| 发明名称 | Light guide element for controlling light distribution and lamp | ||
| 摘要 | A light guide element and a lamp are provided. The light guide element includes a light-incident surface, a light-emitting surface, an outer surface and an inner surface. The light-incident surface has a first outer peripheral edge and a first inner peripheral edge. The light-emitting surface is opposite to the light-incident surface and has a second outer peripheral edge and a second inner peripheral edge. The outer surface connects the first outer peripheral edge and the second outer peripheral edge. The inner surface connects the first inner peripheral edge and the second inner peripheral edge. A first opening defined by the inner surface adjacent to the first inner peripheral edge is larger than a second opening defined by the inner surface adjacent to the second inner peripheral edge. | ||
