Abstract

The utility model discloses an LED module with a draining function, which is characterized in that draining grooves are arranged on side walls of the LED module, distributed along the side walls thereof and communicated mutually. Strong magnets are arranged on a rear frame of the LED module, positions of the draining grooves on the side walls of the LED modules combined into the same display screen are consistent, and drain holes are arranged at the lower end of an integral fixing frame used for fixing the LED module. By aid of the draining grooves arranged on the LED module, water can be guided to the bottom of the display screen via the draining grooves and finally can be discharged from the lower side of the display screen via the drain holes after seeping into the display screen from the front surface. The LED module is simple in structure, convenient for production, low in cost and applicable to wide popularization in the field of electronic display screens.

Description

Led module with drain function

Technical field

The utility model relates to a kind of electrical screen led module, relates in particular to a kind of led module with drain function.

Background technology

Along with the development of society, high-tech electronic products such as large-scale advertisement screen, huge TV are also being changed along with the development of LED, use LED display and replace in the past lamp box type billboard and the huge TV of projection to become a kind of inevitable.LED display is fixed on the framework that designs by tens LED unit modules to the hundreds of piece and forms at present, wherein common installs and fixes in the led module back exactly, the back frame 2 of led module is provided with fixing threaded hole 5 and sealing strip 4 as depicted in figs. 1 and 2, when assembling, led module is emitted in the overall fixed framework 7, sealing strip 4 is pressed on the framework of overall fixed framework 7 and sees through through hole on the overall fixed framework 7 and cooperate with fixing threaded hole 5 led module is fixed in the overall fixed framework 7, so just LED wiring board 1 is sealed in the overall fixed framework 7 by gib screw 6.Because have O-ring seal to prevent to destroy circuit from the front water inlet around the led module, this method can prevent effectively that rainwater from entering.But, general electrical screen is all formed to hundreds of piece module by tens, setting height(from bottom) does not wait from several meters to tens meters, and the failure rate of present electrical screen is higher, if keep in repair, when changing module or other device (as power supply or control card etc.), whole electrical screen must be removed on ground and safeguard with the electrical screen that this method is made.Can consume a lot of manpower and materials like this.

Another, the back frame 2 that is fixed on led module as shown in Figure 3 and Figure 4 is provided with strong magnet piece 8, when mounted led module is placed on the framework of overall fixed framework 7, adsorb the suction that the fixedly iron bar 9 on the overall fixed frameworks 7 produces by strong magnet piece 8, make led module realize being fixed on the overall fixed framework 7, like this when certain led module breaks down, only need firmly the led module that breaks down to be extracted by instrument from the front of electrical screen, keep in repair then, it is time saving and energy saving not need that so whole electrical screen is unloaded maintenance.But such electrical screen does not possess the function of waterproof, even mounting process is very high, has the possibility of leaking yet, and causes electrical screen to be burnt owing to leaking, so can only use in special occasion.

A kind of like this to have the maintenance used convenient, and the new LED module with water-proof function is badly in need of being developed.

Summary of the invention

The utility model is at the proposition of above problem, and development uses maintenance convenient, and has the led module of drain function.The technological means that the utility model adopts is as follows:

A kind of led module with drain function is characterized in that the sidewall of described led module is provided with drain groove, and described drain groove is along the sidewall setting of led module, and the drain groove of each sidewall is connected.On frame behind the led module, be provided with the strong magnet piece.The position that is provided with drain groove on the sidewall of the led module of forming same display screen is consistent.Osculum is offered in lower end at the overall fixed framework of fixed L ED module.

Because this has on the led module of drain function drain groove is set, when the whole screen of assembling, only need on the overall fixed framework, to be provided with the iron railings bar, module is adsorbed on the iron railings bar by the strong magnet piece, when water is in display screen is infiltrated in the front, because the effect of drain groove, water flows to the below of display screen, discharges from screen body below osculum at last.Need not remove whole screen during with the display screen maintenance of this method assembling, thereby as long as corresponding module be taken out the maintenance internal components from positive.Manpower and materials have been saved in this way greatly, along with the widespread use of display screen will bring great economic benefit and social benefit.Because it is simple in structure, be convenient to produce, and cost is very cheap is suitable for extensive popularization.

Embodiment

Fig. 5 and the led module with drain function shown in Figure 6 are provided with drain groove 10 on the sidewall of led module, described drain groove 10 is along the sidewall setting of led module, and the drain groove 10 of each sidewall is connected.Be the concrete effect of the led module that further specifies this drain function, this enforcement is sharp to be that the fixed installation mode is that example describes (also can be applicable on other mounting means simultaneously) to utilize the strong magnet piece.When mounted led module is placed on the framework of overall fixed framework 7, is adsorbed on the fixedly iron bar 9 on the overall fixed framework 7, make led module realize being fixed on the overall fixed framework 7 by strong magnet piece 8.For guaranteeing the best of drainage effect, form the position consistency of the drain groove 10 that the sidewall of the led module of same display screen is provided with, and offer osculum (not looking among the figure) with its discharge in the lower end of the overall fixed framework 7 by fixed L ED module.

The above; it only is the preferable embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and inventive concept thereof, all should be encompassed within the protection domain of the present utility model.
