On the rear surface of a transparent molded unit is provided a reflecting
member. In a central part of the molded unit are encapsulated light
emitting devices. In the vicinity of the central part of the reflecting
member is formed a reflecting area that is angularly inclined to the rear
surface as it moves to the outer circumferential direction. A toric
channel is provided on a light irradiation surface of the molded unit,
and a slope total reflection area is provided in its inner
circumferential side. Light emanating from the light emitting devices is
reflected at the slope total reflection area, and further reflected at
the direct output area. Then, after being further reflected at the
reflecting area of the reflecting member, the light is guided to the
outer circumferential end of the reflecting member, and is outputted
forward from the total reflection area by being reflected at the outer
circumferential end of the reflecting member.
