Illumination apparatus |
摘要 |
An illumination apparatus including a light-emitting unit and a lens module is described. The light-emitting unit is used for generating a light and has a light exit axis. The lens module has a light exit surface with a plurality of curved surfaces. The lens module receives the light and outputs the light from the curved surfaces. Further, the curved surfaces have at least two curvatures, each for adjusting a illumination range of the light output from the corresponding curved surface.
