Abstract:
1. A method for manufacturing LEDs, comprising: providing a substrate; forming circuit structures on the substrate, each of the circuit structures comprising a first metal layer on an upper surface of the substrate, a second metal layer on an bottom surface of the substrate, and a connecting section extending through the substrate and connecting the first metal layer with the second metal layer; cutting through each of the circuit structures along the connecting section thereof to form a first electrical connecting portion and a second electrical connecting portion separated and insulated from each other via a gap therebetween; arranging LED chips on the substrate, and electrically connecting each LED chip to the first electrical connecting portion and the second electrical connecting portion of one circuit structure; forming an encapsulation on the substrate to cover the LED chips, the encapsulation filling at least a part of the gap to obtain a semi-finished product, the gap being fully filled with the encapsulation, the separated first electrical connecting portion and second electrical connecting portion are connected together by the encapsulation; and cutting the semi-finished product through the substrate and the encapsulation along paths between the first electrical connecting portions and the second electrical connecting portions of neighboring circuit structures to form the LEDs; wherein the gap is fully filled with the encapsulation.
