Overmolded extrudate structure and flexible led light strip

An overmolded extrudate structure comprises an extrudate body and a continuous encapsulation component that covers at least part of the surface of said extrudate body, wherein:

• said extrudate body includes two side plates and a bottom plate, which together form an accommodating space with an opening, said accommodating space is designed to accommodate and fix an LED light strip;
• said encapsulation component is configured to fit with said extrudate body, covering at least one of the outer and inner surfaces of said two side plates, as well as the top surface of said side plates;
• wherein said extrudate body is an integrally formed elongated extrudate body, alternatively, said extrudate body is assembled by splicing together a plurality of single-segment extrudates;
• wherein there are two encapsulation components and each encapsulation component closely adheres to and covers the outer surface and top surface of one side plate respectively;
• or
• each encapsulation component closely adheres to and covers the outer surface, top surface, and inner surface of one side plate respectively;
• and
• wherein each encapsulation component extends downward to form a retention part, which holds the outer surface of the corresponding bottom plate.
