Description

EXTENSIBLE LUMINOUS CABINET

The present invention relates to a light box and, in particular, to an expandable light box, which can be folded into a box-like or expanded light box in the form of a wide-opening type camera system. A normal light box is of the enclosure type and consists of a photographic platform, a left light box, a straight light box, a rear light box and a top light box. The positions of the linked light boxes are fixed. The speaker-type light box is less affected by the lighting environment in the photograph to create a better quality picture. However, the size of a photographed object is limited by its photographic chamber. Moreover, a photographed object of larger size can not adapt to the small photographic chamber of a pregnant light box. Instead, the larger photographed object is placed on a photographic platform open during photography, and surrounded by lamps or light boxes. However, the wide aperture type photography system is greatly affected by the lighting environment. According to the invention, an expandable light box is described, which can be folded into a light box of the enclosure or extended type in the form of a wide-opening type of photographic system. Therefore, the expandable light box can be used to target different dimensions of photographed objects 1 for cost savings and storage space. According to one aspect of the present invention, an expandable light box is provided, which can be folded into a box-like or extended light box in the form of a wide-opening type of photographic system. According to one aspect of the present invention, an extensible light box comprises a left light box, a right light box and a rear light box and a photographic platform, and these light boxes are respectively connected to the photographic platform with a mechanism sliding / extension.

An upper light box is also connected to the upper part of the rear light box with a rotating mechanism. According to one aspect of the present invention, the photographic platform and the rear light box can be combined in the form of a unit. The left and right light boxes are connected to the photographic platform by means of sliding / extension mechanisms, and the upper light box is connected to the rear light box by means of a rotating mechanism. In particular, the photographic platform and the rear light box are combined in a perpendicular or rounded form. According to an embodiment of the present invention, the mechanisms for sliding / extending an extensible light box connecting the photographic platform and the left, right and rear light boxes can be implemented by sliding guides or by means of shear type extension. The sliding guide or the shear type extension unit is equipped with at least one horizontal and / or vertical articulation and can be rotated horizontally and / or vertically folded. The rotary mechanism connecting the rear and top light boxes is also implemented by a vertical joint. Therefore, the locations and directions of the left, right, rear and top light boxes can be set to positions and orientations for illumination during photography. The photographic platform may also be designed as a light box or a turntable may be incorporated in the photographic platform according to an embodiment of the present invention. Other advantages of the present invention will be further apparent from the following detailed description taken in conjunction with the accompanying drawings, which are given by way of illustration and example, to make the present invention comprehensible.
