[0022] As Figure 1-7As shown in the figure, a spot light with adjustable lighting angle includes a radiator (1) and a lamp body (2). A steering mechanism (3) is arranged between the radiator (1) and the lamp body (2). The steering mechanism (3) includes a plastic part (8), an adapter (9), a connecting part (11) and a ball (13). The plastic part (8) is shaped with an arc-shaped protrusion in the middle of the lower end. Symmetric mounting screw holes two (801) are arranged at the top of the plastic part (8). A ball hole (802) for accommodating the ball (13) is arranged at the end face of the arc-shaped convex part in the middle of the lower end of the plastic part (8). Connecting mechanisms (901) with a "concave" - shaped opening are symmetrically arranged on both sides of the adapter (9). Mounting screw holes one (902) are arranged at both protruding parts of the "concave" - shaped connecting mechanism (901). The mounting screw holes two (801) at the top of the plastic part (8) are matched with the mounting screw holes one (902) at the protruding parts of the "concave" - shaped connecting mechanisms on both sides of the adapter (9). The plastic part (8) and the adapter (9) in the steering mechanism (3) are fixed by screws through the mounting screw holes two (801) at the top of the plastic part (8) and the mounting screw holes one (902) at the protruding parts of the "concave" - shaped connecting mechanisms on both sides of the adapter (9). A longitudinally strip - shaped limiting groove (903) is arranged on the outer wall of the adapter (9). A strip - shaped limiting protrusion (1103) with a size adapted to the limiting groove (903) is arranged at the corresponding position on the inner wall of the connecting part (11). The connecting part (11) is embedded in the limiting groove (903) on the outer wall of the adapter (9) through the limiting protrusion (1103) on the inner wall and is connected to the adapter (9) in an embedded manner. The connecting part (11) is a ring with a diameter larger than that of the adapter (9). The connecting part (11) is set as a columnar structure (1101) with a tooth surface (1102) at the top. The tooth surface (1102) has a certain arc. The ball (13) is accommodated in the ball hole (802) inside the arc - shaped protrusion on the outer wall of the plastic part (8). The ball (13) is slidably engaged with the tooth surface (1101) on the outer wall of the connecting part (11). The size of the connecting part (11) is matched with the size of the plastic part (8). The steering mechanism (3) is fixed to the bottom of the radiator (1) by screws. The lamp body (2) includes a light source (4), a lamp cup (5), a lens (6), a bracket (7), a lamp front cover (10), an outer ring (12) and an anti - glare cover (15). The light source (4), the lamp cup (5) and the lens (6) in the lamp body (2) are embedded inside the steering mechanism (3). The outer ring (12) in the lamp body (2) is placed at the bottom of the lamp cup (5). The anti - glare cover (15) is placed at the cup mouth of the lamp cup (5).The lamp body (2) is fixed to the bottom of the radiator (1) by screws. During installation, the lens 6 is sleeved on the adapter 9, then the ball 13 is nested in the ball hole 802. Next, the protruding parts of the concave "shaped connecting mechanism 901 on both sides of the adapter 9 are fixed to the plastic part 8 by screws. At this time, the upper part of the plastic part 8 is exactly flush with the upper part of the adapter 9, so that the ball 13 is engaged with the tooth surface 1102 of the connecting piece 11. Then, the adapter 9 and the connecting piece 11 are connected by screws. Then, the connecting piece 11 is rotated, and the ball 13 on the adapter 9 can sequentially contact between the two peaks and bottoms of the tooth surface 1102 and achieve smooth rotation, so as to change the irradiation angle of the spotlight according to the radian of the tooth surface 1102. At the same time, due to the groove 902 on the inner wall of the adapter 9, the corresponding protrusion 1103 on the outer wall of the connecting piece 11 is tightly combined, which plays a limiting role in the rotation of the lamp body. The spotlight structure of the present utility model is compact in design and simple in operation, with high adjustment flexibility and stability, and is applicable to a variety of lighting scenarios, especially occasions that require precise control of the lighting angle, such as stage lighting, exhibition lighting, etc.
