Abstract
The utility model belongs to lens technologies field, particularly a kind of rectangular light spot LED lens of uniform mixed light, and described lens comprise lens cup and are arranged at the minute surface of described lens cup side, and on described minute surface, dense arrangement has several rectangle cylindrical mirrors.Relative to prior art, the utility model is by several rectangle cylindrical mirrors of dense arrangement on minute surface, namely rectangle cylinder mirror microstructure array is formed at the specular surface of monomer lens, because rectangle cylindrical mirror is non-spherical lens, it can effectively reduce spherical aberration and aberration, thus the color temperature difference that the inhomogeneities can eliminating LED encapsulation itself in use causes, solve rectangular light spot illumination/Lux problem pockety, thus obtain a uniform rectangular light spot effect.
Description
Technical field
The utility model belongs to lens technologies field, particularly a kind of rectangular light spot LED lens of uniform mixed light.
Background technology
Service efficiency and the luminous efficiency of light can be strengthened together with namely LED lens are closely connected with LED, different lens can be used according to different effects to change the optical system of the optical field distribution of LED.
Due to the comparatively serious color temperature difference that the inhomogeneities of LED encapsulation itself causes, the lens that present market is sold, use time spot edge part all to there is the problem of macula lutea, locus coeruleus.And, the rectangular light spot illumination/Lux skewness that can form the lens of rectangular light spot commercially available at present.
The utility model aims to provide a kind of rectangular light spot LED lens of uniform mixed light, the color temperature difference that its inhomogeneities can eliminating LED encapsulation itself in use causes, and solves rectangular light spot illumination/Lux problem pockety.
Utility model content
The purpose of this utility model is: for the deficiencies in the prior art, and a kind of rectangular light spot LED lens of uniform mixed light are provided, the color temperature difference that its inhomogeneities can eliminating LED encapsulation itself in use causes, solves rectangular light spot illumination/Lux problem pockety.
To achieve these goals, the utility model adopts following technical scheme:
Rectangular light spot LED lens for uniform mixed light, described lens comprise lens cup and are arranged at the minute surface of described lens cup side, and on described minute surface, dense arrangement has several rectangle cylindrical mirrors.
One as the rectangular light spot LED lens of the utility model uniform mixed light is improved, and described minute surface is extended with the gradually little lug boss of diameter downwards, and one end of described lug boss is provided with cell body.
One as the rectangular light spot LED lens of the utility model uniform mixed light is improved, and the bottom of described lens cup is provided with latch post.
One as the rectangular light spot LED lens of the utility model uniform mixed light is improved, and described lens cup is cuboid-type, its one end open, and described lug boss is convex in described opening.
One as the rectangular light spot LED lens of the utility model uniform mixed light is improved, and described lens are concave lens.
One as the rectangular light spot LED lens of the utility model uniform mixed light is improved, and described rectangle cylindrical mirror is plano-convex cylindrical lens, and its protuberance is arranged outwardly.
One as the rectangular light spot LED lens of the utility model uniform mixed light is improved, and shares a limit between adjacent described rectangle cylindrical mirror.
One as the rectangular light spot LED lens of the utility model uniform mixed light is improved, and the lower end of described lens cup is provided with flange.
Relative to prior art, the utility model is by several rectangle cylindrical mirrors of dense arrangement on minute surface, namely rectangle cylinder mirror microstructure array is formed at the specular surface of monomer lens, because rectangle cylindrical mirror is non-spherical lens, it can effectively reduce spherical aberration and aberration, thus the color temperature difference that the inhomogeneities can eliminating LED encapsulation itself in use causes, solve rectangular light spot illumination/Lux problem pockety, thus obtain a uniform rectangular light spot effect.

Detailed description of the invention
Below in conjunction with embodiment, the utility model and beneficial effect thereof are described in further detail, but embodiment of the present utility model is not limited to this.
As shown in Figures 1 to 5, the rectangular light spot LED lens of a kind of uniform mixed light that the utility model provides, these lens comprise lens cup 1 and are arranged at the minute surface 2 of lens cup 1 side, on minute surface 2, dense arrangement has several rectangle cylindrical mirrors 3, namely rectangle cylindrical mirror 3 micro structure array is formed on the surface of the minute surface 2 of monomer lens, because rectangle cylindrical mirror 3 is non-spherical lens, it can effectively reduce spherical aberration and aberration, thus the color temperature difference that the inhomogeneities can eliminating LED encapsulation itself in use causes, solve rectangular light spot illumination/Lux problem pockety, thus obtain a uniform rectangular light spot effect.
Wherein, minute surface 2 is extended with the gradually little lug boss of diameter 21 downwards, and one end of lug boss 21 is provided with cell body 211, for covering LED lamp bead.
The bottom of lens cup 1 is provided with latch post 11, for being connected with miscellaneous part.
Lens cup 1 is cuboid-type, is convenient to the installation of rectangle cylindrical mirror 3, its one end open, and lug boss 21 is convex in opening.
Lens 2 are concave lens, the light that LED is sent optically focused well, make its brightness can reach reasonable effect.
Rectangle cylindrical mirror 3 is plano-convex cylindrical lens, and plano-convex cylindrical lens is only at a direction optically focused, and it can become a light into linear light, and its protuberance is arranged outwardly, as shown in Figure 5.
As shown in Figure 5, share a limit between adjacent rectangle cylindrical mirror 3, thus make the surface of whole minute surface 2 be covered with rectangle cylindrical mirror 3, do not stay any space.
The lower end of lens cup 1 is provided with flange 12, is convenient to the installation of lens cup 1.
In a word, the utility model is by several rectangle cylindrical mirrors 3 of dense arrangement on minute surface 2, namely rectangle cylindrical mirror 3 micro structure array is formed at monomer lens surface, because rectangle cylindrical mirror 3 is non-spherical lens, it can effectively reduce spherical aberration and aberration, thus the color temperature difference that the inhomogeneities can eliminating LED encapsulation itself in use causes, solve rectangular light spot illumination/Lux problem pockety, thus obtain a uniform rectangular light spot effect.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned embodiment and revise.Therefore, the utility model is not limited to detailed description of the invention disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this description, these terms just for convenience of description, do not form any restriction to the utility model.
