The embodiment of the utility model provides an LED point light source which comprises a lamp holder, a PCB assembled in the lamp holder, LED chips assembled on the PCB and lampshades used for covering the LED chips, the LED chips are assembled on the two opposite side faces of the PCB, the outer side of the LED chip on each side is provided with one lampshade, and the LED chips are assembled on the two opposite side faces of the PCB. The lampshade is in a dome shape and is fixedly connected with the corresponding sides of the lamp holder. According to the embodiment of the utility model, the LED chips are assembled on the two opposite side surfaces of the PCB, and the lampshade is arranged on the outer side of the LED chip on each side, so that double-sided large-angle light emission is realized; the lampshade is arranged to be in a dome shape, when the LED point light source is used for outdoor illumination or decoration, the dome-shaped lampshade can effectively reduce resistance to wind through the stream
