Patent ID: 7445360

Claim:
A signal indicating light indicator unit ( 3 A- 3 C, 42 ) comprising: a lens component ( 7 , 7 A- 7 C, 7 F) comprising: a light incident portion ( 16 ) having an incident face ( 14 ) upon which light from a light source ( 6 ) is incident, the light source ( 6 ) being disposed at a single predetermined light source position ( 15 ); and a plurality of plate-like light guiding portions ( 17 , 32 ) extending radially outward from a predetermined axis (SO) passing through the single light source position ( 15 ) or a position in the vicinity thereof and arranged to guide light incident from the incident face ( 14 ) of the light incident portion ( 16 ), in radial emission directions (F, F 1 -F 3 ) intersecting the predetermined axis (SO), and wherein each of the plate-like light guiding portions ( 17 , 32 ) is provided on an end face ( 27 ) with a radial reflecting face ( 29 , 29 A, 29 B) for internally reflecting in the radial emission directions (F, F 1 -F 3 ), the light incident from the incident face ( 14 ) of the light incident portion ( 16 ), each of the plate-like light guiding portions ( 17 , 32 ) has a pair of main surfaces ( 25 ) serving as a pair of light guiding and reflecting surfaces which extend substantially and parallel to the predetermined axis (SO) and for guiding, as internally reflecting the light incident from the incident face ( 14 ) in the radial emission directions (F, F 1 -F 3 ), light from an outer periphery ( 13 ) of said plurality of plate-like guiding portions is radially emitted in said radial emission direction, a single light source ( 6 ) is disposed at the single light source position ( 15 ) of the lens component ( 7 , 7 A- 7 F), and said light incident face ( 14 ) comprises a concave portion and said single predetermined light source position ( 15 ) is provided in said concave portion.
