▎ 摘  要

(CN208191005-U) NOVELTY - The utility model claims a graphene reinforced heat-conducting metal PCB plate array for LED package, comprises a base plate of metal layer, a substrate insulating layer, copper sheet layer and graphene layer; said copper sheet layer comprises multiple LED units are located on the same plane; adjacent LED units are provided with a gap; the graphene layer comprises a plurality of graphene unit located in the same plane and opposite with the LED unit, between adjacent graphene unit provided with a gap, each graphene unit for mounting one LED chip. by setting the unit graphene, because graphene conductivity is very high, when the LED chip is mounted on the graphene unit, equivalent to the effective heat transfer of the substrate insulating layer area is enlarged. This can effectively reduce the heat transmission temperature between the LED chip and the substrate metal layer difference, so that the LED chip radiating effect is good; besides, copper heat conducting effect is better than the price of graphene is low, thus meeting the heat-conducting effect under the premise that the graphene combined with copper can relatively reduce the thickness of graphene. so as to reduce the cost of the PCB board. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a graphene strengthened heat-conduction metal PCB. LED chip (1) Substrate heat-insulation layer (4) Substrate metal layer (5) Graphene layer (6) Graphene layer comprises graphene units (61)
