Description

A kind of grid LED display

[technical field]

The utility model relates to the display technique field, especially relates to a kind of grid LED display.

[background technology]

LED display is issued instrument extensive application in daily life as a kind of information.Conventional LED display is on lighttight slab construction, is that LED forms a pixel by light emitting diode, and each pixel is formed cell board or the casing with pattern, Word message with a dot spacing arranged; Varying number cell board or casing are combined into the LED display of different area.Light emitting diode has primary colours such as redness, green, blueness, white respectively, display screen can be made up of as look a kind of LED luminous point of primary colours, also can form as look by the LED luminous point of any two or three primary colours, there are special driving circuit and control system to control the brightness of various primary colours in each pixel again, thereby demonstrate pictures such as coloury video, picture, literal.LED display has enough colors and brightness at present, almost can make big arbitrarily, indoor outer can the use.

Because the light emitting pixel of display screen all is arranged on the lighttight planar structure, display screen is restricted maybe in the application of some occasion can not have given play to better effect.Such as, outside the glass of building curtain wall or the large-area conventional LED display of interior installation can have a strong impact on the visual range of personnel in the daylighting of interior of building and the building, or the influence visual range of inwardly watching by the buildings outside; In addition, conventional LED display will be an inanimate blackboard at the state of quitting work, and spoil the fun very much.

In view of above drawback, be necessary to provide a kind of new grid LED display to overcome above-mentioned defective in fact.

[utility model content]

Fundamental purpose of the present utility model is to provide a kind of realization casing light, and easy to connect and light transmission can be carried out a kind of grid LED display of variation assembling well.

For achieving the above object, the utility model adopts following technical scheme: a kind of grid LED display, be assembled on the outside framework by a plurality of cell boards and make, each cell board has drain pan, cover, LED luminous point, LED control chip and operation circuit, wherein, drain pan is divided into several zones, in each zone, be provided with a plurality of first through holes of arranged at certain intervals, four jiaos of places at first through hole respectively are installed at least one LED luminous point, cover is provided with the circular hole that passes for the LED luminous point, and and the first through hole corresponding second through hole.

Described first and second hole size unanimity, and all be square shape, also be installed on quick lock on the side of described outside framework.Also be provided with some raised lines on the cover, adopt the encapsulating encapsulation between cover and the drain pan.

Compared to prior art, the utlity model has following advantage:

1. owing to have a large amount of through holes on the display screen,, use flexibly so the screen body is frivolous, favourable installation, wind resistance is better than conventional LED display when using out of doors, has improved security;

2. screen body ventilation and heat is good, helps the long-term work of LED and power supply;

3. the combined employing of outside framework is locked fast, makes installment work fast convenient;

4. has favorable waterproof property, the usable range of expansion grid LED screen.

[embodiment]

Please refer to Fig. 1 to shown in Figure 5, be the basic structure of the utility model preferred embodiment.A kind of grid LED display is assembled on the outside framework 20 by a plurality of cell boards 10 and makes, and each cell board 10 has drain pan 11, cover 12, LED luminous point 13, LED control chip (not shown) and operation circuit (not shown).

Please refer to shown in Figure 1, outside framework 20 is broadly divided into the rectangle framework 21 of four hollows, each cell board 10 is assembled in the described hollow, rectangular framework 21, the side of outside framework 20 is provided with quick lock (not shown), and lock is used for quick easily each outside framework 20 assembling and forms bigger grid LED display together fast.

Please refer to shown in Figure 2ly, the shape of drain pan 11 is roughly consistent with hollow, rectangular framework 21, and it is mainly used in carrying LED luminous point.Drain pan 11 is divided into four zones, is provided with in each zone at certain intervals that a plurality of first through hole, 111, the first through holes 111 of arranged roughly are square shape, and per three LED luminous points 13 are distributed in the Si Jiaochu of first through hole 111 as one group.

Cover 12 is roughly similar to the shape of drain pan 11, and it is assembled on the drain pan 11, can be used for more firm fixed L ED luminous point 13, also can stop extraneous steam, dust and other impurities to enter in addition, to prolong the serviceable life of grid LED screen.Cover 12 is provided with the circular hole 121 that passes for LED luminous point 13, and and first through hole, 111 corresponding second through hole 122.Second through hole 122 is consistent with first through hole 111 size, and all is square shape, after cover 12 and drain pan 11 make up, first and second through hole (111,122) over against.Cover 12 also be provided with some raised lines 123 in a lateral direction, raised line 123 is mainly used in and stops the interference of external light source to LED display, so that improve the effect that display screen shows.

During assembling, at first on drain pan 11, assign LED luminous point 13, be incorporated into component units body 10 on the drain pan 11 well with cover 12 and drain pan 11 are corresponding again, the LED luminous point 13 of the cell cube 10 that assembles just passes the circular hole 121 on the cover 12, and first, two through holes (111,122) over against, in order to make the assembling of cover and drain pan more firm, usually adopt the pattern of encapsulating encapsulation, said units body 10 is assembled in the outside framework 20 at last, the bigger grid LED display of assembling can rely on the above-mentioned outside framework that assembles 20 to lock fast and combine if desired.Because encapsulating between cover and the drain pan is so this grid LED display also has the performance of good waterproof.

During use, can be according to requirement of client, adjust the glow color of LED, in addition, can behind grid LED screen, install other light installations additional, first and second through hole (111,122) that the light that light installations after installing additional is sent penetrates the grid LED display mixes with the light that LED display is sent, and can realize more lighting effects.

A kind of grid LED display of the utility model, be not restricted to described in instructions and the embodiment, for the personnel of familiar field, can easily realize additional advantage and modification, therefore under the situation of the spirit and scope of the universal that does not deviate from claim and equivalency range and limited, the examples shown that the utility model is not limited to specific details, representational equipment and illustrates here and describe.
