In a kind of embodiment, in addition to:Acrylic board (not shown).
Acrylic board is arranged on the electric energy input port of receiving coil 10 and transmit coil 20 electric energy delivery outlet.Adjacent
Two acrylic boards are bonded to each other.
It is that is, defeated in upper and lower two LED boxes 1 setting acrylic board, the electric energy for being specifically located at receiving coil 10
Entrance and transmit coil 20 electric energy delivery outlet, so, when two LED boxes 1 are spliced, adjacent receiving coil 10 and transmission
There is acrylic board between coil 20, and two LED boxes 1 can mutually fit.
Preferably, the spacing distance of receiving coil 10 and transmit coil 20 is up to 10mm.
Because magnetic force width penetrates transmission electric energy, metal material interval can send out heat substantial amounts of, so being set in LED box 1 sub-
Gram force plate is spaced.Specifically, acrylic board is arranged between two coils, can play a part of protecting coil.Adjacent two
Open the spacing distance that the thickness being superimposed after acrylic board fitting is equal between adjacent receiving coil 10 and transmit coil 20.It is preferred that
, adjacent receiving coil 10 and transmit coil 20 are 10mm apart from maximum, i.e., adjacent receiving coil 10 and transmit coil 20
Distance range is 0-10mm.
For example, in a kind of embodiment, when there is no acrylic board between adjacent receiving coil 10 and transmit coil 20
When being spaced, distance is 0mm between adjacent receiving coil 10 and transmit coil 20, that is, two adjacent LEDs casing 1 it
Between it is seamless spliced.
In order to protect coil, LED display is radiated, set between adjacent receiving coil 10 and transmit coil 20
Put acrylic board to be spaced, several embodiments of illustrating below, to thickness and receiving coil 10 and the transmit coil of acrylic board
20 set the relation between distance to be illustrated, it is worthy of note that, it is only some preferred embodiments to illustrate below, not
The present invention is construed as limiting.
In a kind of embodiment, an acrylic board, every acrylic board are set respectively in two adjacent LED boxes 1
Thickness be 5mm, then accordingly, the interval between receiving coil 10 and transmit coil 20 in two adjacent LED boxes 1
10mm is arranged to, when two LED boxes 1 are spliced, it is possible to realize seamless spliced.
In further embodiments, an acrylic board is set respectively in two adjacent LED boxes 1, it is preferred that every
The thickness of acrylic board be 1.5mm, then the thickness that two acrylic boards are superimposed is 3mm, then accordingly, this adjacent two
3mm is set between receiving coil 10 and transmit coil 20 in LED box 1, so, two LED boxes 1 are spliced
When, it is possible to realize seamless spliced.
And for example, in further embodiments, an acrylic board is set respectively in two adjacent LED boxes 1, preferably
, the thickness of every acrylic board is 2.5mm, then the thickness of two acrylic board superpositions is 5mm, then accordingly, this is adjacent
5mm is set between receiving coil 10 and transmit coil 20 in two LED boxes 1, so, by two LED boxes 1
During splicing, it is possible to realize seamless spliced.
In the present invention, each LED box 1 is preferably dimensioned to be:Wide 500mm, high 500mm, thick 80mm.
Transmitting coil and receiving coil it is in the same size, be:Long 400mm, wide 70mm, high 15mm.
In a kind of embodiment, the area for sending control module 50 and receive and control module 60 is less than 150cm2.Preferably,
It can will send control module 50 and receive and control module 60 is arranged to PCB (printed circuit board, Printed Circuit
Board), size Control is within 150mm × 100mm.
In the present embodiment, the peak power of LED box 1 is 200W, but due to being actually needed Mixed cascading, therefore each transmission
Control module 50 and receive and control module 60 are arranged to support 3000W.
Embodiment two:
Please continue to refer to Fig. 1, the embodiment of the present invention provides a kind of LED display, including:As described in embodiment
LED display module 100, in addition to:Base 200;
