Abstract: A lamp assembly including a front cover, a lens assembly, a light-emitting assembly, and a rear cover. The front cover and the rear cover are connected to each other to form a cavity, and the lens assembly and the light-emitting assembly are disposed in the cavity. The front cover includes a first chamber. The first chamber runs through the front cover and the lens assembly is disposed in the first chamber. The lens assembly includes a rotation trough and at least one lens. The rotation trough includes an end face, a second chamber, and an opening, and the at least one lens is disposed in the second chamber. The opening of the rotation trough is disposed towards the light-emitting assembly. A transparent plate is connected to the end face, and one end of the at least one lens is connected to the transparent plate.

Abstract: A lamp fixture, including a first bracket, a second bracket, a rotary joint, and a lamp. The second bracket includes a first subunit and a second subunit. The second bracket is rotatably connected to the first bracket. The second bracket is connected to the lamp through the rotary joint. The rotary joint is rotatably connected to the second bracket. The first bracket includes an end face opposite to the second bracket. The end face protrudes to form a first connecting block, and the end face includes a plurality of first V-shaped grooves circumferentially disposed around the first connecting block. The second bracket includes an end face opposite to the first bracket. The end face includes a first bulge corresponding to the plurality of first V-shaped grooves. The end face includes a first through hole to receive the first connecting block.
