Abstract
Some embodiments of the disclosure provide a light emitting diode (LED) light string with an improved sealed waterproof structure. In some examples, a series-connecting wire is connected to a plurality of sealed waterproof lamp holders. In other examples, after a bulb shell is mounted, the interior of a lamp holder body is completely sealed, with a good waterproof effect. In further examples, there is a safety zone greater than 3 mm between a first contact zone and a second contact zone of the lamp holder electrically connected to the series-connecting wire, which may prevent short circuits caused by electric leakage of the series-connecting wire, with high safety.
