[0005] 本发明为解决上述技术问题提出的技术方案是:一种LED护眼台灯透镜,包括台灯灯罩和用于扣合在台灯灯罩上的透镜本体,所述台灯灯罩上设有LED发光单元,所述透镜本体是由连接在一起的第一透明导光体部分和第二透明导光体部分构成,第一透明导光体部分朝向LED发光单元一侧的内表面呈弧形且密布有多条凸棱,第一透明导光体部分的两侧边向LED发光单元方向延伸并相互平行,所述第二透明导光体部分的两侧边处分别设有一对供所述灯罩扣合的卡槽。 [0005] The present invention is to solve the above problems is proposed solution: an LED lamp eye lens, comprising a lamp shade and a lens body for engaging on the lamp shade, the light emitting unit is provided on the LED lamp shade said lens body is composed of a transparent light guide portion and the second portion of the first transparent light guide connected together, a first transparent light guide portion toward the inner side of the LED lighting unit and clouds have curved surfaces a plurality of ribs, both side portions of the first transparent light guide edge extending parallel to the direction of the LED lighting unit, the second side of said transparent light guide portion are respectively provided with a pair of sides for engaging the globe the card slot.

[0006] 进一步的,所述第二透明导光体的外侧面为弧形,所述第二透明导光体的外侧面雾化成磨砂状。 [0006] Further, an outer side surface of the second transparent light guide body is curved, the outer surface of the second transparent light guide is atomized into a frosted.

[0007] 本发明的有益效果是: [0007] Advantageous effects of the present invention are:

本发明通过将传统的单层透镜设计成具有类双层结构,并且内表面设计成弧形,改变了不同照射角度下光线在透镜内的折射角度或传输距离。 By the present invention, a conventional single lens design to have a double structure type, and an arcuate inner surface is designed to change the transmission distance or the angle of refraction of light at different illumination angles within the lens.

[0008] 另外在靠近LED发光单元的内壁上设置有多条凸棱,运用菲涅尔透镜原理进一步的加强了照射均匀度。 [0008] Further a plurality of ribs provided on the inner wall close to the LED light emitting unit, using the principle of the Fresnel lens further enhance illumination uniformity.
