Description

A kind of LED display face shield of high-contrast

Technical field

The utility model relates to a kind of LED display face shield of high-contrast.

Background technology

LED is much utilized to show the equipment of information, as the LED such as traffic lights, command lamp, LED billboard all require to have higher contrast under the irradiation of sunshine.Conventional way is that black made by the face shield in LED lamp module, forms darker background color, to improve contrast.But in face shield, contained pigment can because of decomposition, variable color under the long-time irradiation at high light, and final color shoals, and makes the contrast of LED display device decline.

Utility model content

The technical problems to be solved in the utility model is: the LED display face shield providing a kind of high-contrast, and it can improve the contrast of LED from structure.

The solution that the utility model solves its technical matters is:

A LED display face shield for high-contrast, comprises mask body, and mask body is provided with the through hole passed through for LED lamp bead, and the workplace of mask body is provided with a protruding light shielding part, and described light shielding part is for blocking external light.

Further as technique scheme, light shielding part comprises several three kinds of shading muscle for blocking external light be arranged in order side by side, is respectively the first shading muscle, end shading muscle, several middle shading muscle between the first shading muscle and end shading muscle.

Further as technique scheme, described shading muscle extends in the horizontal direction.

Further as technique scheme, the height of the first shading muscle and/or end shading muscle is greater than any one middle shading muscle.

Further as technique scheme, several middle shading muscle described, its height entirety on the direction of the first shading muscle terminad shading muscle increases progressively gradually.

Further as technique scheme, three kinds of shadings of light shielding part all have outside upper upper shading surface, outside under lower shading surface, upper shading surface is connected with lower shading surface and shape has angle, and makes three of light shielding part kinds of shadings all have xsect triangular in shape.

Further as technique scheme, the angle of the workplace of upper shading surface and mask body is greater than the angle of the workplace of lower shading surface and mask body.

The beneficial effects of the utility model are: mask body is provided with protruding light shielding part, protruding light shielding part can block external light, thus shade is manufactured in mask body, make LED lamp bead luminous under shade, make the utility model have higher contrast.The utility model is for improving the contrast of LED display device.

Accompanying drawing explanation

In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present utility model, instead of whole embodiment, and those skilled in the art, under the prerequisite not paying creative work, can also obtain other design proposals and accompanying drawing according to these accompanying drawings.

Fig. 1 is that schematic diagram is looked on a left side for the utility model embodiment;

Fig. 2 is the schematic front view of the utility model embodiment.

Embodiment

Be clearly and completely described below with reference to embodiment and the accompanying drawing technique effect to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.Obviously; described embodiment is a part of embodiment of the present utility model, instead of whole embodiment, based on embodiment of the present utility model; other embodiments that those skilled in the art obtains under the prerequisite not paying creative work, all belong to the scope of the utility model protection.In addition, all connection/annexations mentioned in literary composition, not singly refer to that component directly connects, and refer to and according to concrete performance, can connect auxiliary by adding or reducing, and form more excellent draw bail.Each technical characteristic in the invention, can combination of interactions under the prerequisite of not conflicting conflict.

See Fig. 1 to Fig. 2, this is an embodiment of the present utility model:

A kind of LED display face shield of high-contrast, comprise mask body 1, mask body 1 is provided with the through hole 2 passed through for LED lamp bead, the workplace of mask body 1 is provided with a protruding light shielding part, described light shielding part is for blocking external light, such LED lamp bead just can in shade, and under also namely darker environment, luminescence, makes the utility model have very high contrast.

Light shielding part comprises several three kinds of shading muscle for blocking external light be arranged in order side by side, is respectively the first shading muscle 31, end shading muscle 32, several middle shading muscle 33 between the first shading muscle 31 and end shading muscle 32.According to the height of the various shading muscle of adjustment, to adapt to different surround lightings.

Time out of doors, sunshine is the principal element causing the contrast of LED to decline, therefore is extended in the horizontal direction by shading muscle, to block the sunshine from top.

The height of the first shading muscle 31 is greater than any one middle shading muscle 33.So the first shading muscle 31 first can manufacture large stretch of shade, has at least shading muscle 33 in the middle of part under this shade, manufacture the shade of small pieces again, so just can better improve contrast of the present utility model.Like this be arranged on sunshine direct projection ground time especially obvious because sunshine just can block by the first shading muscle 31.

Consider that highly higher shading muscle is arranged side by side, its manufacture difficulty is high, the too high shading influential point of tendons of simultaneous altitude affects the display effect of LED, and when considering the oblique irradiation of sunshine, shade also can obliquely project, due to the existence of the first shading muscle 31, therefore multiple middle shading muscle 33, its height entirety on the direction of the first shading muscle 31 terminad shading muscle 32 increases progressively gradually.

Three kinds of shadings of light shielding part all have outside upper upper shading surface, outside under lower shading surface, upper shading surface is connected with lower shading surface and shape has angle, and makes three of light shielding part kinds of shadings all have xsect triangular in shape.Leg-of-mutton xsect can allow the better injection of light, also can not reduce the effective area using lamp of the present utility model.

The angle of the workplace of upper shading surface and mask body 1 is greater than the angle of the workplace of lower shading surface and mask body 1.Make shading surface can block the extraneous light injected from top very well like this, also can allow simultaneously and use light fixture of the present utility model to have good visible angle.

Above better embodiment of the present utility model is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
