Description

Technical Field

[0001] The utility model relates to the technical field of lighting devices for filming movies and television, in particular to a lighting device for filming movies and television. Background Art

[0002] In the process of film and television shooting, lighting devices are needed to improve the shooting effect. By using lighting devices, light and shadow can be adjusted to achieve different shooting effects. Most lighting devices refer to fill lights, which are a kind of lamps used to compensate for the lack of illumination of certain equipment. In the process of film and television shooting, the height and position of the lighting lamps are often adjusted according to the needs of the shooting.

[0003] The prior art has the following deficiencies: most of the existing lighting devices for filming can only adjust the height of the lighting lamp to provide fill light, but when it is necessary to fine-tune the angle of the lighting lamp, the operation is inconvenient and the flexibility of use is poor, resulting in a limited illumination range of the lighting device. It is difficult to meet people's needs for the use of lighting devices in filming, and the practicability is not strong. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in order to overcome the above problems, a lighting device for filming a movie is provided, which solves the above problems.

[0005] The utility model solves the technical problem by adopting the following technical solutions:

[0007] Preferably, the spring return locking rod is inserted in the hinged end block and passes through the main sleeve, and a return spring is sleeved on the outside of the spring return locking rod for pushing the spring return locking rod inward so that the front end of the spring return locking rod abuts against the outer side wall of the telescopic insertion rod to lock it; when it is necessary to release the lock, the spring return locking rod is pulled out so that its front end is out of contact with the telescopic insertion rod, and the height of the telescopic insertion rod can be conveniently moved up and down.

[0008] Preferably, in order to effectively improve the braking performance of the spring return locking rod, a rubber brake block is fixedly provided at the front end of the spring return locking rod, and the front end surface of the rubber brake block is an arc surface and matches the outer side wall of the telescopic rod.

[0009] Preferably, the hinge shaft between the articulated arms adopts a rubidium magnet shaft. In order to lighten the articulated arms, a plastic structure can be adopted. A magnetic collar which is magnetically fixed to the rubidium magnet shaft is embedded and fixed in the hinge hole at the end of the articulated arm. The magnetic attraction force between the rubidium magnet shaft and the magnetic collar can maintain the relative posture between the articulated arms. When adjustment is needed, the angle between the articulated arms can be adjusted by manually applying external force to rotate the angle. This method is simple and fast.

[0010] Preferably, in order to improve the anti-slip performance and safety of the tripod, a rubber protective plug is fixedly mounted on the lower end of each leg of the tripod.

[0011] Preferably, a rubidium magnet rotatable frame is fixed by bolts at the rear of the lighting fill light, and the rubidium magnet rotatable frame is rotatably arranged at the end of the joint arm, and a block structure for magnetically attracting the rubidium magnet rotatable frame is fixed at the end of the joint arm. When the rubidium magnet rotatable frame rotates relative to the joint arm, the rubidium magnet rotatable frame and the joint arm remain magnetically fixed, and when the illumination angle of the lighting fill light needs to be adjusted, the rubidium magnet rotatable frame can be rotated.

[0012] The advantages and positive effects of the utility model are:

[0013] 1. The bottom support area is large, which can provide a good and stable support effect, and the telescopic rod is inserted in the main sleeve to facilitate the height adjustment up and down, and the plug-in spring return locking rod can quickly release and restore the locking state of the telescopic rod, which is very convenient to use.

[0014] 2. The multi-joint arm formed by the joint arm further provides a retractable stroke, and can not only move up and down, but also make the lighting fill light displaced laterally, thereby adjusting the position within a spatial range. Moreover, since the device adopts a magnetic joint, it can support the lighting fill light while allowing adjustment to stop and move at will, which is very convenient.

[0015] 3. After the telescopic rod is completely stored and the joint arm is completely folded, the device is compact and convenient, low in cost and highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
