Abstract
The utility model provides a kind of LED display mask, including mask, multiple polygonal-shaped openings with array-like structural arrangement are disposed on the mask, each edge of the polygonal-shaped openings, which is each formed in positive one end of the mask along the positive direction rearwardly of the mask, avoids notch for the light of increasing light launch angle.The utility model will be all formed as the notch of crescent shape at the top of each side wall of polygonal-shaped openings, thus increase luminous angular range and whole visible angle, and the influence to brightness reduces, so that the spectators of side also have preferable visual experience.Certain region can also be limited simultaneously and carries out sealing, to protect LED light source.
Description
Technical field
The utility model relates to LED display technical field, in particular to a kind of LED display mask.
Background technique
Outdoor LED display screen, it is necessary to ensure in certain distance, screen content, and visual range can be clearly indicated
Greatly, though side spectators it can be seen that.As shown in Figure 1, the mask side of the prior art be rectangle, bright light source when
It waits, side light-emitting angle is blocked, and the whole visible angle of such display screen becomes smaller, and not only has an impact to brightness, to side
Spectators visually experience also poor.
Utility model content
The utility model provides a kind of LED display mask, to solve the above technical problems.
To solve the above problems, the one aspect as the utility model, provides a kind of LED display mask, including
Mask is disposed with multiple polygonal-shaped openings with array-like structural arrangement, each edge of the polygonal-shaped openings on the mask
It is each formed with along the positive direction rearwardly of the mask for the increasing light angle of departure in positive one end of the mask
The light of degree avoids notch.
Preferably, the polygonal-shaped openings are square or rectangle.
Preferably, the profile of the light evacuation notch is arc-shaped.
Preferably, offer fixation hole on the mask, the fixed hole position on the mask wherein four it is adjacent
The overlapping vertex position of the polygonal-shaped openings.
Preferably, the overlapping vertex position of the two neighboring polygonal-shaped openings on the mask is higher than LED light source
Top surface.
Preferably, the back side of the mask is formed with chuck outstanding.
The utility model will be all formed as the notch of crescent shape at the top of each side wall of polygonal-shaped openings, thus increase hair
The angular range of light and whole visible angle, the influence to brightness reduce, so that the spectators of side also have preferable visual body
It tests.Certain region can also be limited simultaneously and carries out sealing, to protect LED light source.In addition, the lowest point that side-walls notch is recessed
Mask layer is not touched, still there is certain distance, it can be ensured that the intensity of wall surface.

Specific embodiment
The embodiments of the present invention are described in detail below in conjunction with attached drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
The one aspect of the utility model provides a kind of LED display mask, including mask 1, cloth on the mask 1
Be equipped with multiple polygonal-shaped openings 2 with array-like structural arrangement, each edges of the polygonal-shaped openings 2 the mask 1 just
The one end in face is each formed with along the positive direction rearwardly of the mask 1 and lacks for the light evacuation of increasing light launch angle
Mouth 3.Preferably, the profile of the light evacuation notch 3 is arc-shaped.
In the above-mentioned technical solutions, the utility model will be all formed as crescent shape at the top of each side wall of polygonal-shaped openings 2
Notch, thus increase luminous angular range and whole visible angle, the influence to brightness reduces, so that the spectators of side
Also there is preferable visual experience.Certain region can also be limited simultaneously and carries out sealing, to protect LED light source.In addition, side wall
Mask layer is not touched in notch recessed lowest point in place's, still has certain distance, it can be ensured that the intensity of wall surface.
Preferably, the polygonal-shaped openings 2 are square or rectangle.
Preferably, fixation hole 4 is offered on the mask 1, the fixation hole 4 is located at wherein four on the mask 1
The overlapping vertex position of the adjacent polygonal-shaped openings 2, fixation hole 4 with mould group for connecting.
Preferably, the overlapping vertex position of the two neighboring polygonal-shaped openings 2 on the mask 1 is higher than LED light source
Top surface, four angles that can be formed in this way can play protection supporting role.
Preferably, the back side of the mask 1 is formed with chuck 5 outstanding, is located at mask avris, when for fastening, mask
With the positioning of mould group.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
