Description
Technical field
The present invention relates to projection field, particularly a kind of optical lens.
Background technology
In optical imaging field, in many cases, it is necessary to which light is from very large angle incidence to screen, especially ultrashort burnt throwing
Shadow instrument, is essentially all using on fish-eye lens large angle incidence to screen, in the lens of the prior art, light is from large angle incidence
When can cause the skewness of light, it is difficult to which light path is imported on screen.So as to influence the image quality of imaging, and have at the same time very big
Intensity loss.
In the prior art, optical lens is difficult to realize the leaded light of wide-angle, so that light is in very large angle incidence, light loss
Consumption is too big, and utilization rate is inadequate, and the incident angle of most light is all bigger.
In the prior art, special image light source is hardly formed high-resolution and height after the convergence and scattering of lens
The image of clarity.
The present invention provides a kind of lens arrangement of optics leaded light, can not only realize the leaded light of wide-angle, and may be used also at the same time
To retain image source clarity, and ensure that dispersion does not occur for the color for the image that image source is formed；So as to which derived light maps
High-resolution, high contrast, the image of high color reproduction degree are formed after screen or other panadaptors.
When light is from large angle incidence to lens or screen, a large amount of losses of light can be caused, and many light are reflected back,
Without occurring to import and reflecting, so that cause the utilization rate of light relatively low, and the image for causing image source to be come out at the same time
Cross-color, contrast reduce.
The content of the invention
To solve problem of the prior art, the technical solution adopted by the present invention is a kind of optical lens structure, including a base
Bottom, the substrate include upper and lower two surfaces, and the upper surface of substrate is coated with one layer of optical waveguide layer, the substrate lower surface coating
One strata photosphere, the substrate include the identical or different substrate of some refractive index；The optical waveguide layer includes some particle diameter phases
Near spheric granules；The light collecting layer includes some prism arrangements.
The prism is close to the one side of substrate to face directly or cambered surface.
The spheric granules, prism, substrate are water white transparency material, and the transmitance of light is more than 95%.
The spheric granules is corresponded with the prism, and the angle between the spheric granules and the prism is 10
~60 degree.
The refractive index of the spheric granules and the prism is between 1.0~2.0.
There is the first glue-line between the spheric granules and the substrate；There is the second glue between the substrate and the prism
Layer, the refractive index of the refractive index of first glue-line close to the spheric granules；The refractive index of second glue-line is described in
The refractive index of prism.
First glue-line, the second glue-line are transparent structure.
The spheric granules has more than 2/3rds and is exposed to outside glue-line, forms bulge-structure, the multiple raised knot
Structure is arranged together, and forms ups and downs optical waveguide layer cambered surface.
The another side of the light collecting layer is provided with combination plane mirrow of the reflectivity more than percent 90, and the plane mirror can will
Light path is turned back back along former road, and the angle of the combination plane mirrow and the optical lens is 10 to 60 degree.
The beneficial effects of the invention are as follows：The utilization rate of light is improved, the image source of reflection comes out light, can make image
Color it is true to nature, contrast improve.
