Abstract

The utility model relates to a soft light box for photographing, which comprises a shield that has an inner light reflecting surface. The light source is arranged at the center position of the shield; an inner and outer soft light cloth are arranged inside the shield; the flat surface of the soft light cloth is in a vertical opposition with the light source; a light reflecting cloth is connected to the center part of the surface dead against the light source of the inner soft light cloth. The reflecting cloth on the inner soft light cloth is dead against the direct lighting position of the light source, therefore can avoid partial overlighting of the light source, and the light reflected back goes through defused reflection by the inner surface of the shield before going through the inner soft light cloth, making the light reaching the outer soft light cloth better distributed with the illumination of the edge and the center is basically the same, improving the photography effect.

Description

The photography soft box

Technical field: the utility model relates to a kind of photographic eyepiece light annex, particularly soft box.

Background technology: in photography, need the pointolite of photography luminaire be converted to uniform area light source with soft box.General soft box utilization is over against the inside and outside two layers of sheen cloth and the interior reflective case scattering homogenizing light of light source, but because light source is a direct projection light, the brightness of the center section that soft box is broken forth also can be stronger than the edge, do not meet the Professional Photography requirement, light is even inadequately, forms by photography thing hot spot or reflection easily.

Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of illumination plane light photography soft box uniformly.

The utility model comprises the case of inner surface for reflecting, light source arrangement is at the case bottom centre position, be provided with the sheen cloth of inside and outside two layers of parallel interval in the case, sheen cloth plane and light source are vertically opposite, connect over against the lip-deep centre of light source at interior sheen cloth to be coated with reflective cloth.

Reflective cloth on internal layer sheen cloth is over against light source direct projection position, can prevent that the pointolite part is bright excessively, and the light of reflected back passes through interior sheen cloth again after the diffuse reflection of case inside surface, can make the light that arrives outer sheen cloth more even, the edge is the same substantially with central ray brightness, improve the effect of photography, and can reduce the light losing that cuts off direct light.

Further specify the utility model below in conjunction with drawings and Examples.

Description of drawings: Fig. 1 is the main structure synoptic diagram of embodiment;

Fig. 2 is the front view of interior sheen cloth;

Fig. 3 is the A-A cut-open view of Fig. 2.

Embodiment: as shown in the figure, the inner surface for reflecting of case 1, light source 2 is arranged in case 1 bottom centre position, is provided with the interior sheen cloth 3 and the outer sheen cloth 4 of two layers of parallel interval in the case 1, and sheen cloth plane and light source 2 are vertically opposite.Connect over against the lip-deep centre of light source 2 at interior sheen cloth 3 and to be coated with reflective cloth 5.According to the distance of interior sheen cloth 3 and light source 2 and the intensity of light source 2 etc., the 3-15% on sheen cloth 3 surfaces in the area coverage of reflective cloth 5 accounts for, also can connect certainly needs to adjust.In order to make the sheen effect more even, reflective cloth 5 is generally with circular.If interior sheen cloth 2 itself is shaped as non-centrosymmetry shapes such as rectangle, can also cover one deck sheen layer of cloth 6 again on interior sheen cloth 3 surfaces of the nearer two side portions of distance center, direct projection light in center is by reflective cloth 5 reflections like this, apart from nearer two sides, center than the high light line then by the softening of double-deck sheen cloth, can make the distribution of light of throwing on the outer sheen cloth 4 more even.

Claims

1, a kind of photography soft box, the case that comprises inner surface for reflecting, light source arrangement is at the case bottom centre position, be provided with the sheen cloth of inside and outside two layers of parallel interval in the case, sheen cloth plane and light source are vertically opposite, it is characterized by: connect over against the lip-deep centre of light source (2) at interior sheen cloth (3) and be coated with reflective cloth (5).
