The invention relates to field of LED lamps, in particular to a novel LED street lamp. The novel LED street lamp comprises a lamp body which is provided with lamp bead cavities; LED lamp beads and lenses corresponding to the LED lamp beads are arranged in the lamp bead cavities; each lens comprises a lens substrate; each lens substrate comprises an upper plane and a lower plane; each upper plane protrudes upwards to form an upper hook face; each lower plane protrudes upwards to form a lower hook face; each upper hook face wraps the corresponding lower hook face; XYZ coordinate axes are provided; the centers of the LED lamp beads serve as the original points of the XYZ coordinate axes; and the upper hook faces and the lower hook faces are symmetrical in the direction of the X axes and not symmetrical in the direction of the Y axes. Compared with the prior art, the novel LED street lamp is reasonable in light distribution structure and good in light distribution effect.
