The first lens has a bottom surface with a first curved portion, a first flat surface and a side surface. The light source is configured for illuminating the first flat surface. The second lens has a top surface with a second curved portion, and a second flat surface. Wherein the cover is movable relative to main body between a first position where the second lens is away from the first lens such that the first flat surface is exposed, and a second position where the second flat surface faces towards the first flat surface and the second curved portion aligns with the first curved portion.
