Abstract
The utility model discloses a surface cover of an SMD (surface mount device) LED display. The surface cover comprises a substrate, wherein a plurality of lenses integrally molded with the substrate are arranged on the substrate; the lenses are arranged in a dot-matrix manner, so that the lenses are in one-to-one correspondence with LED chips of the external SMD LED display in position; the lenses bulge to form cases covering the LED chips; and tops of the cases are basicallyspherical-arch-shaped or ellipsoidal-arch-shaped. According to the surface cover, shapes of lens sections are changed, and original flat shapes are canceled, so that reflection of sunlight is reduced, and the ornamental value is improved for viewers. The surface cover can be widely applied to outdoor SMD LED displays.
Description
Technical field
The utility model relates to the face shield of a kind of LED display, particularly LED display.
Background technology
LED display screen is a kind of display mode that forms, passes through to control semiconductor light-emitting-diode of being arranged by light emitting diode, adopt low-voltage turntable driving, generally formed by parts such as light emitting diode, PCB circuit board, control card, power supply, drain pan, face shield, casing, wire rods.LED display screen is divided into direct insertion and SMD conventionally; adopting surface mounted LED display screen is packaged into bonded LED lamp by light emitting diode paster conventionally; and face shield mainly plays effect fixing and protection light emitting diode; in prior art; in the panel of face shield, be provided with lens at the correspondence position of paster LED chip; be used for being socketed light emitting diode, play the effect of protection LED chip.But, with reference to Fig. 1, because existing lens top is to be all substantially plane, when demonstration out of doors, lens can directly flash back the sunlight, affect spectators' the experience of watching, and, because lens are compared with plate face projection, at protruding edge, having there is refraction in light, also can have influence on the visible angle of display screen.
Utility model content
The technical problems to be solved in the utility model is: a kind of LED display face shield is provided, reduces the direct reflection of light.
The solution that the utility model solves its technical matters is: a kind of patch type LED display screen face shield, comprise a substrate, on substrate, there are the multiple and integrated lens of substrate, described lens are dot matrix arranged, make the LED chip position on the position of lens and the surface mounted type LED display screen of peripheral hardware corresponding one by one, described lens convex to form the housing that covers described LED chip, and case top is ball arch or ellipsoid arch substantially.
As the further improvement of technique scheme, described case top section forms a round and smooth curve, and this curve is made up of the circular arc of 3 sections of decentraction, between 3 sections of circular arcs, seamlessly transits.
As the further improvement of technique scheme, the material of described lens is coloured transparent PC plate.
As the further improvement of technique scheme, described lens are equidistant points configuration arrangement in length and breadth.
The beneficial effects of the utility model are: the utility model, by changing the shape in lens cross section, has been cancelled tabular originally, thereby has reduced the reflection angle of sunlight, has improved spectators' sight.And because lens cross section is that rounding off is circular-arc, when light is outwards launched, can on the corner not launch obvious refraction, make the visible angle of display screen higher.
The utility model can be widely used on the face shield of outdoor surface mounted type LED display screen.
Brief description of the drawings
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described 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 is not paying under the prerequisite of creative work, can also obtain other design proposals and accompanying drawing according to these accompanying drawings.
Fig. 1 is lens schematic diagram of the prior art;
Fig. 2 is overall schematic of the present utility model;
Fig. 3 is partial enlarged drawing of the present utility model.
Embodiment
Below with reference to embodiment and accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is clearly and completely described, to understand fully the purpose of this utility model, feature and effect.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 embodiment that those skilled in the art obtains under the prerequisite of not paying creative work, all belong to the scope that the utility model is protected.In addition, all connection/annexations of mentioning in literary composition, not singly refer to that member directly joins, and refer to and can, according to concrete performance, connect auxiliary by adding or reducing, and form more excellent draw bail.Each technical characterictic in the invention, can combination of interactions under the prerequisite of not conflicting conflict.
With reference to Fig. 2～Fig. 3, a kind of patch type LED display screen face shield, comprise a substrate 1, on substrate 1, there are the multiple and integrated lens 2 of substrate 1, described lens 2 are dot matrix arranged, make the LED chip position on the position of lens 2 and the surface mounted type LED display screen of peripheral hardware corresponding one by one, described lens 2 convex to form the housing that covers described LED chip, and case top is ball arch or ellipsoid arch substantially.By changing the shape in lens cross section, cancel tabular originally, thereby reduced the reflection angle of sunlight, improve spectators' sight.
As the further improvement of technique scheme, described case top section forms a round and smooth curve, and this curve is made up of the circular arc of 3 sections of decentraction, between 3 sections of circular arcs, seamlessly transits.Lens 2 are owing to will covering LED chip, thus the lateral dimension of lens be there are certain requirements, simultaneously, in order to reach projection, also be to have dimensional requirement to the height of lens 2, so in order to meet the requirement of size simultaneously, lens of the present utility model cross section is made up of 3 sections of circular arcs.In addition,, in the situation that LED chip is of the required size, the cross section of lens can also be one section of semi arch, or para-curve circular arc.
As the further improvement of technique scheme, the material of described lens 2 is coloured transparent PC plate.
As the further improvement of technique scheme, described lens 2 are equidistant points configuration arrangement in length and breadth.
Above preferred embodiments 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 the modification that these are equal to or replacement are all included in the application's claim limited range.
