摘要： Various embodiments relate to a lens for omnidirectional illumination being rotationally symmetrical and including a light incident surface, a first refractive surface, a first reflective surface, a second refractive surface, and a third refractive surface. A first portion of light which passed through the light incident surface is refracted by the first refractive surface to produce first emergent light. A second portion of the light which passed through the light incident surface is reflected by the first reflective surface to the second refractive surface, and then is refracted by the second refractive surface to produce second emergent light. A third portion of the light which passed through the light incident surface is refracted by the third light refractive surface to produce third emergent light, the first emergent light, the second emergent light and the third emergent light jointly achieved omnidirectional illumination.

摘要： Various embodiments relate to a lens for omnidirectional illumination which is rotationally symmetrical and includes a light incident surface, a first light refractive surface, a first light reflective surface, and a second light refractive surface designed to be rotationally symmetrical, respectively. The second light refractive surface is defined by a Bezier curve in a cross section, a first portion of light through the light incident surface is refracted by the first light refractive surface, a second portion of the light through the light incident surface is reflected by the first light reflective surface to the second light refractive surface, and then is refracted by the second light refractive surface, a third portion of the light through the light incident surface is refracted by the second light refractive surface, to produce first, second and third emergent lights, respectively. The first, second and third emergent lights jointly achieve omnidirectional illumination.
