radiation angle (α1) and a second one of the at least two lenses (21, 22) of the
lens array (2) emitting a second cone-shaped
light beam (LB2) with a second
radiation angle (α2), wherein the first
radiation angle (α1) of the
first light beam (LB1) and the second
radiation angle (α2) of the second
light beam (LB2) are different and in that the holster (100) comprises a
locking mechanism (110) with a locking element (120) and an
