Abstract: An LED light core structure, which has better mechanical strength and good heat dissipation effect and is able to 360-degree project light. The LED light core structure includes a substrate having at least two faces. The substrate is formed with at least one opening communicating the two faces. LEDs are disposed on at least one of the two faces of the substrate at the opening, whereby the light emitted from the LEDs disposed on one of the two faces of the substrate can be projected through the opening to the opposite face of the substrate. Accordingly, the substrate can be made of metal material, whereby the substrate is unlikely to crack so that the ratio of good products is increased and the substrate can provide excellent heat dissipation effect for the LEDs. The conventional wolfram filament electrodes can be directly replaced with the LED light core structure.
