[0023] Reference Figures 1-4 A lighting device for film and television shooting includes a support plate 1 and a lighting lamp 23. Multiple support blocks 2 are snapped onto the outer circumference of the support plate 1, thereby increasing the contact area between the bottom of the lighting device and the ground and improving the stability of the lighting device. A rotating disk 4 is rotatably embedded in the support plate 1 and protrudes from the top of the support plate 1. Turning the rotating disk 4 causes the lighting lamp 23 to rotate, thereby adjusting the direction of the lighting. The top of the rotating disk 4 is provided with multiple second rectangular grooves 5. A locking block 7 is slidably connected in the second rectangular groove 5. A first spring 6 is welded to the bottom of the locking block 7. The bottom end of the first spring 6 is fixedly connected to the bottom inner wall of the second rectangular groove 5. The top of the support plate 1 is provided with multiple first rectangular grooves 3. The locking block 7 is snapped into the first rectangular groove 3. Under the action of the first spring 6, the locking block 7 is snapped into the first rectangular groove 3, thereby fixing the rotating disk 4 and fixing the direction of the lighting.

[0024] A guide cylinder 8 is welded to the top of the rotating disk 4. A slide rod 9 is slidably inserted into the top of the guide cylinder 8. A support frame 12 is fixed to the top of the slide rod 9 by bolts. Pulling the slide rod 9 to move inside the guide cylinder 8 will move the support frame 12, which in turn will move the lighting lamp 23, thus adjusting the lighting height. Multiple positioning holes 10 are provided on one side of the slide rod 9. A positioning pin 11 is threaded into one side of the guide cylinder 8. The positioning pin 11 is inserted into the positioning hole 10. Inserting the positioning pin 11 into the positioning hole 10 will fix the slide rod 9, thereby fixing the lighting height.

[0025] A mounting box 13 is welded to the other end of the support frame 12. A connecting cylinder 14 is fixedly inserted between the two ends of the mounting box 13. A rotating rod 15 is rotatably inserted into the connecting cylinder 14. The outer circumference of the rotating rod 15 is provided with multiple slots 16. A connecting frame 17 is fixed between the two ends of the rotating rod 15 by bolts. The lighting lamp 23 is fixed to one side of the connecting frame 17 by bolts. Twisting the rotating rod 15 causes the connecting frame 17 to rotate, thereby causing the lighting lamp 23 to rotate and thus adjusting the lighting angle of the lighting lamp 23. A mounting frame 18 is welded to the top of the mounting box 13. The top of the mounting frame 18 is provided with two sliding grooves 19. An L-shaped support rod 20 is slidably connected in the sliding grooves 19. A lever is welded to the top of the L-shaped support rod 20. 22.

[0026] The working principle of this embodiment is as follows: When adjusting the lighting direction, the rotating disk 4 is turned to rotate the lighting lamp 23, thereby adjusting the lighting direction. After adjustment, the first spring 6 causes the locking block 7 to engage with the first rectangular groove 3, thereby fixing the rotating disk 4 and thus fixing the lighting direction. When adjusting the height, the sliding rod 9 is pulled to move inside the guide cylinder 8, thereby moving the support frame 12 and then the lighting lamp 23, thus adjusting the lighting height. Then, the positioning pin 11 is inserted into the positioning hole 10 to fix the sliding rod 9, thereby fixing the lighting height.

[0027] When adjusting the angle, squeeze the lever 22 inward to bring the two L-shaped support rods 20 together in the middle. Then, turn the rotating rod 15 to rotate the connecting frame 17, thereby rotating the lamp 23 and adjusting the lighting angle of the lamp 23. Then, release the lever 22, and under the action of the second spring 21, the two L-shaped support rods 20 move to both sides, so that the bottom end of the L-shaped support rod 20 engages with the slot 16, thereby fixing the rotating rod 15 and fixing the lighting angle. When not in use, cover one side of the lamp 23 with the protective plate 24 to protect the lamp 23.
