Scatter plate outside pipe, the scatter plate is also rectangular, and the edge of the scatter plate and the edge of the substrate are neat
It is flat；
Accordingly every of the multiple LED light tube position punishment between every row in the ranks of the outer surface of the scatter plate
It is not provided with bar shaped groove, forms crisscross netted gap.
Further, the inner surface of the scatter plate is surrounded by the step that a circle is stretched out towards the substrate, described to dissipate
Plate is penetrated to support on the substrate by the step.
Further, multiple metal weldments are installed, the scatter plate is by welding the metal weldment on the step
It connects on the substrate and together with the substrate connection.
Further, multiple buckles are installed, the scatter plate is by opening up described be connected on the step
In in the bayonet on the substrate and together with the substrate connection.
Further, per in adjacent two blocks of LED unit plates, it is one of on the multiple metal weldment on another piece
The multiple interlaced distribution of metal weldment.
Further, per in adjacent two blocks of LED unit plates, it is one of on the multiple buckle and the institute on another piece
State multiple interlaced distributions of buckle.
Further, the inner surface of the scatter plate accordingly every of the multiple LED light tube in the ranks between every row
Position at be respectively equipped with bar shaped fin, form crisscross netted protrusion.
Further, the LED light tube emits RGB three primary colours lights.
Further, the cross section of the bar shaped groove is V-shaped.
Further, the inside in the scatter plate positioned at every bar shaped groove is embedded with bar shaped anti-dazzling screen.
Beneficial effects of the present invention are embodied in：
The present invention can carry out diffusing reflection to the light that LED light tube is sent out, avoid closely seeing by the way that scatter plate is arranged
The generation of dazzling phenomenon when seeing；Secondly, the present invention by the outer surface of scatter plate open up bar shaped groove formed it is crisscross
Grid groove, it is consistent with the gap extending direction that LED unit plate arranged vertically and horizontally splicing generation is crisscross, splicing gap can be made to exist
It is no longer apparent on entire LED display, form seamless illusion.
The bar shaped anti-dazzling screen that the present invention is embedded by being located at the inside of every bar shaped groove in scatter plate, can keep away
Exempt from two adjacent LEDs luminous tube and interfere with each other to cause display fuzzy, enhances the clarity of LED display.

Specific implementation mode
The present invention will be described in detail below with reference to the accompanying drawings and embodiments.It should be noted that in the feelings not conflicted
Under condition, the features in the embodiments and the embodiments of the present application can be combined with each other.
Referring to Fig. 1, Fig. 2, Fig. 4 and Fig. 6.
The LED display that the present invention can be used closely is spliced to form, institute by polylith LED unit plate 10 arranged vertically and horizontally
It includes rectangular substrate 101 and the multiple LED hairs arranged vertically and horizontally being arranged on the substrate 101 to state LED unit plate 10
Light pipe 102, the LED unit plate 10 further include the scatter plate 103 being covered in outside the multiple LED light tube 102, the scattering
Plate 103 is also rectangular, and the edge of the scatter plate 103 is flushed with the edge of the substrate 101；
Corresponding every of the multiple LED light tube 102 in the ranks position between every row in the outer surface of the scatter plate 103
The place of setting has bar shaped groove 1031, forms crisscross netted gap.
Here " in length and breadth " indicates the direction consistent with the long wide direction of substrate." in the ranks " and " between row " adjacent rows are indicated
Two region between row LED light tube and.
Above-mentioned scatter plate refers to the plate that the emergent ray of LED point light source can be scattered to processing, principle such as Fig. 7 institutes
Show, can make the light that LED light point is sent out no longer dazzling in this way, scattering degree is known as mist degree, specifically may be used with one
The material for determining mist degree is made, and either uses the light-transmitting plate coated scattering coating or stick scattering film.
The present invention is improved on existing LED unit plate, by the way that scatter plate is arranged, can be sent out to LED light tube
Light is scattered, the generation of dazzling phenomenon when avoiding closely watching；Secondly, the present invention is opened by the outer surface in scatter plate
If bar shaped groove forms crisscross netted gap, the crisscross seam with LED unit plate arranged vertically and horizontally splicing generation
Gap (substrate is with substrate before and between scatter plate and scatter plate) extending direction is consistent, and splicing gap can be made aobvious in entire LED
It is no longer apparent in display screen, form seamless illusion.
In one embodiment, the cross section of the bar shaped groove 1031 is V-shaped.In implementing the present invention, it may, invention
People has found, designs in this way, it is more preferable to form seamless artefact effects." V-arrangement " described here does not imply that shape strictly alike V, " V

The inner surface of the scatter plate is not contacted with the multiple LED light tube, can generate pressure to LED light tube to avoid scatter plate
Power, to prevent LED light tube from damaging.
In one embodiment, referring to Fig. 2, multiple metal weldments 104, the scatter plate are installed on the step 1032
103 are linked together by the metal weldment 104 is welded on the substrate 101 with the substrate 101.This connection
Mode, be easy implement, be connected firmly, as long as and pad is melted, scatter plate can be removed, LED easy to repair shine
Pipe.
In one embodiment, referring to Fig. 3, multiple buckles 105 are installed on the step 1032, the scatter plate 103 is logical
It crosses and the buckle 105 is connected in the bayonet being opened on the substrate 101 and is linked together with the substrate 101.This
Kind connection type, it is same to be easy to implement, and can buckle firmly be removed, so that scatter plate be removed, LED easy to repair shines
Pipe.
In one embodiment, per in adjacent two blocks of LED unit plates, it is one of on the multiple metal weldment 104 with
104 interlaced distribution of the multiple metal weldment on another piece.
In one embodiment, per in adjacent two blocks of LED unit plates, it is one of on the multiple buckle 105 with it is another
105 interlaced distribution of the multiple buckle on block.
Above-mentioned design is in order to which the tie point of the scatter plate and substrate that make adjacent two blocks of LED unit plates is interlaced, in this way
Space utilization is more reasonable.
In one embodiment, referring to Fig. 2 and Fig. 5, the corresponding the multiple LED light tube of the inner surface of the scatter plate 103
Every of 102 in the ranks every row between position at be respectively equipped with bar shaped fin 1033, form crisscross netted protrusion.This
Sample designs, and on the one hand can be used for supporting scatter plate, on the other hand plays the role of reinforcement to the position for opening up strip groove, protects
Demonstrate,prove structural strength and stability.
In one embodiment, the LED light tube 102 emits RGB three primary colours lights.Full color LED display screen is formed, more
It is applicable in.
