1. A multi-angle adjustable spot-flood light, comprising: a lamp holder (10), a light source (20), an optical assembly (30) and an angle adjustment mechanism (40);
wherein
the optical assembly (30) comprises: a first optical lens (31) and a second optical lens (32) that is spaced from and parallel to the first optical lens (31), wherein a first optical structure (106) is arranged on a light-emitting surface (104) of the first optical lens (31), and a second optical structure (107) is arranged on a light incident surface (105) of the second optical lens (32);
the angle adjustment mechanism (40) comprises: a first lens holder (41) fixedly connected to the lamp holder (10) and a second lens holder (42) rotatable relative to the first lens holder (41), wherein the first optical lens (31) is fixed on the first lens holder (41), and the second optical lens (32) is fixed on the second lens holder (42); and
an angle of the second lens holder (42) is adjusted by rotation to change a position of the second optical structure (107) on the second optical lens (32) relative to the first optical structure (106);
wherein a positioning structure (43) is further arranged between the first lens holder (41) and the second lens holder (42);
wherein the positioning structure (43) comprises a limiting elastic sheet (431) arranged on the second lens holder (42) and extending towards the first lens holder (41) and a first limiting groove (432) arranged on a peripheral wall of the first lens holder (41), wherein the limiting elastic sheet (431) is provided with a limiting bump (433) matched with the first limiting groove (432), and when the second lens holder (42) is rotated, the limiting bump (433) is embedded into the first limiting groove (432) to form limiting.
