Abstract: A lens may include a light incident surface, a first light emergent surface and side surfaces joining the light incident surface and the first light emergent surface. The light incident surface defines a space for accommodating light sources. The side surface includes at least one total-internal reflection surface and at least one second light emergent surface, a first part of light passing through the light incident surface is refracted by the first light emergent surface and emerges to generate first emergent light, a second part of light passing through the light incident surface is reflected by the total-internal reflection surfaces to the first light emergent surface and is refracted by the first light emergent surface and emerges to generate second light emergent light, and a third part of light passing through the light incident surface is refracted by the second light emergent surfaces and emerges to generate third emergent light.
