Abstract: A lens for an illumination device, in a cross section, includes a bottom surface, and a first side surface and a second side surface which respectively extend inclinedly upwards from two sides of the bottom surface and converge. The bottom surface includes a supporting surface and an incident surface, the incident surface defining an accommodation cavity for accommodating a light source of the illumination device. The first side surface includes a first emergent surface and a first reflective surface, the second side surface includes a second emergent surface. A first part of light from the incident surface emerges from the first emergent surface, and a second part of light from the incident surface at least emerges from the second emergent surface after reflected by the first reflective surface, such that the emergent light is distributed at an angle of 360°.
