Description

Technical Field

[0001] The utility model relates to the technical field of lighting equipment, in particular to a lighting equipment for scene light perception compensation. Background Art

[0002] Among lighting equipment, fill light boards are mostly used for light compensation. Since the size of fill light boards is generally fixed, although the brightness and color can be adjusted, the light source cannot be cut to size. When scene light compensation is used, fill light boards of different sizes are required, which requires switching to fill light boards of different sizes. However, there are a large number of fill light boards in use and they are arranged around the scene. If it is necessary to switch to fill light boards of different sizes, the shooting efficiency will be reduced. Even if fill light boards of different sizes can be switched, it is only a change in size. The fill light profile is still limited and cannot meet the adaptive light requirements. Therefore, we propose a lighting device for scene light compensation. Utility Model Content

[0003] The purpose of the present utility model is to solve the shortcomings existing in the prior art. A large number of fill light boards are used and are arranged around the scene. If it is necessary to switch fill light boards of different sizes, the shooting efficiency will be reduced. Even if fill light boards of different sizes can be switched, it is only a change in size. The fill light profile is still limited and cannot meet the adaptive light perception requirements.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A lighting device for scene light perception compensation includes a fill light board, wherein first light adjustment structures are symmetrically provided on both sides of the fill light board, and a second light adjustment structure is provided on the bottom of the fill light board;

[0006] The first illumination adjustment structure includes a transverse adjustment rod, a first sliding support assembly and a first light shielding plate, wherein the first sliding support assembly is slidably connected to the transverse adjustment rod and is provided with the first light shielding plate;

[0007] The second illumination adjustment structure includes a vertical adjustment rod, a second sliding support assembly and a second shading plate. The second sliding support assembly is slidably connected to the vertical adjustment rod and is equipped with the second shading plate.

[0008] Furthermore, there are two lateral adjustment rods, which are installed on the sides of the fill light board near the upper and lower ends, and a first limiting plate is installed between the ends of the lateral adjustment rods away from the fill light board.

[0009] Furthermore, the first sliding support assembly has two groups, including a slider a and a connecting rod a. The slider a is provided with two sliders respectively sleeved on the periphery of the two lateral adjustment rods and connected by the connecting rod a. The two groups of the first sliding support assembly are connected by the connecting rod b.

[0010] Furthermore, there are two vertical adjustment rods, which are installed at the bottom of the fill light board near both sides, and a second limiting plate is installed between the ends of the vertical adjustment rods away from the fill light board.

[0011] Furthermore, the second sliding support assembly includes a slider b and a connecting rod c. The slider b is provided with two sliders respectively sleeved on the periphery of the two vertical adjustment rods and connected by the connecting rod c.

[0012] Furthermore, a threaded adjustment hole is provided on the outside of the slider b and extends through the vertical adjustment rod. A locking knob is threadedly connected in the threaded adjustment hole. A contact surface is provided on the vertical adjustment rod along the length direction corresponding to the threaded adjustment hole.

[0013] Furthermore, the slider a and the slider b are provided with a mounting seat on the same side as the light source of the fill light board, and a protrusion is provided on the top of the mounting seat, and the protrusion of the slider b is located in front of the protrusion of the slider a.

[0014] Furthermore, buckle seats are installed at the corresponding protrusions on the back sides of the first light shielding plate and the second light shielding plate, and the first light shielding plate and the second light shielding plate are installed by docking the buckle seats with the protrusions.

[0015] Furthermore, the first shading plate and the second shading plate are provided with a temperature insulation layer on the light source side of the fill light panel.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. Through the design of the first and second light adjustment structures, the size and shape of the fill light panel's light source can be flexibly adjusted. Whether horizontally or vertically, precise adjustments can be made through the sliding support assembly and the shading plate to meet the light compensation requirements in different scenes.

[0018] Among them, since the shading plate is designed to be disassembled, it can be replaced with shading plates of different sizes and shapes, such as arc-shaped or bevel-shaped, so as to meet the needs of adjusting the size and shape of the light source of the fill light board.

[0019] 2. The sliding adjustment and shading plate design eliminates the need to frequently replace fill light panels of different sizes, significantly improving shooting efficiency. Photographers or operators only need to simply adjust the position of the shading plate to adjust the light sensitivity compensation, which is extremely convenient and highly applicable.

[0020] To sum up, since there is no need to prepare fill light panels of various sizes, the purchase cost of the equipment is reduced, while the shooting efficiency is improved, and the labor cost and time cost are indirectly reduced. The scene light compensation lighting equipment of the present invention solves the shortcomings of the existing technology through innovative design, and has the advantages of adaptively adjusting light requirements, improving shooting efficiency and reducing costs.
