Abstract
A lens component includes: a light incident portion () having an incident face () upon which light from a light source () is incident, the light source () being disposed at a light source position (); and a plurality of plate-like light guiding portions () disposed radially around an axis (S) passing through the light source position () or a position in the vicinity thereof, and arranged to guide light incident from the incident face () of the light incident portion (), in emission directions (F, F-F) at right angles to the axis (S). Each of the plate-like light guiding portions () is provided on an end face () thereof with a radial reflecting face (A,B) for internally reflecting, in the emission directions (F, F-F), the light incident from the incident face () of the light incident portion (). Further, each of the plate-like light guiding portions () has a pair of main surfaces () forming a pair of light guiding and reflecting surfaces which extend substantially in parallel to the predetermined axis (S) and which guide, as internally reflecting, the light incident from the incident face () in the emission directions (F, F-F).
