[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0036] Embodiment 1, referring to Figure 1 and Figures 4 - 8 An energy - saving stage lighting device with a multi - directionally adjustable lamp socket includes a lamp socket 1 fixedly embedded with heat dissipation fins 3;

[0037] In this embodiment, the stage light main body 2 is fixed on the lamp holder 1 through two centering and locking structures. A reciprocating heat dissipation structure is provided on the lamp holder 1, and a multi-directional adjustment structure is provided below the lamp holder 1. The multi-directional adjustment structure includes a horizontal rotation adjustment component and a pitching adjustment component;

[0038] Specifically, the horizontal rotation adjustment component includes a hollow seat 13, a rotating shaft 14 rotatably installed in the hollow seat 13, a turntable 15 coaxially welded to the outer wall of the top end of the rotating shaft 14, a first servo motor 16 fixedly installed on the side wall of the hollow seat 13, a transmission shaft 17, a driving bevel gear 18 fixedly sleeved on the transmission shaft 17, and a driven bevel gear 19 fixedly sleeved on the bottom end of the rotating shaft 14;

[0039] Further, an encoder 28 is fixedly installed on the side wall of the hollow seat 13. The first servo motor 16 can be controlled by the encoding of the encoder 28. The output shaft of the first servo motor 16 penetrates through one side of the hollow seat 13 and is coaxially and fixedly connected to one end of the transmission shaft 17 through a coupling. The driving bevel gear 18 and the driven bevel gear 19 mesh with each other and are both located inside the hollow seat 13;

[0040] Specifically, the pitching adjustment component includes a fixed shell 20 fixedly connected to the outer wall of the top of the turntable 15, a second servo motor 21 fixedly installed on the outer wall of one side of the fixed shell 20, a worm 22 fixedly sleeved on the output shaft of the second servo motor 21, a swing shaft 23 rotatably installed in the fixed shell 20, and a worm gear 24 fixedly sleeved on the middle of the swing shaft 23;

[0041] Further, the lamp holder 1 is fixedly connected to the swing shaft 23. The output shaft of the second servo motor 21 penetrates through one side of the fixed shell 20. The worm 22 and the worm gear 24 mesh with each other and are both located inside the fixed shell 20. The second servo motor 21 can be controlled by the encoding of the encoder 28;

[0042] Further, a notch 25 is opened at the top of the hollow seat 13, an annular guide groove 26 is opened in the notch 25, and a plurality of annularly distributed guide balls 27 are movably embedded on the circumferential outer wall of the turntable 15. All the guide balls 27 are in rolling fit with the annular guide groove 26. Through the rolling fit formed between the guide balls 27 and the annular guide groove 26, the friction during the rotation of the turntable 15 can be effectively reduced, so as to ensure the stability and smoothness of the rotation action of the turntable 15;

[0043] The working principle of this embodiment: First, set control commands are programmed into the first servo motor 16 and the second servo motor 21 through the encoder 28. Then, the first servo motor 16 drives the driving bevel gear 18 on the transmission shaft 17 to rotate. Subsequently, the driven bevel gear 19 meshing with the driving bevel gear 18 will drive the turntable 15 at the top end of the rotating shaft 14 to rotate, so that the stage light main body 2 rotates horizontally in all directions;

[0044] Secondly, the worm 22 is driven to rotate by the second servo motor 21, and then the worm wheel 24 meshing with the worm 22 drives the lamp holder 1 connected to the outside of the swing shaft 23 to swing back and forth, so as to facilitate the pitch angle adjustment of the stage light body 2, so that the stage light body 2 on the lamp holder 1 swings back and forth at horizontal and vertical angles, which facilitates the multi-directional adjustment of the stage light, so as to better meet the lighting construction requirements of different stage scenes, thereby achieving diversified dynamic lighting effects.

[0046] Furthermore, the driving assembly includes a mounting cover 8 fixedly mounted on the side wall of the lamp holder 1, a driving motor 9 fixedly mounted on the side wall of the mounting cover 8, a driving gear 10 fixedly mounted on the output shaft of the driving motor 9, and a transmission gear 11 fixedly mounted on one end of the reciprocating screw rod 4;

[0047] Further, the output shaft of the driving motor 9 passes through one side of the mounting cover 8, and the driving gear 10 and the transmission gear 11 mesh with each other and are both located inside the mounting cover 8;

[0048] Furthermore, a guide shaft 12 is welded inside the lamp holder 1, and the sliding plate 6 is slidably connected to the guide shaft 12. Through the guiding effect of the guide shaft 12, the stability of the linear motion of the cooling fan 7 installed on the sliding plate 6 can be ensured;

[0049] The working principle of this embodiment is as follows: during the operation of the stage light body 2, the driving motor 9 controls the driving gear 10 to rotate, and then the transmission gear 11 meshing with the driving gear 10 drives the reciprocating screw 4 to rotate, and then under the guidance of the guide shaft 12, the reciprocating slider 5 drives the cooling fan 7 installed on the top of the sliding plate 6 to reciprocate, so that the heat emitted by the stage light body 2 during the operation is evenly dissipated by the cooling fan 7 reciprocating along the outer surface of the cooling fins 3, so as to improve the heat dissipation performance of the stage light itself, make it work within the optimal temperature range, help to improve the luminous efficiency, and then reduce energy consumption, and achieve energy-saving effects.

[0050] Example 3, reference Figure 1 , Figure 7 and Figures 9 - 10, this embodiment is optimized on the basis of Embodiment 1. Specifically: the centering and locking structure includes a chute opened at the top of the lamp base 1, a bidirectional screw 29 rotatably installed in the chute, two T-shaped locking blocks 30 symmetrically screwed onto two opposite threaded ends of the bidirectional screw 29, and two positioning pins 31 symmetrically welded to the outer walls of the adjacent sides of the two T-shaped locking blocks 30. The main body 2 of the stage lamp is provided with pin holes adapted to the two positioning pins 31;

[0051] Furthermore, one end of the bidirectional screw 29 is fixedly connected with a turning cap 32, which is convenient for manually rotating the bidirectional screw 29. The outer end of the bidirectional screw 29 is provided with a locking threaded end, and a butterfly locking nut 33 is threadedly connected to the locking threaded end. Through the locking effect of the butterfly locking nut 33, it can be avoided that the two T-shaped locking blocks 30 move accidentally under the impact of external force, which is convenient for ensuring the stability of the locking of the two T-shaped locking blocks 30;

[0052] Furthermore, four insertion holes 34 are opened at the top of the lamp base 1, and insertion rods 35 are fixedly installed on the outer walls of the four corners at the bottom of the main body 2 of the stage lamp. The four insertion rods 35 are respectively inserted into the four insertion holes 34, which is convenient for ensuring the accuracy of the positioning of the main body 2 of the stage lamp;

[0053] The working principle of this embodiment: Insert the four insertion rods 35 at the bottom of the main body 2 of the stage lamp into the corresponding four pin holes to complete the preliminary positioning. Subsequently, lock it by controlling the two centering and locking structures, that is, rotate the turning cap 32 to control the rotation of the bidirectional screw 29. Subsequently, under the limitation of the chute, the two T-shaped locking blocks 30 threadedly connected to the bidirectional screw 29 will move towards the center and clamp on both sides of the main body 2 of the stage lamp. At this time, the two positioning pins 31 on the two T-shaped locking blocks 30 will be inserted into the corresponding two pin holes. Finally, tighten the butterfly locking nut 33 to complete the final locking and fixing. In this way, the effect of fixed installation can be completed without any tools, thereby improving the assembly efficiency between the stage lamp and the mounting seat.
