Abstract

A flash lamp with diffuse function comprises a light source, a reflecting bowl, a soft light plate arranged on the open end of the reflecting bowl, concentric circles arranged on the emergent plane of the soft light plate and gradually dispersing outwards in the close ladder shape, and a diffusion part arranged in the center of the incidence plane of the soft light plate and designed into a concave-convex uneven shape. The diffusion part is arranged in the center of the soft light plate, the highlight portion of the center of the light source hits the diffusion part, the reflected light is diffused in all directions, and then secondarily reflected by the reflecting bowl, the light is uniformly scattered on an illuminated object. Moreover, the area of the diffusion part is small, the diffusion effect is concentrated without light attenuation, and the light energy is not wasted.

Description

Flashlamp with diffusion function

Technical field

The utility model relates to a kind of flashlamp.

Background technology

Flashlamp is a kind of for the occasion moment illumination darker at light, strengthens the photographic part of exposure.During the flashlamp illumination, the light part that light source sends is beaten on illuminated object through softbox, and another part, through the reflection of softbox, is exported by the reflector secondary reflection.Because the reflecting surface of softbox is smooth, the reflection ray major part is back to illuminated object according to the route of once irradiating, and it is too high that exposure effect presents local luminance, the problem of illumination unevenness.In order to address this problem, existing another kind of flashlamp arranges diffuser plate outside softbox, and due to the setting of diffuser plate, the transmission rate variance of light, caused the light decay phenomenon, can't meet the demand of photoexposure amount.

Summary of the invention

The purpose of this utility model is to overcome the defect of prior art, provides a kind of energy concentrate to solve the local excessive problem of exposure effect, guarantees that exposure is sufficient and uniformly with the flashlamp of diffusion function.

For achieving the above object, the utility model adopts a kind of like this flashlamp with diffusion function, comprise light source and reflector, the openend of described reflector is provided with softbox, the exit facet of described softbox is provided with layer by layer the fine and closely woven stair-stepping donut to external diffusion, the center of the plane of incidence of described softbox also is provided with diffusion section, and described diffusion section is designed to roughness.

Especially, described diffusion section has the many terrace with edges that are regular distribution to four sides.

Compared with the prior art, the beneficial effects of the utility model are embodied in: by the center at softbox, diffusion section is set, the highlights in the center of light source divides to be beaten in diffusion section, and to all the winds scattering of reflection ray, after the secondary reflection of reflector, light equably spread on illuminated object, in addition, because the area of diffusion section is little, effect is concentrated, can not cause the light decay phenomenon, therefore can not cause the waste of luminous energy yet.

Embodiment

As shown in Fig. 1～2, a kind of flashlamp with diffusion function, comprise light source 3 and reflector 2, the openend of reflector 2 is provided with softbox 1, the exit facet of softbox 1 is provided with layer by layer the fine and closely woven stair-stepping donut 12 to external diffusion, the center of the plane of incidence of softbox 1 also is provided with diffusion section 11, and diffusion section 11 is designed to roughness.

Diffusion section 11 has the many terrace with edges 13 that are regular distribution to four sides.

Claims

1. the flashlamp with diffusion function, comprise light source and reflector, the openend of described reflector is provided with softbox, it is characterized in that: the exit facet of described softbox is provided with layer by layer the fine and closely woven stair-stepping donut to external diffusion, the center of the plane of incidence of described softbox also is provided with diffusion section, and described diffusion section is designed to roughness.
