. Especially since the double-layer sheet metal box body design is adopted, the weight of the whole sign system becomes quite heavy, about 70 kg per square meter. This not only increases the difficulty of installation and transportation, but also puts forward higher requirements for the supporting structure.

[0006] In addition, since the graphic type LED variable information sign is usually designed as a special-shaped screen, that is, the distribution position of the LED module is customized according to the direction and pattern of the road, which leads to the shape of the inner waterproof sheet metal box body becoming various. Although this diversity meets the personalized needs, it greatly increases the processing difficulty and cost.

[0007] More troublesome is that when the LED module needs to be repaired or replaced, the worker often needs to remove the bolt first, and then the whole inner LED box body has to be removed from the aluminum plate (because the LED module is tightly clamped between the outer aluminum plate and the inner box body). This series of disassembly work not only is tedious and time-consuming, but also greatly reduces the maintenance efficiency. Therefore, it is necessary to improve. CONTENT OF THE UTILITY MODEL

[0008] In order to solve the above problems of the prior art, the utility model provides a waterproof type LED module, which is simple in structure, convenient to install and maintain, and high in practicability.

[0009] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0010] As an aspect of the utility model, a waterproof LED module is provided, which comprises: an LED module body and a waterproof unit, the waterproof unit is connected to the back of the LED module body, and the waterproof unit covers the wiring area of the LED module body;

[0011] A waterproof boss is formed around the wiring area of the LED module body; when the waterproof unit is connected to the LED module body, the waterproof unit cooperates with the waterproof boss;

[0012] The waterproof unit comprises a waterproof shell, the waterproof shell has an open part, and the open part cooperates with the waterproof boss; the open part extends outward around to form a mounting plate; when the waterproof unit is connected to the LED module body, the mounting plate and the back of the LED module body are connected by fasteners.

[0013] Optionally, the waterproof shell is provided with one or more threading grooves for the threading of the cable of the LED module body, and a waterproof ring is arranged between the threading groove and the corresponding cable.

[0014] Optionally, the mounting plate is provided with a plurality of mounting holes.

[0015] Optionally, the back of the LED module body is provided with a positioning column, and the mounting plate is provided with a positioning hole matched with the positioning column.

[0016] Optionally, the waterproof shell of each waterproof LED module is connected to the connecting rod by fasteners.

[0017] Optionally, a screw column is formed on the waterproof shell, and the connecting rod and the screw column are connected by fasteners.

[0018] Optionally, the screw hole of the screw column is a blind hole.

[0019] Optionally, a fixed connecting piece is further provided, and the connecting rod is connected to the outer aluminum plate through the fixed connecting piece.
