Description

Symmetrical light box with uniform illumination

technical field

The utility model relates to a light box, in particular to a symmetrical light source light box with high light uniformity and uniform illumination. .

Background technique

With the vigorous development of technological networks, e-commerce and online stores are becoming more and more popular. Consumers can easily shop at home through computers and information networks regardless of weather and time. , all racking their brains to perfectly present all products in front of consumers in their product catalogues. Therefore, in order to provide consumers with the most beautiful and correct product photos, when using a digital camera or a general camera for physical shooting, there must be sufficient and uniform light source in order to shoot a more beautiful and correct color image, so when shooting When shooting, a symmetrical light box with uniform illumination is generally used to provide the light source needed for shooting.

A known symmetrical light source light box 10 with uniform illumination, as shown in Figure 1, forms an opening 14 on one side of a box body 12, so that the real object to be photographed is placed in the box body 12 through the opening 14, and has A plurality of lamp tubes 16 arranged in parallel at intervals are arranged on the inner top surface of the box body 12, and a plane diffuser plate 18 is arranged below the lamp tubes 16, so as to produce a uniform light source and irradiate the surface of the object to be photographed; In the symmetrical light source lamp box 10 with uniform illumination, since the lamp tube 16 is only arranged on the inner top surface of the box body 12, the light source generated by the lamp tube 16 can only produce relatively uniform brightness on a single plane, rather than a three-dimensional uniform light source, so It is only suitable for color matching of flat objects, and the symmetrical light source light box 10 with uniform illumination can easily make the brightness of the area directly under the lamp tube 16 brighter than other areas, but has the disadvantage of high color matching distortion rate.

Another known symmetrical light source light box 10 for photographing jewelry with uniform illumination is shown in FIG. A light tube 16 is provided on each of the three inner sides of the box body 12 without the opening 14, so as to provide jewelry light sources from three directions, and a slot is arranged on the top surface of the box body 12 to set up a camera 20; but this kind of illumination is uniform The design of the symmetrical light source light box 10 can only provide sufficient light source when photographing jewelry because the light source is not symmetrical, but cannot provide uniform light source in all directions.

Moreover, because the above two symmetrical light source light boxes 10 with uniform illumination are all formed with an opening 14, when shooting, the box body 12 cannot maintain a closed state completely isolated from the external light source, so the light source inside the box body 12 is easily affected by the external light source. Influenced by it, resulting in the lack of uneven brightness and color distortion.

Contents of the invention

Aiming at the shortcomings of the prior art, the utility model provides a symmetrical light source light box with uniform illumination.

The technical scheme adopted by the utility model is: a symmetrical light source light box with uniform illumination, including: a box body, a vertical lamp tube and a diffuser plate; One side of the cabinet is provided with a movable door; a plurality of vertical light tubes are arranged symmetrically on the inner side of the box; a plurality of diffusion plates are respectively arranged on the periphery of the vertical light tubes, and the outer surface of each diffusion plate is Evenly covered with many particles.

The diffuser is a semicircular cover.

The diffuser is a flat plate.

The diffuser plate is integrally formed by two straight plates and an arc plate connecting the two straight plates.

The two straight plates are arranged in an obtuse angle relationship.

The inner surface of the box is matte.

The utility model provides a uniform light source in each direction of the three-dimensional object to be photographed, so that the three-dimensional object can show more correct colors in all directions; the utility model proposes a closed symmetrical light source light box with uniform illumination to isolate the external light source interference, so that the interior of the box has a better and fixed light source environment, which is convenient for shooting.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail. As shown in Figures 3 and 4, a symmetrical light source light box 30 with uniform illumination includes a rectangular box body 32, and an opening 34 is arranged in the center of its top surface for erecting a camera, and the camera lens extends into the inside of the box body 32 In order to facilitate physical photography, a dodge door 36 is arranged on one side of the casing 32, so that the object to be photographed is placed in the casing 32 through the opening of the dodge door 36, and the inside four corners of the casing 32 are respectively arranged There is a lamp frame 38, and a vertical lamp tube 40 is installed on each lamp frame 38, and four diffuser plates 42 are respectively covered on the periphery of each vertical lamp tube 40, and each diffuser plate 42 is connected by two straight plates 44 and a The curved plates 46 of the two straight plates 44 are integrally formed, and the outer surface of each diffuser plate 42 is evenly covered with a plurality of particles 48 .

Wherein, the inner surface of the above-mentioned box body 32 is also treated with a matte surface or coated with gray paint, so that the inner surface of the box body 32 has the function of uniform astigmatism, and the two straight plates 44 in the astigmatism plate 42 are arranged with an obtuse angle relationship, so that by The light beams emitted by each vertical lamp tube 40 are evenly emitted through the diffuser plate 42 and then diffused by the uniform particles 48 on the surface of the diffuser plate 42 to produce uniform brightness in all directions in the box body 32 .

In the utility model, when the three-dimensional object to be photographed is placed inside the box body 32, as shown in Figure 5, with the closing of the movable door 36 and the erection of the camera 50, a closed space will be formed inside the box body 32. , without being disturbed by external light sources, thus having a better and fixed light source environment, and because the vertical lamp tube 40 itself produces a uniform light source in each direction in the symmetrical light source light box 30 with uniform illumination, when shooting a three-dimensional object, Each point of the three-dimensional object can be displayed in a more accurate color, so that after the image with a more accurate color is transmitted through the network, the remote receiver can get the information of the correct color of the object.

In the utility model, in addition to the structure of the symmetrical light source light box 10 with uniform illumination, as shown in Figure 6 and Figure 7, a triangular light frame 38 is respectively arranged in the center of the inner side surface around the box body 32, and A symmetrical vertical lamp tube 40 is respectively arranged on the two sides of each triangular lamp holder 38, and four flat diffuser plates 42 are respectively arranged in front of each triangular lamp holder 38, and the four diffuser plates 42 enclose a rectangle Space, so that when shooting, the real object to be photographed is placed in a rectangular space, and the corresponding outer surface of the four-diffusion plate 42 is covered with a plurality of particles 48, so that the light beam produced by the vertical lamp 40 is evenly scattered in the rectangular space. in space.

In addition, as shown in Figure 8, the box body 32 can be a cylindrical structure, and four lamp holders 38 equipped with vertical lamp tubes 40 are arranged symmetrically inside the box body 32, and each vertical lamp tube The periphery of 40 is covered with a diffuser plate 42, which is a semicircular cover body, and its outer surface is evenly covered with a plurality of particles 48, so that the light beam generated by the vertical lamp tube 40 can be diffused by the diffuser plate 42. Uniform brightness in all directions is generated inside the cabinet 32 .
