In general, the LED lamp tube of outdoor LED display screen is externally provided with mask, existing mask is planar structure, to outside
The reflection of light is not good enough, be easy to cause glare phenomenon, reduces the contrast of LED display, influences display effect.
Utility model content
One purpose of the utility model is to provide a kind of LED display mask, has the advantages that display effect is good.
The above-mentioned technical purpose of the utility model has the technical scheme that
A kind of LED display mask, comprising: panel offers on the panel several for the logical of mounted LED lamp bulb
Hole；It encloses and is set to the through-hole circumferentially and the light-blocking wall of the protrusion panel surface；And it is set to the described of the via top
On light-blocking wall, for forming the shading edge blocked in the via top.
By using above-mentioned technical proposal, after mask covers on LED board, the light-blocking wall that through-hole is circumferentially arranged can be right
Extraneous light formation is blocked, and the light that can be issued with LED lamp bead is contrasted, and improves the contrast of LED display entirety,
Enhance the display effect of LED display；Shading subtracts along for blocking the light source above LED display, especially sunlight
The glare phenomenon that weak LED display occurs, improves the display effect of LED display；LED display provided by the utility model
Mask is enhanced by the way that light-blocking wall is circumferentially arranged in a manner of blocking extraneous light and be contrasted with LED lamp bead in through-hole
The contrast of LED display, and the mode of shading light at the top of stopping is set on the light-blocking wall in top, it is aobvious to reduce LED
The glare phenomenon of display screen improves the display effect of LED display.
Further, the non-shading of the light-blocking wall is equipped with reflection wall along the periphery corral of side, described reflective
Extinction slot is formed between wall and the light-blocking wall.
By using above-mentioned technical proposal, after extraneous light is irradiated on LED display, light can be in the slot of extinction slot
It is reflected between bottom and cell wall, diffusing reflection occurs so as to cause light, and then effectively reduce influence of the light to LED light,
Promote the display effect of LED display.
Further, the side wall of the extinction slot is gradually spread out from slot bottom to notch in " V " type.
By using above-mentioned technical proposal, the cell wall of V-type expansion can enhance reflection of the light among extinction slot, in turn
The diffusing reflection for enhancing light, further increases the display effect of LED display.
Further, the arc-shaped transition in corner of the extinction slot.
By using above-mentioned technical proposal, the corner arc-shaped transition of extinction slot can effectively increase the surface area of extinction slot,
To enhance the diffusing reflection of light.
Further, it is separated between the adjacent reflection wall by groove.
By using above-mentioned technical proposal, the setting of groove can make extraneous light that diffusing reflection occur, and effectively reduce light
Influence to LED lamp bead enhances the display effect of LED display.
Further, reinforcing rib is equipped between the adjacent reflection wall in horizontal direction.
It is opened up to weaken influence of the extraneous light to LED display on the surface of panel by using above-mentioned technical proposal
Several grooves and extinction slot, so the intensity of panel is weakened, reinforcing rib can not influence groove and suction as far as possible
Under the premise of light slot effect, enhance the structural strength of mask.
Further, the inner circumferential of the through-hole of the panel circumferential direction is equipped with for abutting against with the LED lamp bead
Positioning column.
By using above-mentioned technical proposal, positioning column can be abutted against with LED lamp bead, to be pre-positioned to mask, just
Mask and LED board are installed in staff.
Further, the panel, which is gone into battle, shows several location holes, and the location hole plugs for the stud on LED board.
By using above-mentioned technical proposal, the cooperation of positioning column and the stud on LED can be pre-positioned mask, just
Mask and LED board are installed in staff.
The another object of the utility model is to provide a kind of LED display mask die, for manufacturing such as above-mentioned technology
The LED display mask referred in scheme, the above-mentioned purpose of the utility model are achieved through the following technical solutions:
A kind of LED display mask die, for manufacturing LED display mask as described above, comprising: cope plate,
The cope plate is equipped with upper impression and injection hole, and the upper impression is connected with the injection hole；Lower template, the lower template

When from the bottom plate, a thrust is provided for the push plate so that the push plate has to close to the bottom plate side moves
First spring of trend；Side is fixedly arranged on the bottom plate, and the other side is inserted in the second guide post in the push plate；And
Be sheathed in second guide post for when the push plate is far from the bottom plate, provide a pulling force for the push plate so that
The push plate has the second spring to the trend moved close to the bottom plate side.
By using above-mentioned technical proposal, when moving when lower template to the direction far from cope plate, push rod pushes push plate, with
Make thimble that LED display mask is pushed away lower impressions, elastic deformation occurs for the first spring and second spring at this time；Work as lower template
When being moved to the side where cope plate, and after push rod is separated with push plate, in the first spring and the work of second spring elastic force
Under, thimble resets, and by the way that the first spring and second spring are arranged in lower template, can weaken because of the first spring or second
Inaccurate influence is resetted after spring fatigue to thimble.
In conclusion the utility model has the following beneficial effects:
1, by the way that light-blocking wall is circumferentially arranged in a manner of blocking extraneous light and be contrasted with LED lamp bead in through-hole, increase
The strong contrast of LED display, and the mode of shading light at the top of stopping is set on the light-blocking wall in top, it reduces
The glare phenomenon of LED display improves the display effect of LED display；
2, after extraneous light is irradiated on LED display, light can occur between the slot bottom and cell wall of extinction slot
Reflection occurs diffusing reflection so as to cause light, and then effectively reduces influence of the light to LED light, promotes the display of LED display
Effect；
3, the cell wall of V-type expansion can enhance reflection of the light among extinction slot, and then enhance the diffusing reflection of light, into
The display effect of one step raising LED display；
4, by the way that the first spring and second spring are arranged in lower template, can weaken because of the first spring or second spring
Inaccurate influence is resetted after fatigue to thimble.
