The utility model discloses an in a specific embodiment, as shown in fig. 13, 17 and 18, fixed ball head connecting piece 1a first adjustable ball head connecting piece 1b with second adjustable ball head connecting piece 1c is ball head screw assembly 1, ball head screw assembly 1 includes ball head screw rod 11 and ball head nut 12, ball head nut 12 card of second adjustable ball head connecting piece 1c is equipped with fixed part 5, be equipped with on the fixed part 5 and be suitable for gliding fixed part slider 6a in spout 4. Specifically, fixed part 5 can be the loop configuration, be equipped with the draw-in groove on the ball nut 12 of second adjustable ball head connecting piece 1c, fixed part 5 passes through the draw-in groove card and establishes on the ball nut 12 of second adjustable ball head connecting piece 1c, prevents that second adjustable ball head connecting piece 1c from being in relative slip on the fixed part 5, the outside of fixed part 5 is equipped with and is suitable for sliding fixed part slider 6a in spout 4.
In the process of the front and back movement of the second adjustable ball head connecting piece 1c, the second adjustable ball head connecting piece 1c can drive the fixing part 5 to move, so that the fixing part sliding block 6a can move front and back and slide in the sliding groove 4, the sliding groove 4 is compared with the sphere center of the fixed ball head connecting piece 1a, the sphere center of the first adjustable ball head connecting piece 1b and the plane slope of the sphere center of the second adjustable ball head connecting piece 1c are arranged, the front and back movement of the fixing part sliding block 6a can enable the sliding groove 4 and the lighting unit 2 to rotate with the sphere center of the fixed ball head connecting piece 1a and the connecting line of the sphere center of the first adjustable ball head connecting piece 1b as the second rotating shaft II, and therefore the dimming in the second direction is achieved. Such as: when the second direction is the left-right direction, the lighting unit 2 rotates around the second rotating shaft II, so that the dimming in the left-right direction is realized; as shown in fig. 9, when the second direction is the up-down direction, the lighting unit 2 rotates around the second rotation axis ii, thereby realizing dimming in the up-down direction.
When dimming in the first direction, the first adjustable ball head connecting piece 1b is rotated, the first adjustable ball head connecting piece 1b moves back and forth relative to the support frame or the lamp body 3, the lighting unit 2 is driven to rotate along the first direction by bypassing the center of the fixed ball head connecting piece 1a and a straight line vertical to the first direction, and dimming in the first direction is realized. At this time, the lighting unit 2 rotates relative to the support frame or the lamp body 3 along a first direction, because the sliding groove 4 is integrally arranged on the lighting unit 2, the second adjustable ball head connecting piece 1c and the fixed part sliding block 6a are fixed relative to the support frame or the lamp body 3, and the sliding groove 4 rotates relative to the fixed part sliding block 6a along the first direction, a gap exists between the sliding groove 4 and the fixed part sliding block 6a in the first direction so that the two can move relative to each other, for example, as shown in fig. 14 and 15, when the first direction is a left-right direction, gaps are arranged between the sliding groove 4 and the fixed part sliding block 6a on the left and right sides; for another example, when the first direction is the up-down direction, a gap is provided between the chute 4 and the fixed portion slider 6a on both the up-down side. Meanwhile, since the sliding groove 4 and the fixed portion slider 6a are in inclined contact fit, the sliding groove 4 moves in the first direction and also moves in the second direction relative to the fixed portion slider 6a, so that the lighting unit 2 slightly rotates in the second direction. Therefore, when dimming is performed in the first direction, dimming in the first direction is preferentially performed, and then dimming in the second direction is performed, because the lighting unit 2 slightly rotates in the second direction when dimming in the first direction is performed, and when dimming in the second direction is performed first, the projected light form of the lighting unit 2 reaches the standard position in the second direction, and after dimming in the first direction is performed, the projected light form deviates from the standard position in the second direction due to slight rotation of the lighting unit 2, and dimming accuracy in the second direction is lowered.
In another specific embodiment of the present invention, as shown in fig. 22-25, the fixed ball head connecting piece 1a, the first adjustable ball head connecting piece 1b and the second adjustable ball head connecting piece 1c are ball head screw assemblies 1, each ball head screw assembly 1 includes a ball head screw 11 and a ball head nut 12, the ball head nut slider 6b is arranged on the ball head nut 12 of the second adjustable ball head connecting piece 1c, and the ball head nut slider 6b is arranged in the sliding groove 4. The ball nut slider 6b is preferably integrally provided to the ball nut 12.
Specifically, the sliding groove 4 here may be a gap formed by two rod-shaped structures and suitable for the ball nut slider 6b to be clamped in, and one end of the ball nut slider 6b, which is far away from the ball nut 12, is provided with an opening, so that the ball nut slider 6b has better elasticity, so that the ball nut slider 6b can be better inserted into the sliding groove 4, and can be better fixed in the sliding groove 4, so that when no dimming operation is performed, the relative position of the ball nut slider 6b and the sliding groove is fixed, so as to maintain the stability of the projection light shape of the lighting unit 2.
