    摘要: A beam-control member (170) has a substantially cylindrical holder (160) that is light-permeable, and a first beam-control member (140) disposed on an end surface (161) of the holder, the first beam-control member (140) reflecting part of the light emitted from a light-emitting element (130) and admitting part of the light. A guide protrusion (162) and a tab (163) are provided on the end surface (161) of the holder. A concave portion (144) corresponding to the tab (163) is provided on an outer circumferential part of one surface of the first beam-control member (140). The first beam-control member (140) is radially mated in a rotatable manner along the guide protrusion (162). Rotating the first beam-control member (140) on the end surface (161) of the holder so that the tab (163) and the concave portion (144) engage causes the first beam-control member (140) to be secured on the end surface (161) of the holder.
