Technical background: in order to achieve the concentrating effect of light source, the usual practice is to use a paraboloid of concentrated reflection cup, this reflection cup is difficult to use in light emitting Angle smaller light source; In the existing technology of the light source by convex lens condenser, the condenser lens is not a real full condenser lens, only a partial condenser lens reflector, reflective surface is usually made up of parabolic or hyperbolic rotation, because of the light source through the air when they enter the lens refraction to the reflecting surface first, every Angle all have deviation, hence cannot really concentrated, another part of the light is as light scattering. Technology factors: the purpose of the utility model is to solve some problems in the existing technology, and put forward a kind of high optical lens. In order to achieve the above purpose, the utility model adopts the following technical scheme: a high optical lenses, including the lens body, described the lens body frustum of a cone shaped structure, as described in the bottom of the lens body inward concave form for cavity, described for the bottom of the chamber for the first into the smooth, described for the sidewalls of the cavity for the total reflection surface, described for the top of the cavity has a cavity, as described in the bottom of the cavity for the first out of the smooth, described the sidewalls of the cavity from the inside-out, in turn, has multiple circular saw, circular saw and described several described the first out of the cavity of smooth formation, each circular saw are described including the second into the smooth surface and a second out smooth, mentioned in the circular saw toothed slot, formed between each described in the shape of the tooth is exactly the same size. Optimization, described the first into the smooth surface of radius of curvature is greater than and described the first smooth radius of curvature. Optimization, described for the side of the cavity for on wide below narrow frustum of a cone surface, and for the diameter of the cavity bottom is greater than the diameter of the bottom openings. Optimization of total reflection surface is described by at least more than two pieces of paraboloid mentioned first formed into smooth the central axis of rotation. Mentioned in optimization of multiple circular saw by radius outside introversion, in turn, increases, and all circular saw described first out smooth distribution of concentric circles centered circle. Optimization, described for the bottom of the cavity and referred to the bottom of the cavity form convex lens. Compared with the existing technology, the utility model provides a high optical lens, has the following beneficial effects: 1, the high optical lenses, by setting the inward concave for cavity and cavity on the bottom of the form convex lens, and cooperate with the total reflection surface realize high-efficiency condenser. 2, the high optical lenses, through the cavity wall is equipped with multiple circular saw, each circular saw are including the second into the smooth and the second a smooth surface, which can effectively prevent the light scattering. Not involved in the device's parts are the same as the existing technology or the existing technology can be used to implement, the utility model has simple structure, convenient operation, through the hold light for cavity to make light completely absorbed by the projection lens, then through the total reflection surface will focus on the smooth surface, light and through the lens of the light gathered further, finally further reflects make contracts with annular sawtooth effect to further improve, reduced the incidence of false light. Figure 1 illustrated instructions for the utility model is put forward a kind of high optical lens structure schematic diagram; Figure 2 for the utility model proposed by the top view of a high optical lens. Graph: the lens body, 2 for 1 cavity first into the smooth, 3, 4 total reflection surface, 5, 6, the first cavity smooth, 7 circular saw, 8 second into smooth, 9 alveolar, 10 second smooth, 11, convex lens. Concrete implementation way of the following will be combined with the appended drawings of the utility model implementation, this utility model implementation case clearly and completely describe the technical scheme of obviously, described the implementation of the case is just a part of the utility model implementation example, rather than the implementation of all cases. In description of the utility model, the need to understand is that the term 'up', 'down', 'before' and 'after', 'left', 'right', 'top', 'bottom', 'inside' and 'outside' indicates a location or position relations based on the location or position shown in the appended drawings, only is to facilitate the description of this utility model and simplified description, rather than instructions referred to in or implied devices or components must have a specific location, in a specific orientation structure and operation, therefore cannot be interpreted as limiting the utility model. Refer to figure 1 2, a kind of high optical lenses, including the lens body 1, lens 1 frustum of a cone shaped structure of ontology, the bottom of the lens body 1 inward concave form for cavity 2, for the bottom of the cavity 2 for the first into the smooth 3, for the sidewalls of the cavity 2 of total reflection surface 4, for the top of the cavity 2 has 5 cavity, and the bottom of the cavity 5 for the first smooth 6, the sidewalls of the cavity 5 by outside introversion, in turn, is equipped with multiple circular saw 7, 7 with multiple circular saw for the first out smooth forming cavity 5, 6 each circular saw 7 include a second into the smooth the second smooth 10, 8 and 7 have tooth groove formed between each circular saw 9, 9 each tooth shape is exactly the same size. First into the smooth and radius of curvature is greater than the first 3 smooth 6 curvature radius, for the side of the cavity 2 for on wide below narrow frustum of a cone surface, and for the diameter of the cavity 2 underside is greater than the diameter of the bottom open, total reflection surface 4 consists of at least two parabolic shaft rotation around the center of the first into the smooth 3, 7 by multiple circular saw radius outside introversion, in turn, increases, and all of the circular saw seven smooth surface in the first six concentric circles centered circle distribution, for the bottom of the cavity 2 and referred to the bottom of the cavity 5 convex lens 11. The utility model, through to accommodate the light source for 2 make the light source is completely absorbed by the lens body cavity, then through the total reflection surface 4 focuses light on the first issued a smooth on 6, and through the lens of the light gathered further, at last, by further circular saw seven refraction that further improve the focusing effect, reduced the incidence of false light. In this article, such as the first and second class relations terminology used to only one entity or with another entity or operation, and does not necessarily require or suggest that these entities or any operation between the actual relationship or order. Also, the term 'including' and 'include' or any of its other variants is intended to cover a non-exclusive contain, which includes a series of elements of the process, method, item or equipment not only includes those elements, but also no clear list of other elements, or also includes objects for the process, method, or device inherent elements. 'Finite elements, does not rule out in the process, methods, including elements described items or equipment still exist in the other elements of the same. Despite shows and describes the implementation of the utility model, for the purpose of this general technical personnel in the field of, can understand the principle and spirit is not out of the utility model can for those patients with a variety of changes, modification, replacement and variant, the scope of the utility model by the attached claims and their equivalents. Described above, only for the specific implementation of the utility model is better, but the breadth of the utility model is not limited to, any familiar with this technology in the field of technical personnel in the utility model disclosed, within the limits of technology according to the technical scheme of the utility model and utility model idea to be equivalent to replace or change, should be covered within the scope of protection of the utility model.
