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 Figure 1 to Figure 3, a kind of LED lens eliminating macula lutea effect that the utility model provides, these lens comprise lens cup 1 and are arranged at the minute surface 2 of lens cup 1 side, minute surface 2 is densely covered with the compound eye structural 4 be made up of several ommatidiums 3, the area of ommatidium 3 increases from the center of minute surface 2 gradually to edge, the area of namely not all ommatidium 3 is all identical, but has the structure of gradual change.
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.One end of lens cup 1 is provided with opening, and lug boss 21 is convex to be arranged to opening.
The bottom of lens cup 1 is provided with latch post 12, for being connected with miscellaneous part.
The shape of ommatidium 3 is hexagon, pentagon or quadrangle, and adjacent ommatidium 3 shares, and there is not gap between adjacent ommatidium 3.
Minute surface 2 is Ao Xiang center gradually from edge, and the light that this concave structure can make LED send can optically focused well, makes its brightness can reach reasonable effect.
Compound eye structural 4 comprise the central eye 41 at the center being positioned at minute surface 2 and some corrals around central eye 41 arrange and the compound eye ring 42 be made up of ommatidium 3, several compound eye rings 42 are concentric setting, these compound eye rings 42 have " annual ring " shape structure, round and round to external diffusion.
The center of circle of each compound eye ring 42 all with the center superposition of central eye 41, to ensure the concentricity of compound eye structural 4, improve its condenser performance.
The shape of the ommatidium 3 on same compound eye ring 42 is identical, and area equation, and the shape of ommatidium 3 on different compound eye ring 42 is not quite similar, and area is then unequal.
The area being positioned at the ommatidium 3 on the compound eye ring 42 of outer ring is greater than the area of the ommatidium 3 on the compound eye ring 42 that is positioned within this outer ring, and the area namely the closer to the ommatidium 3 at the edge of minute surface 2 is larger, and the area the closer to the ommatidium 3 at the center of minute surface 2 is less.
The lower end of lens cup 1 is provided with flange 11, is convenient to the installation of lens cup 1.
The utility model by arranging the ommatidium 3 (area of ommatidium 3 increases from the center of minute surface 2 gradually to edge) with grading structure on minute surface 2, and then compound eye structural 4 is formed on minute surface 2, can eliminate or weaken the impact of aberration for hot spot of LED existence itself, can obtain evenly light mixing effect, thus the macula lutea effect effectively eliminated in hot spot, obtain uniform hot spot, realize Uniform Illumination.
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.
