Abstract
The utility model discloses an LED screen plate comprising a printed circuit board and an LED lamp that is arranged on one surface of the printed circuit board and connected with the printed circuit board by a circuit, and the other surface of the printed circuit board is provided with a metal radiating plate in an insulated manner, thus reducing the power consumption of LEDs arranged in a unit area under the precondition of ensuring heat dissipation.
Description
Technical field
The utility model relates to a kind of LED screen board, relates in particular to the closely spaced LED screen board of a kind of P4.
Background technology
Present LED screen, require more and more higher, show more and more meticulouslyr, the spacing between each LED assembly is more and more littler, in general reaches little spacing P4 even less than the LED screen of P4 spacing, requirement to heat radiation is high especially, in general, the printed circuit board (PCB) one side that now matches with the LED lamp all is provided with the epoxy resin of insulation, in the process of LED operation, the heat that produces is by this epoxy resin conduction, and effect is not very desirable.Chinese patent application number is the heat abstractor of disclosed a kind of led light source in 200710201306.3 the open text, the heat radiation main body is provided with heat pipe receiver, a heat pipe is set on heat pipe receiver at least, the mode that adopts heat pipe heat radiation to combine with the metal material heat radiation, heat conduction and heat dispersion improve greatly.But this mode is not suitable for the heat radiation of closely spaced LED screen board, and in limited space, taking up room of heat pipe receiver is bigger, and cost is higher, is not suitable for large-scale popularization and is suitable for.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of little spacing LED screen board is provided, and can also reduce the dissipation power of the LED that arranges in the unit area under the prerequisite that guarantees heat radiation.
For achieving the above object, the utility model has adopted following technical proposals: this LED screen board, comprise printed circuit board (PCB) and be arranged at the LED lamp that this printed circuit board (PCB) is simultaneously gone up and link to each other with its circuit that described printed circuit board (PCB) another side insulation is provided with metallic heat radiating plate.
Described metallic heat radiating plate another side insulation is provided with circuit.
Described printed circuit board (PCB) is the single face circuit board.
Described printed circuit board (PCB) is a double-sided printed-circuit board.
Be provided with an insulation course between described metallic heat radiating plate and the printed circuit board (PCB).
Described printed circuit board (PCB) is a multilayer circuit board.
Be provided with through hole not influencing the P.e.c. place on the described LED screen board, this through hole is worn
Saturating metallic heat radiating plate, up/down perforation.
Described metallic heat radiating plate is an aluminium sheet.
By technique scheme, thereby the heat that LED is produced transmits by metallic heat radiating plate, but also can conduct heat by being added with through hole, and radiating effect is better.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model LED screen board.
Fig. 2 is the utility model LED screen board second embodiment synoptic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is made further instruction.
As shown in Figure 1, this LED screen board, comprise the metallic heat radiating plate 1 of aluminum metal, two-sided single-layer printed circuit plate 2 and LED lamp 3, described metallic heat radiating plate another side face is provided with circuit 5 by insulation course 4, the LED lamp is arranged on the surface of printed circuit board (PCB) and is electrical connected with printing electroplax road, is provided with the insulating radiation layer 6 in order to insulating radiation between printed circuit board (PCB) and heat dissipation metal substrate.
As Fig. 2 is second kind of specific embodiment of the utility model, difference between itself and first specific embodiment is, the LED screen board of the described LED of setting lamp 3 is provided with the through hole 7 that does not influence P.e.c. on the printed circuit board (PCB) 2, this through hole penetrating metal heat sink 8, up/down perforation.
Compared with prior art, thereby the heat that LED is produced transmits by metallic heat radiating plate, but also can conduct heat by being added with through hole, and radiating effect is better.
