A parallel-type LED light string includes LED units connected in parallel to form a light string, the LED units are electrically connected to a first and a second conductive wires, one ends of the first conductive wire and the second conductive wire are respectively connected to a first end of the first one LED unit and a second end of the last one LED unit. The efficacy is that: voltages and currents of respective LED units of the entire light string are consistent and thus uniform brightness is achieved, and the number of 1-N LED units can be determined according to power of a power supply. Such parallel-type LED light string is better than a serial-type LED light string in that one abnormal LED unit does not affect other LED units, production process is simple, production cost is low and it is more suitable for decorative LED light string.
