Description
Technical field
The utility model relates to LED Display Technique field, relates in particular to the anti-reflective face shield of a kind of LED display.
Background technology
Continuous development along with the LED electronic product; LED display more and more receives people's favor; Compare with the common display screen, it has the following advantages: 1) frivolous: adopt light emitting diode as back light, do not need fluorescent tube; Therefore the thickness of LGP significantly reduces, and the thickness of whole group backlight can reduce about half; (2) power consumption reduces, and luminous efficiency is high, and flying power strengthens.CCFL in the past needs the series of voltage converter, and loss increases; LED self luminous efficiency is high.Generally speaking, can save the power consumption of traditional display screen about 40%, under the same electric weight situation, the lifting that directly brings flying power; (3) screen intensity is higher, and more uniformity, color representation power are strong, and for Color Range, the LED-backlit screen can easierly be accomplished wide look zone.(4) environmental protection: the LED-backlit screen does not conform to mercury, and mercury is harmful substance, can damage polluted source to human body; The life-span of LED-backlit is very long.
But how to guarantee that LED screen display quality in the sun just becomes the problem that the designer need consider; Through being set, the LED face shield solves this problem in the existing technology; The planar design at the face shield place of LED display commonly used is plane reflective surface or arc reflective surface, makes LED display under solar radiation, can be with the part sunlight reflected; Reach preferable display effect, but the reflecting effect of said structure is relatively poor.In order to reduce the reflecting effect of face shield, the following method of the normal employing of the like product of industry at present overcomes above-mentioned shortcoming, and its main settling mode is following:
1, take the mode of oil spout to weaken reflecting effect on the surface of LED display face shield, big but the mode of this oil spout receives the influence of environment, long-term use can make oil reservoir that face shield sprays drop and influence the luminous purpose of face shield;
2, the pure PC material of selecting black for use is as the face shield material, but because the quality of pure PC material is softer, can not play LED display protection and supporting role, can not be installed on the opposite and be covered with under the environment of certain degree of hardness demand;
3, select for use the PC+ glass fibre as the face shield material, though can improve its intensity, compressive property is relatively good, and the face shield surface is easy to generate the fine line and reflective of ripple, influences the visual effect of LED display.For these reasons, the structure of inventor's mask has been carried out further improvement.
The utility model content
The technical problem that the utility model mainly solves is that common the employing the residing plane of LED display face shield is plane reflective surface or arc reflective surface in the prior art; With this sunlight reflected that shines on the face shield is gone out; Make LED display reach preferable display effect; But said structure reflecting effect relatively poor, provide a kind of LED display to prevent reflective face shield.
For solving the problems of the technologies described above; The technical scheme that this new utility model adopts is: provide a kind of LED display to prevent reflective face shield, said face shield is a flat board, and said flat board is made up of a plurality of lamp bars; The end of said a plurality of lamp bars is connected to each other and forms whole portion; Be provided with ventilative groove between the adjacent said lamp bar, said lamp bar comprises a plurality of light-reflecting portion and a plurality of transmittance section, and said transmittance section is corresponding to the through hole that optical position is provided with that goes out of LED lamp pearl; The spacing position of adjacent LED lamp pearl is a light-reflecting portion, and said light-reflecting portion is provided with a plurality of convexities.
Wherein, even parallel being distributed on the said flat board of said lamp bar.
Wherein, the spacing between the adjacent said convexity is 1～2 millimeter.
Wherein, the thickness of said convexity is 0.3～0.5 millimeter.
Wherein, the cross section of said convexity is semicircle, and the diameter of said semi-cylindrical hill is 0.4～0.6 millimeter.
Wherein, said convexity is vertically installed in the light-reflecting portion of said lamp bar.
Wherein, also be provided with reinforcement between the lamp bar of said reflective face shield, the two ends of said reinforcement connect adjacent lamp bar.
Wherein, also be provided with screw in the whole portion of said reflective face shield.
The beneficial effect of the utility model is: being different from common the employing the residing plane of LED display face shield of prior art is plane reflective surface or arc reflective surface; With this sunlight reflected that shines on the face shield is gone out; Make LED display reach preferable display effect, but adopt said structure can not reach the reflecting effect and the display effect of expection.A kind of LED display of the utility model is prevented reflective face shield; Through a plurality of lamp bars are set on flat board; And light-reflecting portion and transmittance section be set on the lamp bar, transmittance section corresponding LED lamp pearl is provided with, can make light that LED display sends through the transmittance section on the lamp bar to external radiation; The point of the corresponding LED lamp of light-reflecting portion pearl can make the external world shine the light generation diffuse reflection of light-reflecting portion on the lamp bar apart from setting, and the interference that has stoped extraneous light that LED display is emitted beam effectively can reach preferable reflecting effect and display effect.To sum up, the utility model is simple in structure, and production cost is lower, and display effect is preferable, has preferable market prospects.
