Embodiment Construction
[0038] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
[0039] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", The orientation or positional relationship indicated by "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying the referred device or positional relationship. Elements must have certain orientations, be constructed and operate in certain orientations, and therefore should not be construed as limitations on the invention.
[0040] Unless otherwise defined, all technical and scien...

The invention relates to the field of lighting technology, and specifically discloses a film and television light. The film and television light includes a front-end housing, a thimble, a rotating shaft, a connecting rod and an elastic limiter. The front shell is provided with a first opening facing the same direction as the light emitting surface (equivalent to the Bowens port of the video light) and a second opening facing differently from the light emitting surface. The thimble is telescopically passed through the first opening. The rotating shaft is arranged inside the front end casing and is located between the first opening and the second opening. The connecting rod is rotatably connected to the rotating shaft and arranged close to the inner wall of the front end housing. The first end of the link extends to the ejector pin and the second end of the link extends to the second opening. The elastic limiter is arranged on the rotating shaft and the elastic force acts on the connecting rod. For the video light of this solution, since the locking and unlocking structures are arranged close to the inner wall of the front shell, the rotation of the connecting rod is transformed into the linear motion of the thimble to realize the locking and unlocking of the first opening, which is beneficial to solve the problem of locking larger lighting equipment. Unlocks issues with structures interfering with radiators.
Description
technical field [0001] The invention relates to the technical field of lighting, in particular to a film and television lamp. Background technique [0002] In the film and television lighting industry, the illuminance, mixed light, soft light, light effect and other effects of the film and television lights themselves are limited, so it is often necessary to install optical accessories at the front of the film and television lights, such as focusing lenses, Fresnel lenses, soft boxes, etc. The existing video lights and optical accessories are mainly installed through the Baowen port. [0003] The existing film and television lamps have small heat dissipation requirements, and the radiator is small in size. Along the light emitting direction, the cross-sectional area of the radiator is basically equal to the cross-sectional area of the front shell. Provide force to realize the locking and unlocking of Bowens mouth. However, with the increase of film and television light...
