Detailed description of the invention

As Figure 1-3, Fig. 1 shows that the anti-tampering LED display module that this utility model provides cuts to specific embodiment Face figure, such as figure, described anti-tampering LED group is provided with base body 2 and mask body 1, base body 2 and the mutual clamping of mask body 1, in it Portion forms a cavity, and inside cavity is provided with light source body, and described light source body includes drives plate 4 and LED lamp bead 5, LED lamp bead 5 It is connected to above drives plate 4；Multiple LED lamp bead 5, LED it is provided with on the most described drives plate 4 The quantity of pearl 5 can be arranged the most voluntarily；It is additionally provided with casting glue 8 on described drives plate 4 and is used for fixing LED lamp bead 5, Ensure that this reflection-proof LED display module possesses certain impact resistance.

From Fig. 1 it can further be seen that described anti-tampering LED display module is additionally provided with lens jacket 6, the top of described lens jacket 6 Face is connected with described mask body 1, and the bottom surface of described lens jacket 6 is additionally provided with and described light source body lenticular body one to one.Fig. 2 is The schematic diagram of the anti-tampering LED display module mask body that this utility model embodiment provides, outside the most described lenticular body It is provided with first every body of light 10.The light that described light source body sends is put together by lenticular body, described first be enclosed in every body of light each Around lenticular body, by completely separated for each lenticular body, eliminate the interference of light of neighbouring light source, strengthen LED display module Identification effect.Described first is cylindrical structure every body of light 10, and each first extends to the LED lamp bead of correspondence every body of light 10 Below 5 luminous points, cover single led lamp bead 5 and the lenticular body of correspondence completely, it is ensured that between different LED lamp bead 5 and lenticular body Light will not interfere.

Being additionally provided with locating groove 12 from Fig. 2 it can also be seen that on the bottom surface of described mask body, described lens jacket passes through institute State locating groove 12 to be positioned on described mask body 1.

Fig. 3 is the anti-tampering LED display module lens layer schematic top plan view that this utility model embodiment provides.As figure can See and be additionally provided with second be arranged between described lenticular body on described lens jacket every body of light 11, described second every body of light 11 for running through The hollow out hyperbola groove-like structure of described lens jacket 6.Although the light under lens jacket bottom surface being separated by every body of light 10 by first From, but the light between lens jacket still may interfere, so also needing to arrange second every light on described lens jacket Body.Second is hyperbolic configuration every body of light, from the figure, it can be seen that each second has four faces every body of light, blocks four respectively The light that individual light source sends in respective direction, and every four second every body of light one group, respectively by a light source on four direction send out The light gone out blocks completely, and whole structure is attractive in appearance, and technique is simple.This specific embodiment obtains first by single injection-molded technology Obtaining lens jacket, then on the basis of lens jacket, injection mo(u)lding obtains face shield layer again, and when injection, the material of face shield layer is filled out Being charged into and fill up every body of light every body of light and by second into second, described face shield layer uses opaque dark pigment, can be at utmost Light within absorption lens layer.

It is seen also in fig. l that be additionally provided with water proof ring 3 and burr 9 on described base body 2, water proof ring 3 is one layer of rubber Circle, is arranged in the groove on base body 2, plays waterproof effect.

The effect arranging burr 9 is when this anti-tampering LED display module device mounted externally, such as caisson table During face, can be fitted tightly with waterproof box body outer surface by burr 9, to reach FCL waterproof requirement.

This programme provide anti-tampering LED display module be respectively provided with before and after lens every electro-optical device, serve by The light that each light source sends carries out the effect isolated；The light that each light source is sent will not disturb each other, increases Identification efficiency.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model Protection domain within.
