The utility model discloses produced beneficial effect for prior art does:

the utility model discloses a reduce row between the former traditional support to metal rib to 1/3 width or less by a wide margin, change traditional rib metal stuck point embedding plastic mode and for moulding plastics the plastic supporter connection between the formation LED support, through reasonable plastic supporter thickness and width, the plastic burr that cuts off the plastic supporter when can realizing the final separation < 0.1mm, guarantees the qualification rate of product. The metal demolding support ribs arranged above the plastic support body form upward deformation during cutting, demolding is facilitated, the narrow column-direction ribs are no longer used as support functions, but used as demolding support bars of the support in the injection molding process, and demolding is completed and the service is finished.

Through the utility model discloses, can improve the range density of LED frame, especially in the aspect of the super small LED encapsulation that shows the application, because horizontal supporter is in large quantity, metal frame area ratio is big, can greatly promote the range density of LED support after saving horizontal supporter to greatly promote encapsulation efficiency, reduce LED encapsulation cost. The plastic defect problem of the LED support body caused by the traditional extruding dislocation stripping mode of stripping materials can be avoided, and the failure risk caused by stress on the LED support body is reduced.
