AI Technical Summary
Technical Problem
在公园、停车场等场景中灯具与地面之间的照明距离较短，其属于中低位照明场景，目前中低位照明场景通常采用道路使用的路灯等光照亮度大的LED照明产品进行照明，而这些光照亮度大的LED照明产品的光线直接从LED光源的正面射出，在照明距离短的情况下，光线过于集中、发光亮度不均匀、产生强烈的明暗反差的现象，造成中低位照明场景照明存在眩光明显的问题
Benefits of technology
[0014]本实用新型的有益效果在于：本实用新型提供的这种光学结构通过相对于反光杯的厚度方向倾斜贯通的收光孔，并且收光孔的内壁形成光型整合结构，通过光型整合结构的自由曲面对光源的大部分光能量进行偏转，使得出射光线不再集中于LED光源的出光方向或其他单一方向，自由曲面的反射让出射光线更分散，从而让发光亮度均匀，改善明暗反差现象，进而达到防眩光的效果。

Abstract
The utility model discloses a kind of optical structure, street lamp and projecting lamp, wherein optical structure includes reflector cup, the reflector cup is equipped with light-receiving hole, two ends of the light-receiving hole are formed light inlet and light outlet respectively, the through direction of the light-receiving hole is relatively the thickness direction of the reflector cup and is inclined to set, the inner wall of the light-receiving hole forms light type integration structure, and the light type integration structure includes free curved surface.The optical structure provided by the utility model is through the light-receiving hole that is inclined to pass through relative to the thickness direction of reflector cup, and the inner wall of light-receiving hole forms light type integration structure, deflects most light energy of light source by the free curved surface of light type integration structure, so that emergent light is no longer concentrated in the light direction of LED light source or other single direction, the reflection of free curved surface makes emergent light more dispersed, and the effect of anti-glare is achieved.
