Abstract
The utility model discloses a mask of an LED display screen, which comprises a panel, wherein the panel is provided with at least two rows of inclined surfaces, each row of the inclined surface is provided with a row of lamp holes. The at least two rows of inclined surfaces are adopted on the panel and a groove for separating is arranged between every two rows of inclined surfaces. External light beam irritates on the mask, and the inclined surfaces have a function of reflection. The mask effectively reduces the influence of the light beam on an LED lamp, and leads users to see the display screen more clearly, straightly and directly. The lamp holes in the panel are separated from each other with the grooves, wherein the grooves play a role in absorbing light. Therefore, the mask can better protrude each pixel point, and better play the video effect of the LED display screen.
Description
[technical field]
The utility model relates to a kind of optical devices, especially relates to a kind of LED display face shield.
[background technology]
The outdoor LED display screen in large-scale place generally is made up of a plurality of LED fluorescent tubes, is provided with face shield in the outside of these LED fluorescent tubes.The front of existing face shield is planar structure, and is good inadequately to the reflection of extraneous light, influences the viewing effect of LED display.
[utility model content]
Given this, be necessary to provide a kind of LED face shield of effective elimination extraneous light influence.
By the following technical solutions:
A kind of LED display face shield comprises panel, and described panel is provided with the curve slope of stepped arrangement, is laid with a bank light hole on every capable curve slope.
Preferably: adopt circular arc to connect between per two row curve slopes.
Preferably: the lamp hole on the described panel is at least two row, is provided with groove between every row or the two row lamp holes and separates.
Preferably: described panel is provided with the shutter perpendicular to described panel above described lamp hole.
Preferably: also comprise the base plate of being located at described panel below, correspondence is provided with through hole on the described base plate.
Preferably: be provided with groove between the adjacent curve slope, be provided with groove between the adjacent lamp hole.
Preferably: described base plate is made by the PC material, and described panel is that flexible material is made.
Preferably: described flexible material is 70% silica gel.
Preferably: described base plate and panel adopt the method for quadric injection mould moulding to make.
Preferably: described mask size is 160X160mm.
Adopt curve slope on the panel, when extraneous light was radiated on the face shield, curve slope played the diffuse reflection effect, effectively reduced the influence of light to the LED lamp, made us when watching display screen more clear, more direct seeing clearly.
Lamp hole on the panel in the ranks separates with groove, and groove plays absorption effects, can better give prominence to each pixel, and the LED display video effect is better brought into play.
Separate with groove between the lamp hole row on the panel, groove plays absorption effects.Can better give prominence to each pixel, the LED display video effect is better brought into play.
Panel size length is 160X160mm, and this length is difficult for producing flexural deformation.

Be specifically described below in conjunction with accompanying drawing.
[embodiment]
As shown in Figure 1, LED display face shield, base plate 100 that comprises and panel 200.Base plate 100 is that pure PC material is injection molded, evenly is laid with through hole 120 on it.
As shown in Figure 2, panel 200 is a soft material, as 70% silica gel material, and quadric injection mould moulding on base plate 100, synthetic LED display face shield.Correspondence is provided with LED lamp hole 220 on the panel 200, and LED lamp hole 220 is relative with through hole 120, is convenient to LED and exposes.
As Fig. 2, Fig. 3 and shown in Figure 5, on panel 200, be provided with the curve slope 240 of stepped arrangement, the middle part of every capable curve slope 240 is provided with row's (at least two) lamp hole 220.The LED lamp exposes by lamp hole 220, and 240 pairs of extraneous lights of curve slope produce diffuse reflection, effectively reduce the influence of light to the LED lamp, make us when watching display screen more clear, more direct seeing clearly.
All fluted 260 separate between every row or the per two row curve slopes 240, between every row or the per two row lamp holes 220.Groove 260 plays absorption effects, can better give prominence to each pixel, and the LED display video effect is better brought into play.Quadric injection mould adds man-hour, if face shield is blocked up, is easy to generate shrinking deformation during injection moulding, adopts groove 260 can reduce the kurtosis of curve slope 240 between adjacent curve slope 240, makes the wall thickness of face shield even, prevents shrinking deformation.
Above each LED lamp hole 220, be provided with the shutter 280 that vertically protrudes from panel 200.Shutter 280 is arc or linear, can block extraneous light, improves the brightness of LED lamp, can also prevent external force damaged in collision LED lamp.
Per four LED lamps can be formed a single pixel, and the pixel that single led display screen face shield comprises is preferably 8X8.Under the situation of the thickness of panel 200 permission, the highest point of curve slope 240 can be than higher, can be as shown in Figure 2 between the so adjacent curve slope 240, and fluted 260 layers separate between the per two row lamp holes 220 in the single pixel.Adopt cambered surface 230 to connect between the two row inclined-planes 240 in the single pixel.Cambered surface 230 can be carried out diffuse reflection to light equally, reduces the influence of light to the LED lamp, makes us when watching display screen more clear, more direct seeing clearly.
The face shield overall dimensions is preferably 160X160mm.If oversize, flexible distortion behind the injection molded.Face shield be installed on the LED display effect as shown in Figure 4.
Above-mentioned double-deck face shield can use special occasions such as sports ground out of doors.Panel 200 is a flexible material, can prevent that collision is to athletic damage.When 280 of shutters can prevent that the sportsman from colliding face shield to the damage of LED lamp.The face shield of the single layer structure that uses for conventional occasion is made by pure PC material, can use the detailed structure such as shutter 280, curve slope 240, groove 260 of aforementioned panel 200 equally.At this moment, the thickness of panel 200 can be big slightly, and the highest point of curve slope 240 can be than higher, can be as shown in Figure 2 between the so adjacent curve slope 240, and fluted 260 layers separate between the per two row lamp holes 220 in the single pixel.Adopt cambered surface 230 to connect between the two row inclined-planes 240 in the single pixel.Cambered surface 230 can be carried out diffuse reflection to light equally, reduces the influence of light to the LED lamp, makes us when watching display screen more clear, more direct seeing clearly.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
