Description
Technical field
The utility model relates to a kind of optical texture.In addition, the utility model also relates to a kind of mobile phone with above-mentioned optical texture.
Background technology
Along with the continuous progress of technology, increasing mobile phone is integrated with camera.But when using mobile phone to take, often need flashlamp to cooperate, to obtain satisfied shooting quality.Therefore, be integrated with near the flashlamp that is arranged in the camera on the mobile phone toward contact.Usually, adopt the flashlamp with one or two led chips in mobile phone, this is because LED only occupying very little area simultaneously, can provide sufficiently high output power.Yet the shortcoming of this less LED flashlamp also is that significantly namely the flashlamp of the type only can provide the lighting point effect when taking, and this is especially more obvious when microshot.In addition, in the situation of personage's snapshot, the some flash of light can not be exported uniform illuminating effect in the zone that requires, and this is because the flashlamp of the above-mentioned type has less light output angle, and the camera in mobile phone and the close together between the model.In addition, the point of scintillation in model's eye that is caused by the above-mentioned type flashlamp has reduced the aesthetic measure of photo.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of optical texture.Form a kind of optical ring structure according to optical texture of the present utility model, this optical texture can be exported uniform flash of light, especially can glisten uniformly to subject when carrying out microshot.In addition, when taking the personage, can not produce point of scintillation in human eye, this has improved the aesthetic measure of the illumination of taking.In addition, the utility model also provides a kind of mobile phone with optical texture of the above-mentioned type.
First purpose of the present utility model realizes thus by a kind of optical texture, namely this optical texture comprises the matrix that is designed to hollow cylinder, the first end face of matrix forms the outgoing zone, the second end face of described matrix comprises incident area, the inner peripheral surface of matrix forms the first reflector space and outer peripheral face forms the second reflector space, and the second end face also comprises the 3rd reflector space, light from light source incides the matrix from incident area, and passes through the first reflector space and/or the second reflector space and/or the reflection of the 3rd reflector space afterwards from whole outgoing zone uniform in matrix.In design proposal of the present utility model, be designed to hollow cylinder as the matrix of the basic structure of optical texture.When this optical texture matches with flashlamp, penetrate after reflecting in matrix from the light of flashlamp, this has increased the light emergence angle of flashlamp light significantly.When carrying out microshot, flashlamp and subject are nearer, so flashlamp can be regarded as pointolite at this, and the light of flashlamp emission can not cover subject fully, very might form shade at subject.And adopted according to after the optical texture of the present utility model, light from flashlamp reflects in whole matrix, thereby pointolite has been become area source, increased thus the scope that the light of flashlamp covers, reduced or eliminated shade on subject.
Propose according to a preferred design proposal of the present utility model, the remainder except incident area of the second end face forms the 3rd reflector space.Owing to be mainly used in the equipment with compact flash lamp of mobile phone or other types according to optical texture of the present utility model, therefore, optical texture need to be attached on the position of flashlamp of mobile phone tightly, flashlamp is throw light on one of the second end face very little zone only, therefore be incident area corresponding to the zone design of flashlamp tightly, and other zone and dull thread are injected.If these other zones also are designed to reflector space, the light from flashlamp will be penetrated from the outgoing zone as much as possible so, and this has reduced light loss to a great extent.
Preferably, incident area is designed to groove recessed on the second end face, and the bottom surface of groove forms refraction structure.By refraction structure is set in incident area, can increases the incident angle of incident ray, thereby more be conducive to the reflection of light in reflector space.And that reflection as much as possible can make from the light of outgoing zone outgoing is more even on the whole.Advantageously, refraction structure is towards the outstanding taper shape of the openend of groove.Certainly, refraction structure also can be designed as zigzag.
Advantageously, the first reflector space, the second reflector space and the 3rd reflector space are total internal reflection region.Light from flashlamp reflects fully by these reflector spaces, and can not penetrate by these reflector spaces, and this has reduced light loss to a great extent.
Optionally, the remainder except incident area of inner peripheral surface, outer peripheral face and the second end face forms the first reflector space, the second reflector space and the 3rd reflector space by attaching reflectance coating respectively.By attaching simply the mode of reflectance coating, can in the zone of hope formation total internal reflection, form total internal reflection surface simply, the flexibility ratio that this has increased design has reduced production cost.
The first end face and the second end face are designed to the plane and parallel to each other, and this is very favorable for the homogeneity that increases emergent ray.
Propose according to a preferred design proposal of the present utility model, optical texture also comprises the maintenance structure, and this maintenance structure comprises: the maintenance framework that is clipped to photographic means; Be connected to described maintenance framework and hold the base body housing of matrix.Because optical texture is applied in the mobile phone usually, therefore when carrying out common shooting, may not need to use optical texture, so optical texture must be able to mount and dismount at mobile phone simply.Be equipped with one for this reason and keep structure, this maintenance structure can link together optical texture and mobile phone reliably.
Preferably, base body housing comprises the loading end of annular and respectively extended the first annular wall and the second annular wall on the circumferential edge of the outside of loading end and inner circumferential edge, and wherein loading end, the first annular wall and the second annular wall limit ring groove jointly.This ring groove provides spatial accommodation for the matrix of optical texture, and matrix can be fixed in the ring groove reliably.
In addition, being formed with the through hole corresponding with the position of incident area at loading end is very important.
Advantageously, keep structure also to comprise the transparency cover that seals described ring groove.Transparency cover and ring groove provide an enclosure space for matrix jointly, and this is very important for protecting more expensive matrix.
Another purpose of the present utility model realizes that by a kind of mobile phone this mobile phone comprises camera and the flashlamp of arranging adjacent to camera, wherein, also comprises the optical texture of the above-mentioned type according to mobile phone of the present utility model.
It should be understood that if there is not other dated especially the feature of different exemplary embodiment described herein can be bonded to each other.
