Scape is extremely wide, reliable just towards more high brightness, more high weather resistance, luminous density higher, uniformity of luminance higher
Property, panchromaticization direction are developed.And LED display is also because it can arbitrarily extend, and realize seamless spliced, the luminous flux attenuation slow life-span
Long the advantages of and be widely used in stadiums, business application, bank, card Securities, postal service, harbour, market, station, postal service, electricity
News, office, monitoring, school, dining room, hotel, amusement, etc. different outdoor locations advertising.
The inner heat generating components of LED display are more, and major heat producing components have LED chip, driving chip and power supply electricity
Source etc., therefore it is particularly necessary to carry out heat dissipation design to LED display.But, existing radiating mode not only complex structure, and
It is relatively costly.
Utility model content
Therefore, it is right the utility model proposes a kind of LED display with radiating structure for above-mentioned problem
The structure of existing LED display is improved, and makes its not only good heat dissipation effect, and with low cost.
In order to solve the above-mentioned technical problem, the technical scheme that the utility model is used is that one kind has heat sinking knot
The LED display of structure, including circuit board and the heat radiation rack of circuit board bottom is fixed on, several battle arrays are provided with above circuit board
Arrange the LED element of arrangement；The heat radiation rack includes the central area of fixing circuit board and the network structure around central area,
Wherein, for dustproof and waterproof, the central area of fixing circuit board is the tabular without slotted eye, the network structure of heat radiation rack with it is solid
The central area for determining circuit board is flush arrangement.In addition, the bottom of the heat radiation rack（Away from the side of circuit board）One is provided with to lead
Hot plate, in order to further improve radiating effect, also has space, to facilitate heat-conducting plate and radiating between the heat-conducting plate and heat radiation rack
Divulged information between frame.Preferably, it is pasted with heat dissipation film near the side of heat radiation rack on the heat-conducting plate.
In order to improve the optical property of whole LED display, it is preferred that the LED element is ellipsoidal structure, is set thereon
There are green LED chip, red LED chips and blue LED die, green LED chip, red LED chips and blue LED die
Center is respectively positioned on the major axis of the ellipsoidal structure of LED element.
The utility model compared with prior art, several is formed by the network structure of heat radiation rack by such scheme
Ventilation slot, so, the heat that the component on circuit board and circuit board is produced when working can be by the network structure of heat radiation rack
Ventilation slot rapidly spreads out, and substantially improves existing radiator structure.In addition, the network structure and permanent circuit of heat radiation rack
The central area of plate is flush arrangement so that the structure of heat radiation rack refers to diminution and avoids each radiating groove from receiving hitting for external force
Damage is hit, long-lived advantage has also been further functioned as.In addition, the orientation of each LED chip of LED element is consistent, also
Further increase three uniformity of color rising angle of red, green, blue of display screen.The utility model simple structure, it is easy to
Realize, radiating effect is good, with good practicality.
