Abstract

The utility model discloses an aluminum LED display screen module comprising an aluminum bottom case. The aluminum bottom case comprises a first bottom board and a second bottom board. The first bottom plate is provided with a plurality of hollows. The front side of an LED lamp panel is connected with a face cover. The back side of the LED lamp panel is an IC (integrated circuit) side which is embedded in the hollows. A thermally-conductive silicone sheet corresponding to the hollows is attached to the second bottom board. The first bottom board and the second bottom board are connected through module lock screws. The aluminum LED display screen module has the advantages that such problems as time-consuming and labor-consuming maintenance, poor radiating performance, proneness of a plastic bottom case to deformation, difficulty in levelness control and proneness in arching causing shadows in the prior art are solved, and the aluminum LED display screen module is simple in structure, low in production cost, free of screws for connecting the face cover, convenient to maintain, effective in radiating, high in production efficiency and the like.

Description

A kind of aluminum LED display module

Technical field

The utility model relates to the LED technology, is a kind of aluminum LED display module specifically.

Background technology

At present, be mainly the plastic cement face shield on the market, drain pan is the plastic cement drain pan, is fixed on the drain pan with key screw face shield and PCBA, screw quantity is more, the maintenance trouble, radiating effect is undesirable, and the plastic cement drain pan is yielding, the control of flatness difficulty or ease, simultaneously during locking face cover screw tension face shield, easily arch upward and cause shade, especially more obvious at little dot spacing.

The utility model content

The purpose of this utility model is to overcome the deficiency that above prior art exists, and provides that a kind of simple in structure, low cost, face shield exempt from that screw connects, easy to maintenance, good heat dissipation effect and the high aluminum LED display module of production efficiency.

In order to achieve the above object, the utility model is by the following technical solutions: a kind of aluminum LED display module, comprise the aluminum drain pan, the aluminum drain pan comprises first base plate and second base plate, offers some hollow outs position on first base plate, and the LED lamp plate is positive to be connected with face shield, LED lamp plate reverse side is the IC face, the IC face is embedded in the hollow out position, and the thermal conductive silicon film is affixed on second base plate with respect to the hollow out position, and first base plate is connected by locked mode group screw with second base plate.

Preferably, described face shield is the web-like silicon sheet rubber soft face mask that offers some LED hole, and the reverse side of face shield is brushed with one deck gum.

Preferably, described gum is the 3M double faced adhesive tape.

Preferably, described locked mode group screw comprises five screws, and five screws are distributed on first base plate.

Principle of work of the present utility model: a kind of aluminum LED display module, comprise the aluminum drain pan, the aluminum drain pan comprises first base plate and second base plate, offer some hollow outs position on first base plate, the LED lamp plate is positive to be connected with face shield, and LED lamp plate reverse side is the IC face, and the IC face is embedded in the hollow out position, the thermal conductive silicon film is affixed on second base plate with respect to the hollow out position, and first base plate is connected by locked mode group screw with second base plate.

The aluminum drain pan adopts the mould Sheet Metal Forming Technology, and flatness is very high, the heat of PCB, IC and LED, radiate by good heat is distributed of aluminium sheet, greatly reduce the temperature rise of LED display, improved stability and the thermal equilibrium of LED display, simultaneously, eliminate the lamp area shading.

When needing repairing, five screws that only need to remove the locked mode group just can keep in repair.

The utility model has following advantage and effect with respect to prior art:

1, the utility model has adopted and has comprised the aluminum drain pan, the aluminum drain pan comprises first base plate and second base plate, offer some hollow outs position on first base plate, the LED lamp plate is positive to be connected with face shield, LED lamp plate reverse side is the IC face, and the IC face is embedded in the hollow out position, and the thermal conductive silicon film is affixed on second base plate with respect to the hollow out position, first base plate is connected with the second base plate locked mode group screw, has that simple in structure, low cost, face shield exempt from that screw connects, characteristics such as easy to maintenance, good heat dissipation effect and production efficiency height.

2, the gum in the utility model is the 3M double faced adhesive tape, can realize exempting from screw and connect, and installation and maintenance are all very convenient.

3, the face shield in the utility model is the web-like silicon sheet rubber soft face mask that offers some LED hole, when 80 ℃ of high temperature, 40 ℃ of low temperature, does not have the shade that arches upward and produce, no color differnece.

4, the aluminum drain pan in the utility model can effectively transmit heat, is that radiating effect is better, and flatness is protected simultaneously.

5, second base plate in the utility model is detachable, easy to maintenance, need not to tear open first base plate.

6, the locked mode group screw in the utility model comprises five screws, and is convenient to disassembly.
