Description

Technical Field

[0001] The utility model relates to the technical field related to fill light components, in particular to a fill light steering adjustment device. Background Art

[0002] A fill light is a lamp used to compensate for the light of certain devices or plants due to lack of illumination. It is widely used in various photography and video scenes, especially suitable for close-up shooting of small objects, portraits, food, etc. The working principle of a fill light is mainly to generate light through a bulb, and then evenly project the light onto the target object through a specific reflection method. A fill light usually consists of one or more bulbs and a corresponding reflector. As a light source, the bulb can generate light of sufficient brightness. The reflector diffuses and gathers the light to ensure that the light can evenly illuminate the target. The reflector of the fill light usually adopts the principle of mirror reflection or diffuse reflection. There are various types of fill lights, which can be classified according to the different light sources used. For example, fluorescent lamps, as a common light source, are widely used in fill lights. In addition, there are LED fill lights, which are suitable for various photography and video scenes, such as film and television shooting, beauty live broadcasting, selfie photography, etc. LED fill light sticks are suitable for portrait photography and small scene shooting. With the continuous advancement of photography technology, the importance of light in photography has gradually been recognized by people. Fill lights, as a device that can adjust and improve the light in the shooting environment, have been widely used. However, the light provided by the fill light alone is not enough to meet all shooting needs. During shooting, it is often necessary to adjust the angle and position of the fill light according to different shooting scenes and objects to obtain the best lighting effect. This requires a convenient and flexible fill light steering adjustment device. Utility Model Content

A hand-held turntable is fixedly mounted on one end of the rotating shaft 8.

[0024] By rotating the shaft 8, the gear 9 is driven to rotate, and the gear 9 drives the rack 6 to move up and down, and the rack 6 moves synchronously with the movable frame 4. The lamp body 5 on the movable frame 4 can move in the vertical direction, so as to adjust the height of the lamp body 5. Then, the limit pin 12 is inserted into the jack 11 and inserted into the housing 7, so that the gear 9 can be fixed, thereby fixing the incoming wire of the movable frame 4, and keeping the height of the lamp body 5 in a fixed state. By providing a rotatable mounting seat 2, the vertical tube 3 is installed on the mounting seat 2, and the lamp body 5 can be driven to rotate by rotating the vertical tube 3, so as to adjust the lighting direction of the lamp body 5.

[0025] The mounting seat 2 is provided with a plurality of pressure blocks 13 distributed in a circular array, and connecting rods 14 are hinged on both sides of the pressure blocks 13, and the ends of the connecting rods 14 are installed on the support frame 1. The pressure blocks 13 are fixedly connected with elastic members 15, and one end of the elastic member 15 is fixedly connected to the support frame 1. The pressure blocks 13 are in contact with the outer side of the mounting seat 2, and the contact surface is set to be arc-shaped. An adjustable mobile phone holder 16 is installed on the movable frame 4. By setting the elastic force of the elastic member 15 to drive the pressure blocks 13 to press on the outer side of the mounting seat 2, the mounting seat 2 can be made difficult to rotate when rotating. When the vertical cylinder 3 is rotated to drive the lamp body 5 to rotate, the angle of the lamp body 5 is not easy to change and is in a relatively stable state.
