Abstract
The utility model discloses a flash lamp lens structure comprising a flash lamp and a Fresnel lens in front of the flash lamp. One surface of the Fresnel lens facing the flash lamp is an annular tooth surface, and at least a central part of the other surface of the Fresnel lens back to the flash lamp is a concave lens. The utility model also discloses a camera device provided with the above mentioned flash lamp lens structure. The flash lamp lens structure can be used to solve the problem that the central light of the flash lamp aperture of the Fresnel lens is higher than the periphery, therefore the light emitted by the flash lamp can be more uniform, and the shot pictures can be more real.
Description
Technical field
The utility model relates to photographic equipment, the filming apparatus that particularly relates to a kind of flashing lamp lens structure and have this structure.
Background technology
Digital camera generally by the coordinating of camera and flashlamp, is realized the function of taking pictures night.The light of ordinary flash lamp projects on scene by one deck flashing lamp lens, and this layer eyeglass played the effect of protection flashlamp on the one hand, can improve on the other hand the uniformity coefficient of flashlamp light.Existing flashing lamp lens typically uses one deck Fresnel Lenses, its principle as shown in Figure 1, through the refraction of Fresnel Lenses, on scene, its uniformity coefficient has obtained obvious improvement to the light that flashlamp sends with the ray cast of similar directional light.Yet, to find in actual use, the light intensity of the aperture middle position of flashlamp will higher than the light intensity of surrounding, especially when closely taking pictures, can be felt obviously that the scene of photo center section is brighter, thereby affect the validity of photo.
The utility model content
The utility model is intended to solve flashlamp aperture central optical by force higher than the problem of surrounding, and the light that flashlamp is sent is more even, thereby makes captured photo truer.
For achieving the above object, the utility model is by the following technical solutions:
A kind of flashing lamp lens structure, Fresnel Lenses before comprising flashlamp and being arranged at described flashlamp, described Fresnel Lenses is the annular flank of tooth towards the one side of described flashlamp, and the described Fresnel Lenses another side of described flashlamp dorsad forms concavees lens at central part at least.
Can further adopt following technical schemes:
The surrounding of described central part is level crossing.
The described Fresnel Lenses another side of described flashlamp dorsad forms structures two-layer or the multilayer concavees lens.
Also comprise and be arranged on described Fresnel Lenses away from one or more layers concavees lens of a side of described flashlamp.
A kind of filming apparatus comprises described flashing lamp lens structure.
Described filming apparatus is digital camera or the mobile terminal device with camera model.
Useful technique effect of the present utility model:
On the basis of existing flashing lamp lens Fresnel Lenses, with Fresnel Lenses dorsad the another side of flashlamp namely change at least part of structure of concavees lens that is towards the one side of scene into by level crossing, after the light of flashlamp reflects through Fresnel Lenses, part light is taken turns the concavees lens refraction through one again, the effect that has diffusing light due to concavees lens, light sees through concavees lens and spreads from the mediad surrounding, thereby weakened the light intensity of aperture middle body, and the light intensity around having strengthened, more even through the light intensity of the flashlamp light after improving.Therefore, the utility model by Fresnel Lenses dorsad the one side of flashlamp form concavees lens, the photo that the camera that adopts this flashing lamp lens structure is taken is truer.Simultaneously, because the manufacture craft of concavees lens is simple, substantially can not increase the cost of manufacture of flashing lamp lens.
Description of drawings
Fig. 1 is traditional flashing lamp lens structural representation;
Fig. 2 is the structural representation of a kind of embodiment of the utility model flashing lamp lens structure.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.Should be emphasized that, following explanation is only exemplary, rather than in order to limit scope of the present utility model and application thereof.
Consult Fig. 1, in some embodiments, Fresnel Lenses 2 before the flashing lamp lens structure comprises flashlamp 1 and is arranged at described flashlamp 1, described Fresnel Lenses 2 is the annular flank of tooth 201 towards the one side of described flashlamp 1, and described Fresnel Lenses 2 another side of described flashlamp 1 dorsad forms concavees lens 202 at central part at least.
As shown in Figure 1, by Fresnel Lenses 2 is improved, flashing lamp lens after improvement becomes double-layer structure, ground floor, it is simultaneously namely the annular flank of tooth 201 of Fresnel Lenses towards flashlamp, this face is identical with existing Fresnel Lenses, is refracted as the light of similar directional light after this layer of light process structure.The second layer, be namely simultaneously that one deck central authorities are with the level crossing of concavees lens 202 towards scene, weak and do not need light to be processed for light intensity on every side, arrive scene by direct projection after level crossing, and for the central highlights (light of aperture core) that hope weakens, will light be spread to surrounding by concavees lens 202, reach and weaken central light intensity, strengthen the surrounding light intensity, make the equally distributed purpose of flashlamp light.
The diffusion effect of light is especially relevant with the focus of concavees lens, can look the optical dimensions that actual conditions suitably arrange concavees lens, especially makes its focal length satisfy the condition of the effect that can obtain to want.
If concavees lens can't reach promising result, can design two-layer even multilayer concavees lens structure.Therefore, in some embodiments, the described Fresnel Lenses another side of described flashlamp dorsad forms structures two-layer or the multilayer concavees lens, to reach desirable diffusion effect.Those skilled in the art can understand the technique that forms multilayer concavees lens structure on lens.In other embodiment, also can in the side of described Fresnel Lenses away from described flashlamp, one or more layers concavees lens be set extraly, to reach desirable diffusion effect.
In some embodiments, a kind of filming apparatus comprises described flashing lamp lens structure.
Specifically, described filming apparatus can be digital camera, can be also all kinds of mobile terminal devices with camera model, such as mobile phone, panel computer etc.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
