An exemplary lens includes a first light incident surface, a second light incident surface, a reflecting surface, a first light emitting surface and a second light emitting surface. The second light incident surface is connected with the first light incident surface. The first and the second light incident surfaces cooperatively define a receiving space therebetween. The receiving space is configured for accommodating the point light source. The reflecting surface is connected with the second light emitting surface. The first light emitting surface is opposite to the first light incident surface. Light entering the lens through the first light incident surface exits from the first light emitting surface. The second light emitting surface is connected between the first light emitting surface and the reflecting surface. Light entering the lens through second light incident surface is reflected from the reflecting surface to the second light emitting surface to exit the lens.
