Description

Extendable Light Box

BACKGROUND OF THE INVENTION

1. FIELD OF THE INVENTION

100011 The present invention relates to a light box and particularly to an extendable light box, which can be collapsed as an enclosure-type light box or expanded as a wide-open type of photography system.

2. DESCRIPTION OF THE PRIOR ART

[0002] A normal light box is in enclosure type and consists of a photography platform, left lamphousing, right lamphousing, back lamphousing and top lamphousing. Positions of the related lamphousings are fixed. The enclosure-type light box gets less affection from lighting environment in photographing to create a better image quality. However, the size of a photographed object is limited by its photographing room.

100031 On the other hand, a larger photographed object can not fit the small photographing room of an enclosure-type light box. Instead, the larger photographed object is placed on an open photography platform in photographing, and surrounded by lamps or lamphousings. However, the wide-open type of photography system is seriously affected by lighting environment.

j0004J An extendable light box is disclosed, which can be collapsed as an enclosure-type light box or expanded as a wide-open type of photography system. Therefore the extendable light box can be used to shoot different sizes of photographed objects for the cost and storage space saving.

SUMMARY OF THE INVENTION

10005] According to an aspect of this invention, an extendable light box is proposed, which can be collapsed as an enclosure-type light box or expanded as a wide-open type of photography system.

[0006] According to an aspect of this invention, an extendable light box comprises a left, right and back lamphousing and a photography platform, and these lamphousings are respectively connected to the photography platform with a sliding/an extending mechanism. Using the sliding/extending mechanisms, the lamphousings can slide away from the photography platform to expand as a wide-open type of photography system. A top lamphousing is also connected to top of the back lamphousing with a rotation mechanism.

10007] According to an aspect of this invention, the photography platform and the back lamphousing can be combined as a unit. The left and right lamphousing are connected to the photography platform with sliding/extending mechanisms, and the top lamphousing is connected to the back lamphousing with a rotation mechanism. Especially, the photography platform and back lamphousing are combined in a perpendicular or round form.

[00081 According to one embodiment of this invention, the sliding/extending mechanisms of an extendable light box connecting the photography platform and left, right and back lamphousings can be implemented by slide guides or shearing-type extending units. The slide guide or shearing-type extending unit is equipped with at least one horizontal and/or vertical joint and can be horizontally rotated and/or vertically folded. The rotation mechanism connecting the back and top lamphousing is also implemented by a vertical joint. As a result, the locations and the directions of the left, right, back and top lamphousing can be adjusted to positions and orientation for lighting in photographing.

[0009] The photography platform can also be designed as a lamphousing or embedded a turntable according to one embodiment of this invention.
