Abstract

The utility model discloses an outdoor LED (light-emitting diode) display screen. The LED display screen comprises an LED face mask and a PCB (printed circuit board) which are arranged in tandem, wherein a plurality of LED lamps arranged in rows and columns are welded on the PCB, and a plurality of through holes arranged in rows and columns for penetrating through the LED lamps are arranged on the LED face mask; protection plates extending along the row direction are respectively and convexly arranged on the outer surface of the LED face mask corresponding to the same side edge of each row of the through holes; and the LED lamps in the through holes at each row can be sheltered from an external intense light source by the sheltering function of the protection plates arranged at the upper sides of the LED lamps, particularly from the direct irradiation function of sunshine, and the mutual interference function among each row of the LED lamps can be further weakened due to the arrangement of the protection plates, so that the display definition of the LED display screen can be improved, therefore, the outdoor good display effect of the LED display screen can be guaranteed.

Description

A kind of outdoor LED display screen

Technical field

The utility model belongs to LED display technique field, specifically is meant a kind of outdoor LED display screen.

Background technology

Development along with the LED technology; The application of LED display also more and more widely; Especially outdoor display screen is widely used in public places miscellaneous such as station, harbour, airport, market, hospital, hotel, is used for functions such as display graphics, literal, letter and various animations as the one of which; The LED face shield and the PCB circuit board that are provided with before and after existing LED display generally comprises; Be welded with the LED lamp that several ranks are arranged on the PCB circuit board; Offer the perforation that several supply the LED lamp to wear on the corresponding LED face shield; In using thus, the light that the LED lamp of being lighted is sent is penetrated by the outside surface of LED face shield, to play display effect; Existing outdoor LED display screen generally all need be installed in the high-altitude of outdoor several meters even tens meters; Existing commonly used LED face shield, it is simple in structure, can receive the sunlight or the direct irradiation of other intense light source on every side in the use unavoidably; Thereby directly disturbed the display effect of LED display; In addition, do not take safeguard procedures that phase mutual interference defective also can take place between each row LED lamp that said ranks are arranged, influenced the sharpness of outdoor LED display screen demonstration etc. thus.

In view of this, the present invention is directed to existing outdoor LED display screen problem and further investigate, this case produces thus.

The utility model content

The purpose of the utility model is to provide a kind of outdoor LED display screen, its overcome that outdoor LED display screen in the prior art is subject to that extraneous intense light source irradiation is disturbed and self LED lamp between interfere with each other and influence the defective of display effect.

In order to reach above-mentioned purpose, the solution of the utility model is:

A kind of outdoor LED display screen, LED face shield and PCB circuit board that it is provided with before and after comprising are welded with the LED lamp that several ranks are arranged on this PCB circuit board, offer several on the corresponding above-mentioned LED face shield and supply the perforation that ranks are arranged that is that above-mentioned LED lamp wears; The same side place of the above-mentioned perforation of corresponding each row convexes with one respectively and follows to the protective shield that extends on the outside surface of above-mentioned LED face shield.

Above-mentioned protective shield is wavy, each corresponding setting in outer convex arc section that above-mentioned perforation is corresponding with this wavy protective shield respectively.

After adopting such scheme; A kind of outdoor LED display screen of the utility model; The same side place of its above-mentioned perforation of corresponding each row on the outside surface of above-mentioned LED face shield convexes with one respectively and follows to the protective shield that extends, and places for erectting during LED display uses, and makes the corresponding respectively upper side edge that is positioned at above-mentioned each eleven punch 11 of each protective shield; LED lamp in every eleven punch 11 is by the bridging effect of the protective shield of its upside; Just can avoid the direct irradiation effect of extraneous intense light source, particularly sunshine, and the setting of protective shield can also be played the effect that interferes with each other that weakens between each row LED lamp; Promoted the sharpness that LED display shows thus, so this novel outdoor LED display screen has guaranteed its excellent out of doors effect that shows.

Label declaration

1 perforation 11 of LED face shield

Protective shield 12 outer convex arc sections 121

PCB circuit board 2 LED lamps 21

Embodiment

In order further to explain the technical scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.

Be depicted as a kind of outdoor LED display screen of the utility model like Fig. 1-3, the LED face shield 1 and PCB circuit board 2 that are provided with before and after it comprises; Referring to shown in Figure 2, be welded with the LED lamp 21 that several ranks are arranged on the PCB circuit board 2, LED face shield 1 is made of plastics, and correspondence offers several and supplies the perforation 11 that ranks are arranged that is that LED lamp 21 wears on it.

The utility model main innovate point is, on the outside surface of LED face shield 1, the same side place of corresponding each eleven punch 11 11 convexes with one respectively and follow to the protective shield 12 that extends; During using, places outdoor LED display screen for erectting; Specifically vertically place with the corresponding respectively mode that is positioned at the upper side edge of each eleven punch 11 11 of said each protective shield 12; LED lamp 21 in then every eleven punch 11 11 is by the bridging effect of the protective shield 12 of its upside; Just can avoid the direct irradiation effect of extraneous intense light source, particularly sunshine, and the setting of protective shield 12 can also be played the effect that interferes with each other that weakens between each row LED lamp 21; This novel outdoor LED display screen promoted the sharpness that LED display shows thus, so can guarantee the display effect that it is excellent out of doors.

Said protective shield 12, its height is decided according to actual conditions, and preferably, its height should be a little more than the height of above-mentioned LED lamp 21 outstanding LED face shields 1, and the setting of protective shield 12 has not only played preferable shield lights effect, but also has the effect of keeping off the rain; Further; As shown in Figure 2; Said protective shield 12 is wavy; Each outer convex arc section 121 corresponding setting that said perforation 11 is corresponding with this wavy protective shield 12 respectively, this kind mode be provided be by the wave curved surface to external world the preferable reflex of light come further to weaken of the influence of extraneous light, beholder's various information that just can more directly receive display screen clearly again and brought then to LED lamp 21.

Product form of the foregoing description and graphic and non-limiting the utility model and style, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.

Claims
