Description

Lens module Technical Field The application relates to the technical field of light source refractors, in particular to a lens module. Background Along with the rapid development of semiconductor lighting technology, the LED lamp is widely applied to the indoor and outdoor lighting fields by virtue of the advantages of high efficiency, energy conservation, long service life and the like. In the design of an LED optical system, a lens module is used as a key optical element, and the structure of the lens module directly influences core performance indexes such as light efficiency distribution, glare control and the like. In the prior art, in order to realize the anti-glare lighting requirement, a structure of adding an independent reflecting cup on the outer side of a lens body is generally adopted, and the glare is reduced through a deep-hidden light source. However, the reflective cup is usually assembled with independent components and lenses, so that the overall thickness of the lens module is the thickness of the superposition of the heights of the lens base body and the reflective cup, and the light and thin design of the lamp is restricted. Disclosure of Invention The present utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, the utility model provides a lens module capable of compressing the height of a lamp, which adopts the technical scheme that: The utility model provides a lens module, includes the lens body, the lens body includes anti-dazzle cup, anti-dazzle cup's cup bottom is equipped with the arc recess that is used for holding the LED lamp, the cell wall of arc recess constitutes the income plain noodles of lens body, anti-dazzle cup's cup inner wall constitutes the play plain noodles of lens body. The technical scheme adopted by the embodiment of the utility model for solving the technical problems is that the inner wall of the arc-shaped groove is provided with a light mixing micro lens structure. The technical scheme adopted by the embodiment of the utility model for solving the technical problems is that the outer wall of the anti-dazzle cup is provided with a reflection microstructure. The technical scheme adopted by the embodiment of the utility model for solving the technical problems is that the lens body also comprises a base plate which is arranged around the cup opening of the anti-dazzle cup in a surrounding way. The technical scheme adopted by the embodiment of the utility model for solving the technical problems is that a micro lens structure is arranged on the substrate. The technical scheme adopted by the embodiment of the utility model for solving the technical problems is that the micro-lens structure is a micro-stripe lens structure. The technical scheme adopted by the embodiment of the utility model for solving the technical problems is that the anti-dazzle cup also comprises a mask arranged on the substrate, wherein the mask is provided with a cup-shaped through hole matched with the anti-dazzle cup, and the wall of the cup-shaped through hole is matched with the wall of the anti-dazzle cup.
