Mask.
Background technique
LED display is a kind of flat-panel monitor, is made of LED module panel small one by one, for showing text, figure
The equipment of the various information such as picture, video, video signal.With brightness is high, operating voltage is low, small power consumption, enlargement, service life are long,
The dramatic benefits such as impact resistance and performance are stable.The development prospect of LED is extremely wide, just towards more high brightness, more high weather resistance,
Higher luminous density, higher uniformity of luminance, reliability, panchromaticization direction are developed.LED display is widely applied, in body
Educate venue, business application, bank, card Securities, postal service, harbour, market, station, postal service, telecommunication, organ, monitoring, school, dining room,
It is used in the industries such as hotel, amusement.
Conventional LED display is made of bottom case, circuit board, mask, wherein mask material is usually PS (polystyrene
Plastics) be made of or similar macromolecule material passes through injection molding mode.When the temperature difference occur in surrounding enviroment or environment temperature occurs
When degree variation, it is easy to cause material temperature variation range larger, mask is easy to cause to deform, influence its normal use.Separately
Outside, bad environments under open-air conditions, conventional mask do not have water-proof function, may cause when used for a long time through rainwater immersion
LED element short circuit, to influence illumination effect.
Summary of the invention
For the deficiency in the presence of the prior art, the present invention provides a kind of novel LED display screen masks, to solve
It is easily-deformable by temperature change existing for the LED display mask of existing plastic material, it is easily damaged；Do not have waterproof function simultaneously
The problem of energy, internal LED element is easy moisture damage.
To achieve the above object, present invention employs the following technical solutions:
A kind of novel LED display screen mask, the mask including being close to the setting of LED baseplate irradiated side, the mask are side
The colourless transparent glass of shape, 1.5~3 times with a thickness of LED base plate thickness of the mask, the mask is close to LED bottom plate one
The edge of side is provided with several fixed columns, and the fixed column runs through the fixation hole being correspondingly arranged on LED bottom plate, and fixed column
Screw thread is equipped with across one end of LED bottom plate；Sealing strip, the sealing strip position are additionally provided between the mask and LED bottom plate
In mask edge and be folded between LED bottom plate and mask, by between its mask and LED bottom plate tighter gap fill, institute
Stating sealing strip is marine glue prepared material, and the both ends of sealing strip are respectively arranged with the sub-buckle and female thread of snap fastener.
Compared with the prior art, the invention has the following beneficial effects:
1, the present invention uses the mask of glass system to use as the mask of LED display, stable material quality, surrounding enviroment
There is the temperature difference or occur to be easy to cause material temperature variation range smaller when variation of ambient temperature, not will lead to mask and become
Shape thereby may be ensured that prolonged use；
2, sealing strip is additionally provided between mask of the invention and LED bottom plate, sealing strip can be with Enclosed mask and the bottom LED
Gap between plate, so that the effect of sealing is played, in addition mask itself is also that sealing is fluid-tight, therefore can completely cut off completely
The entrance of rainwater guarantees the drying of internal LED element, prolongs its service life.

In figure: mask 1, LED bottom plate 2, sealing strip 3, fixed column 4, clamp 11, card slot 12, holding groove 41.
Specific embodiment
The technical solution in the present invention is further illustrated with reference to the accompanying drawings and embodiments.
Embodiment:
As shown in Figs. 1-5, the invention proposes a kind of novel LED display screen masks 1, including are close to LED bottom plate 2 and shine
The mask 1 of side setting, wherein LED bottom plate 2 and mask 1 are rectangular, and its size is identical to which mutual cooperation connects into one
A entirety.Mask 1 is the tempered glass materials of colourless light transmission in the present embodiment, and raw material is handled by anti-stress, so that it is anti-
Impact strength and tensile strength greatly improve, and increase the reliability in use process.In addition, face used in the present invention
Cover 1 also have it is non-friable, after fragmentation formed the characteristic without acute angle particle, it is safer.
Wherein, 1.5~3 times with a thickness of 2 thickness of LED bottom plate of mask 1 are 2 times in the present embodiment.The mask 1 leans on
The edge of nearly 2 side of LED bottom plate is provided with several fixed columns 4, and the quantity of fixed column 4 can be 4 to 8, in the present embodiment
Only one is respectively set in the quadrangle of mask 1.The fixed column 4 runs through the fixation hole being correspondingly arranged on LED bottom plate 2, and solid
One end that fixed column 4 passes through LED bottom plate 2 is equipped with screw thread, to be fastened in LED bottom plate 2 other side attaching nut.It is preferred that
Scheme in, connected between fixed column 4 and mask 1 by viscose glue, and be provided with inside holding groove 41 at the top of fixed column 4, from
And viscose glue is stored in holding groove 41 and is sufficiently contacted with mask 1, the cross sectional shape of fixed column 4 is round or regular hexagon, this
It is regular hexagon in embodiment.
In the preferred scheme of the present embodiment, mask 1 is concave away from 2 side of LED bottom plate, and the concave is with mask 1
Middle part be symmetric points central symmetry.The light issued on LED bottom plate 2 can be diffused by the mask 1 of concave, thus
Allow LED lamplight to be dispersed into bigger angle, improves its using effect.
In further embodiment, sealing strip 3 is additionally provided between mask 1 and LED bottom plate 2, the sealing strip 3 is located at mask
1 edge is simultaneously folded between LED bottom plate 2 and mask 1, and the tighter gap between its mask 1 and LED bottom plate 2 is filled, described
Sealing strip 3 is marine glue prepared material, and the both ends of sealing strip 3 are respectively arranged with the sub-buckle and female thread of snap fastener.Sealing strip 3 can be with
Gap between Enclosed mask 1 and LED bottom plate 2, so that the effect of sealing is played, in addition mask 1 itself is also that sealing is waterproof
, therefore the entrance of rainwater can be completely cut off completely, guarantee the drying of internal LED element, prolongs its service life.
Preferably, mutually chimeric card slot 12 and clamp 11 are provided on two opposite sides of mask 1, the card slot 12 is V
Type groove, the pyrometric cone forming head of the clamp 11.By the cooperation of card slot 12 and clamp 11, multiple masks 1 can be cooperatively connected
On larger LED bottom plate 2, so that being completely embedded between mask 1, guarantee its degree of stability.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention
