Abstract:
1. A light chain comprising a plurality of light emitting diodes electrically connected to each other, each light emitting diode comprising: a light emitting diode chip having a first pole and a second pole; a packaging layer encapsulating the light emitting diode chip; a first electrode having an inner end received in the packaging layer and electrically connected to the first pole of the light emitting diode chip, and an outer end extending through the packaging layer to the outside; a second electrode having an inner end received in the packaging layer and electrically connected to the second pole of the light emitting diode chip, and an outer end extending through the packaging layer to the outside; and a third electrode extending through the packaging layer, the third electrode having a first outer end located at the outside of the packaging layer and a second outer end located at the outside of the packaging layer; wherein the outer end of the first electrode and the first outer end of the third electrode cooperatively form a first plug; the outer end of the second electrode and the second outer end of the third electrode cooperatively form a second plug; the first plug is configured to attach to a second plug of an adjacent light emitting diode.
