[0028] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0030] See also Figure 1-Figure 7 As shown, the utility model is a light adjustment device, including a mounting base 1, a first support rod 2 is fixedly installed on the top of the mounting base 1, a second support rod 3 is slidably installed in the inner cavity of the first support rod 2, a lifting component 4 is fixedly installed on the top of the second support rod 3, one end of the lifting component 4 is fixedly installed on the first support rod 2, an adjustment component 5 is fixedly installed on the top of the second support rod 3, a lamp body 6 is fixedly installed on one end of the adjustment component 5, a plurality of dimming components 7 are rotatably installed on one end of the adjustment component 5 close to the lamp body 6, and the plurality of dimming components 7 are equidistant between each other.

[0031] When in use, first place the mounting base 1 where light is needed. When the height of the lamp body 6 needs to be adjusted, the lifting assembly 4 in the inner cavity of the first support rod 2 will be driven to rotate first, and then the lifting assembly 4 will drive the second support rod 3 fixedly installed in the middle to move in the inner cavity of the first support rod 2, and then the length of the second support rod 3 in the inner cavity of the first support rod 2 will change. When the second support rod 3 is raised, the length of the first support rod 2 will become shorter, and then the second support rod 3 will drive the adjustment assembly 5 fixedly installed on the top to move. At the same time, the adjustment assembly 5 will drive the lamp body 6 fixedly installed on one side to move, so as to adjust the height of the lamp body 6. When the light of the lighting lamp needs to be adjusted, the adjustment assembly 5 is driven to move toward one end away from or close to the lamp body 6, and then the adjustment assembly 5 will drive several dimming assemblies 7 that are rotatably installed to move, so that the two adjacent dimming assemblies 7 are moved away from each other, and the distance between them becomes larger or smaller, so that the light emitted by the lamp body 6 can be better gathered together at the film and television shooting scene, or its irradiation range is increased.

[0032] Thus, by driving the adjusting component 5 to move toward one end away from or close to the lamp body 6, the two adjacent dimming components 7 are moved away from each other and the distance between them is increased or decreased. The light emitted by the lamp body 6 can be better gathered together at the film and television shooting scene, or its irradiation range can be increased, and the light irradiated by the lamp body 6 can be better regulated, thereby increasing the utilization rate of the light emitted by the lighting lamp and making the lighting of the lighting lamp clearer.

[0033] Thus, by driving the lifting assembly 4 in the inner cavity of the first support rod 2 to rotate, the length of the second support rod 3 on the first support rod 2 will become shorter when it is raised. Then the second support rod 3 will drive the top adjustment assembly 5 and the lamp body 6 to move, so that the height of the lamp body 6 can be increased or decreased, thereby facilitating the needs of film and television shooting, making the film and television shooting more convenient, and solving the problem of the inconvenience of lifting and lowering of general film and television shooting lighting lamps.

First, the gravity on the first support rod 2 will be given to the fixed base 101 below, and then the base 101 will disperse the gravity to the several support legs 102 rotatably installed on the circumferential surface. Then the several support legs 102 will transmit the gravity to the connecting rod 103 fixedly installed thereon. Since the ends of the several connecting rods 103 close to each other are fixedly installed on the round rod 104, the bearing capacity of the device is increased by remembering the association between the fixed installations, so that the device can be more secure.

[0036] In one embodiment, for the above-mentioned lifting component 4, the lifting component 4 includes a driving motor 401, and the driving motor 401 is fixedly installed on the outer wall of the first support rod 2.

[0038] When the height of the lamp body 6 needs to be adjusted, the first synchronous wheel 402 fixedly installed at the output end of the driving motor 401 will be driven to rotate, and then the first synchronous wheel 402 will drive the rotatably installed synchronous belt 403 to rotate. Since the second synchronous wheel 404 is rotatably installed on the first support rod 2, the synchronous belt 403 will rotate under the support of the second synchronous wheel 404 rotatably installed at the other end. Since the bottom of the second support rod 3 is fixedly installed in the middle of the synchronous belt 403, the synchronous belt 403 will drive the second support rod 3 to move, and then the length of the second support rod 3 in the inner cavity of the first support rod 2 will change. When raised, the length of the second support rod 3 in the first support rod 2 will become shorter, and then the second support rod 3 will drive the adjusting component 5 fixedly installed on the top to move, thereby changing the height of the lamp body 6, so that the height of the lamp body 6 can be increased or decreased, thereby facilitating the needs of film and television shooting, making the film and television shooting more convenient, and solving the problem of inconvenient lifting and lowering of general film and television shooting lighting.

[0041] The adjusting rod 701 is arranged in an L shape, and the adjusting disk 503 is located in the inner cavity of the shell 501 .

[0042] When it is necessary to adjust the light of the lighting lamp, the output end of the driving telescopic rod 502 drives the fixedly installed adjusting disk 503 to move toward one end away from or close to the lamp body 6, and then the adjusting disk 503 will drive the plurality of adjusting rods 701 rotatably installed on the rotatable circular surface to rotate, so that the plurality of adjusting rods 701 are moved away from each other, and then the plurality of adjusting rods 701 will drive the fixedly installed adjusting cloths 702 to rotate, and make the distance between the adjusting cloths 702 larger or smaller, so that the light emitted by the lamp body 6 can be better gathered together at the film and television shooting scene, or its irradiation range is increased, thereby increasing the utilization rate of the light emitted by the lighting lamp and making the lighting of the lighting lamp clearer.
