Embodiment
The outdoor grid screen of composition graphs 1 to Fig. 5, this LED comprises casing 100, LED 200, pcb board 300 and protection drain pan 400.LED 200 is arranged on pcb board 300, and pcb board 300 is tightly connected with protection drain pan 400, and protection drain pan 400 pairs of pcb boards 300 protect.Pcb board 300 and protection drain pan 400 form minimum display unit module.Pcb board 300 and protection drain pan 400 are fixedly mounted in casing 100, and pcb board 300 leans on mutually with casing 100.
In this embodiment, casing 100 is sheet metal box body, one-body molded by monoblock sheet metal bending, and surface smoothness and consistance improve greatly, greatly reduces the mosaic of viewing area and the bad phenomenon such as picture is uneven.Casing 100 has display panel, and display panel offers multiple casing through-hole, and with weight reduction, penetrating light, alleviates blast when the outdoor use of large area.In further embodiment, casing 100 is integrally formed by 2.0mm standard aluminum panel numerical control punching.
Pcb board 300 is provided with the LED 200 of 32 × 16 quantity.Pcb board 300 adopts screw be connected with protection drain pan 400 and adopt lamp glue to play glue, realizes being tightly connected, and makes to protect effective protection that drain pan 400 realizes pcb board 300.Pcb board 300 offers multiple pcb board through-hole, with weight reduction, penetrating light, alleviates blast when the outdoor use of large area.Further, pcb board 300 is also provided with the control chip controlling LED 200.Pcb board 300 is provided with at least one positive and negative power supply circuit and signal control line road.
Protection drain pan 400 is plastic cement drain pan.Protection drain pan 400 is provided with multiple sky shade 410.Sky shade 410 through pcb board 300, and passes casing 100, is positioned at above LED 200, protects LED 200, prevents solar radiation and increases display comparison degree.Protection drain pan 400 offers drain pan through-hole, and with weight reduction, penetrating light, alleviates blast during the use of large area open air.Drain pan through-hole is arranged on above sky shade 410.Drain pan through-hole is arranged on above sky shade 410, and when human eye is looked up, the stop due to sky shade can not see that light spills, thus increases display comparison degree further.In further embodiment, be better penetrating light and alleviate blast, casing through-hole, pcb board through-hole and drain pan through-hole three communicate.
In addition, the outdoor grid screen of this LED also comprises control device 500.Control device 500 is installed on casing 100 back, for controlling LED 200.In this embodiment, control device 500 comprises power supply and system acceptance card.Power supply provides electric power to LED 200, and system acceptance card docking enters the signal that system sends over and processes, and carries out signal control to LED 200.
Further, the outdoor grid screen of this LED includes 4 groups of minimum display unit modules, namely comprises 4 pieces of pcb boards 300 and 4 pieces of protection drain pans 400.
The outdoor grid screen of this LED, pcb board 300 adopts lamp glue to play glue after adopting screw to be connected with protection drain pan 400 and seals, and both are fixedly mounted in casing 100 after being tightly connected.Protection drain pan 400 can protect pcb board 300, avoid pcb board 300 directly outside exposed, effectively prevent rainwater to the erosion of pcb board 300, prevent pcb board 300 corrosion and ageing damaged, thus the outdoor grid screen of LED can be used out of doors, not damaged, greatly strengthen the application of LED grid screen.Casing 100 is one-body molded by monoblock sheet metal bending, thus surface smoothness and consistance improve greatly, greatly reduces the mosaic of viewing area and the bad phenomenon such as picture is uneven.Casing 100, pcb board 300 and protection drain pan 400 offer casing through-hole, pcb board through-hole and drain pan through-hole respectively, thus weight reduction, penetrating light, alleviates blast greatly when the outdoor use of large area.Protection drain pan 400 is provided with sky shade 410, and sky shade 410 passes casing 100 and is positioned at above LED 200, protects LED 200, thus prevents solar radiation and increase display comparison degree.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
